Risk factors for ocular complications and poor visual acuity at presentation among patients with uveitis associated with juvenile idiopathic arthritis

Sociodemographic and Visual Outcomes of Juvenile Idiopathic Arthritis Uveitis: IRIS® Registry Study

Purpose

Understanding sociodemographic factors associated with poor visual outcomes in children with juvenile idiopathic arthritis-associated uveitis may help inform practice patterns.

Patients and Methods

Retrospective cohort study on patients <18 years old who were diagnosed with both juvenile idiopathic arthritis and uveitis based on International Classification of Diseases tenth edition codes in the Intelligent Research in Sight Registry through December 2020. Surgical history was extracted using current procedural terminology codes. The primary outcome was incidence of blindness (20/200 or worse) in at least one eye in association with sociodemographic factors. Secondary outcomes included cataract and glaucoma surgery following uveitis diagnosis. Hazard ratios were calculated using multivariable-adjusted Cox proportional hazards models.

Results

Median age of juvenile idiopathic arthritis-associated uveitis diagnosis was 11 (Interquartile Range: 8 to 15). In the Cox models adjusting for sociodemographic and insurance factors, the hazard ratios of best corrected visual acuity 20/200 or worse were higher in males compared to females (HR 2.15; 95% CI: 1.45-3.18), in Black or African American patients compared to White patients (2.54; 1.44-4.48), and in Medicaid-insured patients compared to commercially-insured patients (2.23; 1.48-3.37).

Conclusion

Sociodemographic factors and insurance coverage were associated with varying levels of risk for poor visual outcomes in children with juvenile idiopathic arthritis-associated uveitis.

Taiwan ocular inflammation society consensus recommendations for the management of juvenile idiopathic arthritis-associated uveitis

We presented the development of a consensus guideline for managing juvenile idiopathic arthritis-associated uveitis (JIAU) in Taiwan, considering regional differences in manifestation and epidemiology. The Taiwan Ocular Inflammation Society (TOIS) committee formulated this guideline using a modified Delphi approach with two panel meetings. Recommendations were based on a comprehensive evidence-based literature review and expert clinical experiences, and were graded according to the Oxford Centre for Evidence-Based Medicine's "Levels of Evidence" guideline (March 2009). The TOIS consensus guideline consists of 10 recommendations in four categories: screening and diagnosis, treatment, complications, and monitoring, covering a total of 27 items. These recommendations received over 75% agreement from the panelists. Early diagnosis and a coordinated referral system between ophthalmologists and pediatric rheumatologists are crucial to prevent irreversible visual impairment in children with JIAU. However, achieving a balance between disease activity and medication use remains a key challenge in JIAU management, necessitating further clinical studies.

Epidemiology, Treatment, and Outcomes of Juvenile Idiopathic Arthritis-Associated Uveitis: A Multi-Institutional Study in Taiwan

PURPOSE

To assess the epidemiology, treatment, and outcomes of juvenile idiopathic arthritis (JIA)-associated uveitis (JIA-U) in Taiwan.

METHODS

Retrospective, multicenter database.

RESULTS

Totally, 44 (6.1%) of the 722 JIA patients had uveitis. The mean ages of JIA and JIA-U diagnosis were 10.7 and 11.1 years, respectively. JIA-U patients had more antinuclear antibody presence. Among JIA-U patients, 25 (56.8%) were male, 11 (25.0%) experienced any ocular complication, and 8 (18.2%) received ocular surgery. Inactivity lasting ≥6 months was achieved in 17 (38.6%) patients; however, 11 (25.0%) of those experienced reactivation with a mean of 624.7 days after achieving inactivity. Female had more ocular complications and surgeries.

CONCLUSION

Late age at JIA-U diagnosis and male predominance were distinctive in Taiwan. For patients with inactivity lasting ≥ 6 months was achieved, they still required close follow-up due to the high reactivation rate within 2 years. Female had poorer ocular outcomes.

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.

Risk Factors for Ocular Complications and Visual Loss in Patients with Juvenile Idiopathic Arthritis-associated Uveitis at a Turkish Tertiary Ophthalmology and Pediatric Rheumatology Referral Center

PURPOSE

To investigate the rates of ocular complications and visual loss and their risk factors in patients with juvenile idiopathic arthritis (JIA) -associated uveitis.

METHODS

Medical records of 51 patients were reviewed.

RESULTS

The incidence of visual loss to the 20/50 or worse was found to be 0026/ eye-year (EY) in the present study. Cataract and ocular hypertension occurred during the follow-up period and were significantly associated with visual acuity loss to 20/50 or worse (p = .008, HR 11.932, 95% CI 1.915-74.355; p = .03, HR 7.323, 95% CI 1.216-44.110, respectively). Anti-TNF therapy was initiated in 88.2% of our cases and 93.3% of them achieved uveitis inactivity.

CONCLUSION

The risk of vision loss is higher in patients with JIA-associated uveitis who had complications at presentation. We attribute the lower complication rates and better visual outcomes in our study to the early and frequent use of biologic agents.

Encouraging visual outcomes in children with idiopathic and JIA associated uveitis: a population-based study

BACKGROUND

Pediatric uveitis is typically asymptomatic and may become chronic affecting ocular structures and vision. We evaluated visual outcomes, clinical features, medication, and uveitis activity in children with either idiopathic uveitis (idio-U) or juvenile idiopathic arthritis associated uveitis (JIA-U).

METHODS

A longitudinal, population-based cohort study of children with uveitis in 2008-2017. The data included parameters for age, gender, age at diagnosis, laterality, chronicity, anatomical distribution, etiology, systemic association, uveitis activity, medication, and visual outcomes.

RESULTS

A total of 119 patients aged < 16 years with uveitis were included. Uveitis was idio-U in 23% and associated with JIA in 77% of cases. 37% of the patients in the idio-U group and 65% in the JIA-U were girls (p = 0.014). The mean age at first uveitis was 10.0 (SD 3.4) years in idio-U and 5.5 (SD 3.3) years in JIA-U (p < 0.001). Anterior location of uveitis was noted in 74% in idio-U and 99% in JIA-U (p < 0.001). Mostly, uveitis was chronic (59% in idio-U and 75% in JIA-U) and bilateral (56% in idio-U and 64% in JIA-U). Topical corticosteroids were initially used by 89% and 100%, systemic corticosteroids by 30% and 27% in some extent during the follow-up, disease-modifying antirheumatic drugs (DMARDs) by 33% and 85% (p < 0.001) of the patients in idio-U and JIA-U, respectively. Biologic disease-modifying antirheumatic drugs (bDMARDs) were more common in JIA-U (55% vs. 15% in idio-U, respectively, p < 0.001). Most patients had normal visual acuity (Snellen > 0.8, [6/7.5]) in the affected eye and bilaterally in 85% idio-U and 70% JIA-U. Only 5 patients (4%) had visual impairment in one, but none in both eyes. Uveitis activity by SUN classification was 0 + in 81% and 72%, 0.5 + in 19% and 25%, and 1 + in 0% and 3% in the idio-U and JIA-U, respectively.

CONCLUSIONS

Children with uveitis have good visual acuity and a low rate for visual impairment. In addition, modern treatment with DMARDs and bDMARDs seems to save vision.

Outcomes of cataract surgery in children who present with cataract at uveitis diagnosis

PURPOSE

To describe the clinical and demographic characteristics of patients presenting with cataract at uveitis diagnosis treated at a single institution between 2005 and 2019 and to analyze postoperative outcomes following cataract surgery.

METHODS

We retrospectively reviewed the medical records of children (<18 years of age) diagnosed with cataract at their initial uveitis presentation who subsequently underwent cataract extraction. Outcome measures were best-corrected visual acuity, number of uveitis flare-ups (cells ≥1+), and postoperative complications.

RESULTS

A total of 14 children (17 eyes) were included. Mean patient age was 7.2 ± 3.9 years. Methotrexate was initiated preoperatively in 11 patients; adalimumab, in 3. Primary intraocular lens was implanted in 4 eyes. Best-corrected visual acuity improved from a mean of 0.90 ± 0.40 logMAR preoperatively to 0.50 ± 0.35 logMAR at 1 year and 0.57 ± 0.40 logMAR at mean of 6.3 ± 3.4 years postoperatively. Four eyes (24%) had a single episode of uveitis flare-up during the first postoperative year. Macular and/or disk edema was discovered in 6 eyes following cataract removal. Only 3 eyes (18%) had ocular hypertension in the first year, but glaucoma developed in subsequent years in 7 eyes (41%), 5 of which required surgery.

