oligoarticular juvenile idiopathic arthritis

Ann Rheum Dis 1990;49(11):916–920. Which type your child has depends on symptoms, the number of joints affected, and if a fever and rashes are prominent features. Oligoarticular JIA affects 4 or fewer joints during the first 6 months of the disease. Weight-bearing joints and the jaw can also be affected. We observed a reduced ability of synovial monocytes to phagocytose and to perform oxidative burst by reactive oxygen species (ROS) production in response to PMA. is a broad term for childhood rheumatic diseases that begin before the age of 16 and are characterized by joint inflammation that lasts more than 6 weeks. Wang F, Flanagan J, Su N, Wang LC, Bui S, Nielson A, et al. Laboratory and radiographic testing provide classification and prognostic . Found inside – Page iThis volume provides a comprehensive and world-class review of the field of histiocytic neoplasms and hemophagocytic lymphohistiocytosis (HLH). Polyarticular juvenile idiopathic arthritis typically causes inflammation in five or more small joints (fingers and hands). PubMed Central  As a result, we observed a clear upregulation of specific markers in different phenotypes following polarization. We could not detect any de novo production of IL-6, IL-8, or IL-10 from monocytes stimulated with synovial fluid, even if these cytokines were found in the synovial fluid [23]. No laboratory studies are diagnostic but inflammatory markers are commonly elevated. Further research should be conducted regarding the functional role of these cells within the joint as recent studies have suggested a protective role of tissue-resident synovial monocytes/macrophages [34]. There was no significant difference in the expression of the M2 marker CD163 (235 vs 268). Lancet. c Synovial monocytes display an impaired phagocytosis compared to circulating monocytes: 1082 (846–1702) vs 1462 (1237–2353), **p < 0.01, n = 9. PubMed  Smiljanovic B, Radzikowska A, Kuca-Warnawin E, Kurowska W, Grun JR, Stuhlmuller B, et al. The clones and fluorophores are found in supplementary material. Macrophages expressing the scavenger receptor CD163: a link between immune alterations of the gut and synovial inflammation in spondyloarthropathy. Total RNA was extracted from monocytes isolated from synovial fluid and circulating monocytes by the RNeasy Mini Kit (Qiagen). Gaur P, Myles A, Misra R, Aggarwal A. *Unpaired SF samples. LPS (1 ng/ml) was used as positive control. J Rheumatol. Mantovani A, Sica A, Sozzani S, Allavena P, Vecchi A, Locati M. The chemokine system in diverse forms of macrophage activation and polarization. Psoriatic juvenile idiopathic arthritis is a subtype of juvenile idiopathic arthritis that is characterized by both arthritis and psoriasis.Other signs and symptoms may include dactylitis (inflammation and swelling of an entire finger or toe); nail pitting or splitting; and eye problems. Arthritis Rheum. Gating on percentage positive cells, barely 37% (median) of the synovial fluid monocytes expressed CD206, even though the MFI values were markedly increased. Google Scholar. Additionally, a general expression of TNF and IL-10 mRNA in macrophage rich areas in synovial biopsies, as well as single and co-expression of CD40 and CD206 in monocytes/macrophages supports the idea that the macrophages/monocytes are polarized, suggesting that M1 (and M2) features can be obtained in the synovial membrane, and not exclusively in the synovial fluid. Juvenile idiopathic arthritis (JIA), is the most common, chronic rheumatic disease of childhood, affecting approximately one per 1,000 children. 2014;9(10):e109775. Oligoarticular JIA affects 4 or fewer joints during the first 6 months of the disease. Slipped capital femoral epiphysis. Diagnosis is made clinically. Multiple cytokines and chemokines have previously been shown to be elevated at the protein level in patients with oligoarticular JIA, e.g., CXCL10, IL-6, and IL-8 [23]. Found insideThis handbook is an in-depth and comprehensive guide for the treatment and management of patients with juvenile idiopathic arthritis. Which type your child has depends on symptoms, the number of joints affected, and if a fever and rashes are prominent features. 2019;9(1):1925. We therefore hypothesized that the monocytes might attain, at least partly, their polarization pattern when migrating through the synovial tissue. CAS  Details on sample handling are found in supplementary material. Methods: CLIPPER is an ongoing, Phase 3b, open-label, multicentre study; the 12-week (Part 1) data are reported here. Treatment involves intra-articular corticosteroids and disease-modifying antirheumatic drugs. Giancane G, Consolaro A, Lanni S, Davi S, Schiappapietra B, Ravelli A. 4). For example, IL-10 positive M2(IL-10)-like macrophages have been found in the lining layer of the synovium in rheumatoid arthritis (RA) and, more prominently, in spondylarthritis (SpA), whilst the sub-lining layers consisted more of a heterogenous M1/M2-like pattern [14]. This compact text is designed for easy use in the examination room, laboratory, or consultation office. Synovial fluid monocytes showed a reduced ability to phagocytose as compared to paired circulating monocytes (MFI; 1082 vs 1462, p < 0.01), Fig. California Privacy Statement, Despite this, little is known about neutrophil function at the site of inflammation in JIA and how local neutrophils contribute to disease pathogenesis. Stimulation of phagocytosis was performed using opsonized E. coli and ROS production using PMA. PubMed  Some forms can cause eye inflammation. Treatment focuses on controlling pain and inflammation, improving function, and preventing damage. Find fast answers to inform your daily diagnosis and treatment decisions! Ferri’s Clinical Advisor 2021 uses the popular "5 books in 1" format to deliver vast amounts of information in a clinically relevant, user-friendly manner. Ann Rheum Dis. Oligoarticular JIA affects about 40 to 60% of those with JIA and is more common in females than males (5:1) with average age of onset rheumatoid arthritis. ) Found inside – Page iiThis book, the first complete textbook on this novel field in Medicine, comprehensively covers the clinical presentation, pathogenesis, genetics, and latest management strategies for autoinflammatory disorders as well as the basic science ... Conversely, unpolarized and M2-polarized cells displayed an unaltered or increased phagocytosis [10, 33]. Chronic Uveitis is defined as a persistent uveitis characterized with prompt relapse in less than 3 months after . Etanercept treatment for extended oligoarticular juvenile idiopathic arthritis, enthesitis-related arthritis, or psoriatic arthritis: 6-year efficacy and safety data from an open-label trial Arthritis Res Ther.

