High diversity of alpha, beta and gamma human papillomaviruses in genital samples from HIV-negative and HIV-positive heterosexual South African men.


ABSTRACT:

Background

This study investigated the prevalence of HPVs in heterosexual South African men and the impact of HIV co-infection.

Methods

HPV was detected in penile swabs from 195 HIV-infected and 140 HIV-uninfected men using PCR with FAP59/64 primers and Roche Linear Array HPV genotyping (LA). Genotyping of FAP positive specimens was achieved by high-throughput sequencing of amplicons.

Results

HPV was detected by FAP PCR and LA in 79% (266/335) of the men. Men with HIV co-infection and men with HIV infected sexual partners had a significantly (p<0.0001) higher HPV infection risk (adjusted odds ratio 4.0 (2.1-8.2) and 3.7 (2.1-6.7), respectively). LA genotyping and 454 sequencing of 218 FAP positive specimens detected 45 known ?-HPV types, 45 ?-HPV types (34 known, 10 putative and 1 novel putative), and 91 ?-HPV types (26 known, 51 putative and 14 novel putative). Alpha, beta and gamma types were detected in 89.8%, 51.4% and 62.4% of the 218 men with HPV-62, HPV-5 and HPV-121 most common in each genus, respectively.

Conclusion

A great diversity of known and novel alpha, beta and gamma HPV types were detected with higher prevalence in HIV co-infected men and unknown associations, if any, with genital lesions and cancers.
