Topical Tofacitinib as Effective Therapy in Patients with Plaque Psoriasis Responsive to Systemic Drugs but with Resistant Nail Psoriasis

Abstract

Introduction: Psoriasis is a chronic inflammatory disease that may also involve nails. Unfortunately, topical treatments available are limited and often responsible for side effects and/or lack of compliance due to the necessary prolonged use to see results. Intralesional treatment instead is often unwanted or unaccepted by patients. Lack of efficacy is, moreover, always a possible outcome. Novel modalities for the therapy of nail psoriasis are thus needed and always welcomed. Case Presentation: We then aimed to develop a topical 2% tofacitinib formulation expected to facilitate nail penetration and use in patients with recalcitrant forms of nail psoriasis unwilling to accept other routes of administration of treatment besides the topical one. Conclusion: These preliminary data, despite the use in 3 patients only, suggest a potential use of topical tofacitinib 2% for nail psoriasis. Further studies on bigger groups are however necessary to confirm the present encouraging results and establish the effectiveness and safety also in more severe cases or in the pediatric population.
