Risk factors, prevalence, and site concordance of human papillomavirus in high-risk Greek men.

The aim of this study was to determine the risk factors, genotype-specific prevalence, and concordance of human papillomavirus (HPV) infections at three anatomical sites in a cohort of high-risk Greek men. Patients were recruited from sexually transmitted infection and HIV clinics in Athens. Samples were obtained from oral, penile, and anal sites of 294 study participants and HPV testing was performed on 882 samples using next-generation sequencing. Patients also completed a questionnaire assessing risk factors for infection. The mean age of the participants was 33.1, 30% identified as men who have sex with men (MSM), and 21% were HIV positive. The prevalence of HPV was 49%; it was the highest at anal sites (33%) compared with 23% at penile sites (P=0.008) and 4% at oral sites (P
