Abrocitinib as a Novel Treatment for Multiple Skin Disorders: 3 Case Reports and a Scoping Review

Abstract

Janus kinase (JAK) inhibitors are increasingly being used in dermatology due to their broad potential in managing both local and systemic inflammation. More recently, abrocitinib, an oral JAK 1 inhibitor, has shown promising clinical efficacy in the treatment of various skin disorders beyond moderate to severe atopic dermatitis (AD). We firstly presented three cases, each with diagnosis of pyoderma gangrenosum (PG), livedoid vasculopathy (LV), or hidradenitis suppurativa (HS), and conducted a comprehensive scoping review of the available literature on the use of abrocitinib in the treatment of diverse skin disorders. We summarized a total of 16 skin disorders, including our cases. The results indicated that abrocitinib, whether used as monotherapy or in combination with other treatments, was effective and well-tolerated in these disorders. These findings expanded the range of diseases for which abrocitinib may serve as an alternative therapeutic choice.
