The latest instalment of the ERS Interactive Education video series is now available to watch on the ERS Respiratory Channel. 

‘IL-5 in severe asthma: halting progression, achieving remission’ aims to bridge gaps in knowledge by linking IL-5 biology to clinical outcomes through case-based learning led by experts in the field. 

Severe eosinophilic asthma, driven by IL-5-mediated eosinophilic inflammation, airway remodelling, and mucus plugging, remains a clinical challenge due to persistent gaps in diagnosis and management. Clinicians often struggle to differentiate adult-onset asthma from COPD, underutilise biomarkers, and delay IL-5 biologics despite their proven efficacy in reducing exacerbations and halting progression. Overreliance on steroids and misconceptions about remission – prioritising symptom control over structural stability – further hinder care. 

The experts – Dr Hitasha Rupani, Prof. Marek Lommatzsch and Prof. Arnaud Bourdin – will lead participants through this topic to enable them to: 

  1. Explain how IL-5-driven eosinophilic inflammation contributes to airway remodeling, mucus plugging, and functional decline in severe asthma. 
  2. Differentiate adult-onset eosinophilic asthma from COPD using clinical history, biomarkers, and imaging. 
  3. Evaluate the role of IL-5-targeted biologics in halting disease progression by reducing exacerbations and preserving lung function. 
  4. Apply strategies to achieve remission through biomarker-guided therapy and steroid-sparing approaches.
