Abstract
Delayed haemolytic transfusion reactions (DHTRs) are seen more frequently in patients with sickle cell disease (SCD) than in other groups of patients, and are characterised by a positive direct antiglobulin test and the appearance of previously undetected red blood cell (RBC) alloantibodies in the patient's serum. Recently a syndrome of post-transfusion hyperhaemolysis has been described in children with SCD, characterised by destruction of both autologous and transfused RBCs with negative serological findings: continuation of RBC transfusion exacerbated haemolysis further. We describe a case of life-threatening post-transfusion hyperhaemolysis in an adult patient with SCD in whom severe anaemia necessitated further RBC transfusion, which was successfully performed in conjunction with intravenous immunoglobulin. This approach may be useful in the management of post-transfusion hyperhaemolysis in SCD as well as in the management of severe DHTRs.
