Cooley anemia

In the treatment of poisoning by lead or other metal ions, higher concentrations of chelant can be safely obtained in humans by administering Na2CaEDTA rather than Na EDTA. The metal ion is bound by displacing small amounts of Ca " that the body can tolerate. Use of Na EDTA would result in calcium chelation and thus serious depletion of calcium in the body fluids (44). Removal of iron in Cooley s anemia is accompHshed by using chelants that are relatively specific for iron (45).

The use of chelating or complexing agents to treat metabolic dysfunction. The classical example is the use of D-penicillamine to treat Wilson s disease, which is caused by an inability of the body to metabolize copper in the normal way. Another example is the use of desferrioxamine for iron overload in Cooley s anemia, which is caused by a fault in hemoglobin synthesis.

P -Thaiassemia (p-Thaiassemia Major). Sometimes called Cooley s anemia after the physician who in 1925 first described the condition in the children of Italian and Greek immigrants in New York by noting that these children failed to grow, had frequent infections, appeared pale and malnourished, had splenomegaly, and had facial bone changes.

Cooley s Anemia is a genetic disorder relatively rare in the United States, but found more often among peoples of the Mediterranean area and within a band extending through India and southeast Asia ( 1 ). In addition to severe anemia, the disease causes bone malformation and general deterioration and distruction of the vital organs leading eventually to death. 

Several powerful iron chelators, some recently synthesized specifically for the Cooley s Anemia program, are being tested to ascertain their potential as drugs for use in iron chelation therapy for treating iron overload in Cooley s Anemia. Some of the more promising ones include ...

Characteristics of the more common /3-thalassemia syndromes are summarized in Table 28-4. Not included are two different abnormal heterozygotes. Anemia results from precipitation of excess a-globin chains, premature red cell destruction in bone marrow and the circulation, and deficiency of functional hemoglobin tetramer. /S-Thalassemia major, or Cooley s anemia, occurs when /3-globin synthesis is markedly depressed or absent. The ineffective erythropoiesis causes massive erythroid proliferation, skeletal deformities, and extramedullary erythropoiesis. The usual treatment is frequent blood transfusion.
