Abstract

This study aims to describe and characterize incident HR-HPV infections and associated diseases in HIV-infected women. 805 HIV-infected women enrolled in the VALHIDATE Study were screened and followed-up for HPV by co-testing. Social, behavioral and health data were collected. HPV-DNA positive samples were typed using a commercial kit or RFLP analysis. Conventional Pap-smears were evaluated using the 2001 Bethesda System. The participants with abnormal cytological results were referred for colposcopy. 565 HIV-infected women (median age: 43 years) were analysed, 40.9% had >5 lifetime sexual partners, 77.2% contracted HIV through sexual intercourse, 93% were receiving antiretroviral treatment and 77.3% had undetectable HIV-RNA. The women underwent 1254 follow-ups (median follow-up: 33 months) for 1430.6 PersonYear-Follow-Up. 37.4% of baseline HPV-negative women acquired incident HPV-infections, 69.6% of which were HR-HPVs. HPV-53 was the most common HPV type detected (9.3%). 18.2% of women showed incident or progressive cytological abnormalities (7.8% ASC-US, 9.7% LSIL and 0.6% HSIL) and colposcopy revealed CIN2 (N = 2), CIN1 (N = 2) and VIN3 (N = 1). The preventable fraction of incident infections was 11.3%, 16.7%, and 35.2% for the 2v-4v-9v-HPV vaccines respectively (χ2 p < 0.0001). The overall burden of incident lesions attributable to the vaccine types were 9.1% for 2v-, 14.5% for 4v- and 30.9% for 9v-vaccine. High HPV incidence rates and high percentages of multiple HR-HPV infections were observed in a cohort of HIV-infected women receiving effective antiretroviral treatment. Primary prevention strategies based on the new 9v-HPV vaccine may help to prevent incident infections and disease progression in this cohort of women.
