The risk of uveitis in patients with JIA receiving etanercept: the challenges of analysing real-world data

Incidence of Uveitis in Patients With Axial Spondylarthritis Treated With Biologics or Targeted Synthetics: A Systematic Review and Network Meta-Analysis

OBJECTIVE

Anterior uveitis is a common extra-articular manifestation of axial spondyloarthritis (AxSpA). We set to evaluate the risk of anterior uveitis (AU) with biologics and synthetic disease-modifying drugs in AxSpA.

METHODS

We conducted a systematic review and meta-analysis to identify phase II/III double-blinded randomized controlled trials of anti-tumor necrosis factor (TNF) monoclonal antibodies (mAb), anti-interleukin-17 (anti-IL-17), and Janus kinase inhibitors (JAKi) in AxSpA. Patient-exposure years (PEY) were calculated using the per-protocol approach. Incidence rate (IR) of AU/100 person-years were calculated by treatment group using the random effects approach. Network meta-analysis (NMA) was used to estimate risk of AU in treatment groups, expressed as IR ratios (IRRs). Bias was assessed using the Cochrane Risk of Bias-2 tool.

RESULTS

Forty-four trials were included: 17 anti-TNF mAb (1,004 PEY), 9 etanercept (180 PEY), 13 anti-IL-17 (1,834 PEY), and 6 JAKi (331 PEY). The IR of AU were as follows for anti-TNF mAb: 4.1, 95% confidence interval (CI) 0-8.5; etanercept: 5.4, 95% CI 0-16.0; anti-IL-17: 2.8, 95% CI 1.6-4.1; JAKi: 1.5, 95% CI 0.0-3.0; and placebo: 10.8, 95% CI 7.4-14.1. In NMA, IRRs of treatments compared with placebo were as follows for anti-TNF mAb: 0.32, 95% CI 0.10-1.04; etanercept 0.42, 95% CI 0.08-2.38; anti-IL-17: 0.43, 95% CI 0.19-0.98; and JAKi: 0.32, 95% CI 0.06-1.67. Comparisons between anti-TNF mAb, anti-IL-17, and JAKi did not demonstrate any significant difference in AU risk. Using the surface under the cumulative ranking curve approach to rank AU risk, anti-TNF mAbs were associated with the lowest risk followed by JAKi, anti-IL-17, and etanercept. All treatments were ranked superior to placebo.

CONCLUSION

Anti-TNF mAbs, JAKi, and anti-IL-17 appear protective against AU events in individuals with AxSpA, with no significant differences in risk of AU between treatments.

Etanercept-associated episcleritis: a pediatric case report of a paradoxical adverse reaction and review of the literature

Scleritis is an inflammation of the episcleral and scleral tissues, characterized by injection in both superficial and deep episcleral vessels. When only episcleral tissue is involved, it is referred to as episcleritis. Episcleritis is mainly idiopathic but may be secondary to an underlying rheumatologic disease. Despite being rare, drug-associated episcleritis and scleritis should also be included in the differential diagnosis. Tumor necrosis factor-alpha (TNF-α) inhibitors are generally well-tolerated, but etanercept, in particular, has the potential to cause paradoxical adverse reactions including ocular inflammations, such as uveitis, scleritis, and ocular myositis. Etanercept differs in its mechanism of action from other TNF-α inhibitors as it acts as a decoy receptor, and this may partly explain the more frequently reported etanercept-associated ocular inflammation. Etanercept may also be ineffective in preventing ocular inflammation. However, the dechallenge and rechallenge phenomena have proven there is a causative link between etanercept and new-onset ocular inflammation. We report a case of a 15-year-old boy with enthesitis-related arthritis and familial Mediterranean fever who presented with episcleritis and blepharitis while receiving etanercept treatment and subsequently showed dechallenge and rechallenge reactions. Therefore, physicians should also be aware that episcleritis should be considered a paradoxical adverse reaction to etanercept and can occur in pediatric patients. We also reviewed the English literature to provide an overview and evaluate intervention options.

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

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

Uveitis Associated with Monogenic Autoinflammatory Syndromes in Children

Monogenic autoinflammatory syndromes (MAISs), are caused by pathogenic genetic variants in the innate immune system, leading to dysregulation and aberrant inflammasome activation spontaneously or with minimal triggering. The diagnosis and treatment of MAISs can be intricate, relying on an increased recognition of potential differential diagnoses. This review examines the clinical features of MAIS, with a special focus on uveitis. It also evaluates treatment options and assesses the effects of activating molecular and cytokine pathways.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

Challenges and management of childhood non-infectious chronic uveitis

INTRODUCTION

Childhood uveitis is a sight-threatening condition, because if not properly recognized and treated can lead to several ocular complications and blindness. It represents a real challenge not only from an etiologic/diagnostic point of view, but also for management and therapy.

AREAS COVERED

In this review we will discuss the main etiologies, the diagnostic approach, risk factors associated to childhood non-infectious uveitis (cNIU), and the difficulties in eye examination in childhood. Moreover, we will discuss the treatment of cNIU in term of therapeutic choice, timing of initiation and withdrawal.

