Optimized dual therapy for treatment-naive patients of Helicobacter pylori infection: A large-scale prospective, multicenter, open-label, randomized controlled study
Background The efficacy and safety of high-dose amoxicillin (AMX) and proton pump inhibitors (PPI) dual therapy raises much more attention in recent years. Comparative studies among the dual therapies are required to explore more suitable regimens. This study compared the efficacy, adverse events, and patient compliance of three different high-dose dual regimens in treatment-naive patients of Helicobacter pylori (H. pylori) infection. Materials and Methods The study was a prospective, multicenter, open-label, randomized controlled trial, including H. pylori-infected treatment-naive patients at 12 tertiary hospitals in China. The eligible subjects received high-dose AMX and esomeprazole (ESO) dual therapy of different regimens. They were randomly assigned to group A (ESO 20 mg plus AMX 750 mg, Qid for 14 days), group B (ESO 40 mg Bid plus AMX 1 g Tid for 14 days), or group C (ESO 20 mg plus AMX 1 g, Tid for 14 days). The eradication rates, adverse events, and patient compliance of the three groups were compared. Results Between April 2021 and January 2022, a total of 1080 subjects were screened and 945 were randomized. The eradication rates in groups A, B, and C were 88.6% (95% CI 84.5%-91.9%), 84.4% (95% CI 80.0%-88.3%), and 86.7% (95% CI 82.4%-90.2%; p = .315), respectively, based on intention-to-treat analysis; 90.3% (95% CI 86.4%-93.3%), 85.5% (95% CI 81.1%-89.2%), and 87.8% (95% CI 83.6%-91.2%; p = .197), respectively, according to modified intention-to-treat analysis; and 90.4% (95% CI 86.5%-93.5%), 85.8% (95% CI 81.4%-89.5%), and 88.3% (95% CI 84.1%-91.7%; p = .202) in per-protocol analysis. History of antibiotics use in 2 years reduced eradication effect in group B (ESO 40 mg Bid, AMX 1 g Tid). The modified intention-to-treat eradication rates were 81.4% vs 90.0% among those with or without a history of antibiotics use in group B (p = .031). The adverse event rates were 13.7%, 12.7%, and 12.1% in groups A, B, and C, respectively (p = .834). Patient compliance of the three groups was similar. Conclusions Two optimized AMX and PPI dual regimens (ESO 40 mg Bid or 20 mg Tid plus AMX 1 g Tid for 14 days) had similar efficacy, safety and compliance as compared with classical dual regimen (ESO 20 mg plus AMX 750 mg Qid for 14 days) in H. pylori-infected treatment-naive patients.
