Does eradication of Helicobacter pylori alone heal duodenal ulcers?

Abstract

Bakcground:

Eradication of Helicobacter pylori infection prevents duodenal ulcer (DU) relapse, but it remains uncertain whether eradication of H. pylori alone heals duodenal ulceration.

Aim:

To test the hypothesis that eradication of H. pylori infection is accompanied by healing of duodenal ulcer.

Methods:

A total of 115 consecutive patients with endoscopically confirmed H. pylori-infected duodenal ulcer were randomly assigned to one of two groups. Group BTC patients received a 1-week course of colloidal bismuth subcitrate 220 mg b.d., tinidazole 500 mg b.d., clarithromycin 250 mg b.d. Group OBTC patients received omeprazole 20 mg daily for 4 weeks with the BTC regimen during the first week. Endoscopy with antral biopsies and ¹³C-urea breath test (UBT) were performed before and 4 weeks after completion of the 7-day triple or quadruple therapy.

Results:

Eight patients dropped out (four in BTC and four in OBTC). Duodenal ulcer healing rates on an intention-to-treat basis in BTC and OBTC were 86% (95% CI: 77–95%) and 90% (95% CI: 82–98%), respectively. The eradication rates of H. pylori on an intention-to-treat basis in BTC and OBTC were 88% (95% CI: 79–96%) and 91% (95% CI: 84–99%), respectively. There were no statistically significant differences in ulcer healing rates and eradication rates between these two groups (P > 0.05). Epigastric pain resolved more rapidly in patients assigned to OBTC compared with those assigned to BTC. Both of the two regimens were well tolerated with only minor side-effects (3% of the 115 patients) and the compliance was good.

Conclusions:

BTC is a very effective H. pylori eradication regimen. Almost all duodenal ulcers heal spontaneously after cure of H. pylori infection using a 1-week low-dose bismuth-based triple therapy. Treating duodenal ulcer with simultaneous administration of omeprazole achieves ulcer pain relief more rapidly.
