Recent advances in uveitis of juvenile idiopathic arthritis

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.

Bilateral Granulomatous Iridocyclitis Associated with Early-Onset Juvenile Psoriatic Arthritis

PURPOSE

The purpose of this study is to report on a case of bilateral granulomatous iridocyclitis in a patient with early-onset juvenile psoriatic arthritis (JPsA).

METHODS

The method used is an observational case report. Observations. A 3-year-old Hispanic girl was sent to our uveitis service for further evaluation of her granulomatous uveitis. The initial ophthalmologic examination revealed bilateral band keratopathy, large mutton-fat keratic precipitates, multiple posterior synechiae, and 4+ anterior chamber cells. The physical exam was notable for left knee edema and right axillary rash. Laboratory testing was remarkable for an erythrocyte sedimentation rate of 80 mm/h, positive antinuclear antibodies (1 : 1, 280), and negative human leukocyte antigen B27. A cutaneous biopsy was obtained, which confirmed the diagnosis of a psoriatic rash. Treatment with oral prednisolone and topical prednisolone acetate with atropine sulfate resulted in the complete resolution of the uveitis. Conclusion and Importance. Bilateral granulomatous iridocyclitis may be a rare presentation of ocular involvement in patients with early-onset JPsA.

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.

Discontinuing adalimumab in patients with controlled juvenile idiopathic arthritis-associated uveitis (ADJUST-Adalimumab in Juvenile Idiopathic Arthritis-associated Uveitis Stopping Trial): study protocol for a randomised controlled trial

Background

Juvenile idiopathic arthritis (JIA)-associated uveitis is a chronic paediatric ocular inflammatory condition that can result in visual impairment. Adalimumab, a tumour necrosis factor (TNF)-alpha inhibitor, effectively controls joint and eye inflammation; however, its long-term use may increase the risk of adverse health outcomes and place an undue financial burden on the patient and healthcare system given its high cost. There is great interest for patients to stop adalimumab following remission due to these reasons but there is a lack of information on the ability to maintain control after discontinuing adalimumab.

Methods

The Adalimumab in Juvenile Idiopathic Arthritis-associated Uveitis Trial (ADJUST) is a multicentred, international trial that will randomise 118 participants aged 2 years and older with controlled JIA-associated uveitis to either continue adalimumab or discontinue adalimumab and receive a placebo. The trial will compare the time to uveitis recurrence between the two groups over 12 months. All participants will receive the standard weight-based dose of adalimumab or placebo: 20 mg biweekly (if < 30 kg) or 40 mg biweekly (if ≥ 30 kg).

Discussion

This is the first randomised controlled trial to assess the efficacy of discontinuing adalimumab after demonstrating control of JIA-associated uveitis for at least 12 months. The results of ADJUST will provide information on clinical outcomes to guide clinicians in their decision-making regarding discontinuation of adalimumab.

Proposal for a definition for response to treatment, inactive disease and damage for JIA associated uveitis based on the validation of a uveitis related JIA outcome measures from the Multinational Interdisciplinary Working Group for Uveitis in Childhood (MIWGUC)

BACKGROUND

JIA-associated uveitis (JIAU) is a serious, sight-threatening disease with significant long-term complications and risk of blindness, even with improved contemporary treatments. The MIWGUC was set up in order to propose specific JIAU activity and response items and to validate their applicability for clinical outcome studies.

METHODS

The group consists of 8 paediatric rheumatologists and 7 ophthalmologists. A consensus meeting took place on November 2015 in Barcelona (Spain) with the objective of validating the previously proposed measures. The validation process was based on the results of a prospective open, international, multi-centre, cohort study designed to validate the outcome measures proposed by the initial MIWGUC group meeting in 2012. The meeting used the same Delphi and nominal group technique as previously described in the first paper from the MIWGUC group (Arthritis Care Res 64:1365-72, 2012). Patients were included with a diagnosis of JIA, aged less than 18 years, and with active uveitis or an uveitis flare which required treatment with a disease-modifying anti-rheumatic drug. The proposed outcome measures for uveitis were collected by an ophthalmologist and for arthritis by a paediatric rheumatologist. Patient reported outcome measures were also measured.

RESULTS

A total of 82 patients were enrolled into the validation cohort. Fifty four percent (n = 44) had persistent oligoarthritis followed by rheumatoid factor negative polyarthritis (n = 15, 18%). The mean uveitis disease duration was 3.3 years (SD 3.0). Bilateral eye involvement was reported in 65 (79.3%) patients. The main findings are that the most significant changes, from baseline to 6 months, are found in the AC activity measures of cells and flare. These measures correlate with the presence of pre-existing structural complications and this has implications for the reporting of trials using a single measure as a primary outcome. We also found that visual analogue scales of disease activity showed significant change when reported by the ophthalmologist, rheumatologist and families. The measures formed three relatively distinct groups. The first group of measures comprised uveitis activity, ocular damage and the ophthalmologists' VAS. The second comprised patient reported outcomes including disruption to school attendance. The third group consisted of the rheumatologists' VAS and the joint score.

CONCLUSIONS

We propose distinctive and clinically significant measures of disease activity, severity and damage for JIAU. This effort is the initial step for developing a comprehensive outcome measures for JIAU, which incorporates the perspectives of rheumatologists, ophthalmologists, patients and families.

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.

