Pilot study of pharyngeal Chlamydia trachomatis in HIV-positive and HIV-negative men who have sex with men

Keshinie Samarasekara, Colin Fitzpatrick, Fionnuala Finnerty, Daniel Richardson Pharyngeal chlamydia is poorly understood in men who have sex with men (MSM). We reviewed cases of pharyngeal chlamydia in MSM during 2019. The prevalence of pharyngeal chlamydia was 75/6613 (1.13%; 95% confidence interval (CI) = 0.9–1.14). Four (5%) reported sore throat and 20 (26%) were HIV+. MSM also had concomitant infection: rectal chlamydia [39 (52%)], urethral chlamydia [12 (16%)], early syphilis [2 (3%)] and gonorrhoea [14 (19%)]. HIV-positive MSM with pharyngeal chlamydia were older (P = 0.02) and more likely to have had previous syphilis (odds ratio = 4.9; 95% CI = 1.6–14.7; P = 0.005). Further research is needed to explore the characteristics of pharyngeal chlamydia.
