the probability of hypersplenism. Those undergoing splenectomy should receive an appropriate pneumococcal vaccine at least one week (preferably three weeks) before the surgery. Therapeutic Long-term transfusion therapy (in those with transfusion dependent beta thalassemia) is a treatment used to maintain hemoglobin levels at a target pre-transfusion hemoglobin level of 9–10.5 g/dL (11-12 g/dL in those with concomitant heart disease). To ensure quality blood transfusions, the packed red blood cells should be leucoreduced. By having leucoreduced blood packets, the patient is at a lower risk to develop adverse reactions by contaminated white cells and preventing platelet alloimmunisation. Patients with allergic transfusion reactions or unusual red cell antibodies must receive washed red cells or cryopreserved red cells. Washed red cells have been removed of plasma proteins that would have become a target of the patient's antibodies allowing the transfusion to be carried out safely. Cryopreserved red cells are used to maintain a supply of rare donor units for patients with unusual red cell antibodies or missing common red cell antigens. These regular transfusions promote normal growth, physical activities and suppress bone marrow hyperactivity. Pharmaceutical During normal iron homeostasis the circulating iron is bound to transferrin. But with iron overload (such as with frequent blood transfusions), the ability for transferrin to bind iron is exceeded and non-transferrin bound iron accumulated. This unbound iron is toxic due to its high propensity to induce oxygen species and is responsible for cellular damage. The prevention of iron overload protects patients from morbidity and mortality. The primary aim is to bind to and remove iron from the body and a rate equal to the rate of transfusional iron input or greater than iron input. Iron chelation is a medical therapy that may prevent the complications of iron overload. Every unit of transfused blood contains 200–250 mg of iron and the body has no natural mechanism to remove excess iron. The excess iron can be removed by iron chelators (deferoxamine, deferiprone and deferasirox). Luspatercept (ACE-536) is a recombinant fusion protein that is used as a treatment in adults with transfusion dependent beta thalassemia. It consists of a modified extra-cellular domain of human activin receptor type IIB bound to the Fc portion of the human IgG1 antibody. The molecule binds to select transforming growth factor beta superfamily ligands to block SMAD2 and 3 signaling, thus enhancing erythroid maturation. The medication has been shown to reduce the transfusion burden by
