Imbach 等1981年报道用大剂量免疫球蛋白(2g/kg)静脉注射能暂时提高儿童原发性血小板减少性紫癜(1TP)患者的血小板。本文作者报道用同样方法治疗4例成人 ITP 患者取得同样的效果。4例中男女各2例,年龄分别为15、19、70及80岁。有血小板减少伴皮肤及粘膜出血者2例、血小板减少2～3年而无出血症状者2例。血小板计数均在1～2.2万之间,出血对间均延长(>20min)。血小板 Imbach et al. Reported in 1981 that intravenous injection of high-dose immunoglobulin (2 g / kg) temporarily raised platelets in children with idiopathic thrombocytopenic purpura (1TP). The authors report that the same effect was achieved by treating 4 adult ITP patients in the same way. In 4 cases, there were 2 males and 2 females, aged 15, 19, 70 and 80 years respectively. There are 2 cases of thrombocytopenia with skin and mucous membrane bleeding, thrombocytopenia 2 to 3 years without bleeding symptoms in 2 cases. Platelet counts were between 1 to 22,000, bleeding between were extended (> 20min). Platelets
