To evaluate the coagulation function of children with Henoch-Schönlein purpura (HSP) by thromboelastography (TEG) and conventional coagulation tests (CCTs), and to explore the correlation and consistency of the 2 test methods.A total of 468 children with HSP were selected from January 2017 to December 2017 in Beijing Children's Hospital, Capital Medical University. The TEG and CCTs data were analyzed to evaluate coagulation function of children with HSP, meanwhile, the coagulation results were analysed the superiority of the 2 test methods was compared by Pearson correlation and Kappa consistency analysis.There were no clinically significant abnormalities practically in HSP children by TEG and CCTs analysis, except for D-dimer level was elevated (t=9.15, P<0.001). There were no significant changes for coagulation data from, sex comparison of HSP children (P>0.05 all), but the coagulation reaction time (R), blood clot formation time (K), α-Angle, CI value, fibrinogen, D-dimer and anti-thrombin III in HSP children with different age groups showed difference (P<0.05 all), and the blood in children aged 0-2 years old tended to be hypercoagulable. The TEG indexes demonstrated no significant difference in coagulation function of children with HSP each other (P>0.05). However, CCTs data showed that the blood in children with severe kidney involvement were hypercoagulable. Comparision results of the correlation and consistency of TEG and CCTs in detecting coagulation function of HSP children showed that R was weakly correlated with prothrombin time (PT), International Normalized Ratio (INR) and activated partial thromboplastin time (APTT). There were weak correlation between K, α-Angle and Fib (0.1<|r|<0.4 all). There was no obvious consistency between them each other (kappa<0.4 all).The overall changes in coagulation function in children with HSP are not obvious, but the hyperfibrinolysis in hypercoagulable state may exists. Furthermore, younger age and severe kidney involvement may cause hypercoagulation in HSP children. The weakly correlation and consistency of TEG and CCTs in detecting coagulation function of HSP children are furtherly confirmation, and the 2 test methods may be irreplaceable.血栓弹力图与常规凝血试验对过敏性紫癜患儿凝血功能的评价及对比分析.通过血栓弹力图(thromboelastography,TEG)和常规凝血试验(conventional coagulation test,CCT)评估过敏性紫癜(Henoch-Schönlein purpura,HSP)患儿凝血功能,并探讨2种检测方法的相关性与一致性.选取我院2017年1月- 2017年12月HSP儿童样本468例,分析其TEG和CCT结果,评价患儿凝血状态。同时,通过Pearson相关性和Kappa一致性分析等比较2种检测方法的优劣.HSP儿童TEG与CCT检测指标整体均未见明显临床意义上的异常,仅D-二聚体水平升高(t=9.15,P<0.001)。HSP儿童性别间凝血数据差异无统计学意义,而不同年龄段HSP儿童凝血反应时间(R)、血凝块形成时间(K)、α-Angle、凝血综合指数(CI)、纤维蛋白原(Fib)、D-二聚体和抗凝血酶Ⅲ(AT-Ⅲ)活性均不同(P<0.05),其中0-2周岁患儿血液趋向高凝状态。TEG指标显示,不同肾脏受累程度的HSP患儿凝血功能无明显区别。但CCT数据显示,重度肾脏受累患儿血液偏高凝。TEG与CCT在检测HSP患儿凝血功能的对比结果显示,R与凝血酶原时间(prothrombin time,PT)、国际标准化比值(International Normalized Ratio,INR)及活化部分凝血活酶时间(activated partial thromboplastin time,APTT)均弱相关。K、α-Angle与Fib亦存在弱直线相关性(0.1<|r|<0.4)。其之间未见明显一致性.HSP患儿凝血功能整体变化不明显,但也可能存在高凝状态下的纤溶亢进。同时,低龄、严重肾脏受累可能使HSP患儿血液呈高凝状态。TEG与CCT检测HSP患儿凝血功能相关性和一致性均较弱,2种方法互相不可替代.
