Abstract

AbstractObjectives

To describe the fasting serum lipid and glucose profiles of HIV-positive Nigerian children and determine the prevalence and risk factors for dyslipidaemia and hyperglycaemia, which are risk factors for cardiovascular diseases.

Methods

This was a comparative cross-sectional study carried out at the Paediatric Infectious Disease Clinic (PIDC) of the Jos University Teaching Hospital (JUTH) for HIV-positive children and at two primary schools in Jos for HIV-negative children as controls. One hundred and forty-two HIV-positive children aged 6–18 years and an equal number of controls were studied by determining their fasting serum lipid and glucose levels. The prevalence of dyslipidaemia and hyperglycaemia was determined and their risk factors obtained using multivariate logistic regression. P values of less than 0.05 were considered statistically significant.

Results

Mean triglyceride levels were significantly higher in HIV-positive children compared with controls at 87.2 mg/dL (95% confidence interval [CI] 79.4–95.0) and 68.1 mg/dL (95% CI 62.5–72.7), respectively (P<0.001). There were no significant differences in mean glucose levels. Dyslipidaemia was significantly higher in HIV-positive children (21.8%) compared with controls (12.7%; P=0.04). Total serum cholesterol was elevated in 17 (12.0%) HIV-positive participants compared with seven (4.9%) of controls (P=0.02). Children on lopinavir/ritonavir (LPV/r) and those with no significant or mild disease had a significantly higher prevalence of hypercholesterolaemia (33.3% vs 4.8% and 14.5% vs 0.0%, respectively; P<0.001).

Conclusion

HIV-positive children on antiretroviral (ARV) drugs, especially LPV/r, should have their lipids regularly monitored as those with dyslipidaemia stand the risk of subsequently developing cardiovascular diseases.

<sec id="jve7-sec-0005">
<title id="jve7-title-0007">Introduction</title>
<p id="jve7-para-0005">With approximately 35 million individuals being infected with HIV/AIDS worldwide, the dangers of this disease cannot be overemphasised
<xref rid="jve7-bib-0001" ref-type="bibr">[1]</xref>
. Two-thirds of these individuals live in sub-Saharan Africa and in 2014, an estimated 3.4 million individuals were living with HIV/AIDS in Nigeria, approximately 10% of whom were children
<xref rid="jve7-bib-0002" ref-type="bibr">[2]</xref>
.</p>
<p id="jve7-para-0006">The improvement in the survival rates for both adults and children living with HIV resulting from the use of antiretroviral (ARV) drugs has brought with it the metabolic effects of some of these drugs including hyperglycaemia and dyslipidaemia including increased total cholesterol (hypercholesterolaemia), increased low density lipoprotein cholesterol (LDL-c), decreased high density lipoprotein cholesterol (HDL-c) and hypertriglyceridaemia. These effects are established risk factors for cardiovascular diseases (CVDs) such as coronary artery disease, myocardial infarction, angina and stroke as they promote plaque formation, leading to arterial narrowing, which can contribute to significant morbidity and mortality later in life
<xref rid="jve7-bib-0003" ref-type="bibr">[3,4]</xref>
. In addition to the effects of ARVs, HIV itself can also directly induce endothelial cell injury resulting in arterial plaque formation
<xref rid="jve7-bib-0005" ref-type="bibr">[5]</xref>
. HIV-positive children may have a higher risk of developing CVD later in life than HIV-negative children as a result of these metabolic complications.</p>
<p id="jve7-para-0007">Dyslipidaemia and hyperglycaemia have been shown to be more prevalent in individuals with HIV/AIDS, especially those on ARVs, compared with the general population
<xref rid="jve7-bib-0006" ref-type="bibr">[6]</xref>
. All classes of ARV have been shown to be associated with metabolic effects but protease inhibitors (PIs) are particularly associated with the development of hyperlipidaemia because they inhibit differentiation of adipocytes and increase lipolysis leading to hypercholesterolaemia, hypertriglyceridaemia and an increase in LDL cholesterol
<xref rid="jve7-bib-0007" ref-type="bibr">[7]</xref>
. PIs also reduce glucose transportation inducing insulin resistance (IR), which will lead to hyperglycaemia
<xref rid="jve7-bib-0007" ref-type="bibr">[7,8]</xref>
. The nucleoside inhibitors of retrotranscriptase (NRTIs), especially stavudine (d4T), also inhibit mitochondrial DNA polymerase within adipocytes that results in mitochondrial injury, and this leads to hypercholesterolaemia and hypertriglyceridaemia
<xref rid="jve7-bib-0008" ref-type="bibr">[8]</xref>
.</p>
<p id="jve7-para-0008">The metabolic effects of HIV and/or ARV drugs in HIV-positive children in Jos, Nigeria has, however, not been studied and currently data on the lipid and glucose profile in the Nigerian paediatric HIV population are sparse
<xref rid="jve7-bib-0009" ref-type="bibr">[9]</xref>
. Closing the knowledge gap will help in adequate screening and risk stratification of these children in order to prevent later development of CVD
<xref rid="jve7-bib-0010" ref-type="bibr">[10]</xref>
. The present study, therefore, aims to describe the prevalence and risk factors for dyslipidaemia and hyperglycaemia in HIV-positive Nigerian children compared with age- and sex-matched controls. This would help to improve the level of care in these children and open opportunities for further longitudinal research.</p>

