Gonococcal Conjunctivitis in Adults: Case Report and Retrospective Review of Cases in Alberta, Canada, 2000-2016.

Abstract

A case of gonococcal conjunctivitis (GC) prompted us to review the reported cases and treatment regimens of GC in Alberta, Canada. Gonococcal cases reported from 2000 to 2016 were extracted from the provincial sexually transmitted infection reporting database. The diagnosis of GC was based on a positive culture and/or nucleic acid amplification test from the eye. A total of 45 cases of GC were reported in adults. Three quarters (75.6%; n = 34) of the cases were diagnosed using culture, 57.8% (n = 26) of cases were among men, and 55.5% (n = 25) were diagnosed since 2014. Very few (13.3%; n = 6) of the cases were treated according to current Canadian Guidelines on Sexually Transmitted Infections, using 2 g of ceftriaxone in combination with azithromycin or doxycycline. Results of test of cures were available for 15.6% (n = 7) of the cases and occurred within 10 to 79 days (median = 26 days) after treatment; all were negative. Gonococcal conjunctivitis was relatively uncommon in our region, but given its potential for severe manifestations and sequelae coupled with the rising rates of gonorrhea; it remains important to consider this diagnosis in sexually active individuals presenting with purulent conjunctivitis. Additional studies are needed to inform treatment recommendations and to evaluate outcomes of infection.
