They are generally well tolerated, with a low incidence of adverse effects (1 %). Omeprazole is the most common PPIs used and its intake has tripled from 2003 to 2012 in Spain. Although hypersensitivity reactions to PPIs are rare, they are being more reported in recent years maybe due to the growing use of these drugs.</p><p>The aim of this study was to review our experience with the use of PPIs in the last 16 years.
</p><p><bold>Materials and methods:</bold> We undertook a retrospective analysis of 10,858 patients who attended to the Drug Allergy Unit of Hospital de la Cruz Roja-Madrid, from 1999 to 2014.</p><p>We divided our patients in two groups according to the increase of intake of PPIs.

Our results are according to the literature: Hypersensitivity reactions to PPIs are rare.</p></sec></sec></sec><sec id="Sec5"><title>P93 Allergy evaluation of quinolone induced adverse reactions</title><sec id="Sec6"><title>Jaume Martí Garrido, Carla Torán Barona, Carolina Perales Chorda, Ramón López Salgueiro, Miguel Díaz Palacios, Dolores Hernández Fernández De Rojas</title><sec id="Sec7"><title>IIS La Fe, Valencia, Spain</title><p><bold>Correspondence:</bold> Jaume Martí Garrido</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P93</p><p><bold>Background:</bold> The increasing use of quinolone antibiotics is associated with an increase in hypersensitivity reactions. The objective of this study is to analyse the cases of suspected allergy to quinolones referred to an allergy department in a tertiary level centre during 2015.</p><p><bold>Materials and methods:</bold> We performed a descriptive, retrospective study. Cases were identified from the medical record administrator programme by searching the terms “quinolone, norfloxacin, moxifloxacin, levofloxacin or ciprofloxacin”. We collected demographic and medical data, information of the adverse events, results of the allergy evaluation and the recommendations for the future use of quinolones.</p><p><bold>Results:</bold> We analysed 60 cases (26 male/34 female) with an average age of 60.5 years (6–88). The most frequent clinical manifestations were cutaneous (70 %), 11 % digestive, 7 % respiratory, 7 % neurological, 4 % cardiovascular and 1 % renal. The most common symptom were pruritus (25 %) and erythema (24 %). The reaction was immediate (within minutes) in 37 % and delayed in 45 %. The type of reaction was not described in 18 % of cases. The involved quinolones were ciprofloxacin (40 %), levofloxacin (37 %), norfloxacin (8 %) and moxifloxacin (8 %). The most frequent route of administration was oral (66 %), followed by intravenous (30 %), topical (2 %) and otic (2 %). In two cases quinolones were directly banned after the adverse event due to the patient clinical condition or it was not considered necessary due to the lack of evidence on the reliability of the tests. Skin tests were performed in 40 % of cases, with positive results for ciprofloxacin 78 %, moxifloxacin 77 %, levofloxacin 57 % and none for norfloxacin. In a case of a generalized delayed reaction, patch tests were negative. In one case a fixed drug erythema due to norfloxacin was diagnosed without further check. In 10 cases of severe immediate reactions, BAT was performed 17 times with 4 positive results for ciprofloxacin and 3 for levofloxacin. In these cases quinolones were banned. All patients tolerated alternative quinolones to the one eliciting the adverse event, even when skin tests were positive.</p><p><bold>Conclusions:</bold> Ciprofloxacin and levofloxacin were the most frequently involved quinolones. Skin symptoms were the most common clinical manifestations. Allergy evaluation included skin tests, BAT and controlled exposure in order to identify the responsible quinolones and search for safe alternatives. The sensitivity and specificity of these tests are still undetermined.</p><p><bold>Keywords:</bold> Quinolone; Allergy</p></sec></sec></sec><sec id="Sec8"><title>P94 Bupropion-induced acute urticaria and angioedema, a case report</title><sec id="Sec9"><title>Emre Ali Acar<sup>1</sup>, Ayse Aktas<sup>2</sup>, Aylin Türel Ermertcan<sup>3</sup>, Peyker Temiz<sup>4</sup></title><sec id="Sec10"><title><sup>1</sup>Celal Bayar University, Faculty of Medicine, Department of Internal Medicine, Manisa, Turkey; <sup>2</sup>Celal Bayar University, Faculty of Medicine, Department of Allergy and Immunology, Manisa, Turkey; <sup>3</sup>Celal Bayar University, Faculty of Medicine, Department of Dermatology, Manisa, Turkey; <sup>4</sup>Celal Bayar University, Faculty of Medicine, Department of Pathology, Manisa, Turkey</title><p><bold>Correspondence:</bold> Emre Ali Acar</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P94</p><p><bold>Background:</bold> Bupropion is a new-generation antidepressant, while its sustained release (SR) formulation is used in smoking cessation for a long time successfully.

We wanted to report a case with urticaria and angioedema due to SR bupropion treatment.</p><p><bold>Report:</bold> A-27-year-old woman without any disease history admitted to a hospital for smoking cessation. She had 15-pack-year of smoking history and she had started using 150 mg of SR bupropion. In first 3 days, she had used it once a day, then she started using twice a day. On tenth day of treatment, generalized rash with pruritus had been developed. In physical examination, she had generalized plaques and papules with edema and erythema on his neck, trunk, upper and lower extremites (Fig. <xref rid="Fig1" ref-type="fig">1</xref>). She had swelling on her lips as well. With suspicion of adverse drug reaction, skin biopsy was made. Other physical examination, blood and urinary laboratory findings were normal.

The former three have changes in their benzimidazole ring, whereas the latter three have changes in their pyridine ring. Although proton-pump inhibitors (PPI) are relatively well tolerated, some patients may develop hypersensitivity reactions, which vary from mild symptoms to life-threatening severe cutaneous adverse reactions (SCARs), such as Stevens–Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), acute generalized exanthematous pustulosis (AGEP), and drug rash with eosinophilia and systemic symptoms (DRESS). Clinicians often overlook the potential of PPI-related SCARs.</p><p><bold>Materials and methods:</bold> We retrospectively analyzed patients of PPI-related cutaneous adverse reactions from Chang Gung Memorial Hospital health system during January 2003 to December 2015. We analyzed the causative PPIs, cutaneous manifestation, organ involvement, treatment, and complications. We also assessed the cross-hypersensitivity to other PPI after the hypersensitivity episode. The causality of the culprit drugs was further confirmed by in vitro lymphocyte activation test (LAT) and patch test in some cases.</p><p><bold>Results:</bold> There were 48 cases of PPI-related cutaneous adverse reactions, with maculopapular eruption (MPE, n = 20), DRESS (n = 10), and SJS/TEN (n = 9), contributing the most. Esomeprazole was the most common causative PPI (n = 23, 47.9 %), and the liver was the most frequently involved internal organ (26.7 %). One patient (2.1 %) died of esomeprazole-induced TEN. Seven patients allergic to one group of PPI would able to tolerate the other different structured PPI group, whereas two patients showed cross-hypersensitivity when shifting to alternative PPI of the same group with similar structure. The drug causality and cross-reactivity were confirmed by lymphocyte activation test in 53.8 % patient of whom tested; besides, 2 of 5 patient with patch test performed showed corresponding result to the LAT.</p><p><bold>Conclusions:</bold> The clinicians should be cautious of PPI-related SCARs. The potential of cross-hypersensitivity to similar structured PPI should be aware of, and shifting to different structured PPI could be considered when PPI is the treatment of choice (Fig. <xref rid="Fig2" ref-type="fig">2</xref>).<fig id="Fig2"><label>Fig. 2</label><caption><p>Causative proton pump inhibitors, demographic data, and allergologic investigation of patients with PPI-SCARs</p></caption><graphic xlink:href="13601_2016_122_Fig2_HTML" id="MO2"></graphic></fig></p></sec></sec></sec><sec id="Sec14"><title>P97 Diagnostic work-up in suspected hypersensitivity to proton-pump inhibitors: looking at cross-reactivity</title><sec id="Sec15"><title>Fabrícia Carolino<sup>1</sup>, Diana Silva<sup>2</sup>, Eunice Dias De Castro<sup>1</sup>, Josefina R.

Specificity of skin tests has to be determined and there are currently no specific recommendations from the ENDA group. <bold>Aim:</bold> We present a consecutive case series of patients with suspected PPI HSR.</p><p><bold>Materials and methods:</bold> The present study is a case series of patients evaluated in our Drug Allergy Unit for suspected PPI HSR, in an 8-year period. CR in skin prick tests (SPT) and intradermal tests (IDT) was assessed using the commercially available parenteral PPI formulations (esomeprazole 20 mg/ml, omeprazole 4 mg/ml, pantoprazole 4 mg/ml) and crushed tablets in saline (lansoprazole 15 mg/ml, rabeprazole 10 mg/ml) for SPT. IDT were only performed with parenteral formulations (1/1000–1/1 dilutions), due to safety and accuracy reasons.</p><p><bold>Results:</bold> In the studied period, 19 patients (11 female; mean ± SD age 50.7 ± 14.2 years) were assessed for the suspected HSR. PPI were mainly prescribed for dyspepsia/stomach ache (n = 11) or <italic>Helicobacter pylori</italic> eradication (n = 4). Implicated PPI were omeprazole (n = 13), esomeprazole (n = 4), pantoprazole (n = 2), lansoprazole (n = 2), with 2 patients reacting to different PPI (omeprazole/lansoprazole and omeprazole/pantoprazole). Eight patients had immediate reactions (6 anaphylaxis and 2 urticaria) and 3 of them had positive SPT (one had positive SPT to both omeprazole and pantoprazole). Seven patients (5 urticaria, 1 anaphylaxis and 1 MPE) had positive IDT to omeprazole only (undiluted) and 1 patient (anaphylaxis) had a positive IDT to pantoprazole alone (1/100). Cutaneous CR (this is, positive IDT for >1 PPI) was present in 3 patients, as described below:<list list-type="bullet"><list-item><p>one patient with anaphylaxis to omeprazole and positive IDT to omeprazole (1/1000) plus esomeprazole (1/10);</p></list-item><list-item><p>another patient with anaphylaxis to omeprazole and positive IDT to omeprazole (1/10) plus pantoprazole (1/1);</p></list-item><list-item><p>and a patient with urticaria to esomeprazole and positive IDT to esomeprazole (1/10) plus pantoprazole (1/10).</p></list-item></list></p><p>Non-atopic controls were also tested for PPI.</p><p><bold>Conclusions:</bold> Cross-reactivity in 4 patients can be explained by the similar chemical structure of PPI.

ERT with human recombinant enzymes has shown to slow disease progression and improve the quality of life. Infusion-related reactions (IRR) to ERT can occur and be severe, including hypersensitivity reactions (HSRs) such as anaphylaxis. A diagnostic and treatment protocol was proposed to manage those reactions.</p><p><bold>Materials and methods:</bold> Patients under ERT for Mucopolysaccharidosis (I, II and VI), Gaucher, Fabry and Pompe diseases under treatment in 7 centers from Brazil were assessed from January 2011 through December 2015. In the presence of suggestive signs or symptoms of an adverse reaction, ERT was stopped and skin tests for specific IgE assay were performed. In patients with symptoms of acute infection after infusion and with negative skin tests, ERT was maintained at the same infusion rate. In patients without a history of infection and with negative tests, ERT was maintained with an increased infusion rate. For those patients with positive ST that continued reacting after adjustments in the IR, a 3 bags 12-steps desensitization protocol was generated.</p><p><bold>Results:</bold> Thirteen patients presented a suggestive HSR with positive skin tests, during treatment with laronidase (n = 3), galsulfase (n = 2), betagalsidase (n = 7), imiglucerase (n = 1). Urticaria was the most commom symptom observed (50 %), followed by fever (20 %), chills (10 %), cough (10 %) and anaphylaxis (10 %). Of the 911 desensitizations performed, 20 % induced mild reactions, but all patients received their full target dose. No severe, life-threatening HSRs or deaths occurred during the procedure.</p><p><bold>Conclusions:</bold> Considering the importance of ERT in the treatment of LD, a standardized diagnostic protocol for IRR allows us to establish a correct diagnosis and propose an efficient treatment algorithm, which includes infusion rate modification and desensitization.</p><p><bold>Keywords:</bold> Desensitization; Lysosomal diseases</p></sec></sec></sec><sec id="Sec20"><title>P99 Management of insulin allergy with continuous subcutaneous insulin infusion</title><sec id="Sec21"><title>Ceyda Tunakan Dalgiç, Aytül Zerrin Sin, Fatma Düsünür Günsen, Gökten Bulut, Fatma Ömür Ardeniz, Okan Gülbahar, Emine Nihal Mete Gökmen, Ali Kokuludag</title><sec id="Sec22"><title>Ege University Medical Faculty, Department of Allergy and Clinical Immunology, Izmir, Turkey</title><p><bold>Correspondence:</bold> Ceyda Tunakan Dalgiç</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P99</p><p><bold>Background:</bold> Insulin allergy is uncommon, particularly in patients with Type 2 diabetes mellitus (DM). Management of the condition can be difficult. We report a patient with Type 2 DM and insulin allergy successfully managed with continuous subcutaneous insulin infusion (CSII).</p><p><bold>Report:</bold> 35 years old woman diagnosed as type 2 diabetes mellitus used detemir insulin at first. On the third day of detemir, 12 h after the dose, a pruriginous papule occured at the site of injection area. Local reaction was continued. On the seventh day, detemir was changed with NPH. Local reaction occured at first dose of NPH. All of the local reactions were late onset. Therapy was changed to glargine. One hour after the first dose of glargine, local reaction and generalize pruritus were occurred. All insulin types were stopped and 4 weeks later, skin tests were performed. Prick tests were negative. Intradermal tests were positive with the dilutions of 1/100 detemir, 1/100 glargine, 1/1000 NPH, 1/1000 regular insulin. Glulisin, aspart and lispro were negative. Insulin specific IgE [194 Ku/l (0–87)] and anti-insulin antibody 47.8 % (reference <8.2) were high and specific Ig G4 was normal [35 mg/dl (0–125)]. The therapy started with glulisin and there wasn’t any reaction at first. Therefore, since blood glucose and serum glycated hemoglobin A1c levels (10 %) were still higher, as a long acting insulin, NPH had to be added together with antihistaminic. No reaction was observed with NPH. At the 20th day of glulisin, late onset local reactions were seen again. Glulisin was changed to aspart. Similar reactions were seen with those insulins. Finally, the only insulin which has never been used before was lispro. We suggested CSII pump with lispro. After this method, insulin hypersensitivity was successfully treated and glycemic control was achieved.</p><p><bold>How this report contributes to current knowledge:</bold> Allergy to insulin analogues is rare and requires early diagnosis, leading to a major therapeutic challenge. In this case, local reactions continued although types of insulins and application areas were changed. Interestingly, blood glucose was increasing to uncontrolled levels always following by the cutaneous reactions, also. As we consider anti-insulin antibodies and late onset local reactions, insulin allergy is thought to be mediated by type 1 and type 2 hypersensitivity reactions in this case.</p><p><bold>Consent:</bold> Written informed consent was obtained from the patient.</p></sec></sec></sec><sec id="Sec23"><title>P100 Off-label use of icatibant for management of serious angioedema associated with angiotensin inhibitors</title><sec id="Sec24"><title>Ana M.

Immediate hypersensitivity reactions are rarely reported and only two documented cases of immediate anaphylaxis are described in the literature. Moreover, the allergy diagnosis with validated skin tests is lacking.</p><p><bold>Materials and methods:</bold> We describe a first case of a 56-year-old woman that reported generalized pruritus, a rash involving palms and soles, dyspnea and colicky abdominal pain, 5 min after intramuscular (IM) administration of thiocolchicoside. These symptoms quickly reversed with IM adrenaline and intravenous (IV) hydrocortisone. A few months later we received a second case of a 52-year-old man who experienced dizziness, malaise and hypotension, 40 min after IM administration of thiocolchicoside and diclofenac. This clinical scenario was inverted with volume reposition with saline, IV hydrocortisone and adrenaline wasn’t administered.</p><p><bold>Results:</bold> In the first case the emergency lab results showed serum tryptase 47 μg/l. Skin Prick test (SPT) (2 mg/ml) was negative and 5 min after performing intradermal test (IDT) (2 mg/ml) the patient experienced throat tightness that was reversed with ebastine 20 mg. In the second case the SPT (2 mg/ml) was negative and IDT (2 mg/ml) was positive with a 7 mm wheal diameter. The skin tests and oral provocation with diclofenac were negative.</p><p>SPT and IDT with the same concentration were also negative in 6 patients with suspected immediate reaction to thiocolchicoside, confirmed by negative drug provocation test.</p><p><bold>Conclusions:</bold> Thiocolchicoside is often administered as an adjuvant therapy with non-steroidal anti-inflammatory drugs and is probably underestimated as a cause of immediate hypersensitivity reactions. Since the skin tests are not yet validated, many times it can be forgotten on the diagnostic workup. To our knowledge, this is the third study reporting documented anaphylaxis to thiocolchicoside and the first to support this diagnosis with intradermal tests.</p><p><bold>Consent:</bold> Written informed consent was obtained from the patient for publication of this abstract and any accompanying images.</p></sec></sec></sec></sec><sec id="Sec29"><title>Poster Walk 12: Betalactam hypersensitivity (P102–P111)</title><sec id="Sec30"><title>P102 A curious delayed reading: a case report of a β-lactam allergy in a child</title><sec id="Sec31"><title>Nicole Pinto, Joana Belo, João Marques, Pedro Carreiro-Martins, Paula Leiria-Pinto</title><sec id="Sec32"><title>Hospital de Dona Estefânia, Centro Hospitalar de Lisboa Central, Lisbon, Portugal</title><p><bold>Correspondence:</bold> Nicole Pinto</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P102</p><p><bold>Background:</bold> β-lactam antibiotics are commonly prescribed drugs worldwide and the most frequent cause of adverse drug reaction mediated by immunological mechanisms. Nonimmediate reactions, specially maculopapular and urticarial exanthems, are common.

The patient had been admitted to the hospital for acute mastoiditis. Upon admission, amoxicillin-clavulanic acid (Ax/C), which she had been taking for 4 days, was discontinued due to vomiting and she was started on triple IV antibiotherapy with ceftriaxone, vancomycin and metronidazole. On the 15th day of treatment, physical examination revealed a diffuse pruriginous maculopapular rash and fever, without palpable adenopathies. C-reactive protein was increased, eosinophil count was within normal range values and serologies for EBV and CMV were negative. An allergic reaction to ceftriaxone was suspected and the drug was discontinued by the 23rd day of treatment. Due to persistence of symptoms, the remaining 2 antibiotics were also discontinued 3 days later. Skin biopsy was suggestive of erythema multiforme and a course of systemic corticotherapy was started with resolution of symptoms. Skin prick tests and intradermal tests (IDT) with Ax/C, penicillin, cefuroxime and ceftriaxone were performed, using the maximal non-irritant dose, all of which were negative on immediate reading. 48 h later, both the prick and IDT were positive for Ax/C as well as the IDT for ceftriaxone.</p><p><bold>How this report contributes to current knowledge:</bold> Few nonimmediate reactions to cephalosporin are confirmed, due to the fact that most are caused by infections.

