Clinical management algorithm of uveitis associated with juvenile idiopathic arthritis: interdisciplinary panel consensus

Childhood-Onset Non-Infectious Uveitis in the "Biologic Era". Results From Spanish Multicenter Multidisciplinary Real-World Clinical Settings

OBJECTIVE

To characterize and describe clinical experience with childhood-onset non-infectious uveitis.

STUDY DESIGN

A multicenter retrospective multidisciplinary national web-based registry of 507 patients from 21 hospitals was analyzed. Cases were grouped as immune disease-associated (IMDu), idiopathic (IDIu) or ophthalmologically distinct. Characteristics of juvenile idiopathic arthritis-associated (non-HLA-B27-related) uveitis (JIAu), IDIu, and pars planitis (PP) were compared.

RESULTS

IMDu (62.3%) and JIAu (51.9%) predominated in young females; and IDIu (22.7%) and PP (13.6%) in older children, without sex imbalance. Ocular complications occurred in 45.3% of cases (posterior synechiae [28%], cataracts [16%], band keratopathy [14%], ocular hypertension [11%] and cystoid macular edema [10%]) and were associated with synthetic (86%) and biologic (65%) disease-modifying antirheumatic drug (DMARD) use. Subgroups were significantly associated (p < 0.05) with different characteristics. JIAu was typically anterior (98%), insidious (75%), in ANA-positive (69%), young females (82%) with fewer complications (31%), better visual outcomes, and later use of uveitis-effective biologics. In contrast, IDIu was characteristically anterior (87%) or panuveitic (12.1%), with acute onset (60%) and more complications at onset (59%: synechiae [31%] and cataracts [9.6%]) and less DMARD use, while PP is intermediate, and was mostly bilateral (72.5%), persistent (86.5%) and chronic (86.8%), with more complications (70%; mainly posterior segment and cataracts at last visit), impaired visual acuity at onset, and greater systemic (81.2%), subtenon (29.1%) and intravitreal (10.1%) steroid use.

CONCLUSION

Prognosis of childhood uveitis has improved in the "biologic era," particularly in JIAu. Early referral and DMARD therapy may reduce steroid use and improve outcomes, especially in PP and IDIu.

Diagnosis and Management of Non-Infectious Uveitis in Pediatric Patients

Uveitis in children accounts for 5-10% of all cases. The causes vary considerably. Classically, uveitis is distinguished according to its infectious or inflammatory origin and whether it is part of a systemic disease or represents an isolated ocular disease. It is important to highlight the specificity of certain etiologies among children such as juvenile idiopathic arthritis. The development of visual function can potentially be hindered by amblyopia (children aged < 7 years), in addition to the usual complications (synechiae, macular edema) seen in adult patients. Moreover, the presentation of uveitis in children is often "silent" with few warning signs and few functional complaints from young children, which frequently leads to a substantial diagnostic delay. The diagnostic approach is guided by the presentation of the uveitis, which can be characterized by its location, and corresponds to the initial and main site of intraocular inflammation; its presentation, whether acute or chronic, granulomatous or not; and the response to treatment. Pediatricians have an important role to play and must be aware of the various presentations and etiologies of uveitis in children. Juvenile idiopathic arthritis is the most common etiology of pediatric non-infectious uveitis, but other causes must be recognized. Promptly initiated treatment before complications arise requires early diagnosis, recognition, and treatment. Any dependence on prolonged local corticosteroid therapy justifies discussing the introduction of a corticosteroid-sparing treatment considering the risk to develop corticoid-induced glaucoma and cataracts. Systemic corticosteroid therapy can be required for urgent control of inflammation in the case of severe uveitis. Long-lasting immunosuppressive treatment and biotherapies are most often prescribed at the same time to reinforce treatment efficacy and to prevent relapse and corticosteroid dependency. We review the different causes of uveitis, excluding infection, and the diagnostic and therapeutic management aimed at limiting the risk of irreversible sequelae.

Update on the systemic management of noninfectious uveitis in children and adolescents

Noninfectious uveitis (NIU) in children and adolescents is a rare but treatable cause of visual impairment in children. Treatments for pediatric NIU and their side effects, along with the risks of vision loss and the need for long-term disease monitoring, pose significant challenges for young patients and their families. Treatment includes local and systemic approaches and this review will focus on systemic therapies that encompass corticosteroids, conventional synthetic disease-modifying antirheumatic drugs (csDMARD), and biological disease-modifying antirheumatic drugs (bDMARD). Treatment is generally planned in a stepwise approach. Methotrexate is well-established as the preferential csDMARD in pediatric NIU. Adalimumab, an antitumor necrosis factor (TNF) agent, is the only bDMARD formally approved for pediatric NIU and has a good safety and efficacy profile. Biosimilars are gaining increasing visibility in the treatment of pediatric NIU. Other bDMARD with some evidence in literature for the treatment of pediatric NIU include infliximab, tocilizumab, abatacept, rituximab and, more recently, Janus kinase inhibitors. Important aspects of managing children on these systemic therapies include vaccination issues, risk of infection, and psychological distress. Also, strategies need to address regarding primary nonresponse/secondary loss of response to anti-TNF treatment, biological switching, and monitoring regimens for these drugs. Optimal management of pediatric uveitis involves a multidisciplinary team, including specialist pediatric uveitis and rheumatology nurses, pediatric rheumatologists, psychological support, orthoptic and optometry support, and play specialists.

Uveitis Associated with Juvenile Idiopathic Arthritis

Juvenile idiopathic arthritis (JIA) is the most common cause of uveitis in children. While symptoms are usually mild, persistent eye inflammation could lead to severe complications and impaired vision. It is essential that JIA patients at risk are diagnosed with uveitis early, receive adequate treatment, and avoid developing complications, such as cataract, glaucoma, and amblyopia. The purpose of this mini-review is to summarize the screening strategies and clinical management for JIA-associated uveitis (JIA-U) as well as the current state of molecular markers linked to this condition. Because glaucoma is one of the most common causes of visual loss in JIA-U, special focus will be put on this serious complication. We conclude by describing the current evidence regarding the long-standing question of whether chronic anterior uveitis without arthritis may be the same disease entity as JIA-U.

Methotrexate therapy associated with a reduced rate of new-onset uveitis in patients with biological-naïve juvenile idiopathic arthritis

OBJECTIVE

To study the effect of methotrexate (MTX) therapy on new-onset uveitis in patients with biological-naïve juvenile idiopathic arthritis (JIA).

METHODS

In this matched case-control study, we compared MTX exposure between cases with JIA-associated chronic uveitis (JIA-U) and patients with JIA and without JIA-U at the time of matching (controls). Data were collected from electronic health records of the University Medical Centre Utrecht, the Netherlands. Cases with JIA-U were matched 1:1 to JIA control patients based on JIA diagnosis date, age at JIA diagnosis, JIA subtype, antinuclear antibodies status and disease duration. The effect of MTX on JIA-U onset was analysed using a multivariable time-varying Cox regression analysis.

RESULTS

Ninety-two patients with JIA were included and characteristics were similar between cases with JIA-U (n=46) and controls (n=46). Both ever-use of MTX and exposure years were lower in cases with JIA-U than in controls. Cases with JIA-U significantly more often discontinued MTX treatment (p=0.03) and out of those who did, 50% afterwards developed uveitis within 1 year. On adjusted analysis, MTX was associated with a significantly reduced new-onset uveitis rate (HR: 0.35; 95% CI: 0.17 to 0.75). No different effect was observed between a low (<10 mg/m²/week) and standard MTX dose (≥10 mg/m²/week).

