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
- 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.
- 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.

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.
