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 .
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 , 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 . 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.