Update on the Treatment of Uveitis in Patients with Juvenile Idiopathic Arthritis: A Review

Chronic uveitis is a common extra-articular manifestation of juvenile idiopathic arthritis. The classic clinical picture is one of chronic anterior uveitis, which usually remains asymptomatic until ocular complications arise. The risk of uveitis is increased in girls with an early onset of oligoarthritis and positive antinuclear antibodies. Even though the inflammation in patients with juvenile idiopathic arthritis is initially limited in the anterior part of the eye, chronic active inflammation may eventually cause significant damage to the posterior pole. Complications may include band keratopathy, cataract, secondary glaucoma, posterior synechiae, cystoid macular edema, and hypotony. The cooperation of ophthalmologists with rheumatologists may help define the best treatment plan. The ophthalmic therapeutic regimen includes topical corticosteroids and mydriatics, while in severe cases immunosuppressive and biological agents are introduced. Surgical management of complications might be needed.

Uveitis Associated with Juvenile Idiopathic Arthritis, our Observations

Introduction:

Uveitis as extra-articular manifestation of juvenile idiopathic arthritis (JIA) is present in 20% of children with the persistent form, in 30% with the extended oligoarticular form, while it is present in psoriatic and polyarticular rheumatoid factor (RF) negative arthritis in 10% and 14%, respectively.

Aim:

The aim of the study was to evaluate the frequency of uveitis and its complications in children with JIA.

Material and Methods:

A retrospective study was conducted with an analysis of the medical records of children with JIA who were treated for the last 5 years. The analysis included the following: the child’s age and sex, age at onset of arthritis, of uveitis, complications, RF values and antinuclear antibodies (ANA).

Results:

The study included 97 children with JIA: in 14 (14.4%) uveitis was observed; the most common form of JIA was the oligoarticular extended form (6/14), oligoarticular persistent form was observed in 5 children, while 3 children with uveitis had polyarticular RF negative JIA. The age of arthritis onset was lower in children with uveitis (4.7 vs 8.2 years); ANA positivity was more common in children with JIA and uveitis (64% vs 41%). Uveitis was the first manifestation of the disease for 2 children; 28.6% of children had clinically asymptomatic uveitis, while 42.4% of children developed uveitis within 4 years from the JIA onset. 8/14 children developed uveitis complications: 3 cases of synechia, 2 band keratopathy, 2 cataracta, 1 glaucoma.

Conclusion:

Uveitis as significantly present manifestation of JIA requires to timely recognize, treat, monitor children in order to prevent complications.

Nuclear cataract as an early predictive factor for recalcitrant juvenile idiopathic arthritis-associated uveitis

PURPOSE

To analyze factors predictive of having treatment-resistant uveitis in patients with juvenile idiopathic arthritis (JIA)-associated uveitis.

METHODS

The medical records of patients diagnosed with JIA-associated uveitis treated at a single tertiary referral center from October 2005 to March 2013 were reviewed retrospectively. The main outcome measures were demographic characteristics, ocular comorbidity, clinical course, treatments, and baseline risk factors associated with poor response to first-line therapies.

RESULTS

A total of 96 patients (175 eyes) were included. Of these, 58 patients (108 eyes) required biologic disease-modifying antirheumatic drugs or alkylating agents for their uveitis during follow-up (recalcitrant group), and 38 patients (67 eyes) did not (nonrecalcitrant group). Eyes of the recalcitrant group tended to have a higher incidence of cataract at baseline (49%; P < 0.0001). In the nonrecalcitrant group, the most frequent complications were cataract (20.9%) and secondary glaucoma (20.9%). The mean number of flares in the recalcitrant group was significantly reduced from 3.7/eye/year prior to cataract surgery to 1.6/eye/year after (P < 0.0001). Nuclear cataract was found to be an independent predictor for a severe course of JIA-associated uveitis. Any other type of cataract, posterior synechiae, male sex, or active uveitis at baseline were not found to be independently associated with recalcitrant uveitis.

CONCLUSIONS

Nuclear cataract at baseline evaluation is a risk factor for poor response to first-line therapies in JIA-associated uveitis patients.

Treatment of Juvenile Idiopathic Arthritis-Associated Uveitis

Pediatric uveitis may be a serious health problem because of the lifetime burden of vision loss due to severe complications if the problem is not adequately treated. Juvenile idiopathic arthritis (JIA)-associated uveitis is characterized by insidious onset and potentially blinding chronic anterior uveitis. Periodic ophthalmologic screening is of utmost importance for early diagnosis of uveitis. Early diagnosis and proper immunomodulatory treatment are essential for good visual prognosis. The goal of treatment is to achieve enduring drug-free remission. The choice of therapeutic regimen needs to be tailored to each individual case. One must keep in mind that patients under immunomodulatory treatment should be monitored closely due to possible side effects. Local and systemic corticosteroids have long been the mainstay of therapy; however, long-term corticosteroid therapy should be avoided due to serious side effects. Steroid-sparing agents in the treatment of JIA-associated uveitis include antimetabolites and biologic agents in refractory cases. Among the various immunomodulatory agents, methotrexate is generally the first choice, as it has a well-established safety and efficacy profile in pediatric cases and does not appear to increase the risk of cancer. Other classic immunomodulators that may also be used in combination with methotrexate include azathioprine, mycophenolate mofetil, and cyclosporin A. Biologic agents, primarily tumor necrosis factor alpha inhibitors including infliximab or adalimumab, should be considered in cases of treatment failure with classic immunomodulatory agents.

