Abstract
To evaluate potency and safety of 14-day bismuth–furazolidone quadruple regimens and to compare efficacies of five proton pump inhibitors (PPIs) for the initial eradication of Helicobacter pylori (H. pylori), 175 eligible patients were enrolled and randomly assigned to 14-day quadruple regimens consisting of bismuth (400 mg), amoxicillin (1 g), furazolidone (100 mg), and a PPI, twice a day. PPIs used were Group A (pantoprazole capsules, 40 mg), Group B (pantoprazole tablets, 40 mg), Group C (lansoprazole, 30 mg), Group D (esomeprazole, 20 mg), and Group E (rabeprazole, 10 mg). H. pylori status was reassessed by 13C urea breath test on day 56 as the primary outcome. Gastrointestinal symptoms, parenteral side effects, compliance, and stool type were recorded simultaneously. The total eradication rates were 86.9% (152/175 [95% CI 80.9–91.5%]) and 95.6% (152/159 [91.1–98.2%]) by intention-to-treat (ITT) and per-protocol (PP) analysis. The efficacies of Group A, B, C, D, and E by ITT analysis were 91.4% (32/35 [76.9–98.2%]), 85.7% (30/35 [69.7–95.2%]), 88.6% (31/35 [73.3–96.8%]), 85.7% (30/35 [69.7–95.2%]), and 82.9% (29/35 [66.4–93.4%]) (p > 0.05). In the PP analysis, the efficacies were 97.0% (32/33), 93.8% (30/32), 93.9% (31/33), 100% (30/30), and 93.5% (29/31) (p > 0.05). Gastrointestinal symptoms and stool type were improved significantly (p < 0.05). Total side effects rate and poor compliance rate were 15.7% (25/159) and 5.0% (8/159). Fourteen-day bismuth–furazolidone quadruple regimens are of high potency and safety for the initial eradication of H. pylori. Efficacies of different PPIs and different dosages (9–32 mg omeprazole equivalents) showed no significant difference. The appropriate PPI can thus be chosen by clinicians.
