Effect of<i>MDR1</i>C3435T polymorphism on cure rates of<i>Helicobacter pylori</i>infection by triple therapy with lansoprazole, amoxicillin and clarithromycin in relation to<i>CYP </i>2C19 genotypes and 23S rRNA genotypes of<i>H. pylori</i>

Abstract

Polymorphism of MDR1 is one of the determinants of successful eradication of H. pylori by the triple therapy with lansoprazole, amoxicillin and clarithromycin, together with CYP2C19 genotype and bacterial susceptibility to clarithromycin.
