[Asthma phenotypes and phenotyp-specific treatment]

Abstract

Asthma is not a homogenous disease but a bundle of different phenotypes producing common symptoms due to swelling of bronchial mucosa and constriction of the airway smooth muscle. Beyond the treatment with a combination of topical steroids and long-acting beta agonists, new therapeutic options arise with the knowledge of different phenotypes. One option, specifically in allergic asthma, is the long known allergen immunotherapy. To identify the individual phenotype a diagnostic work up is warranted when the asthma is diagnosed and whenever asthma control cannot be maintained.