Penicillins were implicated in 62.5 % of cases. Almost all of immediate reactions were induced by penicillins. The hypersensitivity was selective to one betalactam in nearly half of cases.

Cross-reactivity patterns involving cefazolin suggest that cefazolin hypersensitivity is an isolated hypersensitivity.</p><p><bold>Objectives:</bold> As a first objective of this study, we sought to confirm whether the application of a higher than 2 mg/ml test concentration could increase skin test sensitivity, and add to the diagnosis of cefazolin hypersensitivity.

Allergic reactions to BL can be immediate (IgE reactions) and non-immediate reactions (T cell reactions). There are two major types of BL allergic patients: cross-reactive patients that are allergic to common BL ring and selective patients, allergic to side chains. In the last years, several cases of clavulanic allergic patients were described. Frequently, the reactions to clavulanic acid (CL) are immediate and, until now, there are only reports of selective reactions to CL.</p><p><bold>Materials and methods:</bold> The authors report two cases of unusual CL allergic patients. The patients were submitted to skin tests (ST) with penicilloylpolylysine (PPL), minor determinant mixture (MDM), amoxicillin (AX), CL (Diater laboratory), benzylpenicillin, ampicillin, cefuroxime, ceftriaxone, cefipime, determination of specific IgE to BL and oral provocation tests to alternative and culprit drugs.</p><p><bold>Results:</bold> 1st case: male, 45 years old, presented to our allergy clinic with maculopapular rash, 7 days after beginning treatment with amoxicillin-clavulanic acid (AX/CL) and ibuprofen for pharygintis. He had previously received AX/CL with good tolerance. Drug provocation with ibuprofen was performed with negative results. Specific IgE to BL were negative. ST with PPL, MDM, AX, benzylpenicillin and AX/CL were negative and the patient was performed an oral AX/CL drug provocation. On the 5th day after drug provocation, he developed a generalized maculopapular rash. ST with CL was performed with a positive late reaction in the intradermal test (20 mg/ml) and a new drug provocation only with AX was negative then.</p><p>2nd case: female, 40 years old described 2 previous allergic reactions: generalized urticaria 10 min after the intake of one AX tablet at 36 years and an episode of anaphylaxis 5 min after one AX/CL tablet at 39 years.

All BL currently available may cause these reactions. Immediate hypersensitivity (IH) reactions usually appear within 1 h of drug intake and are mediated by specific IgE (sIgE) antibodies. They can be evaluated by different methods: clinical history, skin tests (ST), in vitro quantification of sIgE and drug provocation tests (DPT). The determination of sIgE has safety advantages over ST and DPT, but has low sensitivity. ST should be performed with PPL, MDM, penicillin G, amoxicillin and ampicillin. If these are all negative, a DPT should be executed to ultimately confirm or exclude allergy.</p><p><bold>Materials and methods:</bold> Retrospective study that included patients who had undergone ST with PPL and MDM for investigation of BL allergy in 2014 and 2015. Data were then collected regarding the results of ST (PPL, MDM, penicillin G, amoxicillin, ampicillin and a cephalosporin), sIgE (penicillin G, penicillin V, ampicillin, amoxicillin and cefaclor) and DPT (to amoxicillin and/or a cephalosporin).</p><p><bold>Results:</bold> One hundred and one patients (24 % male), with a mean age of 42 years old. The suspected BL was: penicillin G (40), amoxicillin (37), cephalosporins (6), ampicillin (2) and unknown (16). Eleven percent of the patients had positive ST to PPL or MDM, with only 1 having positive sIgE. Five of these patients underwent ST with an alternative cephalosporin (cefuroxime): 2 were positive and 3 were negative. Two of these underwent DPT, that were negative. Out of 90 patients with negative ST to PPL and MDM, 55 were submitted to ST with ampicillin and/or penicillin G and/or amoxicillin, being positive in 7 % of the patients; they all had negative sIgE. ST with amoxicillin didn’t add any extra information. Out of 84 patients with negative ST, 36 proceeded to DPT, which were positive in 6 % of the cases. Twelve patients underwent ST with a cephalosporin, being positive in 2 (when the suspected BL was also a cephalosporin). IH to BL was confirmed in 19 % of the cases.</p><p><bold>Conclusions:</bold> Of the 19 cases of confirmed IH to BL, only 1 had positive sIgE, corroborating the extremely low sensitivity of the method. Only 19 % of the suspected cases of BL IH were confirmed, emphasizing the importance to refer patients to an Allergy Centre for investigation. Some patients never concluded the BL allergy study, and some are still undergoing. We highlight the need for new less expensive and time consuming tests, which would also reduce the number of dropouts.</p><p><bold>Keywords:</bold> Betalactam allergy; Immediate hipersensitivity</p></sec></sec></sec><sec id="Sec45"><title>P107 Diagnostic work-up of 410 patients with suspicion of betalactam antibiotic hypersensitivity</title><sec id="Sec46"><title>Filipe Benito-Garcia, Inês Mota, Magna Correia, Ângela Gaspar, Marta Chambel, Susana Piedade, Mário Morais-Almeida</title><sec id="Sec47"><title>CUF Descobertas Hospital, Lisboa, Portugal</title><p><bold>Correspondence:</bold> Filipe Benito-Garcia</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P107</p><p><bold>Background:</bold> The aim of this study was to characterize the activity developed at our drug allergy outpatients’ center with patients (pts) referred with suspicion of hypersensitivity (HS) to betalactam antibiotics (BL).</p><p><bold>Materials and methods:</bold> Retrospective analysis of clinical files, in vivo/in vitro test results and drug provocation tests (DPT) from January 2011 to December 2015. All pts were studied according to standardized diagnostic procedures of ENDA/EAACI: serum specific IgE (sIgE) (ImmunoCAP<sup>®</sup>, ThermoFisher) to penicillin G/V, amoxicillin and ampicillin; skin prick and intradermal tests (IDT) to PPL/MD (DAP<sup>®</sup>, Diater), penicillin G, amoxicillin and cefuroxime with immediate and delayed reading. Other penicillin derivatives/cephalosporins were tested if they were the culprit drug. DPT with culprit drug was performed if previous investigation was negative. In confirmed cases an alternative BL was tested.</p><p><bold>Results:</bold> 410 pts with suspicion of HS to BL were included: mean age was 34.6 (SD ±18) years, 21 % had <18 years and 68 % were female. Penicillins/derivatives were the main culprit drugs (314 pts), mostly amoxicillin (229 pts), 149 in association with clavulanic acid. Cephalosporins were mentioned by 42 pts, namely cefazolin (15 pts). Mucocutaneous symptoms were the most frequent manifestations (81 %); anaphylaxis occurred in 54 pts, 18 with loss of consciousness. HS to BL was confirmed in 88 pts (21.5 %), all with a DPT negative to an alternative BL. HS was excluded in 289 pts (70.5 %); 33 pts are under study. Confirmation of HS was made by: sIgE in 10 pts; skin testing in 65 pts and DPT in 13 pts (amoxicillin-11, clavulanic acid-2). Skin tests were positive to: amoxicillin-33, penicillin-16, PPL-15, MD-3, flucloxacilin-1 cefazolin-5, cefuroxime-1. Delayed reading of IDT was positive in 7 pts: penicillin-3, amoxicillin-4. A systemic reaction during skin testing occurred in 13 pts, in 3 with anaphylaxis: one child during IDT with amoxicillin (2.5 mg/ml) and 2 adults during IDT with amoxicillin (25 mg/ml).</p><p><bold>Conclusions:</bold> To investigate the suspicion of HS to BL is of outmost importance because in most of these pts allergological workup is negative and HS to BL is excluded. Although the majority of confirmed cases are IgE-mediated, in about one-fourth a non-IgE mediated mechanism seems to be involved (positive DPT or positive delayed reading of IDT). Systemic reactions during IDT and DPT also reinforce the need of referral these pts to specialized centers.</p><p><bold>Keywords:</bold> Adults; β-Lactams; Drug allergy; Children; Skin tests</p></sec></sec></sec><sec id="Sec48"><title>P108 Immediate selective hypersensitivity reactions to clavulanic acid</title><sec id="Sec49"><title>Alla Nakonechna<sup>1</sup>, Yurij Antipkin<sup>2</sup>, Tetiana Umanets<sup>2</sup>, Fernando Pineda<sup>3</sup>, Francisca Arribas<sup>3</sup>, Volodymyr Lapshyn<sup>2</sup></title><sec id="Sec50"><title><sup>1</sup>Royal Liverpool and Broadgreen University Hospitals NHS Trust, Liverpool, United Kingdom; <sup>2</sup>Institute of Pediatrics, Obstetrics and Gynaecology, Kiev, Ukraine; <sup>3</sup>Diater Laboratorios, Madrid, Spain</title><p><bold>Correspondence:</bold> Alla Nakonechna</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P108</p><p><bold>Background:</bold> Clavulanic acid (CLV) is b-lactamases inhibitor with weak antibacterial activity and low immunogenic capacity widely used in combination with beta-lactam antibiotics.

Adverse reactions to adalimumab are limited mainly to injection site, immediate systemic reactions are very rare. Generalise skin reactions to this antibody are around 1 %. Certolizumab is humanized from mouse, anti-TNF recombinant antibody with the same indications. Systemic adverse reactions to certolizumab is very rare, also.</p><p><bold>Report:</bold> We report a 59-year-old woman with spondylartritisi (SpA) who was treated with adalimumab every 2 weeks for 4 years. At the 4th year, adalimumab was changed to prefilled ready to use form. 30 min after the first application of this form, local reaction and also vomiting, dispnea, laryngeal edema, hipotension with generalise itching happened. Than adalimumab was stopped. Therapy was changed to certolizumab pegol. 30 min after the first injection of certolizumab, she had nause, dizziness and visual disturbances without skin reactions. 15 days later she injected the second certolizumab dosage and the same reactions repeated. She was referred to allergy clinic. Skin prick test with 50 mg/ml of adalimumab was found negative. Intradermal test with (5 mg/ml) 1/10 dilusion was 10/45 mm and 1/100 dilusion was 8/40 mm (histamin intradermal: 10/50 mm). Both skin prick and intradermal tests with certolizumab pegol were negative. Depending on the uncertainty of her history about certolizumab, drug provocation test was administered with total therapy dose. No adverse or allergic reaction occured during provocation. The patient was continued certolizumab therapy seamlessly.</p><p><bold>How this report contributes to current knowledge:</bold> Although adverse systemic reactions to adalimumab are rare, we describe a immediate systemic reaction to adalimumab; fully humanized recombinant biological. We thought the reaction was not due to the new form, because the contents are completely same. Allergic reaction after changing the form seems to be coinsidental. Alternative monoclonal antibodies should be searched for those patients.</p><p><bold>Consent:</bold> Written informed consent was obtained from the patient for publication of this case report and any accompanying images.</p></sec></sec></sec><sec id="Sec64"><title>P113 Allergy to local anesthetics: negative predictive value of skin tests</title><sec id="Sec65"><title>Ivana Cegec, Danica Juricic Nahal, Viktorija Erdeljic Turk, Matea Radacic Aumiler, Ksenija Makar Ausperger, Iva Kraljickovic, Iveta Simic</title><sec id="Sec66"><title>University Hospital Zagreb, Zagreb, Croatia</title><p><bold>Correspondence:</bold> Ivana Cegec</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P113</p><p><bold>Background:</bold> Although true allergy to local anesthetics (LA) is rare, patients often report unwanted reactions after the administration of LA, requiring allergy consultations.

Telephone follow-up visits were performed during December 2015. On the basis of the follow-up results, the NPV of skin tests was calculated.</p><p><bold>Results:</bold> Skin tests were performed using two or more LA (lidocaine in 50 patients, articaine in 35 patients, bupivacaine in 27 patients, articaine + adrenaline in 11 patients). All skin tests were negative. Subcutaneous challenge was performed with lidocaine in 41 pts, articaine in 7 pts, bupivacaine in 1 pt, and articaine + adrenaline in 1 pt. All patients had negative subcutaneous challenge. In the follow-up period 20 pts received LA, 20 pts have not received LA while 10 pts were unavailable for follow-up. Of the patients who received LA after testing, 19 had no reactions during exposure while 1 pt experienced a severe hypertensive reaction with generalized exanthema. The NPV of skin tests to LA was 95 %. NPV for subcutaneous challenge tests was not calculated due to incomplete data on specific LAs used in subsequent exposures.</p><p><bold>Conclusions:</bold> Skin tests to LA are safe and have an excellent negative predictive value which allows the selection of a local anesthetic that can be safely administered in the future.</p><p><bold>Keywords:</bold> Local anesthetics; Skin test; Hypersensitivity; Negative predictive value</p></sec></sec></sec><sec id="Sec67"><title>P114 Cutaneous adverse reactions of molecular targeted agents: a retrospective analysis in 150 patients in our department</title><sec id="Sec68"><title>Yukie Yamaguchi, Tomoya Watanabe, Megumi Satoh, Tomohiko Tanegashima, Kayoko Oda, Hidefumi Wada, Michiko Aihara</title><sec id="Sec69"><title>Yokohama City University Graduate School of Medicine, Yokohama, Japan</title><p><bold>Correspondence:</bold> Yukie Yamaguchi</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P114</p><p><bold>Background:</bold> Molecular targeted agents are widely used in various inflammatory and immune diseases and tumors. Differently from adverse reactions induced by conventional drugs, these drugs demonstrate various new types of adverse reactions. Some of events may be induced by cross-reactions related to the expression of the same antigen on different tissue. Immune imbalance caused by a depletion of specific antigen may be a trigger of unpredictable reactions. It is important to know the prevalence, clinical types, and severity of the side-effects in each drugs.</p><p><bold>Materials and methods:</bold> We retrospectively analyzed patients who visited our department due to cutaneous adverse reactions caused by molecular targeted agents from 2010 to 2015. Types of drugs, clinical features of cutaneous adverse reactions, and subsequent outcome were evaluated.</p><p><bold>Results:</bold> One hundred and fifty patients were evaluated in this study. High frequency agents were EGFR inhibitors (63 %), multikinase inhibitors (8 %), TNF-a inhibitors (6 %), and programmed death-1 (PD-1) inhibitors (5 %). Regarding clinical phenotypes, acneiform eruptions and perionychia were highly observed (68 %) mainly caused by EGFR inhibitors as the target antigen EGFR is also involved in skin homeostasis. Maculopapular drug eruption (10 %) and hand-foot syndrome (7 %) were observed in users of multikinases inhibitors and EGFR inhibitors. Of note, systemic drug eruption (erythroderma, erythema multiforme, maculopapular) was highly observed in patients treated with multikinase inhibitors. Psoriasis-like and palmoplantar pustulosis-like eruptions (5 %) were caused by TNF-a inhibitors and IL-6R inhibitors. Although the frequency was low, lupus-like reaction, vitiligo, and other unexpected reactions were caused by inhibitors of TNF-a or PD-1, supposedly those inhibitors lead to immune imbalance further causing autoimmunity and inflammatory reactions. As for the outcome, 85 % of patients continued molecular targeted agents, while 15 % of patients required discontinuation of the drug.</p><p><bold>Conclusions:</bold> Predicteable cutaneous reaction, like acneiform eruptions by EGFR inhibitors, would be possible to manage without discontinuation of the drug. Some drugs, such as immune checkpoint inhibitors, may cause unexpected immune responses. Since adverse reactions of molecular targeted agents are variable depending on drugs. It is important to recognize the function of targeted antigen, and close monitoring is recommended.</p><p><bold>Keywords:</bold> Molecular targeted agents; Biologics</p></sec></sec></sec><sec id="Sec70"><title>P115 Generalized paralysis induced by local lidocaine injection</title><sec id="Sec71"><title>Jaechun Jason Lee, Jay Chol Choi, Hwa Young Lee</title><sec id="Sec72"><title>Jeju National University School of Medicine, Jeju, South Korea</title><p><bold>Correspondence:</bold> Jaechun Jason Lee</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P115</p><p><bold>Background:</bold> Local anesthetics, such as lidocaine, are widely used for numbing.

Allergic reactions account for <1 % of all adverse reactions. Immediate reactions are rare. The aim of this study was to describe the main characteristics of the population with confirmed LA allergy among patients referred to our outpatient clinic for suspected hypersensitivity (HS) to LA.</p><p><bold>Materials and methods:</bold> Retrospective analysis of the medical files of patients with suggestive history of immediate HS reactions to LA, referred to our outpatient centre between January 2006 and December 2015. In order to confirm the diagnosis, we conducted skin prick tests and subcutaneous drug provocation test (DPT) with the undiluted commercial solution of the culprit or an alternative LA. DPT was performed in increasing doses, every 15 min, up to a cumulative dose of 3.6 ml. Sensitization to latex was excluded.</p><p><bold>Results:</bold> A total of 65 patients with history of an adverse reaction to LA underwent DPT, 75 % female with a median age of 44 years (±17.4). Only 5 patients (7.7 %) had positive DPT (lidocaine in 2 patients, mepivacaine in 2 patients and ropivacaine in 1 patient). Of those patients, 60 % were female and the median age was 35 years (±20.6 years). Sixty percent of the patients had past history of multiple surgical interventions (with general anesthesia) and allergic diseases, asthma and rhinitis being the most frequent. Cutaneous symptoms (urticaria and angioedema) were the main manifestation, in 4 patients (66 %). There was no registry of severe adverse reactions. All reactions started within 2 h following LA application and regressed spontaneously without any treatment. Sensitization to both lidocaine and mepivacaine was determined in 2 patients. Comorbidities such as hypertension (2 patients), diabetes (1 patient) and thyroid disease (1 patient) were also seen. Eighty-three percent of these reactions occurred during dental procedures and 60 % of these after administration of lidocaine.</p><p><bold>Conclusions:</bold> As stated in other studies, we find a low positivity rate to DPT. And our findings were similar to those found in the literature: adverse reactions to LA are more prevalent in the mid-age and with cutaneous symptoms being the most frequent manifestation of HS.

Adverse reactions are scarce. Hypersensitivity reactions are especially rare, accounting for <1 % of all adverse reactions. When a reaction occurs, an allergy work-up should be performed in order to exclude an allergic reaction or to identify an alternative drug.</p><p><bold>Materials and methods:</bold> Retrospective analysis of data from patients referred to our drug allergy unit with suspected LA allergy in the past 5 years. The analysis was performed using SPSS, version 21.</p><p><bold>Results:</bold> We studied 47 patients for suspected LA allergy (83 % females, with median age 49, and interquartile range 23). Six patients were atopic. Thirty-six percent of patients were referred by their family physician and 26 % by dentists.</p><p>Of the 47 patients, 38 % had a suspected reaction during a dental procedure, 14 % had positive patch tests with LA and 13 % had per-operative anaphylaxis. Considering the patients who had a suspected reaction, 74 % had immediate reactions. In 49 % of these cases, there was mucocutaneous involvement, 33 % had respiratory symptoms and 33 % vasovagal response. The LA used was known in 70 % of these cases, none of them were an ester. Lidocaine was the culprit in 20 cases, mepivacaine in 5, articaine in 5 and ropivacaine in 4.</p><p>Skin prick tests (SPT) and intradermal tests (ID) were performed with validated concentrations, without vasoconstrictor. Only 2 patients had positive tests: 1 positive SPT to mepivacaine and one positive ID to procaine; the other patient had a positive ID to ropivacaine.

