Iron burden in sickle cell anemia. 1978

R T O'Brien

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.

UI	MeSH Term	Description	Entries
D007501	Iron	A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN.	Iron-56,Iron 56
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011485	Protein Binding	The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.	Plasma Protein Binding Capacity,Binding, Protein
D001822	Body Burden	The total amount of a chemical, metal or radioactive substance present at any time after absorption in the body of man or animal.	Body Burdens,Burden, Body,Burdens, Body
D002648	Child	A person 6 to 12 years of age. An individual 2 to 5 years old is CHILD, PRESCHOOL.	Children
D002675	Child, Preschool	A child between the ages of 2 and 5.	Children, Preschool,Preschool Child,Preschool Children
D003676	Deferoxamine	Natural product isolated from Streptomyces pilosus. It forms iron complexes and is used as a chelating agent, particularly in the mesylate form.

D005293	Ferritins	Iron-containing proteins that are widely distributed in animals, plants, and microorganisms. Their major function is to store IRON in a nontoxic bioavailable form. Each ferritin molecule consists of ferric iron in a hollow protein shell (APOFERRITINS) made of 24 subunits of various sequences depending on the species and tissue types.	Basic Isoferritin,Ferritin,Isoferritin,Isoferritin, Basic
D006486	Hemosiderosis	Conditions in which there is a generalized increase in the iron stores of body tissues, particularly of liver and the MONONUCLEAR PHAGOCYTE SYSTEM, without demonstrable tissue damage. The name refers to the presence of stainable iron in the tissue in the form of hemosiderin.	Hemosideroses
