Sexually transmitted infections

We evaluated the prevalence of lymphogranuloma venereum (LGV) in anorectal Chlamydia trachomatis-positive French men who have sex with men (MSM) using pre-exposure prophylaxis (PrEP) for HIV. Here, we describe the clinical, biological and behavioural characteristics of these patients. ⋯ LGV was diagnosed in 18.7% of anorectal C. trachomatis-positive specimens from French MSM using PrEP. LGV testing should be carried out for MSM diagnosed with chlamydia and with a large number of sexual partners, high-risk practices and anorectal symptoms. These patients should be presumptively treated as having LGV. This is the first surveillance study of LGV among MSM PrEP users and monitoring should continue.
