Influence of age and CD4+ T cell counts on the prevalence of genital human papillomavirus infection among HIV-seropositive men who have sex with men in Taiwan

This study aimed to examine the baseline prevalence of genital human papillomavirus (HPV) infection among human immunodeficiency virus (HIV)-seropositive men who have sex with men in Taiwan and to determine the association of age and CD4+ T cell counts with HPV infection. In 2010, 305 men who have sex with men infected with HIV and 100 HIV-seronegative men who have sex with men were recruited. Genital swabs were collected and 37 HPV genotypes were detected using linear array HPV genotyping. HPV infection was present in 45.3% of the patients infected with HIV and in 18% of the HIV-negative subjects (P35 compared with that for those aged
