[Allergen immunotherapy for atopic dermatitis].

Since the first report of allergen-specific immunotherapy (AIT) by Noon et al. 110 years ago, a multitude of clinical and in vitro studies have been performed to identify the effects of the only curative treatment for allergies. However, in atopic dermatitis (AD), one of the most prevalent skin diseases, it is rarely used, despite evidence showing that aeroallergens can contribute to disease exacerbation. This review gives an overview about the studies, meta-analyses, and current guideline recommendations regarding AIT in AD patients. There is a distinct heterogeneity in the study designs, different allergens and application forms, endpoints and patient cohorts, which hinders the comparability of studies. Several trials depict a beneficial effect of AIT in AD patients suggesting that at least a subgroup of patients can benefit from treatment. Further developments in the field of AIT may advocate broader use in AD patients.
