In addition, the increased iron load in the blood from chronic RBC transfusions exceeds the binding capacity of transferrin and other binding proteins, leading to non- transferrin-bound iron (NTBI) [2]. So I could never comply. Chelating agents are usually organic compounds (a compound that contains carbon). The most recent BCSH guidelines continue to recommend this as first line treatment.

The objective of iron chelation is to avoid the complications of iron overload such as cardiac and hepatic dysfunction. Chelation therapy significantly improves myocardial T2* (a magnetic resonance technique for assessing tissue iron concentration) and left ventricular function. [ 33, 34] In November 2005, Deferasirox (Exjade®,ICL670) a novel, once-daily oral iron chelatorreceived approval from the US FDA and Swiss-medic for the first-line treatment of chronic ironoverload due to blood transfusions (transfusionalhemosiderosis) in adult and pediatric patients(aged 2 years and over).