CONCLUSIONS

In our study cohort, surgery for preexisting cataract at uveitis diagnosis resulted in improved visual acuity. Postoperative uveitis flare-ups were relatively uncommon, occurring in 4 of 17 eyes. Glaucoma was the main long-term complication.

Paediatric anterior uveitis management in the USA: a single-centre, 10-year retrospective chart review exploring the efficacy and safety of systemic immunomodulatory therapy

OBJECTIVE

To evaluate the efficacy of immunomodulatory therapy (IMT) in paediatric anterior uveitis.

METHODS

Chart review of all patients ≤ 18 years treated for anterior uveitis using a stepladder approach during a 10-year period. The type and duration of IMT were noted. The data were analysed depending on chronicity, aetiology, and type of IMT using appropriate statistical tests. The outcome measures included ocular complications, the need for surgical intervention, and visual outcomes.

RESULTS

One hundred and thirty-four patients (191 eyes) were analyzed. The median age at diagnosis was 7 years (interquartile range (IQR): 7.5 years). The median follow-up was 4 years (IQR: 6 years). The most common causes of anterior uveitis were Juvenile idiopathic arthritis (64 patients, 47.8%) and undifferentiated (33 patients, 24.6%). All patients were started on topical steroids and cycloplegics. 94 (70%) patients required IMT. 92 (68.6%) were started on Methotrexate as the first agent, of which 21 (22%) were switched to a different agent owing to side effects. Biologic agent was added in 55 (41%) patients. 21 (16%) required switch to a second biologic agent, 5 (3.7%) to third, and 1 (0.8%) to fourth biologic agent. At the last exam, 11 (8%) had persistent inflammation. 55 (41%) had ocular complications, and 113 (84%) had a best corrected visual acuity ≥ 20/40.

CONCLUSION

Early introduction of IMT and switch to different agents may be required to control anterior uveitis and reduce the complications in children. IMT is safe and effective in treating paediatric anterior uveitis.

The efficacy of anti-TNF-α agents in the treatment of juvenile idiopathic arthritis-associated uveitis in a pediatric cohort

Purpose

Biologic therapy has shown promising control in children with often intractable juvenile idiopathic arthritis (JIA)-associated uveitis (JIA-U).

Methods

This is a retrospective cohort study of 35 eyes of 35 children who received biologics for JIA-U. Pretreatment and posttreatment data (at 3, 6, 9, 12, 18, 24, and >24 months) were analyzed to determine functional success (stable/improved visual acuity), quiescence success (≤0.5 cells in the anterior chamber), complete steroid success (termination of systemic, periocular therapy and decreased topical drops to ≤2/day) or systemic steroid success (termination of systemic steroids only), and complete success (all of the above).

Results

This study included 35 eyes up to 12 months and 21 eyes beyond 24 months. Steroid-sparing, functional, and quiescence success showed a rate of success of 52.43%, 77%, and 91%, respectively, at 12 months and 66.67%, 85.7%, and 76.2%, respectively, beyond 24 months. Complete success was 34.29% at 12 months, peaking at 18 months (65.62%) and reached 57.14% beyond 24 months. In their final follow-up, the best corrected visual acuity (BCVA) remained the same in 45.71%, improved in 37.14%, and worsened in 17.14% children.

Conclusion

Biologic therapy is effective in JIA-U, especially in termination of systemic steroids, stabilization of vision, and maintaining quiescence.

Assessment of Cardiovascular Risk Factors in Patients with Juvenile Idiopathic Arthritis

Introduction: The aim of this study was to assess the exposure to cardiovascular disease (CVD) risk factors in patients with juvenile idiopathic arthritis (JIA). Intima–media complex thickness (IMT), selected metabolic parameters and health behaviors were assessed in the course of the study. Methods: The study included study group, which consisted of 45 patients with JIA and 37 healthy age- and sex-matched children in the control group. Analyses in both groups included anthropometric parameters, laboratory tests, IMT and a questionnaire on exposure to modifiable CVD risk factors. Results: The study confirmed that CVD risk factors were present in both groups of patients. Significantly more children with JIA had abnormal BMI (p = 0.006) compared to the control group. Children in the study group were more likely to consume fruit regularly (p = 0.021) and less likely to consume fast food (p = 0.011) and sweetened beverages (p = 0.042) than children in the control group. Only 1 patient with JIA met criteria for ideal cardiovascular health. Dietary habits were not associated with IMT values, BMI, presence of joint pain or biochemical parameters in the study group. Conclusions: Patients with JIA are exposed to cardiovascular risk factors equally to their healthy peers. Ideal cardiovascular health should be pursued in the pediatric population with particular attention paid to patients with chronic diseases (i.e., JIA). The application of carotid artery IMT measurement in the assessment of CVD risk requires studies on a larger group of patients.

Comparing the Efficacy of Intravitreal Dexamethasone and Time-displaced Fluocinolone Acetonide on Central Retinal Thickness in Patients with Uveitis

BACKGROUND

To compare the efficacy of intravitreally administered dexamethasone (Dex) and subsequent time-displaced fluocinolone acetonide (FA) on central subfield thickness (CST) in eyes with noninfectious uveitis.

METHODS

Retrospective analysis of twenty-three eyes (18 patients) subsequently receiving intravitreal Dex and FA implants. The main outcome measures were CST, best-corrected visual acuity (BCVA), intraocular pressure (IOP), and status of inflammation.

RESULTS

CST (Dex: p < .0001; FA: p = .0008) and BCVA (Dex: p = .0009; FA: p = .0005) improved significantly with both implants. Significantly better effects were noted with Dex for absolute and relative CST reduction (p = .0089 and p = .0051, respectively). Final BCVA did not differ between groups (p = .1893). Dex significantly increased IOP, whereas FA did not. One eye was actively inflamed after Dex and FA injection at follow-up (inflamed eyes before injection: [Dex: 2; FA: 6]).

CONCLUSION

Both implants significantly reduced CST and induced a significant gain in visual acuity. Dex might be more effective in reducing CST.

Alternative Biologic Therapy in Children Failing Conventional TNFα Inhibitors for Refractory, Noninfectious, Chronic Anterior Uveitis

PURPOSE

A significant number of children with noninfectious, chronic anterior uveitis (CAU) fail to respond to conventional therapy; however, successful alternative biologic treatments (ABT) have not been well described. This study aims to review the clinical and treatment characteristics of children with CAU who require ABT.

DESIGN

Retrospective, nonrandomized clinical study.

METHODS

Setting: Tertiary center.

STUDY POPULATION

Children with noninfectious CAU.

OBSERVATION PROCEDURES

Clinical characteristics, uveitis course, complications, and treatment were compared among patients treated with methotrexate (MTX) monotherapy, conventional TNFα inhibitors (cTNFi), and ABT for >3 months.

MAIN OUTCOME MEASURE

Success of ABT (abatacept, tocilizumab, and/or golimumab) in children failing conventional treatment.

RESULTS

Of the 52 children with CAU, 75% had juvenile idiopathic arthritis. CAU was controlled in 15 children receiving MTX monotherapy, 28 receiving cTNFi, and 9 receiving ABT (n = 1, abatacept; n = 3, tocilizumab; n = 5, golimumab). Patients in the ABT group had a greater number of total ocular complications per person before ABT than those in the control groups (3.4 vs 0.7 [MTX], P < .001, and 1.5 [cTNFi], P < .001, respectively). In all 9 children on ABT, treatment led to control of CAU and topical glucocorticoids tapered to ≤2 drops/d with no new ocular complications.

CONCLUSIONS

In this study, alternative biologics (abatacept, golimumab, and tocilizumab) were useful for treating CAU in children who fail MTX and cTNFi therapy. Patients who were controlled on ABT had more disease activity, ocular complications, and anti-cTNFi neutralizing antibodies (before ABT) than those managed with conventional therapy. Larger studies are required to confirm these findings.

