RESUMO

Helicobacter pylori (H. pylori) infection is a major cause of duodenal ulcers, gastric ulcers, and gastric cancer. However, the optimal duration for H. pylori eradication therapy remains controversial. Most studies have mainly focused on triple therapy, and there is insufficient research on bismuth-containing quadruple therapy. The aim of this study was to compare the clinical effect of the 10-day bismuth-containing quadruple treatment regimen with the 14-day regime in eradicating H. pylori. We searched PubMed, Embase, Web of Science, and the Cochrane Library for randomized controlled trials published in English until May 2022 according to the eligibility criteria. Summary risk ratios (RRs) and 95% confidence intervals (CIs) for eradication rates, adverse effects, and compliance were calculated for included studies. Four studies, involving 1173 patients, were eligible for inclusion. The eradication rate was similar in the 10-day treatment group and the 14-day treatment group in the intention-to-treat analysis (RR 0.97, 95% CI 0.93 to 1.01). Meanwhile, the incidence of adverse effects was lower in patients who received 10 days of treatment than in those who received 14 days of treatment and patients' compliance was almost the same between two groups. Compared to the 14-day bismuth-containing quadruple regimens, 10-day regimens had similar efficacy and lower incidence of adverse effects. Therefore, the 10-day regimen is safe and well-tolerated and should be recommended for H. pylori infection.

RESUMO

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. pylori eradication, which are comparable to PPIs in C-BQT as a first-line treatment for H. pylori infection.
