Trichomonas vaginalis infection: How significant is it in men presenting with recurrent or persistent symptoms of urethritis?

Persistent or recurrent non-gonococcal urethritis has been reported to affect up to 10–20% of men attending sexual health clinics. An audit was undertaken to review the management of persistent or recurrent non-gonococcal urethritis in men presenting at Whittall Street Clinic, Birmingham, UK. Detection of Trichomonas vaginalis infection was with the newly-introduced nucleic acid amplification test. A total of 43 (8%) of 533 men treated for urethritis re-attended within three months with persistent or recurrent symptoms. Chlamydia trachomatis infection was identified in 13/40 (33%), T. vaginalis in 1/27 (4%) and Mycoplasma genitalium in 6/12 (50%). These findings suggest that the prevalence of T. vaginalis infection remains low in our clinic population and may not contribute significantly to persistent or recurrent non-gonococcal urethritis.