Improved clinical outcomes in patients with juvenile idiopathic arthritis associated uveitis in the last decade

PURPOSE

The purpose of the study was to analyse the development of ocular complications and visual prognosis in juvenile idiopathic arthritis associated uveitis (JIA-uveitis) compared to the previous decade in the light of new treatment guidelines.

METHODS

In this retrospective cohort, 143 patients with JIA-uveitis were stratified into two cohorts based on the year of diagnosis of uveitis, <2010 (n = 61) and ≥2010 (n = 82). Development of ocular complications and visual outcomes were analysed by univariate and multivariate methods. Treatment with systemic corticosteroids and immunomodifying medication (IMT) were documented.

RESULTS

In total, 109 and 133 affected eyes, respectively, for cohort 1 (<2010) and cohort 2 (≥2010) were included for analysis. In the multivariate analysis with correction for paired eyes, patients in cohort 1 were at higher risk for cataract surgery (p = 0.03) and secondary glaucoma (p = 5.15 × 10^-3 ). Also, the number of eyes that were legally blind and visually impaired at 5 years of follow-up was significantly higher in cohort 1 (7% versus 2% and 8% versus 0%, p = 0.01 respectively). The number of patients that started IMT was significantly higher in cohort 2 (57% versus 98%, p = 2.17 × 10^-6 ). In cohort 2, both methotrexate and anti-TNF-α therapy were prescribed earlier in the disease course (1.41 versus 0.05 years, p = 8.31 × 10^-6 and 6.07 versus 1.84 years, p = 5.14 × 10^-5 respectively).

CONCLUSIONS

The prognosis of JIA-uveitis has improved during the last decade. There is a reduction in the number of cataract surgeries and secondary glaucoma and fewer patients lose their vision parallel with earlier access to tertiary care and earlier introduction of IMT.

Ophthalmic sequelae and psychosocial impact in pediatric ebola survivors

Background

Ebola virus disease (EVD) outbreaks in West Africa (2013-2016) and the Democratic Republic of Congo (2018-2020) have resulted in thousands of EVD survivors who remain at-risk for survivor sequelae. While EVD survivorship has been broadly reported in adult populations, pediatric EVD survivors are under-represented. In this cross-sectional study, we investigated the prevalence of eye disease, health-related quality-of-life, vision-related quality-of-life, and the burden of mental illness among pediatric EVD survivors in Sierra Leone.

Methods

Twenty-three pediatric EVD survivors and 58 EVD close contacts were enrolled. Participants underwent a comprehensive ophthalmic examination and completed the following surveys: Pediatric Quality of Life Inventory Version 4.0, Effect of Youngsters Eyesight on Quality-of-Life, and the Revised Child Anxiety and Depression Scale.

Findings

A higher prevalence of uveitis was observed in EVD survivor eyes (10·8%) cohort compared to close contacts eyes (1·7%, p=0·03). Overall, 47·8% of EVD survivor eyes and 31·9% of close contact eyes presented with an eye disease at the time of our study (p=0·25). Individuals diagnosed with an ocular complication had poorer vision-related quality-of-life (p=0·02).

Interpretation

Both health related quality-of-life and vision-related quality-of-life were poor among EVD survivors and close contacts. The high prevalence of eye disease associated with reduced vision health, suggests that cross-disciplinary approaches are needed to address the unmet needs of EVD survivors.

Clinical course and outcome in pediatric idiopathic chronic anterior uveitis

PURPOSE

To examine the clinical course and outcome in children with idiopathic chronic anterior uveitis (iCAU) and compare the results with age-matched children with juvenile idiopathic arthritis-associated uveitis (JIA-U).

DESIGN

Retrospective cohort study.

METHODS

Data regarding ocular complications, visual acuity, and systemic treatment were retrospectively collected for two patient groups that were matched regarding age and year of uveitis diagnosis. Outcome was evaluated using survival analysis.

RESULTS

The iCAU and JIA-U groups included 48 patients with 83 affected eyes and 48 patients with 73 affected eyes, respectively. Multivariate analyses showed that iCAU was associated with a higher prevalence of posterior synechiae (adjusted hazard rate [aHR]: 3.63; P < 0.001) and cataract surgery (aHR: 2.90; P = 0.006). Baseline visual acuity was worse in the iCAU group compared to the JIA-U group (20/25 vs. 20/20, respectively; P < 0.001), but improved in the iCAU group after 5 years (20/20 vs. 20/20, respectively; P = 0.052). At the 5-year follow-up, the younger children with iCAU (≤8 years of age at diagnosis) had a higher prevalence of posterior synechiae (aHR: 2.56; P = 0.007), secondary glaucoma (aHR: 16.0; P = 0.020), and cataract surgery (aHR: 4.79; P = 0.004) compared to older children with iCAU (≥9 years at diagnosis).

CONCLUSIONS

Vision-threatening ocular complications are more common in children with iCAU compared to children with JIA-U, particularly in cases in which the onset of uveitis occurred at ≤8 years of age. However, the long-term vision of these children can be improved with adequate treatment.

Persistence of Juvenile Idiopathic Arthritis-Associated Uveitis in Adulthood: A Retrospective Study

Background: Juvenile idiopathic arthritis (JIA) is a rheumatic condition of childhood that is frequently associated with anterior chronic uveitis. Evidence suggests that uveitis may persist up to adulthood in some cases, possibly causing severe visual impairment. Methods: We conducted a retrospective study on a series of patients aged 16 years or older with JIA-related active uveitis who were referred to the Uveitis Service of Sapienza University of Rome from 1990 to 2019 to evaluate the characteristics of ocular disease in patients with JIA-associated uveitis (JIA-U) who still exhibit uveitis in adulthood. Data on clinical features, treatment, complications and visual outcomes were collected. Results: Twenty adults (85% female; median age 23.4 ± 6.6 years, range 16−38 years) with ongoing uveitis (35 eyes) were identified. The median age at JIA onset was 6.15 ± 2.9 years (range 2−10), and uveitis onset was 8.7 ± 4.7 years (range 3−20). The patients were observed in a median follow-up of 16 ± 7.7 years (range 4−35). Fifty-seven percent of affected eyes (20 eyes) had good visual acuity (>0.4 logMAR), while eleven percent of affected eyes (4 eyes) were blind (≤20/200). Uveitis required topical steroids and mydriatic/cycloplegic in all cases. Orbital steroid injection was performed in 13 eyes. Systemic corticosteroids and biologic drugs were used in 14 patients. Conclusions: Although the visual prognosis of JIA-U has improved in recent years, persistent uveitis up to adulthood is still observed. Therefore, protracted follow-up of JIA-U patients is warranted because of the high burden of delayed visual complications.

Ocular manifestations of systemic diseases in children

Knowledge of ocular diseases and understanding of the complex interplay between eye and systemic health have increased over the years. This knowledge is particularly important when caring for our youngest and most vulnerable paediatric patients when ophthalmic manifestations may provide an insight to underlying systemic diseases and can act as the first indicator of an undiagnosed systemic condition. Further, the visual system can be vulnerable to manifestations of known systemic disease, with vigilant ophthalmic examination generally aiding early identification of ocular complications for collaborative multidisciplinary care to prevent avoidable vision loss. The potential ocular signs and complications of the following developmental, genetic or acquired childhood systemic disorders are presented: premature birth, trisomy 21, albinism, Marfan's syndrome, Stickler's syndrome, septo-optic dysplasia, aniridia, neurofibromatosis 1, Sturge-Weber syndrome, papilloedema, juvenile idiopathic arthritis and vitamin A deficiency. Rather than providing an exhaustive list of diseases, this review offers an overview of the more commonly encountered congenital or acquired childhood systemic conditions that have associated childhood ophthalmic disorders and presents referral and ongoing surveillance recommendations.

