Quoted from the NIH: Normally, the immune system helps protect the body, but with Crohn's disease the immune system can't tell the difference between normal body tissue and foreign substances.

For the neonate with FMAIT, platelet transfusion is the treatment of choice and should be given to normalise the platelet count in an infant with ICH or to treat severe throbmobocytopaenia in infants without ICH. Platelets used for neonates with FMAIT should be negative for the implicated platelet-specific antigen.
Plasma donation â also known as apheresis. Plasma is separated from the other components by a special machine, and the red blood cells are returned to the donor in cycles throughout the donation. Platelet donation â known as platelet pheresis. This is done in a similar way to plasma donation, but both the red cells and plasma are returned to the donor.
