What are the consequences of chronic iron overload and how is it treated?

• A. Iron chelation therapy only; no organ damage
• B. Organ damage and chelation therapy (deferoxamine, deferasirox, deferiprone); ferritin monitoring
• C. No treatment needed
• D. Iron overload causes anemia; treat with iron supplements

Answer: (B)

Chronic iron overload causes iron to deposit in organs, damaging tissues and leading to serious problems such as liver cirrhosis, cardiomyopathy or heart failure, diabetes from pancreatic involvement, and other endocrine issues. Treating this condition focuses on removing the excess iron and tracking how much iron remains in the body. Iron chelation therapy uses medications like deferoxamine, deferasirox, and deferiprone to bind excess iron and help eliminate it from the body. Ferritin levels are commonly monitored to gauge iron burden and response to therapy, guiding adjustments in treatment. In transfusional iron overload, chelation is essential to prevent ongoing organ damage; in other contexts like hereditary hemochromatosis, phlebotomy may be used to reduce iron stores, but chelation remains a cornerstone for many overload scenarios. The goal is to prevent or minimize irreversible organ damage by both removing iron and closely monitoring iron stores.
