Unique Identifier : AIDSLINE ICA10/94369985 AB OBJECTIVE: The incidence of anal cancer is increasing in association with the AIDS epidemic. This disease is associated with human papillomavirus (HPV) infection. However, little is known about anal HPV infection in men with advanced HIV disease. In this study, we characterized changes in HPV type and level over 1 year in this population. METHODS: HPV testing was performed in 57 homosexual men with symptomatic HIV disease at baseline, and at 6 and 12 months using 2 methods. L1 consensus primer PCR was used to detect low level or high level infection with HPV types 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, and 52. Hybrid Capture (HC) was used to detect high level infection (indicating active viral replication) with HPV groups 6/11, 42/43/44, 16/18, 31/33/35, and 45/51/52/56, as well as HPV type 16 alone. The concentrations of HPV 16 and 6/11 DNA in the anal specimens were calculated using standard curves at 6 months into the study. RESULTS: The prevalence of PCR positivity among the men increased from 67% to 84% after one year. At baseline, multiple types were found in 56% of men with a mean of 1.9 types. After one year, this rose to 81% with a mean of 3.1 types. The prevalence of HC positivity increased from 54% to 77% after one year. At baseline, multiple groups were found in 32% of men with a mean of 1.1 groups. After one year, this rose to 50% with a mean of 1.8 groups. Among those with HPV 16 or 6/11 by HC at 6 months, the median HPV 16 level was 125 pg/ml (n = 10, range 11-2080), and 6/11 was 912 pg/ml (n = 7, range 28-2860). CONCLUSIONS: HPV infection persists in this population, including low level infection. The proportion of men with multiple types is high and continues to increase over time. The concentrations of different HPV types are also very high but vary widely and there is no clear selective advantage of one group over the other.
