Introduction The nuclear oncoprotein DEK is a biochemically distinct, pro-inflammatory protein that is a chemoattractant for neutrophils and T-cells. High levels of DEK autoantibodies have been found in several autoimmune diseases including juvenile idiopathic arthritis (JIA), but their role in disease pathogenesis is unclear.
Objectives Since DEK and DEK autoantibodies can contribute to the development of immune complexes and joint inflammation, we suggest that DEK antibody levels can predict disease flare with discontinuation of anti-TNF therapy. Methods In 16 pediatric rheumatology centers, sera samples were collected from 137 children with polyarticular JIA on anti-TNF therapy. Therapy was stopped after 6 …
