Abstract
Forty-nine patients with Helicobacter pylori (Hp)-positive gastric ulcer (GU) and 39 patients with Hp-positive duodenal ulcer (DU) were studied. Before the trial and every 3 or 4 weeks, phenol red dye spraying endoscopy, the rapid urease test, biopsy specimen histology, and culture were performed to assess the ulcer stage and to detect Hp. Patients were divided into three groups: group I received lansoprazole 30 mg/d; Group II received dual therapy of lansoprazole 30 mg/day and amoxicillin (AMPC) 1 g/day or clarithromycin (CAM) 400 mg/day; and Group III received combination therapy of lansoprazole 30 mg/day, AMPC 1 g/day, or CAM 400 mg/day, and metronidazole 500 mg/day. Patients with GU received lansoprazole for 8 weeks and patients with DU received lansoprazole for 6 weeks. The other agents were administered for 2 weeks at the beginning of the trial. There were no differences in ulcer healing among the three treatment groups in patients with GU or DU, but there were significant differences in the eradication of Hp. No side effects were observed in any of the patients. We conclude that combination therapy is likely to be most effective and is harmless for Hp-persistent patients with peptic ulcer.
