Susceptibility-Guided Therapy for Helicobacter Pylori Infection Treatment

Clinical Efficacy and Health Economic Evaluation of Susceptibility-Guided Therapy for Helicobacter Pylori Infection Treatment：Multicenter Randomized Controlled Study

This multicenter randomized controlled clinical trial was conducted to compare the eradication efficacy and health economic benefits of individualized regimens based on HP drug resistance mutation gene detection (multiple PCR method), individualized regimens based on HP traditional drug sensitivity testing (E-test method) and empirical regimens in the Helicobacter pylori treatment.

This multicenter randomized controlled clinical trial was conducted to compare the eradication efficacy and health economic benefits of individualized regimens based on HP drug resistance mutation gene detection (multiple PCR method), individualized regimens based on HP traditional drug sensitivity testing (E-test method) and empirical regimens in the treatment of Helicobacter pylori in patients with chronic gastritis. This study will compare the efficacy of individualized and empirical drug sensitivity regimens, and conduct cost-effectiveness analysis to provide pharmacoeconomic guidance for clinical decision-making. At the same time, it will provide reference for the reasonable pricing of H.pylori drug sensitivity test and considering the health benefits brought by its inclusion in medical insurance.
