Abstract
Non-infectious uveitis (NIU) is a disorder with various etiologies and is characterized by eye inflammation, mainly affecting people of working age. An accurate diagnosis of NIU is crucial for appropriate therapy. The aim of therapy is to improve vision, relieve ocular inflammation, prevent relapse, and avoid treatment side effects. At present, corticosteroids are the mainstay of topical or systemic therapy. However, repeated injections are required for the treatment of chronic NIU. Recently, new drug delivery systems that may ensure intraocular delivery of therapeutic drug levels have been highlighted. Furthermore, with the development of immunosuppressants and biologics, specific therapies can be selected based on the needs of each patient. Immunosuppressants used in the treatment of NIU include calcineurin inhibitors and antimetabolites. However, systemic immunosuppressive therapy itself is associated with adverse effects due to the inhibition of immune function. In patients with refractory NIU or those who cannot tolerate corticosteroids and immunosuppressors, biologics have emerged as alternative treatments. Thus, to improve the prognosis of patients with NIU, NIU should be managed with different drugs according to the response to treatment and possible side effects.

Abstract
The uveitides are a heterogeneous group of diseases characterized by inflammation inside the eye. The uveitides are classified as infectious or non-infectious. The non-infectious uveitides, which are presumed to be immune mediated, can be further divided into those that are associated with a known systemic disease and those that are eye limited,-ie, not associated with a systemic disease. The ophthalmologist identifies the specific uveitic entity by medical history, clinical examination, and ocular imaging, as well as supplemental laboratory testing, if indicated. Treatment of the infectious uveitides is tailored to the particular infectious organism and may include regional and/or systemic medication. First line treatment for non-infectious uveitides is corticosteroids that can be administered topically, as regional injections or surgical implants, or systemically. Systemic immunosuppressive therapy is used in patients with severe disease who cannot tolerate corticosteroids, require chronic corticosteroids at >7.5 mg/day prednisone, or in whom the disease is known to respond better to immunosuppression. Management of many of these diseases is optimized by coordination between the ophthalmologist and rheumatologist or internist.

Changing evidence over time: updated meta-analysis regarding anti-TNF efficacy in childhood chronic uveitis. Rheumatology (Oxford) 2020; 60:568-587. [DOI: 10.1093/rheumatology/keaa595] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2020] [Revised: 07/19/2020] [Accepted: 07/31/2020] [Indexed: 12/14/2022] Open
Abstract
Abstract
Objective
To summarize evidence regarding efficacy of anti-TNFα in childhood chronic uveitis, refractory to common DMARDs.
Methods
An updated systematic search was conducted between November 2012 and January 2020. Studies investigating the efficacy of anti-TNFα therapy, in children of ages <16 years, as the first biologic treatment for childhood chronic uveitis, refractory to topical and/or systemic steroid and at least one DMARD were eligible for inclusion. The primary outcome measure was the improvement of intraocular inflammation according to Standardization of Uveitis Nomenclature Working Group criteria. A combined estimate of the proportion of children responding to etanercept (ETA), infliximab (INF), and adalimumab (ADA) was determined.
Results
We identified 1677 articles of which 37 articles were eligible. Three were randomized controlled trials, one on ETA and two on ADA, and were excluded from pooled analysis. From the observational studies, a total of 487 children were identified: 226 received ADA, 213 INF and 48 ETA. The proportion of responding children was 86% (95% CI: 76%, 95%) for ADA, 68% (95% CI: 50%, 85%) for INF and 36% (95% CI: 9%, 67%) for ETA. Pooled analysis showed clear differences (χ2 = 32.2, P < 0.0001): ADA and INF were both significantly superior to ETA (χ2 = 26.8, P < 0.0001, and χ2 = 7.41, P < 0.006, respectively), ADA significantly superior to INF (χ2 = 13.4, P < 0.0002).
Conclusion
This meta-analysis, consistent with recent randomized controlled trial data, suggests the efficacy of ADA and INF in childhood chronic uveitis treatment. However, ADA results were superior to those of INF in this clinical setting.

Quiescence and Subsequent Anterior Chamber Inflammation in Adalimumab-treated Pediatric Noninfectious Uveitis. KOREAN JOURNAL OF OPHTHALMOLOGY 2020; 34:274-280. [PMID: 32783419 PMCID: PMC7419232 DOI: 10.3341/kjo.2020.0005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2020] [Revised: 02/28/2020] [Accepted: 03/23/2020] [Indexed: 11/23/2022] Open
Abstract
PURPOSE To evaluate the effect of adalimumab in pediatric uveitis and subsequent changes in anterior chamber inflammation following the inactivation of uveitis. METHODS In this retrospective study, patients with noninfectious uveitis younger than 18 years of age who were treated with adalimumab for more than 12 months were included. The rate of complete suppression and the relapse in anterior chamber inflammation following the initiation of adalimumab therapy were evaluated using anterior chamber cell score and laser flare photometry (LFP) values, if available. Changes in visual acuity and the sparing effect of topical steroid agents were also evaluated. RESULTS Among 22 eyes of 12 pediatric uveitis patients enrolled, 13 eyes were associated with juvenile idiopathic arthritis and nine eyes had idiopathic uveitis. The mean ± standard deviation age was 10.2 ± 3.6 years. Types of uveitis included anterior uveitis (n = 17) and panuveitis (n = 5). Quiescence was observed in 14 eyes (63.6%) at 3 months and in 21 eyes (95.5%) at 12 months after initiation, respectively. After achieving inactive uveitis, uveitis relapsed in two eyes at 6 months, even with adalimumab treatment. In 11 eyes, anterior chamber showed 0.5+ cell scores during the rest of the follow-up period and one of those eyes met the criteria for the relapse based on LFP values. The dosage of topical steroids decreased significantly at 3, 9, and 12 months after the initiation of therapy (p ≤ 0.05). Visual acuity did not show improvement. There were no severe adverse effects of anti-tumor necrosis factor-α treatment reported. CONCLUSIONS In this study, adalimumab achieved a quiescent state in most eyes with pediatric noninfectious uveitis for 12 months with a relapse rate of 9.5%. LFP values together with the anterior chamber cell score can be utilized to monitor the improvement or relapse in anterior chamber inflammation in pediatric noninfectious uveitis.

