- Registration Number
- NCT03708848
- Lead Sponsor
- Shanghai Jiao Tong University School of Medicine
- Brief Summary
Increasing drug resistance presents a significant challenge to the efficacies of common empiric eradication regimens for Helicobacter pylori treatment in the mainland of China. Tailored therapy may be the best choice to achieve good efficacy, especially in patients with penicillin allergy. Few studies had evaluated the patients with penicillin allergy.This study is designed to evaluate the efficacy and safety of antibiotic sensitivity-based tailored therapy for Helicobacter pylori treatment in the patients with penicillin allergy.

- Primary Outcome Measures
Name Time Method Helicobacter pylori eradication rate Six weeks after completion of therapy Six weeks after completion of therapy, H. pylori eradication was assessed by ¹³C-urea breath test. Eradication was defined as negative result from urea breath test (\<4‰) (4‰ as the cutoff value).
- Secondary Outcome Measures
Name Time Method Rate of adverse effects Within 7 days after completion of therapy The subjects were asked to grade the severity of adverse events according to their influence on daily activities, experienced as "mild" (transient and well tolerated), "moderate" (causing discomfort and partially interfering with daily activities), or "severe" (causing considerable interference with daily activities)
Compliance rate Within 7 days after completion of therapy Compliance was defined as poor when they had taken less than 80% of the total medication.