CONCLUSION

This study demonstrates an independent protective effect of MTX on new-onset uveitis in patients with biological-naïve JIA. Clinicians might consider early initiation of MTX in patients at high uveitis risk. We advocate more frequent ophthalmologic screening in the first 6-12 months after MTX discontinuation.

Perspectives of Therapeutic Drug Monitoring of Biological Agents in Non-Infectious Uveitis Treatment: A Review

Biological drugs, especially those targeting anti-tumour necrosis factor α (TNFα) molecule, have revolutionized the treatment of patients with non-infectious uveitis (NIU), a sight-threatening condition characterized by ocular inflammation that can lead to severe vision threatening and blindness. Adalimumab (ADA) and infliximab (IFX), the most widely used anti-TNFα drugs, have led to greater clinical benefits, but a significant fraction of patients with NIU do not respond to these drugs. The therapeutic outcome is closely related to systemic drug levels, which are influenced by several factors such as immunogenicity, concomitant treatment with immunomodulators, and genetic factors. Therapeutic drug monitoring (TDM) of drug and anti-drug antibody (ADAbs) levels is emerging as a resource to optimise biologic therapy by personalising treatment to bring and maintain drug concentration within the therapeutic range, especially in those patients where a clinical response is less than expected. Furthermore, some studies have described different genetic polymorphisms that may act as predictors of response to treatment with anti-TNFα agents in immune-mediated diseases and could be useful in personalising biologic treatment selection. This review is a compilation of the published evidence in NIU and in other immune-mediated diseases that support the usefulness of TDM and pharmacogenetics as a tool to guide clinicians’ treatment decisions leading to better clinical outcomes. In addition, findings from preclinical and clinical studies, assessing the safety and efficacy of intravitreal administration of anti-TNFα agents in NIU are discussed.

Tocilizumab in Juvenile Idiopathic Arthritis Associated Uveitis, a Narrative Review

Juvenile idiopathic arthritis (JIA) associated uveitis (JIA-U) is the most common extra-articular manifestation of JIA, affecting 10–15% of patients, especially in oligoarticular JIA where its course may be faint. Therefore, JIA-U is one of the most challenging pediatric uveitis, associated with major ocular morbidity and possibly leading to irreversible structural ocular damage and to vision-threatening complications. Adequate management is crucial for avoiding visual impairment complications. Since the introduction of biologic disease modifying anti-rheumatic drugs (bDMARDS), the visual prognosis of JIA-U has dramatically improved over the decades. Tumor necrosis factor-α (TNF-α) blockers are the most used bDMARDs in treating JIA-U with large evidence of efficacy. However, inadequate response to these agents, either due to intolerance or inefficacy, may be observed, requiring a swap to other classes of immunosuppressive agents, including anti-IL-6, anti-CD20, and, more recently, JAK inhibitors. Tocilizumab is a humanized monoclonal antibody to the interelukin-6 receptor preventing IL-6 from binding to its soluble and membrane-bound receptors. A growing body of literature provides promising results about the efficacy of intravenous and subcutaneous tocilizumab in the treatment of JIA-U. A narrative review of the literature on this topic will improve our knowledge on the potential use of tocilizumab in JIA-U.

Systematic review of clinical practice guidelines for uveitis

To facilitate the integration of eye care into universal health coverage, the WHO is developing a Package of Eye Care Interventions (PECI). Development of the PECI involves the identification of evidence-based interventions from relevant clinical practice guidelines (CPGs) for uveitis.

A systematic review of CPGs published on uveitis between 2010 and March 2020 was conducted. CPGs passing title and abstract and full-text screening were evaluated using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool and data on recommended interventions extracted using a standard data extraction sheet.

Of 56 CPGs identified as potentially relevant from the systematic literature search, 3 CPGs underwent data extraction following the screening stages and appraisal with the AGREE II tool. These CPGs covered screening for, monitoring and treating juvenile idiopathic arthritis (JIA)-associated uveitis, the use of adalimumab and dexamethasone in treating non-infectious uveitis, and a top-level summary of assessment, differential diagnosis and referral recommendations for uveitis, aimed at primary care practitioners. Many of the recommendations were based on expert opinion, though some incorporated clinical study and randomised controlled trial data.

There is currently sparse coverage of the spectrum of disease caused by uveitis within CPGs. This may partially be due to the large number of conditions with diverse causes and clinical presentations covered by the umbrella term uveitis, which makes numerous sets of guidelines necessary. The limited pool of CPGs to select from has implications for clinicians seeking guidance on clinical care strategies for uveitis.

Long-term follow-up of certolizumab pegol in uveitis due to immune-mediated inflammatory diseases: multicentre study of 80 patients

OBJECTIVES

To evaluate effectiveness and safety of certolizumab pegol (CZP) in uveitis due to immune-mediated inflammatory diseases (IMID).

METHODS

Multicentre study of CZP-treated patients with IMID uveitis refractory to conventional immunosuppressant. Effectiveness was assessed through the following ocular parameters: best-corrected visual acuity, anterior chamber cells, vitritis, macular thickness and retinal vasculitis. These variables were compared between the baseline, and first week, first, third, sixth months, first and second year.

RESULTS

We studied 80 (33 men/47 women) patients (111 affected eyes) with a mean age of 41.6±11.7 years. The IMID included were: spondyloarthritis (n=43), Behçet's disease (n=10), psoriatic arthritis (n=8), Crohn's disease (n=4), sarcoidosis (n=2), juvenile idiopathic arthritis (n=1), reactive arthritis (n=1), rheumatoid arthritis (n=1), relapsing polychondritis (n=1), CONCLUSIONS: CZP seems to be effective and safe in uveitis related to different IMID, even in patients refractory to previous biological drugs.

Psychological Effects and Quality of Life in Parents and Children with Jia-Associated Uveitis

Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disease common in children and young adults. Uveitis is the most frequent serious extra-articular JIA manifestation and can lead to severe ocular complications, vision loss, and permanent blindness. This study aims to evaluate the psychological condition and the quality of life of children affected by JIA associated with uveitis (JIA-U) and the repercussion of this condition on parents. Thirty children and adolescents with active uveitis (Uveitis group) and comorbid joint symptoms of JIA were referred to the Unit of Ophthalmology, Giovanni XXIII Hospital of Bari, and 30 age-matched healthy controls (Healthy group) were enrolled with their parents. Four questionnaires were administered: Child Behaviour Checklist (CBCL), Parent Stress Index in Short Form (PSI), Pediatric Quality of Life Inventory (PedsQL), and Coping Inventory for Stressful Situations (CISS). The data were collected from February 2021 to December 2021. No significant differences between the two groups in CBCL, PSI, or CISS tests were shown (p > 0.05). Conversely, significant differences between the two groups were observed in the PedsQL (p < 0.05). This study shows how several ocular complications, recurrent eye examinations, and the rigor of long-term treatment may negatively influence health-related quality of life in children with JIA-U.

