RESUMO
Juvenile Idiopathic Arthritis (JIA) is the most common chronic rheumatic disease in childhood, and is associated with uveitis in up to 20-25% of cases. Typically, the uveitis is chronic, asymptomatic, non-granulomatous and anterior. For this reason, screening for uveitis is recommended to identify uveitis early and allow treatment to prevent sight-threatening complications. The management of JIA associated uveitis requires a multidisciplinary approach and a close collaboration between paediatric rheumatologist and ophthalmologist. Starting the appropriate treatment to control uveitis activity and prevent ocular complications is crucial. Current international recommendations advise a step-wise approach, starting with methotrexate and moving on to adalimumab if methotrexate alone is not sufficient to control the disease. If the uveitis remains active despite standard treatment other therapeutic options may be considered including anti-IL6 or other anti-TNF agents such as infliximab, although the evidence for these agents is limited.
RESUMO
PURPOSE: To document the long-term visual outcomes in patients with Blau syndrome. METHODS: A retrospective institutional cohort study was conducted, and 13 patients with genetically confirmed Blau syndrome were included. Demographic and clinical data were collected from standardised medical charts. Baseline was defined as the first detected uveitis and data were recorded onwards at intervals of 1, 3, 5, 10, 15 and 20 years. RESULTS: Anterior uveitis was the most common classification at baseline (57.1%). Among patients with documented uveitis lasting 10 years or more, all of them developed panuveitis. Median logMAR visual acuity at baseline was 0 (range -0.5; 0.7), 0.19 (range 0; 1.5) at year 5, and 0.7 (range 0.1 - no perception of light) at year 20, as recorded in 13, 16, and 10 eyes, respectively. All patients received treatment with topical and oral steroids, and multiple systemic immunosuppressants including biologics. Disease control, defined as having cells <1+ in both eyes and using topical steroid eye drops less than twice daily, was achieved in 14.3% to 37.5% of patients at the different time points. Cataract surgery was performed in 12 eyes of 8 patients, 3 eyes of 3 patients necessitated glaucoma surgery, and 4 eyes of 4 patients required surgery for retinal detachment. CONCLUSION: Uveitis associated with Blau syndrome commonly leads to severe, chronic panuveitis, requiring long-term systemic immunosuppression. Early diagnosis and timely initiation of biologics may prevent significant visual impairment.
RESUMO
IMPORTANCE: Idiopathic uveitis makes up around 50% of non-infectious uveitis but the clinical characteristics in children are poorly understood. OBJECTIVE: To report the demographic, clinical characteristics, and outcomes of children with idiopathic non-infectious uveitis (iNIU) in a multicentric retrospective study. RESULTS: There were 126 (61 female) children with iNIU. The median age at diagnosis was 9.3 years (3-16 years) . Uveitis was bilateral in 106 patients and anterior in 68.At onset,impaired visual acuity and blindness in the worse eye were reported, in 24.4% and 15.1% patients but at 3 years of follow-up, there was a significant improvement in visual acuity (mean 0.11 SD ±0.50 vs 0.42 SD ± 0.59 p < .001). CONCLUSIONS AND RELEVANCE: There is a high rate of visual impairment at presentation in children with idiopathic uveitis. The majority of patients have a significant improvement in vision, but 1 in 6 had impaired vision or blindness in their worse eye at 3 years.
This is a large retrospective study of children with chronic idiopathic uveitis,There is a high rate of visual impairment at presentation in children with idiopathic uveitis. Although visual acuity improves during follow-up, one in six still had impaired vision or blindness in their worse eye at 3 years.At 3 years, more than half of patients were on immunosuppression and one-third were on a biologic agent.

