Abstract:
Objective To investigate the correlation between platelet-associated antibody and platelet infusion effects.Methods SEPSA was used to detect the platelet-associated antibody of 79 patients with multiple transfusions of platelet,the platelet count before and after platelet infusion was monitored and the corrected count increment (CCI) in lh and 24h were calculated,for those judged to be ineffective platelet infusion,the platelet cross-matching was first done and then received matching infusion again and the infusion effects were analysed. Results 47 cases were detected with platelet antibody positive in 79 patients,accounting for 59.5％ ,the CCI of lh and 24h after infusion in platelet antibody positive group were significantly lower than the negative group, the difference was statistically significant( t = 2. 462、2. 583, all P ＜ 0. 05 ) ;40 cases in positive group had the invalid with the invalid rate of 85.1％which was significantly higher than the negative group, the difference was statistically significant ( x2 = 34. 46, P ＜0. 05 ) ;the CCI of 1h and 24h after infusion in matching success group were significantly higher than the unsuccessful group, the difference was statistically significant( t = 2. 152、2. 230, all P ＜ 0. 05) ;27 cases in matching success group had the effective infusion with the effective rate of 87. 1％ ,which was significantly higher than the unsuccessful group, the difference was statistically significant ( x2 = 4. 34, P ＜ 0. 05). Conclusion The production of anti-platelet antibody was a major immune factor which lead to platelet transfusion refractoriness ,the blood platelet cooperative infusion could be a good solution for the platelet transfusion refractoriness.