The use of biologic agents in the management of uveitis. Intern Med J 2020; 49:1352-1363. [PMID: 30582273 DOI: 10.1111/imj.14215] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2018] [Revised: 12/08/2018] [Accepted: 12/19/2018] [Indexed: 12/14/2022]
Abstract
The uveitides are a heterogenous group of ocular inflammatory disorders that account for the third highest cause of blindness worldwide, responsible for 5-10% of visual impairment globally. Up to 35% of patients with uveitis can suffer significant vision loss. To prevent irreversible structural damage and blindness, it is important that the diagnosis and commencement of appropriate therapy occurs promptly. Management includes topical and systemic corticosteroid therapy and conventional immunomodulatory agents, including methotrexate, azathioprine, mycophenolate mofetil and cyclosporin. Significant progress has been made in the past decade in our understanding of the immunopathological pathways that drive intraocular inflammation, allowing the development of targeted therapy with biologic agents. These include TNF-α inhibitors, such as infliximab, adalimumab and etanercept; interleukin blockers, such as tocilizumab and daclizumab; and other targeted therapies, such as rituximab and abatacept. The efficacy of these agents has been studied in cases of severe uveitis that are refractory to conventional immunomodulatory agents and provide exciting results that have revolutionised uveitis management. Though the biologic era has provided a large armamentarium to treat uveitis, ongoing challenges and cases of recalcitrant uveitis remain, posing a challenge to internal medicine physicians. This comprehensive review aims to construct an updated summary on the existing evidence pertaining to the use of biologic agents in the treatment of uveitis. Methods include a systematic search for studies between 2000 and 2018 using PubMed, EMBASE, Ovid MEDLINE and Cochrane libraries.

New therapies in development for the management of non-infectious uveitis: A review. Clin Exp Ophthalmol 2020; 47:396-417.

Abstract
Uveitis is a spectrum of inflammatory disorders characterized by ocular inflammation and is one of the leading causes of preventable visual loss. The main aim of the treatment of uveitis is to control the inflammation, prevent recurrences of the disease and preserve vision while minimizing the adverse effects associated with the therapeutic agents. Initial management of uveitis relies heavily on the use of corticosteroids. However, monotherapy with high-dose corticosteroids is associated with side effects and cannot be maintained long term. Therefore, steroid-sparing agents are needed to decrease the burden of steroid therapy. Currently, the therapeutic approach for non-infectious uveitis (NIU) consists of a step-ladder strategy with the first-line option being corticosteroids in various formulations followed by the use of first-, second- and third-line agents in cases with suboptimal steroid response. Unfortunately, the agents currently at our disposal have limitations such as having a narrow therapeutic window along with their own individual potential side-effect profiles. Therefore, research has been targeted to identify newer drugs as well as new uses for older drugs that target specific pathways in the inflammatory response. Such efforts are made in order to provide targeted and safer therapy with reduced side effects and greater efficacy. Several specially designed molecular antibodies are currently in various phases of investigations that can potentially halt the inflammation in patients with NIU. In the review, we have provided a comprehensive overview of the current and upcoming therapeutic options for patients with NIU.

Abstract
Introduction: The treatment strategies for noninfectious uveitis (NIU) aim to achieve disease remission, prevention of recurrences, and preserving vision, while minimizing the side effects associated with the therapies used.Areas covered: The index review aims to provide a detailed overview of the adverse events and safety parameters associated with the systemic therapies for the management of the NIU.Expert opinion: Despite being the cornerstone of management of acute cases of NIU, long-term corticosteroid use is associated with multi-system side effects, requiring the use of steroid-sparing agents. Adalimumab was recently approved by the FDA for the management of NIU based on the results of VISUAL studies. Similarly, newer drugs targeting various aspects of the inflammatory cascade are being developed. However, until we completely understand the molecular pathways of the inflammatory diseases, the therapeutic profile of these newer agents needs to be broad enough to suppress inflammatory cascade and narrow enough to spare normal cellular processes. Another strategy that has shown some potential in decreasing the systemic side effects is to provide local drug delivery. Therefore, the future of management of NIU is very bright with many novel therapeutic agents and strategies of drug delivery on the horizon.

Abstract
PURPOSE OF REVIEW There is mounting evidence supporting the use of biologic therapeutics for the management of noninfectious uveitis (NIU). This review highlights: biologics with documented efficacy in NIU; agents with ongoing evaluation for efficacy in uveitis; and therapeutics for which investigation for efficacy in NIU is warranted. RECENT FINDINGS The tumor necrosis factor-alpha (TNF-α) inhibitor adalimumab has recently gained approval by the Food and Drug Administration for the treatment of noninfectious intermediate, posterior, and panuveitis. There is mounting evidence supporting the use of tocilizumab and rituximab in NIU. There is developing interest in evaluating the interleukin (IL)-23 inhibitors for efficacy in NIU. SUMMARY The TNF-α inhibitors adalimumab and infliximab have the greatest body of data supporting their use in NIU. These agents are considered second-line therapy for most forms of NIU but may be considered first-line therapy for uveitis associated with Behçet's disease and juvenile idiopathic arthritis. The B-cell inhibitor rituximab and the IL-6 inhibitor tocilizumab also have documented efficacy in NIU. Tocilizumab and interferon therapy may be particularly efficacious in the management of uveitic macular edema. The IL-23 inhibitors and janus kinase inhibitors are agents whose efficacy in NIU will likely be determined in the near future.

