Esomeprazole alone compared with esomeprazole plus aspirin for the treatment of aspirin-related peptic ulcers

Abstract

Background: Aspirin-related peptic ulcers are a common disorder. However, whether or not aspirin should be continued during treatment for aspirin-related ulcers remains unclear.

Aims: To compare esomeprazole alone with esomeprazole plus aspirin in the treatment of aspirin-related peptic ulcers and to investigate the independent factors associated with the failure of ulcer healing.

Methods: From January 2008 to July 2011, patients with aspirin-related peptic ulcers were randomized to receive esomeprazole (40 mg per day) alone or esomeprazole (40 mg per day) plus aspirin (100 mg per day) for 8 weeks. The subjects with Helicobacter pylori infection were treated with standard triple therapy. Follow-up endoscopy was carried out at the end of the 8th week. The primary end point was the healing of peptic ulcers.

Results: In all, 178 patients (89 receiving esomeprazole alone and 89 receiving esomeprazole plus aspirin) were enrolled and underwent follow-up endoscopy. The healing rate of ulcers by modified intention-to-treat analysis was 82.5% (95% confidence interval (CI), 74.2-90.8%) among patients treated with esomeprazole alone and 81.5% (95% CI, 73.0-90.0%) among patients treated with esomeprazole plus aspirin (difference, 1.0%; 95% CI, -11.2 to 12.6%). The per-protocol analysis yielded similar results (healing rate: 83.1% vs. 83.8%, respectively; difference, 0.7%; 95% CI, -11.2 to 12.6%). Multivariate analysis disclosed that use of steroids during treatment (odds ratio: 5.6; 95% CI, 1.1-27.7%) was the only independent factor associated with the failure of ulcer healing.

Conclusions: The observed ulcer healing rates were comparable in the esomeprazole and esomeprazole-plus-aspirin groups, but the wide CIs do not rule out clinically meaningful differences of more than 10%.