Biologic therapies for juvenile idiopathic arthritis-associated uveitis

Juvenile idiopathic arthritis (JIA) is the most frequent rheumatic disease of childhood and uveitis is its most common extra-articular manifestation. JIA-associated uveitis (JIA-U) is one of the main causes of visual impairment in children and represents a major challenge for pediatrician and ophthalmologist, due to its insidious onset and sight-threatening complications. Topical glucocorticoids are the first line of treatment, followed by conventional disease-modifying anti-rheumatic drugs (DMARDs), usually methotrexate (MTX). In recent years, new biological drugs targeting specific molecules involved in disease pathogenesis, have significantly improved the prognosis of the disease, especially for cases refractory to conventional therapies. In this review we discuss the role of biological agents in JIA-U, focusing on cytokine blockers and cell-targeted therapies aimed to control ocular inflammation.

Management Strategies of Juvenile Idiopathic Arthritis-Associated Chronic Anterior Uveitis: Current Perspectives

Juvenile idiopathic arthritis (JIA) is the most common extraocular disease associated with pediatric uveitis. Despite the growing knowledge about the pathogenetic and clinical characteristics of the disease, it still remains a challenge for both the pediatric rheumatologist and ophthalmologist. Since uveitis is asymptomatic in most cases, it is generally detected by parents in a late phase of the disease when complications have occurred with consequent severe vision loss. Improvement in attentive screening and early treatment initiation to suppress inflammation has considerably reduced the sight-threatening outcomes of JIA-associated chronic anterior uveitis (JIA-CAU). Initial treatment with topical steroids is effective in most cases. However, more severe cases require the use of periocular or systemic corticosteroids, possibly leading to long-term complications. These include growth retardation, cataract and glaucoma. Systemic immunosuppressive agents are then employed in patients resistant to first-line therapy or to reduce steroid-associated complications. In this review, we will discuss the immunosuppressant agents currently employed for the treatment of the disease, including anti-tumor necrosis factor (TNF)α biologics approved or not by the regulatory agencies. We will also highlight how new therapeutic options like biologic targeting cytotoxic T-lymphocyte antigen-4 (CTLA-4) co-stimulatory molecule, interleukin-6 receptor (IL-6R) or B lymphocytes might represent exciting new options for patients resistant to conventional therapy. Finally, the potential use of janus kinase (JAK) inhibitors recently approved for the treatment of several inflammatory rheumatic diseases in adults will be also discussed.

Intraocular dendritic cells characterize HLA-B27-associated acute anterior uveitis

Uveitis describes a heterogeneous group of inflammatory eye diseases characterized by infiltration of leukocytes into the uveal tissues. Uveitis associated with the HLA haplotype B27 (HLA-B27) is a common subtype of uveitis and a prototypical ocular immune-mediated disease. Local immune mechanisms driving human uveitis are poorly characterized mainly due to the limited available biomaterial and subsequent technical limitations. Here, we provide the first high-resolution characterization of intraocular leukocytes in HLA-B27-positive (n = 4) and -negative (n = 2) anterior uveitis and an infectious endophthalmitis control (n = 1) by combining single-cell RNA-sequencing with flow cytometry and protein analysis. Ocular cell infiltrates consisted primarily of lymphocytes in both subtypes of uveitis and of myeloid cells in infectious endophthalmitis. HLA-B27-positive uveitis exclusively featured a plasmacytoid and classical dendritic cell (cDC) infiltrate. Moreover, cDCs were central in predicted local cell-cell communication. This suggests a unique pattern of ocular leukocyte infiltration in HLA-B27-positive uveitis with relevance to DCs.

Uveitis in Children and Adolescents

Childhood noninfectious uveitis leads to sight-threatening complications. Idiopathic chronic anterior uveitis and juvenile idiopathic arthritis-associated uveitis are most common. Inflammation arises from an immune response against antigens within the eye. Ophthalmic work-up evaluates anatomic involvement, disease activity, ocular complications, and disease course. Local and/or systemic glucocorticoids are initial treatment, but not as long-term sole therapy to avoid glucocorticoids-induced toxicity or persistent ocular inflammation. Children with recurrent, refractory, or severe disease require systemic immunosuppression with methotrexate and/or anti-tumor necrosis factor monoclonal antibody medications (adalimumab, infliximab). Goals of early detection and treatment are to optimize vision in childhood uveitis.

Summarizing current refractory disease definitions in rheumatoid arthritis and polyarticular juvenile idiopathic arthritis: systematic review

OBJECTIVES

To identify how refractory disease (or relevant terminology variations) in RA and polyarticular JIA (polyJIA) is defined and establish the key components of such definitions.

METHODS

Searches were undertaken of English-language articles within six medical databases, including manual searching, from January 1998 to March 2020 (PROSPERO: CRD42019127142). Articles were included if they incorporated a definition of refractory disease, or non-response, in RA/polyJIA, with clear components to the description. Qualitative content analysis was undertaken to describe refractory disease in RA/polyJIA and classify each component within each definition.

RESULTS

Of 6251 studies screened, 646 met the inclusion criteria; 581 of these applied non-response criteria while 65 provided refractory disease definitions/descriptions. From the non-response studies, 39 different components included various disease activity measures, emphasizing persistent disease activity and symptoms, despite treatment with one or more biologic DMARD (bDMARD). From papers with clear definitions for refractory disease, 41 components were identified and categorized into three key themes: resistance to multiple drugs with different mechanisms of action, typically two or more bDMARDs; persistence of symptoms and disease activity; and other contributing factors. The most common term used was 'refractory' (80%), while only 16.9% reported explicitly how their definition was generated (e.g. clinical experience or statistical methods).

CONCLUSION

Refractory disease is defined as resistance to multiple drugs with different mechanisms of action by persistence of physical symptoms and high disease activity, including contributing factors. A clear unifying definition needs implementing, as the plethora of different definitions makes study comparisons and appropriate identification of patients difficult.

Juvenile Idiopathic Arthritis Associated Uveitis

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.

Update on biologic therapies for juvenile idiopathic arthritis-associated uveitis

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease of childhood, and juvenile idiopathic associated uveitis (JIA-U) is the most frequently noted extra-articular manifestation. JIA-U can present asymptomatically and lead to ocular complications, so regular screening and monitoring are needed to prevent potentially sight-threatening sequelae. Topical glucocorticoids such as prednisolone acetate are usually the first line of treatment for anterior uveitis associated with JIA-U, but long-term use may be associated with cataract, ocular hypertension and glaucoma. Disease modifying anti-rheumatic drugs (DMARDs) such as methotrexate allow tapering of the corticosteroids to prevent long-term complications. Biologic therapies have been increasingly used as targeted therapies for JIA-U, particularly monoclonal antibodies targeting the proinflammatory cytokine TNF-α such as adalimumab and infliximab. One recent, multicenter, prospective, randomized clinical trial provided evidence of the efficacy of adalimumab with methotrexate for JIA-U compared to methotrexate alone. Another clinical trial studying the interleukin-6 inhibitor tocilizumab for JIA-U showed promise in tapering topical corticosteroids. Additionally, JAK inhibitors are emerging biologic therapies for JIA-U in patients refractory to TNF-α inhibitors, with a clinical trial assessing the efficacy of baricitinib for JIA-U underway. While clinical trials on these novel biologics are limited, further investigation of these agents may provide additional therapeutic options for JIA-U.

