Abstract
Objective To estimate the effectiveness and safety of triple therapy containing berberine, amoxicillin, and rabeprazole in the eradication of Helicobacter pylori ( H. pylori ) . Methods This prospective, randomized controlled, open‐label, noninferiority trial included treatment‐naive patients with H. pylori infection who were randomly allocated at a ratio of 1:1 into the berberine triple therapy group (berberine hydrochloride 300 mg thrice daily, amoxicillin 1 g twice daily, and rabeprazole 10 mg twice daily) or standard bismuth‐containing quadruple therapy group (amoxicillin 1 g twice daily, rabeprazole 10 mg twice daily, clarithromycin 500 mg twice daily, and bismuth tartrate 200 mg twice daily) for 14 days. Negative 13 C/ 14 C‐urea breath test at 4 weeks after completion of the therapy was regarded as successful eradication. Results Altogether 262 and 262 patients received berberine triple therapy and bismuth‐containing quadruple therapy, respectively. Both intention‐to‐treat (79.8% vs 80.9%, P = 0.742) and per‐protocol analyses (83.6% and 85.1%, P = 0.636) showed comparable eradication rate between the two groups, indicating a noninferior eradication rate (the lower limit of the 95% confidence interval over −10% [−7.9% and −7.87%, respectively]). Adverse events more commonly occurred in the bismuth‐containing quadruple‐therapy group (8.8% vs 16.0%, P = 0.012), while patient compliance and symptom improvement of the two regimens were comparable. Conclusion Triple therapy containing berberine, amoxicillin and rabeprazole is noninferior to bismuth‐containing quadruple therapy in the initial treatment for H. pylori eradication.
