What causes splenomegaly in beta thalassemia?
An enlarged spleen in individuals with beta thalassemia may occur due to increased destruction of red blood cells, the formation of blood cells outside of the bone marrow (extramedullary hematopoiesis), repeated blood transfusions, or iron overload.
What is the difference between beta thalassemia and thalassemia?
When thalassemia is called “alpha” or “beta,” this refers to the part of hemoglobin that isn’t being made. If either the alpha or beta part is not made, there aren’t enough building blocks to make normal amounts of hemoglobin. Low alpha is called alpha thalassemia. Low beta is called beta thalassemia.
How long do beta thalassemia patients live?
Survival of thalassemia patients The cumulative survival rate from birth until 10 years old was 99%. After reaching the age of 20 years, 88% of the patients survived until 30 years, 74% survived until 45, 68% survived until 50, and 51% survived until 55 years old.
What is β thalassemia disease?
What is beta thalassemia? Thalassemia (thal-uh-SEE-mee-uh) is a blood disorder that is inherited. This means it is passed down from one or both parents through their genes. When you have thalassemia, your body makes less hemoglobin than normal. Hemoglobin is an iron-rich protein in red blood cells.
Why does thalassemia cause jaundice?
Individuals with thalassemia have hyperbilirubinemia secondary to ongoing hemolysis and ineffective erythropoiesis. Iron loading occurs because of increased iron absorption as well as the administration of blood transfusions.
Why is RBC high in thalassemia?
The diagnosis often is one of exclusion of other causes of microcytic anemia. In beta-thalassemia major, anemia is severe, often with hemoglobin ≤ 6 g/dL (≤ 60 g/L). Red blood cell count is elevated relative to hemoglobin because the cells are very microcytic.
Can beta thalassemia be cured?
Blood transfusions and chelation do not cure beta thalassemia. A stem cell transplant can cure it, but it is a serious procedure with many risks and won’t benefit everyone with the condition. Doctors and scientist are working on developing gene therapies and other treatments to help people with beta thalassemia.
Can thalassemia patients marry?
Aim: With good care, patients with transfusion-dependent thalassemia major (TDTM) can reach older ages, marry and reproduce.
How is beta thalassemia treated?
Treatment for beta thalassemia may include:
- Regular blood transfusions.
- Medications (to decrease amount of iron in the body, called chelation therapy)
- Surgical removal of the spleen (if necessary)
- Daily doses of folic acid.
- Possible surgical removal of the gallbladder.
- No iron supplements.
- Bone marrow transplantation.
