AbstractVonoprazan (VPZ) has been shown to have superior acid-inhibitory effects compared to proton pump inhibitors (PPIs). However, there is a paucity of research examining the efficacy of vonoprazan-based bismuth quadruple therapy (VBQT) in the eradication of primary Helicobacter pylori infection. This study aimed to evaluate the effectiveness and safety of VBQT as a first-line treatment for H pylori eradication. This retrospective, real-world, single-arm study included consecutive treatment-naive patients who received VBQT (VPZ 20 mg, amoxicillin 1000 mg, clarithromycin 500 mg, bismuth potassium citrate 220 mg, all administered twice daily for 14 days) for H pylori eradication between March 1, 2021, and May 30, 2023. The study included both outpatients and inpatients. Eradication rates were assessed using 13C-urea breath tests or 14C-urea breath tests performed 4 to 6 weeks after treatment. The primary outcomes included eradication rates, adverse events, and treatment compliance. A total of 612 H pylori-infected patients were included in the study. The intention-to-treat (ITT), modified ITT (MITT), and per-protocol analyses showed H pylori eradication rates of 84.3% (95% CI: 812% to 87.1%), 95.9% (95% CI: 93.9% to 97.4%), and 96.4% (95% CI: 94.4% to 97.8%), respectively. In the ITT analysis, the adverse event rate was 12.7%, and the treatment compliance rate was 96.9%. In real-world practice, the VBQT regimen demonstrates excellent efficacy and favorable tolerability as a first-line therapy for H pylori eradication.Copyright © 2024 the Author(s).
