title: [Interluekin-1 beta genetic polymorphism influences the impact of cytochrome P 2C19 genotype on the cure rate of H. pylori eradication therapy].
abstract: Genetic polymorphism of interleukin(IL)-1 beta is associated with differences in gastric acid suppression in response to H. pylori infection. Thus, the polymorphism might affect H. pylori eradication therapy since antibiotics used in treatment regimens may be acid-sensitive. We examined the impact of IL-1 beta genetic polymorphism on the cure rate of triple therapy for H. pylori in relation to cytochrome P(CYP)2C19 genotype. In the normal acid-secretion IL-1 beta genotype group, the cure rate among CYP2C19 poor metabolizers was significantly higher than among those in the CYP2C19 extensive metabolizer groups. IL-1 beta genetic polymorphism, although not an independent factor in treatment outcome, influences the impact of the CYP2C19 genotype on the cure rate of H. pylori eradication therapy.
