About this video
What do AD, CSU, PN, and BP have in common beneath the surface? Lawrence F. Eichenfield, MD, walks through four conditions that look nothing alike, clinically or histologically, yet share a contribution from type 2 inflammation. From the barrier, microbiome, and itch changes of atopic dermatitis to the largely edematous histology of a wheal, the nodules of prurigo nodularis, and blistering disease in older adults, he explores how one inflammatory pathway can produce such different diseases, and what that shared biology means for how clinicians approach treatment.
