AM23-MN-03-O - AM23-MN-03-O: Hyperhemolysis Syndrome: Recognition and Current Management Strategies of a Potentially Fatal Transfusion Complication (Enduring)


Expiration Date: Dec 31, 2025


Credits: None available.

Hyperhemolysis syndrome (HHS) is an uncommon but life-threatening complication of transfusion that classically occurs in patients with sickle cell anemia but may also be seen in patients without hemoglobinopathies. Recognition of HHS is critical for appropriate management but can be challenging. The first speaker of this session—a transfusion medicine specialist—will present a systematic review of published HHS cases, articulating the epidemiological, clinical, and laboratory features of HHS and patient outcomes, including in obstetric patients. While evidence-based guidelines for managing HHS are lacking, varied and emerging strategies have been described, such as corticosteroids, intravenous immune globulin, eculizumab, and tocilizumab. The second speaker of this session—a pediatric hematologist-oncologist and transfusion medicine specialist—will present the proposed pathophysiological mechanisms of HHS and an appraisal of current management strategies.


Learning Objectives:

  • Define the diagnostic and clinical features of hyperhemolysis syndrome (HHS)
  • Examine the transfusion considerations in patients with acute HHS or a history of HHS
  • Discuss the role of immunomodulatory therapies for refractory HHS
