    Abstract:
    BACKGROUND: Studies have shown that 1-week triple therapy consisting of a proton pump inhibitor, amoxycillin and clarithromycin may cure Helicobacter pylori infection in the majority of patients. AIM: To establish whether pantoprazole plus amoxycillin in association with either azithromycin or clarithromycin is useful in curing H. pylori infection in patients with a duodenal ulcer. METHODS: One hundred and ten patients with active duodenal ulcers and H. pylori infection were treated with pantoprazole (days 1-7, 40 mg b.d.; days 8-28 40 mg o.d.) plus amoxycillin 1 g b.d. for the first 7 days. Patients were randomly assigned to receive either azithromycin 500 mg o.d. for the first 6 days (PAAz group; n=55) or clarithromycin 500 mg b.d. for the first 7 days of treatment (PAC group; n=55). H. pylori status was determined by urease test and histology before the treatment, and again 4 weeks after cessation of any medication. RESULTS: One hundred and three patients completed the study. H. pylori infection was eradicated in 78% (39/50) of patients in the PAAz group (ITT analysis: 71%, 95% CI: 61-83%) vs. 81% (43/53) of patients in the PAC group (ITT analysis: 78%, 95% CI: 69-90%) (N.S.). All ulcers had healed. CONCLUSION: Our study shows that 1-week triple therapy with pantoprazole, amoxycillin and either azithromycin or clarithromycin is not satisfactory (<80% ITT H. pylori eradication rate).
