    Abstract:
    OBJECTIVE: To estimate the incidence; persistence and correlates of human papillomavirus (HPV) infection and anogenital warts (AGW) among men living with human immunodeficiency virus (MLHIV). METHODS: Overall, 304 MLHIV 18 years or older were enrolled and attended follow-up visits at 6, 12, and 18 months. Clinicians examined for AGW, collected blood, and penile swabs for HPV testing (Roche Linear Array) at each visit. Time to AGW incidence or clearance was estimated by Kaplan-Meier method. Factors associated with persistent HPV infection and AGW clearance were evaluated with generalized estimating equations and Cox regression, respectively. RESULTS: Mean age of participants was 38 years (standard deviation, 8 years); 25% reported more than 1 sexual partner in the past 3 months. Most (65%) participants were on antiretroviral treatment (ART) with a median CD4 count of 445 cells/μL (interquartile range, 328-567). Prevalence of HPV infection and AGW at enrolment were 79% (224 of 283) and 12% (36 of 304), respectively. Two hundred fifty-nine men were followed up for a median (interquartile range) 1.4 years (0.5-1.7 years). Incidence of any-genital HPV infection was 2.9 (95% confidence interval, 1.5-5.5) per 100 person-years. Persistence of any-genital HPV infection was 35% (68 of 192) and was higher among MLHIV with low CD4 count (adjusted odds ratio, 3.54; 95% confidence interval, 2.07-6.05). Incidence of AGW was 1.4 per 100 person-years. Men living with human immunodeficiency virus with high CD4 count were more likely to clear AGW than those with low CD4 count (adjusted hazard ratio, 3.69; 95% confidence interval, 1.44-9.47). No associations were observed between persistent genital HPV infection, AGW clearance with enrolment ART status or duration. CONCLUSIONS: Human immunodeficiency virus-positive men have a high burden of genital HPV infection and AGW. The ART and HPV vaccine could reduce this burden.
