Abstract
AIM

To evaluate the impact of cytochrome P450 2C19 (CYP2C19) and interleukin-1β (IL-1β) polymorphisms on the efficacy of Helicobacter pylori (H. pylori) eradication by using rabeprazole-based hybrid therapy.

METHODS

A total of 88 H. pylori-infected patients were recruited to receive 14-d of hybrid therapy from March 2013 to May 2014. Three patients were excluded from analysis because of incomplete compliance. Either a follow-up endoscopy or 13C-urea test was performed to determine the results of H. pylori eradication therapy. The genotypes of CYP2C19 and IL-1β were analyzed to investigate the impact on treatment effect.

RESULTS

The total eradication rate of H. pylori was 92.94% (79/85). According to the CYP2C19 genotypes, the rates of H. pylori eradication were 89.19% in extensive metabolizers (EM) and 95.83% in non-EM. The H. pylori eradication rates regarding the IL-1β genotypes were 92.59% in the normal acid secretion group and 93.10% in the low acid secretion group. After multivariable logistic regression analysis, both the genotypes of CYP2C19 and IL-1β had no significant influences on the eradication rates of H. pylori.

CONCLUSION

The CYP2C19 and IL-1β polymorphisms are not significantly independent factors of H. pylori eradication using rabeprazole-based hybrid therapy.

Core tip: In this study, we investigated the efficacy of hybrid therapy as a first-line treatment for Helicobacter pylori eradication and evaluated the independent predictor associated with eradication efficacy, including cytochrome P450 2C19, interleukin-1β (IL-1β)-511 polymorphism and antibiotic resistance. This study is pilot work investigating the impact of the IL-1β-511 polymorphism on the eradication rate of hybrid therapy.
