Low prevalence of asymptomatic sexually transmitted infections in HIV-infected heterosexuals visiting an HIV clinic in the Netherlands.

Two-hundred and forty-five heterosexual HIV-infected patients (58% women; median age 41 years) were screened for asymptomatic sexually transmitted infections (STIs) during a routine visit at a large HIV outpatient clinic in the Netherlands. High-risk sexual behaviour was rare and STI prevalence was low: three Chlamydia trachomatis infections and one case of syphilis were diagnosed. These results suggest that, in the Netherlands, screening for STI during routine visits is currently not needed for asymptomatic heterosexual HIV-infected patients.
