The incidence of TA-GvHD in immunocompromised patients receiving blood transfusions is estimated to be 0.1–1.0%, and mortality around 80–90%. Mortality is higher in TA-GvHD 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 symptoms of TACO can include shortness of breath , low blood oxygen levels , leg swelling (peripheral edema), high blood pressure (hypertension), and a high heart rate (tachycardia). [ 3 ] It can occur due to a rapid transfusion of a large volume of blood but can also occur during a single red blood cell transfusion (about 15% of cases). [ 2 ]

Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).
Post-transfusion purpura (PTP) is a delayed adverse reaction to a blood transfusion or platelet transfusion that occurs when the body has produced alloantibodies to the allogeneic transfused platelets' antigens. These alloantibodies destroy the patient's platelets leading to thrombocytopenia, a rapid decline in platelet count. [1]
An acute hemolytic transfusion reaction (AHTR), also called immediate hemolytic transfusion reaction, is a life-threatening reaction to receiving a blood transfusion. AHTRs occur within 24 hours of the transfusion and can be triggered by a few milliliters of blood. The reaction is triggered by host antibodies destroying donor red blood cells.
Febrile non-hemolytic transfusion reaction (FNHTR) is the most common type of transfusion reaction. It is a benign occurrence with symptoms that include fever but not directly related with hemolysis. [1] It is caused by cytokine release from leukocytes within the donor product as a consequence of white blood cell breakdown.
Transfusion hemosiderosis can cause permanent damage to tissues that may lead to death. [2] Tissue damage can remain even after chelation therapy. [2] Outcomes are usually worse in patients who require blood transfusions compared to those who can have alternative therapies. [2] Cardiomyopathy and cardiac arrhythmia are often a cause of death.
