Tailored Therapy for Helicobacter Pylori Treatment in Patients With Penicillin Allergy

Antibiotic Susceptibility-based Tailored Therapy for Helicobacter Pylori Treatment in Patients With Penicillin Allergy: a Prospective Clinical Trial

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.