Monitoring and Treatment of Juvenile Idiopathic Arthritis-associated Uveitis: Brazilian Evidence-based Practice Guidelines

Purpose: To present a national guideline for ophthalmologic care and surveillance of juvenile idiopathic arthritis-associated uveitis (JIA-uveitis).Methods: Review article based on medical literature and the experience of an Expert Committee composed of members of the Brazilian Society of Pediatric Ophthalmology/Brazilian Council of Ophthalmology and the Brazilian Society of Pediatrics/Brazilian Society of Rheumatology. Studies with a high level of evidence were selected by searching the PubMed/Medline database. The final document was approved by the experts.Results: The main recommendations are that children/adolescents with JIA should undergo screening according to their risk factors. Ophthalmological checkups should also consider ocular inflammation and therapy. Topical glucocorticoids should be the first line of therapy, with systemic glucocorticoids acting as bridge treatments in severe uveitis. Methotrexate should be the first-line systemic therapy and anti-tumor necrosis factor (anti-TNF alpha) the second for uncontrolled uveitis.Conclusions: This evidence-based guideline for JIA-uveitis will be useful for both ophthalmology and rheumatology practice.

Update on noninfectious uveitis in children and its treatment

PURPOSE OF REVIEW

To give an overview of recently published articles covering risk factors, novel biomarkers and treatment for noninfectious uveitis in children.

RECENT FINDINGS

In the last few years, several genetic markers, serum biomarkers, aqueous humor markers, tear biomarkers and clinical factors have been identified, which are associated with childhood noninfectious uveitis. We describe the most important reports in this field that may help to tailor the screening and monitoring of this population in the future and might become the target of novel therapies. The advances in the biologic therapy of paediatric uveitis, thanks to evidence provided by the SYCAMORE, ADJUVITE and APTITUDE trials, offer new possibilities for the treatment of patients who fail methotrexate with adalimumab and tocilizumab. We discuss the importance of comprehensive outcome measures as proposed by the Multinational Interdisciplinary Working Group for Uveitis in Childhood (MIWGUC).

SUMMARY

Paediatric noninfectious uveitis is a sight-threatening condition and the identification of risk factors and novel biomarkers is critical for tailored management. Biologic therapies are revolutionizing the outcomes of patients resistant to conventional therapy. Increasing our knowledge of disease pathogenesis is crucial to improve targeting of screening to those at highest risk and stratification of treatments.

Efficacy and Safety of Anti-TNFα Therapy for Uveitis Associated with Juvenile Idiopathic Arthritis: A Systematic Review and Meta-Analysis

Introduction

To investigate the efficacy and safety of anti-TNFα therapy in patients with juvenile idiopathic arthritis associated uveitis (JIA-U).

Methods

Embase, PubMed, Cochrane Library, and Web of Science were systematically searched for studies reporting anti-TNFα treatment in patients with JIA-U. The primary outcome was the control of intraocular inflammation (CII). The pooled proportion of CII was assessed by the random-effects method when I² > 50%, otherwise, by the fixed-effect method. This study was registered with PROSPERO (CRD42020161749).

Results

Three randomized clinical trials (RCTs), twelve case series, three retrospective cohort studies, and three case reports were identified. A total of 399 patients were receiving anti-TNFα therapy, of which 201 patients were treated with adalimumab (ADA), 139 with infliximab (IFX), 36 with etanercept (ETA), 20 with golimumab (GLM), and 3 with certolizumab pegol (CZP). The pooled proportions of CII on observational studies were 82% (95% CI 63–96%) in patients receiving ADA, 56% (95% CI 30–80%) in IFX, 38% (95% CI 8–73%) in ETA and 65% (95% CI 42–86%) in GLM, respectively. All three patients treated with CZP reached improved activity. ADA therapy led to a significantly higher proportion of CII compared to IFX therapy (χ² = 26.24, P < 0.001), or to ETA therapy (χ² = 13.43, P < 0.001); but no statistical difference was observed between IFX and ETA (χ² = 0.13, P = 0.71). As to safety, most reported adverse events were tolerable and two cohort studies consistently showed that ADA was safer than IFX.

Conclusions

The existing evidence suggests that ADA is better than IFX regarding efficacy and safety. The effectiveness of IFX is higher than ETA with no statistical difference. GLM and CZP may be proxies for ADA but the evidence is limited.

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

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).

Bilateral 0.19 mg Fluocinolone Acetonide Intravitreal Implant in the Successful Treatment of Juvenile Idiopathic Arthritis-Associated Uveitis and Secondary Macular Oedema: A Case Report and Review of Intravitreal Therapies

Introduction

Treatment of juvenile idiopathic arthritis (JIA)-associated uveitis necessitates the use of long-term corticosteroids or immunosuppressive agents, each of which poses their own significant side effect profile. Initial treatment requires intensive topical glucocorticoids, with a step-up approach employing immunosuppressive agents for those cases with poor response or high-risk complications such as macular oedema. To date, there is minimal evidence to support a specific approach to such complicated subgroups. We present the first case to successfully employ the 0.19 mg fluocinolone acetonide implant (ILUVIEN^®, Alimera Sciences, Hampshire, UK) as a novel device for prolonged intravitreal administration of disease-modifying agents for patients with JIA complicated by uveitis.

Methods

This retrospective case report describes a 20-year old woman diagnosed with oligoarticular JIA complicated by chronic uveitis and associated cystoid macular oedema (CMO). Considering factors including the patient’s non-compliance, age, lens status, non-steroid response, and good response to short-term intravitreal steroid therapy, the 0.19 mg fluocinolone acetonide intravitreal implant was deemed an appropriate step-up treatment option.

Results

At 12-month follow-up, the left eye (OS) showed an improvement in visual acuity to 6/15 − 1 from 6/60 + 1 (0.42 from 0.98 logMAR) (pre-insertion) and a reduction in central retinal thickness (CRT) of 199 μm from 471 μm. The right eye (OD), treated 10 months later, showed an improvement in visual acuity to 6/7.5 from 6/24 − 1 (0.10 from 0.56 LogMAR) and a reduction in CRT of 327 μm 6 months after treatment.

Conclusion

In this case, the 0.19 mg fluocinolone acetonide implant provided safe and effective long-term treatment of JIA-associated uveitis and secondary CMO. This potentially offers an alternative approach to complex cases that show good response to short-term corticosteroid use.

[Immunosuppressive therapy in severe or chronic pediatric uveitis: Review of the literature]

Immunosuppressants are prescribed for pediatric uveitis in cases of severe involvement affecting the prognosis for vision or life, in cases of recurrent or chronic uveitis to achieve corticosteroid sparing, or in cases of corticosteroid resistance. Immunosuppressants used in children include antimetabolites (methotrexate, mycophenolate mofetil, azathioprine), cyclosporine, tacrolimus, and biologics, including infliximab, adalimumab, anakinra, canakinumab, and tocilizumab. The mechanisms of action and indications of the various immunosuppressants are described in this review.

Widefield Fundus Fluorescein Angiography Features of Uveitis Associated with Juvenile Idiopathic Arthritis

PURPOSE

To evaluate the wide-field fundus fluorescein angiography (WFA) characteristics of uveitis associated with juvenile idiopathic arthritis (JIA-uveitis).

