Abstract
We evaluated the efficacy of omeprazole (OPZ) for the treatment of upper gastrointestinal (UGI) lesions in rheumatoid arthritis (RA) patients. Fourteen RA patients with H2 receptor antagonist- (H2RA-) resistant UGI lesions (1 stomal, 11 gastric, and 2 esophageal with reflux esophagitis ulcers) were treated with OPZ at 20 mg/day (study A). New untreated UGI lesions (1 stomal and 12 gastric ulcers) were treated with OPZ (study B). Three patients who showed renal dysfunction during H2RA treatment for UGI lesion were treated with OPZ (study C). Nonsteroidal antiinflammatory drugs (NSAIDs) were not discontinued. The stage of each ulcer was determined by gastrointestinal fiberscopy (GIF). In study A, during the first 8 weeks of OPZ treatment, 1 esophageal and 7 gastric ulcer patients were completely cured. Six patients showing partial response were treated further with OPZ for another 8 weeks. During this second period, 1 stomal and 3 gastric ulcer patients were completely cured, and 1 gastric and 1 esophageal ulcer patient showed only partial response. In study B, after an 8-week OPZ treatment, all except 2 patients showed complete healing. One patient developed mild eruption at 4 weeks and was shifted to H2RA. One patient showed complete healing after 4 weeks. No patient in study C showed renal dysfunction with OPZ. Our results suggest that OPZ is an effective treatment for UGI lesions in RA patients using NSAIDs.
