[Anti-cytokine treatment, newly developed].

Rheumatoid arthritis (RA) is characterized by chronic inflammatory synovitis that causes pain, loss of function and disability, and can significantly reduce health-related quality of life. Improved understanding of the pathogenesis has led to the development of new biologic treatments that target specific cytokines. Large randomized controlled trials (RCTs) have been conducted to show the efficacy of anti-TNF and IL-6. However, despite these treatments, some patients fail to respond to these therapies. Recently other anti-ctyokine treatments had been developed and introduced. Here, we discuss about new anti-cytokine treatments for RA.
