    Abstract:
    OBJECTIVE: To compare the efficacy of two protocols for the eradication of Helicobacter pylori infection and the healing of active duodenal ulcer: (i) ranitidine bismuth citrate (RBC) plus two antibiotics for 7 days, and (ii) the same triple therapy followed by 3 weeks of anti-secretory drug treatment. METHODS: The study comprised 102 patients with active duodenal ulcer and H. pylori infection; the patients were randomized to open treatment with either RBC 400 mg b.d. plus amoxycillin 1 g b.d. and clarithromycin 500 mg b.d. for 7 days, or the same treatment followed by 3 weeks of RBC 400 mg b.d. alone. Ulcer healing was confirmed by endoscopy. H. pylori eradication was assessed by endoscopy, rapid urease test and histology. RESULTS: The ulcer healed in 48/50 patients on RBC-based triple therapy alone (96.0%) and in 51/52 patients on triple therapy plus further anti-secretory treatment (98.1%). On an intention-to-treat basis, H. pylori had been successfully eradicated in 42/50 patients on triple therapy (84.0%) and in 44/52 patients on triple therapy plus anti-secretory treatment (84.6%), while by per protocol analysis the H. pylori eradication rates were 91.3% (42/46) and 89.8% (44/49), respectively. CONCLUSIONS: One-week triple therapy with RBC, amoxycillin and clarithromycin is highly effective in eradicating H. pylori and healing duodenal ulcers, even if not followed by anti-secretory drug treatment.
