A randomized, multicenter and noninferiority study of amoxicillin plus berberine vs tetracycline plus furazolidone in quadruple therapy for Helicobacter pylori rescue treatment.

ABSTRACT: OBJECTIVE:Helicobacter pylori (H. pylori) infection is closely associated with gastric ulcers and gastric adenocarcinomas. We aimed to assess the efficacy and safety of a quadruple regimen with amoxicillin plus berberine vs tetracycline plus furazolidone in rescue therapy for H. pylori eradication. METHODS:We conducted a randomized, open-label, multicenter, noninferiority trial. Patients with previous treatment failures recruited from five centers were randomized (1:1) to receive a regimen with esomeprazole and bismuth plus either berberine and amoxicillin (the BA group) or tetracycline and furazolidone (the TF group) for 14?days. Their H. pylori infection status was confirmed 4-8?weeks after treatment. The primary outcome was the eradication rate. The secondary outcomes included the rates of symptom improvement, compliance, and adverse events. This study was registered at ClinicalTrials.gov (NCT03609892). RESULTS:Altogether 658 participants were consecutively enrolled. An intention-to-treat analysis demonstrated that the two regimens achieved a similar eradication rate (76.3% vs 77.5%; P = 0.781). The per-protocol analysis reached a similar result (81.5% vs 85.0%; P = 0.278). The eradication rate reached in the BA group was greater than the pre-established margin of noninferiority, at -10% (the lower bounds of the 95% CI were?-7.66% and?-9.43%, respectively). The rate of adverse events was lower for the BA group than the TF group (18.5% vs 26.1%, P = 0.024). Rates of compliance and symptom improvement were similar for the two therapies. CONCLUSION:The efficacy of both regimens in rescue treatment for H. pylori eradication was satisfactory, 14-day BA-based quadruple therapy is noninferior to the TF-based therapy.

Project description:BackgroundHigh-dose dual therapy (HDDT) with proton pump inhibitors (PPIs) and amoxicillin has attracted widespread attention due to its favorable efficacy in eradicating Helicobacter pylori (H. pylori). This study aimed to compare the efficacy and safety of high-dose PPI-amoxicillin dual therapy and bismuth-containing quadruple therapy for H. pylori rescue treatment.MethodsThis was a prospective, randomized, multicenter, non-inferiority trial. Patients recruited from eight centers who had failed previous treatment were randomly (1:1) allocated to two eradication groups: HDDT (esomeprazole 40 mg and amoxicillin 1000 mg three times daily; the HDDT group) and bismuth-containing quadruple therapy (esomeprazole 40 mg, bismuth potassium citrate 220 mg, and furazolidone 100 mg twice daily, combined with tetracycline 500 mg three times daily; the tetracycline, furazolidone, esomeprazole, and bismuth [TFEB] group) for 14 days. The primary endpoint was the H. pylori eradication rate. The secondary endpoints were adverse effects, symptom improvement rates, and patient compliance.ResultsA total of 658 patients who met the criteria were enrolled in this study. The HDDT group achieved eradication rates of 75.4% (248/329), 81.0% (248/306), and 81.3% (248/305) asdetermined by the intention-to-treat (ITT), modified intention-to-treat (MITT), and per-protocol (PP) analyses, respectively. The eradication rates were similar to those in the TFEB group: 78.1% (257/329), 84.2% (257/305), and 85.1% (257/302). The lower 95% confidence interval boundary (-9.19% in the ITT analysis, - 9.21% in the MITT analysis, and -9.73% in the PP analysis) was greater than the predefined non-inferiority margin of -10%, establishing a non-inferiority of the HDDT group vs. the TFEB group. The incidence of adverse events in the HDDT group was significantly lower than that in the TFEB group (11.1% vs. 26.8%, P < 0.001). Symptom improvement rates and patients' compliance were similar between the two groups.ConclusionsFourteen-day HDDT is non-inferior to bismuth-containing quadruple therapy, with fewer adverse effects and good treatment compliance, suggesting HDDT as an alternative for H. pylori rescue treatment in the local region.Trial registrationClinicaltrials.gov, NCT04678492.
