Intravenous metronidazole-, levofloxacin-containing triple therapy for treating patients with Helicobacter pylori-related active peptic ulcer complications: A pilot study
Abstract
Objective: The aim of this pilot study was to evaluate the efficacy and safety of intravenous use esomeprazole, metronidazole, and/or levofloxacin in the treatment of Helicobacter pylori (H. pylori)-associated peptic ulcer complications.
Methods: Inpatients with peptic ulcer complications who were not able to take oral medicine were randomly assigned to three groups: triple therapy (esomeprazole, levofloxacin, metronidazole) and dual therapy (esomeprazole, levofloxacin/metronidazole) for 7 days. After intravenous treatment, all patients received open-label oral esomeprazole 20 mg bid for another 1 month. All subjects were followed up for gastroscopy at the seventh day of intravenous treatment to confirm the ulcer healing and 13 C-urea breath test to confirm successful H. pylori eradication 4-6 weeks after completion of oral esomeprazole therapy.
Results: The H. pylori eradication rate of both LEV-dual therapy (33.3%, 95% CI: 9.7%-70.0%) and MTZ-dual therapy (50%, 95% CI: 21.5%-78.5%) was significantly lower than that of triple therapy (95%, 95% CI: 71.1%-97.4%) (p = .003, .016). There were no significant differences in the adverse effects among all treatment groups, and the adverse effects were rare.
Conclusions: The intravenous triple regimen, consisting of proton-pump inhibitor, metronidazole, and levofloxacin, could be considered in patients of H. pylori-associated peptic ulcer complications if oral medicine cannot be provided.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
