302: Prurigo Nodularis 101: Triggers, Bo...

Many people have NOT heard about prurigo nodularis, but I feel like we will hear about it more and more in the coming years. It's incredibly ITCHY, and so many people have suffered from it because it's so relatively new in regards to being diagnosed. Prurigo nodularis nodules tends to be in middle-aged people, and it occurs in people who have not had skin issues their whole life! That's why I brought on the Super Man of "itch", and he does a deep dive in prurigo nodularis and how you can treat it.

My guest today is Shawn Kwatra, MD is a Director of the Johns Hopkins Itch Center and an Associate Professor of Dermatology at the Johns Hopkins University School of Medicine in Baltimore, MD, USA. He specializes in medical dermatology areas of clinical expertise include atopic dermatitis, psoriasis, chronic itch of unknown origin and dermatology for ethnic skin. Dr. Kwatra also runs a basic science laboratory and clinical trials unit and is funded by the National Institutes of Health and multiple foundations. Dr. Kwatra has been an author or co-author on over 200 publications and author of the book Living with Itch.

Quotes

"Prurigo nodularis is arguably the itchiest of itch disorders. And so that leads to this impaired sleep. Then that can just wreck your whole life." [14:00]

"In prurigo nodularis, you don't necessarily have that impaired barrier, but you have this stimulus of intense itch and skin thickening that then leads to secondary colonization (of bacterial infections)." [7:39]
