IL-1 receptor antagonist (IL-1Ra) competitively inhibits the interaction of IL-1 with its receptors.
Is Anakinra approved for DMARDs?
Anakinra is approved for the treatment of rheumatoid arthritis refractory to conventional DMARDs, but it has relatively modest efficacy. Anakinra, canakinumab, and rilonacept exert marked anti-inflammatory effects in hereditary systemic autoinflammatory diseases (Chapter 269) characterized by enhanced IL-1β production, leading to their approval for this indication. Anakinra is effective in some patients with systemic inflammatory diseases, including systemic-onset juvenile idiopathic arthritis, adult-onset Still's disease, and other autoinflammatory conditions. Clinical trials have reported encouraging results in crystal-induced arthritis such as gout and chondrocalcinosis. Promising results have also been reported from the use of anakinra in type 2 diabetes mellitus and smoldering/indolent multiple myeloma.

Abstract
Kawasaki disease (KD) is a form of self-limiting vasculitis that causes coronary artery abnormalities in children. Although clinical trials of monoclonal antibodies and anti-cytokine biologics that block cytokine cascades have been conducted, the studies have revealed contradictory results.
Introduction
Kawasaki disease (KD) was originally described in 1967 by Tomisaku Kawasaki, and is of unknown etiology. KD mainly affects children less than 5 years of age, and is the major cause of acquired pediatric heart disease in developed countries [1].
Methods
We conducted this systematic review and meta-analysis according to the Cochrane Handbook for Systematic Reviews of Interventions and reported the systematic review process according to the flow diagram of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines ( Fig. 1) [16].
Results
We found 1486 studies by the preliminary search and one study by the manual search based on the registry data of on-going studies. By first screening, 1114 articles were excluded.
Discussion
This meta-analysis demonstrated that treatment resistance was reduced by TNF-α inhibitors, including infliximab and etanercept, compared with conventional IVIG therapy alone. This systematic review also provided some evidence regarding the rate of use of specific monoclonal antibody and anti-cytokine agents.
