Total IgE Levels Better Predict Atopic Dermatitis Flares Than Disease Severity, and Both Are Reduced by Dupilumab Treatment.
BACKGROUND Elevated IgE levels are common in atopic dermatitis (AD). Although their role in AD pathogenesis is unclear, elevated IgE levels may be associated with disease exacerbation. OBJECTIVE To investigate the association of total IgE and/or disease severity with flares and dupilumab's impact on IgE levels and fl...
