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.

Thalassemia Minor: Understanding the Silent Carrier

Introduction: Thalassemia is a genetic blood disorder characterized by abnormal hemoglobin production, leading to anemia. Thalassemia minor, also known as thalassemia trait or carrier state, is the mildest form of thalassemia. Individuals with thalassemia minor typically have one normal hemoglobin gene and one mutated hemoglobin gene. Although it is considered a mild condition, understanding thalassemia minor is crucial due to its implications for genetic counseling and potential complications during pregnancy. Genetic Basis and Inheritance: Thalassemia minor is inherited in an autosomal recessive manner, meaning that both parents must carry the gene mutation for their child to have thalassemia minor. The mutated genes affect the production of either the alpha or beta globin chains that make up hemoglobin, the protein responsible for carrying oxygen in the blood. The severity of thalassemia is influenced by the specific gene mutation and the extent to which the normal gene is affected....

Beta Thalassemias

Two genes (one from each parent) are needed to make enough beta globin protein chains. If one or both of these genes are altered, you will have beta thalassemia. This means that you don't make enough beta globin protein. If you have one altered gene, you're a carrier. This condition is called beta thalassemia trait or beta thalassemia minor. It causes mild anemia. If both genes are altered, you will have beta thalassemia intermedia or beta thalassemia major (also called Cooley's anemia). The intermedia form of the disorder causes moderate anemia. The major form causes severe anemia.

Living With Thalassemias

Survival and quality of life are now much better for people who have moderate or severe forms of thalassemia. This is because: * More people are able to get blood transfusions now. * Blood screening has reduced the number of infections from blood transfusions. Also, treatments for other kinds of infections have improved. * New iron chelation treatments are available that are easier for some people to take. * Some people have been cured through blood and marrow stem cell transplants. Living with thalassemia can be challenging, but several approaches can help you cope. Follow Your Treatment Plan It's important to follow the treatment plan your doctor gives you. Get blood transfusions as he or she recommends. Take your iron chelation medicine. This is important because the leading cause of death among people with thalassemias is heart disease caused by iron overload. Iron buildup can damage your heart, liver, and other organs. Although the iron chelation treatment can ...
