摘要 目的:系统分析山西地区血液病患者人类血小板抗原(HPA)基因分型及其多态性,为HPA基因库建设提供实验数据和理论依据,为本地区血小板输注无效(PTR)患者的血小板(PLT)有效输注建立理论和临床基础。方法:选取血液病住院患者97例,分为输注有效组(52例)和输注无效组(45例),提取全血DNA,采用聚合酶链反应-序列特异性引物技术(PCR-SSP)进行HPA-1~6,15抗原系统基因分型。结果:输注有效组HPA-1,4,5,6主要以aa型为主,HPA-3和HPA-15杂合度较高。输注无效组HPA-1,4,5,6主要以aa型为主,HPA-2,HPA-3,HPA-15杂合度较高。结论:山西地区人类血小板同种抗原血型系统基因多态性表现出人群特点。人类血小板抗原血型中a基因频率明显较高;血液病患者HPA-2,HPA-3,HPA-15抗原对配偶不配合比例高。提示临床治疗中对于反复输注PLT的血液病患者需高度关注HPA-2,HPA-3,HPA-15基因型,并对其进行检测,尽量同型输注,避免产生血小板同种抗体,引起血小板输注无效。
