Eradication of Helicobacter pylori is an important treatment strategy in peptic ulcer patients. Current regimens of eradication consist of proton pump inhibitor (PPI) and two antibiotics. The principal enzyme involved in PPIs metabolism is CYP2C19, which exhibits an interindividual variability of activity, mainly due to genetic polymorphism. Two alleles (CYP2C19*2 and CYP2C19*3), responsible for slow PPIs metabolism, were previously associated with higher efficacy of eradication. Recently, a novel CYP2C19 gene variant (CYP2C19*17), associated with faster metabolism of CYP2C19 substrates, was described. In the present study, a potential association between CYP2C19*17 allele and lower H. pylori eradication efficacy was tested in a group of peptic ulcer patients.
