(Submitter supplied) Objective. Previous observations suggest that active systemic juvenile idiopathic arthritis (sJIA) is associated with a prominent erythropoiesis gene expression signature. The aim of this study was to determine the association of this signature with peripheral blood mononuclear cell (PBMC) subpopulations and its specificity for sJIA as compared to related conditions. 125 patients with JIA (18 sJIA and 107 non-sJIA) and 29 controls were studied. more...

(Submitter supplied) Systemic juvenile idiopathic arthritis (SJIA) is a chronic childhood arthropathy with features of autoinflammation. Early inflammatory SJIA is associated with expansion and activation of neutrophils with a sepsis-like phenotype, but neutrophil phenotypes present in longstanding and clinically inactive disease (CID) are unknown. The objective of this study was to examine activated neutrophil subsets, S100 alarmin release, and gene expression signatures in children with a spectrum of SJIA disease activity. more...

(Submitter supplied) Objective: A multi-center study of recent onset juvenile idiopathic arthritis (JIA) subjects prior to treatment with DMARDS or biologics was undertaken to identify peripheral blood gene expression differences between JIA subclasses and controls. Methods: PBMC from 59 healthy children and 136 JIA subjects (28 enthesitis-related arthritis[ERA], 42 persistent oligoarthritis, 45 RF- polyarthritis, and 21 systemic) were isolated on Ficoll. more...

(Submitter supplied) Systemic juvenile idiopathic arthritis (SJIA) confers high risk for macrophage activation syndrome (MAS), a life-threatening episode of hyperinflammation driven by IFN-γ. Monocytes in SJIA display IFN-γhyperresponsiveness, but the molecular basis of this remains unclear. The objective of this study is to identify monocyte and macrophage polarization phenotypes including features of interferon response. more...

(Submitter supplied) Objective. Follistatin-like protein 1 (FSTL-1) is a secreted glycoprotein that is over-expressed in certain inflammatory diseases. Our objective in this study was to correlate FSTL-1 levels with measures of clinical disease activity in systemic juvenile idiopathic arthritis (sJIA), including macrophage activation syndrome (MAS). Methods. FSTL-1 serum levels were measured by ELISA in 28 patients with sJIA, including 7 patients who developed MAS, as well as in 30 normal controls. more...

(Submitter supplied) We hypothesised that neutrophil pathways could be also be important in the pathogenesis of sJIA. We therefore studied the gene profile in both PBMC and neutrophils of sJIA patients treated with tocilizumab. We demonstrate that neutrophils from sJIA patients showed significantly different changes in gene expression in response to tocilizumab.

(Submitter supplied) Systemic Juvenile Idiopathic Arthritis (sJIA) has been strongly associated with macrophage activation syndrome (MAS). To better understand the pathogenesid of sJIA and to facilitate the search for MAS biomarkers, we examine gene expression profiles in untreated new onset sJIA. 17 new onset sJIA patients were included in the study. 5 of the 17 patients showed evidence of subclinical MAS and 2 eventually developed overt MAS. more...

(Submitter supplied) Objective. Microarray analysis was used to determine whether children with recent onset polyarticular juvenile idiopathic arthritis (JIA) exhibit biologically or clinically informative gene expression signatures in peripheral blood mononuclear cells (PBMC). Methods. Peripheral blood samples were obtained from 59 healthy children and 61 children with polyarticular JIA prior to treatment with second-line medications, such as methotrexate or biological agents. more...

(Submitter supplied) Systemic-onset juvenile idiopathic arthritis (soJIA) is a rheumatic disease in childhood characterized by systemic symptoms and a relatively poor prognosis. The peripheral leukocytes are thought to play the pathological role of soJIA although the exact cause is still obscure. In this study, we aimed to clarify the cellular functional abnormality in those cells. Here, we analyzed the gene expression profile in peripheral leukocytes from 51 patients with soJIA, 6 patients with poly-articular type JIA (polyJIA) and 8 healthy children utilizing DNA microarrays. more...

(Submitter supplied) Canakinumab is a human anti-interleukin-1 beta (IL-1 beta) monoclonal antibody neutralizing IL-1 beta. Systemic juvenile idiopathic arthritis (SJIA) is a rare, multigenic, autoinflammatory disease of unknown etiology characterized by chronic arthritis; intermittent high-spiking fever, rash, and elevated levels of acute-phase reactants. Blood samples of SJIA patients were obtained from two phase 3 clinical trials conducted by the members of the Pediatric Rheumatology International Trials Organization (PRINTO) and the Pediatric Rheumatology Collaborative Study Group (PRCSG) (Clinicaltrials.gov: NCT00886769 and NCT00889863). more...

(Submitter supplied) Human CD71+ erythroid cells (CECs) have been recognized to have an immunoregulatory function via direct cell-cell interaction and soluble mediators such as arginase-2 and reactive oxygen species. Circulating CECs increase in healthy newborns or patients with hemolytic, malignant and cardiopulmonary disorders. To assess the pathophysiological role of CECs in inflammatory diseases, we studied the gene expression and function focusing on systemic-onset juvenile idiopathic arthritis (SoJIA). more...

(Submitter supplied) The hypothesis tested in this study was that chronic exposure of PBMCs to a hypertensive environment in remodeled pulmonary vessels would be reflected by specific transcriptional changes in these cells. The transcript profiles of PBMCs from 30 idiopathic pulmonary arterial hypertension patients (IPAH), 19 patients with systemic sclerosis without pulmonary hypertension (SSc), 42 scleroderma-associated PAH patients (SSc-PAH), and 8 patients with SSc complicated by interstitial lung disease and PH (SSC-PH-ILD) were compared to the gene expression profiles of PBMCs from 41 healthy individuals.
