Antibiotic Combination for H. Pylori Eradication in Penicillin-allergic Patients

Registration Number
NCT05023577
Lead Sponsor
Shanghai Zhongshan Hospital
Brief Summary

This randomized controlled clinical trial will compare the eradication efficacy of bismuth quadruple therapy containing clarithromycin+metronidazole, clarithromycin+levofloxacin, or metronidazole+levofloxacin for Helicobacter pylori first-line treatment in penicillin-allergic patients. The completion of this trial will expand new therapy for the treatment of Helicobacter pylori, which can not only ensure clinical efficacy, but also reduce the use of antibiotics.

Primary Outcome Measures
NameTimeMethod
Eradication rate of Helicobacter pyloriAt least 4 weeks after completion of therapy

Eradication of Helicobacter pylori was defined as negative result of urea breath test (\<4‰ cut-off value).

Secondary Outcome Measures
NameTimeMethod
Eradication rate of Helicobacter pylori susceptible strainsAt least 4 weeks after completion of therapy

Eradication of Helicobacter pylori was defined as negative result of urea breath test (\<4‰ cut-off value). The antibiotic susceptible strains were assessed using the E test method.

Eradication rate of Helicobacter pylori resistant strainsAt least 4 weeks after completion of therapy

Eradication of Helicobacter pylori was defined as negative result of urea breath test (\<4‰ cut-off value). The antibiotic resistant strains were assessed using the E test method.