Long-Term Control of Macular Edema With Adalimumab After Cataract Surgery in a Japanese Child With Juvenile Idiopathic Arthritis: Case Report and Review of 26 Japanese Patients

Juvenile idiopathic arthritis–associated uveitis is rare in the Japanese population. In this article, we report a child whose macular edema was controlled for years after cataract surgery with adalimumab, and reviewed 26 Japanese patients in the literature. In this case report, a 4-year-old boy developed band keratopathy, posterior iris synechiae, and complicated cataract in both eyes. Oral prednisolone prescribed at another hospital was discontinued due to high intraocular pressure in both eyes as a steroid responder. At the age of 5 years, he started oral methotrexate 8 mg weekly for recurrent bilateral iridocyclitis and then underwent lensectomy with core vitrectomy in both eyes. Planned intraocular lens implantation was cancelled at surgery because the anterior vitreous had severe inflammatory opacity with diffuse retinal edema in both eyes. Due to persistent macular edema in both eyes 5 months postoperatively, at the age of 6 years, he began to use adalimumab injection 20 mg every 2 weeks. The macular structure depicted by optical coherence tomography became normal in 2 months. At final visit at the age of 11 years, he had the best-corrected visual acuity of 0.8 in the right eye and 0.4 in the left eye, with adalimumab 40 mg every 2 weeks and methotrexate 8 mg weekly. In conclusion, macular edema persistent despite oral methotrexate after cataract surgery could be controlled for long term by adalimumab in a child with juvenile idiopathic arthritis. In the Japanese literature, only 26 additional cases with juvenile idiopathic arthritis–associated uveitis have been reported so far.

Classification Criteria for Juvenile Idiopathic Arthritis-Associated Chronic Anterior Uveitis

PURPOSE

To determine classification criteria for juvenile idiopathic arthritis (JIA)-associated chronic anterior uveitis (CAU).

DESIGN

Machine learning of cases with JIA CAU and 8 other anterior uveitides.

METHODS

Cases of anterior uveitides were collected in an informatics-designed preliminary database, and a final database was constructed of cases achieving supermajority agreement on the diagnosis, using formal consensus techniques. Cases were split into a training set and a validation set. Machine learning using multinomial logistic regression was used on the training set to determine a parsimonious set of criteria that minimized the misclassification rate among the anterior uveitides. The resulting criteria were evaluated on the validation set.

RESULTS

One thousand eighty-three cases of anterior uveitides, including 202 cases of JIA CAU, were evaluated by machine learning. The overall accuracy for anterior uveitides was 97.5% in the training set and 96.7% in the validation set (95% confidence interval 92.4, 98.6). Key criteria for JIA CAU included (1) chronic anterior uveitis (or, if newly diagnosed, insidious onset) and (2) JIA, except for the systemic, rheumatoid factor-positive polyarthritis, and enthesitis-related arthritis variants. The misclassification rates for JIA CAU were 2.4% in the training set and 0% in the validation set.

CONCLUSIONS

The criteria for JIA CAU had a low misclassification rate and seemed to perform well enough for use in clinical and translational research.

Pediatric uveitis: A comprehensive review

Pediatric uveitis accounts for 5-10% of all uveitis. Uveitis in children differs from adult uveitis in that it is commonly asymptomatic and can become chronic and cause damage to ocular structures. The diagnosis might be delayed for multiple reasons, including the preverbal age and difficulties in examining young children. Pediatric uveitis may be infectious or noninfectious in etiology. The etiology of noninfectious uveitis is presumed to be autoimmune or autoinflammatory. The most common causes of uveitis in this age group are idiopathic and juvenile idiopathic arthritis-associated uveitis. The stepladder approach for the treatment of pediatric uveitis is based on expert opinion and algorithms proposed by multidisciplinary panels. Uveitis morbidities in pediatric patients include cataract, glaucoma, and amblyopia. Pediatric patients with uveitis should be frequently examined until remission is achieved. Once in remission, the interval between follow-up visits can be extended; however, it is recommended that even after remission the child should be seen every 8-12 weeks depending on the history of uveitis and the medications used. Close follow up is also necessary as uveitis can flare up during immunomodulatory therapy. It is crucial to measure the impact of uveitis, its treatment, and its complications on the child and the child's family. Visual acuity can be considered as an acceptable criterion for assessing visual function. Additionally, the number of cells in the anterior chamber can be a measure of disease activity. We review different aspects of pediatric uveitis. We discuss the mechanisms of noninfectious uveitis, including autoimmune and autoinflammatory etiologies, and the risks of developing uveitis in children with systemic rheumatologic diseases. We address the risk factors for developing morbidities, the Standardization of Uveitis Nomenclature (SUN) criteria for timing and anatomical classifications, and describe a stepladder approach in the treatment of pediatric uveitis based on expert opinion and algorithms proposed by multi-disciplinary panels. In this review article, We describe the most common entities for each type of anatomical classification and complications of uveitis for the pediatric population. Additionally, we address monitoring of children with uveitis and evaluation of Quality of Life.

Cataract Surgery with or without Intraocular Lens Implantation in Pediatric Uveitis: A Systematic Review with Meta-Analyses

PURPOSE

To systematically review the results of comparative studies of modern cataract surgery in pediatric uveitis with or without intraocular lens (IOL) implantation and to perform comparative meta-analyses to compare visual acuity outcomes and complication rates.

METHODS

On 12 November 2020, we systematically searched the Cochrane Central, PubMed/MEDLINE, EMBASE, ClinicalTrials.gov, and all affiliated databases of the Web of Science. Two authors independently reviewed studies and extracted data. Studies were reviewed qualitatively in text and quantitatively with meta-analyses. Outcome measures were preoperative and postoperative best-corrected visual acuity (BCVA), inflammation control, and rates of postoperative complications.

RESULTS

Ten studies of 288 eyes were eligible for review of which the majority were eyes with juvenile idiopathic arthritis-associated uveitis. Summary estimates revealed that the BCVA was better in pseudophakic eyes vs. aphakic eyes (1-year postoperative: -0.23 logMAR, 95% CI: -0.43 to -0.03 logMAR, P=0.027; 5-year postoperative: -0.35 logMAR, 95% CI: -0.51 to -0.18 logMAR, P=0.000036). Pseudophakic eyes had more visual axis opacification (OR 6.76, 95% CI: 2.73 to 16.8, P=0.000036) and less hypotony (OR 0.19, 95% CI: 0.04 to 0.95, P=0.044).

CONCLUSIONS

In modern era cataract surgery on eyes with pediatric uveitis with IOL implantation leads to satisfactory and superior visual outcomes and no differences in complication rates apart from an increased prevalence of visual axis opacification and a decreased prevalence of hypotony when compared to aphakia. However, limitations of the retrospective design and the presence of selection bias necessitate a careful interpretation.

Immunological tests and their interpretation in uveitis

Uveitis is a complex disorder including both infectious and non-infectious etiologies. Clinical diagnosis is a challenge because many diseases share common clinical signs. Laboratory support is crucial for confirming the clinical diagnosis. Laboratory diagnosis includes direct tests and indirect tests. For example smear, culture, and molecular diagnostics demonstrate the pathogens, hence they are direct tests. Immunologic tests employ an antigen to detect presence of antibodies to a pathogen, or an antibody to detect the presence of an antigen, of the pathogen in the specimens. The immunological tests used in laboratories are made by producing artificial antibodies that exactly “match” the pathogen in question. When these antibodies come into contact with a sample they bind to the matching pathogen if found in the sample. Hence they are grouped under indirect evidence. There are several investigations in uveitis to reach the confirmed diagnosis including microbiological, immunological, imaging and molecular diagnostic testing. In this section we will discuss immunological investigations of infectious and non-infectious uveitis.

Recommendations for the management of childhood juvenile idiopathic arthritis-type chronic anterior uveitis

IMPORTANCE

Australian- and New Zealand-based, uveitis-specialized ophthalmologists have produced recommendations for the management of juvenile idiopathic arthritis (JIA)-type chronic anterior uveitis.

BACKGROUND

Historically, the visual prognosis of JIA-type chronic anterior uveitis has been poor. New medical advances are likely to improve outcomes, but recently published guidelines are tailored for ophthalmic care in Europe and the United States.

DESIGN

This work involved a consensus survey and a panel meeting.

PARTICIPANTS

The Australian and New Zealand JIA-Uveitis Working Group (29 ophthalmologists) participated in the work.

METHODS

The Delphi technique was used to achieve consensus.

MAIN OUTCOME MEASURES

This work yielded consensus statements.

