摘要: 目的 探讨抗黏液蛋白A(MxA)启动子-88位点的单核苷酸多态性(SNP)与干扰素(IFN)疗效的关系.方法 262例慢性乙型肝炎(CHB)患者给予α-IFN治疗12个月.应用多聚酶链式反应(PCR)及限制片段长度多态性(RFLP)分析宿主的抗病毒蛋白MxA启动子-88位点的SNP,并比较SNP与IFN疗效的关系.结果 262例患者中,IFN持久应答(SR)50例(19.1%),非持久应答(NSR)212例(80.9%).MxA启动子-88位点GT基因型频率在SR组为50.0%,与NSR组的17.5%比较,差异有统计学意义(P<0.01).结论 MxA启动子88位点为GT杂合基因型的CHB患者对IFN治疗反应好.

Abstract: Objective To identify the host single nucleotide polymorphisms(SNP) of the MxA promoter 88 site and predict interferon response in hepatitis B patients.Methods 262 chronic hepatitis B patients were treated with α-IFN for 1 year.Single nucleotide polymorphisms of the MxA promoter-88 site were examined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) and were compared with the responsiveness of hepatitis B patients to IFN.Results 212 cases were no sustained response(NSR);50 with sustained response(SR).The SNP of MxA promoter-88 was found having a significant difference in the genotypic frequency distribution between SR and NSR patients.The rate of GT heterozygote was 50.0% in SR and 17.5% in NSR,P<0.01.Conclusion Patients with GT genotype at MxA promoter-88 responds well to IFN treatment.

Key words: chronic hepatitis B, MxA, interferon, single nucleotide polymorphisms(SNP)
