摘 要:目的:联合分析氯吡格雷药物代谢相关基因CYP2C19、ABCB1、PON1单核苷酸多态性位点与经皮冠状动脉介入治疗术后患者氯吡格雷抵抗发生及其血小板聚集抑制率之间的关系。方法回顾性研究2015年4至12月入住上海交通大学医学院附属仁济医院心内科且进行介入治疗的299例患者。采用血栓弹力图测定患者( ADP )诱导的血小板聚集抑制率,采用数字荧光杂交测定CYP2C19(rs4244285与rs4986893)、ABCB1(rs1045642)、PON1(rs662)位点的基因型。根据患者血小板聚集抑制率的大小分为氯吡格雷抵抗(CR)组(17例)和非氯吡格雷抵抗(NCR)组(282例)及氯吡格雷低反应(CLR)组(54例)和非氯吡格雷低反应(CLR)组(245例)。根据CYP2C19(rs4244285与rs4986893)分为快代谢型(EM)、中间代谢型(IM)、慢代谢型(PM)。 CR组的年龄(71.1±11.1)岁高于NCR组(65.02±10.51)岁,且差异有统计学意义(t=2.559,P<0.05)。结果 CYP2C19的PM组与EM+IM组相比血小板聚集抑制率下降且有统计学意义(Z=-2.065,P=0.039)且此差异并不由年龄引起(Z=0.405,P>0.05)。 PON1(rs662)位点的基因多态性与CR(χ^2=0.175,P=0.916)、CLR (χ2=1.589,P=0.452)的发生及血小板聚集抑制率水平不具有相关性( Z=-0.030,P=0.976)。ABCB1(rs1045642)与CR(χ^2=1.722,P=0.423)、CLR(χ^2=0.176,P=0.916)的发生及血小板聚集抑制率水平不具有相关性(Z=-0.331,P=0.741)。结论 CYP2C19弱代谢型与氯吡格雷诱导的血小板聚集抑制率下降具有相关性;ABCB1(rs1045642)、PON1(rs662)位点的基因多态性与氯吡格雷抵抗不具有相关性。同时,在CYP2C19弱代谢型患者上也不会加重其血小板聚集抑制率的降低。Objects To investigate the correlation of the single nucleotide polymorphism ( SNP) of clopidogrel related gene CYP2C19, ABCB1, PON1 to the occurrence of clopidogrel resistance ( CR) and TEG among patients after percutaneous coronary intervention.Methods A total of 299 patients after PCI were enrolled from April 2015 to December 2015.It genotyped the CYP2C19(rs4244285,rs4986893)ABCB1 ( rs1045642 ) and PON1 ( rs662 ) gene, measured clopidogrel response by TEG.Accordingly, all the enrolled 299 patients were then divided into CR group (n=17) +non-CR (NCR) group (n=282) or CLR group (n=54) +non-CR (NCR) group (n=245) by TEG(%).All the patients were divided into EM、IM and PM group by CYP2C19 genotype.The age of patient in CR (71.1 ±11.1) years old is higher than NCR (65.02 ±10.51) years old (t=2.559, P〈0.05).Results CYP2C19 PM was associated with decreased of TEG(ADP) (Z=-2.065, P=0.039), while it was not related to the age of patient(Z=0.405,P〉0.05).There was no significant difference between CR(χ^2 =0.175,P=0.916) CLR(χ^2 =1.589,P=0.452)and the level of TEG(ADP) (Z=-0.030,P=0.976) in PON1(rs662) polymorphism.There was no significant difference between CR(χ^2 =1.722,P=0.423) CLR(χ^2 =0.176,P=0.916) and the level of TEG(ADP) (Z=-0.331,P=0.741) in ABCB1(rs1045642) polymorphism.Conclusions CYP2C19 PM is associated with decreased of TEG(ADP).It is considered that no correlation exists between ABCB1(rs1045642) and PON1(rs662) polymorphism and clopidogrel resistance in patients with coronary heart diseases.The loss of function of ABCB1 ( rs1045642 ) and PON1 ( rs662 ) is not associated with decreased of TEG(ADP) in CYP2C19 PM patients.