Update of the evidence based, interdisciplinary guideline for anti-inflammatory treatment of uveitis associated with juvenile idiopathic arthritis. Semin Arthritis Rheum 2018; 49:43-55. [PMID: 30595409 DOI: 10.1016/j.semarthrit.2018.11.004] [Citation(s) in RCA: 45] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2018] [Revised: 11/27/2018] [Accepted: 11/29/2018] [Indexed: 12/17/2022]
Abstract
BACKGROUND Uveitis in juvenile idiopathic arthritis (JIAU) is frequently associated with the development of complications and visual loss. Topical corticosteroids are the first line therapy, and disease modifying anti-rheumatic drugs (DMARDs) are commonly used. However, treatment has not been standardized. METHODS Interdisciplinary guideline were developed with representatives from the German Ophthalmological Society, Society for Paediatric Rheumatology, Professional Association of Ophthalmologists, German Society for Rheumatology, parents' group, moderated by the Association of the Scientific Medical Societies in Germany. A systematic literature analysis in MEDLINE was performed, evidence and recommendations were graded, an algorithm for anti-inflammatory treatment and final statements were discussed in a consensus meeting (Nominal Group Technique), a preliminary draft was fine-tuned and discussed thereafter by all participants (Delphi procedure). RESULTS Consensus was reached on recommendations, including a standardized treatment strategy according to uveitis severity in the individual patient. Thus, methotrexate shall be introduced for uveitis not responding to low-dose (≤ 2 applications/day) topical corticosteroids, and a TNFalpha antibody (preferably adalimumab) used, if uveitis inactivity is not achieved. In very severe active uveitis with uveitis-related deterioration of vision, systemic corticosteroids should be considered for bridging until DMARDs take effect. If TNFalpha antibodies fail to take effect or lose effect, another biological should be selected (tocilizumab, abatacept or rituximab). De-escalation of DMARDs should be preceded by a period of ≥ 2 years of uveitis inactivity. CONCLUSIONS An interdisciplinary, evidence-based treatment guideline for JIAU is presented.

Abstract
INTRODUCTION Uveitis encompasses a wide variety of sight-threatening diseases characterized by intraocular inflammation. It is often classified as infectious and non-infectious uveitis. Unlike infectious uveitis, a distinct infectious agent cannot be identified in non-infectious uveitis and disease origin is usually autoimmune, drug related, or idiopathic. THE ISSUE AT HAND Non-infectious uveitis can often have a relapsing-remitting course, making it difficult to treat, and poses a significant challenge to ophthalmologists. The autoimmune nature of non-infectious uveitis warrants the use of anti-inflammatory and immunomodulatory agents for disease control. However, a subset of patients has persistent or recurrent ocular inflammation despite appropriate treatment, stressing the need for newer therapies aimed at more specific inflammatory targets such as tumour necrosis factor (TNF) alpha agents, anti-interleukin agents, and anti-interleukin receptor agents. OBJECTIVES This article discusses the various medical options available for the treatment of non-infectious uveitis in the light of the most recent evidence. CONCLUSION Successful management of non-infectious uveitis requires the clinician carefully balance advantages and disadvantages of each new and old therapy while considering individual circumstances. Counselling regarding the benefits and complications of each therapy can help patients make an informed choice.

Abstract
INTRODUCTION Anti-TNF therapy has dramatically changed how we manage rheumatoid arthritis. There are many similarities among the five approved agents but also some important differences. Rheumatologists have 5 different options to choose from when they are ready to commence anti-TNF therapy. Although all block the TNF cytokine, there are important critical differences among them that affect their safety profile and clinical utility in certain scenarios. Unfortunately, there are no head to head trials to compare the different anti-TNF agents and none appear to be in the horizon. Areas covered: This article reviews the various clinical situations where it may be important to use a particular anti-TNF agent. The authors also give their expert opinion and future perspectives on the area. Expert opinion: Although there are many similarities among the five different TNFi that are clinically available, there are important clinical niches, where the limited data that are available, that clearly support the preferential use of a particular agent or class of agents. Assays or tests that allow us to find the 'sweet spot' of TNF inhibition at the level of each patient are long overdue.

Abstract
Objectives This study aims to evaluate the efficacy of adalimumab as a first line biologic agent in specific subtypes of juvenile idiopathic arthritis (JIA) patients with associated uveitis. Patients and methods We retrospectively analyzed the data of 11 JIA patients (8 males, 3 females; mean age 14.5 years; range 9 to 18 years) with associated uveitis treated with biologic therapy. All patients were diagnosed as oligoarticular/extended oligoarticular or enthesitis-related JIA subtypes, treated with methotrexate, and had active or previous history of uveitis for which adalimumab was prescribed. We tested all patients for anti-nuclear antibody presence and human leukocyte antigen genotype. We assessed disease activity and therapy efficacy by American College of Rheumatology 50%, 70%, and 100% improvement criteria. We evaluated uveitis activity by slit-lamp biomicroscopy and recorded adverse events. Results Of the JIA patients, three (27.27%) had oligoarticular/extended oligoarticular JIA and eight (72.73%) had enthesitis-related arthritis. Anti-nuclear antibody positivity was present in 27.27% (all females) while human leukocyte antigen-B51 was determined in 62.5% and human leukocyte antigen-B27 in 12.5% of patients. Mean uveitis duration before adalimumab introduction was 12.3 months. After two years of follow-up, there were no relapses of uveitis and visual acuity was stable while on adalimumab and methotrexate treatment. All patient were gradually tapered and discontinued treatment with topical steroids. Disease activity improved and seven patients (63.64%) achieved American College of Rheumatology 100% response rate (attained remission), while four patients (36.36%) achieved American College of Rheumatology 70% response rate. Conclusion Anti-nuclear antibody positivity with oligoarticular/extended oligoarticular and enthesitis-related arthritis JIA subtypes, which are known for their high risk to develop uveitis, may benefit from adalimumab as a first line anti-tumor necrosis factor agent.

