“You have to stop treating psoriasis as just a skin disease”.

In Switzerland, psoriasis affects about 1 to 3 percent of the population [1]. About one in three psoriasis patients also suffers from psoriatic arthritis (PsA), a chronic inflammatory systemic disease that can manifest itself in arthritis, enthesitis, and dactylitis, among other things [2, 3]. If left untreated, PsA can result in joint destruction and even disability [2]. In the following interview, dermatologist Prof. Thomas Kündig and rheumatologist Prof. Diego Kyburz discuss the interdisciplinary management of this complex disease and elaborate on two current therapeutic options [4, 5].
