title: Management of iron overload in the pediatric patient.
abstract: Iron overload is a major complication of long-term transfusion therapy. In the absence of treatment, the excessive iron causes diffuse organ damage, usually culminating in death from heart disease. Deferoxamine, an iron-chelating drug, removes tissue iron, prevents iron-induced organ dysfunction, and prolongs life. Proper administration of deferoxamine requires careful attention to dose, route and duration of administration, and compliance. Better chelators are needed but are unlikely to be available soon. Other methods for preventing or reducing iron accumulation involve alterations in the transfusion program or the blood product. Prevention of iron overload should improve the lives of patients with transfusion-dependent anemias and extend the usefulness of transfusion in chronic hematologic disorders.
