Iron burden in sickle cell anemia.
Total body iron burden was estimated by two indirect methods in 23 patients with sickle cell anemia. Concentrations of serum ferritin correlated directly and significantly with age of the patients. Eleven of 15 patients under 20 years of age had normal levels of serum ferritin. Deferoxamine-induced urinary excretion of iron was considerably less than that reported in patients with thalassemia major who were receiving regular blood transfusions. These data imply that patients with sickle cell anemia generally do not acquire excessive iron burdens during the first two decades of life. The risks of transfusional hemosiderosis in patients with sickle cell anemia who are included in hypertransfusion programs are discussed.
