Objective: This study aimed to investigate related factors affecting the eradication rate of (Hp) by modified quadruple therapy.
Methods: Between September 2020 and March 2021, 341 patients who were diagnosed with Hp infection and whose infections were confirmed by gastroscopy, a histological examination, and a C13-UBT without culturing and antimicrobial susceptibility studies received a two-week anti-Hp treatment, a modified quadruple therapy, in our department. The result of C13-UBT was rechecked 4 weeks after the drug withdrawal, and the patients were divided into two groups-a success group and a failure group-according to the final breath result.
