title: Hyperhemolysis in sickle cell disease.
abstract: An 18-year-old female with sickle cell disease presented with thigh pain, dark urine, and hematuria within 72 hours of receiving a blood transfusion. Her clinical picture was consistent with hemolysis. Subsequent laboratory workup, however, demonstrated reticulocytopenia without evidence of an antibody-mediated transfusion reaction. As her hemoglobin continued to decrease, she was treated with IVIG and steroids for presumed hyperhemolysis. Clinicians should have a high index of suspicion for hyperhemolysis in sickle cell patients with evidence of hemolysis after a recent transfusion. Differentiating hyperhemolysis from other hemolytic syndromes is critical; transfusions in a hyperhemolytic episode can accelerate hemolysis causing life-threatening anemia.
