Detection of oral human papillomavirus in HIV-positive men who have sex with men 3 years after baseline: A follow up cross-sectional study

Abstract

Background: Human papillomavirus (HPV) is a causative agent in oropharyngeal squamous cell carcinoma. The natural history of oral HPV in HIV-positive men who have sex with men (MSM) is unclear. Methods: Detection of oral human papillomavirus in 173 HIV-positive MSM using oral rinse samples 3 years apart was investigated. HPV DNA was detected by polymerase chain reaction, and genotyped by Roche Linear Array. Results: Of 173 men tested in 2010, 30 had at least one HPV genotype (17%, 95% CI: 12-23), 15 at least one hr-HPV (9%, 95% CI: 5-14) and 8 had HPV 16 (5%, 95% CI: 2-9) detected. In 2013, 33 had at least one HPV genotype (19%, 95% CI: 14-26), 20 had at least one hr-HPV (12%, 95% CI: 7-17) ..
