: Often the first sign in infancy, caused by skin barrier defects (e.g., filaggrin mutations) that allow for epicutaneous allergen sensitization.

While there is currently no cure, management focuses on controlling inflammation and restoring barrier function. Atopy - StatPearls - NCBI Bookshelf - NIH : Often the first sign in infancy, caused

Atopy typically follows a predictable chronological progression: Clinically, it manifests as a triad of conditions—,

Atopy is a genetic predisposition toward developing exaggerated IgE-mediated immune responses to common environmental allergens. Clinically, it manifests as a triad of conditions—, allergic rhinitis (hay fever) , and allergic asthma —often appearing sequentially in a pattern known as the "atopic march". 1. Pathophysiology and Mechanism : These cells produce cytokines (IL-4, IL-13) that

: Sensitization through inflamed skin can lead to early-onset food allergies.

: These cells produce cytokines (IL-4, IL-13) that trigger B cells to differentiate into plasma cells producing allergen-specific IgE.
