Аннотация
BACKGROUND: Helicobacter pylori (H. pylori) is a Gram-negative bacterium that relies on flagellar motility to colonize the stomach, damaging the gastric mucosa through various mechanisms and leading to various digestive disorders. Accurate assessment and precise treatment are essential in initial intensive therapy.
AIM: To investigate the efficacy and safety of a vonoprazan (VPZ)-based triple regimen for first-line eradication of H. pylori in China.
METHODS: This multicenter noninferior randomized controlled trial (June 2022 to November 2023) involved 524 H. pylori-positive patients across 19 centers in Shandong, China. Participants were randomized to 14-day esomeprazole/bismuth/amoxicillin/clarithromycin (EBAC), 14-day VPZ/amoxicillin/clarithromycin (VACa), or 10-day VPZ/amoxicillin/clarithromycin (VACb) - all administered twice daily. Primary outcomes (eradication rates) were assessed via intention-to-treat (ITT) and per-protocol (PP) analyses. Secondary endpoints included adverse events and adherence. Noninferiority testing and χ 2 tests were used for statistical comparisons.
RESULTS: A total of 524 patients participated in this study. In ITT analysis, the eradication rates of the EBAC, VACa, and VACb groups were 72.6% (127/175), 88.0% (154/175), and 83.3% (145/174), respectively (P = 0.001). The difference in the eradication rate between the EBAC and VPCa groups was 15.4% [95% confidence interval (CI): 7.3-23.6, P < 0.001], and that between the EBAC and VACb groups was 10.8% (95%CI: 2.1-19.4, P = 0.018). In PP analysis, the eradication rates of the EBAC, VACa, and VACb groups were 81.4% (127/156), 93.9% (154/164), and 90.6% (145/160), respectively (P = 0.001). There was no significant difference in the incidence of adverse reactions among the three groups, which were 36.6%, 33.8% and 29.6%, respectively (P = 0.50).
CONCLUSION: VPZ-based triple therapies demonstrate noninferiority to 14-day bismuth-containing regimens, with the 10-day regimen showing comparable efficacy and similar adverse event rates.
