AbstractMajor allergic disease can be viewed as clinical syndromes rather than discrete disease entities. Emerging evidence indicates that allergic asthma includes several disease phenotypes. Immunological deviation toward high T helper cell type 2 cytokine levels has been demonstrated for a subgroup of pediatric asthma patients, and now, several novel monoclonal antibodies have been approved for treatment of this subgroup as a stratified approach of "personalized" medicine in allergy. Introduction of component-based IgE testing before allergen immunotherapy (AIT), i.e., testing for IgE cross-reactivity before initiation of AIT, has also brought stratified medicine into allergy therapy. Improved responder criteria, which identify treatment-responders previous to therapy, might foster this stratification and even individualized AIT might have an impact for tailor-made therapy in the future. Furthermore, combining antibody-based treatment with AIT could help to establish more rapid AIT protocols even for allergens with a high risk of anaphylactic reactions. Efforts to advance such "personalized" medicine in pediatric allergy might be challenged by several issues including high costs for the health-care system, increasing complexity of allergy therapy, the need for physician allergy expertise, and furthermore ethical considerations and data safety issues.
