Levofloxacin-Based Triple Therapy versus Bismuth-Based Quadruple Therapy for Persistent Helicobacter pylori Infection: A Meta-Analysis. CME
Abstract
BACKGROUND: Levofloxacin-based triple therapy has been suggested as an alternative salvage therapy to bismuth-based quadruple therapy for persistent Helicobacter pylori (H. pylori) infection. METHODS: A search of PUBMED, EMBASE, EBM Review databases and abstracts from recent Digestive Disease Week, United European Gastroenterology Week, and European Helicobacter Study Group conferences was performed. Randomized controlled trials (RCTs) comparing levofloxacin-based triple salvage therapy (levofloxacin + amoxicillin + PPI) to bismuth-based quadruple salvage therapy (bismuth + tetracycline + metronidazole + PPI) were selected for meta-analysis. Additionally, all prospective trials evaluating this levofloxacin-based triple therapy as salvage therapy were pooled to analyze optimal levofloxacin treatment duration and dosing. All selected trials confirmed prior treatment failure and post-salvage treatment eradication. RESULTS: Four RCTs compared a 10-day regimen of levofloxacin-based triple therapy to 7-day bismuth-based quadruple therapy (n = 391 patients). Levofloxacin-based triple therapy was superior to quadruple therapy (RR = 1.41 [95% CI: 1.25-1.59]). Levofloxacin-based triple therapy was better tolerated than quadruple therapy with a lower incidence of side effects (RR = 0.51 [95% CI: 0.34-0.75]) and side effects prompting discontinuation of therapy (RR = 0.30 [95% CI: 0.10-0.89]). Eleven trials (n = 547 patients) evaluating levofloxacin-based triple therapy demonstrated…
