摘要
目的:探讨CD55、CD59、CD34抗原在再障阵发性血红蛋白尿综合征(AAPNH)的早期诊断中的价值,寻找AAPNH早期诊断敏感指标,进而达到早期发现、早期诊断、早期治疗的目的。方法:应用流式细胞仪测定AAPNH综合征患者的CD55、CD59、CD34抗原变化关系,并与PNH、AA等疾病组以及正常对照组CD55、CD59、CD34抗原相互变化关系,经过统计学处理,找出相关性。结果:结果表明AAPNH、PNHCD55、CD59、CD34抗原较AA及其他疾病组及正常对照组明显减低,并与溶血试验中溶血程度呈正相关,且早于其他溶血指标。结论:CD55、CD59、CD34抗原表达率可作为PNH、AAPNH综合征早期诊断最敏感指标,并与预后转归密切相关。
Objective:To study the significance of CD55,CD59 and CD34 in the early diagnosis of aplastic anemia-paroxysmal nocturnal hemoglobi nuria(AA-PNH),and to search for a sensitive marker of the early diagnosis,so as to achieve the objective of early finding,early diagnosis and early treatment.Methods:CD55,CD59 and CD34 in AA-PNH patients were detected by Flow cytometry,the relationship among CD55,CD59 and CD34 in AA-PNH patients,PNH,AA patients and control group were studied to find out their statistic relevance.Results:The levels of CD55,CD59 and CD34 of PNH and AA-PNH were significantly lower than AA group and any other group and control group,the markers were positively correlated with hemolysis degree and were earlier than other markers of hemolysis.Conclusion:CD55,CD59 and CD34 antigens may act as the most sensitive marker of early diagnosis in PNH and AA-PNH syndrome,and have a close correlation with prognosis.