Controversies in intraocular lens implantation in pediatric uveitis

Cataract is one of the most common and visually debilitating complications of pediatric uveitis. It develops as a consequence of chronic inflammation and steroid use and is seen most often in juvenile idiopathic arthritis (JIA)-associated uveitis. Cataract extraction with intraocular lens (IOL) insertion has been carried out with a measure of success in non-uveitic pediatric eyes, but in cases of uveitis, multiple factors affect the final outcome. Chronic inflammation and its sequelae such as band keratopathy, posterior synechiae, and cyclitic membranes make surgical intervention more challenging and outcome less certain. Postoperative complications like increased inflammation, glaucoma, posterior capsular opacification, retrolental membranes, and hypotony may compromise the visual outcome. Early refractive correction is imperative in pediatric eyes to prevent amblyopia. The use of contact lenses and intraocular lenses in pediatric uveitic eyes were fraught with complications in the past. Surgical interventions such as vitreo-lensectomy followed by contact lens fitting and small incision cataract surgery followed by different types of intraocular lenses have been utilized, and many reports have been published, albeit in small patient groups. This review analyzes and discusses the existing literature on intraocular lens implantation in cases of pediatric uveitic cataract surgery.

The importance of an ophthalmologic examination in patients with juvenile idiopathic arthritis

Uveitis occurs within the first year of arthritis onset in 73% of patients with juvenile idiopathic arthritis (JIA) considered at risk. The intraocular inflammation is characterized by an insidious onset and a silent and chronic clinical course capable of producing significant visual loss due to complications such as: cataract formation, secondary glaucoma, maculopathy and optic neuropathy. The absence of initial signs and symptoms, along with a deficient ophthalmic monitoring produce a delay in diagnosis with serious consequences. It has been estimated that 47% of JIA patients at risk for developing uveitis are legally blind (20/200 or worse) at least in one eye at the time of their first visit to the ophthalmologist. To reduce ocular complications and improve their visual outcome, it is necessary that rheumatologists refer all patients recently diagnosed (within the first month) with JIA for an ophthalmic evaluation, and maintain periodical follow-up visits based on classification and risk category of the disease.

Partial and Total Descemet's Detachments in a Patient with Severe Terrien's Marginal Degeneration and Juvenile Idiopathic Arthritis

A 16-year-old female with juvenile idiopathic arthritis presented with a one-month history of decreasing vision and increasing corneal edema in her left eye. Slit-lamp examination, keratometric measurements, and OCT evaluation led to a diagnosis of Terrien's marginal degeneration in both eyes along with a complete detachment of Descemet's membrane in the left eye and partial detachment in the right eye. She was treated with an intracameral injection of air and then topical betamethasone and chloramphenicol which lead to the resolution of symptoms. We further examine the pathophysiology of this disease based on current literature.

Noninfectious immune-mediated uveitis and ocular inflammation

Noninfectious uveitis encompasses a diverse group of ocular inflammatory disorders that share an underlying immune etiology and may be associated with systemic disease or confined primarily to the eye. Uveitis is commonly classified by anatomical location of inflammation into anterior, intermediate, posterior, and panuveitis. The treatment of noninfectious uveitis consists of corticosteroids, immunosuppressive agents, and surgically placed steroid implants. We review the epidemiology, immunopathology, and clinical features of several noninfectious immune-mediated uveitides, including HLA-B27 acute anterior uveitis, juvenile idiopathic arthritis, intermediate uveitis, sarcoidosis, Behcet's disease, Vogt-Koyanagi-Harada syndrome, sympathetic ophthalmia, and white dot syndromes. We also discuss the stepwise approach to medical treatment of immune-mediated uveitis as well as the characteristics, safety, and efficacy of immunosuppressive agents used to treat ocular inflammatory disease.

Controversies in juvenile idiopathic arthritis-associated uveitis

Abstract Juvenile idiopathic arthritis-associated uveitis (JIAU) accounts for a sizable proportion of uveitis cases in children and is an important cause of ocular morbidity in uveitis patients in this age group. The authors present the results of a survey conducted to obtain a better understanding of the current views and practices of ophthalmologists involved in the care of children with JIAU. A detailed questionnaire consisting of 54 questions addressing epidemiology, diagnosis, and therapy of JIAU was distributed to 67 uveitis specialists. The responses from 37 completed questionnaires were tabulated for this report. While the experts often agreed on aspects of the epidemiologic and clinical features of JIAU and its complications, considerable diversity of responses was noted-particularly with regard to practice patterns. Regarding diagnostics and disease monitoring, all experts favored ANA testing, whereas two-thirds also suggested HLA-B27 typing. Laser flare photometry was available to and routinely used by almost one-third of the experts. Optical coherence tomography (OCT) was used by more than half. The survey revealed an overall consensus on therapeutic strategies, including the use of both conventional immunosuppressive and biologic agents. Methotrexate was the initial choice for immunosuppression by most respondents. Most would add an anti-TNF-alpha agent following failure of traditional immunosuppressive therapy, and adalimumab was favored by almost half of the experts. Questions addressing the management of individual situations, such as the treatment of macular edema and perioperative management, revealed considerable differences in therapeutic approaches. The results of this survey support the development of international guidelines for the management of JIAU.

Usefulness of adalimumab in the treatment of refractory uveitis associated with juvenile idiopathic arthritis

Purpose. To assess the efficacy and safety of adalimumab in patients with juvenile idiopathic arthritis (JIA) and associated refractory uveitis. Design. Multicenter, prospective case series. Methods. Thirty-nine patients (mean [SD] age of 11.5 [7.9] years) with JIA-associated uveitis who were either not responsive to standard immunosuppressive therapy or intolerant to it were enrolled. Patients aged 13–17 years were treated with 40 mg of adalimumab every other week for 6 months and those aged 4–12 years received 24 mg/m² body surface. Results. Inflammation of the anterior chamber (2.02 [1.16] versus 0.42 [0.62]) and of the posterior segment (2.38 [2.97] versus 0.35 [0.71] decreased significantly between baseline and the final visit (P < 0.001). The mean (SD) macular thickness at baseline was 304.54 (125.03) μ and at the end of follow-up was 230.87 (31.12) μ (P < 0.014). Baseline immunosuppression load was 8.10 (3.99) as compared with 5.08 (3.76) at the final visit (P < 0.001). The mean dose of corticosteroids also decreased from 0.25 (0.43) to 0 (0.02) mg (P < 0.001). No significant side effects requiring discontinuation of therapy were observed. Conclusion. Adalimumab seems to be an effective and safe treatment for JIA-associated refractory uveitis and may reduce steroid requirement.