OBJECTIVES: GCA is systemic vasculitis manifesting as cranial, ocular or large vessel vasculitis. A prior qualitative study developed 40 candidate items to assess the impact of GCA on health-related quality of life (HRQoL). This study aimed to determine final scale structure and measurement properties of the GCA patient reported outcome (GCA-PRO) measure. METHODS: Cross-sectional study included UK patients with clinician-confirmed GCA. They completed 40 candidate items for the GCA-PRO at times 1 and 2 (3 days apart), EQ-5D-5L, ICECAP-A, CAT-PROM5 and self-report of disease activity. Rasch and exploratory factor analyses informed item reduction and established structural validity, reliability and unidimensionality of the final GCA-PRO. Evidence of validity was also established with hypothesis testing (GCA-PRO vs other PRO scores, and between participants with 'active disease' vs those 'in remission') and test-retest reliability. RESULTS: The study population consisted of 428 patients: mean (s.d.) age 74.2 (7.2), 285 (67%) female; 327 (76%) cranial GCA, 114 (26.6%) large vessel vasculitis and 142 (33.2%) ocular involvement. Rasch analysis eliminated 10 candidate GCA items and informed restructuring of response categories into four-point Likert scales. Factor analysis confirmed four domains: acute symptoms (eight items), activities of daily living (seven items), psychological (seven items) and participation (eight items). The overall scale had adequate Rasch model fit (χ2 = 25.219, degrees of freedom = 24, P = 0.394). Convergent validity with EQ5D-5L, ICECAP-A and Cat-PROM5 was confirmed through hypothesis testing. Internal consistency and test-retest reliability were excellent. CONCLUSION: The final GCA-PRO is a 30-item, four-domain scale with robust evidence of validity and reliability in measuring HRQoL in people with GCA.

ABSTRACT PURPOSE: To highlight similarities between the cross-sectional retinal lesion appearance in a patient with punctate inner choroidopathy (PIC), Ebola virus disease (EVD) retinopathy and the von Szily mouse model of herpes simplex virus type 1 (HSV) retinopathy. METHODS: Case report and cross-sectional retinal lesion comparison. RESULTS: Whilst phenotypically different on colour imaging, a near-identical lesion appearance on optical coherence tomography, characterised by a focal photoreceptor loss and distinctive V-shaped collapse of the overlying retinal layers, was observed in both PIC and EVD retinopathy. This mirrored the early histological appearance of the neuronally transmitted HSV retinopathy in a mouse model. CONCLUSIONS: Given the occurrence of this phenotypic appearance has been demonstrated in an animal model where the viral pathophysiological mechanism is known, together with its observation in EVD retinopathy with a shared, hypothesised neurotropic retinal pathogenesis, the potential of a common pathophysiology accounting for the appearance in PIC lesions is a possibility which may provide a potential avenue for future research.

OBJECTIVE: To explore patient perceptions of physical activity in giant cell arteritis (GCA). METHODS: This was a multinational qualitative study, analyzing interview data collected from participants from the UK (n = 25) and Australia (n = 11) with a definitive diagnosis of GCA from imaging or biopsy. Interview transcripts were analyzed using thematic analysis to identify themes related to physical activity. This was secondary analysis of data collected to explore health-related quality of life in people with GCA. RESULTS: A total of 108 individual codes pertaining to physical activity were identified. These were grouped into 2 overarching themes: barriers to and facilitators of physical activity, each with 4 subthemes. Barriers were categorized into physical symptoms (including visual loss, fatigue, weakness, pain, and stiffness), perceptions of personal capability (including poor stamina, confidence, and mobility), negative perceptions of physical activity, and negative consequences. Facilitators of physical activity were categorized into external facilitators (including motivation from health care professionals and support groups), access to appropriate facilities, personal strategies (including pacing and goal-setting), and personal facilitators (including internal motivation to improve symptoms, and positive reinforcement). CONCLUSION: A range of barriers and facilitators to physical activity were identified in relation to GCA. Future work could include development of an intervention to support physical activity in patients with GCA; ideally this intervention should be underpinned by an appropriate behavioral change framework and codesigned with patients.