Abstract
Uveitis may exist as a clinical manifestation of an underlying systemic disease or may represent an idiopathic entity, sometimes with a very characteristic pattern. Different forms of uveitis have been defined on the basis of three important variables: chronicity, anatomic location, and underlying etiology. The evolving understanding of the immune system has resulted in a more targeted approach to manage patients with different forms of uveitis, although clearly this approach is at a very early stage. Altered patterns of cellular processing and different cytokine expression, including TNF, IL-1, IL-2, IL-6, and IL17, have been defined in uveitis, and this has laid the pathway for targeted therapy. Furthermore, approved biologic therapies for some of the more common autoimmune illnesses have now been tested in uveitis. Adalimumab and infliximab have been the best studied anti-TNF agents and indeed have now been recommended by an expert panel as the first line of treatment for ocular manifestations of Behçet's disease and the second line of treatment for other forms of uveitis. Adalimumab has been recently approved for intermediate uveitis, posterior uveitis, and panuveitis. Other biologic agents have been tested, including daclizumab, a monoclonal antibody directed against IL-2, anti-IL1, and anti-IL-6 receptor agents and therapies that block antigen-presenting cell and T-cell interaction, such as abatacept. In small case series, other biologics such as interferon and rituximab have also been evaluated. Although these biologic therapies have provided a larger armamentarium to treat uveitis, challenges remain. Uveitis is not a disease, but a manifestation of many potential systemic diseases that may have specific individual therapeutic targets. Identification and characterization of these underlying diseases are not always possible and, more importantly, the most effective therapies for each entity have not been defined. In this study, an approach to manage patients with uveitis is presented and current therapy is reviewed.

Abstract
Therapy for autoimmune ophthalmic disease is currently evolving. The improved understanding of the abnormal immune response in the various forms of uveitis has resulted in targeted therapy. The aberrations of the immune system have been characterized by atypical cell populations, cytokine expression, and cell-cell interactions. Different patterns of cytokine expression have now been delineated in the abnormal uveal tract with exaggerated and/or abnormal expression of TNF, IL-1, IL-2, IL-6, and IL-17. The development of therapies for other conditions in which these cytokines play an important role has resulted in the availability of biological agents that have been adopted for use in the therapy for uveitis. Adalimumab and infliximab have been the best studied anti-TNF agents and indeed have now been recommended by an expert panel as first-line treatment of ocular manifestations of Behçet's disease and second-line treatment for other forms of uveitis (Levy-Clarke et al. (Ophthalmology, 2013). Other anti-TNF agents have been studied as well. Daclizumab, a monoclonal antibody directed against the IL-2 receptor, has also demonstrated utility in treating uveitis as have some of the anti-IL1 agents. Gevokizumab has been granted orphan drug designation for the treatment of resistant forms of uveitis. Therapies affecting IL-6, including tocilizumab are being studied, and available medications that block antigen presenting cell and T cell interaction such as abatacept have been reported to be effective in uveitis. Interferons as well as rituximab have also been evaluated in small studies. Although these biologic therapies have provided a larger armamentarium to treat uveitis, challenges remain. Uveitis is not a single illness; rather, it is a manifestation of many potential systemic diseases that may have very specific individual therapeutic targets. Identifying and characterizing these underlying diseases is not always achieved, and more importantly, the most effective therapies for each entity have not been defined.

Abstract
Uveitis is the third most common cause of blindness in developed countries. Considering the systemic and local complications of long-term corticosteroid therapy and the intolerance due to side effects and ineffectiveness of conventional chemotherapy, use of biologic response modifiers is a reasonable alternative in the treatment of non-infectious uveitis and persistent uveitic macular edema. The majority of the evidence presented here comes from open uncontrolled analyses. Based on these studies, tumor necrosis factor alpha inhibitors, especially infliximab and adalimumab, have been shown to be effective in the treatment of non-infectious uveitis in numerous studies. More research is necessary, particularly multi-center randomized clinical trials, to address the choice of biologic response modifier agent and the length of treatment as we employ biologic response modifiers in different types of uveitis and persistent uveitic macular edema.

Abstract
The cornea is normally devoid of blood and lymphatic vessels; however, a number of infectious/inflammatory diseases can induce corneal neovascularization (CNV). Tumor necrosis factor (TNF)-α, a well known pro-inflammatory cytokine, acts on the vascular endothelium by promoting vasodilatation, edema, and leukocyte recruitment, which are all commonly associated with the development of CNV. Corneal neovascularization is the second cause of blindness worldwide; hence, pharmacological TNF-α inhibition might represent an attractive therapeutic option. Although none of the existing TNF-α antagonists has been registered as a CNV inhibitor, three of them (etanercept, adalimumab, and infliximab) have been proposed to control ocular inflammation. More specifically, it has been demonstrated that infliximab is also effective in reducing hemangiogenesis and lymphangiogenesis in different animal models of CNV. In this article, we review the role of TNF-α on the ocular surface and, in particular, its specific role in the process of CNV. Moreover, we review existing literature and speculate on the potential role of TNF-α inhibitors in the treatment of CNV.

