Iron toxicity in transfusion dependent DBA children remains a challenge. Iron overload from repeated transfusions is the leading cause of death in DBA patients when excluding transplant related mortality [1].

Although the trend in  ferritin levels have been used as a guide to detect iron overload, the reliability has been questioned. The study often quoted is that by Kolnagou A [2], who showed that a low serum ferritin level was not sensitive in predicting cardiac iron overload. T2* magnetic resonance imaging (MRI) is currently the gold standard investigation for iron load detection [3]. FerriScan provides an accurate, validated MRI-based measurement of liver iron concentration and is being used by leading experts globally in DBA patients.

In Africa, according to Resonance Health, FerriScan is now available in a number of our countries.

A comprehensive review of the literature with regards to iron overload in DBA will follow shortly.
