title: Oral human papillomavirus infection in men who have sex with men with anal squamous intraepithelial lesions.
abstract: Little is known about the association between oral and anogenital human papillomavirus (HPV) infections.
  
  
  
  Oral and anal samples from 66 men who have sex with men with a history of HPV-related anogenital squamous intraepithelial lesions were analyzed using polymerase chain reaction (PCR), and typed for 38 HPV types.
  
  
  
  Prevalence of oral HPV infection was 30%, versus 82% for anal infection. Prevalence of oral and anal high-risk HPV infection was 11% and 64%, respectively. Concurrent oral-anal any-type HPV infection was found in 26% of participants, whereas concordant type-specific HPV prevalence was 5%. In multivariate analysis, number of partners from whom the participant received oral-penile sex and number of partners on whom the participant performed oral-penile sex were associated with oral HPV infection.
  
  
  
  Oral HPV prevalence in this cohort is high, however, concordant type-specific oral-anal HPV infection was rare. Increased risk of oral HPV infection was associated with oral-penile sex. © 2015 Wiley Periodicals, Inc. Head Neck 38: E399-E405, 2016.
