Abstract

The objective of this study is to evaluate the frequency of post-transfusion anti-erythrocyte allo-immunization to sickle cell patients in order to propose strategies of optimal blood safety in Coted'Ivoire. It is a prospective study (January to December 2013) of patients with major sickle cell disease enrolled in the transfusion therapy unit of the National Blood Transfusion Center (CNTS)in Abidjan. The reed blood cells have been phenotyped and compatibilized by indirect Coombs test in the ABO and Rh Kel systems. The search for irregular antibodies was performed before each transfusion episode. The incidence of post-transfusion anti-erythrocyte allo-immunization to the sickle cell disease patients were high (12/42 or 28.6%). We identified 14 allo-antibodies essentially anti-Rh specificity (12/14) with a high prevalence of anti-E allo-antibodies (6/14) and anti-C (4/14). None anti-Kel antibodies was found. This study raises the risk of allo-immunization in non-phenotyped and non-compatibilized transfusions, especially in sickle cell multitransfused. The erythrocyte phenotyping should be systematic to all major sickle cell patients.
在阿比让Côte科特迪瓦国家输血中心输血治疗部门对镰状细胞病患者进行抗红细胞异体免疫接种
本研究的目的是评估镰状细胞患者输血后抗红细胞同种异体免疫的频率,以便在科特迪瓦提出最佳血液安全策略。这是一项前瞻性研究(2013年1月至12月),纳入阿比让国家输血中心(CNTS)输血治疗单元的严重镰状细胞病患者。通过间接Coombs试验,芦苇血细胞在ABO和Rh Kel系统中进行了表型和相容性分析。在每次输血前进行不规则抗体的检测。镰状细胞病患者输血后抗同种异体免疫的发生率较高(12/42或28.6%)。我们鉴定出14种异体抗体,主要是抗rh特异性(12/14),抗e异体抗体(6/14)和抗c异体抗体(4/14)的患病率很高。未发现抗kel抗体。这项研究提高了非表型和非相容输血中异体免疫的风险,特别是镰状细胞多次输血。红细胞表型应系统的所有主要镰状细胞患者。
