Thalassemia Major: A Serious Disorder

The more severe form of the disease is thalassemia major, also called Cooley's Anemia. It is a serious disease that requires regular blood transfusions and extensive medical care.
Those with thalassemia major usually show symptoms within the first two years of life. They become pale and listless and have poor appetites. They grow slowly and often develop jaundice. Without treatment, the spleen, liver and heart soon become greatly enlarged. Bones become thin and brittle. Heart failure and infection are the leading causes of death among children with untreated thalassemia major.
The use of frequent blood transfusions and antibiotics has improved the outlook for children with thalassemia major. Frequent transfusions keep their hemoglobin levels near normal and prevent many of the complications of the disease. But repeated blood transfusions lead to iron overload - a buildup of iron in the body - that can damage the heart, liver and other organs. Drugs known as "iron chelators" can help rid the body of excess iron, preventing or delaying problems related to iron overload.
Thalassemia has been cured using bone marrow transplants. However, this treatment is possible only for a small minority of patients who have a suitable bone marrow donor. The transplant procedure itself is still risky and can result in death.

Can Thalassemias Be Prevented?

Thalassemias can't be prevented because they're inherited (passed on from parents to children). However, these bleeding disorders can be found before birth through prenatal tests. Family genetic studies may help find out whether people have missing or altered hemoglobin genes that cause thalassemias. (For more information, see "How Are Thalassemias Diagnosed?") If you know of family members who have thalassemias and you're thinking of having children, consider talking with your doctor and/or a genetic counselor. They can help determine your risk for passing on the disorder to your child.

What do we know about heredity and thalassemia

Thalassemia is a group of inherited or genetic diseases that affect the body's ability to produce hemoglobin, usually resulting in anemia. Hemoglobin, a protein found in red blood cells, is necessary for carrying oxygen throughout the body. Thalassemia is passed to children by parents who carry the gene for the disease. There are many different types of thalassemia, ranging from mild to life-threatening or fatal without blood transfusions and appropriate treatment. Thalassemia trait, also known as Mediterranean anemia, is one of the most common genetic disorders. Rarely resulting in illness, it affects hundreds of millions of people around the world. Each year about 100,000 babies are born with severe forms of thalassemia. The disease occurs most often in people of Italian, Greek, Middle Eastern, South and Southeast Asian, and African ancestry. The type and severity of the illness is determined by the specific genetic abnormality present. Today, better understanding of the ca...

Innovations and Research

As one of five thalassemia centers in the United States designated by the National Institutes of Health, the Children's Hospital Boston thalassemia program provides patients with access to experts in the field and the most cutting-edge clinical trials available in the world. One promising recent study, now awaiting approval by the FDA, tested the effectiveness of a new oral iron chelator, deferisirox. Researchers from Children's Hospital Boston have been at the forefront of thalassemia research and treatment for decades. Important advances in the field that were made here include: • Recognition of the important role of hypertransfusion by Dr. David Nathan, Senior Associate in Hematology, in the 1960s. • Demonstration of effective iron chelation by subcutaneous pump deferoxamine (Desferal ®) by Dr. Richard Proper and David Nathan in the 1970s. • Elucidation of the molecular biology of thalassemia syndromes by Drs. Nathan, YW Kan, Stuart Orkin and others.