Risk markers of juvenile idiopathic arthritis-associated uveitis in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry

OBJECTIVE

To characterize the epidemiology and clinical course of children with juvenile idiopathic arthritis-associated uveitis (JIA-U) in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry and explore differences between African American (AA) and non-Hispanic white (NHW) children.

METHODS

There were 4983 children with JIA enrolled in the CARRA Registry. Of those, 3967 NHW and AA children were included in this study. Demographic and disease-related data were collected from diagnosis to enrollment. Children with JIA were compared to those with JIA-U. Children with JIA-U were also compared by race.

RESULTS

There were 459/3967 children (11.6%) with JIA-U in our cohort with a mean age (SD) of 11.4 years (± 4.5) at enrollment. Compared to children with JIA, they were younger at arthritis onset, more likely to be female, had < 5 joints involved, had oligoarticular JIA, and were antinuclear antibody (ANA)-positive, rheumatoid factor (RF)-negative, and anticitrullinated protein antibody-negative. Predictors of uveitis development included female sex, early age of arthritis onset, and oligoarticular JIA. Polyarticular RF-positive JIA subtype was protective. Nearly 3% of children with JIA-U were AA. However, of the 220 AA children with JIA, 6% had uveitis; in contrast, 12% of the 3721 NHW children with JIA had uveitis.

CONCLUSION

In the CARRA registry, the prevalence of JIA-U in AA and NHW children is 11.6%. We confirmed known uveitis risk markers (ANA positivity, younger age at arthritis onset, and oligoarticular JIA). We describe a decreased likelihood of uveitis in AA children and recommend further exploration of race as a risk factor in a larger population of AA children.

Risk factors associated with the relapse of uveitis in patients with juvenile idiopathic arthritis: a preliminary report

PURPOSE

To identify risk factors associated with relapse of uveitis in patients with recurrent uveitis associated with juvenile idiopathic arthritis (JIA) after treatment with immunomodulatory therapy (IMT) and durable remission of 1 year.

METHODS

The medical records of 30 patients with JIA-associated uveitis who were successfully treated with IMT to a state of corticosteroid-free remission and subsequently remained in remission after discontinuation of IMT for a period of at least 1 year were retrospectively reviewed. In subsequent follow-up, some patients had relapse of uveitis, whereas others continued to be in remission. Remission was defined as <1 + cells in the anterior chamber and <1 + vitreous haze grading; relapse was defined as ≥ 1 + cell in the anterior chamber or ≥ 1 + vitreous haze grading.

RESULTS

A total of 30 patients were included. Of these, 17 (56.7%) patients remained in uveitic remission, whereas 13 (43.3%) relapsed. The patients in remission received IMT earlier in the course of disease compared with patients who relapsed (median, 12 months vs 72 months; P = 0.002 [Mann-Whitney test]). Patients in remission had received treatment with IMT at a younger age compared with the relapse group (median age, 7 years vs 13 years; P = 0.02 [Mann-Whitney test]). None of the other factors studied revealed a statistically significant association.

CONCLUSIONS

Patients with JIA-associated uveitis who were treated with IMT earlier in the course of disease and at a younger age were associated with a lower rate of relapse of uveitis after durable remission and 1 year of quiescence, compared with similar patients who relapsed.

Cataract management in juvenile idiopathic arthritis: simultaneous versus secondary intraocular lens implantation

PURPOSE

To compare primary versus secondary intraocular lens (IOL) implantation after cataract removal in patients with juvenile idiopathic arthritis (JIA).

METHODS

Retrospective interventional study. Data were obtained for 40 children (40 eyes) with JIA-associated uveitis operated on for cataract before the age of 16 years between January 1998 and January 2005.

RESULTS

Twenty-one patients underwent primary IOL implantation at a mean age of 13.1 ± 2.6 (9-16) years. Mean follow-up was 48.2 ± 5.4 (35-64) months. Nineteen patients underwent cataract removal at a mean age 12.3 ± 2.0 (9-16) years and secondary IOL implantation 13.6 ± 0.3 (11-16) months later. Mean follow-up was 47.2 ± 6.5 (32-64) months. BCVA difference between the two groups was significant at 24-month visit only (p = 0.001). Incidence of secondary glaucoma was significantly lower in the group that underwent secondary IOL implantation (p = 0.01).

CONCLUSION

Secondary IOL implantation after cataract removal in children with JIA-related uveitis provided a significantly lower incidence of secondary glaucoma.

Juvenile idiopathic arthritis-associated uveitis: a nationwide population-based study in Taiwan

OBJECTIVE

The incidence and prevalence of juvenile idiopathic arthritis (JIA) vary widely across the world but data in East Asia is lacking. Uveitis is a serious cause of morbidity in JIA. This study aimed to analyze the incidence and prevalence of JIA, and the characteristics of JIA-associated uveitis in Taiwan.

METHODS

A population-based cohort study was conducted using the Taiwan National Health Insurance Research Database. Each patient was individually tracked from 1999 to 2009 to identify the diagnosis of JIA and uveitis using the International Classification of Diseases diagnostic codes. Multivariate logistic regression was used to determine the risk factors and complications of uveitis in patients with JIA.