RESULTS

The Working Group achieved consensus around 18 statements related to clinical evaluation, use of topical and regional corticosteroids, use of systemic corticosteroid and non-corticosteroid immunomodulatory drugs, and management of secondary cataract and glaucoma in childhood JIA-type uveitis.

CONCLUSIONS AND RELEVANCE

Recommendations of the Australian and New Zealand JIA-Uveitis Working Group provide current and regionally applicable advice for managing chronic anterior uveitis in children with JIA.

Multimodal imaging in pediatric uveitis

Pediatric uveitis accounts for up to 10% of all uveitis cases, so special attention must be paid to ensure early diagnosis as well as treatment and follow-up of these young patients in order to decrease the risk of possible ocular complications and consequently vision loss. Multimodal imaging has been an effective and important adjunct in the diagnoses and management of uveitis, especially in children. Reviewed here are the currently utilized modalities, advances, as well as their applications in juvenile idiopathic arthritis-associated uveitis, pars planitis, retinal vasculitis, tubulointerstitial nephritis and uveitis syndrome, Behçet disease, Blau syndrome, and Vogt-Koyanagi-Harada syndrome.

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.

Adalimumab in combination with methotrexate for refractory uveitis associated with juvenile idiopathic arthritis: a RCT

BACKGROUND

Children with juvenile idiopathic arthritis (JIA) are at risk of uveitis. The role of adalimumab (Humira^®; AbbVie Inc., Ludwigshafen, Germany) in the management of uveitis in children needs to be determined.

OBJECTIVE

To compare the efficacy, safety and cost-effectiveness of adalimumab in combination with methotrexate (MTX) versus placebo with MTX alone, with regard to controlling disease activity in refractory uveitis associated with JIA.

DESIGN

This was a randomised (applying a ratio of 2 : 1 in favour of adalimumab), double-blind, placebo-controlled, multicentre parallel-group trial with an integrated economic evaluation. A central web-based system used computer-generated tables to allocate treatments. A cost-utility analysis based on visual acuity was conducted and a 10-year extrapolation by Markov modelling was also carried out.

SETTING

The setting was tertiary care centres throughout the UK.

PARTICIPANTS

Patients aged 2-18 years inclusive, with persistently active JIA-associated uveitis (despite optimised MTX treatment for at least 12 weeks).

INTERVENTIONS

All participants received a stable dose of MTX and either adalimumab (20 mg/0.8 ml for patients weighing < 30 kg or 40 mg/0.8 ml for patients weighing ≥ 30 kg by subcutaneous injection every 2 weeks based on body weight) or a placebo (0.8 ml as appropriate according to body weight by subcutaneous injection every 2 weeks) for up to 18 months. A follow-up appointment was arranged at 6 months.

MAIN OUTCOME MEASURES

Primary outcome - time to treatment failure [multicomponent score as defined by set criteria based on the Standardisation of Uveitis Nomenclature (SUN) criteria]. Economic outcome - incremental cost per quality-adjusted life-year (QALY) gained from the perspective of the NHS in England and Personal Social Services providers. Full details of secondary outcomes are provided in the study protocol.

RESULTS

A total of 90 participants were randomised (adalimumab, n = 60; placebo, n = 30). There were 14 (23%) treatment failures in the adalimumab group and 17 (57%) in the placebo group. The analysis of the data from the double-blind phase of the trial showed that the hazard risk (HR) of treatment failure was significantly reduced, by 75%, for participants in the adalimumab group (HR 0.25, 95% confidence interval 0.12 to 0.51; p < 0.0001 from log-rank test). The cost-effectiveness of adalimumab plus MTX was £129,025 per QALY gained. Adalimumab-treated participants had a much higher incidence of adverse and serious adverse events.

CONCLUSIONS

Adalimumab in combination with MTX is safe and effective in the management of JIA-associated uveitis. However, the likelihood of cost-effectiveness is < 1% at the £30,000-per-QALY threshold.

FUTURE WORK

A clinical trial is required to define the most effective time to stop therapy. Prognostic biomarkers of early and complete response should also be identified.

TRIAL REGISTRATION

Current Controlled Trials ISRCTN10065623 and European Clinical Trials Database number 2010-021141-41.

FUNDING

This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 23, No. 15. See the NIHR Journals Library website for further project information. This trial was also funded by Arthritis Research UK (grant reference number 19612). Two strengths of adalimumab (20 mg/0.8 ml and 40 mg/0.8 ml) and a matching placebo were manufactured by AbbVie Inc. (the Marketing Authorisation holder) and supplied in bulk to the contracted distributor (Sharp Clinical Services, Crickhowell, UK) for distribution to trial centres.

Uveitis in Juvenile Idiopathic Arthritis: 18-Year Outcome in the Population-based Nordic Cohort Study

PURPOSE

To assess the long-term outcome of uveitis in juvenile idiopathic arthritis (JIA).

DESIGN

Population-based, multicenter, prospective JIA cohort, with a cross-sectional assessment of JIA-associated uveitis (JIA-U) 18 years after the onset of JIA.

PARTICIPANTS

A total of 434 patients with JIA, of whom 96 had uveitis, from defined geographic areas of Denmark, Finland, Norway, and Sweden.

METHODS

Patients with onset of JIA between January 1997 and June 2000 were prospectively followed for 18 years. Pediatric rheumatologists and ophthalmologists collected clinical and laboratory data.

MAIN OUTCOME MEASURES

Cumulative incidence of uveitis and clinical characteristics, JIA and uveitis disease activity, ocular complications, visual outcome, and risk factors associated with the development of uveitis-related complications.

RESULTS

Uveitis developed in 96 (22.1%) of 434 patients with JIA. In 12 patients (2.8%), uveitis was diagnosed between 8 and 18 years of follow-up. Systemic immunosuppressive medication was more common among patients with uveitis (47/96 [49.0%]) compared with patients without uveitis (78/338 [23.1%]). Active uveitis was present in 19 of 78 patients (24.4%) at the 18-year visit. Ocular complications occurred in 31 of 80 patients (38.8%). Short duration between the onset of JIA and the diagnosis of uveitis was a risk factor for developing ocular complications (odds ratio [OR], 1.4; 95% confidence interval [CI], 1.1-1.8). Patients with a diagnosis of uveitis before the onset of JIA all developed cataract and had an OR for development of glaucoma of 31.5 (95% CI, 3.6-274). Presence of antinuclear antibodies (ANAs) was also a risk factor for developing 1 or more ocular complications (OR, 3.0; 95% CI, 1.2-7.7). Decreased visual acuity (VA) <6/12 was found in 12 of 135 eyes (8.9%) with uveitis, and 4 of 80 patients (5.0%) with JIA-U had binocular decreased VA <6/12.

CONCLUSIONS

Our results suggest that uveitis screening should start immediately when the diagnosis of JIA is suspected or confirmed and be continued for more than 8 years after the diagnosis of JIA. Timely systemic immunosuppressive treatment in patients with a high risk of developing ocular complications must be considered early in the disease course to gain rapid control of ocular inflammation.

Laser Flare Photometry: A Useful Tool for Monitoring Patients with Juvenile Idiopathic Arthritis-associated Uveitis

PURPOSE

We evaluated laser flare photometry (LFP) values in patients with juvenile idiopathic arthritis (JIA)-associated uveitis.

METHODS

Retrospective study. A decrease of the LFP value between baseline visit and 1 month after anti-inflammatory treatment intensification allowed us to define two groups of patients: group 1 (decreased LFP value ≥50%) and group 2 (<50%). We evaluated the prevalence of vision-threatening complications in both groups.

RESULTS

Fifty-four patients (87 eyes) were followed for 9.9 ± 5 years. Group 1 eyes (n = 54) had significantly fewer ocular complications than group 2 eyes (n = 33) at both 5 years visit (p = .03) and final visit (p = .047). At the final visit, group 2 eyes had significantly more band keratopathy, trabeculectomy, cataract surgery, glaucoma and papille edema. Group 1 eyes kept a better visual acuity (p < .0001).

CONCLUSION

The decrease of LFP values ≥50% of the initial value 1 month after treatment intensification is a good early prognostic factor.

