The incidence of<unk>  in immunocompromised patients receiving blood transfusions is estimated to be 0.1–1.0%, and mortality around 80–90%. Mortality is higher in<unk>  than in GvHD associated with bone marrow transplantation, where the engrafted lymphoid cells in the bone marrow are of donor origin (in autotransplant) and therefore the immune reaction is not directed against them. The most common causes of death in<unk>  are infections and hemorrhages secondary to pancytopenia and liver dysfunction.
