BACKGROUND: The aim of this study was to evaluate the efficacy, tolerability and safety of modified bismuth-based quadruple therapy for the second-line eradication treatment of Helicobacter pylori (H. pylori) infection.
METHODS: Out of 758 patients treated between January 2010 and December 2015, 155 patients (20.45%) remained H. pylori positive after the first line treatment and received the second-line treatment consisting of colloidal bismuth subcitrate (240 mg twice daily), pantoprazole (40 mg twice daily), metronidazole (500 mg twice daily) and moxifloxacin (400 mg once daily) for 14 days. Six weeks after the completion of treatment patients were retested for the presence of H. pylori infection with 13C urea breath test.
RESULTS: Out of 155 patients, 142 patients completed their second-line regimens. 13 patients were excluded from the study: 4 experienced adverse effects that have led to discontinuation of treatment, 5 were lost to follow-up and 4 complied poorly with medication. The eradication rates were 80.64% (125/155) and 88.02% (125/142) according to intention-to-treat and per-protocol analyses. Compliance with the therapy was 89%.
CONCLUSIONS: Moxifloxacin in modified bismuth-based quadruple therapy was found to be effective and safe with good drug compliance; therefore it may be an acceptable alternative to other second-line eradication protocols.