Anamnesis excerption: Alcohol abuse for a long time. About 2 years ago, following one of patient’s drinking-bouts, episode with loss of consciousness emerged, qualified as secondary epilepsy; carbamazepine was administered. The patient described vesicular rash on lips and hands following the carbamazepine medication; he did not seek medical attention, though. The therapy was cancelled. Within 2 weeks the skin rash passed. The present episode had also been related with a prolonged period of alcohol ingestion, whereupon a detoxification treatment was administered, and, taking into account the possibility of episyndrome, carbamazepine was ordered, too. On the second day vesicular rash appeared on hands, thereupon in the scrotum area, on eyelids and on mucous tunic of mouth, forcing the patient to seek medical attention. Condition on admittance: of moderate gravity. Rash on hands with big serous fluid-filled vesicles; negative Nikolsky symptom. There were erosion with diapedetic bleeding and scrotal oedema in the area of scrotum and penis. Cheilitis, multiple aphthae on the internal surface of cheeks, on hard and soft palate and on tong were revealed, as well as haemorrhagic crustings on eyelids, moderate injection in scleral vessels. Physical state: with no specific findings. Systemic glucocorticoids and antihistamine preparations were administrated, as well as antibacterial, infusion therapy and topical treatment. On the second day a total relief of diapedetic bleeding in the scrotal area was achieved. To the end of the 10th day a total epithelization in the area of penis and scrotum occurred. Aphtae on hard and soft palate relieved totally within the first 3 days. Laboratory results have shown increasing levels in circulating thrombocytes according to the relief of diapedetic bleeding. Maximal levels were attained by the 6th day (667*109/l) with the following return to normal values. On admission C-reactive protein levels were elevated up to 136.65 mg/l, by the 7th day they returned to normal values.</p><p>No eosinophilia or leukocytosis had been revealed.

The reaction was immediate (within minutes) in 69 % of cases. One patient required admission to the intensive care unit and another had a repeated episode of anaphylaxis after readministration of RCM despite of the premedication. In 4 cases the reaction occurred during a computed tomography (CT), in 4 with intravenous urography (IVU), and 3 with magnetic resonance (MR). In 2 cases the radiological procedure was not specified. In 2 of the 13 patients (15 %), intradermal tests were positive with the RCM involved: iomeprol and dimeglumine gadopentetate.

Though considered generally safe, they can cause hypersensitivity reactions that can either be immediate or non-immediate. Anaphylactic shock reactions to ICM are rare but serious and could be life threatening. Hence, urgent and timely treatment should be administered.</p><p><bold>Report:</bold> We present a case of a 64 year old hypertensive patient with ischemic cardiopathy who presented with intense cephalic heat, tachycardia, hypoxemia and hypotension of 50/30 mmHg without any cutaneous lesions immediately after the administration of 35 g of Iomeprol contrast medium for cardiac catheterization. Epinephrine IM, Dexchlorpheneramine and corticosteroid IV and intravenous fluid therapy were administered which afforded the reversal of the hypotension. The tryptase at the time of the reaction and 2 h post reaction were both elevated, 85.70 and 88.70 μg/l respectively. Baseline tryptase was normal (6.86 μg/l). Skin prick test and basophil activation test to different contrast media were negative while intradermal test to Iomeprol showed a positive result and negative to Iohexol, Iodixanol and Meglumine. Thus, challenge test to Iodixanol reaching a total dose of 47 g as an alternative medium was done which he tolerated well. One month later, the patient underwent another cardiac catheterization. However, 10 min after the administration of 15 g of Iodixanol, he presented another episode of anaphylactic shock. He was given the same medications he had received previously which reversed the anaphylactic shock. Tryptase level was positive (30.20 μg/l). Due to the episode of anaphylactic shock, the contemplated cardiac catheterization was discontinued. Skin tests the next day resulted positive to Iohexol, Iodixanol and Iomeprol.</p><p><bold>How this report contributes to current knowledge:</bold> Despite that the patient tolerated well the challenge test with Iodixanol and skin test was negative, possible hypersensitivity reactions can still occur. Although challenge test is considered the gold standard in drug allergy, it can also provoke sensitisation to the drug or increase the sensitivity that could not be detected prior due to cross reaction. As of the present, the pathophysiological mechanism of these allergic reactions still needs to be exemplified.</p><p><bold>Consent:</bold> Written informed consent was obtained from the patient for publication of this abstract and any accompanying images.</p></sec></sec></sec><sec id="Sec89"><title>P121 Anaphylactic shock and cardiac arrest induced by gadolinium-based contrast agents</title><sec id="Sec90"><title>Beatriz Pola Bibián, Marina Lluncor Salazar, Gemma Vilà Nadal, Ana María Fiandor Roman, Javier Dominguez Ortega, Miguel Gonzalez Muñoz, Santiago Quirce Gancedo, Maria Rosario Cabañas Moreno</title><sec id="Sec91"><title>La Paz Hospital, Madrid, Spain</title><p><bold>Correspondence:</bold> Beatriz Pola Bibián</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P121</p><p><bold>Background:</bold> Gadobenate Dimeglumine and Gadoteric Acid are two gadolinium-based contrast agents that enhance the contrast images obtained by magnetic resonance imaging.

The first case is a 26-year-old woman with no previous drug allergy who developed dizziness, generalised erythrodermia and throat tightness, when a nuclear magnetic resonance with MultiHance (Gadobenate Dimeglumine) was being performed. On physical examination, she had hypotension, tachycardia, tachypnea, 69 % of basal oxygen saturation and generalized pulmonary hypoventilation. She recovered after treatment with corticosteroids and adrenaline. Nine months later the patient was referred to the allergy unit. The second case is a 51-year-old woman with a history of high blood pressure treated with betablockers, rhinoconjunctivitis and asthma due to sensitization to house dust mites and dog dander. Immediately after the intravenous infusion of Dotarem (Gadoteric Acid) she developed dizziness, loss of consciousness and cardiac arrest. On physical examination, she had universal rash without wheals, 90 % of basal oxygen saturation and generalized wheezing. CPR was started and 1 mg of Adrenaline was administrated.

Rare cases of hypersensitivity reactions to this drug have been published in the literature. The authors describe a case of systemic symptoms associated with GA and the diagnostic workup of the patient.</p><p><bold>Report:</bold> The authors report the case of a 34 year-old woman diagnosed with MS in 2008, initially treated with interferon-β1a (Avonex<sup>®</sup>). As relapses were frequent despite treatment, this was changed in January/2013 to natalizumab (Tysabri<sup>®</sup>), which is a monoclonal antibody (α4-integrin antagonist) with similar therapeutic indications to those described for GA. After 12 months of treatment, natalizumab was stopped because the patient developed persistent anti-drug antibodies. Considering that the patient was planning a pregnancy a new treatment (with GA) was started in March/2015. Four months later, the patient presented a generalized skin-burning sensation, dyspnoea and palpitations, 1 min after GA administration with no additional signs or symptoms. At this point, the patient was referred to our Drug Allergy Department for assessment. Skin tests were performed with GA plus the inactive ingredient of Copaxone<sup>®</sup> with allergenic potential, mannitol; the dilutions were prepared with saline solution. For skin prick tests we used GA 20 mg/ml in the 1/100, 1/10 and 1/1 dilutions, and mannitol 100 mg/ml (undiluted). Intradermal tests were performed with 1/1,000,000–1/10 dilution of GA (20 mg/ml), with a strong positive result at 1/10 concentration. Intradermal test to mannitol (1/10 dilution) was negative.</p><p><bold>How this report contributes to current knowledge:</bold> We also tested three (2 atopic and 1 non-atopic) controls for GA at 1/10 dilution with negative results.

She had been previously exposed to ICM with tolerance. In 2015, a new high-resolution CT scan was performed using the same ICM (iomeprol), and again a diffuse pruritic exanthema developed (6 h later) but this time with facial angioedema and fever (39 °C); the symptoms resolved in 4 days under medication (antihistamine and corticosteroid), leaving residual purplish lesions that eventually disappeared (after weeks).

Late reactions to iodinated contrast media are frequent. We describe the tests used for the diagnosis in this case.</p><p><bold>Report</bold></p><p><bold>Method:</bold> We report a case of a 74-year-old man admitted to the coronary unit with cardiac arrest. A cardiac catheterization was performed without complications. Three days later he received another cardiac catheterization and within 24 h he presented a generalized maculopapular exanthema with pruritus and facial angioedema. Over the next few days the body temperature rose up to 38.5 °C. Blood tests showed eosinophilia (1200/mcL), total white blood cell count 19000/mcL, neutrophils 16,700/mcL, renal impairment (creatinine 1.89 mg/dl, previously being normal). The contrast used for catheterization was iodixanol. The patient also received ticagrelor, carvedilol, enalapril, furosemide, fondaparinux and lorazepam. Assessment of causality was established using the Spanish Pharmacovigilance System Algorithm. Results were (+6) “probable” for iodixanol and (+4) “possible” for carvedilol and ticagrelor. A multidisciplinary group composed by a dermatologist; a pharmacologist and an allergist evaluated the patient. This case was included in the Piel en RED registry. Six months after the reaction the patient was referred to the allergy unit and tests were performed. The allergy study included epicutaneous tests and the lymphocyte transformation test (LTT) according to Pichler et al. An stimulation index (SI) was calculated.</p><p><bold>Results</bold>: The diagnosis of a “probable” DRESS was established according to the scoring system described by Kardaun et al. Our patient received a score of 4. A skin biopsy showed spongiotic dermatitis with eosinophils. The patient had a positive LTT to iodixanol; the SI was over 8 in two concentrations. LTT showed also positive results for other iodinated contrast media. We also tested carvedilol and ticagrelor with a lightly positive result. Epicutaneous test showed remarkable positivity to iodixanol beginning at the 48 h reading. The test was negative to carvedilol, iobitridol and iomeprol.</p><p><bold>How this report contributes to current knowledge:</bold> LTT and patch test were useful to identify this agent as responsible for the reaction.

To avoid this, ‘consultation support system for RCM hypersensitivity’ has been embedded to Seoul National University Bundang Hospital (SNUBH) since Dec 2011. We analyzed the influence of this system on doctors’ practice pattern.</p><p><bold>Materials and methods:</bold> A retrospective study was conducted with the patients with previous RCM reactions (Dec 1st 2010–Nov 30th 2012). Control period was between Dec 2010 and Nov 2011 and intervention period was Dec 2011 and Nov 2012. Primary outcome was composite outcome of premedication and consultation. Premedication was defined as the preventive medication prescribed by the doctor who ordered RCM enhanced CT (CT) at the same time. Secondary outcomes were the recurrence rate after the consultation support system and ther rate of premedication using systemic steroid for those with previous history of moderate to severe RCM reactions.</p><p><bold>Results:</bold> In the control period, 189 clinicians prescribed 913 CT scans and 225 clinicians did 1.153 examinations in the intervention period. The odds of achieving composite outcome increased significantly after the consultation support system (OR 1.54, 95 % CI 1.15–2.05). Clinicians in both medical (OR 1.48, 95 % CI 1.06–2.07) and surgical (OR 2.07, CI 1.24–3.46) part showed significant changes in their behavior, but emergency department did not (OR 1.07, 95 % CI 0.41–2.78). Professors (OR 1.47, 95 % CI 1.06–2.04) and trainees (OR 1.97, 95 % CI 1.22–3.18) showed significant changes in their behavior to the patients with previous RCM reactions. The rate of premedication using systemic steroid for the patients with previous history of moderate to severe RCM reactions did not changed significantly (OR 1.68, 95 % CI 0.70–0.404). The results of analyses with 86 clinicians who ordered CT scans during both control and intervention periods were not altered.</p><p><bold>Conclusions:</bold> The consultation support system for those with previous RCM hypersensitivity reactions changed doctor’s practice patterns and decreased recurrent RCM hypersensitivity reactions as well.</p><p><bold>Keywords:</bold> Drug hypersensitivity; Radiocontrast media; Clinical decision supporting system</p></sec></sec></sec><sec id="Sec107"><title>P127 Hypersensitivity reactions to iodinated contrast media: skin testing and follow-up</title><sec id="Sec108"><title>Danica Juricic Nahal, Ivana Cegec, Viktorija Erdeljic Turk, Iva Kraljickovic, Matea Radacic Aumiler, Ksenija Makar Ausperger, Iveta Simic</title><sec id="Sec109"><title>University Hospital Zagreb, Zagreb, Croatia</title><p><bold>Correspondence:</bold> Danica Juricic Nahal</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P127</p><p><bold>Background:</bold> Iodinated contrast media (ICM) are frequently used to enhance radiological procedures. Hypersensitivity reactions to ICM can be classified as immediate or nonimmediate. Skin tests have been performed in the diagnosis of both types of reactions to ICM. The sensitivity of skin tests has not been adequately validated.</p><p><bold>Materials and methods:</bold> A retrospective chart review was performed on patients (pts) undergoing ICM skin testing. A total of 45 pts tested for ICM allergy at the Division of Clinical Pharmacology at the University Hospital Zagreb between July 2014 and October 2015 were enrolled. All pts underwent skin tests (prick test and intradermal test with immediate and delayed reading) to iohexole and/or iodixanole. Pts were contacted during December 2015 and questioned about exposure to ICM after testing. Eligible pts (n = 40) were classified into three groups: nonimmediate or immediate hypersensitivity reaction to ICM, and previously unexposed group.</p><p><bold>Results:</bold> The nonimmediate group comprised 15 pts with hystory of exanthema (53.3 %), urticaria (20 %), angioedema (13.3 %) and pruritus (6.7 %) to ICM. One pt had positive skin tests to iodixanole and negative to iohexole. All other performed tests were negative. In the follow-up period 4 pts were exposed to ICM without adverse reactions; 10 pts were not exposed to ICM; 1 pt was unavailable for follow up.</p><p>The immediate group comprised 11 pts with hystory of gastrointestinal symptoms (27.3 %), urticaria (27.3 %), angioedema (18.2 %), general symptoms (18.2 %) and flush (9.1 %) to ICM. One pt tested positive to iohexole. All other performed tests were negative. In the follow-up period 7 pts were exposed to ICM; 6 pts experienced no adverse reactions; 4 pts were not exposed to ICM and 1 pt developed angioedema.</p><p>The previously unexposed group comprised 14 pts. All skin tests were negative. The reason for referral to ICM testing was a hystory of serious allergic reaction to different allergens. In the follow-up period 5 pts were exposed to ICM without adverse reactions; 4 pts were not exposed to ICM; 5 pts were not available for follow up.</p><p><bold>Conclusions:</bold> Overall, 16 pts were exposed to ICM in the follow-up period and of those, 1 pt developed an immediate reaction. The calculated negative predictive value in this study is thus 93.8 %.</p><p>This study adds further knowledge to the field of ICM hypersensitivity.

The iodine allergy is a mythical entity, but nevertheless!</p><p><bold>Materials and methods:</bold> A 39 year old diabetic man, with end stage renal disease undergoing peritoneal dialysis, was referred for immediate hypersensitivity (IH) reactions. Betadine dermique<sup>®</sup> containing povidone iodine triggered an immediate contact pruritic rash disappearing in 30 min (mns). Angioedema and urticaria occurred a few mns after ingestion of shrimps, mussels, oysters, whelks, trout and salmon. Awaiting kidney transplant, having never received RCM, a predictive assessment of RCM IH was required. Patch and prick tests (pt), IDT, specific IgE and RCM reBackground were performed under hospital supervision.</p><p><bold>Results:</bold> While all patch tests were negative, pt were positive for pure Betadine dermique<sup>®</sup> and iodized alcohol at 1 % in water but negative for Lugol 2 % (potassium iodide) and PV. Pt to a native oyster was positive but negative for crab, mussel and shrimp. IgEs were negative for salmon, mussel, oyster and shrimp. Pt and IDR were negative for iobitridol, ioxaglate and iodixanol in pure form (use concentration), but the intravenous administration of 1 ml iobitridol induced a generalized pruritus, a trunk and face erythema with ear edema, occurring after 30 mns and resolution in 60 mns after treatment with intravenous methylprednisolone and antihistamines.</p><p><bold>Conclusions:</bold> This exceptional case of multiple reactivities to iodine products and oyster suggests that for this patient iodine itself could be the common allergen. The positive pt to oyster is probably not related to a tropomyosin sensitization. Unlike previous published cases of allergy to povidone iodine, in this case the IH does not appear due to PV. While IDT was negative, iobitridol induced an immediate reaction. We emphasize (1) in case of PVI IH, the need to do a pt to PVI and PV before concluding to the lack of iodine sensitization and thus allow RCM; (2) if negative IDT with RCM, we must continue investigations by an intravenous Background test with a limited volume of RCM and (3) even if it is exceptional, an iodine allergy may exist. Investigations are continued with in vitro tests.</p><p><bold>Keywords:</bold> Allergy; Iodine; Multiples reactivity</p><p><bold>Consent:</bold> Written informed consent was obtained from the patient for publication of this abstract and any accompanying images.</p></sec></sec></sec></sec><sec id="Sec113"><title>Poster Walk 15: MPE/type 4 (P129–P137)</title><sec id="Sec114"><title>P129 Delayed hypersensitivity cutaneous reactions: a case/control study from a tunisian database</title><sec id="Sec115"><title>Karim Aouam, Najah Ben Fadhel, Zohra Chadly, Nadia Ben Fredj, Naceur A.

Diagnostic procedures rely on clinical history, skin testing and in some cases, provocation tests. Drug imputability is still difficult to establish due to the weakness of sensitivity of some skin tests and the impossibility to perform provocation test in case of severe reactions. The aim of our study is to evaluate delayed-type cutaneous allergic reactions associated with drug use.</p><p><bold>Materials and methods:</bold> The data were obtained from a Tunisian pharmacovigilance database of adverse drug reactions (ADRs). Analyzed reports were retrieved from the pharmacovigilance unit of Monastir (Tunisia) database collected from 2004 to 2015. The association between drugs and skin reactions was assessed using the case/non-case method, calculating the adverse reaction reporting odds ratio (ROR) and their 95 % confidence intervals as a measure of disproportionality. The “cases” were defined as reports of type III and IV skin allergic reactions (according to gelle and Coombs classifications). The “non-cases” were all other reports.</p><p><bold>Results:</bold> Overall 1800 reports of adverse reactions related to drug use were analyzed; of which 1523 (84 %) were judged as type III and IV skin allergic reactions (cases) and the remaining were considered non-cases. Drug classes associated with a significant increase of ROR were anticonvulsive agents [ROR = 2.2, 95 % CI (1.4–3.3), p < 10<sup>−3</sup>] and antibacterial drugs [ROR = 1.6, 95 % CI (1.3–2), p < 10<sup>−3</sup>]. Among antibacterial agents, betalactams were associated with a significant ROR [1.5; 95 % CI (1.2–1.8), p < 10<sup>−3</sup>]. Regarding betalactams, only oxacilline and the third generation cephalosporins were associated with a significant risk [ROR = 1.9; 95 % CI (1.1–3.2), p = 0.01] and [ROR = 1.81; 95 % CI (1.3–2.4), p < 10<sup>−3</sup>], respectively, while only carbamazepine [ROR = 3; 95 % CI (1.6–5.7), p < 10<sup>−3</sup>] and phenobarbital [ROR = 2.3; 95 % CI (1.1–5.2), p = 0.03] have shown a significant ROR values among anticonvulsive agents.</p><p><bold>Conclusions:</bold> Results highlight the frequency of association of delayed hypersensitivity skin reactions with betalactams, carbamazepine and phenobarbital.

