[Type-2 Asthma: Leaving Behind the Perspective of the Seventies].

Type-2 Asthma: Leaving Behind the Perspective of the Seventies Abstract. The diagnosis 'bronchial asthma' spans different phenotypes of this disease like an umbrella. The differentiation of these phenotypes and their overlaps is becoming increasingly important, as the phenotype-specific treatment approaches of today are not effective with every form of asthma. These approaches include the strategy of allergen avoidance, allergen immunotherapy and, most importantly, the newly available biologics for asthma. Treatable disease patterns, so-called 'treatable traits', require targeted diagnostics. The knowledge necessary to identify these traits still needs to be established in practice.
