How many phenotypes of asthma that clinicians can recognise?
• Late onset non-atopic asthma
• Early onset childhood atopic asthma
• Aspirin-induced asthma: Samter’s triad
• Corticosteroid-sensitive asthma associated with eosinophilia
• Asthma associated with chronic airflow obstruction
• Asthma with frequent exacerbations

Why do we need a systems medicine approach in severe asthma?
• A complex common disease with difficult definition
• Gene-environment interactions
• Variable disease with chronic changes
• Heterogeneous presentation
• Variable response to drugs
• Severe asthma, less responsive to current medications, need for new medications

Characteristics of severe asthma clinical traits
Early onset/childhood asthma vs late onset
Chronic airflow obstruction vs normal lung function
(Increased decline in FEV1)
Recurrent exacerbations vs occasional exacerbations
Atopic/high IgE vs non-atopic
Eosinophilic vs non-eosinophilic
Obese vs non-obese
Steroid-insensitive vs steroid-sensitive

Th2-high vs Th2-low in mild-moderate asthma
A: Mild-moderateasthmaB: Healthy
Features of Th2-high asthma● More blood and BAL eosinophils● ↑ serum IgE● ↑ mucin MUC5AC● ↑ IL5 and IL13 in biopsies● ↑ bronchial hyperresponsiveness● FEV1 increase with ICS
