摘要: 目的 分析乌鲁木齐地区哈萨克族献血人群血小板特异性抗原HPA-15基因多态性,为临床血小板输注提供依据。方法 采用聚合酶链-序列特异性引物技术(PCR-SSP)对乌鲁木齐地区100名无血缘关系的哈萨克族献血者的HPA-15系统进行基因分型,计算基因型频率和基因频率。结果 哈萨克族献血人群HPA-15a/15a、HPA-15a/15b、HPA-15b/15b基因型频率分别为0.21、0.53、0.26。HPA-15a、HPA-15b的基因频率分别为0.475和0.525。HPA-15a、HPA-15b抗原不配合率分别为0.1997和0.1747。结论 乌鲁木齐地区哈萨克族HPA-15抗原不配合概率高,可能导致产生同种免疫性血小板抗体的概率增加,在临床血小板输注中的作用值得重视。

Abstract: Objective To investigate the genetic polymorphism of HPA-15 alleles in Kazak blood donors from Urumqi area and to provide valuable data for clinical platelet transfusion. Method sHPA-15 system genotype was determined by PCR-SSP method in 100 Kazak blood donors from Urumqi. The frequencies of gene and genotype were calculated and compared with that in other areas. Results The frequencies of HPA-15aa,HPA-15ab and HPA-15bb in Kazak blood donors were 0.21,0.53 and 0.26,respectively. The gene frequency of HPA-15a and HPA-15b were 0.475 and 0.525,respectively. The frequencies of antigen incompatibility of HPA-15a and HPA-15b were 0.1997 and 0.1747,respectively. Conclusion The frequency of antigen incompatibility of HPA-15 is higher,which indicate HPA-15 may increase the probability of human platelet alloimmunization and may play an important role in clinical platelet transfusion.
