RESUMEN
Objective To study the changes of the humoral immune parameters in patients after infusion of irradiated platelets and the correlation with platelet transfusion refractoriness(PTR).Methods 126 patients with malignant blood diseases of transfusion in our hospital by more than twice were randomly divided into observation group and control group by randomized single-blind allocation method.The observation group was treated with transfusion note γ irradiated platelets,and the control group was treated with infusion ordinary way of apheresis platelets.Before and after transfusion,the changes of vivo complement(C3,CA),immune globulin (IgG,IgM,IgA),C-reactive protein (CRP) and circulating immune complexes(CIC) were detected andplatelet transfusion efficiency and the correlation between changes of immune parameters and the occurrence of invalid infusion.Results The infusion of platelets in patients of C3,C4,IgG,IgM and CIC of the control group were significantly higher than the observation group(all P ＜0.05).There was no significant changes in IgA of the two groups,but the CRP had the high trends.The infusion efficiency of the observation group was 87.3％,which was significantly higher than that of the control group(61.9％)(χ2 =8.92,P ＜ 0.05),blood transfusion after the PTR immune parameters in patients with C3,C4,IgG,IgM,CRP,CIC significantly higher than before,the difference was statistically significant(all P ＜0.05).Conclusion The bodyimmune parameters with PTR is closely related to humoral immune parameters,and the infusion of γirradiated platelets alleviate to some extent,further improve clinical infusion effective rate.