EXPERT OPINION

Identification of specific diagnosis is mandatory to prevent severe complications, thus a thorough differential diagnosis is essential. Pediatric eye examination may be extremely challenging due to the scarce collaboration, but novel techniques and biomarkers will help in identify low grade of inflammation, eventually modify long-term outcomes. Once identified the appropriate diagnosis, recognition of children who may benefit of a systemic treatment is crucial. What, When and how long are the key questions to address in this field. Current evidence and future results of ongoing clinical trials will help in driving treatment. A proper ocular screening, not only in the context of systemic disease, should be discussed by experts.

Comparison of Uveitis Incidence by Medication in Juvenile Idiopathic Arthritis and Implications for Screening

PURPOSE

To determine uveitis incidence in juvenile idiopathic arthritis (JIA) patients treated with disease-modifying antirheumatic drugs (DMARD) medications, and to evaluate uveitis risk-stratification protocols.

DESIGN

Retrospective clinical cohort study.

METHODS

Medical records of patients with JIA seen by ophthalmology at a single institution from April 2014 to April 2022 and ≥18 months' follow-up were reviewed. Exclusion criteria included uveitis history prior to study period, Still disease, or <18 months' follow-up. Patient characteristics, medications, and uveitis status were recorded. Factors associated with uveitis development were analyzed and statistically significant metrics used to determine empiric risk-stratification criteria. These criteria and American College of Rheumatology (ACR) risk-stratification guidelines were applied retroactively to determine predictive power.

RESULTS

One hundred eighty-four patients met inclusion criteria and were included. Twenty-one new cases of uveitis developed during the study period. There were no statistically significant differences between no DMARD treatment, methotrexate (MTX), and etanercept (ETA) groups in uveitis incidence, whereas the adalimumab (ADA) and other biologics groups had no uveitis cases. Under the empirically determined criteria, the ratio of uveitis incidence between high- and low-risk groups was 8.21 (2.68-33.55; P < .0001), whereas it was 1.90 (0.72-4.93; P = .15) under the ACR criteria.

CONCLUSION

Patients on MTX, ETA, and no DMARD treatment were comparable in JIA-associated uveitis incidence, whereas there were no new cases with ADA or other biologics. Further, we found increased predictive power in the empiric criteria in comparison to current ACR risk stratification.

Indications and effects of biological agents in the treatment of noninfectious uveitis

Noninfectious uveitis is a common blinding eye disease, and an autoimmune response is involved in its pathogenesis. Biological agents have gradually been introduced into the treatment of noninfectious uveitis. The authors reviewed the clinical application and side effects of different biological agents on noninfectious uveitis. Biological agents that target TNF-α are widely used in the clinic. Other biological agents, such as IL-6- and IL-1-neutralizing antibodies, are used in patients who do not respond to TNF inhibitors. The efficacy of IL-17 neutralizing antibodies in noninfectious uveitis is controversial. Biological agents targeting T cells and signaling pathways provide new drug options for treatment of noninfectious uveitis. However, it cannot be ignored that these biological agents have side effects, such as increasing risk of infection.

Uveitis in Children and Adolescents

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

Risk of Liver Injury Associated with Intravenous Lipid Emulsions: A Prescription Sequence Symmetry Analysis

Aims: To determine the risk of liver injury associated with the use of different intravenous lipid emulsions (LEs) in large populations in a real-world setting in China. Methods: A prescription sequence symmetry analysis was performed using data from 2015 Chinese Basic Health Insurance for Urban Employees. Patients newly prescribed both intravenous LEs and hepatic protectors within time windows of 7, 14, 28, 42, and 60 days of each other were included. The washout period was set to one month according to the waiting-time distribution. After adjusting prescribing time trends, we quantify the deviation from symmetry of patients initiating LEs first and those initiating hepatic protectors first, by calculating adjusted sequence ratios (ASRs) and relevant 95% confidence intervals. Analyses were further stratified by age, gender, and different generations of LEs developed. Results: In total, 416, 997, 1,697, 2,072, and 2,342 patients filled their first prescriptions with both drugs within 7, 14, 28, 42, and 60 days, respectively. Significantly increased risks of liver injury were found across all time windows, and the strongest effect was observed in the first 2 weeks [ASR 6.97 (5.77-8.42) ∼ 7.87 (6.04-10.61)] in overall patients. In subgroup analyses, female gender, age more than 60 years, and soybean oil-based and alternative-LEs showed higher ASRs in almost all time windows. Specially, a lower risk for liver injury was observed in the first 14 days following FO-LEs administration (ASR, 3.42; 95% CI, 0.81-14.47), but the risk started to rise in longer time windows. Conclusion: A strong association was found between LEs use and liver injury through prescription sequence symmetry analysis in a real-world setting, which aligns with trial evidence and clinical experience. Differences revealed in the risks of liver injury among various LEs need further evaluation.
