[Immunopathologic disorders in atopic dermatitis].
The atopic dermatitis is a multifactorial inheritable disease, in which pathogenesis in addition to environmental factors (climate, allergens, clothing) genetically determined multiplex metabolic differences (arachidonic acids, essential fatty acids) and immunologic alterations play an important role. Within immunologic findings the disturbances of balance in Th1 and Th2 subclasses, the increased degranulation activity of mast cells and the increased antigen presentation activity of Langerhans cells can be stressed. The clinical immunological alterations shown in the diseases, the increased production of IgE and so the type I. allergic reactions (urticaria, gastrointestinal manifestation of food allergy, allergic rhinitis, asthma bronchiale), the difference of cellular immunity of the skin can be explained by the above mentioned main immunological changes. In understanding of immunological origin of atopic dermatitis the IgE receptors expressed on the surface of Langerhans cells (connecting the immediate and delayed type of immune response) mean significant help.
