OBJECTIVE: The present study aimed to investigate human papillomavirus (HPV) prevalence and identify risk factors for HPV detection in urine samples among heterosexual men attending urological clinics.
MATERIALS AND METHODS: Spot urine samples including initial stream were collected from 845 participants, and the cell pellets were preserved into liquid-based cytological solution. After DNA extraction from each sample, HPV-DNA amplification and genotyping were performed using Luminex multiplex polymerase chain reaction. Participants completed a questionnaire on their age, education, smoking status, sexuality, age of sexual debut, marital status, and present history of sexually transmitted infections.
RESULTS: Data from 803 patients were included in the analysis. Overall HPV and high-risk (HR)HPV prevalence in urine samples were 6.2% and 3.1%, respectively. HPV and HR-HPV prevalences were the highest in men with urethritis, and were significantly higher than those without urethritis. HPV detection was the most common in men aged 40-49 years, although significant detection differences were not age-related. Urethritis was an independent risk factor for HPV detection from urine samples, with an odds ratio (OR) of 4.548 (95%CI; 1.802-11.476) (p = 0.001). On the other hand, a sub-analysis excluding men with urethritis demonstrated that prostate cancer was a significant risk factor for HPV detection, with OR of 2.844 (95%CI; 1.046-7.732) (p = 0.0410), whereas was not a significant risk for HR-HPV detection in urine samples.
CONCLUSION: Prostate cancer may represent a risk factor for HPV detection in the urine of men without urethritis.
REGISTRATION OF CLINICAL TRIALS: The authors did not register to Clinical Trial because this is observational and cross-sectional study.
