Vonoprazan is noninferior to proton pump inhibitors in bismuth-containing quadruple therapy for the treatment of Helicobacter pylori infection: A propensity score matching analysis
Abstract
Objective: This study aimed to evaluate the efficacy and safety of vonoprazan (VPZ) versus proton pump inhibitor (PPI) in clarithromycin-based bismuth-containing quadruple therapy (C-BQT) for the treatment of Helicobacter pylori (H. pylori) eradication.
Methods: Medical records of patients in whom H. pylori was eradicated between 1 July 2018 and 31 December 2021 were retrieved retrospectively from the Outpatient Unit of Qilu Hospital. Efficacy, safety, and compliance were compared between VPZ-based and PPI-based C-BQT, containing vonoprazan 20 mg or proton pump inhibitors (lansoprazole 30 mg or esomeprazole 20 mg), bismuth 220 or 200 mg, amoxicillin 1000 mg, and clarithromycin 500 mg, twice daily for 2 weeks by 1:1 propensity score matching analysis. The trial was registed on ClinicalTrials.gov (registration no. NCT05301725).
Results: The H. pylori eradication rates of VPZ-based and PPI-based therapies were 88.8% (151/170) and 87.6% (149/170) in the intention-to-treat analysis, 94.1% (144/153) and 91.1% (144/158) in the per-protocol analysis, respectively. The noninferiority of VPZ to PPI was confirmed in all analyses (P < 0.001). The incidence of adverse events was 30.0% (51/170) and 27.1% (46/170) in the VPZ-based and PPI-based groups, respectively. VPZ-based and PPI-based therapies were well tolerated and showed good patient compliance without significant differences.
Conclusions: VPZ-based therapy resulted in a satisfactory eradication rate and was well tolerated for H.…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
