Abstract:
Doxycycline treats and prevents several bacterial and parasitic infections and has been proposed as a possible treatment for Trichomonas vaginalis. Nested in a trial of doxycycline postexposure prophylaxis among cisgender women in Kenya, we conducted a secondary analysis of incident T. vaginalis infections. Among 224 cisgender women randomized to doxycycline postexposure prophylaxis and 225 to standard-of-care, there were 27 T. vaginalis diagnoses in the doxycycline postexposure prophylaxis group and 29 in the standard-of-care group (RR: 0.96, 95% CI: 0.54-1.73, P = .9). Understanding doxycycline postexposure prophylaxis's impact on T. vaginalis remains an important public health question that warrants further investigation.
