Concordance of Penile and Oral Human Papillomavirus Infections Among Men in the United States.

ABSTRACT: This study examined the concordance of penile and oral human papillomavirus (HPV) infections in the United States. A total of 1683 men aged 18-59 years who participated in the 2013-2014 National Health and Nutrition Examination Survey and had results of oral and penile HPV DNA testing were examined. The prevalence of any HPV genotype was 45.3% on the penis, 11.2% in the oral cavity, and 8.8% at both sites. The prevalence of HPV in the oral cavity was higher among those with than among those without penile HPV infection (19.3% vs 4.4%; prevalence ratio, 4.37 [95% confidence interval, 2.66-7.16]). The prevalence of ?1 genotype-concordant HPV infection was 3.2% and was associated with sexual behavior, independent of demographic characteristics and smoking status. Sexual behavior may partly explain the observed association between penile and oral HPV infections.

Project description:BackgroundTo date, the microbiota of the human penis has been studied mostly in connection with circumcision, HIV risk and female partner bacterial vaginosis (BV). These studies have shown that male circumcision reduces penile anaerobic bacteria, that greater abundance of penile anaerobic bacteria is correlated with increased cytokine levels and greater risk of HIV infection, and that the penile microbiota is an important harbour for BV-associated bacteria. While circumcision has been shown to significantly reduce the risk of acquiring human papillomavirus (HPV) infection, the relationship of the penile microbiota with HPV is still unknown. In this study, we examined the penile microbiota of HPV-infected men as well as the impact of HIV status.ResultsThe penile skin microbiota of 238 men from Cape Town (South Africa) were profiled using Illumina sequencing of the V3-V4 hypervariable regions of the 16S rRNA gene. Corynebacterium and Prevotella were found to be the most abundant genera. Six distinct community state types (CSTs) were identified. CST-1, dominated by Corynebacterium, corresponded to less infections with high-risk HPV (HR-HPV) relative to CSTs 2-6. Men in CST-5 had greater relative abundances of Prevotella, Clostridiales, and Porphyromonas and a lower relative abundance of Corynebacterium. Moreover, they were significantly more likely to have HPV or HR-HPV infections than men in CST-1. Using a machine learning approach, we identified greater relative abundances of the anaerobic BV-associated bacteria (Prevotella, Peptinophilus, and Dialister) and lower relative abundance of Corynebacterium in HR-HPV-infected men compared to HR-HPV-uninfected men. No association was observed between HIV and CST, although the penile microbiota of HIV-infected men had greater relative abundances of Staphylococcus compared to HIV-uninfected men.ConclusionsWe found significant differences in the penile microbiota composition of men with and without HPV and HIV infections. HIV and HR-HPV infections were strongly associated with greater relative abundances of Staphylococcus and BV-associated bacterial taxa (notably Prevotella, Peptinophilus and Dialister), respectively. It is possible that these taxa could increase susceptibility to HIV and HR-HPV acquisition, in addition to creating conditions in which infections persist. Further longitudinal studies are required to establish causal relationships and to determine the extent of the effect.
