Allergic reactions to blood or blood product transfusions; Can IgA deficiency be prevented? But you can limit the spread of germs and sickness by washing your hands often and staying away from large crowds. Hemagglutination Assays for the Diagnosis and Prevention of IgA Anaphylactic Transfusion Reactions. If a person with IgA deficiency does not have any IgA, they are at an increased risk of developing an allergic reaction to blood transfusion products, and should use IgA depleted blood … Transfusion‐associated anaphylaxis has been associated with anti‐immunoglobulin A (anti‐IgA) of IgG class in patients with IgA deficiency. Estimation of the theoretical risk for IgA anaphylactic transfusion reaction was 0.009%. Most immunoglobulin replacement products on the market today have minimal amounts of IgA content and do not result in adverse events even in a patient lacking IgA. A significant number of individuals with IgA deficiency develop autoantibodies to IgA, thus there is controversy as to whether transfusion of standard blood products or IgA-deficient blood products should be administered in emergency situations such as the one in this report. 1,2 In these cases, warm IgA autoantibodies (optimal reaction at 37°C) generally have a specificity spectrum similar to that of warm IgG autoantibodies. Using PHIA to measure serum concentrations of IgA and PHA to detect IgA antibodies, we found the frequency of IgA deficiency (< 0.05 mg/dL) and class-specific anti-IgA in random blood donors to be approximately 1 in 1,200. The idea is that since a person with IgA deficiency has never seen the IgA that comes in blood transfusions, their body will treat it like a foreign protein and can have an allergic or even anaphylactic response. However, some people who have IgA deficiency experience pneumonia, ear infections, sinus infections, allergies, asthma and diarrhea. • It is associated with an increased risk of infections, allergic and autoimmune diseases, and rarely, malignancy. IgA deficiency was confirmed by an ELISA method and the presence of anti-IgA by a passive hemagglutination assay.

Four methods were compared as to their suitability for excluding IgA deficiency in the investigation of suspected anti-IgA transfusion reactions. Regarding this difference in IgA deficiency in different races and regions of the word, it seems that it is essential that blood transfusion services plan special programs to produce safe blood and components for IgA deficient consumers. The patient’s father states that she had a sore throat and runny nose one week ago. Overview. Blood 1994;84(6):2031-2035. 10. IgA Anaphylactic Transfusion Reactions • A small number of patients with selective IgA deficiency produce IgG or IgE against IgA antibodies. Some people with IgA deficiency can have more frequent sinopulmonary infections (sinus infections, bronchitis, pneumonia, etc), and are more likely to have giardia infection, and autoimmune diseases. Anti-IgA was identified in 2 of the 14 IgA-deficient blood donors whose IgA levels were <5 mg dL(-1) . • Do not lightly apply the label “IgA deficient”, as this commits the blood bank to procuring and supplying special blood products for this patient for life. C. American Red Cross maintains registry of rare confirmed IgA deficient 2. Affected persons are susceptible to adverse transfusion reactions from blood or blood products containing IgA. A recent case report described the successful management of an SIgAD patient who required massive blood transfusion during emergency cesarean delivery. Send thanks to the doctor . Transfusion 2016; 56(S4):16. The majority of patients with selective IgA deficiency undergoing transfusion of blood products are asymptomatic. Carterson A, Siberstein L, Savage W. IgA deficiency is not prevalent among patients who experience allergic transfusion reactions to platelets. Selective immunoglobulin A (IgA) deficiency (SIgAD) is a genetic immunodeficiency, a type of hypogammaglobulinemia.People with this deficiency lack immunoglobulin A (IgA), a type of antibody that protects against infections of the mucous membranes lining the mouth, airways, and digestive tract. Selective deficiency of serum IgA is the most common immunodeficiency in humans; when immunodeficient individuals receive blood transfusions a severe anaphylactoid reaction can develop. iga deficiency danger of anaphilaxis to blood transfusion..?

IgA deficiency is a problem that may be passed down through your family, so you can’t do anything to prevent it. Parallel testing was performed on sera from 40 patients or blood donors previously … • There is a risk of transfusion reactions due to the rare development of IgE against IgA in blood products. In our case, IgA-deficient FFP was not immediately available. Red cells are washed to provide IgA deficient product. Although it is difficult to develop a suitable file of IgA‐deficient donors in Japan, the establishment of a Rare Donor Registry System on IgA deficiency is a matter of urgency. However, in the subset of patients in whom anti-IgA antibodies are formed, anaphylactic reaction to blood products may occur. Selective IgA deficiency is a common immunodeficient state that occurs in healthy individuals with a frequency ranging from 1:700 1 to 1:3,040 2, depending on population selection and diagnostic criteria.Selective IgA deficiency is associated also with a variety of clinical disorders, including chronic respiratory, 3-5 gastrointestinal, 6-8 and autoimmune diseases. B. IgA deficiency should be considered in patients with anaphylactic reactions to transfusion. avoid blood transfusions unless treated with saline wash or from IgA deficient individual ; Complications . Individuals with this condition have a complete absence or severe deficiency of IgA, which is essential in the respiratory and gastrointestinal tracts and plays a role in developing mucosal immunity and protection against infection.

Deficiency of IgA is a primary immune deficiency found most frequently in persons of European descent (1 in 700). Medical charts of recipients were reviewed for the occurrence of a suspected transfusion reaction. After the transfusion reaction a hemagglutination inhibition assay revealed that her blood contained less than 1.0 micrograms/ml of IgA and an anti-IgA antibody … If transfusion of red blood cells (RBCs) is needed, only washed packed RBCs can be used. The methods were radial immunodiffusion, passive hemagglutination inhibition, sandwich enzyme-linked immunosorbent assay, and membrane enzyme immunoassay. Selective IgA deficiency is an immune system condition in which you lack or don't have enough immunoglobulin A (IgA), a protein that fights infection (antibody).Most people with selective IgA deficiency don't have recurrent infections.

New data quantify the risk of allergic reactions in recipients of blood components containing anti-IgA (ie, blood donated by SIgAD donors). IgA class antibodies are present in approximately 14% of patients with warm-type autoimmune hemolytic anemia (wAIHA) and are almost always associated with IgG or IgM. This is especially true during cold and flu season. How I manage patients suspected of having had an IgA anaphylactic transfusion reaction. Titers of anti-IgA did not distinguish these seemingly healthy blood donors from patients with a history of an anaphylactic transfusion reaction. The present report describes such a patient. Mandatory: Patients who have IgA deficiency and are destined for blood transfusion or IgG replacement therapy. Anaphylactic reaction with prothrombin complex concentrate in a patient with IgA deficiency and anti-IgA antibodies. Basic, Clinical - Hematologic, Organ-Based and Clinical Sciences . 7 Healthy volunteer blood donors or patients with immunodeficiency who are found to have IgA deficiency do not require IgA-deficient products for transfusion. 9. 0. No specific caution or testing is needed if a patient hasn’t been transfused before and they should be treated as someone without IgA deficiency for a first transfusion or if they have been transfused without problem. 1994 paper showing flaws in the link, with vast majority of severe allergic reactions not associated with IgA deficiency and 1/1200 donors showing IgA deficiency with anti-IgA: Sandler SG et al. 19 Lilic D, Sewell WAC. recurrent sinopulmonary infections; diarrhea from Giardiasis ; fatal anaphylaxis ; A 3-year-old girl is brought to the pediatrician by her father for fever. Anti‐IgA antibodies were found in 3 (25.0%) of 12 IgA‐deficient blood donors whose IgA levels were less than 5 mg/dl, a prevalence rate comparable to that in donors of European ancestry.