BACKGROUND: Juvenile idiopathic arthritis (JIA) is the most common pediatric rheumatic disease and the most common systemic disorder associated with uveitis in childhood. Uveitis is more common in JIA patients who are antinuclear antibody (ANA)-positive, have an early-onset disease, and have oligoarticular arthritis. JIA-associated uveitis (JIA-uveitis) is typically anterior, chronic, bilateral, nongranulomatous, and asymptomatic. Visual outcomes in JIA-uveitis have improved with current screening and treatment options; however, many patients fail to respond or do not achieve long-lasting remission. Baricitinib, an oral selective Janus kinase (JAK)1 and 2 inhibitor, may impact key cytokines implicated in the pathogenesis of JIA-uveitis or ANA-positive uveitis, representing a potential novel treatment option for disease management. METHODS: The multicenter, phase 3 trial will be conducted using an open-label Bayesian design. The study will enroll at least 20 and up to 40 patients aged 2 to <18 years with active JIA-uveitis or chronic ANA-positive uveitis without systemic features. At least 20 patients who have had an inadequate response or intolerance to methotrexate (MTX-IR), but not biologic disease-modifying antirheumatic drugs (bDMARDs), will be randomized (1:1) to open-label baricitinib or adalimumab. Approximately 20 additional patients who are MTX-IR or bDMARD inadequate responders will receive baricitinib treatment. Patients will be treated with once daily oral baricitinib at a fixed dose by age group (4 mg for patients aged ≥6 to <18 years and 2 mg for patients <6 years) or adalimumab (20 mg for patients weighing <30 kg and 40 mg for patients ≥30 kg) as a subcutaneous injection every 2 weeks. Treatment with stable background conventional synthetic DMARDs, low-dose corticosteroids, and/or nonsteroidal anti-inflammatory drugs is allowed. The primary endpoint is the proportion of patients with response at week 24. Patients may continue treatment for up to 5 years. DISCUSSION: This is the first pediatric clinical trial to assess the clinical effectiveness and safety of a JAK inhibitor in JIA-uveitis or chronic ANA-positive uveitis. A novel Bayesian design is used to assess the efficacy of baricitinib, including an adalimumab reference arm, in this small patient population with unmet medical need.

OBJECTIVES: GCA is a large vessel vasculitis (LVV) presenting with headache, jaw claudication, musculoskeletal and visual involvement. Current treatment is glucocorticoids and anti-IL-6 tocilizumab in refractory disease. The objective of this study was to explore the impact of GCA and its treatment on people's health-related quality of life (HRQoL), to inform the development of a disease-specific patient-reported outcome measure (PROM) for use in clinical trials and practice. METHODS: Participants from the UK and Australia, with biopsy- or imaging-confirmed GCA, were interviewed to identify salient aspects of HRQoL in relation to GCA and its treatment. Purposive sampling included a range of demographic and disease features (cranial, LVV-GCA and visual involvement). Inductive analysis identified individual themes of importance, then domains. Candidate questionnaire items were developed from the individual themes, refined by piloting, cognitive interviews and a linguistic translatability assessment. RESULTS: Thirty-six interviews were conducted to saturation with participants with GCA from the UK (25) and Australia (11). Mean age was 74 years, 23 (63.9%) were female, 13 (36.1%) had visual loss and 5 (13.9%) had LVV-GCA. Thirty-nine individual themes within five domains were identified: physical symptoms; activity of daily living and function; participation; psychological impact; and impact on sense of self and perception of health. Sixty-nine candidate items were developed from individual themes; piloting and refinement resulted in a 40-item draft questionnaire. CONCLUSION: This international qualitative study underpins the development of candidate items for a disease-specific PROM for GCA. The draft questionnaire is now ready for psychometric testing.

