Background: Few studies have assessed the risk factors associated with nonsteroidal anti-inflammatory drugs (NSAIDs)-induced small intestinal damage.Aims: To evaluate the risk factors for NSAID-induced enteropathy in patients with rheumatoid arthritis.Methods: A cross-sectional study using capsule endoscopy was conducted. A total of 113 patients who took NSAIDs for over 3 months underwent capsule endoscopies. Endoscopic findings were scored as (0) normal, (1) red spots, (2) 1-4 erosions, (3) >4 erosions, or (4) large erosions/ulcers. Initial scores were grouped into 3 categories: No damage (0-1), mild damage (2), and severe damage (3-4), and the potential risk factors for damage development were assessed.Results: Five patients were excluded because of incomplete visualization of the entire small intestine. Fifty-two (47.2%) and 27 (25%) patients had no damage and mild damage, respectively, while the remaining 30 patients (27.8%) had severe damage and significantly decreased hemoglobin levels. In a multivariate logistic regression analysis, ages of 65 years or more (odds ratio [OR], 4.16; 95% confidence interval [CI], 1.51-11.47), proton pump inhibitor usage (OR, 5.22; 95% CI, 1.36-20.11), and histamine H-2 receptor antagonist usage (OR, 3.95; 95% CI, 1.28-12.25) were independent risk factors for severe damage.Conclusions: Elderly patients and acid suppressant users are more likely to develop severe NSAID-induced enteropathy.
