Triple Versus Quadruple Therapy for the Eradication of Helicobacter Pylori

Shandong University375 enrolled

Overview

The study aimed to compare the efficacy and safety of 7-day and 14-day vonoprazan-amoxicillin-tetracycline triple therapy with 14-day vonoprazan-amoxicillin-tetracycline-bismuth quadruple therapy for the eradication of Helicobacter pylori. Subjects were randomized to receive the intervention and were reviewed by 13C-urea breath test after 6 weeks. The eradication rates, adverse reaction rates and patient adherence were calculated.

H. pylori-positive patients without eradication history were recruited according to inclusion and exclusion criteria and randomized to the intervention: 14-day quadruple regimen: Vonoprazan 20mg bid + Amoxicillin 1000mg bid + Tetracycline 500mg qid + Bismuth 220mg bid for 14 days 14-day triple regimen: Vonoprazan 20mg bid + Amoxicillin 1000mg bid + Tetracycline 500mg qid 14 days 7-day triple regimen: Vonoprazan 20mg bid + Amoxicillin 1000mg bid + Tetracycline 500mg qid 7 days Subjects were asked to record adverse events and 6 weeks after treatment, 13C-urea breath test was tested for confirmation. The eradication rates, adverse reaction rates and patient adherence were calculated and analysed, and the results were analysed to provide more information for eradication regimens of H. pylori.

Outcomes

Primary Outcomes

Eradication rate

13C-urea breath test was used to determine whether eradication was successful. Both intention to treat (ITT) and per-protocol (PP) analyses will be used for the assessment of the eradication rates of Helicobacter pylori infections in the three groups. The ITT analysis includes all randomly assigned patients who take at least one dose of the study medications. The PP analysis is limited to patients who take over 90% of the study medications and complete follow-up.

Time frame: Immediately after follow-up check

Secondary Outcomes

Rate of adverse reactions

A questionnaire on drug-related adverse reactions needs to be completed after treatment.

Time frame: Immediately after follow-up check

Patient compliance

A questionnaire on the number of missed and overdosed doses of medication needs to be completed after treatment. Good compliance was defined as taking 80%-120% of the pills.

Time frame: Immediately after follow-up check
