OBJECTIVE: High-risk (HR) human papillomavirus (HPV) is one of the major causes for most anal and penile cancers and oropharyngeal cancers in men, and vaccination against HPV is recommended for the prevention of these cancers. Data on HPV infection in Chinese men is still limited, which requires further investigation to guide vaccine development and assess the effectiveness of HPV vaccines. We thus studied the HR-HPV genotype distribution in HPV-infected men in Northern China.
PATIENTS AND METHODS: Genital specimens were obtained from male patients (≥18 years old) at the clinic for sexually transmitted infections of the Shandong Provincial Hospital between January 2016 and December 2018. Samples were analyzed for 15 HR-HPV genotypes, and 2 low-risk HPV (LR-HPV) genotypes using a multiplex real-time quantitive polymerase chain reaction (qPCR) assay.
RESULTS: Of 1,163 participants enrolled, 426 patients were diagnosed as verruca acuminata (CA) and 737 were asymptomatic men. The overall prevalence of HPV infection was 42% (489/1,163), and 27.4% (319/1,163) were positive for HR-HPV. HPV 16 (5.2%, 61/1,163) was the most common HR genotype overall, followed by HPV 52 (4.6%, 54/1,163), 51 (4.3%, 50/1,163), 18 (4.1%, 48/1,163), and 39 (4.0%, 47/1,163). Genotypes 16, 52, 39, 51, and 18 were most prevalent in CA patients, and 16, 51, 18, 59, and 39 in asymptomatic men. Prevalence of genotypes 31, 33, and 45 covered by the 9-valent HPV prophylactic vaccine was low in the assessed region.
CONCLUSIONS: HPV 16, 52, 51, 18, 39, and 59 were the most common HR genotypes detected in men in Northern China. Importantly, HPV 39, 51, and 59 are not currently covered by either the 4-valent or 9-valent HPV vaccines.