BACKGROUND: Uveitis associated with juvenile idiopathic arthritis is a cause of major ocular morbidity. A substantial proportion of children are refractory to systemic methotrexate and TNF inhibitors. Our aim was to study the safety and efficacy of tocilizumab in children with juvenile idiopathic arthritis-associated uveitis refractory to both methotrexate and TNF inhibitors. METHODS: This multicentre, single-arm, phase 2 trial was done following a Simon's two-stage design at seven tertiary hospital sites in the UK. Patients aged 2-18 years with active juvenile idiopathic arthritis-associated uveitis were eligible. All patients had been on a stable dose of methotrexate for at least 12 weeks and had not responded to treatment with a TNF inhibitor. Patients weighing 30 kg or more were treated with 162 mg subcutaneous tocilizumab every 2 weeks for 24 weeks, and participants weighing less than 30 kg were treated with 162 mg every 3 weeks for 24 weeks. The primary outcome was treatment response defined as a two-step decrease, or decrease to zero, from baseline in the level of inflammation (anterior chamber cells) at week 12, per the standardisation of uveitis nomenclature criteria. A phase 3 trial would be justified if more than seven patients responded to treatment. An interim analysis was planned to assess whether the trial would be stopped for futility, with futility defined as two or fewer treatment responses among ten participants. Adverse events were collected up to 30 calendar days after treatment cessation. The primary analysis was done in the intention-to-treat population and the safety analysis was done in all patients who started the treatment. This trial is registered with the International Standard Randomised Controlled Trial Number registry (ISRCTN95363507) and EU Clinical Trials Register (EudraCT 2015-001323-23). FINDINGS: 22 participants were enrolled to the trial between Dec 3, 2015, and March 9, 2018, and 21 participants received treatment. One participant was found to be ineligible immediately after enrolment and was therefore withdrawn. Seven of 21 (median unbiased estimate of proportion 34% [95% CI 25-57]) responded to treatment (p=0·11). Safety results were consistent with the known safety profile of tocilizumab. INTERPRETATION: The primary endpoint was not met, and thus the results do not support a phase 3 trial of tocilizumab in patients with juvenile idiopathic arthritis-associated uveitis. Importantly, data on the use of tocilizumab in clinical practice is now captured in national registries. Despite this trial not meeting the threshold required to justify a larger phase 3 trial, several patients responded to treatment; as such, tocilzumab might still be a therapeutic option in some children with uveitis refractory to anti-TNF drugs, given the absence of other treatment options.

RESUMO
BACKGROUND: Biologic medications have dramatically enhanced the treatment of many chronic paediatric inflammatory conditions. Their high cost is a factor that prohibits their broader use. Cheaper generic versions, or biosimilars, are increasingly being used. Healthcare services are switching some patients over to biosimilars for economic reasons, known as 'non-medical switching'. Some patients unsuccessfully switch due to perceived decreases in efficacy or non-specific drug effects. The implications of failed switching include exhaustion of therapeutic options, unnecessary exposure to other medications, increased healthcare utilisation, worse patient outcomes and higher overall healthcare costs. Patient perceptions almost certainly play a role in these 'failed switches'. METHODS: A thematic analysis was performed to better understand patient and parent perceptions on non-medical biosimilar switching. The study was conducted in accordance with the Consolidated Criteria for Reporting Qualitative Research recommendations. Patients with juvenile idiopathic arthritis currently taking adalimumab were included. RESULTS: Nine families were interviewed just prior to a hospital trust-wide non-medical switch to an adalimumab biosimilar. Several common themes were identified. The most frequent concerns were regarding practical aspects of the switch including the medication administration device type; the colour of the medication and administration device; and whether the injections would sting more. The relative safety and efficacy of the biosimilar was raised although most families felt that there would be no significant difference. Anxieties about the switch were largely placated by reassurances from the medical team. CONCLUSIONS: We derived recommendations based on existing adult literature and the observations from our study to optimise the benefits from non-medical biosimilar switching.

PURPOSE: To determine longer-term outcomes of participants enrolled from a single center in the SYCAMORE trial, a randomized placebo-controlled trial of adalimumab vs placebo in children with juvenile idiopathic arthritis-associated uveitis (JIA-U) uncontrolled on methotrexate. DESIGN: Retrospective interventional case series. METHODS: Medical records of all 28 SYCAMORE participants recruited at the Bristol Eye Hospital were reviewed at approximately 3-monthly intervals up to 5 years from the trial randomization date. Uveitis activity, treatment course, visual outcomes, ocular complications, and adverse events were recorded. Data are presented using summary statistics. RESULTS: Following withdrawal of the investigational medicinal product (IMP), 25 of the 28 participants were started on adalimumab for active JIA-U. Of the 12 participants in the active treatment arm of the SYCAMORE study, 11 (92%) were restarted on adalimumab after withdrawal of the IMP for active JIA-U (median time to flare 188 days [range 42-413 days). Two participants stopped adalimumab for uncontrolled JIA-U. One participant had a reduction in vision to 0.3 owing to cataract. Mean visual acuity for the remaining 27 participants was -0.04 (right eye) and -0.05 (left eye). CONCLUSIONS: Drug-induced remission of JIA-U did not persist when adalimumab was withdrawn after 1-2 years of treatment. Adalimumab was well tolerated and visual acuity outcomes were excellent.