Benzylpenicillin, the major responsible for BL drug allergic reactions, has been progressively replaced by amoxicillin and to a lesser extent by cephalosporins or other BL. Our aim was to characterize a series of subjects with suspected nonimmediate hypersensitivity (NIH) to natural penicillins and aminopenicillins/clavulanic acid (CA) and evaluate the usefulness of different diagnostic procedures in the study of these reactions.</p><p><bold>Materials and methods:</bold> A total of 391 patients with suspected betalactam hypersensitivity (BH) were referred to our department from 2009 to 2015 and those with suspected NIH to natural penicillins and aminopenicillins/CA were evaluated. Demographic data, atopy, allergic diseases, comorbidities, clinical manifestations and diagnostic procedures were assessed. BH was confirmed by positive skin tests (ST), drug provocation test (DPT) or long term-challenge (LTC) and considered probable based on a suggestive history and/or positive lymphocytic transformation test (LTT). ST were performed with PPL, MDM, Amoxicillin, Amoxicilin/CA, Ampicillin and Penicillin G; DPT was performed with Amoxicillin, Amoxicilin/CA and Penicillin.</p><p><bold>Results:</bold> 169 (43 %) patients had suspected NIH to natural penicillins and aminopenicillins/CA: 67 % female; median age 37 years (1–81); 34 % atopic; 16 % had rhinitis/rhinoconjunctivitis, 14 % asthma/rhinitis and 8 % chronic urticaria/angioedema. Cutaneous reactions were reported by 84 % of patients. Skin prick tests were negative in all patients tested (129). Intradermal tests were performed in 110 patients and 11 had positive late-reading.

Previous cases of fixed drug eruptions (FDE) from ornidazole were reported in the literature (1–6), however, in only one of them the diagnosis has been confirmed by a positive patch test (5); their patient had also shown a FDE following oral intake of fluconazole (5). In another case (6) cross-reactivity occurred following oral intake with secnidazole.</p><p>A 40-year-old male patient presented with two pigmented lesions, one on the upper arm, and one with a central erosion on the glans penis. These had occurred since the intake of ornidazole (Tiberal<sup>®</sup>, Laboratoires SERB, Paris, France) and budesonide (Entocort<sup>®</sup>, AstraZeneca, Brussels, Belgium), 2 weeks previously. The provisional diagnosis of FDE was put forward.</p><p><bold>Materials and methods:</bold> Five weeks later, patch tests with ornidazole (tablet crushed and diluted 30 % in petrolatum) and budesonide (0.01 % in petrolatum) were performed on a residual pigmented lesion on the upper arm, and also on a non-lesional skin site as a control, using vander Bend Chambers<sup>®</sup> (vander Bend, Brielle, The Netherlands).</p><p><bold>Results:</bold> Only the patch test with ornidazole on the residual pigmented lesion showed a positive reaction at day 4, while the control on the non-lesional skin remained negative. Discontinuation of ornidazole resulted in clearance of the lesions.</p><p><bold>Conclusions:</bold> In the unlikely event of a fixed drug eruption, clear identification of the culprit may be difficult, in particular when multiple medications are administered.

In vivo tests are inconvenient and in vitro tests are neither sensitive nor validated.</p><p>We describe a case of recurrent delayed reactions related to therapy with amoxicillin and amoxicillin clavunalate by in vivo and in vitro tests.</p><p><bold>Materials and methods:</bold> The patient developed repeated episodes of generalized skin rash, pruritus, malaise, chest pain and dysphagia after 5–7 days of therapy with amoxicillin clavunalate or amoxicillin. Blood tests showed an elevation in CRP, GGT, fibrinogen and monocytosis during the acute phase. The reactions resolved with corticosteroids and antihistamines.</p><p>Intradermal and patch tests were performed with amoxicillin and amoxicillin-clavunalate. Total IgE and specific IgE and IgG to amoxicillin were measured by ImmunoCAP<sup>®</sup>. Cell activation analysis by the culprit drugs and clavulanate was performed by flow cytometry. Basophil Activation Test (BASOTEST<sup>®</sup>) was considered positive if activation ≥5 % or SI (stimulation index) ≥2. Mononuclear cell activation was evaluated by the expression of CD69 after drug exposure for 48 h. Antibodies anti-CMV, Herpes, Epstein-Barr and parvovirus were analyzed.</p><p><bold>Results:</bold> Intradermal and patch tests with amoxicillin and amoxicillin clavunate acid were negative. Total IgE: 198 kUI/l. Specific IgE for amoxicillin and penicillin were negative (0.07 kUI/l). Specific IgG was 3.42 mgA/l. Basophil activation test was positive for amoxicillin (1/160: 10.87 %; SI 16.73–1/40: 48.55 %; SI 35.69) and amoxicillin clavunalate (1/160: 22.76 %; SI 16.73–1/40: 74.68 %; SI 54.91), but negative for clavunalate (100 μg/ml: 3.55 %; SI 1.26–200 μg/ml: 3.98 %; SI 1.41). A threefold increase occurred when the mononuclear cells were treated with amoxicillin, 2.5-fold increase with clavulanate and tenfold increase when the samples were treated with amoxicilline clavunalate. Serologies showed positive IgG for Epstein-Barr, herpes and parvovirus.</p><p><bold>Conclusions:</bold> Delayed adverse reactions to amoxicillin and amoxicillin clavulanate may be diagnosed by alternative tests such as basophil and lymphocyte activation tests when conventional in vivo and vitro tests show negative results. We hypothesize that specific IgG may induce anaphylactic reactions through basophil activation. Although the role of T cell activation is not clear, we observed a synergic effect of both drugs.</p><p><bold>Consent:</bold> Written informed consent was obtained from the patient for publication of this abstract and any accompanying images.</p></sec></sec></sec><sec id="Sec138"><title>P137 Systemic photosensitivity from fenofibrate in a patient photo-sensitized to ketoprofen</title><sec id="Sec139"><title>Liesbeth Gilissen, An Goossens</title><sec id="Sec140"><title>University Hospitals Leuven, Leuven, Belgium</title><p><bold>Correspondence:</bold> Liesbeth Gilissen</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P137</p><p><bold>Background:</bold> Fenofibrate is widely used in the treatment of hypercholesterolemia and hypertriglyceridemia.

Skin is the most commonly affected organ and NSAIDs-induced urticaria/angioedema (NIUA) the most frequent clinical entity.

The recent identification of human leukocyte antigen (HLA)-A*33:03 as a susceptibility factor and the delayed nature of the liver injury are both indicative of an immune pathogenesis. However, the role of the adaptive immune system in ticlopidine-induced DILI has not yet been defined.</p><p>The aim of this study was to investigate whether drug-specific T cell responses could be detected in healthy volunteers who expressed HLA-A*33:03. Any T cell responses would then be fully characterized for drug specificity, HLA restriction and the mechanism(s) of antigen presentation</p><p><bold>Materials and methods:</bold> Peripheral blood mononuclear cells were isolated from HLA-typed healthy volunteers who did or did not express the risk allele: HLA-A*33:03. Subsequently, naïve T-cells were separated and co-cultured with autologous monocyte-derived dendritic cells (DCs) in the presence of the ticlopidine for a period of 8 days, to expand the number of drug-responsive T-cells. T-cells were then harvested and incubated with freshly prepared dendritic cells and drug to test their antigen specificity using readouts for cell proliferation and cytokine secretion. T-cell clones were also generated following priming and drug-specific T cell clones analysed for cytokine secretion and HLA restriction.</p><p><bold>Results:</bold> Using the DC priming assay all four HLA-A*33:03 positive donors showed ticlopidine-specific proliferation and IFNγ secretion. However, no ticlopidine-specific responses were detected in HLA-A*33:03 negative donors. Around one thousand CD8 positive clones were generated from three HLA-A*33:03 positive donors, but ticlopidine specific clones were only obtained from one donor. These CD8 positive clones showed ticlopidine-specific IFNγ secretion. This response was restricted by HLA-A*33:03 and was not dependent on the presence of antigen presenting cells.</p><p><bold>Conclusions:</bold> In conclusion, ticlopidine-specific T-cells were detected in healthy volunteers expressing the risk allele HLA-A*33:03 using the DC priming assay.</p></sec></sec></sec><sec id="Sec151"><title>P141 Epistasis approaches to identify novel genes potentially involved in NSAIDs hypersensitivity</title><sec id="Sec152"><title>James Richard Perkins<sup>1</sup>, Jose Antonio Cornejo García<sup>1</sup>, Oswaldo Trelles<sup>2</sup>, Inmaculada Doña<sup>3</sup>, Esther Barrionuevo<sup>3</sup>, María Salas<sup>3</sup>, María Auxiliadora Guerrero<sup>3</sup>, Miguel Blanca<sup>3</sup>, Alex Upton<sup>2</sup></title><sec id="Sec153"><title><sup>1</sup>Research Laboratory, IBIMA, Regional University Hospital of Malaga, UMA, Malaga, Spain; <sup>2</sup>Department of Computer Architecture, University of Malaga, Malaga, Spain; <sup>3</sup>Allergy Unit, IBIMA, Regional University Hospital of Malaga, UMA, Malaga, Spain</title><p><bold>Correspondence:</bold> James Richard Perkins</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P141</p><p><bold>Background:</bold> A handful of genome wide association studies (GWASs) have been performed to detect genetic variation associated with NSAID hypersensitivity, by comparing the frequencies of hundreds of thousands of single nucleotide polymorphisms (SNPs) between NSAIDs hypersensitive subjects and control individuals. This is done on a SNP-by-SNP basis, meaning that each variant is considered independently. However, the effect of a single SNP on phenotype is influenced by other factors, including the individual’s genetic background. An alternative approach to analyse this data is the use of epistasis methods, which look for associations between pairs of SNPs and a phenotype that are stronger than the sum of the individual SNP-phenotype associations, suggesting an interaction between the SNPs.</p><p><bold>Materials and methods:</bold> We analysed data from an NSAIDs hypersensitivity GWAS using an epistasis detection method, MBMDR. The resulting pairs of interacting SNPs were used to build networks, both at the SNP level and at the gene level, by mapping SNPs to their closest protein coding gene (within 500 kb). These networks were analysed to identify SNPs and genes with a potential role in NSAIDs hypersensitivity using graph metrics. This approach identifies important hub nodes based on the strength and number of connections they have, which can be interpreted as the number of distinct pair-wise interactions they are involved in.</p><p><bold>Results:</bold> Our approach identified a number of genes with potential roles in NSAIDs hypersensitivity, including genes potentially involved in asthma (<italic>KCNB2</italic>, <italic>PPP1R3C and CSMD1</italic>), rhinitis (<italic>SCN11A</italic>) and immune system functioning (<italic>TSPAN33</italic>).

The gene <italic>CGNL1, whose expression has been shown to change following</italic> aspirin intake, was also identified. Additionally, pathway analysis of the networks found enrichment for ALK1 and TGF-beta signalling.</p><p><bold>Conclusions:</bold> The study presented here shows how weighted epistatic analysis approaches can complement traditional SNP-by-SNP analyses. Additional studies are necessary to replicate these findings, and they should be applied to other NSAIDs hypersensitivity pathologies. Moreover, the mechanisms by which the SNPs and genes identified here affect NSAIDs hypersensitivity must be investigated further.</p><p><bold>Keywords:</bold> NSAIDs-hypersensitivity; GWAS; Genetics; Epistasis; Systems biology</p></sec></sec></sec><sec id="Sec154"><title>P142 Genetic predisposition of cold medicine related SJS/TEN with severe ocular complications</title><sec id="Sec155"><title>Mayumi Ueta<sup>1</sup>, Hiromi Sawai<sup>2</sup>, Chie Sotozono<sup>3</sup>, Katushi Tokunaga<sup>2</sup>, Shigeru Kinoshita<sup>1</sup></title><sec id="Sec156"><title><sup>1</sup>Department of Frontier Medical Science and Technology for Ophthalmology, Kyoto Prefectural University of Medicine, Kyoto, Japan; <sup>2</sup>Department of Human Genetics, Graduate School of Medicine, The University of Tokyo, Tokyo, Japan; <sup>3</sup>Department of Ophthalmology, Kyoto Prefectural University of Medicine, Kyoto, Japan</title><p><bold>Correspondence:</bold> Mayumi Ueta</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P142</p><p><bold>Background:</bold> Stevens–Johnson syndrome (SJS) is an acute inflammatory vesiculobullous reaction of the skin and mucosa such as the ocular surface, oral cavity, and genitals. In patients with extensive skin detachment and a poor prognosis, the condition is called toxic epidermal necrolysis (TEN). Severe ocular complications (SOC) appear in about 40 % of SJS/TEN patients diagnosed by dermatologists. Among SJS- and TEN patients, especially those with SJS/TEN with SOC, cold medicines (CM) including multi-ingredient cold medications and non-steroidal anti-inflammatory drugs were the main causative drugs. We reported that in the Japanese, CM-SJS/TEN with SOC was strongly associated with <italic>HLA</italic>-<italic>A*02:06</italic> and significantly associated with <italic>HLA</italic>-<italic>B*44:03</italic>; in Indian and Brazilian caucasian populations it was associated with <italic>HLA</italic>-<italic>B*44:03,</italic> and in Koreans with <italic>HLA</italic>-<italic>A*02:06</italic>. In our 1st genome-wide association study, we analyzed our SJS/TEN with SOC patients using the Affymetrix GeneChip Mapping 500 K array set, and found an association between prostaglandin E receptor 3 (<italic>PTGER3</italic>) and SJS/TEN with SOC, and subsequently found that this association was stronger in patients with CM-SJS/TEN with SOC than in patients with all SJS/TEN with SOC.

cutaneous adverse drug reactions (SCARs). HLA-B1502 is strongly associated with the development of Stevens Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) to carbamazepine (CBZ) in Southeast Asian populations where the allele is prevalent. On the other hand, HLA-A3101 has been found to be a risk factor for (CBZ)-induced drug reaction with eosinophilia and systemic symptoms (DRESS) in European and Asian patients. HLA-A3101 has been weakly associated to CBZ-induced SJS/TEN in Europeans, and no association has been found with other aromatic antiepileptic drugs (AEDs). No HLA-I alleles have been definitely associated with lamotrigine (LTG)- or phenytoine (PHE)-induced SCARs in Europeans</p><p><bold>Materials and methods:</bold> To explore the association of HLA-I allele frequencies with SCARs to AEDs in our population, 12 patients with DRESS and 14 cases with SJS/TEN included in the Spanish registry PIEL<italic>enREd</italic> were studied. Six cases were related to LTG (3 SJS/TEN; 3 DRESS), 6 were related to CBZ (2 SJS/TEN; 4 DRESS), and 14 cases were induced by PHE (9 SJS/TEN; 5 DRESS). DNA was prepared from total blood and four digits HLA typing was performed. The frequencies of HLA-I alleles in patients with LTG-induced SCARs were compared with frequencies in patients within the other groups, and with previously published HLA-I frequencies in 253 Spanish individuals (Balas et al. Tissue Antigens, 2010).</p><p><bold>Results:</bold> HLA-B3801 allele was present in all three cases of LTG-induced SJS/TEN suggesting a strong association (OR 37.92; 95 % CI 5.4–269.53; p < 0.0001). Only 2 out of 9 SJS/TEN cases induced by PHE were carriers of HLA-B3801 (OR 4.74; 95 % CI 0.67–25.12; p = 0.09). None of the 12 DRESS cases analyzed were carriers of HLA-B3801. On the other hand, the 3 LTG-induced DRESS patients were carriers of HLA-A2402 showing a significant association as compared to the control sample (OR 5.25; 95 % CI 1.0–24.75; p = 0.04). HLA-A2402 was found in 3 out of 5 cases of PHE-induced DRESS (OR 4.5; 95 % CI 0.88–20.27; p = 0.054) and was absent in all CBZ cases and in SJS/TEN cases to PHE.</p><p><bold>Conclusions:</bold> Our results suggest that HLA-B3801 may be a risk factor for LTG-induced SJS/TEN, in agreement with previous data (Lonjou et al. Pharmacogenetics and Genomics 2008). On the other hand HLA-A2402 might be related with LTG-induced DRESS or exantematic reactions, as recently published in the Norwegian population (Shirzadi et al.

Class II HLA-DRA variants have been associated with immediate allergic reactions to beta-lactams and the HLA-DRB1*07:01 allele has been associated with IgE-mediated reactions to asparagine. Up to 27 % of women exposed to 6 or more cycles of carboplatin present with immediate HSR and 50 % of these reactions are anaphylactic. BRCA1/2 mutations have been found to be more common among patients who develop immediate reactions to carboplatin and these reactions, including anaphylaxis, have been successfully addressed by rapid drug desensitization (RDD). We sought to evaluate the HLA profile of patients who presented an initial carboplatin-induced severe hypersensitivity reaction including anaphylaxis, had a positive skin test and were treated with the BWH rapid drug desensitization 3–4 bags protocol.</p><p><bold>Materials and methods:</bold> HLA ABC DR DQ DP typing was conducted for a cohort of Caucasian ovarian cancer patients (n = 11) with a history of grade 2 or 3 type I HSR to carboplatin undergoing RDD and a control group of Caucasian ovarian cancer patients treated with carboplatin, who tolerated 8 or more cycles (n = 12). Allele carriage amongst cases and controls was compared using Fisher’s exact test. The <italic>Haploblocks</italic> program was used to generate cobygram visuals of HLA co-carriage.</p><p><bold>Results:</bold> Among allergic patients, 36 % (4/11) had grade 2 and 64 % (7/11) grade 3 initial HSR. All successfully tolerated the RDD and were able to complete their treatment plans. We found that the HLA-DRB1*15:01 allele was more prevalent among allergic patients (5/11, 45 %) than among the control group (1/12, 8.3 %) (p = 0.06). Cobygram analysis suggests that the HLA class II association may extend to the DQA1*01:02-DQB1*06:02-DRB1*15:01 haplotype (Fig. <xref rid="Fig6" ref-type="fig">6</xref>).<fig id="Fig6"><label>Fig. 6</label><caption><p>Overrepresentation of DQA1*01:02-DQB1*06:02-DRB1*15:01 haplotype in the allergic group</p></caption><graphic xlink:href="13601_2016_122_Fig6_HTML" id="MO7"></graphic></fig></p><p><bold>Conclusions:</bold> In this Caucasian cohort of ovarian cancer patients, a specific HLA class II allele, DRB1*15:01, was suggested to be associated with immediate hypersensitivity to carboplatin.

