Neurological complications of biologic therapy in psoriasis: a review.
Biologic agents have been a significant advancement in the management of psoriasis. Along with significant clinical improvement, there have been concerns for emerging side effects with the use of biologics. Reports have emerged showing the association between efalizumab and the development of progressive multifocal leukoencephalopathy and other demyelinating disorders. Tumor necrosis factor-alpha inhibitors have been associated with various demyelinating disorders. As such, it is imperative for dermatologists to be well informed regarding how to notify patients about the risks of biologic treatment. Dermatologists must be able to identify the signs and symptoms of neurological complications and recognize when to refer patients to neurologists for diagnostic workup, disease confirmation, and any necessary treatment. This review is a compilation of evidence showing the association between biologic therapy and neurological complications, as well as an overview of the clinical presentation and diagnosis of such diseases.
