A Review for Physician Assistants and Nurse Practitioners on the Considerations for Diagnosing and Treating Psoriatic Arthritis

Abstract

Psoriatic arthritis (PsA) is a clinically heterogeneous form of progressive inflammatory arthritis that affects up to 30% of patients with psoriasis. The rapid rate of progression associated with PsA makes early-disease diagnosis and treatment crucial to patients' quality of life and long-term health. With the aim of providing clinical guidance to physician assistants and nurse practitioners, this article gives an overview of the different PsA clinical domains, including peripheral arthritis, axial disease, enthesitis, dactylitis, skin disease, and nail dystrophy, which should be considered as part of diagnosis and treatment strategies. The efficacy of different therapies across these PsA domains is reviewed within the context of current PsA treatment guidelines while considering more recent data on newly approved therapies for PsA.
