Overview

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.

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.

Outcomes

Primary Outcomes

Eradication rate at different time intervals

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.

Time frame: immediately after the procedure

Secondary Outcomes

Type、Rate and severtiry of adverse reactions

Time frame: Immediately after the procedure

Patient compliance

Good compliance is defined as the actual dosage is within the range of 80%-100% of the dosage that should be taken.

Time frame: Immediately after the procedure
