title: The prevalence of duodenal lesions in patients with rheumatic diseases on chronic aspirin therapy.
abstract: Peroral endoscopy was performed in 56 patients with rheumatic disease who had been taking 8 or more aspirin tablets daily for more than 3 months yet who had no major gastrointestinal symptoms or history of peptic ulcer disease. Duodenal mucosal lesions were observed in 16 patients; 15 (27%) had erythema, 7 (13%) had erosions, and 2 (4%) had ulcers. The prevalence of duodenal lesions was the same in patients taking regular, buffered, or enteric-coated aspirin preparations. Patients with duodenal lesions were more likely to have associated gastric lesions.
