A person with thalassemia will have too few red blood cells and too little hemoglobin, and the red blood cells may be too small. Around , newborns are delivered each year with severe forms of thalassemia. It is most common with Mediterranean, South Asian, and African ancestry.

Thalassemias

Thalassemias are a group of blood disorders that affect the way the body makes hemoglobin. Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body. It's made up of alpha globin and beta globin. The body contains more red blood cells than any other type of cell, and each has a life span of about 4 months. Each day, the body produces new red blood cells to replace those that die or are lost from the body.

Beta-thalassemia BT intermedia is a form of BT see this term characterized by mild to moderate anemia which does not or only occasionally requires transfusion. Annual incidence of BT intermedia is not known. BT intermedia encompasses a wide clinical spectrum with more severe cases presenting between 2 and 6 years of age with anemia, spleen and sometimes liver enlargement, as well as delayed growth and development.

Thalassemias are a group of inherited microcytic, hemolytic anemias characterized by defective hemoglobin synthesis. Alpha-thalassemia is particularly common among people of African, Mediterranean, or Southeast Asian ancestry. Symptoms and signs result from anemia, hemolysis, splenomegaly, bone marrow hyperplasia, and, if there have been multiple transfusions, iron overload. Diagnosis is based on genetic tests and quantitative hemoglobin analysis. Treatment for severe forms may include transfusion, splenectomy, chelation, and stem cell transplantation. See also Overview of Hemolytic Anemia. Thalassemia is a hemoglobinopathy that is among the most common inherited disorders of hemoglobin production.

Thalassemia

Thalassemia is an inherited blood disorder in which the body makes an abnormal form of hemoglobin. Hemoglobin is the protein molecule in red blood cells that carries oxygen. The disorder results in excessive destruction of red blood cells, which leads to anemia. Thalassemia is inherited, meaning that at least one of your parents must be a carrier of the disorder. Thalassemia minor is a less serious form of the disorder. There are two main forms of thalassemia that are more serious. In alpha thalassemia, at least one of the alpha globin genes has a mutation or abnormality.

Most children with moderate to severe thalassemia show signs and symptoms within their first two years of life. If your doctor suspects your child has thalassemia, he or she can confirm a diagnosis with blood tests. Blood tests can reveal the number of red blood cells and abnormalities in size, shape or color. Blood tests can also be used for DNA analysis to look for mutated genes. Testing can be done before a baby is born to find out if he or she has thalassemia and determine how severe it might be.


Causes. The protein hemoglobin transports oxygen around the body in blood cells. Bone marrow uses the iron we get from food to make.

Beta-thalassemias are a group of hereditary blood disorders characterized by anomalies in the synthesis of the beta chains of hemoglobin resulting in variable phenotypes ranging from severe anemia to clinically asymptomatic individuals. The total annual incidence of symptomatic individuals is estimated at 1 in , throughout the world and 1 in 10, people in the European Union. Three main forms have been described: thalassemia major, thalassemia intermedia and thalassemia minor.

Thalassemia

Она наклонилась и что было сил потянула ее, стараясь высвободить застрявшую часть. Затуманенные глаза Беккера не отрываясь смотрели на торчащий из двери кусок ткани. Он рванулся, вытянув вперед руки, к этой заветной щели, из которой торчал красный хвост сумки, и упал вперед, но его вытянутая рука не достала до. Ему не хватило лишь нескольких сантиметров.

 Директор, Стратмору не удается отключить ТРАНСТЕКСТ. - Что?! - хором вскричали Бринкерхофф и Фонтейн.

Alpha thalassemia occurs when the body can't make alpha globin. In order to make alpha globin, you need to have four genes, two from each parent. This type of thalassemia also has two serious types: hemoglobin H disease and hydrops fetalis.
