儿童特发性血小板减少性紫癜(ITP)是一种临床常见的因血小板过量破坏而引起的、继发性全身性出血性疾病。以血小板寿限缩短和经常伴有血小板抗体为特征,骨髓象正常或巨核细胞增高。概述与分型本病自1775年Werlhof首先描述以来,关于发病机理等问题、迄今仍未完全解决。但近年已有许多进展、现就此综合介绍于后以供参考。 Children with idiopathic thrombocytopenic purpura (ITP) is a common clinical platelet destruction caused by excessive, secondary systemic bleeding disease. Shortened platelet lifespan and often accompanied by platelet antibodies, bone marrow normal or megakaryocytes increased. Overview and Classification Since the first description by Werlhof in 1775, the pathogenesis and other issues have not yet been fully resolved. However, much progress has been made in recent years and this is a comprehensive introduction for reference later.
