Symptomatic response to therapy of men with gonococcal urethritis: do all need posttreatment cultures?
Because the large majority of men with gonorrhea respond to antimicrobial therapy with the rapid disappearance of signs and symptoms, it was hypothesized that a symptomatic response to therapy would predict successful treatment. The records of 4897 men with gonorrhea, of whom 183 (3.7%) were treatment failures on days 3-7 after treatment were studied, and the clinical response to therapy with microbiologic outcome was correlated. Before therapy, 4662 men (95.2%) had dysuria and/or urethral discharge. Of the 582 men who remained symptomatic, 103 (17.7%) had a positive culture after treatment, as compared with only 78 (1.9%) of 4080 men who became asymptomatic (P less than .01). The conclusion was that men who are initially symptomatic and become asymptomatic after therapy have a small chance (one of 50) of being infected at the posttreatment visit. However, because of its very large size, this group contributed almost one-half of all treatment failures (78 of 183; 42.6%).
