In severe thalassemia, what is the cornerstone of clinical intervention?

• A. Frequent blood transfusions with iron chelation as needed.
• B. Iron supplementation.
• C. Splenectomy.
• D. No treatment.

Answer: (A)

Regular, lifelong red blood cell transfusions are used to stabilize hemoglobin in severe thalassemia major. This corrects the profound anemia caused by ineffective erythropoiesis, improves growth and development, and reduces bone marrow expansion that leads to skeletal changes. That approach is the cornerstone because it directly addresses the life-threatening anemia and its systemic consequences. But each transfusion adds iron to the body, and there’s no natural way to excrete that excess. Over time, iron overload can damage the liver, heart, and endocrine glands, so iron chelation therapy is essential to prevent organ injury. Chelation is used alongside transfusions and can be given with drugs like deferoxamine, deferasirox, or deferiprone to remove the excess iron, guided by iron studies and imaging. Splenectomy may be considered in specific situations such as hypersplenism or very large spleens, but it does not solve the underlying anemia and carries risks, so it’s not the primary intervention. Iron supplementation would worsen iron overload, and doing nothing is clearly inappropriate.
