title: Lymphogranuloma venereum is rare in Australian community-based samples of men who have sex with men.
abstract: Lymphogranuloma venereum (LGV) typing was performed on chlamydia-positive samples obtained in Sydney, Australia, between 2005 and 2007, from community-based cohorts of predominantly asymptomatic HIV-infected and -uninfected men who have sex with men. The number of chlamydia tests and follow-up for each cohort were as follows: 2082 (90.2% of eligible visits) over 2005.1 person-years (PY) of follow-up in the HIV-uninfected cohort; and 521 (70.8% of eligible visits) over 320.2 PY of follow-up in the HIV-infected cohort. One case of rectal LGV in a symptomatic HIV-infected participant was identified among 64 Chlamydia trachomatis infections, giving an LGV incidence in the HIV-infected cohort of 0.3 per 100 PY, 95% Confidence Interval 0.008-1.7. Routine LGV typing of chlamydia infections in asymptomatic Australian men who have sex with men does not appear justified.
