Abstract:
Bismuth‐containing quadruple therapy for Helicobacter pylori ( H . pylori ) eradication has a relatively high rate of side effects and high cost, thus the option of a high‐dose dual therapy with a high eradication rate and fewer adverse events is a consideration. However, studies of dual therapy are still scarce and are mostly single‐center studies with limited generalizability. Large‐scale, multicenter studies are required. Our study investigated and compared the effectiveness, adverse events, patient compliance, and costs of high‐dose dual therapy with those of bismuth‐containing quadruple therapy in H . pylori ‐infected treatment‐naive patients in a prospective, multicenter, open‐label, randomized controlled trial. Method Treatment‐naive patients infected with H . pylori were randomly assigned to receive high‐dose dual therapy (esomeprazole 20 mg 4 times daily and amoxicillin 1000 mg 3 times daily, for 14 days) or bismuth‐containing quadruple therapy (esomeprazole 20 mg, amoxicillin 1000 mg, clarithromycin 500 mg, and bismuth potassium citrate 220 mg, all twice daily for 14 days). The effectiveness, adverse events, patient compliance, and costs of both groups were compared. Results A total of 700 patients were enrolled. The high‐dose dual therapy group ( N = 350) achieved eradication rates of 89.4% (intention‐to‐treat), 90.4% (modified intention‐to‐treat), and 90.6% (per‐protocol), which were similar to rates in the bismuth‐containing quadruple therapy group ( N = 350), 84.6%, 88.0%, and 88.2%, respectively ( p 〉 0.05). The high‐dose dual therapy group had a lower rate of adverse events (12.9% vs. 28.1%, p 〈 0.001) and lower costs (¥590.2 vs. ¥723.22) compared with the quadruple therapy group, respectively. The compliance of both groups was satisfactory (97.7% high‐dose dual vs. 96.8% quadruple, p 〉 0.05). Conclusion High‐dose dual therapy for H . pylori eradication had similar efficacy and compliance, fewer adverse events, and lower costs than bismuth‐containing quadruple therapy for treatment‐naive patients.
