The purpose of this study was to compare the performance of different regimens on Helicobacter pylori (H. Pylori) eradication and duodenal ulcer recurrence. During a four-week period, 59 patients with duodenal ulcers who were positive for H. pylori infection were randomly treated with one of three regimens. Seventeen patients were treated with ranitidine, 19 with colloidal bismuth subcitrate (CBS), and 23 with triple therapy (CBS, tetracycline and metronidazole). Forty-six patients with healed ulcers after treatment received follow-up for six months without maintenance therapy. The recurrence rates of duodenal ulcers confirmed by endoscopy in these three groups were 64%, 33% and 0% at the third month, and 73%, 67% and 5% at the sixth month, respectively. In the ranitidine therapy group, H. pylori infection was still present at the final follow-up. In the CBS therapy group, H. pylori was suppressed initially, but recurred in all cases. In the triple therapy group, there was only one case in which H. pylori infection persisted and where ulcer recurrence occurred after 3.5 months. The remaining cases were all H. pylori negative and had no recurrence of duodenal ulcers during the six months of follow-up. Overall, 19/27 (70%) patients positive for H. pylori had a recurrence of duodenal ulcers, while none of the 19 patients who were negative for H. pylori had a recurrence of ulcers at the sixth month. This study shows that triple therapy is more effective than the other two regimens in the eradication of H. pylori and in reducing the recurrence of ulcers. H. pylori may play a role in the recurrence of the duodenal ulcer.