RESULTS

The study cohort had 2636 cases of JIA and included juvenile rheumatoid arthritis (57.7%), enthesitis-related arthritis (ERA) (39.2%), and psoriatic arthritis (3.1%). The average annual incidence of JIA and JIA-associated uveitis were 4.93 (range, 3.93-6.23) and 0.25 (range, 0.12-0.37) cases per 100,000 population, respectively. The average period prevalence of JIA was 33.8 cases per 100,000 population. Uveitis occurred in 4.7% of patients with JIA, while JIA-associated uveitis was complicated by cataract (11.2%) and glaucoma (24.8%). Enthesitis-related arthritis was significantly associated with uveitis (OR: 3.47; 95% CI: 2.24-5.37) (p<0.0001). Uveitis diagnosed before JIA was the most significant risk factor for complications of glaucoma or cataract (OR: 3.54; 95% CI: 1.44-8.72) (p = 0.006).

CONCLUSIONS

The incidence of JIA is low but that of JIA-associated uveitis is increasing. Higher percentage of males in patients with ERA and the strong association between ERA and uveitis are unique for children with JIA in Taiwan. Uveitis diagnosed before arthritis is an important risk factor for complications. Continuous ophthalmologic follow-up is needed for children with JIA or uveitis of unknown etiology.

The uveitis and its relationship with disease activity and quality of life in Moroccan children with juvenile idiopathic arthritis

The aim of our study is to investigate ocular involvement in juvenile idiopathic arthritis (JIA) and its relationship with disease activity and quality of life in Moroccan patients who suffer from JIA. This is a cross-sectional study conducted between January and June 2012 which includes patients with juvenile idiopathic arthritis (n = 30). All patients have undergone clinical and paraclinical assessment of JIA and a complete eye examination. Functional impairment is assessed by the Childhood Health Assessment Questionnaire while visual function is studied by the Effect of Youngsters' Eyesight in Quality of Life instrument (EYE-Q). Quality of life is assessed using the Pediatric Quality of Life Inventory Version 4.0 (PedsQL 4.0). Four patients (13.33 %) have uveitis with a confidence interval between 3.4 and 30.7. Involvement is bilateral in three children (75 %). One patient (25 %) has elevated intraocular pressure with loss of the right eye due to glaucoma. There is a strong but not significant relationship between uveitis and the number of awakenings (r = 0.71, p = 0.69) and morning stiffness (r = 3.05, p = 0, 21). This relationship is moderate with erythrocyte sedimentation rate (r = 0.48, p = 0.78) and C-reactive protein (r = 0.25, p = 0.88). A strong but not significant association is found between the overall quality of life assessed by the PedsQL 4.0 and visual function assessed by EYE-Q in the uveitis group (r = -0.64, p = 0.55). This study suggests that uveitis associated with JIA can present serious complications and could have a direct relationship with the activity of the JIA as well as with the quality of life of the patient.

Updates on the risk markers and outcomes of severe juvenile idiopathic arthritis-associated uveitis

Uveitis is the most common extra-articular manifestation of juvenile idiopathic arthritis, which is the most common systemic cause of uveitis in children. Known risk factors for uveitis include antinuclear antibody seropositivity, young age of arthritis onset, specific juvenile idiopathic arthritis subtype and short duration of disease. Risk markers for severe ocular disease include gender, age and complications at initial visit. Due to the risk for vision-compromising sequelae such as cataracts, band keratopathy, glaucoma, vision loss and blindness, an understanding of the risk factors for uveitis development and severe ocular disease is crucial to help prevent serious visual disability and complications. This paper reviews the pathogenesis of uveitis, known risk factors for uveitis development and severe visual outcome, and addresses the need for additional biomarkers of uveitis risk, prognosis and remission.

Prevention and management of cataracts in children with juvenile idiopathic arthritis-associated uveitis

Juvenile idiopathic arthritis (JIA)-associated uveitis can be associated with vision-compromising complications such as cataracts, glaucoma, synechiae, and band keratopathy. Of these, cataracts are one of the most common sequelae of JIA-associated uveitis and can result in significant visual disability. Risk factors for cataracts include posterior synechiae and longstanding ocular inflammation. Prevention of cataract development is crucial through appropriate control of uveitis. However, not all preventive measures are successful, and further management consisting of medical and surgical techniques is often necessary. Various factors should be taken into consideration when deciding on cataract management, including timing of surgery and placement of an intraocular lens. Continued partnership between pediatric rheumatologists and pediatric ophthalmologists can help ensure favorable visual outcomes.

Timing of uveitis onset in oligoarticular juvenile idiopathic arthritis (JIA) is the main predictor of severe course uveitis

PURPOSE

Aim of the present study was to validate a statistical model to predict a severe course of anterior uveitis (AU) in patients with juvenile idiopathic arthritis (JIA).

METHODS

Consecutive patients with newly diagnosed uveitis have been followed for at least 1 year with a standardized protocol. For each patient, demographic, clinical and laboratory characteristics, including time interval between arthritis and uveitis onset, α(2)-globulins level at arthritis onset, number of uveitis relapses/year, ocular complications and therapy and visual acuity, have reported. The validation procedure included the assessment of sensitivity, specificity and efficiency of previously published statistical model (Zulian et al. J Rheumatol 2002; 29: 2446-2453) in a new inception cohort of patients during a short length follow-up.

RESULTS

Sixty patients with JIA, followed at 14 paediatric rheumatology-ophthalmology centres in Italy, entered the study. The mean age at arthritis onset was 4.4 years (range 1.2-15.8 years), and the mean interval time between arthritis and uveitis onset was 1.8 years (range: 0.0-14.2 years). After the first AU, patients, followed for a mean of 3.2 years, had a mean of 2.9 uveitis relapses. Twenty-two patients (36.7%) presented at least one complication. Using a probability cut-off value = 0.7, the statistical model revealed 80% sensitivity, 58% specificity and 65% efficiency.

