How is Atopic Dermatitis Severity Measured? Lesion Severity vs Inflammatory Burden Lesion Severity Measured through vIGA - AD Inflammatory Burden Measured through EASI ▪ Validated Investigator Global Assessment (vIGA - AD) : A 5 point scale (0 - 4) rating overall disease severity based on the worst lesion characteristics – erythema, papulation, and lichenification . ▪ Eczema Area Severity Index (EASI) : A weighted score (0 - 72) that accounts for the extent (% body surface area) and intensity of inflammation across 4 body regions. ▪ Key Difference : vIGA reflects the severity of the single worst area; EASI captures total inflammatory burden across the whole body. vIGA = 4 EASI ≈ 1.1 vIGA = 4 EASI ≈ 17 10
