Thalassemia is a genetic blood disorder that affects the production of hemoglobin, the protein in red blood cells that carries oxygen. People with thalassemia have either reduced or abnormal hemoglobin production, leading to anemia and other complications. There are different types of thalassemia, including alpha thalassemia and beta thalassemia, with varying degrees of severity. Treatment for thalassemia may include blood transfusions, iron chelation therapy, and in some cases, bone marrow transplantation.

SAQ on Thalassemia
Q1. What is thalassemia?
A1. Thalassemia is a genetic blood disorder characterized by reduced or absent production of one or more globin chains of hemoglobin, leading to abnormal hemoglobin formation and red blood cell dysfunction.
Q2. What are the different types of thalassemia?
A2.
- Alpha thalassemia: Reduced or absent production of alpha-globin chains.
- Beta thalassemia: Reduced or absent production of beta-globin chains.
- Delta thalassemia: Reduced or absent production of delta-globin chains.
- Gamma thalassemia: Reduced or absent production of gamma-globin chains.
Q3. What are the clinical manifestations of thalassemia?
A3. Clinical manifestations vary depending on the type and severity of thalassemia:
- Alpha thalassemia: Mild or no symptoms.
- Mild beta thalassemia: Anemia, fatigue, weakness.
- Moderate beta thalassemia (thalassemia intermedia): Severe anemia, enlarged spleen, growth problems.
- Severe beta thalassemia (thalassemia major): Severe anemia, bone deformities, growth failure, intellectual disability.
- Delta/gamma thalassemia: Mild or no symptoms.
Q4. How is thalassemia diagnosed?
A4.
- Complete blood count (CBC) showing anemia and abnormal red blood cell morphology.
- Hemoglobin electrophoresis or high-performance liquid chromatography to analyze hemoglobin patterns.
- Genetic testing to confirm the specific type of thalassemia.
Q5. What are the treatment options for thalassemia?
A5.
- Blood transfusions to manage anemia.
- Iron chelation therapy to prevent iron overload from repeated transfusions.
- Bone marrow transplant for severe cases.
- Gene therapy (research stage).
