OBJECTIVES: To examine lymphogranuloma venereum (LGV) trends over time among men who have sex with men (MSM) visiting the Amsterdam sexually transmitted infection (STI) clinic; to investigate anal LGV symptomatology; and to examine the positivity and characteristics of anorectal and inguinal LGV.
METHODS: We included MSM consultations from whom a swab (from anorectum, bubo or an genital ulcer) was taken for Chlamydia trachomatis (Ct) screening. Anorectal swabs were taken from all MSM who reported receptive anorectal intercourse in the preceding 6 months. Ct positive samples were further tested with a pmpH PCR to identify L-genovars. Patient symptoms, clinical and anoscopic inflammatory signs, and STI co-infections were noted; Gram-stained anorectal mucosal smears were examined.
RESULTS: Between January 2005 and June 2012, 48 570 consultations among MSM were conducted. In 3628/35 650 visits, anorectal Ct infections were diagnosed, including 411 anal LGV (1.2%). Moreover, 65/1649 genital ulcer swabs were Ct positive; 10 were inguinal LGV (0.6%) Since January 2011 a significant increase in the positivity of LGV occurred (p<0.0001). 89 (27.2%) anorectal LGV cases were asymptomatic. HIV prevalence among anorectal LGV cases was significantly higher (p=0.008) than among inguinal LGV cases. STI co-morbidity in anorectal LGV cases remained invariably high during the study period.
CONCLUSIONS: Since January 2011, LGV positivity in MSM consultations in Amsterdam has risen significantly. The great majority comprise anal LGV; inguinal LGV is rare. Anal LGV is asymptomatic in a quarter of cases. In all MSM with anal Ct infections LGV should be excluded, irrespective of symptoms or inflammatory signs.
