BACKGROUND: We studied the type-specific infection of human papillomavirus (HPV) at the anal canal and penile site in a cohort of HIV-infected men.

METHODS: Prevalence, clearance, and incidence of specific HPV types in the anal canal and penis were determined in 733 HIV-infected men from the Spanish CAn Ruti HIV+ Men ([CARH•MEN]) cohort (538 men who have sex with men [MSM] and 195 heterosexual men).

RESULTS: In both groups, the most prevalent high-risk type was HPV-16 (anal canal [31.6% MSM; 6.8% heterosexual] and penis [4.8% MSM; 6.8% heterosexual]). The most prevalent low-risk type was HPV-6 (anal canal [23.2% MSM; 12.8% heterosexual], penis [8.1% MSM; 8.9% heterosexual]). Anal prevalence was significantly higher in MSM, as was incidence, except for HPV-16, which was similar between male groups (5.9 new cases per 1000 person-months [95% confidence interval, 4.3-7.9] in MSM; 4.4 [95% confidence interval, 2.5-7.2] in heterosexual men; P > 0.05). The anal clearance rate of the different HPV types and retention time of infection were similar in both groups, as well as the HPV infection of the penis.

CONCLUSIONS: HIV-infected MSM had a high prevalence of HPV infection at the anal canal; however, heterosexual HIV-infected men were also at risk for acquiring and sustaining persistent high-risk HPV types at the anal and penile site and are at risk for developing dysplasia in the future. All HIV-infected men should be recommended for routinely anal HPV screening.
