Anti-IgE autoantibody in patients with atopic dermatitis. 1985

Y Nawata, and T Koike, and H Hosokawa, and H Tomioka, and S Yoshida

The anti-IgE autoantibody in the IgG class was detected in 39/45 (86.7%) patients with atopic dermatitis by using a newly established solid-phase enzyme immunoassay. The epsilon-chain specificity of the anti-IgE autoantibody was confirmed by competitive inhibition by using human IgG, IgA, IgM, IgD, IgE, and heat-denatured IgE protein. Significant correlations were observed between the levels of the anti-IgE autoantibody and the serum IgE. Gel filtration studies indicated that the anti-IgE autoantibody in sera from atopic dermatitis was mainly present in the form of an immune complex with self IgE. The role of the IgE-anti-IgE immune complex and the role of the anti-IgE autoantibody in the modulation of the IgE-mediated immune system in atopic dermatitis are discussed.

UI MeSH Term Description Entries
D007073 Immunoglobulin E An immunoglobulin associated with MAST CELLS. Overexpression has been associated with allergic hypersensitivity (HYPERSENSITIVITY, IMMEDIATE). IgE
D003876 Dermatitis, Atopic A chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. It is manifested by lichenification, excoriation, and crusting, mainly on the flexural surfaces of the elbow and knee. In infants it is known as infantile eczema.
