肝移植已经成为治疗终末期肝病的首选治疗方法,肝脏作为1种免疫特惠性器官,对抗体介导的排斥反应有较好的耐受性,迄今已有很多人接受了血型不相合的肝移植术,且术后生存率逐步提高。但在ABO非同型的肝移植中,很多患者术后血红蛋白短期内会有下降,原因是供者肝脏的“过客”B淋巴细胞分泌的血型抗体能溶解患者和(或)输入的红细胞,引起溶血反应,且轻微的溶血会被忽视,导致患者术后贫血症状加重。ABO非同型肝移植术后因过客淋巴细胞发 Liver transplantation has become the preferred treatment for end-stage liver disease. As an immunosuppressive organ, the liver is well tolerated by antibody-mediated rejection. To date, many people have undergone incompatible liver transplantation , And the postoperative survival rate increased gradually. However, in non-isotype ABO liver transplantation, many patients may experience a decrease in postoperative hemoglobin within a short period of time because the blood group antibodies secreted by the “passing” B lymphocytes of the donor’s liver can dissolve the patient and / or imported red blood cells, Cause hemolytic reaction, and mild hemolysis will be ignored, resulting in patients with postoperative anemia symptoms worse.
