End-stage liver disease (ESLD) patients undergoing liver transplant (LT) surgery are often multiply alloimmunized and pose significant challenges to the transfusion services in terms of red cell cross-match incompatibility, unpredictable blood requirements, and often lead to significant delays in availing compatible red cell units. We report a case of a 64-year-old female from Bahrain, a known case of hepatitis C-related ESLD referred for LT surgery. She had a history of multiple uneventful transfusions in the preceding year. Her blood group was A-positive, direct antiglobulin test, and cold antibodies were negative. Indirect antiglobulin test was positive, and antibody identification confirmed the presence of anti-C, anti-e, and anti-K. Her red cell phenotype was RR and Kell negative (C-c+E+e-K-). The patient was started on erythropoietin. Requests for RR and Kell negative units were sent to various blood banks across the country. After >800 A/O group units phenotyping and a waiting period of 6 weeks, two compatible RR phenotypes and Kell negative could be arranged in-house and three units were received from Gurgaon, North India. Intraoperative management included blood preservation techniques including cell salvage, antifibrinolytic drug, and monitoring using thromboelastography. The estimated blood loss was 350 ml with pre- and postoperative Hb 10.4 gm% and 9.2 gm%, respectively. She received intraoperatively two units of single-donor platelet and four units of fresh frozen plasma and postoperatively one unit of leukocyte-depleted-packed red cells and doing well at 12-month follow-up. This case highlights the importance of advance immunohematology for timely detection of alloimmunization and providing antigen-negative compatible units, proper communication between the transfusion specialists, and the clinical team for proper patient blood management as well as the need for central rare donor registry program to avoid delays in providing compatible blood in such inevitable cases.
接受肝移植(LT)手术的终末期肝病(ESLD)患者通常存在多种同种免疫情况,在红细胞交叉配血不相容、血液需求难以预测方面给输血服务带来重大挑战,并且常常导致获取相容红细胞单位的显著延迟。我们报告一例来自巴林的64岁女性病例,她是一名已知的丙型肝炎相关ESLD患者,因LT手术前来就诊。她在前一年有多次平安输血史。她的血型为A阳性,直接抗球蛋白试验及冷抗体均为阴性。间接抗球蛋白试验呈阳性,抗体鉴定证实存在抗-C、抗-e和抗-K。她的红细胞表型为RR且Kell阴性(C-c+E+e-K-)。该患者开始使用促红细胞生成素。向全国各血库发送了对RR且Kell阴性单位的需求。在对800多个A/O组单位进行表型分析并等待6周后,医院内部可以安排两个相容的RR表型且Kell阴性的单位,另外三个单位从印度北部的古尔冈接收。术中管理包括血液保存技术,如细胞回收、抗纤溶药物以及使用血栓弹力图进行监测。估计失血量为350毫升,术前和术后血红蛋白分别为10.4克%和9.2克%。她术中接受了两单位单供体血小板和四单位新鲜冰冻血浆,术后接受了一单位去白细胞红细胞悬液,在12个月的随访中情况良好。该病例强调了先进免疫血液学对于及时检测同种免疫和提供抗原阴性相容单位的重要性,输血专家与临床团队之间为妥善进行患者血液管理而进行的适当沟通,以及建立中央稀有供体登记项目以避免在此类不可避免的情况下提供相容血液出现延迟的必要性。