Found inside – Page iiiThis book discusses the role of the microbiome in rheumatic diseases and details its implications for patient treatment. Recently, with technological advances, there has been significant research into the microbiome. Oligoarticular juvenile idiopathic arthritis (JIA) is defined as a chronic inflammatory arthritis of unknown origin that begins before the age of 16 and persists for at least 6 weeks ( Box 18-1 ).It is further characterized as being either persistent (if no more than four joints are affected during the disease course) or extended (if, after the initial 6-month period, the total . This means it will probably last a long time. Each subtype has distinct clinical, immunologic and genetic features. https . Arthritis Care and Research.

Patients may also develop chronic eye inflammation. Arthritis Res Ther 22, 186 (2020). Staining for polarization markers revealed both single and co-expression of CD40 and CD206 in macrophages, as well as in other cell types as neither CD40 nor CD206 is specific for monocytes/macrophages. Google Scholar. 2019; https://www.mdedge.com/familymedicine/article/196058/rheumatology/juvenile-idiopathic-arthritis-old-disease-new-tactics. SF n = 13, plasma n = 9. There are several subtypes, including oligoarticular, polyarticular, and systemic onset. Finally, M2(IL-10) are highly phagocytic and efferocytic, expressing CD163, as well as CD16 and HO-1 [12]. Incubated blood was lysed (TQ-prep with Immunoprep reagent system, Beckman Coulter). Diagnosis is made clinically. MFI-median fluorescence intensity. Download PDF. Stansfield BK, Ingram DA. For detailed information see supplementary material. Arthritis Rheum. 2b, c) as well as being less prone to undergo oxidative burst upon stimulation with PMA (MFI; 234 vs 337, p < 0.01, Fig. Circulating and synovial intermediate CD14+CD16+ monocytes are expanded in enthesitis-related JIA, where synovial monocytes display a M2(IL-10)-like pattern [16, 17]. Patient data and characteristics are summarized in Table 1. A short summary of this paper. CD14+,CD16+ blood monocytes and joint inflammation in rheumatoid arthritis. Synovial fluid did not induce production of IL-6, IL-8, IL-10 or TNF in healthy monocytes as compared to plasma from healthy donors. Phagocytosis and ROS production was assessed by PhagoTest™ and PhagoBurst™ (BD Biosciences), respectively, according to the manufacturer’s instructions. Cells were cultured in RPMI 1640 medium supplemented with 2.05 mM l-glutamine (Gibco Life Technologies) and 10% normal human serum (Sigma-Aldrich) overnight at 37 °C, 5% CO2. Unpaired data was analyzed based on the geometric mean of the patients with paired circulating monocytes. If this condition is left untreated, it may result in cataracts, glaucoma and even blindness. Juvenile arthritis (JA), the name given to arthritis diagnosed in children through age 16, is thought to affect about 1 in 500 children. The synovial fluid monocytes were functionally affected as shown by reduced phagocytosis and oxidative burst. P < 0.05 was considered statistically significant. It typically is also the disease’s mildest form, one that affects four or fewer joints within the first six months of diagnosis, and is usually marked by joint pain and swelling. Paired samples were analyzed by the Wilcoxon’s matched-pairs signed-rank test. The macrophages have been shown to produce different levels of pro- and anti-inflammatory mediators in different diseases, and their number correlates to disease activity in RA [14, 30, 31]. Antibodies to CD14 and CD68 were also tested and provided similar staining, but CD163 provided the most specific staining. In addition, the children displayed a distinct homology in their monocyte pattern regardless of disease duration, suggesting common pathophysiological mechanisms of arthritis in this patient group. Monocytes simultaneously showing M1- and M2-like properties are identified in vivo, seemingly highly context-dependent. In parallel, monocytes were isolated from blood (n = 5) and synovial fluid (n = 9) for RNA extraction. The synovial membrane contained dense populations of lining- and sub-lining macrophages, with a mixed expression of IL-10, TNF, CD40, and CD206.
