Abstract

Due to high rates of human papillomavirus (HPV) infection, the incidence of intraepithelial neoplasia and anal cancer, most studies concerning HPV in men seropositive for HIV have focused on the anal canal. Few studies have targeted the penile region in HIV‐infected men. A total of 72 men seropositive for HIV and 72 men seronegative for HIV were followed‐up for 6 months, and their penile exfoliated cells were tested for HPV DNA. There were no significant differences between the HIV‐positive and HIV‐negative men in persistence (respectively, 69.5% vs. 66.9%), clearance (respectively, 15.3% vs. 23.1%), and those men never infected with HPV during the four follow‐up visits (15.2% for HIV‐positive vs. 20%for HIV‐negative). High‐risk HPV types were detected more frequently in penile smears from men infected with HIV, while, in HIV‐seronegative men, the low‐risk HPV types were more abundant (P = 0.001). Multiple infections with both high‐ and low‐risk HPV types were significantly more frequent in HIV‐seropositive compared to those who were HIV‐seronegative (P = 0.0004). The attendance rates at follow‐up visits were 86%, 78%, and 58% in months 1, 2, and 6, respectively, for men infected with HIV and 93%, 72%, and 60% for the HIV‐negative group. It is concluded that HIV infection can be considered a risk factor for clearance and persistence of HPV. Multiple infections with different types of HPV including high‐risk HPVs are frequent in men who are infected with HIV. J. Med. Virol. 83:127–131, 2011. © 2010 Wiley‐Liss, Inc.