In case of remote history of immediate reaction to beta-lactam, if tests are negative, a provocation test with the culprit drug is necessary and should be followed by repetition of skin tests.</p><p><bold>Report:</bold> We report the case of a woman aged 61 years who experienced a systemic reaction (urticaria, vomit, diarrhea, fatigue) 15 min after intake of amoxicillin/clavulanic acid. Four months later, she underwent a visit in our Allergy Unit and serological and skin tests were scheduled.</p><p>Serological specific Ig-E against penicilloyl G, penicilloyl V, ampicillin, amoxicillin, cefaclor as well as skin tests gave negative result. They were performed respectively 5 and 9 months after the reaction. A drug provocation test (DPT) with amoxicillin was then performed and was considered positive for the occurrence of generalized pruritus 20 min after the intake of the last dose (cumulative dose 875 mg). Skin tests were repeated with positive results to both amoxicillin and ampicillin, at the concentration of 1 and 20 mg/ml, respectively.</p><p><bold>How this report contributes to current knowledge:</bold> Specific Ig-E levels against beta-lactams decrease after immediate-type reactions. Guidelines recommend to perform allergological work up within 6–12 months. Our case shows how this period might be too long and false negative tests can occur even if performed within one year. DPT should always follow negative skin tests to obtain a correct diagnosis.</p><p><bold>Consent:</bold> Written informed consent was obtained from the patient for publication of this abstract and any accompanying images.</p></sec></sec></sec><sec id="Sec173"><title>P148 Drug provocation tests in suspected opioid allergy</title><sec id="Sec174"><title>Kok Loong Ue, Krzysztof Rutkowski</title><sec id="Sec175"><title>Department of Allergy, Guy’s and St Thomas’ NHS Foundation Trust, London, United Kingdom</title><p><bold>Correspondence:</bold> Kok Loong Ue</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P148</p><p><bold>Background:</bold> There are no good epidemiological data regarding opioid allergy (OA). Many side effects can occur with this group of drugs. These are often misinterpreted as an IgE-mediated OA. As a consequence, many patients receive an unsubstantiated diagnosis of OA and avoid opioid unnecessarily. Diagnosis of OA can be challenging as skin tests (ST) and opioid-specific IgE have a poor predictive value. Drug provocation tests (DPT) remain the gold standard for the diagnosis of OA. However, there are almost no studies of opioid DPT and no validated opioid DPT protocols.</p><p><bold>Materials and methods:</bold> 30 suspected cases of OA (12 morphine, 18 codeine) were studied using detailed history and oral DPT. Opioid ST and specific IgE were not performed. Standardised local protocols were used. For morphine: 2, 3, and 5 mg morphine sulphate oral solution (10 mg/5 ml) was administered at 30 min interval with 120 min monitoring. For codeine: 10, 20 and 30 mg codeine phosphate syrup (25 mg/5 ml) was administered at 30 min interval with 60 min of monitoring. All DPT were performed on a specialist allergy unit.</p><p><bold>Results:</bold> 25 females and 5 males (median age of 46.5) experienced various symptoms reported as OA. Opioids were prescribed mainly for analgesia. 20 patients (67 %) had cutaneous symptoms: angioedema: 5, urticaria: 4, angioedema and urticaria: 2, unspecified rash: 5, angioedema, unspecified rash and pruritus: 3, angioedema and unspecified rash: one. 11 patients (37 %) experienced symptoms suggestive of anaphylaxis: dyspnoea, tachycardia, hypotension, dizziness and collapse. 2 of these (18 %) experienced cutaneous symptoms too. Other non-specific symptoms included nausea: 2, paraesthesia: 2, tremor: 1, anxiety: 1. DPT were negative in 23 patients (77 %). 6 patients (20 %) had symptoms of intolerance: pruritus, nausea, dizziness, tremor to morphine (2) and codeine (4). Only 3 % of DPT were positive: 1 patient experienced angioedema with codeine.</p><p><bold>Conclusions:</bold> DPT-confirmed OA appears to be very rare (3 %). Most symptoms misinterpreted as OA could be due to a dose-dependent mast cell degranulation, genetic polymorphism of CYP2D6 gene or the underlying acute illness. Morphine and codeine DPT are a safe and reliable diagnostic tool. Our ongoing multi-centre study will endeavour to validate this approach in a larger cohort of suspected OA patients (including other opioids) and produce standardised DPT protocols to improve the diagnosis of OA in Europe and worldwide.</p><p><bold>Keywords:</bold> Anaphylaxis; Codeine; Drug provocation test; Morphine; Opiod allergy</p></sec></sec></sec><sec id="Sec176"><title>P149 Improvement to the specific IgE cut-off in the assess of β-lactamic allergy</title><sec id="Sec177"><title>Victor Soriano Gomis, Jorge Frances Ferre, Angel Esteban Rodriguez, Vicente Cantó Reig, Javier Fernandez Sanchez</title><sec id="Sec178"><title>Universitary General Hospital of Alicante, Alicante, Spain</title><p><bold>Correspondence:</bold> Victor Soriano Gomis</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P149</p><p><bold>Background:</bold> Specific IgE against β-lactams by CAP FEIA system (Thermo Scientific<sup>®</sup>) used to use the cut-off of 0.35 kU/l, but now we can get a detection limit of the assay of 0.10 kU/l.

The gelatin infusion was stopped and treatment with epinephrine, norepinephrine, promethazine, hydrocortisone, and saline fluid expansion installed. Serum tryptase was transiently increased (95.7 ng/dl 1h30 after the onset of the reaction vs 6.0 ng/dl > 24 h after the event).

To this avail we synthesized a generation two BAPAD dendrimer using cystamine as core. Then, the free amine groups on the surface of the dendrimer were functionalized with an amoxiciloyl group (AXO). The fluorescent DeAn has been fully characterized by NMR and MS techniques, and their fluorescent properties well established in aqueous biological media using confocal microscopy. The fluorescent dendron (De) without the haptenic moieties at the periphery has been also obtained and fully characterized as a control assay. The fluorescent DeAn and De was used in dissolution and supported in solid surface (cellulose disk). The solid conjugates were immunologically evaluated by RAST inhibition using sera from 7 patients allergic to amoxicillin.

The RAST inhibition studies of solid supported DeAn showed a higher RAST inhibitions values for allergic patients compare with negatives controls. This value was also compared with solid surfaces conjugated with PLL-AXO showing similar results.</p><p><bold>Conclusions:</bold> These dendrimeric structures assayed in RAST inhibition studies letting us check that inhibition occurred, so recognition existed between IgE of patients allergic to amoxicillin and DeAn structures.</p><p><bold>Keywords:</bold> Confocal microscopy; Dendritic cell; Maturation</p></sec></sec></sec><sec id="Sec188"><title>P153 Positive skin test or positive specific IgE to penicillin does not predict penicillin allergy</title><sec id="Sec189"><title>Line K.

Diagnosis of anaphylaxis during anaesthesia mainly relies on skin testing, since assays for the detection of IgE-antibodies are not available and provocation tests are not feasible for most of the involved drugs. Neuromuscular blocking agents (NMBAs) are recognized as the most prevalent elicitors of PDH, however, skin tests with NMBAs might result in false-positive results due to unspecific, non-IgE-mediated release of histamine.</p><p><bold>Materials and methods:</bold> To further investigate this subject, we evaluated the potential of NMBAs eliciting positive results in individuals with known NMBA-tolerance in both skin prick (SPT) and intracutaneous tests (ICT) and compared these with the reactivity in basophil activation tests (BAT).

Elzagallaai</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P155</p><p><bold>Background:</bold> β-lactam antibiotics (BLAs) are the drugs most associated with immune-mediated hypersensitivity reactions (drug allergy). They can elicit all types of allergic reactions i.e., types I, II, III and IV. Although the immediate IgE-mediated reaction has been well studied, the pathophysiology of non-immediate hypersensitivity reactions is not well understood. Cross-reactions among BLAs with different side chains are variable. The diagnosis and prediction of BLAs-induced allergic reactions is challenging and based mostly on clinical history. The lymphocyte toxicity assay (LTA) and the in vitro platelet toxicity assay (<italic>i</italic>PTA) are in vitro tests with a potantial value for diagnosis and prediction of drug allergy. Their value in diagnosis of reactions to BLAs, however, is still unknown. This work is an attempt to evaluate the performance of in vitro toxicity testing for diagnosis of different types of allergy to BLAs and to investigate the their different underlying pathophysiology.</p><p><bold>Materials and methods:</bold> One hundred and seventy individuals (85 drug allergy-suspected patients and 85 healthy volunteers) were included in this study. Patients were identified from clinical records and included using a rigorous internationally recognized inclusion criteria based on their clinical presentation and available diagnostic investigations (i.e., skin testing and RAST). The LTA and <italic>i</italic>PTA tests were performed after resolution of the reaction symptoms. Data was expressed as percentage of cell death compared to control (vihicle without the drug) after incubation with the suspected drug in presence of rat microsomes (MICs).</p><p><bold>Results:</bold> Patients were grouped according to their exhibited symptoms into 3 groups constituted of 8 patients type I, 28 patients type III and 49 patients type IV. Patients with type IV reactions exhibited higher degrees of cell death than the other 2 groups (p < 0.05) with type I patients exhibiting the lowest degree of cell death among all groups.</p><p><bold>Conclusions:</bold> Using the in vitro toxicity testing (LTA and <italic>i</italic>PTA) we were able to identify patients susceptible to develop allergy to BLAs. In addition, cells isolated from patients with different types of reactions exhibit variable degrees of cell death, which indicate possible distinct pathophysiological mechanisms.

Whilst receiving escalating antimicrobial treatment, for bacteraemia and fevers >38.3 °C, he developed a blistering rash involving >30 % of body surface area (BSA) associated with a positive Nikolsky sign, consistent with TEN. Multiple antimicrobials were administered prior to onset of TEN, four of which—vancomycin, meropenem, linezolid and teicoplanin—were temporally associated with the onset of TEN.</p><p><bold>How this report contributes to current knowledge:</bold> We sought to use cellular assays, IFN-γ ELISpot and flow cytometry, to identify the causative agent of TEN in a patient receiving multiple antibiotics. Following informed consent, patient whole blood was collected on day 4 post onset of TEN. PBMCs were extracted and cryopreserved. HLA ABC DR DQ DP typing was performed and the PBMCs were used for ex vivo ELISpot testing. PBMCs were also incubated with candidate drugs for 18–20 h at 37 °C in 5 % CO<sub>2</sub> and assessed by flow cytometry for upregulation of the T cell activation marker CD137.</p><p>Patient HLA was HLA-A*01:01 and 02:02, HLA-B*37:01 and 41:01, HLA-C*10:01 and 17:01, HLA-DPB1*10:01, HLA-DQA1*01:01 and 02:01, HLA-DQB1*02:02 and 05:01, HLA-DRB1*07:01 and 10:01. Positive ELISpot responses were reproducibly produced only to the glycopeptide antibiotic teicoplanin, with up to 300 SFU/million cells. ELISpot data were confirmed by flow cytometry analysis, where only teicoplanin induced up-regulation of the activation marker CD137 (0.3 % of total CD8+ T-cells).

While DLST is widely used as in vitro diagnostic tool, its sensitivity and specificity are unsatisfactory. Determination of antigen-specific IFN-γ production by enzyme-linked immunospot assay (conventional IFNγ-ELISpot) is well-established diagnostic method for tuberculosis infection, and recent reports suggested that drug-induced conventional IFNγ-ELISpot is useful for identifying the culprit drug of cADR cases. The aim of this study was to establish a novel diagnostic method for identifying the culprit drug in cADR patients through the efficient detection of the drug-specific IFN-γ production by IFNγ-ELISpot.</p><p><bold>Materials and methods:</bold> Ten cases of cADR caused by clinically convincing culprit drugs were enrolled in this study. Peripheral blood mononuclear cells (PBMCs) from all 10 patients were used for both DLST and drug-induced conventional IFNγ-ELISpot. In addition, drug-induced IFNγ-ELISpot was also performed by using PBMCs which were non-specifically stimulated with monoclonal antibodies for 7 days before exposing culprit drugs (modified IFNγ-ELISpot) in all cases.</p><p><bold>Results:</bold> Drug-induced IFN-γ production was detected by modified IFNγ-ELISpot in 5 patients of which DLST and conventional IFNγ-ELISpot were both negative.

Patch test and lymphocyte stimulation test (LST; also known as DLST in Japan) are frequently used for this purpose, but their positivity ratios are not sufficiently high.

Moreover, to see the drug-induced T-cell proliferation, the expanded T cells were labeled with CFSE and cultured with drugs and X-ray-irradiated PBMCs for a week, and the proliferation was assessed by flow cytometry.

For several drugs including, abacavir and carbamazepine, two components of this trimolecular complex have been defined. For abacavir hypersensitivity reaction (HSR) the associated MHC is HLA-B*57:01 and for carbamazepine induced Stevens–Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), the associated MHC is HLA-B*15:02. In the former instance the association of drug with MHC has been further defined with the successful resolution of the crystal structure of the abacavir complexed to HLA B57:01.</p><p>To fully understand T cell mediated hypersensitivity reactions the nature of the T cells involved and ultimately the mechanism by which the TCR interacts with MHC plus drug must be elucidated.

PBMC samples with confirmed T-cell reactivity (ELISpot) were treated with drug for 18–20 h. Upregulation of the activation marker CD137 was used to sort drug reactive CD8+ or CD4+ T cells.

Causality assessment is often a problem in polymedicated patients. The probability algorithm of the Spanish Pharmacovigilance System (Capellá and Laporte 1993) establishes different categories of causality after scoring of chronology, bibliography, drug withdrawal, re-exposure, and alternative causes (unlikely: <0, conditional: 1–3; possible 4–5, probable: 6–7, definite: >8). LTT has been used as a tool to determine the causality of cADR. LTT specificity and sensitivity are difficult to ascertain as the gold standard (re-challenge) is not acceptable in severe cases.</p><p><bold>Materials and methods:</bold> A total of 34 LTT assays were performed with suspected drugs in 15 DRESS cases included in the Spanish registry PIEL<italic>enRED</italic>. Results were considered positive if stimulation indexes (SI) were ≥2, except for betalactam antibiotics (SI ≥ 3) or iodinated contrast media (SI ≥ 4). The Spanish Pharmacovigilance System algorithm (SPA) was applied and suspected drugs were divided into two categories: unrelated (SPA score ≤3) and related (SPA score ≥4).</p><p><bold>Results:</bold> Positive LTT results were obtained in all patients. In 19 out of 23 positive LTT assays the drugs were related to the adverse reaction (SPA score ≥4). Ten out of the 11 drugs that tested negative were predicted to be unrelated to the adverse reaction (SPA score ≤3). A contingency table was built (Table <xref rid="Tab9" ref-type="table">9</xref>). Fisher’s exact test was used to analyze the data. There was a significant agreement between the two methods (OR 47.5; 95 % CI 3.9–1342.94). If the pharmacovigilance algorithm was considered as gold standard, 95 % sensitivity and 71 % specificity were obtained for LTT assays, with a positive predictive value (PPV) = 82 % and negative predictive value (NPV) = 90 % (p < 0.001). On the other hand, if LTT was considered as gold standard, 82 % sensitivity and 90 % specificity was obtained for the SPA, with a PPV = 90 % and NPV = 70 % (p < 0.001).<table-wrap id="Tab9"><label>Table 9</label><caption><p>Drug causality data in DRESS patients</p></caption><table frame="hsides" rules="groups"><thead><tr><th align="left" rowspan="2"></th><th align="left" colspan="2">Pharmacovigilance algorithm (SPA) results</th><th align="left" rowspan="2">Total</th></tr><tr><th align="left">Related drug (SPA ≥ 4)</th><th align="left">Unrelated drug (SPA ≤ 3)</th></tr></thead><tbody><tr><td align="left">Positive LTT</td><td char="." align="char">19</td><td char="." align="char">4</td><td char="." align="char">23</td></tr><tr><td align="left">Negative LTT</td><td char="." align="char">1</td><td char="." align="char">10</td><td char="." align="char">11</td></tr><tr><td align="left">Total</td><td char="." align="char">20</td><td char="." align="char">14</td><td char="." align="char">34</td></tr></tbody></table></table-wrap></p><p><bold>Conclusions:</bold> Although this is a small case series, the results indicate that LTT is a sensitive tool for causality assessment in DRESS.

T cells were cloned from both blood and inflamed skin of hypersensitive patients and naïve T cells from healthy donors were primed to piperacillin using dendritic cells.</p><p><bold>Results:</bold> Drug-specific clones were generated from both blood (n = 570, 84 % CD4) and skin (n = 96, 83 % CD4) from patients hypersensitive to piperacillin. All clones secreted high levels of IFNγ and IL13 following drug stimulation. Interleukin-22, perforin and granzyme B were also secreted by over 50 % of clones. In contrast, IL17A secretion was not detected. Naïve T cells primed to piperacillin using autologous dendritic cells, proliferated in the presence of drug (p = 0.001, SI > 2) and had a similar pattern of cytokine secretion to clones generated from hypersensitive patients. Significant differences in chemokine receptor expression were observed between the different populations of T cell clones. CLA, CXCR6 and CCR1 expression was higher on piperacillin-specific skin-derived clones when compared to non piperacillin-specific skin-derived clones (p = 0.01). CCR2, CCR4, CXCR1 and E-cadherin were higher on skin-specific clones when compared to blood-specific clones (p = 0.01). Piperacillin-specific clones isolated from blood and skin of hypersensitive patients, as well as piperacillin-specific T cells from healthy donors migrated in the presence of chemokines specific to their respective cell surface receptors, with migration to CCR4 and CCR10 most prevalent. Finally, regulation of the cytokine secretion through modulation of nuclear receptor signalling was studied. Inhibition of the aryl hydrocarbon receptor during naïve T cell priming abrogated the drug-specific cytokine response.</p><p><bold>Conclusions:</bold> Our data describe a subset of piperacillin-specific T-cells that secrete IL-22, IFNγ, perforin and granzyme B, but not IL-17, in response to antigen challenge. Taken together this suggests that IL-22 is important in the progression of β-lactam hypersensitivity.</p></sec></sec></sec><sec id="Sec219"><title>P164 Vancomycin-specific T cell responses and teicoplanin cross-reactivity</title><sec id="Sec220"><title>Wei Yann Haw, Marta E.

