The study of CD55,CD59,CD34 on the early diagnosis of AA-PNH / 中国免疫学杂志

ABSTRACT

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.
