Randomized Controlled Trial Multicenter Study
Empirical levofloxacin-containing versus clarithromycin-containing sequential therapy for Helicobacter pylori eradication: a randomised trial.
Antimicrobial drug resistance is a major cause of the failure of Helicobacter pylori eradication and is largely responsible for the decline in eradication rate. Quadruple therapy has been suggested as a first-line regimen in areas with clarithromycin resistance rate >15%. This randomised trial aimed at evaluating the efficacy of a levofloxacin-containing sequential regimen in the eradication of H pylori-infected patients in a geographical area with >15% prevalence of clarithromycin resistance versus a clarithromycin containing sequential therapy. ⋯ In an area with >15% prevalence of clarithromycin resistant H pylori strains, a levofloxacin containing sequential therapy is more effective, equally safe and cost-saving compared to a clarithromycin containing sequential therapy.