METHODS

Retrospective review of records. WFA with Spectralis (Heidelberg) of JIA-uveitis patients were analyzed using the scoring system by Angiography Scoring for Uveitis Nomenclature.

RESULTS

Thirty-seven eyes of 20 patients were studied. A total score of at least 1 was noted in 27 eyes (72.97%). WFA features included optic disc hyperfluorescence (51.35%), macular leakage (27.03%), retinal vascular staining/leakage at posterior pole (27.03%) and peripheral retina (64.86%), capillary leakage at the posterior pole (37.84%), and peripheral retina (59.46%). A decision to change the management plan was made in 8 of 9 patients with bilateral quiet anterior chambers after WFA results.

CONCLUSION

More than 70% of JIA-uveitis eyes showed some WFA-evidence of posterior segment inflammation, which changed the course of therapy for a major proportion of patients with no clinically active anterior chamber inflammation.

Long-term Follow-up and Optimization of Infliximab in Refractory Uveitis Due to Behçet Disease: National Study of 103 White Patients

OBJECTIVE

In a large series of White patients with refractory uveitis due to Behçet disease (BD) being treated with infliximab (IFX), we assessed (1) long-term efficacy and safety of IFX, and (2) IFX optimization when ocular remission was achieved.

METHODS

Our multicenter study of IFX-treated patients with BD uveitis refractory to conventional immunosuppressant agents treated 103 patients/185 affected eyes with IFX as first biologic therapy in the following intervals: 3-5 mg/kg intravenous at 0, 2, 6, and then every 4-8 weeks. The main outcome variables were analyzed at baseline, first week, first month, sixth month, first year, and second year of IFX therapy. After remission, based on a shared decision between patient and clinician, IFX optimization was performed. Efficacy, safety, and cost of IFX therapy were evaluated.

RESULTS

In the whole series (n = 103), main outcome variables showed a rapid and maintained improvement, reaching remission in 78 patients after a mean IFX duration of 31.5 months. Serious adverse events were observed in 9 patients: infusion reactions (n = 4), tuberculosis (n = 1), Mycobacterium avium pneumonia (n = 1), severe oral ulcers (n = 1), palmoplantar psoriasis (n = 1), and colon carcinoma (n = 1). In the optimization subanalysis, the comparative study between optimized and nonoptimized groups showed (1) no differences in clinical characteristics at baseline, (2) similar maintained improvement in most ocular outcomes, (3) lower severe adverse events, and (4) lower mean IFX costs in the optimized group (€4826.52 vs €9854.13 per patient/yr).

CONCLUSION

IFX seems to be effective and relatively safe in White patients with refractory BD uveitis. IFX optimization is effective, safe, and cost-effective.

Design of an algorithm for the diagnostic approach of patients with joint pain

BACKGROUND

Rheumatic diseases are a reason for frequent consultation with primary care doctors. Unfortunately, there is a high percentage of misdiagnosis.

OBJECTIVE

To design an algorithm to be used by primary care physicians to improve the diagnostic approach of the patient with joint pain, and thus improve the diagnostic capacity in four rheumatic diseases.

METHODS

Based on the information obtained from a literature review, we identified the main symptoms, signs, and paraclinical tests related to the diagnosis of rheumatoid arthritis, spondyloarthritis with peripheral involvement, systemic lupus erythematosus with joint involvement, and osteoarthritis. We conducted 3 consultations with a group of expert rheumatologists, using the Delphi technique, to design a diagnostic algorithm that has as a starting point "joint pain" as a common symptom for the four diseases.

RESULTS

Thirty-nine rheumatologists from 18 countries of Ibero-America participated in the Delphi exercise. In the first consultation, we presented 94 items to the experts (35 symptoms, 31 signs, and 28 paraclinical tests) candidates to be part of the algorithm; 74 items (25 symptoms, 27 signs, and 22 paraclinical tests) were chosen. In the second consultation, the decision nodes of the algorithm were chosen, and in the third, its final structure was defined. The Delphi exercise lasted 8 months; 100% of the experts participated in the three consultations.

CONCLUSION

We present an algorithm designed through an international consensus of experts, in which Delphi methodology was used, to support primary care physicians in the clinical approach to patients with joint pain. Key Points • We developed an algorithm with the participation of rheumatologists from 18 countries of Ibero-America, which gives a global vision of the clinical context of the patient with joint pain. • We integrated four rheumatic diseases into one tool with one common symptom: joint pain. It is a novel tool, as it is the first algorithm that will support the primary care physician in the consideration of four different rheumatic diseases. • It will improve the correct diagnosis and reduce the number of paraclinical tests requested by primary care physicians, in the management of patients with joint pain. This point was verified in a recently published study in the journal Rheumatology International (reference number 31).

Similarities in clinical course and outcome between juvenile idiopathic arthritis (JIA)-associated and ANA-positive idiopathic anterior uveitis: data from a population-based nationwide study in Germany

BACKGROUND

To analyze whether ANA-positive idiopathic anterior uveitis differs from JIA-associated uveitis concerning clinical course, response to treatment, and disease outcome.

METHODS

Prospective study of the National Paediatric Rheumatological Database (NPRD) including its uveitis add-on module from the years 2002 to 2016. Cross-sectional data from the years 2002 to 2016 were analyzed. Patients with JIA-associated uveitis and with ANA-positive idiopathic anterior uveitis were included and the disease manifestation investigated in terms of uveitis characteristics and disease course.

RESULTS

Of the total cohort of 34,458 patients enrolled in the NPRD, including 3551 patients with uveitis, those with detailed uveitis documentation were taken into account: 62 ANA-positive patients with idiopathic anterior uveitis (group 1), 688 patients with initial uveitis diagnosis after JIA onset (group 2), and 61 JIA patients with initial uveitis diagnosis before arthritis onset (group 3). Anterior uveitis was documented in 100%, 94%, and 80% of patients and with insidious onset of uveitis flare in 50%, 70.9%, and 56.1% each in groups 1, 2, and 3, respectively. Use of topical or systemic corticosteroids and conventional synthetic or biological DMARDs did not significantly differ between the patient groups, either at the initial or the 2-year follow-up (2-FU) visits (mean 2 years, each p > 0.05). At 2-FU, uveitis inactivity was achieved in 64.7%, 55.8%, and 61.5% of patients in groups 1, 2, and 3 (p > 0.05). Uveitis-related complications were more frequent at the initial visit and at 2-FU in groups 1 and 3, as compared to group 2.

CONCLUSIONS

ANA-positive idiopathic uveitis and JIA-associated uveitis do not significantly differ concerning clinical course of uveitis, treatment, and response to corticosteroids and DMARDs.

