Selective IgA deficiency in early life : Association to infections
There is no cure for IgA deficiency. Immunotherapy does not work to treat it. Complications for IgA deficiency include asthma, diarrhea, ear and eye infections, autoimmune diseases, and pneumonia. Det finns fem immunglobulinklasser: IgM, IgD, IgG, IgA och IgE. IgG och IgA delas dessutom in i undergrupper som kallas subklasser. IgG är viktigast för försvaret mot bakterier som kommit in i kroppen, medan IgA finns på kroppens slemhinnor för att hindra att bakterier tar sig in.

Immunotherapy does not work to treat it. Complications for IgA deficiency include asthma, diarrhea, ear and eye infections, autoimmune diseases, and pneumonia. IgA deficiency and atopic disease is common in the general population and there is some evidence that atopic disease is more common in IgA deficiency. This observation could be related to more infectious symptoms bringing the atopic disease to attention or to the lack of IgA competing with IgE for binding to inhaled or ingested allergens.

1. Selective IgA deficiency is defined as the isolated undetectable serum IgA (with normal IgG and IgM levels) in a patient older than 4 years of age. Immunoglobulin G (IgG): This is the most common antibody. It's in blood and other body fluids, and protects against bacterial and viral infections. IgG can take time Common variable immunodeficiency represents another antibody deficiency syndrome and is the most common after IgA deficiency.
It is also found in saliva, tears, and breastmilk. A deficiency seems to play a part in asthma and allergies. INTRODUCTION AND DEFINITION Selective immunoglobulin (Ig)E deficiency is defined as a significant decrease in the levels of IgE (<2.5 international units/mL) in a patient whose other immunoglobulin levels, including IgG, IgG subclasses, and IgA levels, are normal. Isolated IgE deficiency and combined IgE-IgA deficiency do not predispose individuals to recurrent respiratory tract disease. In contrast, IgA-deficient patients with normal or elevated levels of IgE frequently have recurrent respiratory infections. Although IgE deficiency and combined IgE-IgA deficiency occur frequently in ataxia-telangiectasia, IgA deficiency and atopic disease is common in the general population and there is some evidence that atopic disease is more common in IgA deficiency.
