摘要 目的探讨血清中白介素-6及肿瘤坏死因子(TNF)在特发性血小板减少性紫癜患者血清中数值变化及意义。方法采用双抗体夹心酶联免疫(ELISA)定量测定方法检测37例ITP患儿和20例正常健康儿童血清IL-6、TNF-的水平,同时对其中25例ITP患儿进行血小板相关抗体PAIb(IgG、IgA、IgM)的定性测定研究及临床意义,并对ITP患儿外周血中血小板,血小板抗体,血清IL-6,TNF水平进行相关分析。结果ITP患儿血清IL-6、TNF水平均高于正常对照组(P<0.01),ITP患儿治疗前血清IL-6、TNF水平均显著高于治疗后(P<0.01);ITP患儿重度出血组血清IL-6、TNF水平均明显高于轻度出血组(P<0.05);25例ITP患儿血小板相关抗体全阳性9例,阳性率36%(9/25),ITP患儿血小板相关抗体全阳性组血清IL-6、TNF水平均明显高于非全阳性组(P<0.05);ITP患儿治疗前血清IL-6、TNF水平与血小板数均呈负相关(r=-0.802,P<0.01;r=-0.700,P<0.01),IL-6与TNF水平之间呈正相关(r=0.592,P<0.01)。治疗后的IL-6、TNF水平与正常无明显变化。结论IL-6、TNF参与ITP的发病过程,其水平高低随病情轻重、病程而变化,说明除体液免疫以外,细胞免疫也参与了ITP的发病过程。
