Autoimmune diseases are rare in patients with severe combined immunodeficiency (SCID). The authors describe an 11-month-old infant girl with SCID with fatal warm autoimmune hemolytic anemia (AIHA) resulting from IgM autoagglutinins. Serologic evaluation revealed IgM autoantibodies that caused in vitro hemagglutination at 37°C. The patient had clinical evidence of ongoing hemolysis and agglutination despite aggressive treatment. She had three strokes and died 6 weeks after unsuccessful bone marrow transplantation. Autoimmune disease is an unexpected complication of SCID. The presence of warm reactive IgM autoagglutinins in AIHA confers a dismal prognosis.
