Biologic therapy is a treatment that strives to modulate a patient s immune system to fight a given disease. In psoriasis, a skin disorder that is partly caused by a dysregulated immune system resulting in well-demarcated red areas of the skin with white scales, biologic therapy has the potential to vastly improve upon patient outcomes by minimizing the symptoms of this disease while maximizing the safety profile of the therapy.           This book offers an up-to-date and comprehensive review on biologic therapy for the treatment of psoriasis. With over 10 FDA approved biologic agents for psoriasis (with more in the pipeline), confusion exists among providers regarding which agent is best for a particular patient. Chapters cover all FDA approved psoriasis biologic agents (including pipeline agents) for use in pediatric, adult, and geriatric patients.
