A pilot study on Trichomonas vaginalis in women with recurrent urinary tract infections

摘要

Background Trichomoniasis and recurrent urinary tract infections (UTIs) shared similar risk factors, age distribution and overlapping symptoms. The aim of this study was to determine the prevalence of Trichomonas vaginalis (TV) in women with recurrent UTIs, attending a urology clinic in a medical center, in order to inform screening and treatment policies. Methods Women with recurrent UTIs, defined as the presence of lower urinary tract symptoms (dysuria, frequency and urgency) and three positive urine cultures on voided urine specimens in the previous year, were enrolled prospectively from January 2013 to April 2014. Urine samples were collected for culture and tested for {TV} using immunochromatographic strip. Outpatient follow-up was arranged to diagnose any symptomatic {UTI} recurrence. Results Sixty-five women were recruited. Mean age was 57.4?±?14.3 year-old and follow-up duration was 9.5?±?4.0?months. The prevalence of {TV} was 16.9% (11/65). Eight women had {UTI} recurrence in the follow-up period. Recurrence rate did not differ in patients with and without concomitant {TV} infection. Conclusions Given the high prevalence of TV, we suggest that testing for {TV} should be considered in women with recurrent UTIs. Further larger studies are needed to evaluate the potential benefit of treating {TV} in this group of patients.
