Juvenile Idiopathic Arthritis-Associated Chronic Uveitis: Recent Therapeutic Approaches.

ABSTRACT: Pediatric patients with early onset (before the age of 6 years), antinuclear antibody positive, oligoarticular or polyarticular juvenile idiopathic arthritis (JIA), and some children with no arthritis may develop chronic, anterior uveitis. Recent recommendations insist on the need to perform slit lamp examination every 3 months for at least 5 years in early onset JIA patients in order to diagnose uveitis before complications develop. Local steroid therapy is usually the first-line treatment. However, in patients requiring steroid eye drops for several months, systemic immunomodulatory therapy is indicated. Methotrexate (MTX) is then prescribed in most cases; however, some patients also need anti-tumor necrosis factor alpha monoclonal antibody therapy and, in some cases, other biologics to control uveitis and avoid long-term ocular damage. Expert ophthalmologists and pediatricians must be involved in taking care of such patients. Immunomodulatory treatment must not be too easily interrupted and may even be intensified in some cases, particularly if there is a need for optimal disease control before ophthalmologic surgery. In good responders to MTX and/or biologics, treatment must be maintained at least 1 year, possibly even 2 years after achieving remission before tapering treatment intensity.

Juvenile idiopathic arthritis-associated uveitis.

Project description:Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease of childhood, with JIA-associated uveitis its most common extra-articular manifestation. JIA-associated uveitis is a potentially sight-threatening condition and thus carries a considerable risk of morbidity. The aetiology of the condition is autoimmune in nature with the predominant involvement of CD4(+) T cells. However, the underlying pathogenic mechanisms remain unclear, particularly regarding interplay between genetic and environmental factors. JIA-associated uveitis comes in several forms, but the most common presentation is of the chronic anterior uveitis type. This condition is usually asymptomatic and thus screening for JIA-associated uveitis in at-risk patients is paramount. Early detection and treatment aims to stop inflammation and prevent the development of complications leading to visual loss, which can occur due to both active disease and burden of disease treatment. Visually disabling complications of JIA-associated uveitis include cataracts, glaucoma, band keratopathy and macular oedema. There is a growing body of evidence for the early introduction of systemic immunosuppressive therapies in order to reduce topical and systemic glucocorticoid use. This includes more traditional treatments, such as methotrexate, as well as newer biological therapies. This review highlights the epidemiology of JIA-associated uveitis, the underlying pathogenesis and how affected patients may present. The current guidelines and criteria for screening, diagnosis and monitoring are discussed along with approaches to management.

Juvenile idiopathic arthritis-associated uveitis.

Project description:To describe recent evidence from the literature pertaining to juvenile idiopathic arthritis (JIA)-associated uveitis.Uveitis is most common in extended oligoarticular JIA. A significant number of patients already have ocular complications at time of diagnosis of uveitis. Risk factors for complications include either abnormally high or low intraocular pressure, posterior synechiae, male sex, temporal proximity to diagnosis of arthritis and topical corticosteroid use. Use of immunosuppressive agents significantly reduces ocular complications. Aggressive perioperative control of intraocular inflammation is necessary for successful cataract surgery with lens implantation. Controlled clinical trials are under way to assess the efficacy of biologic agents in JIA-associated uveitis. Long-term safety, however, is still unknown.JIA-associated uveitis carries significant ocular morbidity that lasts well into adulthood. Treatment with immunosuppressive agents can reduce the risk of ocular complications. Biologic agents hold promise in the treatment of JIA-associated uveitis, but require long-term data to assess their safety.

Juvenile Idiopathic Arthritis Associated Uveitis.

Project description:Juvenile idiopathic arthritis (JIA) is the most common childhood rheumatic disease. The development of associated uveitis represents a significant risk for serious complications, including permanent loss of vision. Initiation of early treatment is important for controlling JIA-uveitis, but the disease can appear asymptomatically, making frequent screening procedures necessary for patients at risk. As our understanding of pathogenic drivers is currently incomplete, it is difficult to assess which JIA patients are at risk of developing uveitis. Identification of specific risk factors for JIA-associated uveitis is an important field of research, and in this review, we highlight the genomic, transcriptomic, and proteomic factors identified as potential uveitis risk factors in JIA, and discuss therapeutic strategies.

Recent advances in the treatment of juvenile idiopathic arthritis-associated uveitis.

