摘要 目的探讨CD55、CD59检测对阵发性睡眠性血红蛋白尿症(paroxysmal nocturnal hemoglobinuria,PNH)的临床诊断意义。方法采用流式细胞术检测20例PNH患者、45例AA患者和20例正常人外周血粒、红细胞CD55、CD59表达阳性率。结果正常人外周血粒、红细胞CD55、CD59表达阳性率均>95%;部分AA患者外周血粒、红细胞CD55、CD59表达阳性率<95%但均>90%;PNH患者外周血粒、红细胞CD55、CD59表达阳性率与正常对照组和AA组相比均明显减低,差异具有显著性(P<0.01)。结论外周血粒、红细胞CD55、CD59检测是诊断PNH较特异而又敏感的方法 ,特别是对表现不典型的PNH及AA-PNH综合征的诊断具有重要意义。