Phenotype of Innate Immune Cells in Uveitis Associated with Axial Spondyloarthritis- and Juvenile Idiopathic Arthritis-associated Uveitis

Purpose: To analyze circulating immune cells in patients with anterior uveitis (AU) associated to axial spondyloarthritis (SpA), or juvenile idiopathic arthritis (JIA).Methods: Venous blood samples were collected from healthy controls (n = 16), and either SpA (n = 19) or JIA (n = 23) patients with associated anterior uveitis (AU) during active flare, or after ≥3 months of inactivity. Frequencies of CD56⁺, MHC-I⁺, and S100A9⁺ monocytes, CCR7⁺ dendritic cells, CD56^+dim natural killer (NK) cells and CD3⁺CD56^bright T-cells were analyzed via flow cytometry. Serum S100A8/A9 levels were determined via ELISA.Results: SpA patients showed a reduced frequency of CD56^+dim NK cells during uveitis activity, a constitutively activated monocyte phenotype, and elevated S100A8/A9 serum levels. In contrast, JIAU patients showed elevated frequencies of CD56⁺ monocytes and CCR7⁺ DC.Conclusion: Phenotype of peripheral immune cells differ between patients, probably contributing to different courses of acute onset AU in SpA and insidious onset AU in JIAU patients.Abbreviations: AU: anterior uveitis, AR: arthritis, JIA: juvenile idiopathic arthritis, SpA: axial spondyloarthritis.

Recommendations for the Management of Uveitis Associated With Juvenile Idiopathic Arthritis: The Czech and Slovak adaptation of SHARE Initiative

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children and uveitis is its most important extra-articular manifestation. Evidence-based recommendations are available only to a limited extent and therefore JIA associated uveitis management is mostly based on physicians experience. Consequently, treatment practices differ widely, both nationally and internationally. Therefore, an effort to optimize and publish recommendations for the care of children and young adults with rheumatic diseases was launched in 2012 as part of the international project SHARE (Single Hub and Access Point for Pediatric Rheumatology in Europe) to facilitate clinical practice for paediatricians and (paediatric) rheumatologists. The aim of this work was to translate published international SHARE recommendations for the diagnosis and treatment of JIA associated uveitis and to adapt them for use in the Czech and Slovak Republics. International recommendations were developed according to the standard methodology of the European League against Rheumatism (EULAR) by a group of nine experienced paediatric rheumatologists and three experts in ophthalmology. It was based on a systematic literature review and evaluated in the form of an online survey and subsequently discussed using a nominal group technique. Recommendations were accepted if &gt; 80% agreement was reached (including all three ophthalmologists). A total of 22 SHARE recommendations were accepted: 3 on diagnosis, 5 on disease activity assessment, 12 on treatment and 2 on future recommendations. Translation of the original text was updated and modified with data specific to the czech and slovak health care systems and supplemented with a proposal for a protocol of ophthalmological dispensarization of paediatric JIA patients and a treatment algorithm for JIA associated uveitis. Conclusion: The aim of the SHARE initiative is to improve and standardize care for paediatric patients with rheumatic diseases across Europe. Therefore, recommendations for the diagnosis and treatment of JIA-associated uveitis have been formulated based on the evidence and agreement of leading European experts in this field.

Treating juvenile idiopathic arthritis (JIA)-related uveitis beyond TNF-α inhibition: a narrative review

Chronic anterior uveitis is the most frequent among extra-articular manifestations of juvenile idiopathic arthritis (JIA) and a relevant cause of ocular morbidity in children. Asymmetric arthritis, early onset disease, female sex, and anti-nuclear antibody (ANA) positivity are counted among risk factors for developing this complication. It usually has insidious onset and asymptomatic chronic-relapsing course, but the persistence of low-grade chronic inflammation can lead to irreversible structural ocular damage and to vision-threatening complications. For such reasons, achieving a complete absence of inflammation through early targeted and aggressive treatments is a primary therapeutic goal in these patients. This review is aimed at summarizing scientific evidence about biologic rescue therapy of JIA-related uveitis in patients who fail to achieve clinical remission, in spite of being treated with conventional disease-modifying anti-rheumatic drugs (cDMARDs) and at least one biologic tumor necrosis factor (TNF)-α inhibitor. Interleukin (IL)-6 inhibition appears a promising and safe option for refractory JIA-related uveitis. Abatacept and rituximab proved to be beneficial as well, but their efficacy together with some safety concerns needs to be more extensively evaluated.

Juvenile idiopathic arthritis-associated uveitis

Juvenile idiopathic arthritis (JIA) is the commonest rheumatic disease in children and JIA-associated uveitis its most frequent extra-articular manifestation. The uveitis is potentially sight-threatening and so carries a considerable risk of morbidity. The commonest form of uveitis seen in JIA is chronic anterior uveitis which is almost always asymptomatic in the initial stages. Therefore, screening for JIA-associated uveitis in at-risk patients is essential. The aim of early detection and treatment is to minimise intra-ocular inflammation and avoid complications leading to visual loss, resulting from both disease activity and medications. There is increasing evidence for the early introduction of systemic immunosuppressive therapies in order to reduce topical and systemic glucocorticoid use. Two randomised controlled trials of adalimumab in JIA-associated uveitis provide convincing evidence for the use of this biologic in patients who fail to respond adequately to methotrexate. Tocilizumab and baricitinib are being investigated as alternatives to anti-tumour necrosis factor drugs.

Earlier use of systemic immunosuppression is associated with fewer ophthalmic surgeries in paediatric non-infectious uveitis

Background/aims

There is a paucity of large trials investigating the effect of management strategies for paediatric non-infectious uveitis on complications requiring surgery. The purpose of our study is to investigate whether earlier initiation of systemic immunosuppression in paediatric non-infectious uveitis is associated with fewer ophthalmic surgeries.

Methods

A retrospective review was conducted on 48 children with non-infectious uveitis assessed in 1998–2013. Patients were divided into uveitis diagnosed before December 2008 (group 1) and after January 2009 (group 2). Duration from uveitis onset to methotrexate initiation (U-MTX) and biological addition (U-Biologic) were reviewed. Follow-up visits with topical corticosteroids >3 times daily and active uveitis (≥1+ cells) during 3.5 years were documented. The main outcome measure was the need for ≥1 ophthalmic surgery at 3.5 years.

Results

In group 1, 69.5% of patients required ≥1 ophthalmic surgery at 3.5 years versus 26.9% in group 2 (p=0.005). U-MTX was 28.9±11.8 weeks and 14.2±10.0 weeks for groups 1 and 2 (p=0.028). U-Biologic was 134.6±46.0 weeks and 82.3±43.3 weeks for groups 1 and 2 (p=0.0016). Corticosteroid use >3 times daily was 85.9±52.7 weeks and 14.6±11.1 weeks for groups 1 and 2. Multivariate regression showed methotrexate initiation within 6 months of uveitis onset lowered the likelihood of needing ophthalmic surgery at 3.5 years (OR=6.2, 95% CI 1.2 to 33.4; p=0.033). Univariate regression demonstrated biological addition within 18 months of uveitis onset reduced the likelihood of requiring ophthalmic surgery (OR 12.57, 95% CI 1.28 to 123.48; p=0.030).

Conclusion

Earlier control of uveitis by addition of immunosuppressive therapy reduced the need for ophthalmic surgery.

Juvenile idiopathic arthritis-associated uveitis: a retrospective analysis from a centre of South Italy

PURPOSE

To investigate the clinical and laboratory characteristics of the children affected by juvenile idiopathic arthritis (JIA) who developed uveitis.

METHODS

In this retrospective study, we have examined data of 109 patients aged from 3 to 16 years, affected by JIA and followed at Paediatrics Rheumatology Clinic and Ophthalmology Clinic of University Hospital of Messina in the period from 2007 to 2017. The main outcome measures were clinical and laboratory findings related to JIA and ocular involvement. The prevalence of ocular signs and symptoms was determined and correlated with age.

