ABSTRACT
BACKGROUND: According to the Maastricht VI/Florence consensus report, potassium-competitive acid blockers (P-CAB) may improve Helicobacter pylori eradication treatment. MATERIALS AND METHODS: A total of 213 H. pylori treatment-naive patients aged between 18 and 70 years were treated with two regimens. The two regimens are VDT: 20 mg vonoprazan twice a day and 1 g amoxicillin three times daily and EDT: 20 mg esomeprazole four times a day and 750 mg amoxicillin four times daily. 13 C-urea breath tests were used to evaluate eradication rate 4-6 weeks after treatment. Based on propensity score matching (PSM), this retrospective study analyzed the eradication rates, adverse events (AEs), compliance, and antibiotic resistance rates in VDT and EDT groups. RESULTS: On intention-to-treat (ITT) analysis, the eradication rate in VDT group (89.0%; 95% CI 81.7-96.3) was non-inferior to that in EDT group (87.7%; 95% CI 80.1-95.3; p = 0.796). The corresponding per-protocol (PP) eradication rates were 94.1% (95% CI 88.4-99.8) and 92.8% (95% CI 86.7-98.9; p = 1.000), respectively. There were no significant between-group differences with respect to compliance or incidence of AEs. CONCLUSIONS: The efficacy and safety of 14-day VDT and EDT were comparable. Therefore, 14-day VDT or EDT may be recommended for the first-line treatment of H. pylori infection.
