[Polymorphism of cytochrome P-450 gene in the light of Helicobacter pylori eradication efficiency].

Recent studies of cytochrome P-450 gene polymorphism showed that it may influence the outcome of treatment of Helicobacter pylori (Hp) infection. The literature data concerning effects of genetic factors on the results of eradication therapy of peptic ulcer in the Russian population are scarce and the problem needs further investigation. The aim of this work was to examine CYP2C19 polymorphism in a mixed population of the city and region of Moscow and evaluate its effect on the efficiency of eradication therapy of Hp infection. The prospective study of a cohort of 82 patients with Hp-induced gastric and duodenal ulcers examined in conformity with the current health care standards. All the patients received first line eradication therapy during 7 days. Its efficiency was found to be dependent on CYP2C19 polymorphism among other factors.
