In thalassemia management, how should iron overload be addressed?

• A. Avoid iron chelation to prevent side effects
• B. Regular chelation therapy to monitor iron overload
• C. Ignore iron levels and continue transfusions
• D. Dietary iron restriction alone

Answer: (B)

Iron overload in thalassemia occurs because regular transfusions add more iron than the body can excrete, leading to deposition in the liver, heart, and endocrine organs. The way to address this is through regular iron chelation therapy to bind the excess iron and promote its elimination, with ongoing assessment of iron burden using tests like ferritin and liver or cardiac iron measurements (for example, MRI-based iron concentration or T2*). Dietary iron restriction alone is not sufficient because the iron from transfused red cells continues to accumulate, and the body cannot effectively shed the stored iron without chelation. Ignoring iron levels or avoiding chelation allows iron to continue damaging organs, increasing risks of liver disease, cardiomyopathy, and endocrine problems. Regular, ongoing chelation therapy remains the standard approach to prevent iron-related organ injury and improve long-term outcomes.
