Overview

INTRODUCTION:The study aimed to compare the efficacies and safety of 14-day hybrid therapy, 14-day high-dose dual therapy, and 10-day bismuth quadruple therapy in the first-line treatment of Helicobacter pylori infections.METHODS:In this multicenter, open-label, randomized trial, we recruited adult H. pylori-infected patients from 9 centers in Taiwan. Subjects were randomly assigned (1:1:1) to 14-day hybrid therapy, 14-day high-dose dual therapy, or 10-day bismuth quadruple therapy. Eradication status was determined by the 13C-urea breath test. The primary outcome was the eradication rate of H. pylori assessed in the intention-to-treat population.RESULTS:Between August 1, 2018, and December 2021, 918 patients were randomly assigned in this study. The intention-to-treat eradication rates were 91.5% (280/306; 95% confidence interval [CI] 88.4%-94.6%) for 14-day hybrid therapy, 83.3% (255/306; 95% CI 87.8%-95.0%) for 14-day high-dose dual therapy, and 90.2% (276/306; 95% CI 87.8%-95.0%) for 10-day bismuth quadruple therapy. Both hybrid therapy (difference 8.2%; 95% CI 4.5%-11.9%; P = 0.002) and bismuth quadruple therapy (difference 6.9%; 95% CI 1.6%-12.2%; P = 0.012) were superior to high-dose dual therapy and were similar to one another. The frequency of adverse events was 27% (81/303) with 14-day hybrid therapy, 13% (40/305) with 14-day high-dose dual therapy, and 32% (96/303) with 10-day bismuth quadruple therapy. Patients receiving high-dose dual therapy had the fewest adverse events (both P < 0.001).DISCUSSION:Fourteen-day hybrid therapy and 10-day bismuth quadruple therapy are more effective than 14-day high-dose dual therapy in the first-line treatment of H. pylori infection in Taiwan. However, high-dose dual therapy has fewer adverse effects than hybrid bismuth quadruple therapies.