CONCLUSION

The time interval between arthritis and uveitis onset resulted as the main predictor of severe course uveitis in JIA. The statistical model was able to predict the development of a severe course in 8 of 10 patients.

Band-shaped keratopathy in Chinese patients with Vogt-Koyanagi-Harada syndrome

PURPOSE

To determine the incidence and characterize the clinical features of band-shaped keratopathy in Chinese patients with Vogt-Koyanagi-Harada (VKH) syndrome.

METHODS

The data of 360 consecutive VKH patients examined from November 2000 to December 2008 were reviewed. The patients were diagnosed with VKH syndrome according to international criteria. The data of VKH patients with band-shaped keratopathy, including age at disease onset, gender, intervals between disease onset and emergence of this complication, other complications, and therapy were collected and analyzed.

RESULTS

Of the 360 VKH patients, 66 patients (132 eyes) visited us at the stage of posterior uveitis or anterior uveal involvement. None of these 132 eyes had band-shaped keratopathy develop. The other 294 VKH patients (587 eyes) visited us at the stage of recurrent, granulomatous, anterior uveitis, and band-shaped keratopathy was observed in 21 eyes of 13 patients (3.6%). Of these 13 patients, there were 6 men and 7 women. Band-shaped keratopathy in 21 eyes was observed from 9 months to 32 years, with a mean of 12.7 years after the first uveitis attack. These patients had been intermittently treated with systemic corticosteroids and occasionally in combination with a transient use of either chlorambucil or azathioprine. All the eyes with band-shaped keratopathy showed recurrent and chronic intraocular inflammation. Complicated cataract, increased intraocular pressure and decreased intraocular pressure were observed in 18, 12, and 5 eyes, respectively. Ocular phthisis was observed in 1 eye. The best-corrected vision of 0.3 or less was observed in 85.1% of the affected eyes.

CONCLUSIONS

Band-shaped keratopathy is a relatively uncommon complication in VKH syndrome and mostly occurs in relatively younger patients with a long course of chronic intraocular inflammation. It was frequently associated with complicated cataract and secondary glaucoma and was a marker for poor visual outcome.

Long-term efficacy of adalimumab in the treatment of uveitis associated with juvenile idiopathic arthritis

Background

The purpose of this study was to investigate the long-term effects of adalimumab, a tumor necrosis factor alpha antagonist, in the treatment of uveitis associated with juvenile idiopathic arthritis.

Methods

Adalimumab was initiated in 94 patients with juvenile idiopathic arthritis to treat active arthritis and/or active associated uveitis. In 18 patients, therapy was discontinued after a short period because of inefficacy or side effects. The activity of uveitis (using Standardized Uveitis Nomenclature [SUN] criteria and clinical examination) and arthritis (number of swollen or active joints) was evaluated at the start and at end of the study.

Results

At the end of the study, uveitis was under good clinical control in two thirds of 54 patients (31% did not need any local treatment and 35% used only 1–2 corticosteroid drops a day), and one third had active uveitis (at least three corticosteroid drops a day). According to SUN criteria, adalimumab treatment for uveitis showed improved activity (a two-fold decrease in uveitis activity) in 28% of patients, with a moderate response in 16 patients, no change in a further 16 patients, and worsening activity (a two-fold increase in uveitis activity) in 13% of patients. The overall proportion of patients with active arthritis decreased. At the beginning of the study, 69% of patients with uveitis had more than two active joints, and at the end of the study only 27% had active joint disease. In 27 patients with juvenile idiopathic arthritis without uveitis on adalimumab, the number of active joints decreased from 93% to 59%. Systemic corticosteroid treatment could be stopped in 22% of patients with uveitis and in 11% of those without uveitis. Most of the patients had received methotrexate, other immunosuppressive therapy, or other biological drugs before initiating adalimumab.

Conclusion

Adalimumab is a valuable option in the treatment of uveitis associated with active juvenile idiopathic arthritis.

Abatacept: a potential therapy in refractory cases of juvenile idiopathic arthritis-associated uveitis

BACKGROUND

Juvenile idiopathic arthritis (JIA) is the most common of all systemic conditions associated with childhood uveitis. Visual impairment has been shown to be as high as 40% of which 10% being blind (6/60 or worse). Due to the lack of well-designed randomized control trials for paediatric uveitis and arthritis there are limited comparative data regarding the efficacy of single or combination treatments. Recently, abatacept was shown to control ocular inflammation in a case of psoriatic arthritis- associated uveitis, seven cases of JIA- associated uveitis and in JIA. We present two cases with JIA-associated uveitis who have responded dramatically to abatacept therapy following unsuccessful therapy with other immunosuppressants. Control of arthritis still represents a challenge with this treatment.

METHODS

Prospective review of two patients with refractory JIA- associated uveitis not responding to maximum conventional treatment. Patients were regularly reviewed in the ophthalmology and rheumatology clinics. Assessment of their ocular condition was characterized according to the Standardization of Uveitis Nomenclature (SUN) group.

RESULTS

In case 1, ocular inflammation was brought under control after repeated abatacept infusions. Case 2 showed complete resolution of cystoids macular edema CME and improvement of 5 Snellen's lines in best corrected visual acuity. After 9 months, the ocular condition of both patients remains in remission with steroid sparing. Joint disease was brought to clinical remission in case 2, but not in case 1.

