Sammanfattning
The incidence of sexually transmitted infections (STI) by Chlamydia trachomatis among men who have sex with men (MSM) has increased dramatically the last decade. To investigate the occurrence and characteristics of this infection in a MSM population attending a gay health clinic, a retrospective investigation of the files of all Chlamydia positive patients at Venhälsan during 2007 was undertaken. Of 1742 patients tested 13,3% (234) were positive at one or more sites. The prevalence of positive tests was 1,7 % (26) in the pharynx, 9,3% (155) in the rectum and 5,4% (94) in the urethra/ urine. Symptoms were reported by 12%, 21% and 54% respectively from these 3 sites by the infected individuals. Infection only in the pharynx occurred in 5% of the Chlamydia patients tested in pharynx. Twenty-two per cent of the Chlamydia patients were HIV-positive. Contact tracing was the reason for testing in 29%. In this group there was an overrepresentation of infections in the pharynx and in the pharynx in combination with rectum. The majority of Chlamydia infections are asymptomatic particularly in the pharynx and rectum providing a reservoir of the microorganism. The natural course of pharyngeal Chlamydia is unknown and specimens should be taken from all three sites when a patient is suspected to have any Chlamydia infection. Contact tracing is an important tool in finding these often asymptomatic infections.
