摘要 目的:探讨免疫性血小板减少性紫癜(ITP)患者T细胞免疫状态与发病机制的关系。方法:以25例ITP患者(患者组)和16例健康体检者(对照组)作为研究对象,采用流式细胞术检测T细胞亚群、辅助性T细胞(Th)亚群、活化状态T细胞及调节性T细胞(Treg)的比例。结果:患者组较对照组CD3+CD4+/CD3+和CD4+/CD8(+Th/Tc)比例下降,CD3+CD8+/CD3+的比例升高,差异均有统计学意义(P<0.05或P<0.01)。2组CD8+HLA-DR+/CD3+、CD8+CD25+/CD3+、CD8+HLA-DR+/CD8+及CD8+CD25+/CD8+差异均无统计学意义(P>0.05)。患者组Th1/Th2的比值高于对照组,CD4+CD25+CD127dim/CD4+调节性T细胞(Treg)低于对照组,差异有统计学意义(P<0.05)。结论:ITP患者外周血Th、Tc、Th/Tc亚群紊乱,Th1/Th2向Th1细胞极化,Treg细胞减少参与了该病的免疫发病。