Hypersensitivity responses to vancomycin are well recognised but the risk of cross-reactivity with teicoplanin is unclear. Our study aims to examine the role of T cell responses in vancomycin hypersensitivity reactions and explore the potential for cross-reactivity between vancomycin and teicoplanin.</p><p><bold>Materials and methods:</bold> Our cohort comprised of vancomycin exposed allergics who had suffered delayed skin drug hypersensitivity reactions n = 17; non-allergic previously vancomycin exposed controls n = 5; and vancomycin naïve controls n = 12. We tested ex vivo drug induced lymphocyte proliferation and cytokine release. Vancomycin-specific T cell lines were grown to test for teicoplanin cross-reactivity.</p><p><bold>Results:</bold> In our cohort of vancomycin allergics, vancomycin hypersensitivity reaction patterns were drug exanthems (47.1 %), DRESS (29.4 %), or SJS/TEN (23.5 %). Circulating IFN-γ vancomycin-specific T cells were identified at higher frequency than naïve controls: (IFN-γ p < 0.0001; SI p = 0.042). Interestingly, detectable frequencies in vancomycin exposed controls were higher than naïve controls (p < 0.0001; SI p = 0.12) suggesting that low frequency responses were the result of vancomycin priming even in the context of a non-allergic individual. This was confirmed by the expansion of short term T cell lines in vancomycin exposed controls (IFN-γ p = 0.008; SI p = 0.016). Cross-reactivity against teicoplanin was found to be minimal (42.7 × 10<sup>−4</sup> % IFN-γ and SI 1.0 in vancomycin-specific T-cell lines compared to 48 × 10<sup>−4</sup> % IFN-γ and SI 1.3 in non-vancomycin-specific T-cells lines).</p><p><bold>Conclusions:</bold> Circulating vancomycin specific-T cell frequencies were found to be higher in vancomycin allergics than vancomycin exposed controls, which in turn were higher than naïve controls. Using vancomycin-specific T cell lines we did not see any evidence of teicoplanin cross-reactivity despite the similar molecular structures of the two drugs. We also showed that low-level of vancomycin-specific responses identified ex vivo in exposed controls were able to efficiently expand on short term culture, confirming that they were genuine vancomycin-specific T cells. This suggests both immune predisposition and potentially adaptive regulation may be important in regulating the development of hypersensitivity reactions to vancomycin.</p><p><bold>Keywords:</bold> Drug hypersensitivity reactions; T cell; Vancomycin; In-vitro diagnostic tests</p></sec></sec></sec></sec><sec id="Sec222"><title>Poster Walk 19: BAT and biomarkers (P165–P173)</title><sec id="Sec223"><title>P165 A combination of early biomarkers useful for the prediction of severe ADRs</title><sec id="Sec224"><title>Yumi Aoyama<sup>1</sup>, Tetsuo Shiohara<sup>2</sup></title><sec id="Sec225"><title><sup>1</sup>Kawasaki Hospital Kawasaki Medical School, Okayama, Japan; <sup>2</sup>Kyorin University School of Medicine, Tokyo, Japan</title><p><bold>Correspondence:</bold> Yumi Aoyama</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P165</p><p>The published version of this abstract can be found at [1].</p><p><bold>Reference</bold><list list-type="order"><list-item><p>Shiohara T, Mizukawa Y, Yumi A.

The drugs used for desensitization in the order of the most frequent to the least were as follows: parenteral or per oral chemotherapeutics, aspirin, corticosteroids, storage enzymes, iron salts and anti-thyroidal drugs. Skin prick tests were positive in 5 patients with parenteral chemotherapeutics, 2 patients with iron salts, 2 patients with storage enzymes and in one patient with methylprednisolone. The baseline cytokine levels were not statistically different between the three groups. The desensitization was not successful in 4 of the patients and because of this insufficient patient number their cytokine levels were not further analyzed. The IL-10 levels after the successful desensitization procedure in 22 patients significantly increased when compared to their baseline levels (p: 0.006). The rise in IL-10 levels were greater in chemotherapeutic desensitizations than the desensitizations with other drugs (p: 0.005) whereas the other three cytokines did not significantly change.</p><p><bold>Conclusions:</bold> Successful desensitization can be related with increase in IL-10.

Most publications describe isolated cases and limited data are available about the value of skin tests. Therefore, the diagnostic approach is the drug provocation test (DPT), which is not risk free, especially for severe reactions. The aim of the study was to assess the value of the basophil activation test (BAT) for the diagnosis of immediate allergic reactions to PPI.</p><p><bold>Materials and methods:</bold> We evaluated 49 patients with immediate allergic reactions to PPI. Twenty-two subjects with good tolerance to PPI were included as controls. Patients with anaphylaxis or shock were diagnosed by clinical history, once other possible causes were ruled out, and those with urticaria-angioedema or pruritus, by DPT. BAT with omeprazole and pantoprazole at 3 different concentrations (2, 0.2 and 0.02 mg/ml) using CD193 (CCR3) and CD203c for basophil selection and CD63 as activation marker, was performed in all patients and controls.</p><p><bold>Results:</bold> The PPIs involved were omeprazole (N = 43), pantoprazole (N = 1) lansoprazole (N = 2) and esomeprazole (N = 2), one patient had two reactions, one with omeprazole and other one with pantoprazole. A total of 20 cases (40.81 %) reported anaphylaxis, 12 (24.48 %) anaphylactic shock, 13 (26.53 %) urticaria-angioedema, and 4 (8.16 %) pruritus. BAT was positive in 36 cases (73.46 %): 14 to omeprazole and pantoprazole (28.5 %), 19 to omeprazole (38.7 %) and 3 to pantoprazole (6 %).

Most reactions induced by FQ were immediate. For the in vitro diagnosis only the basophil activation test (BAT) has shown to be useful although with suboptimal sensitivity. The aim of our study was to analyze the BAT to FQ using two different activations markers, CD63 and CD203c, in the evaluation of patients with immediate allergic reactions to these drugs.</p><p><bold>Materials and methods:</bold> Seventeen patients with confirmed immediate allergic reactions to FQ (6 to Ciprofloxacin and 11 to Moxifloxacin) were included in the study. Eighteen controls with tolerance to FQ were also included. BAT was performed with Moxifloxacin and Ciprofloxacin at 2 and 0.2 mg/ml using CD203c and CD63 as activation markers. Positive results were considered when SI > 3 to at least one of the concentrations used in the test.</p><p><bold>Results:</bold> Data indicated that although both Ciprofloxacin and Moxifloxacin are able to induce both activation marker expression (CD63 and CD203c), there is a predominance in the expression of each one depending on the drug included in the test. Thus Ciprofloxacin was able to mainly increase the expression of CD63 (40 %, p = 0.0053) whereas Moxifloxacin mainly increase the expression of CD203c (10 %). In addition, analyzing the expression of both markers in basophils from Moxifloxacin allergic patients stimulated with the culprit drug, we found a higher expression of CD203c in patients suffering anaphylactic shock (7 %), whereas was CD63 the marker that showed a higher up-regulation in patients with anaphylaxis (17 %). When we analyzed the sensitivity and specificity of the test using these activation markers we can see that the best results were observed using the culprit drug and CD203c as activation marker for Moxifloxacin (S = 36.4 % and E = 94.4 %) and CD63 for Ciprofloxacin (S = 83.3 % and E = 88.9 %).</p><p><bold>Conclusions:</bold> The BAT must be performed using the culprit drug and CD203c for Moxifloxacin or CD63 for Ciprofloxacin as activation marker to diagnose Quinolone Allergy. Although this differential expression of both activation markers seems to be also related with the culprit drug and clinical entity. Using this criteria and a cut-off of 3, we have obtained a better sensitivity for Ciprofloxacin.</p></sec></sec></sec><sec id="Sec244"><title>P172 The importance of basophil activation test in anaphylaxis due to celecoxib</title><sec id="Sec245"><title>Amalia Bernad Alonso, Carmen D’Amelio Garófalo, Olga Vega Matute, Marta Ferrer Puga, María José Goikoetxea Lapresa, Roselle Catherine Yu Madamba, Gabriel Gastaminza Lasarte</title><sec id="Sec246"><title>Clínica Universidad de Navarra, Pamplona, Spain</title><p><bold>Correspondence:</bold> Amalia Bernad Alonso</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P172</p><p><bold>Background:</bold> Celecoxib, is a specific COX-2 inhibitor which is an alternative treatment for patients with intolerance to NSAIDs.</p><p><bold>Report:</bold> We present two cases of anaphylaxis due to Celecoxib. The first is a 57 year old male who was taking Celecoxib as an alternative medication for sciatic pain since he had poor gastric tolerance with NSAIDs. He had a history of idiopathic recurrent urticaria. He had an episode of anaphylactic shock 30 min after taking 1 tablet of Celecoxib which prompted him to sought consult at the emergency room wherein he was administered with Epinephrine IM. On follow up after 1 month, prick test with Celecoxib revealed negative. Because the suspicion that the reaction was caused by allergy to Anisakis, a challenge test with Celecoxib was done that resulted positive, and epinephrine was administered. Basophil activation test was positive with Celecoxib and negative to Parecoxib. Two months later, he presented with hives 2 h after taking 750 mg of acetylsalicylic acid (ASA). Tolerance test with Meloxicam and Nabumetone were performed which the patient tolerated well.</p><p>The second case is a 58 year old male who had an episode of anaphylaxis 3 h after taking Celecoxib for headache. Tryptase was elevated, 19.9 μg/l. A month earlier, he had generalized itching after taking one tablet of celecoxib. He took Metamizol previously which he tolerated well. No history of atopy nor allergy to medications. Skin tests to NSAIDs were negative. Basophil activation test was positive with celecoxib and negative to ASA, Metamizole, Paracetamol, Parecoxib and Dexketoprofen. He underwent challenge test with Aspirin with positive result. Both patients were diagnosed with intolerance to NSAIDs and anaphylaxis secondary to Celecoxib.</p><p><bold>How this report contributes to current knowledge:</bold> Anaphylaxis due to Celecoxib is considered a rare entity as patients with intolerance to NSAIDs usually tolerate Celecoxib and other COX-2 inhibitors. The positive result in the basophil activation test together with a compatible clinical history makes us hypothesize that these are cases of a selective hypersensitivity to Celecoxib, instead of the fact that both patients were finally NSAIDs intolerant. Hence, BAT can be useful for the diagnosis, given the low sensitivity of skin tests.</p><p><bold>Consent:</bold> Written informed consent was obtained from the patient for publication of this abstract and any accompanying images.</p></sec></sec></sec><sec id="Sec247"><title>P173 The role of basophil activation test in the diagnosis of immediate type drug hypersensitivity to betalactam antibiotics</title><sec id="Sec248"><title>Antonia Thinnes, Hans F.

Although the association of specific HLA alleles with hypersensitivity is important, for most drugs, the majority of individuals who are positive for an HLA risk allele do not develop a reaction. Thus, predisposition is likely mediated by other parameters, which may include T-cell co-inhibitory pathways. As polymorphisms in co-inhibitory pathways are associated with dysregulated immune responses, we investigated the role of these pathways during drug (SMX-NO)-specific T-cell responses. Programmed death-1 (PD-1) and cytotoxic T-lymphocyte associated protein 4 (CTLA4) are considered to be key immune checkpoints, and TIM-3 is of current interest due to its reported upregulation alongside PD-1.</p><p><bold>Materials and methods:</bold> Naïve and memory T-cells from healthy donors were incubated for 8 days with SMX-NO and dendritic cells ± PD-L1, CTLA4, TIM-3 blocking antibody. Antigen-reactivity was then assessed by T-cell cytokine secretion and proliferation. Cell phenotype was assessed by flow cytometry. T-cell clones were then generated from these cultures.</p><p><bold>Results:</bold> While blockade of PD-L1 or CTLA4 enhanced the activation of SMX-NO-primed naïve T-cells, only the blockade of CTLA4 enhanced the proliferative response of antigen-stimulated memory T-cells suggesting a greater regulatory role for CTLA4 during secondary T-cell responses. Blockade of TIM-3 had no effect on T-cell activation of either naïve or memory cells. While all receptors were upregulated on T-cells after antigen exposure, PD-1 was upregulated at earlier time points than CTLA4 and TIM-3 indicating a differential role for these receptors during early and late stage T-cell activation. High expression of individual co-inhibitory receptors has previously been associated with exhausted T-cells, while other studies indicate that these cells are highly functional. We found no correlation between the level of individual co-inhibitory receptor expression and the strength of T-cell activation in the T-cell clones.</p><p><bold>Conclusions:</bold> Drug-induced stimulation of naïve T-cells was significantly enhanced by blocking PD-L1 or CTLA4. However, the co-inhibitory pathways did not have a great effect on memory T-cell responses. Any differences in the control of the different T-cell co-inhibitory pathways may be important in determining whether a particular individual develops a hypersensitivity response to a drug.</p></sec></sec></sec><sec id="Sec254"><title>P175 Characterization of drug hapten-specific T cell responses in piperacillin hypersensitive patients</title><sec id="Sec255"><title>Zaid Al-Attar<sup>1</sup>, Fiazia Yaseen<sup>1</sup>, Xiaoli Meng<sup>1</sup>, Rozalind Jenkins<sup>1</sup>, Paul Whitaker<sup>2</sup>, Daniel Peckham<sup>2</sup>, Lee Faulkner<sup>1</sup>, John Farrel<sup>1</sup>, Kevin Park<sup>1</sup>, Dean Naisbitt<sup>1</sup></title><sec id="Sec256"><title><sup>1</sup>MRC Centre for Drug Safety Science, Dept Molecular & Clinical Pharmacology, University of Liverpool, Liverpool, United Kingdom; <sup>2</sup>Regional Adult Cystic Fibrosis Unit, St James’s Hospital, Leeds, United Kingdom</title><p><bold>Correspondence:</bold> Zaid Al-Attar</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P175</p><p><bold>Background:</bold> Piperacillin is a b-lactam frequently used to combat bacterial infections in patients with cystic fibrosis. However, its use is associated with high incidence of delayed-type hypersensitivity reactions. Previous studies have identified lymphocyte proliferative responses and cytokine secretion from PBMCs isolated from approximately 75 % of hypersensitive patients but not from tolerant controls. The drug forms a hapten that binds covalently to specific lysine residues on serum albumin (HSA).</p><p><bold>Aim</bold>: To generate a synthetic piperacillin-HSA conjugate and to quantify the level of modification at specific lysine residues. Furthermore, the activation of T-cells with free drug and the drug-protein conjugate was assessed.</p><p><bold>Materials and methods:</bold> Piperacillin was incubated with HSA at different molar ratios (10:1–250:1 drug:protein). Mass spectrometry was used to characterize modification at specific lysine residues. PBMCs from hypersensitive patients were cultured in the presence of parent drug and the piperacillin-HSA conjugate and T-cell clones generated by serial dilution. T cell clones were analysed for antigen-specific proliferative responses, cytokine release and TCR-Vb usage.</p><p><bold>Results:</bold> Cyclised and hydrolysed forms of piperacillin hapten were detected on over 10 lysine residues of HSA. Quantitative analysis revealed that 3–23 % of lysine 541 was modified with piperacillin haptens. Sixty CD4+ clones displayed reactivity against piperacillin-modified HSA but did not respond to free piperacillin or to other b-lactam HSA adducts. T cell activation was dependent on protein processing by antigen presenting cells and the level of modification with the piperacillin hapten, as low levels of modification failed to activate the clones. A further sixty CD4+ clones were responsive to free piperacillin and were not activated with the piperacillin-HSA conjugates. T-cell clones secreted a variety of molecules: IFN-γ (72 % of clones), IL5 (48 %), IL13 (37 %), perforin (48 %), granzyme B (26 %) and FasL (52 %) and showed a restricted expression of TCR-Vb9 (68 %).</p><p><bold>Conclusions:</bold> We have shown that drug hapten-responsive CD4+ T-cells with divergent antigen specificities circulate in hypersensitive patients.

Alternatively, PBMCs from 3 normal volunteers were cultured with telaprevir or VRT-127394 for 14 days. T-cells from both experimental procedures were cloned by serial dilution and repetitive mitogen stimulation. T-cell proliferative responses were assessed using [<sup>3</sup>H] thymidine incorporation and IFN-γ. Antigen-specific clones were phenotyped for CD4, CD8 and TCR Vb expression.</p><p><bold>Results:</bold> T-cell responses to telaprevir or VRT-127394 were not detected using the DC priming assay. However, 13 telaprevir-responsive T-cell clones were isolated from PBMC cultures from one volunteer. All 13 clones were stimulated to proliferate in the presence of telaprevir and its metabolite in a dose-dependent manner at a similar concentration range. Clones were not activated in the presence of antigen presenting cells pulsed with telaprevir for 1–16 h. 11 clones secreted IFN-γ when activated with telaprevir. 10 clones were CD4+ and 3 were CD8+. Clones expressed a restricted pattern of TCR-Vb which was dominated by Vb2 and Vb22.</p><p><bold>Conclusions:</bold> The data presented here shows that telaprevir-responsive T-cells were detected in healthy volunteers. CD4+ and CD8+ clones were activated with both telaprevir and the major metabolite VRT-127394. Future work will focus on assessing the nature of the T-cell response in hypersensitive patients.</p></sec></sec></sec><sec id="Sec260"><title>P177 Characterization of the T cell receptor signatures of drug-responsive T cells</title><sec id="Sec261"><title>Patricia Illing<sup>1</sup>, Nicole Mifsud<sup>1</sup>, Heidi Fettke<sup>1</sup>, Jeffrey Lai<sup>1</sup>, Rebecca Ho<sup>1</sup>, Patrick Kwan<sup>2</sup>, Anthony Purcell<sup>1</sup></title><sec id="Sec262"><title><sup>1</sup>Infection and Immunity Program, Monash Biomedicine Discovery Institute and Department of Biochemistry and Molecular Biology, Monash University, Clayton, Australia; <sup>2</sup>Royal Melbourne Hospital, University of Melbourne, Parkville, Australia</title><p><bold>Correspondence:</bold> Patricia Illing</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P177</p><p><bold>Background:</bold> The strongest associations reported to date between adverse drug reactions and specific Human Leukocyte Antigen (HLA) allotypes are between HLA-B*57:01 and abacavir hypersensitivity syndrome, HLA-B*58:01 and allopurinol hypersensitivities, and HLA-B*15:02 and carbamazepine induced Stevens–Johnson Syndrome/Toxic Epidermal Necrolysis. A lesser association also exists between HLA-A*31:01 and carbamazepine induced hypersensitivities. In this study we examined the diversity of the T cell response to these drugs (and metabolites) by characterising the T cell receptor (TCR) signatures of drug-responsive CD8+ T cells at a single cell level in patients and healthy donors. These studies were complimented by analyses of the diversity and perturbation of the HLA peptide repertoire following drug/metabolite exposure.</p><p><bold>Materials and methods:</bold> To characterise drug responsive TCR signatures, peripheral blood mononuclear cells were stimulated with the parent drug or metabolite in vitro and drug-responsive T cells characterized (phenotype and function) by flow cytometry. Single-cell flow cytometric sorting of drug-responsive CD8+ T cells was performed prior to a paired analysis of TCR alpha and beta chain variable regions using a novel multiplex nested RT-PCR methodology. To assess the influence of drugs/metabolites on peptide presentation by HLA molecules, HLA transfected B-Lymphoblastoid cell lines were grown to high density in the presence of the molecule of interest. 5–10 × 10<sup>8</sup> cells were harvested, the HLA molecules immunoaffinity purified, and the peptide/small molecule ligands dissociated and analysed using Liquid Chromatography Tandem Mass Spectrometry.</p><p><bold>Results:</bold> Our data demonstrated that the TCR signatures for abacavir-responsive CD8+ T cells were oligoclonal, correlating with previous reports of a large and diverse perturbation in HLA-B*57:01 peptide repertoire during abacavir exposure. Interestingly, whilst both carbamazepine and allopurinol hypersensitivities are postulated to occur via a direct interaction of the HLA-peptide-drug-TCR at the cell surface, and cause minimal change of the HLA peptide repertoire, their TCR usage profiles are divergent with carbamazepine being more restricted and allopurinol/oxypurinol exhibiting greater diversity.</p><p><bold>Conclusions:</bold> These data suggest a spectrum of diversity in the T cell response that may correlate with altered modes of drug presentation in HLA associated drug hypersensitivity.</p><p><bold>Keywords:</bold> Human leukocyte antigen; Carbamazepine; Allopurinol; Abacavir</p></sec></sec></sec><sec id="Sec263"><title>P178 Defining the signals between hepatocytes and immune cells in idiosyncratic drug-induced liver injury (DILI)</title><sec id="Sec264"><title>Monday O.