CONCLUSIONS

Abatacept is a promising alternative treatment in refractory cases of JIA uveitis but may not be as successful in controlling joint disease. Larger series with long term follow up of biological therapies in paediatric uveitis are essential to assess the efficacy and cost effectiveness.

Male gender as a risk factor for complications in uveitis associated with juvenile idiopathic arthritis

PURPOSE

To analyze the role of baseline factors in long-term development of ocular complications in uveitis associated with juvenile idiopathic arthritis (JIA).

DESIGN

Retrospective nonrandomized interventional case series.

METHODS

Data of 117 affected eyes (65 patients) with JIA-associated uveitis with a minimum follow-up of 1 year were obtained. Development of complications was analyzed univariately and multivariately in relation to gender, age of onset of uveitis (<7 years or >7 years), and initial manifestation of JIA (as uveitis or as arthritis).

RESULTS

Female-to-male ratio was 3:1 and follow-up for uveitis ranged from 1.1 to 27.5 years (median 7.6 years). Time interval between arthritis and uveitis was shorter in boys (median 0.3 year) than in girls (median 1.0 year) (P < .01). At 5 years of follow-up boys suffered more frequently from cystoid macular edema (CME) (50% vs 4%; P < .01) and papillitis (31% vs 2%; P < .01), and needed more cataract surgery (59% vs 32%; P = .02). At 5 years of follow-up children with initial uveitis had more posterior synechiae, band keratopathy, and CME (all P <or= .02), but less glaucoma (P = .03). In multivariate analysis male gender appeared to be independently associated with cataract surgery (adjusted hazard ratio [HR] = 4.33; P < .01), CME (HR = 4.59; P = .01), and papillitis (HR = 4.10; P = .01). Development of posterior synechiae was independently associated with initial uveitis (HR = 3.21; P < .01).

CONCLUSIONS

Male gender and uveitis as initial manifestation of JIA were independently associated with a complicated course of JIA-associated uveitis. Age of onset of JIA-associated uveitis does not seem to have independent prognostic value for the course of this ocular disorder.

Risk of cataract development among children with juvenile idiopathic arthritis-related uveitis treated with topical corticosteroids

PURPOSE

We sought to investigate the risk of cataract development among patients with juvenile idiopathic arthritis (JIA)-associated uveitis treated with topical corticosteroids.

DESIGN

Retrospective cohort study.

PARTICIPANTS

We included 75 patients with JIA-associated uveitis observed from July 1984 through August 2005 at a single academic center.

METHODS

Clinical data on these patients were collected by chart review and were analyzed.

MAIN OUTCOME MEASURES

Incidence of new-onset cataract. Risk factors for cataract development were assessed with attention paid to the use of topical corticosteroids.

RESULTS

Over a median follow-up of 4 years, the incidence of new-onset cataract was 0.04/eye-year (EY; 95% confidence interval [CI], 0.02-0.09). Of the 60 eyes in 40 patients who received topical corticosteroid therapy, there was a dose-dependent increase in the rate of cataract development among eyes receiving topical corticosteroids. The incidence of cataract was 0.01/EY for eyes treated with < or = 3 drops daily and 0.16/EY (P = 0.0006 for log-rank test) for eyes treated with >3 drops daily. Among eyes receiving < or = 2 drops daily, the incidence of cataract was 0/EY (95% CI [1 sided], 0.03/EY). Presence of posterior synechiae, active uveitis, and use of topical corticosteroids at presentation were significantly associated with cataract development after controlling for confounding variables. Use of topical corticosteroids was associated with cataract formation independent of uveitis activity. Using longitudinal data analysis and controlling for duration of uveitis, presence and degree of active uveitis, and concomitant use of other forms of corticosteroids in a time-updated fashion, treatment with < or = 3 drops daily of topical corticosteroid was associated with an 87% lower risk of cataract formation compared with eyes treated with >3 drops daily (relative risk, 0.13; 95% CI, 0.02-0.69; P = 0.02).

CONCLUSIONS

In our cohort, topical corticosteroid use was associated with an increased risk of cataract formation independent of active uveitis or presence of posterior synechiae. However, chronic use of topical corticosteroids dosed at < or = 3 drops daily seemed to be associated with a lower risk of cataract development relative to eyes receiving higher doses over follow-up in the setting of suppressed uveitis.

Clinical manifestations and treatment of the pediatric rheumatoid patient

The management goal of juvenile rheumatoid arthritis (JRA) is to achieve early diagnosis and treatment so that arthritis can be resolved at an early stage, which avoids long-term damage and provides a good outcome of the affected inflammatory joints. This article describes presentation, classification, evaluation, and treatment of JRA as it relates to the foot and ankle. Because the course of JRA is complex and the optimal management is highly variable in each patient, this article can only offer recommendations. Actual treatment should be individualized to meet the conditions of each patient.

Long-term follow-up of patients with uveitis associated with juvenile idiopathic arthritis: a cohort study

PURPOSE

To analyze the clinical and visual outcome of 55 consecutive patients with juvenile idiopathic arthritis (JIA)-associated uveitis examined 7 and 24 years after the onset of the eye disease.

METHODS

A retrospective study.

RESULTS

Fifty-five out of 350 patients with JIA developed uveitis (15.7%). Forty-six (84%) of these had oligoarthritis, 6 (11%) had polyarthritis, and 3(5%) had systemic disease. Cataract was present in 42% at 7 years and in 51% at 24 years. Uveitic glaucoma was present in 5% at 7 years and in 22% at 24 years. After 24 years, 27 patients (49%) still had active uveitis.

CONCLUSIONS

In half of these patients the uveitis was still active after 24 years of eye disease. In the group of patients with active disease, cataract and secondary glaucoma increased significantly between years 7 and 24 of disease.

