摘要BACKGROUND & AIMS: There is no effective treatment for aspirin-induced small bowel ulcer bleeding. We performed a double-blind, randomized, placebo-controlled trial to determine whether misoprostol can heal small bowel ulcers in patients with small bowel bleeding who require continuous aspirin therapy.
METHODS: We performed a prospective study of 84 aspirin users with small bowel bleeding who required continued aspirin therapy in Hong Kong and Japan. Patients with small bowel ulcers or multiple erosions, detected by capsule endoscopy, were randomly assigned to groups that received either misoprostol (200 mg, 4 times daily; n = 42) or placebo (n = 42) for 8 weeks. All patients continued taking aspirin (100 mg, once daily). The primary end point was complete ulcer healing at follow-up capsule endoscopy. Secondary end points included changes in hemoglobin level and number of ulcer/erosions from baseline.
RESULTS: Complete healing of small bowel ulcers was observed in 12 patients in the misoprostol group (28.6%; 95% CI, 14.9%-42.2%) and 4 patients in the placebo group (9.5%; 95% CI, 0.6%-18.4%), for a difference in proportion of 19.0% (95% CI, 2.8%-35.3%; P = .026). The misoprostol group had a significantly greater mean increase in hemoglobin than the placebo group (mean difference, 0.70 mg/dL; 95% CI, 0.05-1.36; P = .035). The reduction in medium number of ulcers or erosions was significantly greater in the misoprostol group (from 6.5 [range, 1-85] to 2 [range, 0-25]) than in the placebo group (from 7 [range, 1-29] to 4 [range, 0-19] (P = .005).
CONCLUSIONS: In a double-blind, randomized, placebo-controlled trial, we found misoprostol to be superior to placebo in promoting healing of small bowel ulcers among aspirin users complicated by small bowel ulcer bleeding who require continuous aspirin therapy. However, use of misoprostol alone would provide only limited protection against aspirin on the small bowel. ClinicalTrials.gov ID NCT01998776.
