Update on the management of systemic juvenile idiopathic arthritis and role of IL-1 and IL-6 inhibition

摘要

Systemic juvenile idiopathic arthritis (SJIA) is a disease marked with arthritis and several features of systemic inflammation including fevers, rashes, hepatosplenomegaly, lymphadenopathy, and serositis. The presentation can be variable and arthritis can be a later feature. Macrophage activation syndrome can be a life-threatening complication of this illness and requires early recognition and prompt therapy. Advancements in understanding the biology of SJIA have led to the development of cytokine-targeted therapies, mainly interleukin-1 (IL-1) and IL-6 inhibitors that have significantly improved outcomes. In this review, we provide an update on the advances in the understanding of SJIA biology and also the therapeutic options.
