过敏性紫癜患儿血管内皮细胞损伤及凝血功能变化的临床意义

Objective To investigate the changes and the role of plasma thrombomodulin(TM),von willebrand factor (vWF) ,and coagulation status indicators in children with Henoch-Schonlein purpura(HSP).Methods The plasma concentrations of TM,vWF were measured by ELISA method and the levels of D-dimer,PT,APTT,palatelet count were measured in 56 acute SHP patients,50 recovery patients and 40 healthy controls. Results The plasma levels of TM、vWF、D-dimer、palatelet count in acute group were significantly higher than those in healthy controls group and those of recovery group ( P = 0. 000). The plasma levels of PT、APTT showed no significant difference among three groups( P ＞ 0. 05 ). The plasma levels of TM、vWF in recovery group were significantly higher than those in healthy controls group ( P ＜ 0. 05, P ＜ 0. 01 ), while the levels of D-dimer、palatelet count reduced to nomal levels(P ＞0. 05). As compared to non-renal damage group, The plasma levels of TM、vWF、 D-dimer were higher in renal damage group ( P ＜ 0. 05, P ＜ 0. 01 ), the levels of PT 、APTT、palatelet count showed no significant difference ( P ＞ 0. 05 ). Conclusion The damage of vascular endothelium and hypercoagulability play an important role in the pathogenesis of HSP. Changes of plasma TM、 vWF、palatelet count can be used as an indicator of the early lesion of renal function.