Abstract
Anterior uveitis (AU), inflammation of the iris, choroid or ciliary body, can cause significant eye morbidity, including visual loss. In the pediatric age group, the most common underlying diagnosis for AU is juvenile idiopathic associated uveitis and idiopathic AU, which are the focus of this paper. AU is often resistant to medications such as topical corticosteroids and methotrexate. In the past 15 years, biologic agents (biologics) have transformed treatment. In this review, we discuss those in widespread use and those with more theoretical applications for anterior uveitis. Tumor necrosis factor alpha inhibitors (anti-TNFα) have been available the longest and are used widely to treat pediatric uveitis. The effects of anti-TNFα in children are described mostly in small retrospective case series. Together, the literature suggests that the majority of children treated with anti-TNFα achieve decreased uveitis activity and reduced corticosteroid burden. However, many will have disease flares even on treatment. Only a few small studies directly compare outcomes between alternate anti-TNFα (infliximab and adalimumab). The use of different uveitis grading systems, inclusion criteria, and outcome measures makes cross-study comparisons difficult. Whether the achievement and maintenance of inactive disease occurs more frequently with certain anti-TNFα remains controversial. Newer biologics that modulate the immune system differently (e.g., interfere with Th17 activation through IL-17a and IL-6 blockade, limit T lymphocyte costimulation, and deplete B lymphocytes), have shown promise for uveitis. Studies of these agents are small and include mostly adults. Additional biologics are also being explored to treat uveitis. With their advent, we are hopeful that outcomes will ultimately be improved for children with AU. With many biologics available, much work remains to identify the optimal inflammatory pathway to target in AU.

Abstract
Since the first reported use in 2001 of an anti-tumor necrosis factor-alpha (TNF-α) agent, infliximab, for the treatment of uveitis, several new anti-TNF-α agents have emerged for the treatment of refractory noninfectious uveitides, although their use remains off-label in the US. These agents have demonstrated remarkable clinical antiinflammatory efficacy and a potential immunoregulatory role in selected uveitis patients, but it is currently unclear whether they can modify the natural history of disease. We review the rationale and clinical indications for this therapy, the differences between agents, how to manage dosing and intervals, and how to screen for and identify potential side effects. We also present a summary of the science behind the use of anti-TNF-α agents in ocular inflammation and the evidence for their efficacy.

Abstract
Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disorder that may cause joint destruction. Biological treatments targeting specific cytokines and cell interactions have transformed the outcomes of JIA. This review focuses on the selection of patients for and the timing and selection of biological treatment in JIA. Tumor necrosis factor (TNF) inhibitors remain the first choice for polyarticular JIA, followed by abatacept and tocilizumab. Monoclonal-antibody TNF inhibitors and abatacept are usually chosen for methotrexate-resistant uveitis. Recent clinical trials of canakinumab, rilonacept, and tocilizumab have obtained great improvement in both systemic and arthritic features in chronic systemic JIA patients. Current guidelines support the early use of a short-acting IL-1 antagonist for macrophage activation syndrome, a life-threatening complication. TREAT and ACUTE studies suggest that a therapeutic window of opportunity during early disease may exist in JIA. Early initiation of biological therapy may be associated with slower progression of joint damage and longer remission.

Abstract
Uveitis, a group of conditions characterized by intraocular inflammation, is a major cause of sight loss in the working population. Most uveitis seen in Western countries is noninfectious and appears to be autoimmune or autoinflammatory in nature, requiring treatment with immunosuppressive and/or anti-inflammatory drugs. In this educational review, we outline the ideal characteristics of drugs for uveitis and review the data to support the use of current and emerging therapies in this context. It is crucial that we continue to develop new therapies for use in uveitis that aim to suppress disease activity, prevent accumulation of damage, and preserve visual function for patients with the minimum possible side effects.

Abstract
Intraocular inflammatory eye disease is one of the important causes of ocular morbidity. Even though the prevalence of uveitis is less common in relation to diabetic retinopathy, glaucoma or age related macular degeneration, the complexity and heterogeneity of the disease makes it more unique. Putative uveitogenic retinal antigens incite innate immunity by the process of antigen mimicry and have been shown to be associated in patients with intraocular inflammatory disease by numerous experimental studies. Laboratory diagnostic tools to aid the etiologic association in intraocular inflammatory disease have evolved over the last two decades and we are entering into an era of molecular diagnostic tests. Sophisticated novel technologies such as multiplex bead assays to assess biological signatures have revolutionized the management of complex refractory uveitis. Nevertheless, there is still a long way to go to establish the causal relationship between these biomarkers and specific uveitic entities. Experimental studies have shown the supreme role of infliximab in the management of Behcet's disease. Despite significant experimental and case control studies, the deficiency of randomized clinical trials using these biologic agents has handicapped us in exploring them as a front line therapy in severe refractory uveitis. Studies still need to answer the safety of these potentially life threatening drugs in a selected group of patients and determine when to commence and for how long the treatment has to be given. This review article covers some basic concepts of cytokines in uveitis and their potential application for therapy in refractory uveitis.

Abstract
Juvenile idiopathic arthritis-related uveitis is the most common type of uveitis in childhood and one of the main causes of visual impairment in children. The introduction of biological treatment has widened the range of therapeutic options for children with uveitis refractory to standard nonbiologic immunosuppressants. Data from clinical trials suggest that both adalimumab and infliximab have demonstrated effectiveness and safety in open-label studies, although no large, randomized, controlled trials have been reported so far. The role of etanercept in treating juvenile idiopathic arthritis-related uveitis is not yet well defined. In our experience, anti-tumor necrosis factor therapy has been shown to be more effective than steroids and/or methotrexate in treating uveitis. Up to now, tumor necrosis factor blocking compounds have been reserved for the treatment of the most severe cases of refractory uveitis, and larger prospective clinical trials are required in order to better assess the safety of these new compounds.