Project description:Juvenile idiopathic arthritis-associated uveitis has an estimated prevalence of 10-20% in patients with juvenile idiopathic arthritis, making it the most common cause of chronic anterior uveitis in children. Prompt treatment is important to prevent development of ocular complications and permanent vision loss. In this review, we will discuss the use of immunosuppression in treatment of juvenile idiopathic arthritis-associated uveitis. This will include the use of conventional immunosuppressants, such as methotrexate, biologic anti-tumor necrosis factor agents, such as adalimumab, as well as other anti-tumor necrosis factor agents, including infliximab and golimumab. In addition, we will discuss medications currently in clinical trials or under consideration for juvenile idiopathic arthritis-associated uveitis, including interleukin-6 inhibitors (tocilizumab) and Janus kinase inhibitors (tofacitinib, baricitinib).

Juvenile idiopathic arthritis: from aetiopathogenesis to therapeutic approaches.

Project description:Juvenile idiopathic arthritis (JIA) is the most common paediatric rheumatological disorder and is classified by subtype according to International League of Associations for Rheumatology criteria. Depending on the number of joints affected, presence of extra-articular manifestations, systemic symptoms, serology and genetic factors, JIA is divided into oligoarticular, polyarticular, systemic, psoriatic, enthesitis-related and undifferentiated arthritis. This review provides an overview of advances in understanding of JIA pathogenesis focusing on aetiology, histopathology, immunological changes associated with disease activity, and best treatment options. Greater understanding of JIA as a collective of complex inflammatory diseases is discussed within the context of therapeutic interventions, including traditional non-biologic and up-to-date biologic disease-modifying anti-rheumatic drugs. Whilst the advent of advanced therapeutics has improved clinical outcomes, a considerable number of patients remain unresponsive to treatment, emphasising the need for further understanding of disease progression and remission to support stratification of patients to treatment pathways.

Childhood Arthritis and Rheumatology Research Alliance Consensus Treatment Plans for Juvenile Idiopathic Arthritis-Associated and Idiopathic Chronic Anterior Uveitis.

Project description:OBJECTIVE:Systemic immunosuppressive treatment of pediatric chronic anterior uveitis (CAU), both juvenile idiopathic arthritis-associated and idiopathic anterior uveitis, varies, making it difficult to identify best treatments. The Childhood Arthritis and Rheumatology Research Alliance (CARRA) developed consensus treatment plans (CTPs) for CAU for the purpose of reducing practice variability and allowing future comparison of treatments using comparative effectiveness analysis techniques. METHODS:A core group of pediatric rheumatologists, ophthalmologists with uveitis expertise, and a lay advisor comprised the CARRA uveitis workgroup that performed a literature review on pharmacologic treatments, held teleconferences, and developed a case-based survey administered to the CARRA membership to delineate treatment practices. We held 3 face-to-face consensus meetings using nominal group technique to develop CTPs. RESULTS:The survey identified areas of treatment practice variability. We developed 2 CTPs for the treatment of CAU, case definitions, and monitoring parameters. The first CTP is directed at children who are naive to steroid-sparing medication, and the second at children initiating biologic therapy, with options for methotrexate, adalimumab, and infliximab. We defined a core data set and outcome measures, with data collection at 3 and 6 months after therapy initiation. The CARRA membership voted to accept the CTPs with a >95% approval (n = 233). CONCLUSION:Using consensus methodology, 2 standardized CTPs were developed for systemic immunosuppressive treatment of CAU. These CTPs are not meant as treatment guidelines, but are designed for further pragmatic research within the CARRA research network. Use of these CTPs in a prospective comparison effectiveness study should improve outcomes by identifying best practice options.

Genetic aspects of idiopathic paediatric uveitis and juvenile idiopathic arthritis associated uveitis in Chinese Han.

Project description:BackgroundIdiopathic paediatric uveitis (IPU) and juvenile idiopathic arthritis associated uveitis (JIA-U) are the two most common entities in paediatric uveitis. This study addressed the possible association of IPU and JIA-U with genes that had been shown earlier to be associated with juvenile idiopathic arthritis.MethodsWe carried out a case-control association study involving 286 IPU, 134 JIA-U patients and 743 healthy individuals. A total of 84 candidate single nucleotide polymorphisms (SNPs) in 60 genes were selected for this study. The MassARRAY platform and iPLEX Gold Genotyping Assay was used to genotype 83 candidate SNPs and the remaining SNP (rs27293) was analysed using the TaqMan SNP Genotyping Assay.ResultsNo evidence was found for an association of the candidate polymorphisms tested with IPU. Six SNPs (PRM1/rs11074967, JAZF1/rs73300638, IRF5/rs2004640, MEFV/rs224217, PSMA3/rs2348071 and PTPN2/rs7234029) showed an association with JIA-U (p<1.0×10-2).ConclusionOur findings showed associations of six SNPs (PRM1/rs11074967, JAZF1/rs73300638, IRF5/rs2004640, MEFV/rs224217, PSMA3/rs2348071 and PTPN2/rs7234029) with JIA-U. No association was detected between the 84 tested SNPs and IPU.

