    Abstract:
    PURPOSE: This study examined the possible relationship between peptic ulcer recurrence and the presence or absence of maintenance therapy with an H(2)-receptor antagonist performed until evaluation of Helicobacter pylori eradication. METHODS: The subjects were 483 patients with peptic ulcer (281 gastric ulcer and 202 duodenal ulcer) who were diagnosed as H. pylori positive. After receiving eradication therapy for H. pylori, patients were allocated at random to one of three different maintenance therapies: control group (no maintenance therapy), H(2)-receptor antagonist half-dose group, and H(2)-receptor antagonist full-dose group. The maintenance therapy was performed for 4 weeks until evaluation of H. pylori eradication. RESULTS: Among the 25 patients with a recurrent ulcer, 18 patients (72%) had a recurrence at the time of or before evaluation of H. pylori eradication. In the control group, the rate of ulcer recurrence occurring before evaluation of H. pylori eradication was 10.5% (14/133). This rate was significantly higher than those in the H(2)-receptor antagonist half-dose group (2.9%, 4/136) and the full-dose group (0%, 0/135). CONCLUSION: The results of this study suggest that maintenance therapy with an H(2)-receptor antagonist performed after eradication therapy until evaluation of H. pylori eradication is likely to greatly reduce the ulcer recurrence rate without affecting evaluation of H. pylori eradication.