Furthermore, it is now apparent that drug-specific T-cells are activated in certain patients with DILI. The cross-talk signals between hepatocytes and the immune cells resident in the liver and circulation are likely to be critical in determining the outcome of drug exposure and development of immune-mediated DILI. However, tissue-specific immune signalling with respect to human DILI remains largely unexplored. Thus, the aim of this study was to profile the signals released by fresh human hepatocytes upon drug exposure and to characterise the impact of these molecules (cytokines and chemokines) on the phenotype and function of antigen presenting cells (APC).</p><p><bold>Materials and methods:</bold> Fresh human hepatocytes were exposed to three test compounds implicated in DILI (flucloxacillin, amoxicillin and isoniazid) and one reactive metabolite, nitroso-sulphamethoxazole (SMX-NO), and end-points of hepatocyte toxicity, cell viability and oxidative stress assessed.</p><p><bold>Results:</bold> HMGB1 and LDH release as well as ATP depletion occurred in a drug- and concentration-dependent manner. Furthermore, compound-specific activation of Nrf2 marker genes was observed with each of the test drugs. SMX-NO differentially induced the expression of NQO1, TXNRD1 and SRXN1 responsible for cytoprotection against chemically reactive metabolites. Also, the expression of AKR1B10, SRXN1 and LOC344887 were significantly increased by all the test compounds. Hepatocytes cultured with test drugs released a mixture of pro-inflammatory (IFN-γ, GM-CSF, IL-12p40, IL-12p70, IL-1β, TNF-α, TNF-β, IL-8 and MCP-1) and anti-inflammatory cytokines (IL-1RA, IL-10 and IL-13). Co-culture of APC with supernatant from drug treated hepatocytes resulted in a highly drug-dependent release of cytokines as well as significant changes in expression of MHC class II and CD86 on the cell surface of dendritic cells.</p><p><bold>Conclusions:</bold> In conclusion, our study begins to define the various factors that might be important in determining whether drug exposure in patients results in an immune response and tissue injury. We found that cross-talk signals were highly drug specific. The development of a liver/immune cell culture system will be an important step forward in advancing our understanding of the molecular mechanisms underlining the development of idiosyncratic DILI.</p><p><bold>Keywords:</bold> DILI; Hepatocytes; Idiosyncratic; Cytokines</p></sec></sec></sec><sec id="Sec266"><title>P179 Development of novel chemicals that do not bind to HLA-B*57:01 or activate CD8+ T-cells through modification of the 6-amino cyclopropyl group of abacavir</title><sec id="Sec267"><title>Paul Thomson, John Farrell, Mohammad Alhaidari, Neill Berry, Paul M.

It has been shown that abacavir can interact directly with the antigen binding cleft of HLA-B*57:01, altering its conformation and thereby causing an alteration of the peptides displayed on the cell surface. It has been hypothesized that these alternative self-peptide sequences trigger the CD8+ T-cell response in abacavir hypersensitive patients.</p><p>We examined whether it is possible to synthesize compounds that retain antiviral activity, but do not bind to HLA-B*57:01 and activate CD8+ T-cells.</p><p><bold>Materials and methods:</bold> Twenty-five abacavir analogues were synthesized with modifications around the cyclopropyl group with compounds divided into three main groups. Abacavir responsive CD8<sup>+</sup> T-cell clones were generated from healthy donors positive for the HLA-B*57:01 risk allele. IFN-g secretion was measured when the clones were cultured in the presence of autologous antigen presenting cells and abacavir or abacavir analogues using an ELISpot assay. Anti-viral activity of the analogues was assessed using a range of established assays. In silico docking studies were carried out to find potential binding orientations of the abacavir analogues within the F-pocket of HLA-B*57:01.</p><p><bold>Results:</bold> CD8<sup>+</sup> T-cell clones proliferated and secreted IFN-g in response to abacavir. Several analogues in groups 1 and 2 displayed some antiviral activity without triggering CD8+ T-cell responses. Molecular docking studies of these analogues to HLA-B*57:01 demonstrated a quantitative relationship between the protein binding and the T-cell response. These data prompted us to synthesize a 3rd group of compounds where the NH-cyclopropyl group of abacavir was replaced with substituted cyclic amine derivatives. This third series was subjected to additional antiviral activity and T-cell response assays and several molecules were shown to be devoid of T-cell activity, whilst maintaining a favourable antiviral profile.</p><p><bold>Conclusions:</bold> These studies demonstrate that modification of the cyclopropyl moiety of abacavir may result in compounds that retain the antiviral activity, without generating an unwanted T-cell response. This approach represents an exciting approach to the design of safe antiviral drugs eliminating the need for personalised medicine therapy regimes.</p></sec></sec></sec><sec id="Sec269"><title>P180 Generation and characterization of dapsone- and nitroso-dapsone-specific T-cell clones using lymphocytes from healthy volunteers</title><sec id="Sec270"><title>Abdulaziz Alzahrani<sup>1</sup>, Monday O.

Its use is associated with development of hypersensitivity in 0.5–3.6 % patients. HLA-B*13:01 is associated with an increased susceptibility to dapsone hypersensitivity but no studies have been carried out to determine the immunological mechanism(s) underlying the reactions and/or the role of the HLA risk allele in antigen presentation. The aims of this study were to: (1) Prime naive T-cells to dapsone and nitroso-dapsone (2) Generate dapsone-and nitroso-dapsone-specific T-cell clones from healthy donors and (3) Characterize the pathways of drug-specific T-cell activation.</p><p><bold>Materials and methods:</bold> Peripheral blood mononuclear cells (PBMCs) were isolated from healthy volunteers, and CD14<sup>+</sup> monocytes and naïve T-cells were isolated by magnetic bead separation. Monocyte-derived dendritic cells (DC) were used to prime naïve T-cells in the presence of either dapsone or nitroso dapsone using an established DC priming assay. Drug-specific T-cell clones were generated by serial dilution and repetitive mitogen stimulation. Antigen specificity was assessed by measurement of proliferation and cytokine release using [<sup>3</sup>H]-thymidine release and IFN-γ Elispot, respectively.</p><p><bold>Results:</bold> Moderate priming of naive T-cells to both dapsone-and nitroso-dapsone was detected but only five dapsone-specific T-cell clones were generated from one out of three donors tested. No nitroso-dapsone-specific T-cell clones were detected in any of the three donors. The dapsone-responsive clones were stimulated to proliferate is a dose-dependent manner, but showed no cross reactivity with nitroso-dapsone or three closely related structures. The clones secreted IFNgamma, IL-5 and IL-13 alongside the cytolytic molecule granzyme B. All of the dapsone-specific clones were CD4<sup>+</sup>, and showed MHC class II-restricted activation. Use of fixed or pulsed antigen presenting cells suggested that activation of T cell clones by dapsone did not require antigen processing.</p><p><bold>Conclusions:</bold> Naïve T cells were primed to both dapsone and nitroso dapsone. Dapsone-specific T-cell clones were activated via a processing independent pathway, thus suggesting a non-covalent interaction between drug, MHC and T cell receptor.

According to the hapten hypothesis, drug of low molecular weight can bind to proteins and form immunogenic complexes. Antigen presenting cells, such as dendritic cells (DCs), recognize and internalize drug hapten complexes, and digest them into benzylpenicillin-hapten peptides (BP-P), which are presented on HLA molecules to drug-specific T-cells. This lead to the immunization of the exposed person. There is in vitro evidence that T-cells from allergic patients react to benzylpenicillin-Human Serum Albumin (BP-HSA) bioconjugate and our group has recently shown the existence of naïve CD4<sup>+</sup> T lymphocytes specific to BP-HSA in healthy donors. In this context, we were interested in identifying BP-P from HSA able to immunize patients to BP thus contributing to hypersensitivity reactions.</p><p><bold>Materials and methods:</bold> We have considered HSA as a good model for BP haptenization since BP is known to bind covalently to HSA and because HSA is the most abundant protein in the sera. We have synthetized BP-HSA bioconjugate, investigated BP-HSA-specific naïve CD4<sup>+</sup> T-cell responses in healthy donors and identified BP binding positions on HSA using mass-spectrometry. Twelve 15-mer BP-P were identified as potential T-cell epitopes using the predictive IEDB computational approach and were synthesized using an original BP-lysine monomer. Naïve CD4<sup>+</sup> T cells from non-allergic donors were stimulated once a week with autologous DCs loaded with BP-HSA or BP-P to amplify BP-HSA- or BP-P-specific T-cells respectively. Activation of specific CD4<sup>+</sup> T-cells was detected using interferon-γ ELISpot and their frequency was calculated using the Poisson distribution.</p><p><bold>Results:</bold> In this study, BP-HSA- and BP-P-specific naïve CD4<sup>+</sup> T cells were detected in 15/16 and 11/14 of the tested healthy donors respectively. Most donors responded to 3 peptides with BP covalently bound on lysines 159, 212 and 525 respectively. Two of these benzylpenicillinoylated peptides (lysines 159 and 525) were found to induce peripheral blood mononuclear cells (PBMC) proliferation in patients with allergic reaction to BP using the lymphocyte transformation test.</p><p><bold>Conclusions:</bold> This study showed the capacity of BP-HSA to be recognized by naïve T-cells from multiple healthy donors and allowed the identification for the first time of BP-P responsible for naïve T-cell activation and immunization of allergic patients to BP.</p></sec></sec></sec><sec id="Sec275"><title>P182 Massive expansion of clonotypic and polycytotoxic CD8+ T cells in toxic epidermal necrolysis</title><sec id="Sec276"><title>Axel Patrice Villani<sup>1</sup>, Aurore Rozières<sup>2</sup>, Benoît Bensaïd<sup>3</sup>, Mathilde Tardieu<sup>3</sup>, Floriane Albert<sup>3</sup>, Virginie Mutez<sup>3</sup>, Tugba Baysal<sup>3</sup>, Marc Pallardy<sup>4</sup>, Janet Maryanski<sup>5</sup>, Jean-François Nicolas<sup>6</sup>, Osami Kanagawa<sup>3</sup>, Marc Vocanson<sup>3</sup></title><sec id="Sec277"><title><sup>1</sup>Inserm U1111 - CIRI, Lyon I University, Edouard Herriot Hospital, Lyon, France; <sup>2</sup>Inserm U1111 - CIRI, Lyon I University, Lyon, France; <sup>3</sup>Inserm U1111 - CIRI, Lyon, France; <sup>4</sup>INSERM UMR 996, Université Paris-Sud, Châtenay-Malabry, Lyon, France; <sup>5</sup>Unité de Thérapie Cellulaire et Génique (UTCG) and URE 004 (ImCelVir), Université Nice Sophia Antipolis, Nice, France; <sup>6</sup>Inserm U1111 - CIRI, Lyon I University, Lyon-Sud Hospital, Lyon, France</title><p><bold>Correspondence:</bold> Axel Patrice Villani</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P182</p><p><bold>Background:</bold> Toxic epidermal necrolysis (TEN) is a life-threatening and blistering adverse drug reaction, characterized by an acute epidermal necrolysis.

Particularly, limited and shared drug-specific CDR3 clonotypes were predominantly expressed in the blister cells and PBMC of SCAR patients. The in vitro drug-expanded T cells highly expressed the specific CDR3 clonotypes and produced granulysin upon drug stimulation. Furthermore, we generated drug-specific TCRalpha/beta recombinant protein, and found it could directly interact with the drug antigen and show cross-reactivity to the structure-related compounds or metabolites. Using in vitro cell culture and ELISPOT assays, we found that the specific TCRalpha/beta transfectants were activated upon drug stimulation, and the response was facilitated by the co-culture of antigen-presenting cells with the expression of matched HLA transgene.</p><p><bold>Conclusions:</bold> Our data suggest that clonotype-specific TCRalpha/beta directly interacts with drug antigens presented by HLA in the T cells-mediated drug hypersensitivity.

Clavulanic acid was incubated with N-acetyl lysine in phosphate buffer and the structures of adducts were characterised by mass spectrometry.

Dendrimers are monodisperse synthetic carriers, which chemical structure can be perfectly characterized. Their use compared to the conventional poly-<sc>l</sc>-lysine carrier improves the reproducibility and sensibility of in vitro tests to diagnose allergy. Moreover, increasing understanding of the immunological recognition of drug-carrier conjugates in vitro would help to improve diagnostic tests. Herein we include other penicillin epitope, AX (amoxicillin), and study Dendrimeric Antigen (DeAn) conjugates that contain two types of epitopes, BP and AX, in the same carrier dendrimer molecule. We hypothesize that the orientation and tridimensional disposition of the peripheral epitopes in the DeAn may play key roles in the IgE recognition.</p><p><bold>Materials and methods:</bold> Synthesis of DeAn conjugates was accomplished by reaction of generation 4 PAMAM (PolyAMidoAMine) dendrimers with either one kind of penicillin (BP or AX) or both penicillins (BP and AX). Their chemical and tridimensional structures were studied by mono- and bi-dimensional NMR (Nuclear Magnetic Resonance) and MDS (Molecular Dynamic Simulation). The conjugates were immunologically evaluated by RAST (Radio-Allergo-Sorbent-Test) inhibition using sera from 6 patients allergic to penicillins (selective and cross-reactive).</p><p><bold>Results:</bold> Spatial conformation showed differences between benzylpenicilloyl, with a hidden side chain, and amoxicilloyl, exposing the entire molecule outside the dendrimeric skeleton. Concerning immunological assays, at the maximum conjugate concentration, serum allergic to BP showed 80 % of RAST inhibition to both BP-DeAn and biepitope-DeAn, and negative to AX-DeAn. Sera allergic to AX showed 90 % of inhibition to both AX-DeAn and biepitope-DeAn, with no inhibition to BP-DeAn. All sera with cross-reactivity to both penicillins inhibited above 90 % to both AX-DeAn and biepitope-DeAn and above 60 % to BP-DeAn.</p><p><bold>Conclusions:</bold> Experimental data show less recognition of benzylpenicilloyl compared to amoxicilloyl units in those biepitope-DeAn, probably due to the different accessibility of the side chain of both penicillins to IgE recognition. Therefore there is a correlation between the tridimensional chemical structures of penicillin epitopes and the way DeAn are recognized by sIgE. Moreover, the biepitope DeAn conjugates could represent the basis of a novel method for screening a wider proportion of allergic patients with a single test.</p><p><bold>Keywords:</bold> Dendrimer; IgE; Penicillin</p></sec></sec></sec><sec id="Sec288"><title>P186 Dendrimeric antigens on solid supports: designed materials for IgE quantification</title><sec id="Sec289"><title>Yolanda Vida<sup>1</sup>, Maria Isabel Montañez<sup>2</sup>, Noemi Molina<sup>1</sup>, Daniel Collado<sup>1</sup>, Francisco Najera<sup>1</sup>, Adriana Ariza<sup>3</sup>, Maria Jose Torres<sup>4</sup>, Cristobalina Mayorga<sup>2</sup>, Ezequiel Perez-Inestrosa<sup>1</sup></title><sec id="Sec290"><title><sup>1</sup>Universidad de Malaga-IBIMA, Department of Organic Chemistry.

Advances in the fabrication of these surface materials are of growing interests in antibody-based diagnostic. We describe recent progress in the preparation of new materials for biosensor applications where Dendrimeric Antigens (DeAn), synthetic antigens where the role of the carrier protein is performed by a dendrimer, were supported on silica particles to assemble DeAn@SiO<sub>2</sub> composites. DeAn@SiO<sub>2</sub> containing the allergenic determinant to amoxicillin (AXO) has been studied for quantifying IgE specific to Amoxicillin.</p><p><bold>Materials and methods:</bold> We report on the use of silica particles as a solid support for Radio-Allergo-Sorbent-Test (RAST) with a view to its use as a complementary diagnostic method for identifying allergic responses to penicillin. We prepared nanoconjugated Dendrimeric Antigens (DeAn) consisting of second-generation PAMAM dendrimers (PAMAM-G2) peripherally decorated with the suspected amoxicillin hapten (AXO). These organic–inorganic hybrid materials were carefully characterized and the preparation methodology was checked to be highly reproducible. To study the potential of those composites in the detection and quantification of antibodies, they were clinically tested by RAST using sera from allergic patients and control individuals tolerant to this drug, according to conventional protocols applied in the clinical practice.</p><p><bold>Results:</bold> 0.4 mg of DeAn@SiO<sub>2</sub> composites were used in each assay, producing positive RAST results (7 %) in sera from three allergic patients. No signal was obtained in the RAST on two control individuals (even though being one of them with diagnosed immediate allergic reaction to benzylpenicillin), ensuring a high specificity in the detection of antibodies. Additionally, larger amounts of composites (1 and 1.6 mg) were used in the assays, increasing the RAST level for patients allergic (14 and 18 % respectively), which successfully improves the sensitivity of the test. The percentage of RAST obtained with the control gave negatives values, maintaining the specificity of the test.</p><p><bold>Conclusions:</bold> DeAn@SiO<sub>2</sub> composites, containing the allergenic determinant to AXO, proved effective in detecting and quantifying IgE in sera from patients allergic to amoxicillin, in a specific and selective way. This new material is thus promising candidate for improving in vitro clinical diagnostic practice.</p><p><bold>Keywords:</bold> IgE quantification; Dendrimers; Dendrimeric antigens</p></sec></sec></sec><sec id="Sec291"><title>P187 Development of a screening assay for drug hypersensitivity using naïve T cells from donors with seven different HLA class I risk alleles</title><sec id="Sec292"><title>Lee Faulkner, Sally Wood, Ana Alfirevic, Munir Pirmohamed, Dean J. Naisbitt, B. Kevin Park</title><sec id="Sec293"><title>University of Liverpool, Liverpool, United Kingdom</title><p><bold>Correspondence:</bold> Lee Faulkner</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P187</p><p><bold>Background:</bold> A small proportion of adverse drug reactions (ADRs) are due to drug hypersensitivity where the immune response causes an unexpected and sometimes severe clinical reaction. Genome-wide screens have identified many different genetic associations between drugs and ADRs. Of particular interest to hypersensitivity reactions are the HLA Class I and Class II risk alleles. Not all individuals with a HLA risk allele will develop hypersensitivity. Thus, the frequency/severity of a reaction is a function of the chemistry of the drug, the biology of the immune system, the genotype of the individual and the underlying medical condition.</p><p>Drug hypersensitivity reactions are rare and are rarely detected during clinical trials. It is only once the drug is widely prescribed that these reactions become apparent. Since hypersensitivity reactions that target skin and liver are a major cause of drug withdrawal from the market, there is a need to develop a screening assay which could potentially detect these reactions during drug development.</p><p><bold>Materials and methods:</bold> We have established a biobank of lymphocytes isolated from 1000 HLA-typed volunteers and have developed a DC priming assay which can prime naïve T cells to various drugs. The current form of the DC assay is labour intensive, requires large numbers of cells, uses different plate formats, has multiple readouts and takes 3–4 weeks to run. The aim is to modify this into a screening assay using a single plate with a single readout. We have selected up to 5 donors expressing seven different HLA Class I risk alleles: A*3101, A*3303, A*6801, B*1301, B*1502, B*5701 and B*5801. Ten donors without the HLA risk alleles will be included as negative controls and a unique donor exposed to nitroso-sulfamethoxazole (SMX-NO) will be used as a positive control.</p><p><bold>Results:</bold> Initial development has concentrated on using the SMX-NO and 2 β-lactam antibiotics as positive controls to optimise the assay conditions, to assess the frequency of T-cell responses and to measure the strength of the response induced. Early results show that proliferative responses to SMX-NO have been detected in the screening assay at a similar intensity to that detected in the existing form of the assay. Further work will concentrate on reproducibility and inter-donor variation.</p><p><bold>Conclusions:</bold> Once established, the screening assay will be used to investigate responses to ticlopidine, dapsone, carbamazepine, flucloxacillin allopurinol and abacavir.</p></sec></sec></sec><sec id="Sec294"><title>P188 Different patterns of recognition of structures derived from amoxicillin by IgE antibodies from patients with immediate hypersensitivity reactions to betalactams</title><sec id="Sec295"><title>Adriana Ariza<sup>1</sup>, Cristobalina Mayorga<sup>1</sup>, María Isabel Montañez<sup>2</sup>, María Salas<sup>3</sup>, Inmaculada Doña<sup>3</sup>, Ángela Martín-Serrano<sup>2</sup>, Ezequiel Pérez-Inestrosa<sup>4</sup>, Dolores Pérez-Sala<sup>5</sup>, Miguel Blanca<sup>3</sup>, Antonio E.

