  ABSTRACT: Aim: To investigate the factors related to the effect of eradication therapy with vonoprazan for Helicobacter pylori (H. pylori). Methods: We retrospectively reviewed medical records of H. pylori-positive patients who received first-line (40 mg vonoprazan/60 mg lansoprazole or 20 mg rabeprazole, 1500 mg amoxicillin, 400 mg clarithromycin, all 2/day for 7 days) (n = 4118). H. pylori eradication was assessed by the 13C-urea breath test with success defined as a result of H. pylori eradication therapy using vonoprazan was more effective than standard triple therapy with proton pump inhibitor. Gastric mucosal atrophy was associated with treatment success.
