Efficacies of Tetracycline-levofloxacin, Standard Bismuth, Amoxicillin-levofloxacin Quadruple Therapy for H.p

April 28, 2023 updated by: DENG-CHYANG WU, Kaohsiung Medical University

Efficacies of Tetracycline-levofloxacin Quadruple Therapy, Standard Bismuth Quadruple Therapy and Amoxicillin-levofloxacin Quadruple Therapy in the Second-line Treatment of H Pylori Infection

  1. Compare the efficacy of "Tetracycline combined with levofloxacin quadruple therapy", "standard tincture quadruple therapy" and "amoxicillin combined with levofloxacin quadruple therapy" on the second line of Helicobacter pylori sterilization.
  2. To investigate the drug resistance of Helicobacter pylori and the host genotypes of CYP2C19 and IL-1B-511 on the sterilizing effect of three second-line Helicobacter pylori.

Study Overview

Detailed Description

The "standard tincture quadruple therapy" and the "proton pump inhibitor combined with fluoroquinolone and amoxicillin triple therapy" recommended by the 5th Mazdock-Florence Consensus Conference on the second line of Helicobacter pylori treatment The sterilization rate is not ideal (less than 80%). Recently, we have developed a "Tetracycline combined with levofloxacin quadruple therapy" for first-line treatment failure of H. pylori infection, with a relatively high sterilization rate (> 95%). A randomized controlled trial confirmed that the elimination rate of "Tetracycline combined with levofloxacin quadruple therapy" was better than "proton pump inhibitor combined with fluoroquinolone" after "standard triple therapy" and "non-tank tetratherapy" sterilization failure. Triple therapy with amoxicillin.