It is widely accepted the requirement of the binding of the AX to a carrier molecule for its optimal IgE recognition. Although the carrier molecule seems to form part of the antigenic determinant, its contribution in the pattern of response is not fully known. The aim of this work was to study the recognition of different structures derived from AX by IgE antibodies from allergic patients to this drug.</p><p><bold>Materials and methods:</bold> Patients (N = 21) with an immediate allergic reaction to AX and radioallergosorbent test (RAST) values >7 % were included. The IgE recognition study was performed by RAST inhibition using on the solid phase AX bound to poly-<sc>l</sc>-lysine and in the fluid phase the following inhibitors: AX, amoxicilloic acid, AX bound to butylamine (AXO-BA) and to human serum albumin (AXO-HSA), and fractions of different molecular weights of human serum modified with AX.</p><p><bold>Results:</bold> Two well-defined patterns of recognition were observed: A group of patients in whom AX itself was significantly higher recognized (Group A, N = 8) and another group of patients who preferentially recognized AXO-BA and AXO-HSA (Group B, N = 13). No significant differences were observed for amoxicilloic acid, being significantly the lowest recognized structure in both groups. Regarding the pattern of recognition of different fractions from AX-modified human sera, groups A and B showed differences, with a higher recognition of the lowest molecular weight fraction (<3 kDa) in Group A and no differential recognition in Group B.</p><p>Interestingly, all patients classified as Group A had selective allergic reactions to AX, and all those in Group B had cross-reactive reactions.</p><p><bold>Conclusions:</bold> Although both AX derivatives and carrier molecules are important for the IgE recognition, differences exist between patients with a selective or a cross-reacting response. In selective patients, it is necessary that the side chain of the AX was preserved in the AX-carrier adducts and exposed to the IgE, and this fact is influenced by the conditions in the formation of adducts. However, for cross-reactive patients, whose IgE antibodies recognize the AX side chain and part of the common structure of penicillins, the conditions for the generation of AX-carrier adducts seem not to be relevant for their recognition. The poor recognition of the amoxicilloic acid reinforces the need for binding the AX to a carrier molecule for an optimal recognition.</p><p><bold>Keywords:</bold> Amoxicillin; IgE; Carrier molecule; Hypersensitivity</p></sec></sec></sec><sec id="Sec297"><title>P189 High-resolution typing of HLA polymorphism and T-cell receptor repertoire for severe adverse drug reactions based on the cost-effective next-generation sequencing approaches</title><sec id="Sec298"><title>Tai-Ming Ko, Yuan-Tsong Chen, Jer-Yuarn Wu</title><sec id="Sec299"><title>Academia Sinica, Taipei, Taiwan</title><p><bold>Correspondence:</bold> Tai-Ming Ko</p><p><italic>Clinical and Translational Allergy</italic> 2016, <bold>6(Suppl 3)</bold>:P189</p><p><bold>Background:</bold> Immune-related severe adverse drug reaction (ADR) is widely hypothesised triggered by the combination of HLA, drugs, peptides, and T-cell receptor (TCR) molecules. Currently, numerous types of severe ADRs are reported to be related to particular HLA polymorphisms, such as HLA-B*15:02 allele associated with carbamazepine-induced Steven’s Johnson syndrome (SJS) and HLA-B*58:01 allele associated with allopurinol-induced severe cutaneous adverse reactions (SCARs). The use of TCR by drug-specific T cells is also considered a co-factor responsible for severe ADR. The major challenges of using Sanger sequencing, for high-throughput typing of HLA and TCR gene in large cohort studies, is the high cost involved. Moreover, it is unknown whether CBZ-SJS or allopurinol-SCARs is linked to more specified HLA types. Our aim was to identify which specified HLA types and TCR profiling correlated with CBZ-SJS or allopurinol-SCARs based on using cost-effective next-generation sequencing approaches.</p><p><bold>Materials and methods:</bold> We enrolled patients with CBZ-SJS, CBZ-tolerant subjects, patients with allopurinol-SCARs, allopurinol-tolerant subjects, and healthy controls. For HLA typing, we developed an analysis pipeline for illumina Miseq or PacBio sequencing platform. For TCR typing, a widely used primer set was used and an analysis pipeline for illumina Miseq or Hiseq sequencing platform was developed. Sanger sequencing for the validation of HLA and TCR was performed.</p><p><bold>Results:</bold> We genotyped all major HLA regions, including HLA-A, HLA-B, HLA-C, HLA-DPB1, HLA-DQB1, and HLA-DRB1, in all the subjects. Compared with sequence-based typing ($400 per sample) for HLA typing, the cost based on next-generation sequencing ($240 per sample) was reduced. CBZ-SJS patients or allopurinol-SCAR patients were HLA-B*15:02:01-positive or HLA-B*58:01:01-positive, respectively. For TCR, we genotyped all the V beta subfamilies. Dominant CDR3 sequences were verified by Sanger sequencing. Compared with Sanger sequencing ($500 per sample), the cost based on next-generation sequencing ($50 per sample) was much lower. Additionally, novel TCR clonotypes, possibly associated with SJS patients, were identified.</p><p><bold>Conclusions:</bold> A cost-effective method for high-throughput and high-resolution typing of HLA and TCR was developed. HLA-B*15:02:01 and HLA-B*58:01:01 were found as more specified HLA genotypes for developing CBZ-SJS and allopurinol-SCARs, respectively.</p></sec></sec></sec><sec id="Sec300"><title>P190 Identification and fate of intracellular proteins haptenated by amoxicillin</title><sec id="Sec301"><title>Francisco J.

In the allergic response, the adduct formation between small drugs and proteins, called haptenation, allows drugs to be recognized as antigens by the immune system. Moreover, it has been hypothesized that structures from target proteins can also contribute to the formation of the antigenic determinants. Identification of protein targets for haptenation is relevant for their potential use in novel diagnostic tools as well as for understanding the complete mechanisms involved in antigen presentation and the role played by the cells that participate in allergy induction. In recent years our lab has undertaken the identification of targets proteins for the haptenation by beta-lactams.</p><p><bold>Materials and methods:</bold> We have attempted the identification of protein targets for covalent modification by amoxicillin (AX) and a biotinylated analogue (AX-B) as model compounds. To accomplish these aims, we decided to use a B-lymphocyte cell line as cellular model. The identification of the proteins haptenated by AX and AX-B has been approached with mass spectrometry experiments. In addition, intercellular communication mediated by vesicular delivery of molecular messages has been explored by microscopy techniques.</p><p><bold>Results:</bold> In our experiments we have observed a complex pattern of proteins modified by amoxicillin. Among them, we have isolated and identified several novel targets for haptenation by AX in B-lymphocytes. In addition, these haptenated proteins have been observed both intracellularly and in the conditioned medium, where they were found both in soluble and vesicular fractions.</p><p><bold>Conclusions:</bold> Our results indicate that intracellular proteins may be haptenated by beta-lactam antibiotics and reach the extracellular medium.

The incidence of these reactions is so low that these adverse events cannot be attributed to the normal pharmacological action of a drug, but are probably due to the individual biology of a patient. To support this claim, an increasing number of genetic associations have been found in cases of iDILI, and many of these are with HLA alleles. This indicates that iDILI may have an immunological aetiology and there is increasing evidence to support this. For example: the detection of T-cells in liver biopsies from iDILI patients and the isolation of drug specific T-cells in patients suffering from flucloxacillin and co-amoxiclav induced liver injury. This sets a precedence to investigate other iDILI drugs such as terbinafine in the context of drug hypersensitivity reactions. Terbinafine can form a chemically reactive metabolite and like β-lactam antibiotics, may form drug-protein haptens to activate an immune response. Although the hapten model for drug hypersensitivity is well established, the precise nature of the drug antigen is unclear. The aim of this study is to investigate the formation of terbinafine adducts using a chemically reactive metabolite of terbinafine: allylic aldehyde, 7,7-dimethylhept-2-ene-4-ynal (TBF-A).</p><p><bold>Materials and methods:</bold> TBF-A was incubated for 24 h at a 10:1 molar ratio for synthetic peptides and a 1:1 ratio for other molecules. Mass spectrometric analysis was conducted using an API 4000 or an QTRAP 5500 hybrid quadrupole-linear ion trap mass spectrometer (AB Sciex). Conjugates were detected using multiple reaction monitoring and also enhanced product ion scanning methods</p><p><bold>Results:</bold> TBF-A showed binding to <italic>N</italic>-acetyl cysteine and glutathione but not to <italic>N</italic>-acetyl lysine. Additionally, TBF-A was shown to bind covalently to glutathione s-transferase pi. Following incubation with human serum albumin, no conjugates were detected. Synthetic cysteine containing peptides were also generated and shown to bind TBF-A.</p><p><bold>Conclusions:</bold> TBF-A binds to cysteine residues in small molecules, larger proteins and also in synthetic peptides. Thus, we are now conducting additional studies to isolate TBF-A specific T-cells in order to investigate whether formation of this metabolite is important for the activation of the adaptive immune system in patients with iDILI.</p></sec></sec></sec><sec id="Sec306"><title>P192 MicroRNAs dysregulation in PBMCs from drug hypersensitivity patients during drug challenge in vitro</title><sec id="Sec307"><title>Alejandra Monroy Arreola<sup>1</sup>, Jesus Agustin Badillo Corona<sup>1</sup>, Silvia Mendez Flores<sup>2</sup>, Judith Dominguez Cherit<sup>2</sup>, Dean J.

During the last 20 years, we have gained insight into the immunological mechanism(s) behind different forms of cutaneous hypersensitivity, but our knowledge of post-transcriptional immune regulators remains poorly understood. MicroRNAs (miRNAs) play a key role in several immunological processes and in the pathogenesis of several diseases including severe skin conditions; nonetheless, their cellular origin and the changes in the expression as a result of drug exposure needs to be further investigated.</p><p><bold>Materials and methods:</bold> Two allergic patients to sulfamethoxazole (SMX1 and SMX2) and one allergic patient to levofloxacin (LFV1) were enrolled in the study. Approval for the study was obtained from local research ethics committee, and informed written consent was obtained from each donor. The presence of drug specific T-cells was determined by LTT. Additionally, PMBCs (1.5 × 10<sup>5</sup> cells/ml) from each patient were incubated by triplicate in cell culture alone or in the presence of the culprit drugs at different concentrations. The change in the pattern of expression of the miRNAs was compare between drug free cells and drug incubated cells at 0, 12, 24 and 48 h by RT-PCR using commercial specific probes for miR-18a, -21, -142 and -155. The U6 gene was used as reference, and the relative expression was calculated using the delta Cq method.</p><p><bold>Results:</bold> Positive stimulation indexes were obtained from the three patients at different concentrations. Moreover, a significant increase in the expression of miR-18a, -21, -142 and -155 was detected after 12–48 h in the PBMCs of all the patients. Quantitative relative expression of the different miRNAs showed a fold change between 2 and 100 during the incubation time when compared with cells without drug. When a different drug, not related with the reaction, was used, the change in the pattern of expression was reduced or similar to basal levels.</p><p><bold>Conclusions:</bold> Our findings clearly show that the incubation of the culprit drugs with PBMCs from hypersensitive patients modify the expression of miRNAs in a dose and time dependent manner. At the presence, we are evaluating the change in the pattern of expression of miRNAs in PBMCs of hypersensitive patients caused by anticonvulsants and in patients with severe cutaneous reactions (Table <xref rid="Tab11" ref-type="table">11</xref>).<table-wrap id="Tab11"><label>Table 11</label><caption><p>Clinical information and functional assays results from three hypersensivity patients to antibiotics</p></caption><table frame="hsides" rules="groups"><thead><tr><th align="left" colspan="4">Patient information</th><th align="left">Lymphocyte transformation test</th><th align="left" colspan="4">Change in the pattern of expresion of miRNAs with drugs</th></tr><tr><th align="left">Code</th><th align="left">Sex</th><th align="left">Age</th><th align="left">Skin reaction</th><th align="left">SI/Drug (μg/ml)</th><th align="left">miRNA</th><th align="left">Drug (μg/ml)</th><th align="left">Relative expression</th><th align="left">Time (h)</th></tr></thead><tbody><tr><td align="left">SMX1</td><td align="left">F</td><td char="." align="char">60</td><td align="left">MPE</td><td align="left">5.0/SMX (200)<break></break>5.2/SMX-NO (20)</td><td align="left">142</td><td align="left">SMX (400)</td><td char="±" align="char">153 ± 28</td><td char="." align="char">12</td></tr><tr><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left">18a</td><td align="left">SMX-NO (12)</td><td char="±" align="char">71.6 ± 1.21</td><td char="." align="char">24</td></tr><tr><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left">155</td><td align="left">SMX-NO (12)</td><td char="±" align="char">5.6 ± 1.1</td><td char="." align="char">24</td></tr><tr><td align="left">SMX2</td><td align="left">M</td><td char="." align="char">35</td><td align="left">MPE</td><td align="left">2.0/SMX (400)<break></break>3.0/SMX-NO (20)</td><td align="left">18a</td><td align="left">SMX (400)</td><td char="±" align="char">2.5 ± 0.6</td><td char="." align="char">24</td></tr><tr><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left">21</td><td align="left">SMX-NO (12)</td><td char="±" align="char">6.3 ± 3.2</td><td char="." align="char">24</td></tr><tr><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left">142</td><td align="left">SMX (400)</td><td char="±" align="char">3.9 ± 0.7</td><td char="." align="char">24</td></tr><tr><td align="left">LVF1</td><td align="left">M</td><td char="." align="char">47</td><td align="left">MPE</td><td align="left">2.0/LVF (10)</td><td align="left">142</td><td align="left">LVF (10)</td><td char="±" align="char">12.2 ± 0.9</td><td char="." align="char">24</td></tr><tr><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left">18a</td><td align="left">LVF (10)</td><td char="±" align="char">4.0 ± 0.4</td><td char="." align="char">48</td></tr><tr><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left"></td><td align="left">155</td><td align="left">LVF (10)</td><td char="±" align="char">5.1 ± 1.1</td><td char="." align="char">48</td></tr></tbody></table><table-wrap-foot><p>Relative expression results are presented as the Mean ± SD obtained by the delta Cq method</p><p><italic>SMX</italic> sulfamethoxazole, <italic>SMX</italic>-<italic>NO</italic> sulfamethoxazole nitroso, <italic>LVF</italic> levofloxacin, <italic>MPE</italic> maculopapular exanthema</p></table-wrap-foot></table-wrap></p><p><bold>Keywords:</bold> MicroRNAs; Drug hypersensitivity; Mechanisms</p></sec></sec></sec><sec id="Sec309"><title>P193 NSAIDs-exacerbated cutaneous disease: high throughput gene expression profiling</title><sec id="Sec310"><title>José Antonio Cornejo-García<sup>1</sup>, James Perkins<sup>2</sup>, Natalia Blanca-López<sup>3</sup>, Diana Pérez-Alzate<sup>3</sup>, Raquel Jurado-Escobar<sup>2</sup>, Inmaculada Doña<sup>4</sup>, Gador Bogas<sup>4</sup>, María J.

Thus we can classify these manifestations as immediate, accelerated or delayed, or simply as immediate or not immediate.</p><p><bold>Materials and methods:</bold> Patient who comes to be attended after having suffered 2 episodes of RAM after taking amoxicillin. Both episodes coursed with generalized skin rash, 8 days after taking amoxicillin 500 per a picture of tonsillitis and the second 5 days after taking amoxicillin 500 per a tooth extraction. On both occasions the picture is manifested after a latency period of 48–72 h after the last intake. Skin tests with amoxicillin (DAP DIATER kit) by prick test and ID to 1:10 and 1:100 and undiluted. Oral challenge test against Cefuroxime increasing doses up to the maximum cumulative dose of 500 mg. RAST tests against penicilloyl G and V, ampicillin, amoxicillin and cefaclor.</p><p><bold>Results:</bold> The skin tests were positive for amoxicillin ID undiluted, 1:10 and 1:100 at 72 h. The oral food challenge to cefuroxime at the doses administered was negative. RAST tests against penicilloyl G and V, Ampicillin, Amoxicillin and negative cefaclor.</p><p><bold>Conclusions:</bold> We report a case of delayed reaction to amoxicillin with tolerance to cefuroxime, where the history and skin tests were essential in the diagnosing of this case.</p><p><bold>Keywords:</bold> Diagnostic; Skin test; Amoxicillin; Non-immediated</p></sec></sec></sec></sec></body><back><fn-group><fn><p>These abstracts have been published as part of Clinical and Translational Allergy Volume 6 Suppl 2, 2016.
