Among 759 cases of proctitis diagnosed at a sexually transmitted disease clinic in Seattle, WA over 11 years, no identifiable pathogen was identified in more than half of cases, although testing for herpes simplex virus was uncommon. Abstract We analyzed microbiologic etiologies of proctitis among patients seen in an urban sexual health clinic during 2011 to 2021. Among 759 cases, 179 (24%) tested positive for Neisseria gonorrhoeae, 171 (23%) for Chlamydia trachomatis, 21 (3%) for herpes simplex virus, 30 (4%) for syphilis, and 73 (10%) for multiple pathogens; no pathogen was identified in 425 (56%).