Prospective Determination of the Incidence and Risk Factors of New-Onset Uveitis in Juvenile Idiopathic Arthritis: The Research in Arthritis in Canadian Children Emphasizing Outcomes Cohort

OBJECTIVE

Identification of the incidence of juvenile idiopathic arthritis (JIA)-associated uveitis and its risk factors is essential to optimize early detection. Data from the Research in Arthritis in Canadian Children Emphasizing Outcomes inception cohort were used to estimate the annual incidence of new-onset uveitis following JIA diagnosis and to identify associated risk factors.

METHODS

Data were reported every 6 months for 2 years, then yearly to 5 years. Incidence was determined by Kaplan-Meier estimators with time of JIA diagnosis as the reference point. Univariate log-rank analysis identified risk factors and Cox regression determined independent predictors.

RESULTS

In total, 1,183 patients who enrolled within 6 months of JIA diagnosis met inclusion criteria, median age at diagnosis of 9.0 years (interquartile range [IQR] 3.8-12.9), median follow-up of 35.2 months (IQR 22.7-48.3). Of these patients, 87 developed uveitis after enrollment. The incidence of new-onset uveitis was 2.8% per year (95% confidence interval [95% CI] 2.0-3.5) in the first 5 years. The annual incidence decreased during follow-up but remained at 2.1% (95% CI 0-4.5) in the fifth year, although confidence intervals overlapped. Uveitis was associated with young age (<7 years) at JIA diagnosis (hazard ratio [HR] 8.29, P < 0.001), positive antinuclear antibody (ANA) test (HR 3.20, P < 0.001), oligoarthritis (HR 2.45, P = 0.002), polyarthritis rheumatoid factor negative (HR 1.65, P = 0.002), and female sex (HR 1.80, P = 0.02). In multivariable analysis, only young age at JIA diagnosis and ANA positivity were independent predictors of uveitis.

CONCLUSION

Vigilant uveitis screening should continue for at least 5 years after JIA diagnosis, and priority for screening should be placed on young age (<7 years) at JIA diagnosis and a positive ANA test.

Predictive factors and biomarkers for the 2-year outcome of uveitis in juvenile idiopathic arthritis: data from the Inception Cohort of Newly diagnosed patients with Juvenile Idiopathic Arthritis (ICON-JIA) study

Objective

To define predictors for the 2-year outcome in terms of achieving inactivity, subsequent uveitis reactivation and occurrence of uveitis-related complications of JIA-associated uveitis.

Methods

Demographic and clinical parameters and serum samples of JIA-associated uveitis patients enrolled in ICON at ⩽1 year of JIA diagnosis were collected at study enrolment, every 3 months during the first year and subsequently every 6 months. Predictors for the 2-year outcome were evaluated by linear mixed models.

Results

Of 954 JIA patients included, uveitis occurred in 106 up to the first 2-year follow-up, with 98 of them having complete ophthalmological documentation. In 81.8% and 80.0% of patients, uveitis inactivity was achieved at the 1- and 2-year follow-up after uveitis onset, respectively. JIA onset after the age of 5 years, no use of topical corticosteroids, and adalimumab treatment were significantly associated with an inactive uveitis for at least 6 months (n = 57). Correlates for subsequent uveitis reactivation (n = 16, 30.2%) were age at uveitis onset ⩽5 years and active disease (clinical Juvenile Arthritis Disease Activity Score >4.5). Uveitis-related complications were present in 29.8% of patients at first uveitis documentation and in 30.7% and 32.8% at 1- and 2-year follow-up, respectively. Older age at JIA onset, short duration between JIA and uveitis onset, high anterior chamber (AC) cell grades, poor visual acuity, and topical steroid use at first uveitis documentation correlated with uveitis-related complications.

Conclusion

In addition to demographic risk factors, JIA disease and uveitis activity scores and adalimumab are significant predictors for the 2-year outcome of JIA-associated uveitis patients.

An Unusual Retinal Vessel Modification in Patients Affected by JIA-Uveitis with a Follow-Up Longer Than 16 Years

Purpose

To report unusual and rare clinical changes of retinal vessel pattern in a series of patients affected by Juvenile Idiopathic Arthritis (JIA) uveitis with a follow-up longer than 16 years.

Methods

A series of three patients with JIA-uveitis followed at the University of Rome “Sapienza” from 1998 to 2014 were reported. The retinal vessels were analyzed with fluorescein angiography using Heidelberg Retinal Angiogram-2 (HRA-2; Heidelberg Engineering GmBH, Dossenheim, Germany) and the Topcon TRC-50LX retinal camera (Topcon Europe, The Netherlands). A Spectralis Domain OCT (SD-OCT) (Spectralis Family Heidelberg, Germany) was performed to evaluate vessel anatomy.

Results

Fundus photography showed sheathed vessels localized around the optic disc in every case. Angiography revealed a normal physiology of vessel walls and flow; no sheathing or leakage of dye was observed. SD-OCT demonstrated reflective vessel walls. Vessel lumen appeared patent, and the normal “hourglass configuration” was blurred, but identifiable.

Conclusions

Vessel modifications observed in long-standing JIA-uveitis are not signs of vascular inflammation and are not associated to hypoperfusion. In these cases, ophthalmologists should avoid further invasive investigation and should consider introducing SD-OCT as a routine method to evaluate the vessel changes during the follow-up.

Factors Predictive of Remission of Chronic Anterior Uveitis

PURPOSE

To estimate the incidence of medication-free remission of chronic anterior uveitis and identify predictors thereof.

DESIGN

Retrospective cohort study.

PARTICIPANTS

Patients diagnosed with anterior uveitis of longer than 3 months' duration followed up at United States tertiary uveitis care facilities.

METHODS

Estimation of remission incidence and identification of associated predictors used survival analysis.

MAIN OUTCOME MEASURES

Incidence of medication-free remission. For the primary analysis, remission was defined as inactive uveitis while off treatment at all visits spanning an interval of at least 90 days or-for patients who did not return for follow-up after 90 days-remaining inactive without receiving suppressive medications at all of the last visits. Association of factors potentially predictive of medication-free remission was also studied.

RESULTS

Two thousand seven hundred ninety-five eyes of 1634 patients with chronic anterior uveitis were followed up over 7936 eye-years (4676 person-years). The cumulative medication-free, person-year remission incidence within 5 years was 32.7% (95% confidence interval [CI], 30.4%-35.2%). Baseline clinical factors predictive of reduced remission incidence included longer duration of uveitis at presentation (for 2 to 5 years vs. less than 6 months: adjusted hazard ratio [aHR], 0.61; 95% CI, 0.44-0.83), bilateral uveitis (aHR, 0.75; 95% CI, 0.59-0.96), prior cataract surgery (aHR, 0.70; 95% CI 0.56-0.88), and glaucoma surgery (aHR, 0.63; 95% CI, 0.45-0.90). Two time-updated characteristics were also predictive of reduced remission incidence: keratic precipitates (aHR, 0.36; 95% CI, 0.21-0.60) and synechiae (aHR, 0.62; 95% CI, 0.41-0.93). Systemic diagnosis with juvenile idiopathic arthritis and spondyloarthropathy were also associated with reduced remission incidence. Older age at presentation was associated with higher incidence of remission (for age ≥40 years vs. <40 years: aHR, 1.29; 95% CI, 1.02-1.63).

CONCLUSIONS

Approximately one third of patients with chronic anterior uveitis remit within 5 years. Longer duration of uveitis, younger age, bilateral uveitis, prior cataract surgery, glaucoma surgery, presence of keratic precipitates and synechiae, and systemic diagnoses of juvenile idiopathic arthritis and spondyloarthropathy predict reduced remission incidence; patients with these factors should be managed taking into account the higher probability of a longer disease course.

Risk factors for ocular complications in adult patients with uveitis

PURPOSE

To report risk factors for ocular complications in adults with uveitis.

METHODS

Retrospective cohort study of 653 patients with uveitis (869 eyes) followed up for at least 1 month attended between May 1989 and December 2012.

RESULTS

After a median follow-up of 16 months (interquartile range = 3-59), 43.5% of patients developed one or more complications, including cataract formation (25%), iris alterations (20%), and macular edema (16%) as the most frequent. Older age, intermediate uveitis, chronic course, and uveitis activity >3 months were significantly more frequent among patients with complications. In the multivariate analysis, age ⩾65 years (hazard ratio = 2.76, 95% confidence interval = 1.72-4.4), chronic course (hazard ratio = 1.78, 95% confidence interval = 1.23-259), and uveitis activity >3 months (hazard ratio = 1.94, 95% confidence interval = 1.33-2.84) were predictors of complications.

