Severe reactions may result in cutaneous necrosis at the injection site, typically presenting in one of two forms: (1) those associated with intravenous infusion or (2) those related to intramuscular injection. [7]: 123–4 Intramuscular injections may produce a syndrome called livedo dermatitis. [7]: 124
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]
Fever of at least 39 °C, OR a rise in temperature of at least 2 °C from pre-transfusion values AND/OR other symptoms or signs, including chills (), painful muscles (), or nausea that are severe enough that the transfusion is stopped AND requires immediate medical treatment, admission to hospital, or lengthens the duration of hospital admission.
In addition to adoptive T-cell therapies, severe CRS or cytokine reactions can occur in a number of infectious and non-infectious diseases including graft-versus-host disease (GVHD), coronavirus disease 2019 (COVID-19), acute respiratory distress syndrome (ARDS), sepsis, Ebola, avian influenza, smallpox, and systemic inflammatory response ...
An allergic reaction will not occur on the first exposure to a substance. The first exposure allows the body to create antibodies and memory lymphocyte cells for the antigen. However, drugs often contain many different substances, including dyes, which could cause allergic reactions. This can cause an allergic reaction on the first ...
Initial treatment for any type of transfusion reaction, including AHTR, is discontinuation of the transfusion. Fluid replacement and close monitoring of vital signs are important. People with AHTR are managed with supportive care , which may include diuretics , blood pressure support, and treatment of disseminated intravascular coagulation ...
The symptoms of DRESS syndrome usually begin 2 to 6 weeks but uncommonly up to 8–16 weeks after exposure to an offending drug. Symptoms generally include fever, an often itchy rash which may be morbilliform or consist mainly of macules or plaques, facial edema (i.e. swelling, which is a hallmark of the disease), enlarged and sometimes painful lymph nodes, and other symptoms due to ...
Type I hypersensitivity (or immediate hypersensitivity), in the Gell and Coombs classification of allergic reactions, is an allergic reaction provoked by re-exposure to a specific type of antigen referred to as an allergen. [1] Type I is distinct from type II, type III and type IV hypersensitivities. The relevance of the Gell and Coombs ...
