Severe eosinophilic asthma: a roadmap to consensus

Asthma is widely accepted as a complex heterogeneous condition with diverse pathophysiological mechanisms, clinical presentations, comorbidities, physiological characteristics, pathology and outcomes that is typically best managed by a multidisciplinary team [1–4]. Severe asthma is recognised as a major unmet need with a high personal and social impact, as well as a high burden on healthcare resources [4]. As a consequence of advances in the development of precision medicines for patients with severe asthma, the need to identify asthma subtypes by phenotype based on clinical, functional or inflammatory parameters is becoming a mandatory part of management [4–6].