CONCLUSION

In the present series of patients with uveitis, advanced age, chronic uveitis, and inflammatory activity >12 weeks were risk factors for complications.

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.

High-dose intravenous methylprednisolone in juvenile non-infectious uveitis: A retrospective analysis

Non-infectious uveitis is associated with visual impairment and blindness. Non-biologic treatment for non-infectious uveitis is not based on strong evidence. A retrospective chart review was conducted to investigate treatment response to high-dose intravenous methylprednisolone (IVMP) in children with non-infectious uveitis. Fifty-six patients (93 eyes affected) were included. In 29% uveitis was associated with juvenile idiopathic arthritis. Uveitis predominately affected the anterior segment, was bilateral and recurrent. Complications were common and included visual loss, synechiae, cataract and/or retinal lesions. Patients received up to 5 IVMP at monthly intervals. Visual acuity improved at 3 and 6 months. Anterior chamber cells, synechiae, keratic precipitates, papillary and/or macular edema improved at 3 months. Children treated with ≥3 IVMP (vs 1 IVMP) experienced trends towards fewer relapses, fewer cataracts and less frequently required treatment with biologic agents. High-dose IVMP induce rapid improvement in children with non-infectious uveitis. Prospective randomized trials are required to confirm results.

Effectiveness of long-term infliximab use and impact of treatment adherence on disease control in refractory, non-infectious pediatric uveitis

BACKGROUND

Refractory non-infectious uveitis is a serious condition that leads to ocular complications and vision loss and requires effective systemic treatment to control disease. The effectiveness of long-term infliximab [IFX] in refractory non-infectious childhood uveitis and the impact of treatment adherence on disease control were evaluated.

METHODS

Retrospective, single-center study between December 2002 and April 2016 of 27 children with refractory non-infectious uveitis [17 with juvenile idiopathic arthritis, JIA] treated with long-term IFX [9+ months]. Disease activity was assessed prior to and while on IFX using the Standardization of Uveitis Nomenclature [SUN]. Number of visits per year with active uveitis was analyzed by repeated measures logistic regression analysis from 2 years prior to IFX initiation or from onset of uveitis until most recent visit on IFX. Incomplete treatment adherence was assessed for each visit and defined as any deviance in corticosteroid use, prescribed infusion frequency, and/or follow-up examination frequency.

RESULTS

Primary outcomes were sustained uveitic and systemic disease control prior to and during IFX treatment and the impact of incomplete adherence on uveitic disease control while on IFX. Secondary outcomes included corticosteroid and glaucoma medication requirement, ocular complications and need for surgical intervention. Mean age at IFX initiation was 10.4 ± 4.5 years; initial mean dose was 6.6 ± 2.2 mg/kg [and given at weeks 0, 2, 4 and q4 weeks thereafter for 93%]. Median duration on IFX was 35 [range 9-128] months. Prior to IFX, 14/27 patients had failed adalimumab ± methotrexate [MTX]; 21/27 failed MTX. IFX led to uveitis control in 89% and arthritis control in 76% (13/17). The odds ratio of having controlled disease after IFX was 4.1 (2.6, 6.4) compared to pre-treatment visits. Topical corticosteroids and glaucoma medications were statistically decreased (p = 0.007 right eye [OD], 0.003 left eye [OS] and p = 0.001 OD, p = 0.028 OS respectively). Incomplete adherence to treatment showed 10.3 times greater odds (7.1, 15.0) of having disease activity than full adherence.

CONCLUSIONS

This study adds significantly to the IFX literature by documenting outstanding uveitis control with long-term IFX treatment in non-infectious pediatric uveitis patients. Higher dosage and shorter interval were utilized without adverse effects. Importantly, this is the first study, to our knowledge, to document the significant impact of treatment adherence on uveitis control.

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.

Defining outcome measures in juvenile idiopathic arthritis associated uveitis by a systematic review analysis: do we need a consensus?

BACKGROUND

Juvenile Idiopathic Arthritis associated Uveitis (JIA-U) represents its most frequent extra-articular manifestation and the main cause of childhood uveitis in in developed countries. The broad variety of outcome measures utilized makes the comparison of the disease course, risk for complications, impairment in visual function, and responses to treatment quite difficult. Our aim was to summarize evidence regarding the current availability of outcome measures in JIA-U.

METHODS

A systematic review between January 2000 and December 2018 was performed to identify studies investigating outcome measures used in JIA-U.

RESULTS

The initial search identified 8254 articles of which 89 were potentially eligible. After the full text revision, a total of 27 studies, including 2 RCTs, were included. Among these studies 12 outcome measures for JIA-U use have been identified (grade of cells in the AC, grade of flare in the AC, VA, amblyopia, structural complications, use and sparing of oral corticosteroids and immunosuppressive drugs, surgery requirement, biomarkers, bilateral disease, JIA persistence, quality of life assessments, uveitis subtype). As regards primary outcome measures, 44% among studies included one or more variables related to disease activity (i.e. grade of flare, grade of cells); 56% included visual function performance (i.e. visual acuity); 68% (17/25) included one or more variables of disease-associated tissue damage or complications (i.e. cataract, amblyopia); 24% included disease features (i.e. bilateral disease; uveitis subtype); 44% included laboratory features (i.e. biomarkers); 8% included JIA features (i.e. persistence of disease); 12% included quality of life (i.e. EYE-Q); 44% included management (i.e. use and sparing of oral corticosteroids and other immunosuppressive drugs; surgery requirement).

CONCLUSIONS

Our systematic review surveys the heterogeneity around outcome measures related to JIA-U in children, even in RCTs. It does not provide the solution to overcome the heterogeneity in uveitis studies, but it does provide an estimate of the scale of the problems and provides data to inform this important debate; highlighting the requirement to obtain a new consensus regarding a common approach to identify suitable and efficient outcome measures in JIA-U.

Clinical features and characteristics of uveitis associated with juvenile idiopathic arthritis in Japan: first report of the pediatric rheumatology association of Japan (PRAJ)

BACKGROUND

Although there are many reports on Juvenile Idiopathic arthritis-associated uveitis (JIA-U) from various countries, especially from Europe and North America, there are few reports from Asia. Our aim was to investigate the epidemiology, characteristics and predictors of JIA-U in Japan.

METHODS

Data were retrospectively collected on 726 patients with JIA from medical records as of April 2016 at 15 medical centers specialized in pediatric rheumatic diseases. Of these, patients with uveitis were further investigated for the specific characteristics of this manifestation.

RESULTS

The prevalence of uveitis was 6.1% in the 726 JIA patients examined. Incidence of uveitis was significantly higher in patients with an earlier arthritis onset (2.6-vs.-5.8 years, P < 0.0001), oligoarthritis (16.1%-vs.-1.6%, P < 0.001), or anti-nuclear antibodies. On the contrary, it was significantly less common in patients with rheumatoid factor or anti-cyclic citrullinated peptide antibodies. A history of using methotrexate (MTX), infliximab or adalimumab was also associated with uveitis occurrence. The median age at uveitis diagnosis was 5 years, and the median time from arthritis onset to uveitis diagnosis was 2 years. The occurrence of anterior and bilateral uveitis was 79.3 and 53.7%, respectively. There were no symptoms at uveitis diagnosis in 58.5% of cases. Complications arising between the time of uveitis diagnosis and the last observation increased from 31.7 to 56.1%; in particular, cataract was increased 3-fold. While no patients lost their vision, 61.9% did not recover normal vision (≥ 1.0), and in many cases active uveitis persisted, especially in males. In addition to steroid eye drops (97.6%) and MTX (15.4%), biological agents were used for treating the uveitis in 41.5% of patients.

CONCLUSIONS

The epidemiology, characteristics and predictors of JIA-U in Japan are described here for the first time. Although the prevalence of JIA-U in Japan is lower than in predominantly Caucasian cohorts, as reported from North America and Europe, the epidemiology, characteristics and predictors were found to be similar.

