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] The symptoms of TACO can include shortness of breath , low blood oxygen ...
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 ...
Transfusion hemosiderosis [1] Idiopathic pulmonary hemosiderosis; Transfusional diabetes [2] [3] Organs affected: Hemosiderin deposition in the lungs is often seen after diffuse alveolar hemorrhage, which occurs in diseases such as Goodpasture's syndrome, granulomatosis with polyangiitis, and idiopathic pulmonary hemosiderosis.
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]
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.

It is often impossible to distinguish TRALI from acute respiratory distress syndrome (ARDS). The typical presentation of TRALI is the sudden development of shortness of breath, severe hypoxemia (O 2 saturation <90% in room air), low blood pressure, and fever that develop within 6 hours after transfusion and usually resolve with supportive care within 48 to 96 hours.
GvHD can also occur after a blood transfusion, known as Transfusion-associated graft-versus-host disease or TA-GvHD if the blood products used have not been gamma irradiated or treated with an approved leukocyte reduction system. In contrast to organ/tissue transplant associated GvHD, the incidence of TA-GvHD is increased with HLA matching ...