Abstract
BACKGROUND Tumor necrosis factors (TNF) are a group of cytokines that play a role in systemic inflammation, stimulating the acute phase reaction. They are involved in systemic rheumatologic conditions such as rheumatoid arthritis and juvenile idiopathic arthritis, as well as ocular inflammatory conditions in the uveitis spectrum. Several drugs were developed to inhibit the action of TNF, thereby reducing inflammation. The three most commonly used TNF inhibitors in the US are etanercept, infliximab, and adalimumab. Newer drugs include certolizumab and golimumab. In this review, we discuss the differences in the mechanism of action, route of administration, indication, and efficacy of TNF inhibitors used in the treatment of ocular inflammation. METHODS A review of the literature in the PubMed, MEDLINE, and Cochrane databases was conducted to identify clinical trials, comparative studies, case series, and case reports describing the use of tumor necrosis factor inhibitors in uveitis therapy. The search was limited to primary reports published in English with human subjects from 1990 to the present, yielding 5,238 manuscripts. In addition, referenced articles from the initial searches were hand searched to identify additional relevant reports. After title and abstract selection, duplicate elimination, and manual search, 69 papers were selected for analysis. Exclusion criteria included review articles and case reports on the efficacy of etanercept, infliximab, and adalimumab. Manuscripts with fewer than 20 study subjects were excluded if other larger studies existed on the use of the same drug for a particular indication. Studies with <6 months of patient follow-up were also excluded, except in the case where no other data were available. Articles meeting these criteria were then reviewed by the three authors for inclusion in this review. RESULTS Tumor necrosis factor inhibitors have been shown to decrease inflammation associated with a number of rheumatologic conditions. Three of the five commercially available TNF inhibitors-etanercept, infliximab, and adalimumab-have been studied for their efficacy in treatment of ocular inflammation. Etanercept appears to be inadequate in controlling ocular inflammation and is not recommended for the treatment of uveitis. Infliximab and adalimumab, however, have shown encouraging results in multiple trials. Serious potential side effects such as infection, including reactivation of latent tuberculosis, malignancy, and demyelinating disease, may limit the use of TNF inhibitors in uveitis. Proper screening of patients prior to initiating these therapies may decrease these risks. DISCUSSION Early success with infliximab and adalimumab has paved the way for new TNF inhibitors and other corticosteroid-sparing drugs to emerge in the treatment of ocular inflammation. Future studies are on the horizon to determine the long-term safety and efficacy of newer TNF inhibitors such as certolizumab and golimumab.

Abstract
Uveitis is one of the leading causes of blindness worldwide. Noninfectious uveitis may be associated with other systemic conditions, such as human leukocyte antigen B27-related spondyloarthropathies, inflammatory bowel disease, juvenile idiopathic arthritis, Behçet’s disease, and sarcoidosis. Conventional therapy with corticosteroids and immunosuppressive agents (such as methotrexate, azathioprine, mycophenolate mofetil, and cyclosporine) may not be sufficient to control ocular inflammation or prevent non-ophthalmic complications in refractory patients. Off-label use of biologic response modifiers has been studied as primary and secondary therapeutic agents. They are very useful when conventional immunosuppressive therapy has failed or has been poorly tolerated, or to treat concomitant ophthalmic and systemic inflammation that might benefit from these medications. Biologic therapy, primarily infliximab, and adalimumab, have been shown to be rapidly effective for the treatment of various subtypes of refractory uveitis and retinal vasculitis, especially Behçet’s disease-related eye conditions and the uveitis associated with juvenile idiopathic arthritis. Other agents such as golimumab, abatacept, canakinumab, gevokizumab, tocilizumab, and alemtuzumab may have great future promise for the treatment of uveitis. It has been shown that with proper monitoring, biologic therapy can significantly improve quality of life in patients with uveitis, particularly those with concurrent systemic symptoms. However, given high cost as well as the limited long-term safety data, we do not routinely recommend biologics as first-line therapy for noninfectious uveitis in most patients. These agents should be used with caution by experienced clinicians. The present work aims to provide a broad and updated review of the current and in-development systemic biologic agents for the treatment of noninfectious uveitis.

Abstract
Monoclonal antibodies (mAbs) are antibodies of a single antigen specificity produced by identical immune cells, i.e., clones of a common germ cell. They offer unprecedented opportunities to drug development because of their ability to target almost any cell surface or secreted molecule with remarkable efficacy and safety. In this chapter, the application of human mAbs in the treatment of inflammatory diseases is reviewed. We discuss in detail several mAb-based drugs such as anti-tumor necrosis factor (anti-TNF), anti-interleukin-1 (anti-IL-1) receptor, anti-IL-6 receptor, anti-α4 integrin subunit, and anti-CD20 agents, all of which have been documented by clinical trials to be efficacious and have been approved for the therapy of several inflammatory and immune diseases, including rheumatoid arthritis, Crohn's disease, ulcerative colitis, spondyloarthropathies, juvenile arthritis, psoriasis, psoriatic arthritis, and others. These novel drugs can be used either as a monotherapy or in combination with other conventional therapeutic modalities, particularly if the disease under treatment is refractory to therapy using solely conventional techniques. As a large variety of mAb-based agents targeting a plethora of cytokines, chemokines, adhesion and co-stimulatory molecules, receptors, as well as diverse cell types, are presently under investigation, the therapeutic armamentarium of the clinician is expected to greatly broaden in the near future, providing improved patient care for a wide range of devastating diseases of our times.

