To determine whether an association exists between relapse in inflammatory bowel disease and use of nonsteroidal anti-inflammatory drugs (NSAIDs), a retrospective records reviewwas conducted of patients with Crohn’ s disease, ulcerative colitis, or indeterminate colitis examined at an outpatient tertiary care center between July 17, 2000, and November 1,2001. Extracted data collected during the patient’ s last visit included medication use, maintenance therapy, disease activity, and smoking status. Use of NSAIDs was defined as a daily dose or more of any type the month before relapse. Of 60 patients (22, relapse; 38, remission), 9 (41% ) in relapse and 10 (26% ) in remission used NSAIDs. Maintenance therapy varied from 68% (relapse) to 92% (remission). The adjusted odds ratio between medication use and relapse was 6.31 (95% confidence interval, 1.16-34.38; P = .03). Use of NSAIDs was associated with relapse. A prospective cohort study that corrects for maintenance therapy is needed to evaluate this relationship.
