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.

Conditions

Helicobacter Pylori Infection

Outcome Measures

Primary Outcomes (1)

• 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.
