AIM: To compare the eradicating capacity of two different antibiotic-lansoprazole combinations (amoxycillin vs. standard triple therapy) with that of lansoprazole alone in Helicobacter pylori-positive duodenal ulcer patients. METHODS:Ninety-six out-patients with H. pylori-positive duodenal ulcer were randomly assigned to receive one of the following three antiulcer regimens: (1) lansoprazole 30 mg b.d. for 4 weeks plus amoxycillin 1 g t.d.s. during the last 2 weeks; or (2) lansoprazole 30 mg once daily for 4 weeks plus classical triple therapy (tripotassium dicitratobismuthate 240 mg b.d., amoxycillin 1 g t.d.s. and tinidazole 500 mg b.d.) for the last 2 weeks; or (3) lansoprazole 30 mg once daily for 4 weeks. Endoscopy was repeated at the end of treatment and 1 month later. A rapid urease test and histology were used to determine H. pylori status. RESULTS:Duodenal ulcer healing rates at 4 weeks were 96% after both lansoprazole with amoxycillin, and lansoprazole with triple therapy, and 97% after lansoprazole alone. Eradication of H. pylori was significantly better with lansoprazole with triple therapy than with either lansoprazole with amoxycillin or lansoprazole alone (90% vs. 55% vs. 3%, respectively). CONCLUSION: Classical triple therapy combined with lansoprazole is significantly more effective than the lansoprazole with amoxycillin combination for the eradication of H. pylori in duodenal ulcer patients pre-treated withlansoprazole.

METHODS: Ninety-six out-patients with H. pylori-positive duodenal ulcer were randomly assigned to receive one of the following three antiulcer regimens: (1) lansoprazole 30 mg b.d. for 4 weeks plus amoxycillin 1 g t.d.s. during the last 2 weeks; or (2) lansoprazole 30 mg once daily for 4 weeks plus classical triple therapy (tripotassium dicitratobismuthate 240 mg b.d., amoxycillin 1 g t.d.s. and tinidazole 500 mg b.d.) for the last 2 weeks; or (3) lansoprazole 30 mg once daily for 4 weeks.
