- Helicobacter Pylori Infection
- Interventions
- Registration Number
- NCT05620589
- Lead Sponsor
- Shandong University
- Brief Summary
The researchers collect patients who accepted eradication program of the helicobacter pylori but failed to eradicate helicobacter pylor from the outpatient clinic. After rescue therapy, evaluating the effect of retreatment interval on eradication effect of Helicobacter pylori infection.
- Detailed Description
The researchers collect patients who accepted eradication program of the helicobacter pylori but failed to eradicate helicobacter pylor from the outpatient clinic. Record the interval between the last eradication therapy and this time，6-8 weeks after treatment, the subjects will re-take the 13C-urea breath test. Calculating the eradication rates, adverse reaction rates, patient compliance of each group. Evaluating the effect of retreatment interval on eradication effect of Helicobacter pylori infection.

- Primary Outcome Measures
Name Time Method Eradication rate at different time intervals immediately after the procedure 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 two 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.
- Secondary Outcome Measures
Name Time Method Type、Rate and severtiry of adverse reactions Immediately after the procedure Type、Rate and severtiry of adverse reactions
Patient compliance Immediately after the procedure Good compliance is defined as the actual dosage is within the range of 80%-100% of the dosage that should be taken.
