Molecular Detection and Typing of Human Papillomavirus in Men from Northwestern Mexico

Abstract

Background: A few studies of Human Papillomavirus (HPV) distribution and frequency have shown a real context of infection in men. The study aimed to know the HPV types distribution in men from Northwestern Mexico, in general, per age and year.

Methods: A total of 1,769 males were recruited from 5 years (2011-2015), from an HPV PCR testing laboratory service. Penile scraps from urethral meatus and coronal sulcus were taken for DNA isolation. There were detected 32 high and low-risk HPV types by HPV Type 3.5 LCD-Array system.

Results: A high frequency of HPV-6 and HPV-66 and a reduced frequency of HPV-18 and HPV-11 was detected. Young men had a high risk of HPV infection regarding men aged 40 years and older. The theoretical coverage for the HPV vaccine in men was calculated, where the bivalent vaccine showed coverage of 21.66% in high-risk HPV positive cases.

Conclusion: The men from Northwestern Mexico have a different distribution of high and low-risk HPV types and high risk of HPV infection in younger men, with a theoretical coverage for HPV bivalent vaccine of 1 of 10 positive men for any HPV type.
