Abstract
The aim of this study was to investigate the association of EBV and HPV with gingivitis and/or periodontitis according to the immunologic status. To this end, 74 oral biopsies from transplanted and non-transplanted individuals with the abovementioned oral manifestations were submitted to a screening by PCR for both viruses. According to the results, EBV was strongly associated with gingivitis and/or periodontitis in transplanted individuals (

However, it is known that several factors can influence the viral detection in periodontitis, including the sample type, methodological approaches and geographical/ethnical differences regarding the herpesviruses occurrence<xref rid="B10" ref-type="bibr"><sup>10</sup></xref>. Moreover, herpesviruses were found in association with oral ulcerations after transplantation. Van der Beek <italic>et al.</italic><xref rid="B11" ref-type="bibr"><sup>11</sup></xref> described the presence of EBV DNA in 24% of stem cell-transplanted patients with oral ulcerations. This frequency is compatible with the hereby described, despite originating from different patients with other oral lesions. Hence, the EBV involvement with different oral lesions after transplantation deserves further studies.</p><p>Another important virus associated with oral lesions, especially precancerous and cancers from the oropharynx and the oral cavity, is HPV. It has been demonstrated that HPV can infect periodontal pocket basal cells. Additionally, the chronic inflammation in periodontitis and gingivitis could favor the HPV persistence and replication, serving as a reservoir of HPV in the oral cavity<xref rid="B10" ref-type="bibr"><sup>10</sup></xref>. In this study, we found a HPV prevalence of 41.9% in lesion biopsy samples, but unrelated to transplantation. Association studies between HPV gingival infection and periodontitis are controversial. Jacob <italic>et al</italic>.<xref rid="B13" ref-type="bibr"><sup>13</sup></xref> studying healthy individuals with and without periodontal disease did not find any positive gingival tissue for HPV-16. These results were similar to those obtained by Horewicz <italic>et al.</italic><xref rid="B14" ref-type="bibr"><sup>14</sup></xref>, with no detection of HPV-16 in either periodontitis or gingivitis. Nevertheless, a recent study showed a slightly higher HPV prevalence (46%) in gingival crevicular fluid of HIV-positive adults, being HPV-6 and HPV-11 the only two genotypes found<xref rid="B15" ref-type="bibr"><sup>15</sup></xref>. </p><p>In regard to the association of EBV with oral lesions in Tx patients, it seems that the functional impairment of T cell surveillance induced by the immunosuppressive treatment is the main driver of viral reactivation, as observed in other EBV-induced diseases<xref rid="B16" ref-type="bibr"><sup>16</sup></xref>. Therefore, it's possible that EBV could induce tissue lesion in an immune permissive environment<xref rid="B9" ref-type="bibr"><sup>9</sup></xref>, although other uninvestigated agents/factors might be involved. HPV is also benefited by immunosupression, and is associated with more aggressive forms of tumors in transplant recipients<xref rid="B17" ref-type="bibr"><sup>17</sup></xref>. The lack of association between transplantation and oral lesions indicate that HPV is not involved in the pathogenesis of non-papillomatous oral injuries or is not enhanced by immunosupression in this particular clinical manifestation. </p><p>In conclusion, we observed a significant correlation between an oncogenic epitheliothropic agent, the EBV, with mucosal lesions in Tx individuals. Although frequently found in oral tissue, the same observation was not valid for HPV. Being persistent agents, papillomaviruses and herpesviruses should be monitored in longitudinal studies in order to observe their long term effects in the host, especially in immunocompromised individuals.</p></body><back><ref-list><title>REFERENCES</title><ref id="B1"><label>1</label><element-citation publication-type="journal"><person-group
