Oral and cervical HPV infection in HIV-positive and HIV-negative women attending a sexual health clinic in São Paulo, Brazil.

Objective: To investigate the prevalence of HPV infections in the oral and cervical mucosa of HIV-positive and HIV-negative women attending a sexual health clinic.
Methods: One-hundred HIV-positive women and 100 HIV-negative women were recruited from a sexual health clinic in São Paulo, Brazil. All participants were given an oral and cervical examination. Cytologic samples were evaluated via HPV DNA test.
Results: In oral samples, HPV DNA was observed in 11 women from the HIV-positive group and 2 from the HIV-negative group. High-risk HPV subtypes were prevalent in both groups and no difference between groups was detected. HPV DNA was detected in cervical scrapings from 41 HIV-positive women and 45 HIV-negative women (P=0.67). No participants showed oral lesions, whereas 15 HIV-positive and 17 HIV-negative women presented with macroscopic genital lesions.
Conclusion: HPV is detected more often in cervical scrapings than in oral samples. However, HPV oral shedding is more frequent in HIV-positive than in HIV-negative individuals. Concurrence of infection (high and low risk) was not observed in oral and cervical mucosa.
