The use of ustekinumab in autoimmune disease.

IMPORTANCE OF THE FIELD

The advent of biologic therapies has revolutionized the treatment of autoimmune diseases including psoriasis, autoimmune arthritides and inflammatory bowel disease. With recent advances in our understanding of the immunogenetic pathways involved in the pathogenesis of these conditions, newer, more targeted biologic therapies have been developed. Ustekinumab is an antibody to the common p40 subunit of IL-12 and IL-23, which has been studied in the treatment of psoriasis, psoriatic arthritis, Crohn's disease and multiple sclerosis.
