Vagus Nerve Stimulation

Abstract

Treatments for psoriasis and psoriatic arthritis have progressed at a rapid rate over the past 20 years, but treating patients with recalcitrant disease still remains a difficult task. Current therapies for these diseases involve topical agents, phototherapy, and systemic immunosuppression. However, the role of the nervous system in psoriasis and psoriatic arthritis remains largely unexplored. Recent animal studies and clinical trials have demonstrated that vagus nerve stimulation can decrease inflammatory processes in rheumatoid arthritis and inflammatory bowel disease. In this article, we outline the existing knowledge of the nervous system’s role in chronic inflammatory disease and discuss how these findings could be utilized in the future for treatment of psoriasis and psoriatic arthritis.
