Detaljeret beskrivelse
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.
Intervention and Randomization: Eligible participants will be randomized into one of two groups:
- Group A: 14-day bismuth-vonoprazan triple therapy.
- Group B: 14-day vonoprazan-based dual therapy (without bismuth).
