Recent advances have demonstrated that thrombotic thrombocytopenic purpura (TTP), characterized by widespread thrombosis in the arterioles and capillaries, is caused by deficiency of a circulating zinc metalloprotease, ADAMTS13. Two types of TTP are recognized: autoimmune TTP, caused by inhibitory antibodies of ADAMTS13, and hereditary TTP, caused by genetic mutations of ADAMTS13. This article reviews the characteristics and function of ADAMTS13, the mechanism by which ADAMTS13 deficiency may lead to thrombosis, and the causes of ADAMTS13 deficiency. It also discusses how the new knowledge may improve the diagnosis and treatment of this previously mysterious disorder.
最近的研究进展表明,血栓性血小板减少性紫癜(TTP)以小动脉和毛细血管广泛血栓形成为特征,是由循环中的锌金属蛋白酶ADAMTS13缺乏所致。TTP分为两种类型:由ADAMTS13抑制性抗体引起的自身免疫性TTP和由ADAMTS13基因突变引起的遗传性TTP。本文综述了ADAMTS13的特征和功能、ADAMTS13缺乏导致血栓形成的机制以及ADAMTS13缺乏的原因。还讨论了这些新知识如何改善对这种以前神秘疾病的诊断和治疗。