Abstract
Inflammatory eye diseases are an important manifestation of many pediatric rheumatologic conditions. Early screening and diagnosis are imperative as these illnesses can not only result in significant visual morbidity but are also an indicator of systemic inflammation. Time to presentation of ocular inflammation varies significantly and can range from many years prior to the onset of systemic symptoms to well after the diagnosis of the rheumatologic disorder. Due to this variability in presentation, careful monitoring by an ophthalmologist is vital to preventing ocular complications and preserving vision. Both local and systemic immunosuppressive medications have been effective in the management of ocular disease. In this review, we will focus on the known ophthalmologic manifestations of common pediatric rheumatologic diseases and discuss recent advances in therapeutic considerations for these conditions.

Abstract
UNLABELLED We report our results with systemic Etanercept in patients with juvenile idiopathic arthritis in a joint ophthalmology-rheumatology clinic at a tertiary hospital. METHODS Patients with JIA on Etanercept were identified from a dedicated uveitis database. A retrospective review of electronic and paper-based patient records was performed. RESULTS Nine patients with JIA and current or previous treatment with Etanercept were identified, including six females and three males. Five patients with previous or current uveitis were noted. A further four were under observation for uveitis and required Etanercept for their joint disease. All nine patients had previously been taking Methotrexate, which had a suboptimal response in controlling arthritis or uveitis. Six out of nine patients did not show any uveitis activity at their last follow-up. Eyes of three patients still show signs of active inflammation in the anterior chamber (two on Etanercept and one off Etanercept). Severely impaired visual acuity (PL) was recorded in both eyes of one patient with long-standing persistent uveitis. Moderate visual loss in one eye of one patient was seen. The remaining seven patients did not show any significant loss of vision. Intraocular inflammation was not induced in any patient started on Etanercept. CONCLUSION Etanercept may be useful in controlling JIA-related uveitis or arthritis in a pediatric patient when Methotrexate has had a suboptimal response in controlling the inflammatory activity.

Abstract
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.

Abstract
OBJECTIVE To compare the effect of subconjunctivally injected bevacizumab, etanercept and the combination of both drugs on experimental corneal neovascularization in rats. DESIGN Experimental study. PARTICIPANTS 28 male Wistar-Albino rats. METHODS Right corneas of rats were cauterized by silver nitrate sticks. Rats were divided randomly and equally into 4 groups so that each group contained 7 subjects. Immediately after the cauterization, 0.05 ml normal saline was injected subconjunctivally in group 1 (control group); 0.05 ml (1.25 mg) bevacizumab was injected subconjunctivally in group 2; 0.05 ml (1.25 mg) etanercept was injected subconjunctivally in group 3; 0.05 ml (1.25 mg) bevacizumab and 0.05 ml (1.25 mg) etanercept was injected subconjunctivally in group 4. The rats were euthanized on the 8th day, and digital photographs were obtained before the eyes were enucleated. The area of corneal neovascularization was calculated from digital photographs. Corneal sections were analyzed by histopathologically. RESULTS The burn stimulus score was +1 or higher in all eyes. The difference of the neovascularization score between groups was found to be statistically significant (p = 0.001). The area of corneal neovascularization was 79.8% in group 1, 43.2% in group 2, 54.5% in group 3, and 34.8% in group 4. In group 4, corneal neovascularization was inhibited more than in the other groups. Histologic examination showed that the treatment groups had less neovascularization, inflammation, and fibroblast activity than the control group (p< 0.05). CONCLUSIONS Our study has shown that etanercept does have some antiangiogenic and anti-inflammatory effects in treatment of corneal neovascularization. The combination of bevacizumab and etanercept may be a promising approach in the treatment of corneal neovascularization.

Abstract
OBJECTIVE To evaluate the outcome of tumor necrosis factor-α inhibition (anti-TNF) for pediatric uveitis. METHODS We retrospectively assessed children (age ≤ 18 yrs) with noninfectious uveitis receiving anti-TNF at 5 uveitis centers and 1 pediatric rheumatology center. Incident treatment success was defined as minimal or no uveitis activity at ≥ 2 consecutive ophthalmological examinations ≥ 28 days apart while taking no oral and ≤ 2 eyedrops/day of corticosteroids. Eligible children had active uveitis and/or were taking higher corticosteroid doses. RESULTS Among 56 eligible children followed over 33.73 person-years, 52% had juvenile idiopathic arthritis (JIA) and 75% had anterior uveitis (AU). The Kaplan-Meier estimated proportion achieving treatment success within 12 months was 75% (95% CI 62%-87%). Complete absence of inflammatory signs with discontinuation of all corticosteroids was observed in an estimated 64% by 12 months (95% CI 51%-76%). Diagnoses of JIA or AU were associated with greater likelihood of success, as was the oligoarticular subtype among JIA cases. In a multivariable model, compared to those with JIA-associated AU, those with neither or with JIA or AU alone had a 75%-80% lower rate of achieving quiescence under anti-TNF, independent of the number of immunomodulators previously or concomitantly prescribed. Uveitis reactivated within 12 months of achieving quiescence in 14% of those continuing anti-TNF (95% CI 6%-31%). The incidence of discontinuation for adverse effects was 8%/year (95% CI 1%-43%). CONCLUSION Treatment with anti-TNF was successful and sustained in a majority of children with noninfectious uveitis, and treatment-limiting toxicity was infrequent. JIA-associated AU may be especially responsive to anti-TNF.

Abstract
Noninfectious uveitis is a potentially sight-threatening ocular disorder and variable therapeutic strategies have been proposed. Biologic therapies were introduced as a new option for patients with uveitis refractory to the conventional therapy using corticosteroids and immunosuppressive agents, and 10 years have passed since the initiation. In this review, the author summarizes current articles on the assessment of therapeutic application of biologics for refractory uveitis including other autoimmune diseases. Although some results are based on investigation with insufficient clinical trials, especially in biologics, the majority of biologics indicate preferable outcomes on refractory uveitis, with remarkable promise to increase the possibility of long-term remissions.

