BACKGROUND: Since the introduction of highly active antiretroviral therapy (HAART), an increase in the frequency of human papillomavirus-associated oral lesions (HPV-OL) has been observed. Thus, the aim of this study was to determine the prevalence and factors associated with HPV-OL in Mexican HIV-infected patients, as well as its genotyping, in the HAART era. METHODS: In a cross-sectional study developed at an HIV/AIDS referral center in Mexico City, HIV-infected patients were consecutively included from 2004 to 2011. An oral exam was performed; lymphocyte CD4(+) count, HIV-viral load, CDC-stage, and HAART use were recorded. HPV-OL samples were taken for routine histopathological analysis (H-E) and HPV-DNA amplification/sequencing. Logistic regression models were performed and the interactions tested using the STATA software. RESULTS: Among 787 HIV patients, 55 (6.9%) showed HPV-OL. HPV-OLs were independently associated with age (≥40 years) and with a longer time of HAART use (≥12 months). The most frequent lesion was squamous cell papilloma in 22 (40%) cases, followed by multifocal epithelial hyperplasia in 15 (27.3%) cases. Labial mucosa was the most common site involved (56.4%). Of the sequences obtained, 65.4% corresponded to low risk and 11.5% to high risk. Mixed high- and low-risk infection were identified in 7.7% of the cases. CONCLUSIONS: Human papillomavirus-associated oral lesions were associated with older age and longer HAART use. All lesions were benign in nature and most of the HPV sequences corresponded to low-risk types. The rise of HPV-OLs in HIV patients on HAART may be related with the longer life expectancy of individuals with an impaired immune system rather than a direct effect of HAART.
