We reviewed cases of pharyngeal chlamydia in MSM from January to December 2019. The overall prevalence of pharyngeal chlamydia was 75\/6613 (1.13%; 95% confidence interval (CI) = 0.9\u20131.14). The median number of sexual partners was three, four (5%) reported throat symptoms and 20 (26%) were HIV positive. Multi-site and concomitant infection was common: 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\u201314.7; P = 0.005). Further research is needed to explore the characteristics of pharyngeal chlamydia and benefits of increased screening for asymptomatic pharyngeal chlamydia in MSM.<\/jats:p>","DOI":"10.1071\/sh20218","type":"journal-article","created":{"date-parts":[[2021,4,26]],"date-time":"2021-04-26T23:35:54Z","timestamp":1619480154000},"page":"200-201","source":"Crossref","is-referenced-by-count":2,"title":["Pilot study of pharyngeal Chlamydia trachomatis in HIV-positive and HIV-negative men who have sex with men"],"prefix":"10.1071","volume":"18","author":[{"given":"Keshinie","family":"Samarasekara","sequence":"first","affiliation":[{"name":"ASexual Health and HIV Medicine, Brighton and Sussex University Hospitals NHS Trust, Brighton, UK."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Colin","family":"Fitzpatrick","sequence":"additional","affiliation":[{"name":"ASexual Health and HIV Medicine, Brighton and Sussex University Hospitals NHS Trust, Brighton, UK."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fionnuala","family":"Finnerty","sequence":"additional","affiliation":[{"name":"ASexual Health and HIV Medicine, Brighton and Sussex University Hospitals NHS Trust, Brighton, UK."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0955-6307","authenticated-orcid":true,"given":"Daniel","family":"Richardson","sequence":"additional","affiliation":[{"name":"ASexual Health and HIV Medicine, Brighton and Sussex University Hospitals NHS Trust, Brighton, UK."},{"name":"BSexual Health and HIV Medicine, Brighton and Sussex Medical School, Brighton, UK."},{"name":"CCorresponding author.
