Impaired erythropoiesis and refractory anemia are clinical hallmarks
of the myelodysplastic syndromes (MDS). As the disease evolves, a
steady decline in hemoglobin in these disorders invariably results in
dependence on packed red blood cell (PRBC) transfusion. Such chronic
transfusion dependence has been associated with iron overload causing
cardio-hepatic toxicity and alloimmunization, and can result in
reduced survival in these patients. The use of hematopoietic growth
factors, particularly erythropoiesis-stimulating agents (ESAs), has
been reported to reduce the need for PRBC transfusion, raise
hemoglobin and improve quality of life, at least in patients
responding to such a therapy. Importantly, the clinical benefits of
ESA are well balanced, with an apparently favorable safety profile in
MDS, thus providing an eminent the****utic option to delay or avoid
transfusion dependence in these patients. The present report provides
a detailed comparative profile of long-term PRBC transfusions and the
balance of clinical benefits versus risks associated with ESA therapy
