Efficacies of Two Bismuth Quadruple Therapies in the Second-line Treatment of H Pylori Infection


Brief description of study

From the profiles of antibiotic susceptibility data following eradication therapy, tetracycline, amoxicillin and levofloxacin are all good candidates of antibiotics used in the rescue treatment.

Detailed Study Description

The H pylori-infected adult patients with failure of standard triple therapy and H pylori-infected adult patients with failure of non-bismuth quadruple therapy are randomly assigned to either TL quadruple therapy (esomeprazole-bismuth-tetracycline-levofloxacin regimen) or AL quadruple therapy (esomeprazole-bismuth-amoxicillin-levofloxacin regimen) for 10 days. Repeated endoscopy with rapid urease test, histological examination and culture or urea breath tests is performed at six weeks after the end of anti-H pylori therapy.
