STI in times of PrEP: high prevalence of chlamydia, gonorrhea, and mycoplasma at different anatomic sites in men who have sex with men in Germany.
Men who have sex with men (MSM) are disproportionally affected by sexually transmitted infections (STI). STI are often extragenital and asymptomatic. Both can delay diagnosis and treatment. Approval of HIV pre-exposure prophylaxis (PrEP) might have influenced sexual behaviour and STI-prevalence of HIV- MSM. We estimated STI-prevalence and risk factors amongst HIV- and HIV+ MSM in Germany to plan effective interventions. ⋯ We found a high STI-prevalence in MSM in Germany, especially in PrEP users, frequently being asymptomatic. As a relevant proportion of PrEP users will not use a condom, counselling and comprehensive STI screening is essential and should be low threshold and preferably free of cost. Counselling of PrEP users should also address use of party drugs.
