Abstract
- Thalassemia is a blood disorder that affects the production of hemoglobin (Hb), the crucial protein responsible for carrying and delivering oxygen to tissues. It is caused by mutations in the genes that control the production of hemoglobin, leading to decreased or absent production of one of the globin chains (alpha or beta) that make up hemoglobin. Individuals with thalassemia often need regular blood transfusions to maintain adequate Hb levels. However, frequent transfusions can cause iron overload in the body, necessitating chelation therapy to remove excess iron and prevent organ damage. The iron overload also results in higher levels of hemolysis, leading to the release of free acellular Hb and heme, which the body's natural scavenging proteins (hemopexin and haptoglobin) cannot effectively handle.
