ABSTRACTTrichomonas vaginalisinfection is highly prevalent worldwide and is associated with urethritis, prostatitis, and urethral strictures in men. However, the natural history and importance of T. vaginalisin men are poorly understood, in part because of difficulties in diagnosing infection. Traditional detection methods rely on culture and wet-mount microscopy, which can be insensitive and time consuming. Urethral swabs are commonly used to detect T. vaginalisin men, but discomfort from specimen collection is a barrier to large studies. One thousand two hundred twenty-five Malawian men attending sexually transmitted disease and dermatology clinics were enrolled in this cross-sectional study to validate detection by urine-based PCR-enzyme-linked immunosorbent assay (ELISA) with urine and urethral swab culture as the reference standard. This assay for detection of amplified T. vaginalisDNA in first-catch urine (=30 ml) performed with a sensitivity of 92.7%, a specificity of 88.6%, and an adjusted specificity of 95.2% compared to culture of urethral swabs or urine sediment. For clinical research settings in which urethral swabs are not available and culture is not feasible, the urine-based PCR-ELISA may be useful for detection of trichomoniasis in men. |