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.

Clinical practice guidance for juvenile idiopathic arthritis (JIA) 2018

Juvenile idiopathic arthritis (JIA) is the most common disease in pediatric rheumatism. There is no specific symptom or examination finding for JIA, and the diagnosis is made by exclusion and differentiation. Because non-pediatric rheumatologists are sometimes involved in medical care, 'proposal for JIA guidance on diagnosis and treatment for primary care pediatricians and non-pediatric rheumatologists' was first published in 2007. In these 10 years, a number of new findings on pathophysiology and treatment of JIA have been published; therefore, we propose this guidance of 2018th edition aiming at updating and standardization of JIA medical care in Japan. This edition included the management of uveitis, macrophage activation syndrome, infectious diseases before and during treatment. Moreover, details of biologics are also described. Although this guidance is tailored to adaptation of examinations and drugs, we do not purpose to limit the physicians' discretion in clinical practice. This guidance should be viewed as recommendations and be individualized according to the condition of the patient. We hope that medical care for JIA will advance and more patients will get benefit based on this guidance. Then, further revisions are needed due to changes in future conditions.

Risk Factors and Biomarkers for the Occurrence of Uveitis in Juvenile Idiopathic Arthritis: Data From the Inception Cohort of Newly Diagnosed Patients With Juvenile Idiopathic Arthritis Study

OBJECTIVE

To analyze the prognostic value of demographic, clinical, and therapeutic factors and laboratory biomarkers and to assess their role in predicting uveitis occurrence in patients with juvenile idiopathic arthritis (JIA).

METHODS

Patients with JIA were enrolled within the first year after JIA diagnosis. Demographic and clinical parameters were documented. Serum samples were collected at study enrollment, at 3-month follow-up visits within the first year, and then every 6 months. A multivariable Cox regression analysis was performed to evaluate the impact of demographic, clinical, laboratory, and therapeutic parameters on uveitis onset.

RESULTS

We included 954 JIA patients (67.2% female, 54.2% antinuclear antibody [ANA] positive, mean ± SD age at onset 7.1 ± 4.6 years). Uveitis occurred in 133 patients (observation period 44.5 months). Young age at JIA onset and ANA positivity were significantly associated with the onset of uveitis (both P < 0.001). Treatment of arthritis with methotrexate alone (hazard ratio [HR] 0.18 [95% confidence interval (95% CI) 0.12-0.29], P < 0.001) or combined with etanercept (HR 0.10 [95% CI 0.04-0.23], P < 0.001) or adalimumab (HR 0.09 [95% CI 0.01-0.61], P = 0.014) reduced the risk of uveitis onset and the occurrence of uveitis-related complications. Predictors of uveitis onset included elevated erythrocyte sedimentation rate at baseline (HR 2.36 [95% CI 1.38-4.02], P = 0.002) and continuing moderate or high disease activity during follow-up as measured by the 10-joint clinical Juvenile Arthritis Disease Activity Score (HR 4.30 [95% CI 2.51-7.37], P < 0.001). Additionally, S100A12 levels ≥250 ng/ml at baseline were significantly associated with the risk of uveitis (HR 2.10 [95% CI 1.15-3.85], P = 0.016).

CONCLUSION

Apart from demographic risk factors and treatment modalities, JIA disease activity scores and laboratory biomarkers could be used to better define the group of JIA patients at high risk of uveitis onset.

Consensus-based recommendations for the management of uveitis associated with juvenile idiopathic arthritis: the SHARE initiative

BACKGROUND

In 2012, a European initiative called Single Hub and Access point for pediatric Rheumatology in Europe (SHARE) was launched to optimise and disseminate diagnostic and management regimens in Europe for children and young adults with rheumatic diseases. Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children and uveitis is possibly its most devastating extra-articular manifestation. Evidence-based guidelines are sparse and management is mostly based on physicians' experience. Consequently, treatment practices differ widely, within and between nations.

OBJECTIVES

To provide recommendations for the diagnosis and treatment of JIA-associated uveitis.

METHODS

Recommendations were developed by an evidence-informed consensus process using the European League Against Rheumatism standard operating procedures. A committee was constituted, consisting of nine experienced paediatric rheumatologists and three experts in ophthalmology from Europe. Recommendations derived from a validated systematic literature review were evaluated by an Expert Committee and subsequently discussed at two consensus meetings using nominal group techniques. Recommendations were accepted if >80% agreement was reached (including all three ophthalmologists).

RESULTS

In total, 22 recommendations were accepted (with >80% agreement among experts): 3 on diagnosis, 5 on disease activity measurements, 12 on treatment and 2 on future recommendations.

CONCLUSIONS

The SHARE initiative aims to identify best practices for treatment of patients suffering from JIA-associated uveitis. Within this remit, recommendations for the diagnosis and treatment of JIA-associated uveitis have been formulated by an evidence-informed consensus process to suggest a standard of care for JIA-associated uveitis patients throughout Europe.

Comparison of uveitis in the course of juvenile idiopathic arthritis with isolated uveitis in children - own experiences

Objectives

Uveitis and juvenile idiopathic arthritis (JIA) relatively often coexist. Inflammatory changes in the anterior segment of the eye are the most common extra-articular symptom in children with JIA, and JIA is, in turn, the main systemic cause of anterior uveitis in children. The aim of our study was to compare the course of anterior uveitis accompanying JIA and isolated uveitis.

Material and methods

We analyzed 25 children with JIA and uveitis (group I) and 28 children with isolated uveitis (group II). The study population was retrospectively selected from the patients treated in our center in the years 1998–2016 through a search of the hospital database. All data were presented as descriptive statistics.

Results

In group I there was a higher percentage of girls than in group II (64% vs. 50%) and uveitis occurred at a significantly younger age (8.7 years vs. 11.6). Patients from group I more often presented with immunological abnormalities (positive antinuclear antibodies or HLA-B27 antigen). The majority of children from group I developed uveitis prior to (44%) or simultaneously with (20%) arthritis. In patients who first presented with uveitis, arthritis appeared on average after 28 months (median 12 months). In children in whom arthritis developed first, uveitis appeared on average after 51 months (median 36 months). In some patients the time interval between the involvement of these two organs was as long as 9–10 years. Four children from group I and three from group II were qualified for biological treatment.

Conclusions

The results of our analysis indicate the need for constant cooperation between the pediatric rheumatologist and the ophthalmologist. Although the risk of uveitis in JIA decreases with the disease duration, in some cases this complication can develop after many years. Children with present antinuclear antibodies, at younger age and of female gender should be subject to particularly close observation.

Assessment of the outcome of ophthalmological screening for uveitis in a cohort of Swedish children with juvenile idiopathic arthritis

PURPOSE

To describe clinical features, risk factors and complications in a cohort of Swedish children with juvenile idiopathic arthritis (JIA) screened for uveitis between 2002 and 2011.

METHODS

Medical records of 299 children with JIA (93 male, 206 female; median age 5.0 years at diagnosis) were retrospectively scrutinized focusing on subtype of JIA, onset of arthritis/uveitis, presence of antinuclear antibodies (ANA) and ophthalmological status.

RESULTS

Uveitis was found in 32 (11%) children, 78% bilaterally affected. The median age of arthritis onset in children who developed uveitis was 2.5 years (range 1-10) versus 5.0 years (range 1-15) in those who did not. Sex ratio was 3.5:1 (girl:boy). The most prevalent JIA subtype was oligoarthritis (75%). All but one child with uveitis was found to be ANA (+). The median interval between diagnosis of arthritis and uveitis was 12 months. Only one child developed uveitis between the fourth and fifth years after arthritis onset. Ocular complications were recorded in 45.6% (26/57 affected eyes) at last follow-up. On univariate analysis, both young age at arthritis onset and ANA positivity were possible predictors for developing uveitis, but on multivariate analysis, the latter was the most important predictor (HR 16.25, 95%; CI 2.19-120.44; p = 0.006, Cox regression analysis).

CONCLUSION

Almost all of the children developing JIA-associated uveitis did so within 4 years after arthritis onset, a fact that accentuates the importance of early initiation of ophthalmological screening and more frequent regular follow-ups during the first 4 years. The most important predictor for developing uveitis was ANA positivity.
