Abstract：Objective: To explore the association of chemokine family CXC gene polymorphism with response to therapy in chronic hepatitis C virus patients, so as to timely intervene and improve the curative effect in the course of treatment. Methods: A total of 282 patients with chronic hepatitis C were enrolled in this study. The patients were treated for 48 weeks and were followed up for 24 weeks with the treatment of polyethylene glycol interferon α combined with ribavirin.The results of sustained virological response(SVR) were observed. All patients were genotyped by TaqManMGB fluorescence probe PCR. Logistic regression analysis was used to analyze the influencing factors of SVR. Results: After 48 weeks of followup,180(63.83%) HCV patients achieved SVR. Multivariate Logistic regression analysis showed that the high level of thyrotropin(OR=1.22,95% CI=1.04-1.42) and the low level of blood glucose(OR=0.85,95%CI=0.72-0.99) were conducive to increasing the SVR rate. The high level of baseline HCVRNA(OR=0.72,95% CI=0.56-0.99) was not conducive to increasing SVR. However, CXCL9 rs10336(OR=0.97,95%CI=0.40-2.33),rs3733236 (OR=0.89,95%CI=0.43-1.87)and CXCL12 rs1801157(OR=1.31,95%CI=0.80-1.86)were not significantly associated with SVR. Conclusion: Baseline HCVRNA, serum thyrotropin and blood glucose were the independent influencing factors of SVR in patients with chronic hepatitis C.There was no significant association of antiviral therapy with chemokine gene polymorphism in hepatitis C patients.