Identification of Ocular Autoantigens Associated With Juvenile Idiopathic Arthritis-Associated Uveitis.

Project description:The purpose of the current study was to analyze the binding patterns of serum autoantibodies from juvenile idiopathic arthritis (JIA) and JIA-associated uveitis (JIAU) patients to proteomes from different ocular tissues and to identify potential ocular autoantigens in JIAU. Proteomes from porcine iris, ciliary body, or retina tissue were isolated, separated using 2D-gel electrophoresis, and transferred to a blotting membrane. The binding pattern of serum antibodies from JIA or JIAU patients or healthy controls to ocular proteins was visualized by using anti-human IgG secondary antibodies and chemiluminescence reaction. Selected protein spots were excised from silver-stained 2D gels and subjected to mass spectrometry. Serum antibodies binding to ocular proteins were detected in all patient groups and healthy controls. Irrespective of the patient groups, serum antibodies bound to 49 different protein spots of the retina proteome, to 53 of the ciliary body proteome, and to 44 of the iris proteome. The relative binding frequency of sera to these iris protein spots was significantly higher in JIAU than in JIA patients or healthy controls. Particularly in JIAU patients, cluster analyses indicated a broad range of serum antibodies directed against ocular antigens, mostly in the iris proteome. Iris proteins frequently bound by serum antibodies in all groups were identified as tubulin beta chain, vimentin, ATP synthase subunit beta, actin, and L-lactate dehydrogenase B chain. Iris proteins exclusively bound by JIAU serum antibodies were heat shock cognate 71 kDa protein and keratin. Although serum autoantibody binding to ocular antigens was not disease-specific, a significant diversity of autoantibodies against a broad range of antigens, particularly from the iris tissue, was detected in JIAU patients. As the iris is a major site of inflammation in JIAU, the present data give further evidence that autoantibodies may be involved in JIAU immunopathology.

Perinatal events and development of juvenile idiopathic arthritis-associated uveitis.

Project description:Uveitis is one of the most common manifestations of juvenile idiopathic arthritis (JIA). Currently, JIA is associated with decreased gut microbiota diversity. Studies confirm that perinatal events can cause aberrant microbial colonization. The objective of this study is to determine if JIA is associated with perinatal events with a secondary focus on these variables to the development of JIA-uveitis. 369 patients with strabismus (n = 200) or JIA (n = 196) were included in the study. Completed surveys (JIA 37; strabismus 18) collected data about birth route, pregnancy and labor complications, JIA medications, and the presence of eye disorders. Analysis indicates that there is no relationship between JIA development and the perinatal events investigated. Similarly, no significance was found between JIA-uveitis and birth route or labor complications. Pregnancy complications, namely gestational diabetes (GD), were statistically higher in the JIA group with uveitis compared to JIA without uveitis. The data from this survey study showed that JIA-uveitis was highly associated with pregnancy complications, particularly with GD. However, no statistically significant association was found between JIA and route of delivery, labor complications, or pregnancy complications. Further studies are needed to understand the ways that GD interrelates with the development of uveitis in JIA patients.

A clearer vision: insights into juvenile idiopathic arthritis-associated uveitis.

Project description:The aim of this narrative review is to synthesize existing evidence-based knowledge on juvenile idiopathic arthritis-associated uveitis (JIA-U). We highlight epidemiology, pathophysiology, causes and genetics, risk factors, clinical features, diagnosis and screening, laboratory biomarkers, treatment options, trials with recent advances, and research challenges pertaining to JIA-U. The prevalence of JIA-U varies with different JIA subtypes, most frequently associated with the oligoarticular subtype. The risk factors involved in the development of JIA-U include younger age, antinuclear antibody (ANA) positivity, and the oligoarticular subtype of JIA, along with some specific major histocompatibility complex genes. Certain laboratory biomarkers, such as ANA, rheumatoid factor, interferon-λ, erythrocyte sedimentation rate, and transthyretin, have been used in JIA-U diagnosis, progress monitoring, and prognostication. Clinical features of JIA-U can range from asymptomatic to ophthalmic symptoms like redness, blurred vision, decreased visual acuity, hypopyon, and posterior uveitis, which can lead to retinal detachment and macular edema. The management protocol involves topical and systemic steroids, cycloplegics, disease-modifying antirheumatic drugs, biologic drugs, and surgical options. Early detection combined with prompt treatment is crucial to preventing irreversible vision loss in JIA-U.
