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

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.
