HIV infection presenting as severe autoimmune hemolytic anemia with disseminated intravascular coagulation in an infant.

Autoimmune hemolytic anemia is rare in children. It is generally diagnosed in relation to a viral or bacterial infection but has also been described in association with drugs, autoimmune disease, malignancy, and immunodeficiency. The authors describe a 5-month-old infant who presented with severe autoimmune hemolytic anemia and disseminated intravascular coagulation as his initial manifestation of HIV infection.