Abstract
INTRODUCTION Uveitis is an intriguing group of disorders characterized by inflammation of the uveal tract. Due to the potential grave consequences of the disease process, it is important to assess the various therapeutic options available for treating uveitis, and their outcomes. AREAS COVERED This review discusses the use of conventional agents in the management of uveitis, including discussion of the molecular and clinical properties of corticosteroids, antimetabolites, calcineurin inhibitors and alkylating agents and their side effects. In addition, it also discusses the molecular and clinical properties of novel biologic agents and their side effects. Moreover, recommendations as to when biologic agents should be employed are also discussed. EXPERT OPINION We recommend that in general (except in selected cases of Adamantiades-Behçet's disease) biologics should not be used as a first-line therapy for uveitis due to inconvenience, high cost, and potential immunosuppressive effects. However, many biologics are potent in inducing drug-free remission of uveitis and may be employed to manage recurrent diseases or diseases not responsive to conventional agents.

Abstract
Background. Infliximab (INF) has been shown to be beneficial in treating refractory uveitis, however, no data exist on optimal dosing and the efficacy of higher dosing. Objectives. To compare the efficacy of low-dose (LD) (<10 mg/kg), moderate-dose (MD) (≥10–15 mg/kg), and high-dose (HD) INF (≥15–20 mg/kg) in the treatment of uveitis. Methods. Retrospective chart review children with uveitis diagnosed at Childrens Hospital Los Angeles and Millers Children's Hospital, CA, USA. Results. Of the 34 INF-treated children, 6 patients received LD, 19 received MD, and 9 received HD. Average disease duration prior to therapy was 10.6, 24.6, and 37.1 months each group, respectively. Topical steroids were discontinued after an average of 3 months, 9.5 months, and 10.2 months in the LD, MD, and HD groups, respectively. We found that 66% of patients receiving LD, 42% of MD, and 66% receiving HD INF failed therapy and required either dose escalation or alternate medication for disease control. Conclusions. INF is beneficial in the treatment of uveitis, and dose escalation up to 4 times above the approved dose is often necessary to achieve disease control in patients with uveitis. Doses < 10 mg/kg every 4 weeks may not be sufficient to control disease.

Abstract
OBJECTIVES To develop and/or update fact sheets about TNFα antagonists treatments, in order to assist physicians in the management of patients with inflammatory joint disease. METHODS 1. selection by a committee of rheumatology experts of the main topics of interest for which fact sheets were desirable; 2. identification and review of publications relevant to each topic; 3. development and/or update of fact sheets based on three levels of evidence: evidence-based medicine, official recommendations, and expert opinion. The experts were rheumatologists and invited specialists in other fields, and they had extensive experience with the management of chronic inflammatory diseases, such as rheumatoid. They were members of the CRI (Club Rhumatismes et Inflammation), a section of the Société Francaise de Rhumatologie. Each fact sheet was revised by several experts and the overall process was coordinated by three experts. RESULTS Several topics of major interest were selected: contraindications of TNFα antagonists treatments, the management of adverse effects and concomitant diseases that may develop during these therapies, and the management of everyday situations such as pregnancy, surgery, and immunizations. After a review of the literature and discussions among experts, a consensus was developed about the content of the fact sheets presented here. These fact sheets focus on several points: 1. in RA and SpA, initiation and monitoring of TNFα antagonists treatments, management of patients with specific past histories, and specific clinical situations such as pregnancy; 2. diseases other than RA, such as juvenile idiopathic arthritis; 3. models of letters for informing the rheumatologist and general practitioner; 4. and patient information. CONCLUSION These TNFα antagonists treatments fact sheets built on evidence-based medicine and expert opinion will serve as a practical tool for assisting physicians who manage patients on these therapies. They will be available continuously at www.cri-net.com and updated at appropriate intervals.

Abstract
Pediatric uveitis differs from uveitis seen in adulthood not only because of the uveitis presentation and severity of disease but also by a worse prognosis and age-specific problems that may occur under therapy. Biologics are selective acting proteins that are manufactured by biotechnology. The greatest amount of knowledge to date exists for the TNF alpha blocking agents. Experimental and clinical studies showed that TNF alpha plays a significant role in the process of intraocular inflammation, so it was a logical step to use TNF blocking agents in uveitis therapy. Randomized controlled studies are rare, but pooled data (as presented here) of case series published show good evidence for the efficacy especially of infliximab and adalimumab. It is to be hoped that blindness and severe sight disabilities can be further reduced by this treatment in the future. From pediatric rheumatology we have learned about even newer biologics. With this review we want to show the weaknesses and strengths of therapy with biologics and want to help in choosing this treatment at the indicated time point in the disease.

Abstract
Tumor Necrosis Factor alpha (TNF-α) is a pleiotropic cytokine which plays a primary role in the induction of inflammation in autoimmune diseases. The newest anti-TNF-α agent is adalimumab (Humira, Abbott Pharmaceutical Inc.), a human-derived antibody. This review summarizes the characteristics of adalimumab, highlighting its clinical use in systemic and ocular inflammatory disorders, and the possible therapeutic strategies. Adalimumab has been successfully used for the treatment of rheumatoid arthritis, ankylosing spondylitis, and psoriasis arthritis. More recently, adalimumab has shown promising qualities in controlling intraocular inflammations, even though this has been used prevalently as a rescue therapy for unresponsive cases. This biologic agent was also used in pediatric cases, showing a good safety and efficacy profile. Albeit no direct comparison with other biologics has been done, and adalimumab seems to be equivalent to the other anti-TNF-α, the switching to adalimumab can offer a better uveitic control. Adalimumab is a promising drug for the treatment of uveitis, even though further studies are needed on its application as a primary therapy in uveitis.