An evaluation of dry eye symptoms and signs in a cohort of children with juvenile idiopathic arthritis

OBJECTIVE

To determine the prevalence of dry eye symptoms and signs in children with juvenile idiopathic arthritis (JIA).

PATIENTS AND METHODS

A total of 192 children with JIA: 48 oligo-, 39 extended oligo-, 79 polyarthritis, and 26 with other types of arthritis (eight juvenile spondyloarthritis, five juvenile psoriatic arthritis, three mixed connective tissue diseases, two systemic onset arthritis, and eight undetermined arthritis) were interviewed for dry eye symptoms and tested with Schirmer test with anesthetic. Two thirds of the patients were female and the mean age of the patients was 13.1 years (range 10-16) and the mean duration of arthritis was six years (SD 4, 4). Thirty-one percent of the patients had a history of uveitis. Dry eye was defined as Schirmer test score </= 5 mm in five minutes. The type of arthritis, a history of uveitis, and the ocular and systemic medication used were evaluated for their correlation with dry eye symptoms and signs by using chi-square tests and the Mann-Whitney Monte Carlo analysis.

RESULTS

Altogether 17% of this cohort had decreased basal tear secretion. The most common symptoms of dry eye were discharge secretion, itching, and watering. The intensity of symptoms and signs did not correlate. The type of arthritis, a history or presence of uveitis, and the medication used did not correlate with the occurrence of dry eyes.

CONCLUSION

Dry eye symptoms and signs are common in JIA, and Schirmer test with anesthetic is a useful tool in evaluating these patients.

Topical treatment of uveitis resulting in adrenal insufficiency

The adverse effects of corticosteroids are well-known and occur more frequently when corticosteroids are used perorally or intravenously. The management of uveitis, which normally consists of topical corticosteroids and mydriates, can be challenging. We report a case in which continuous use of topical corticosteroids resulted in adrenal insufficiency and obesity.

CONCLUSION

When topical corticosteroids are used over longer periods, hypophysis-pituitary-adrenal (HPA) function should be carefully monitored.

Granulomatous inflammation in juvenile idiopathic arthritis-associated uveitis

PURPOSE

The uveitis that is associated with juvenile idiopathic arthritis (JIA) has typically been described as nongranulomatous. This study reports the prevalence of granulomatous disease in a population with JIA-associated uveitis.

METHODS

We conducted a retrospective analysis of all patients with JIA-associated uveitis seen between 1973 and 2006 at a hospital-based uveitis service. Patients with uveitis were included if they were diagnosed with JIA by a specialist and experienced at least 6 weeks of arthritis starting before the age of 16 years. Granulomatous disease was defined as Busacca or angle nodules, mutton-fat keratic precipitates (KP), or hyalinized "ghost" KPs. Statistical tests were performed to seek associations between granulomatous disease and various clinical factors.

RESULTS

Seventy-one patients with JIA-associated uveitis were included. Granulomatous uveitis was observed in 28% of the population, with 7% exhibiting mutton-fat KP, and 21% "ghost" KP. There was no association between the presence of granulomatous disease and age of arthritis onset, age of uveitis onset, sex, antinuclear antibody status, or whether the arthritis was pauciarticular or polyarticular. In this population, 67% of black patients had granulomatous disease compared with 25% of nonblack patients (p < 0.05), and 24% of white patients showed granulomatous disease compared with 56% of nonwhite patients (p = 0.11).

CONCLUSIONS

Granulomatous disease is more common in JIA-associated uveitis than previously thought and may be more common in black patients. Although it is necessary to exclude other forms of granulomatous uveitis, such as sarcoidosis, the presence of granulomatous uveitis is not inconsistent with a diagnosis of JIA-associated uveitis.

Intraocular inflammation: its causes and investigations

Intraocular inflammation, or uveitis, incorporates a diverse group of infectious and immune-mediated disorders. In addition, some conditions masquerade as uveitis. However, classifying uveitis according to anatomic location in adult and pediatric populations, and appreciating the effect of immune status and regional differences, refines the list of potential causes. In this way, a select few investigations can be performed, rather than a nondirected battery of tests.

Tumor necrosis factor antagonists: preliminary evidence for an emerging approach in the treatment of ocular inflammation

The anti-tumor necrosis factor (TNF) monoclonal antibody infliximab and the soluble TNF receptor etanercept inhibit the pleiotropic actions of TNF and are widely used for the treatment of rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), spondyloarthropathies (SpA), Crohn's disease, and psoriasis with an acceptable safety profile. A pathogenetic role of TNF in ocular inflammatory conditions has recently emerged from small trials reporting preliminary results on the efficacy of these agents in patients with noninfectious uveitis, regardless of the origin of the disease. The authors review the published experience, derived mostly from investigator-sponsored trials and uncontrolled case series, on the use of TNF antagonists in approximately 280 patients with various ocular conditions who were inadequately controlled on currently available therapy. These reports suggest that TNF antagonists, mainly infliximab, which may have better efficacy than etanercept, are useful in the treatment of ocular inflammation associated with Adamantiades-Behçet's disease, RA, JIA, SpA, Crohn's, sarcoidosis, and Graves' disease ophthalmopathy. Infliximab was also beneficial in small numbers of patients with idiopathic uveitis or scleritis, birdshot retinochoroiditis, uveitic and diabetic cystoid macular edema, and age-related macular degeneration. The currently available data are nonrandomized and thus preliminary, providing the foundation and justification for randomized trials to assess efficacy and safety. Until such results are available, knowledge regarding the use of anti-TNF regimens in ophthalmology is incomplete. However, the preliminary evidence points to a growing optimism for targeting TNF in patients with ocular inflammation.
