An allergic transfusion reaction is when a blood transfusion results in allergic reaction. It is among the most common transfusion reactions to occur. Reported rates depend on the degree of active surveillance versus passing reporting to the blood bank. [1] [2] Overall, they are estimated to complicate up to 3% of all transfusions. [3]
TA-GvHD can develop two days to six weeks after the transfusion. [4] Typical symptoms include: [4] fever; erythematous maculopapular rash, which can progress to generalised erythroderma; toxic epidermal necrolysis in extreme cases; hepatomegaly; diarrhea; Other symptoms can include cough, abdominal pain, dyspnea and vomiting. [5]
Signs and symptoms can take as long as 14 days after exposure to appear. [2] They may include signs and symptoms commonly associated with hypersensitivity or infections. Common symptoms include: rashes and redness. [3] itching and urticaria. [2] joint pain , especially in finger and toe joints. [2] [3] fever, usually appears before rash.
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]
Side effects include iron overloading, [12] [4] [9] [13] [5] allergic reactions that lead to skin rashes and infections transmitted through transfusion. [ 4 ] [ 12 ] The most common side effect is iron overloading, which the severity of overload depends on the frequency, volume, and the amount of blood transfused to the patient. [ 9 ]
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]
Therefore, neurological signs are not lateralised to one side of the body. In the severe form of cerebral edema, a person may become unresponsive. Petechiae rash usually happens in 50% of the patients. Such skin manifestation is temporary and can disappear within one day. [6] The fat embolism syndrome can be divided into three types: [5]
Intravenous iron infusions can cause skin rash, hives, itchiness and flush. Skin staining and discolouration can occur at the site of infusion if the iron and saline solution leaks outside the vein into the surrounding tissue. [14] Skin discolouration can be semi-permanent or permanent.
