DefinitionThis section has been translated automatically.
Genetic disposition to the development of atopy. Probably there is not the "atopic gene". Rather, it can be assumed that the "atopic genes" belong to the general repertoire of the human genome. Environmental and other factors lead to overexpression of these genes and manifestation of atopic manifestations. Thus, the atopic type is to be conceived as an "atopic phenotype" rather than an "atopic genotype". A central aetiopathogenetic significance in the triggered inflammatory cascade is attributed to the production of Th2 cytokines (in contrast to psoriasis).
In clinical practical use, the use of an atopy score is important in order to obtain firm indications of atopic eczema.
Occurrence/EpidemiologyThis section has been translated automatically.
The prevalence of atopic diseases is probably around 30%.
