Helicobacter Pylori Eradication With Different Bismuth Quadruple Therapies

This study aims to compare efficacy and safety of bismuth-containing quadruple therapy（with rabeprazole amoxicillin clarithromycin）of different kinds of bismuth（Bismuth potassium citrate, pectin bismuth capsules, pectin bismuth particles）in H. pylori first-line eradication. It is hypothesized that different bismuth containing quadruple therapies have comparable eradication efficacy and safety. Patients with confirmed H. pylori positive status will be randomized to one of the treatments described above. At week 2and 6 follow-up visits, a urea breath test(UBT) will be performed to confirm eradication.