<p id="jve7-para-0047">This descriptive cross-sectional study investigated serum lipid and glucose profiles, which are documented risk factors for later development of CVD, in 142 HIV-positive children and compared them with age- and sex-matched controls. It also identified the relationship of certain parameters such as age, clinical and immunological stage of disease, and the use of various ARV combinations between dyslipidaemia in participants.</p>
<p id="jve7-para-0048">The prevalence of dyslipidaemia in HIV-positive children in this study was 21.8%, a finding that is similar to that from other studies, ranging between 19.3% and 48%
<xref rid="jve7-bib-0017" ref-type="bibr">[17–19]</xref>
. In this study, hypercholesterolaemia was the most common type of dyslipidaemia found and was present in 12.2% of the HIV-positive participants. This is similar to the 13% reported in the US and 14.8% in India
<xref rid="jve7-bib-0018" ref-type="bibr">[18]</xref>
, but lower than the 27.2% detected by a study in Spain

<p id="jve7-para-0049">In studies where more HIV-positive children have advanced disease, hypertriglyceridaemia is a common finding. Blazquez
<italic>et al.</italic>
reported a prevalence rate of 39.8% among HIV-positive children in Spain where 67% of the participants had severe disease and a rate of 83% in a study in Uganda where up to 65% of the children had severe HIV infection. In this study, only 10% of participants had severe infection, which could explain the lower prevalence rate of hypertriglyceridaemia (8.6%) obtained
<xref rid="jve7-bib-0020" ref-type="bibr">[20,21]</xref>

<p id="jve7-para-0050">Protease inhibitors (PIs) have been significantly associated with dyslipidaemia in other studies
<xref rid="jve7-bib-0022" ref-type="bibr">[22]</xref>
, a finding also in this study where the use of second-line ARV combinations that contained the protease inhibitor LPV/r was significantly associated with hypercholesterolaemia, hypertriglyceridaemia and increased LDL-c when compared with participants on first-line drugs. In a study by Aldrovandi
<italic>et al.</italic>
<xref rid="jve7-bib-0023" ref-type="bibr">[23]</xref>
, PI use was associated with elevated triglycerides among 52% of HIV-positive children while Carter

<xref rid="jve7-bib-0024" ref-type="bibr">[24]</xref>

the use of the NNRTIs nevirapine (NVP) and efavirenz (EFV) was linked to a high HDL-c value, also known as ‘good’ cholesterol. Therefore, it is not surprising that 95.1% of the HIV-positive children in this study had high HDL-c levels because 72% of them were on ARV combinations that contained either NVP or EFV. A study in Zimbabwe found that children on (zidovudine) ZDV had lower total cholesterol, HDL-c and TG than those on NVP or EFV
<xref rid="jve7-bib-0026" ref-type="bibr">[26]</xref>
. Also, decreased serum concentrations of HDL-c in individuals who are ARV naive has been shown to point to chronic inflammation
<xref rid="jve7-bib-0027" ref-type="bibr">[27]</xref>
. Participants in this study had a significantly higher mean serum HDL-c compared with the control group, which could imply good control of chronic inflammation. Decreased HDL-c was the least common of the dyslipidaemias and this has also been shown in several other studies
<xref rid="jve7-bib-0028" ref-type="bibr">[28–30]</xref>
.</p>
<p id="jve7-para-0052">Only one study participant and one control group member had an FBS level of greater than 100mg/dL, a finding that is in keeping with studies from Brazil and Thailand where no children had elevated FBS levels
<xref rid="jve7-bib-0031" ref-type="bibr">[31,32]</xref>
. The latter study showed that the prevalence of increased FBS was low in patients on NNRTIs (NVP or EFV), a finding also present in this study. The child who had elevated FBS was, however, on an ARV combination that had two NRTIs (lamivudine and abacavir) and efavirenz, a combination that has been shown to be associated with insulin resistance
<xref rid="jve7-bib-0033" ref-type="bibr">[33]</xref>
. There were only three children on this ARV combination and this number is too small to draw up any statistically meaningful conclusions.</p>
<p id="jve7-para-0053">The virus itself could initiate a systemic inflammatory response in an individual as a result of persistent infection leading to hypertriglyceridaemia
<xref rid="jve7-bib-0034" ref-type="bibr">[34]</xref>
. In this study, only two children who were newly diagnosed with HIV, were not yet on ARV drugs and had no lipid abnormalities. However, this number is too small to make any statistical conclusion.</p>
<p id="jve7-para-0054">The present study shows that the mean weight and height were significantly lower in the HIV-positive participants when compared with the control group, a finding that has been found in several studies. It has been attributed to the chronic nature of the disease with its related increase in metabolism and caloric demands, comorbidities, medications and food insecurity
<xref rid="jve7-bib-0035" ref-type="bibr">[35]</xref>
. In the study population, a higher proportion had a lower socio-economic background, which raises the question of the availability of adequate nutrition
<xref rid="jve7-bib-0036" ref-type="bibr">[36]</xref>
.</p>
<p id="jve7-para-0055">An inverse relationship has been found between socio-economic status and smoking, a finding also observed in this study where second-hand smoking was more commonly found in the participants from a lower socio-economic background

.</p>
<sec id="jve7-sec-0018">
<title id="jve7-title-0020">Limitations</title>
<p id="jve7-para-0056">Due to cost implications, we were not able to assess the presence and prevalence of insulin resistance. There were also very few HIV-positive children attending the PIDC who were not on ARVs making it difficult to compare the effects of ARVs as a whole on lipid profile in HIV-positive children.</p>
</sec>

<sec id="jve7-sec-0019">
<title id="jve7-title-0021">Conclusion</title>
<p id="jve7-para-0057">Regular monitoring of the lipid profile of HIV-positive children, especially those on LPV/r, will be clinically useful in determining those who may have a higher CVD risk. Longitudinal and larger multicentre studies will be useful in determining the progression of dyslipidaemias in HIV-positive children over time. Because the safety of only a few ARV drugs has been well established in children, more research is needed to broaden the choice of drugs available for treating HIV infection in these individuals where it may be necessary to switch to other types of PI-based therapy or a different class of ARV