RESULTS

Twenty-one (19.3%) subjects developed uveitis. Two different peaks of age with ocular involvement were registered. The first occurred between 4 and 6 years and the second between 10 and 12 years. All subjects in the first group resulted to be female, presented oligoarticular arthritis and chronic anterior uveitis. In the second group, the 84% of patients were male with different types of JIA and acute anterior uveitis. The prevalence of ocular complications was higher in the first group.

CONCLUSIONS

Two peaks of age emerged and were characterized by different clinical outcomes of arthritis and ocular involvement. The first occurred between 4 and 6 years and interested females affected by oligoarticular JIA who develop chronic anterior uveitis. The second appeared at 10-12 years and interested older males affected by different types of JIA with acute anterior uveitis. Early diagnosis and cooperation between paediatric rheumatologist and ophthalmologist are of great importance in the proper management of JIA children with uveitis.

Update on the management of uveitis in children: an overview for the clinician

INTRODUCTION

Pediatric uveitis comprises a range of ocular inflammatory diseases that may lead to vision impairment, often due to ocular complications from the disease itself or side effects of therapies. The impact on vision, visual functioning, and vision-related quality-of-life over the lifetime horizon can be substantial, underscoring the importance of appropriate ophthalmic evaluation, diagnostic testing and treatment. This review focuses on the anatomic classification, laboratory diagnosis, associated systemic diseases, and management of pediatric uveitis.

AREAS COVERED

A review of the literature was performed to synthesize our current understanding of the anatomic classification of pediatric uveitis, disease epidemiology, associated systemic diseases, and management principles. We also review important corticosteroid-sparing strategies including non-biologic and biologic agents such as the anti-tumor necrosis factor (TNF)-alpha family of medications, given their key role in the treatment of pediatric uveitis, particularly juvenile idiopathic arthritis (JIA). Recent advances in the assessment of vision-related quality-of-life using the Effects of Youngsters' Eyesight on Quality of Life (EYE-Q) instrument are discussed.

EXPERT OPINION

Pediatric uveitis can lead to long-term vision impairment if not appropriately screened and treated. JIA is the most common systemic disease associated with uveitis, is typically asymptomatic, and thus requires rigorous screening to detect uveitis and avoid secondary ocular complications. While topical and systemic corticosteroids are useful for the acute treatment of uveitis, the disease chronicity of many pediatric uveitis syndromes including JIA, often warrants early escalation of therapy to immunosuppressive medications including methotrexate (MTX) and anti-TNF-alpha inhibitors. Future directions include an improved understanding of risk factors for uveitis and better metrics to evaluate the impact of disease on vision-related quality-of-life of pediatric uveitis patients.

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

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.

Areas of agreement in the management of childhood non-infectious chronic anterior uveitis in the UK

BACKGROUND/AIMS

There is a paucity of high-level evidence to support the management of childhood uveitis, particularly for those children without juvenile idiopathic arthritis uveitis (JIA). We undertook a modified Delphi consensus exercise to identify agreement in the management of chronic anterior uveitis (CAU), the most common manifestation of childhood disease.

METHODS

A four-round, two-panel process was undertaken between June and December 2017. Paediatric uveitis specialists identified through multiple sources, including a multicentre network (the Paediatric Ocular Inflammation Group), were invited to participate. They were asked whether they agreed with items derived from existing guidelines on the management of JIA-U when extrapolated to the population of all children with CAU. Consensus was defined as agreement greater than or equal to 75% of respondents.

RESULTS

26 of the 38 (68%) invited specialists participated with the exercise, and response rates were 100% for rounds one to three, and 92% for round four. Consensus was reached on 23 of the 44 items. Items for which consensus was not reached included management at presentation, use of systemic and periocular steroids for children with severe disease and the role of conventional steroid sparing immunosuppressants beyond methotrexate.

CONCLUSION

The areas of management uncertainty at the level of the group, as indicated by absence of consensus, reflect the areas where the evidence base is particularly poor. Our findings identify the key areas for the future research needed to ensure better outcomes for this blinding childhood ocular inflammatory disorders.

2019 American College of Rheumatology/Arthritis Foundation Guideline for the Screening, Monitoring, and Treatment of Juvenile Idiopathic Arthritis-Associated Uveitis

OBJECTIVE

To develop recommendations for the screening, monitoring, and treatment of uveitis in children with juvenile idiopathic arthritis (JIA).

METHODS

Pediatric rheumatologists, ophthalmologists with expertise in uveitis, patient representatives, and methodologists generated key clinical questions to be addressed by this guideline. This was followed by a systematic literature review and rating of the available evidence according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology. A group consensus process was used to compose the final recommendations and grade their strength as conditional or strong.

RESULTS

Due to a lack of literature with good quality of evidence, recommendations were formulated on the basis of available evidence and a consensus expert opinion. Regular ophthalmic screening of children with JIA is recommended because of the risk of uveitis, and the frequency of screening should be based on individual risk factors. Regular ophthalmic monitoring of children with uveitis is recommended, and intervals should be based on ocular examination findings and treatment regimen. Ophthalmic monitoring recommendations were strong primarily because of concerns of vision-threatening complications of uveitis with infrequent monitoring. Topical glucocorticoids should be used as initial treatment to achieve control of inflammation. Methotrexate and the monoclonal antibody tumor necrosis factor inhibitors adalimumab and infliximab are recommended when systemic treatment is needed for the management of uveitis. The timely addition of nonbiologic and biologic drugs is recommended to maintain uveitis control in children who are at continued risk of vision loss.

CONCLUSION

This guideline provides direction for clinicians and patients/parents making decisions on the screening, monitoring, and management of children with JIA and uveitis, using GRADE methodology and informed by a consensus process with input from rheumatology and ophthalmology experts, current literature, and patient/parent preferences and values.

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

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.

[Uveitis in juvenile idiopathic arthritis]

BACKGROUND

Uveitis is the most common extra-articular manifestation of juvenile idiopathic arthritis (JIA). It occurs, according to German registry data, in around 12% of JIA patients and can lead to a loss of vision, especially in cases of delayed diagnosis and/or inadequate therapy.

OBJECTIVE

A review of current aspects of diagnosis and therapy was carried out.

MATERIAL AND METHODS

This is a review article of the current literature.

RESULTS

The risk of uveitis is significantly elevated in patients with an oligoarticular course of JIA, ANA positivity and young age at onset of JIA. During the mostly asymptomatic course of uveitis severe complications, such as cataracts, glaucoma or macular edema can occur, limiting visual acuity. Early detection of uveitis and interdisciplinary cooperation of uveitis specialists and pediatric rheumatologists is of major importance to ensure a favorable long-term prognosis. The initial therapy consists of topical steroids; however, in cases of insufficient response or complicated course of uveitis, conventional synthetic (mainly methotrexate) or biological disease-modifying antirheumatic drugs (bDMARDs) are required. In respect to bDMARDs, the highest evidence exists for treatment with adalimumab; however, depending on the clinical course of disease, other bDMARDs, such as infliximab, golimumab, tocilizumab, abatacept or rituximab may also have a beneficial effect. Despite these treatment options, uveitis or arthritis may frequently persist into adult age. Adequate and early recognition and treatment of uveitis-related complications is of major importance to ensure a good long-term visual prognosis.

