红细胞输注仍然是治疗镰状细胞病急性和慢性并发症的关键组成部分。随机临床试验证明了输血治疗对预防原发性和继发性中风以及术后急性胸部综合征的益处。脾隔离症、急性胸部综合征和急性中风的输血由专家共识建议指导。尽管血液库存安全性总体有所改善,但输血的不良反应在镰状细胞病患者中普遍存在,包括同种免疫、急性和迟发性溶血性输血反应以及铁过载。明智地使用红细胞输注、优化红细胞抗原匹配以及使用红细胞分离术和铁螯合可以最大限度地减少不良反应。溶血性输血反应的早期识别和处理可以避免不良的临床结局。在这篇综述中,我们讨论了镰状细胞病的输血方法,适应症和并发症,重点是同种免疫。
Red cell transfusion remains a critical component of care for acute and chronic complications of sickle cell disease. Randomized clinical trials demonstrated the benefits of transfusion therapy for prevention of primary and secondary strokes and postoperative acute chest syndrome. Transfusion for splenic sequestration, acute chest syndrome, and acute stroke are guided by expert consensus recommendations. Despite overall improvements in blood inventory safety, adverse effects of transfusion are prevalent among patients with sickle cell disease and include alloimmunization, acute and delayed hemolytic transfusion reactions, and iron overload. Judicious use of red cell transfusions, optimization of red cell antigen matching, and the use of erythrocytapheresis and iron chelation can minimize adverse effects. Early recognition and management of hemolytic transfusion reactions can avert poor clinical outcomes. In this review, we discuss transfusion methods, indications, and complications in sickle cell disease with an emphasis on alloimmunization.
