Despite the quite a few circumstantial variations and factors contributing to iron overload toxicity in Each and every category of transfused sufferers, each effort and hard work must be built to minimise affiliated organ damage as well as to result in a lessen in the overall morbidity and mortality. In this particular context and much like other conditions, personalised drugs depending on individualised, tailor-created, successful and safe chelation therapy protocols ought to be made for managing the varied types of transfusional iron-loaded individuals with unique charges of entire body iron ingestion [118,186,187].
