背景 ABO不相容可导致器官移植后24～48小时内发生超急性血液排斥。对抗原浓度很低(A_2代替A_1)以及移植前血浆置换(PE)降低受体抗A水平的患者,已成功地进行肾移植。对于尽管在移植前进行了彻底的PE但抗A水平依然很高的患者,作者通过静脉内输注免疫球蛋白(IVIg)来降低其抗A水平。病例报道 一例38岁患糖尿病、视网膜病、肾衰竭、高血压及心 Background ABO Incompatibility can lead to hyperacute blood rejection within 24 to 48 hours after organ transplantation. Kidney transplantation has been successfully performed in patients with very low antigen concentration (A_2 instead of A_1) and pre-transplant plasma exchange (PE) with reduced anti-A receptor levels. For patients who are resistant to A levels despite intravenous infusion of immunoglobulin (IVIg) despite a thorough PE prior to transplantation, the authors reduced their anti-A levels.
