简要总结
This study aims to compare the efficacy and safety of a bismuth-supplemented 14-day vonoprazan-based dual therapy ( triple therapy) versus a 14-day vonoprazan-based dual therapy without bismuth for first-line H. pylori eradication. Furthermore, the investigators will investigate the impact of these eradication regimens on the gut microbiota, the development of antibiotic resistance, and changes in metabolic syndrome indicators pre- and post-treatment.
详细描述
Background: Although bismuth is not an antibiotic, it enhances antibiotic efficacy through multiple synergistic mechanisms. Currently, it remains unknown whether adding bismuth to a 14-day bismuth-vonoprazan-amoxicillin triple therapy is superior or non-inferior to the vonoprazan-amoxicillin dual therapy alone.
Objectives: This study aims to compare the efficacy and safety of a bismuth-supplemented 14-day vonoprazan-based triple therapy versus a 14-day vonoprazan-based dual therapy without bismuth for first-line H. pylori eradication.
Hypothesis: The investigators hypothesize that the efficacy of a 14-day bismuth-vonoprazan triple therapy is superior or non-inferior to that of a 14-day vonoprazan-based dual therapy without bismuth.
Methods:
Study Design: An open-label, randomized controlled trial (RCT). Participants: The investigators intend to recruit 990 treatment-naïve patients with confirmed H. pylori infection.