BACKGROUND: There is a paucity of data on the ocular outcomes in paediatric non-infectious uveitis since the introduction of the biologic agents. The purpose of this study was to outline the clinical characteristics of children with non-infectious uveitis and determine the visual outcomes and ocular complication rates in the modern era. METHODS: Children with non-infectious uveitis from January 2011 to December 2015 were identified. Data was collected at baseline, 1, 3, 5, and 10 years post diagnosis. The incidence rates of visual impairment, structural ocular complications and surgical intervention were calculated. Using logistic regression the association between various baseline characteristics and later visual impairment was investigated. RESULTS: Of the 166 children, 60.2% (n = 100) had a systemic disease association. 72.9% (n = 121) children received methotrexate, 58 children progressed to a biologic. The incidence rates of visual acuity loss to > 0.3 LogMAR (6/12) and to ≥1.0 LogMAR (6/60) were 0.05/Eye Year (EY) and 0.01/EY, respectively. Visual outcomes in the Juvenile Idiopathic Arthritis associated Uveitis (JIA-U) and Idiopathic Uveitis cohorts were not statistically significant. Of the 293 affected eyes, posterior synechiae was the predominant complication on presentation, while cataract had the highest incidence rate (0.05/EY). On direct comparison, children with JIA-U were statistically significantly more likely to develop glaucoma while children with Idiopathic Uveitis were statistically significantly more likely to develop macular oedema. CONCLUSION: One third of children received a biological therapy, reflecting increasing utilisation and importance of biological agents in the management of inflammatory conditions. Rates of visual impairment and ocular complications are an improvement on previously published data.

Acute macular neuroretinopathy (AMN) is a rare disease, the etiology of which remains unclear. An ischemic event at the level of the deep capillary plexus has been proposed. The authors present three cases of AMN in the context of active systemic Behçet's disease, with the support of multimodal imaging. All patients were known to have Behçet's disease before the diagnosis of AMN. AMN was confirmed in all three cases on spectral domain optical coherence tomography (SD-OCT), near infrared reflectance and OCT angiography. Behçet's disease is known to be a prothrombotic disease. The presentation of AMN in this context supports the presumed ischemic etiology of AMN. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:634-638.].

OBJECTIVE: To identify biomarkers of articular and ocular disease activity in patients with Blau syndrome (BS). METHODS: Multiplex plasma protein arrays were performed in five BS patients and eight normal healthy volunteers (NHVs). Plasma S100A12 and S100A8/9 were subsequently measured by ELISA at baseline and 1-year follow-up in all patients from a prospective multicentre cohort study. CRP was measured using Meso Scale Discovery immunoassay. Active joint counts, standardization uveitis nomenclature for anterior uveitis cells and vitreous haze by Nussenblatt scale were the clinical parameters. RESULTS: Multiplex Luminex arrays identified S100A12 as the most significantly elevated protein in five selected BS vs eight NHVs and this was confirmed by ELISA on additional samples from the same five BS patients. In the patient cohort, S100A12 (n = 39) and S100A8/9 (n = 33) were significantly higher compared with NHVs (n = 44 for S100A12, n = 40 for S100A8/9) (P = 0.0000004 and P = 0.0003, respectively). Positive correlations between active joint counts and S100 levels were significant for S100A12 (P = 0.0008) and S100A8/9 (P = 0.015). CRP levels did not correlate with active joint count. Subgroup analysis showed significant association of S100 proteins with active arthritis (S100A12 P = 0.01, S100A8/9 P = 0.008). Active uveitis was not associated with increased S100 levels. CONCLUSION: S100 proteins are biomarkers of articular disease activity in BS and potential outcome measures in future clinical trials. As secreted neutrophil and macrophage products, S100 proteins may reflect the burden of granulomatous tissue in BS.

