  • Title: Multiple hemolytic transfusion reactions misinterpreted as severe vaso-occlusive crisis in a patient with sickle cell disease.
    Author: Dean CL, Maier CL, Roback JD, Stowell SR.
    Journal: Transfusion; 2019 Feb; 59(2):448-453. PubMed ID: 30412270.
    Abstract:
    BACKGROUND: Hemolytic transfusion reactions are a rare, yet serious complication of red blood cell (RBC) transfusion. Patients with sickle cell disease (SCD) are at an increased risk for such reactions, because they are prone to make alloantibodies against transfused RBCs, complicating this integral part of their disease management. These reactions may be missed, and the patient's state may be attributed to vaso-occlusive crisis (VOC), with misguided therapy ensuing. CASE REPORT: Herein, we report the clinical course of a patient with complex SCD with a delayed hemolytic transfusion reaction, followed by multiple acute hemolytic transfusion reactions mistaken for severe VOC. These reactions were diagnosed on retrospective review of the patient's clinical course in consult with the transfusion medicine service. Optimal immunosuppressive therapy ensued and resulted in the stabilization of the anemia and hemolysis laboratory values. Despite these efforts, the patient died 2 months after admission. CONCLUSION: This case provides insight into some of the challenges of managing patients with SCD with multiple comorbidities. Hemolytic transfusion reactions can be difficult to diagnose and may be overlooked in patients with SCD with severe VOC.
