Helicobacter pylori,eradication therapy
Brief summary
Ａretrospective study was conducted to compare the efficacy, safety, and cost-effectiveness of traditional proton pump inhibitors (PPI ) and Potassium-competitive acid blockers ( P-CAB )for clarithromycin-based bismuth-containing quadruple therapy in the management of Helicobacter pylori eradication.
Detailed description
This study retrospectively enrolled participants with H. pylori infection who received bismuth quadruple regimen containing clarithromycin. The basic information, treatment results, adverse reactions and compliance of the patients were collected. According to the type of acid inhibitors, participants were divided into traditional PPI group and P-CAB group. Traditional PPI group which were divided into lansoprazole group and esomeprazole group. The eradication rate, safety, compliance of H. pylori in different treatment regimens was evaluated. Multivariate analysis was performed to identify predictors of eradication failure.
Interventions
OTHERPPI regimen
All patients received PPI regimen( lansoprazole or esomeprazole,bismuth amoxicillin,clarithromycin for14 days). Demographic data,treatment regimens, outcomes of therapy, adherence to therapy and adverse event were retrieved.
OTHERP-CAB regimen
All patients received P-CAB regimen(vonoprazan,bismuth ,amoxicillin,clarithromycin for14 days). Demographic data,treatment regimens, outcomes of therapy, adherence to therapy and adverse event were retrieved.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Rate of eradication success | 1 month | Six weeks after completion of treatment, numbers of patients get H.pylori eradicated supported by negative 13C-UBT results will be investigated by an independent researcher. Then eradication rate in each group will be calculated by using intention-to-treat (ITT) analysis, modified intention to treat analysis (MITT) and per-protocol (PP) analysis. The ITT analysis includes all the patients who take at least one dose of the study medications. The MITT analysis is limited to patients who complete follow-up.The PP analysis is limited to patients who take over 90% of the study medications and complete follow-up. |
| Prevalence of adverse events | 1 month | At the follow-up, adverse events complained by patients will be recorded by an independent researcher, meanwhile CTCAE v5.0 was used to evaluate severity of adverse events.The prevalence of adverse events was compared between the two group |
| Number of participants with good compliance | 1 month | Compliance was evaluated by assessing the total pills patients have taken.Compliance was defined as good whenmore than 90% or less than 120% of the total pills were taken |