BACKGROUND: Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children. Children with JIA are at risk of intraocular inflammation (uveitis). In the initial stages of mild-moderate inflammation uveitis is asymptomatic. Most children with mild-moderate uveitis are managed on topical steroid drops with or without systemic methotrexate (MTX). When children with moderate-severe uveitis are refractory to MTX, monoclonal anti-tumour necrosis factor agents have been trialled, interim analysis data showed positive results. However, several children with severe recalcitrant disease or non-responsive to anti-tumour necrosis factor agents remain and are at greater risk of significant ocular complications and visual loss. Further evidence of alternative therapies is needed with evidence of a potential role of anti-interleukin-6 agents in the management of severe refractory uveitis. METHODS: The trial will be conducted following a two-stage Simon design. The trial will register at least 22 patients aged 2 to 18 years with active JIA-associated uveitis, who have taken MTX for at least 12 weeks and have failed an anti-TNF agent. It will take place in 7 centres across the UK. All participants will be treated for 6 months, with follow up of 9 months from registration. Participants will receive a stable dose of MTX and those weighing ≥30 kg will be dosed with 162 mg of Tocilizumab every 2 weeks and participants weighing < 30 kg dosed with 162 mg of Tocilizumab every 3 weeks. Primary outcome is treatment response at 12 weeks. Adverse events will be collected up to 30 calendar days following treatment cessation. DISCUSSION: This is a novel adaptive design study of subcutaneous IL-6 inhibition in anti-TNF refractory JIA associated uveitis which will be able to determine if further research should be conducted. This is the first trial to look at ophthalmology outcomes in the efficacy of Tocilizumab in uveitis.This is the first paediatric clinical trial to assess the clinical effectiveness and safety of tocilizumab with MTX in JIA associated uveitis. TRIALS REGISTRATION: The Trial is registered on the ISRCTN registry (ISRCTN95363507) on the 10/06/2015 and EU Clinical Trials Register on the 03/07/2015 (EudraCT Number: 2015-001323-23).
RESUMO
PURPOSE: To describe the phenotype of the uveitis that accompanies juvenile psoriatic arthritis or psoriasis. DESIGN: Observational case series. METHODS: Setting: Two university-based referral clinics: 1 in England, 1 in the United States. STUDY POPULATION: Five children with uveitis and psoriatic arthritis and 1 with uveitis and psoriasis Observational Procedure: Retrospective chart review. MAIN OUTCOME MEASURES: Demographics of subjects such as age and sex; description of ocular and joint disease; surgical and other complications; medical treatment. RESULTS: Five of the 6 children in this series had the onset of disease at or before age 6 (P = .0008 compared to expected age of onset for psoriatic arthritis in childhood). All children in this series had an inadequate response to topical corticosteroids. Most of the children were treated with systemic corticosteroids for many months, yet all of them went on to require methotrexate. Therapy with systemic methotrexate did not suffice, as all the patients also required some form of biologic therapy. Five of 6 had surgeries such as vitrectomy, cataract extraction, or a procedure for glaucoma control. CONCLUSIONS: The observations suggest that the uveitis that accompanies juvenile psoriatic arthritis might be a distinct disease that is particularly severe when its onset affects children aged 6 years or younger.

PURPOSE: Provide baseline and preliminary follow-up results in a 5-year longitudinal study of Blau syndrome. DESIGN: Multicenter, prospective interventional case series. METHODS: Baseline data from 50 patients from 25 centers worldwide, and follow-up data for patients followed 1, 2, or 3 years at the end of study enrollment. Ophthalmic data were collected at baseline and yearly visits by means of a standardized collection form. RESULTS: Median age at onset of eye disease was 60 months and duration of eye disease at baseline 145 months. At baseline 38 patients (78%) had uveitis, which was bilateral in 37 (97%). Eight patients (21%) had moderate to severe visual impairment. Panuveitis was found in 38 eyes (51%), with characteristic multifocal choroidal infiltrates in 29 eyes (39%). Optic disc pallor in 9 eyes (12%) and peripapillary nodules in 9 eyes (12%) were the commonest signs of optic nerve involvement. Active anterior chamber inflammation was noted in 30 eyes (40%) at baseline and in 16 (34%), 17 (57%), and 11 (61%) eyes at 1, 2, and 3 years, respectively. Panuveitis was associated with longer disease duration. At baseline, 56 eyes (75%) were on topical corticosteroids. Twenty-six patients (68%) received a combination of systemic corticosteroids and immunomodulatory therapy. CONCLUSIONS: Blau uveitis is characterized by progressive panuveitis with multifocal choroiditis, resulting in severe ocular morbidity despite continuous systemic and local immunomodulatory therapy. The frequency and severity of Blau uveitis highlight the need for close ophthalmologic surveillance as well as a search for more effective therapies.
