Prevalence and genotype distribution of high-risk human papillomavirus (HR HPV) in male genital samples of Osijek-Baranja County.

This is a first cross-sectional study on the prevalence and distribution of HPV infection in asymptomatic, heterosexual men from Osijek-Baranja County, Croatia. Between 2009 and 2011, 330 men tested for sexually transmitted diseases (STDs) were recruited. Their genital swabs were tested for high-risk HPV (HR HPV) infection by the AMPLICOR HPV test and further genotyped by the Linear Array HPV Genotyping Test (both by Roche). Infection with a single HR HPV was detected in almost one third of men (39%) whereas multiple HPV types, in more than a half of HR HPV-positive men (61%). The highest HR HPV prevalence was detected in those younger than 20 (37.5%) and lowest in 31-35 year old men (27.8%). The most common genotypes were HPV 6 (24%), 16 (17.8%), 51 (9%), 52 (6%), 35, 55, 66, 84 (each 5%), 31, 62 (each 4%), 39, 58, 59, 83 (each 2.5%), and finally 56, 18, 53, and 54 (each 1.3%). Having more than one sexual partner per year was significantly associated with HR HPV infection in age group between 26 and 30 years (p = 0.001). Due to the high prevalence of HR HPV infection in men of this County and its risk of transmission to women, we recommend more public awareness about this particular STD and initiating vaccination programs of young men and women.
