摘要

我们分析了28例abo血型不相容骨髓移植(BMT)前清除红细胞抗体的三种不同方法。6例患者接受广泛血浆置换治疗。抗体滴度从1:12 12降至1:4(中位数)。10例患者采用吸附柱体外免疫吸附法去除抗体。滴度从1:128降至1:32。在这10名患者中,有4名患者在完全去除抗体的同时加入了血浆置换。12例患者在骨髓输注前用供体型红细胞进行简单体内吸附治疗。其中8例的滴度无法检测到。讨论了这三种方法的优缺点。

ABO-incompatible bone marrow transplantation: Three methods for the removal of red blood cell antibodies

We analyzed three different methods for removing red blood cell (RBC) antibodies in 28 patients before a major ABO-incompatible bone marrow transplantation (BMT). Six patients were treated with extensive plasma exchange. Antibody titers were lowered from 1:512 to 1:4 (median values). In ten patients antibodies were removed by extracorporeal immunoadsorption using an adsorbent column. Titers decreased from 1:128 to 1:32. In four of these ten patients plasma exchange was added to complete antibody removal. Twelve patients were treated with simple in vivo adsorption with donor-type RBCs before marrow infusion. In eight of them, titers became undetectable. Advantages and disadvantages of the three methods are discussed.
