最近一些报道介绍了免疫性血小板减少性紫癜(ITP)时静注免疫球蛋白(IVIg)对升高血小板数有疗效。不仪在儿童而且在成人的急性及慢性ITP和免疫性嗜中性白细胞减少症时均观察到这种疗效。血小板或嗜中性白细胞数增加可能是一过性的,但有些患者可能从这种治疗中获得明显的长期效果。毒性极小,部分作用机制似与网状内皮细胞的FC受体封闭有关。 Recent reports have described the efficacy of intravenous immunoglobulin (IVIg) in increasing platelet count in immune thrombocytopenic purpura (ITP). This effect was observed not only in children but also in acute and chronic ITP and immune neutropenia in adults. Increased platelets or neutrophils may be transient, but some patients may have significant long-term effects from this treatment. Toxicity is very small, part of the mechanism of action and the reticuloendotheliocyte FC receptor blocking.
