This disease often remains severe and debilitating. The purpose of this study was to compare gene expression profiles in peripheral blood mononuclear cells (PBMCs) from patients with active and inactive systemic JIA to define and better understand the cause of active disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Gene expression profiles of PBMCs were determined in cells from 9 patients with active systemic JIA and 8 patients with inactive systemic JIA. Unsupervised clustering and significance analysis were performed. We compared the systemic JIA profile with data from patients with polyarticular JIA, chronic infantile neurologic, cutaneous, articular syndrome, Kawasaki disease, and systemic lupus erythematosus to identify disease\u2010specific genes. Quantitative reverse transcription\u2013polymerase chain reaction of selected genes was performed on negatively selected B cells, T cells, and monocytes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Unsupervised clustering of expressed genes resulted in 2 groups that corresponded to the clinical status of the patients (active and inactive disease) and was independent of their medications. A total of 286 genes were identified as significantly up\u2010regulated in patients with active disease and 86% of them were specific to systemic JIA. Interleukin\u20106 (IL\u20106) was expressed in monocytes and B cells, IL\u201010 in monocytes, and suppressor of cytokine signaling 3 in monocytes and T cells from patients with active disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Gene expression profiles in PBMCs identified disease\u2010specific genes in patients with systemic JIA.
