原发性血小板减少性紫癜(ITP)是一种自身免疫性疾病。现已证明血小板表面相关IgG(PAIgG)值,在ITP患者中及某些继发性免疫性血小板减少症患者均明显增高。它可作为ITP诊断、疗效观察和预后估计的指标。我们采用悬液相放免法测定了64例血小板减少症患者及30例正常人的PAIgG值。现报告如下。
Primary thrombocytopenic purpura (ITP) is an autoimmune disease. Platelet surface-associated IgG (PAIgG) values have now been shown to be significantly elevated in patients with ITP and in some patients with secondary immune thrombocytopenia. It can be used as an indicator of ITP diagnosis, efficacy and prognosis. We measured the PAIgG values of 64 patients with thrombocytopenia and 30 normal controls by suspension phase radioimmunoassay. The report is as follows.
