MOA?
50% of pts with eczema develop ASTHMA.
50-75% develop ALLERGIC RHINITIS.
MOA: Atopy!
What is the atopic march?
- Atopy: personal and/or familial propensity to produce IgE Abs and sensitization in response to environmental triggers
- Describes progression of atopic disorders from atopic derm in infants to AR and RAD in children
TQ
What is the MOA of the atopic march?
Early barrier dysfunction (atopic dermatitis – itch before rash!) ››
Epicutaneous sensitization ››
Th2 response with increased IgE and increased IL-13 ››
Asthma, atopy
- Inflammatory condition of nasal mucosal membranes
- Allergens provoke allergic response in sensitized individuals
- 80% with have asthma
- Even without asthma, pts have increased lower airway reactivity
- Can precede asthma in allergic march or be an endpoint