CONCLUSION

Early diagnosis of JIA-associated uveitis and early implementation of effective treatment, especially steroid-sparing DMARD therapy, aims at achieving uveitis inactivity and prevention of ocular damage.

Update of the evidence based, interdisciplinary guideline for anti-inflammatory treatment of uveitis associated with juvenile idiopathic arthritis

BACKGROUND

Uveitis in juvenile idiopathic arthritis (JIAU) is frequently associated with the development of complications and visual loss. Topical corticosteroids are the first line therapy, and disease modifying anti-rheumatic drugs (DMARDs) are commonly used. However, treatment has not been standardized.

METHODS

Interdisciplinary guideline were developed with representatives from the German Ophthalmological Society, Society for Paediatric Rheumatology, Professional Association of Ophthalmologists, German Society for Rheumatology, parents' group, moderated by the Association of the Scientific Medical Societies in Germany. A systematic literature analysis in MEDLINE was performed, evidence and recommendations were graded, an algorithm for anti-inflammatory treatment and final statements were discussed in a consensus meeting (Nominal Group Technique), a preliminary draft was fine-tuned and discussed thereafter by all participants (Delphi procedure).

RESULTS

Consensus was reached on recommendations, including a standardized treatment strategy according to uveitis severity in the individual patient. Thus, methotrexate shall be introduced for uveitis not responding to low-dose (≤ 2 applications/day) topical corticosteroids, and a TNFalpha antibody (preferably adalimumab) used, if uveitis inactivity is not achieved. In very severe active uveitis with uveitis-related deterioration of vision, systemic corticosteroids should be considered for bridging until DMARDs take effect. If TNFalpha antibodies fail to take effect or lose effect, another biological should be selected (tocilizumab, abatacept or rituximab). De-escalation of DMARDs should be preceded by a period of  ≥ 2 years of uveitis inactivity.

CONCLUSIONS

An interdisciplinary, evidence-based treatment guideline for JIAU is presented.

Timing of infliximab and adalimumab initiation despite methotrexate in children with chronic non-infectious anterior uveitis

AIMS

Methotrexate (MTX) is standard treatment in pediatric chronic anterior uveitis (CAU). Addition of tumor necrosis factor-α inhibitors (TNFi) is often needed. We describe the timing and risk factors for TNFi use in children with CAU on MTX.

METHODS

In this retrospective study, we reviewed 51 records, and 46 met inclusion criteria. Primary outcome was the addition of TNFi due to active CAU per Standardization of Uveitis Nomenclature criteria. Time to TNFi and factors associated with their addition were assessed using survival analysis models.

RESULTS

Of 46 children treated with MTX for uveitis (36 juvenile idiopathic arthritis-associated uveitis, 10 idiopathic CAU), 72% had ocular complications. MTX was started a median of 5.0 months, and TNFi 43 months from uveitis diagnosis. Kaplan-Meier estimates suggest that cumulatively, 12% (95% CI: 4-23%) start TNFi within 6 months of MTX, 21% (12-37%) within 1 year, and 39% (24-54%) within 2 years. On Cox Proportional Hazard regression analysis, children with idiopathic CAU required TNFi earlier in their uveitis course (at 3 months (Hazard Ratio 6.06; 95% confidence interval (1.25-29.41))). Females appeared less likely to require TNFi early. Children treated in 2012 and later were more likely to receive TNFi earlier than those treated before 2012.

CONCLUSION

Little is known about optimal time to initiate treatment or factors associated with the need to add TNFi in children on MTX. Children with idiopathic CAU and males required TNFi earlier in their course. Factors associated with these potential risk factors for TNFi warrant further investigation.

Glucocorticoid treatment in juvenile idiopathic arthritis

Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease of joints in childhood. Glucocorticoids are being used in JIA treatment effectively for decades. Although systemic glucocorticoid use decreased with the introduction of biologic drugs, intraarticular glucocorticoid injections (IAGI) with nonsteroidal anti-inflammatory drugs and non-biologic disease modifying anti-rheumatic drugs (DMARDs) still remain the primary treatment in JIA, especially in oligoarticular subcategory. Systemic glucocorticoids are used mainly for severe JIA-associated complications such as macrophage activation syndrome (MAS), myocarditis, pericarditis, pleuritis, peritonitis, and severe anemia; as bridging therapy while waiting for the full therapeutic effect of DMARDs; and in certain occasions for patients with severe refractory uveitis. Since glucocorticoid administration is associated with many adverse events, it is important to use glucocorticoids in an optimum way balancing the risks and benefits. The aim of this review is to summarize the current knowledge on glucocorticoid treatment in JIA. A comprehensive literature search was conducted utilizing the Cochrane Library and MEDLINE/PubMed databases. The main topics include mechanism of action, dose, duration, adverse events, vaccination during glucocorticoid treatment, the place of glucocorticoids in JIA treatment guidelines and consensus treatment plans, glucocorticoid use in JIA-associated uveitis, MAS, and IAGI. Data from the literature provide guidance on how to use glucocorticoids in JIA treatment especially for IAGI and systemic use in systemic JIA and MAS. However, there is lack of evidence and need for prospective randomized studies in most parts including the indications in different JIA subcategories, optimum dose/route of administration/duration of treatment, and tapering strategies.

Juvenile arthritis management in less resourced countries (JAMLess): consensus recommendations from the Cradle of Humankind

Juvenile idiopathic arthritis (JIA) is the most prevalent chronic rheumatic disease in children and young people (CYP) and a major cause of pain and disability. The vast majority of the world's children and their families live in less resourced countries (LRCs) and face significant socioeconomic and healthcare challenges. Current recommendations for standards of care and treatment for children with JIA do not consider children living in less resourced countries. In order to develop appropriate recommendations for the care of CYP with JIA in less resourced countries a meeting of experienced pediatric rheumatologists from less resourced countries was convened with additional input from a steering group of international pediatric rheumatologists with experience in developing recommendations and standards of care for JIA. Following a needs assessment survey of healthcare workers caring for CYP with JIA in LRC, a literature review was carried out and management recommendations formulated using Delphi technique and a final consensus conference. Responses from the needs assessment were received from 121/483 (25%) practitioners from 25/49 (51%) less resourced countries. From these responses, the initial 84 recommendations were refined and expanded through a series of 3 online Delphi rounds. A final list of 90 recommendations was proposed for evaluation. Evidence for each statement was reviewed, graded, and presented to the consensus group. The degree of consensus, level of agreement, and level of evidence for these recommendations are reported. Recommendations arrived at by consensus for CYP with JIA in less resourced countries cover 5 themes: (1) diagnosis, (2) referral and monitoring, (3) education and training, (4) advocacy and networks, and (5) research. Thirty-five statements were drafted. All but one statement achieved 100% consensus. The body of published evidence was small and the quality of evidence available for critical appraisal was low. Our recommendations offer novel insights and present consensus-based strategies for the management of JIA in less resourced countries. The emphasis on communicable and endemic diseases influencing the diagnosis and treatment of JIA serves as a valuable addition to existing JIA guidelines. With increasing globalization, these recommendations as a whole provide educational and clinical utility for clinicians worldwide. The low evidence base for our recommendations reflects a shortage of research specific to less resourced countries and serves as an impetus for further inquiry towards optimizing care for children with JIA around the world.
