Fig. 2 Suggested algorithm for the use of iron chelators in MDS patients. *Contraindications to deferasirox include: creatinine clearance<40ml/min or serum creatinine more than twice the upper limit of normal, platelet counts <50×109/L, severe hepatic impairment (Child–Pugh class C) and hypersensitivity to deferasirox. *Contraindications to deferoxamine include: severe renal failure or anuria, Clcr<10ml/min and hypersensitivity to deferoxamine.
