Transfusion-related immune modulation has been thought to be the underlying mechanism. [6] Washing red cells has been thought to be one way of potentially decreasing the risk of theses transfusion-related side-effects. [6] However, in neonates, there is insufficient evidence to say whether washing red cells has any effect. [6]
The primary method to treat transfusion-dependent anemia is by transfusing packed red blood cells. [9] Transfusion is also one of the treatment strategies for beta-thalassemia patients and patients with myelodysplastic syndrome (MDS). [13] Although transfusion of red blood cells cannot correct the underlying problems, it can improve anemia ...
The body has limited ways to store and remove iron. When red blood cells (RBCs) die, they are consumed by macrophages. Transfused RBCs have shorter lifespans that native ones, so they die and are consumed more frequently by the macrophages, which causes the latter to die from excess iron which is then released into the blood.

In transfusion medicine, transfusion-associated circulatory overload (aka TACO) is a transfusion reaction (an adverse effect of blood transfusion) resulting in signs or symptoms of excess fluid in the circulatory system (hypervolemia) within 12 hours after transfusion. [2]
Red blood cell concentrates, also known as red cell concentrates or packed red blood cells, are red blood cells that have been separated for blood transfusion. [1] A red blood cell concentrate typically has a haematocrit of 0.50 – 0.70 L/L and a volume between 250 and 320 mL.
Iron is involved in key bodily processes, including the transportation of oxygen in the blood. It also plays a central role in building energy and proteins, and it can be found in your red blood ...
For those with severe forms of thalassemia (thalassemia major, or transfusion-dependent thalassemia), the three principal treatments are red blood cell transfusions to relieve anemia, iron chelation to mitigate the side effects of transfusion, and folic acid supplementation to encourage the growth of new blood cells.

A gene-editing therapy for sickle cell disease, with a price tag of £1.65m, is to be offered to patients on the NHS in England. About 50 people a year with the inherited blood disorder are likely ...
