Abstract
Chronic wounds pose a significant clinical challenge due to their complex pathophysiology and the burden of long-term management. Monoclonal antibodies (mAbs) are emerging as a novel therapeutic option in managing difficult wounds, although comprehensive data on their use in wound care are lacking. This study aimed to explore existing scientific knowledge of mAbs in treating chronic wounds based on a rationale of direct inhibition of the main molecules involved in the underlying inflammatory pathophysiology. We performed a literature review excluding primary inflammatory conditions with potential ulcerative outcomes (e.g., hidradenitis suppurativa). mAbs were effective in treating wounds from 16 different etiologies. The most commonly treated conditions were pyoderma gangrenosum (treated with 12 different mAbs), lipoid necrobiosis, and cutaneous vasculitis (each treated with 3 different mAbs). Fourteen mAbs were analyzed in total. Rituximab was effective in 43.75% of cases (7/16 diseases), followed by tocilizumab (25%, 4/16 diseases), and both etanercept and adalimumab (18.75%, 3/16 conditions each). mAbs offer therapeutic potential for chronic wounds unresponsive to standard treatments. However, due to the complex molecular nature of wound healing, no single target molecule can be identified. Therefore, the use of mAbs should be considered as a translational approach for limited cases of multi-resistant conditions.

Anti-TNF vs tocilizumab in refractory uveitic cystoid macular edema due to Behcet's disease. Multicenter study of 49 patients. Semin Arthritis Rheum 2023; 58:152153. [PMID: 36549244 DOI: 10.1016/j.semarthrit.2022.152153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 11/29/2022] [Accepted: 12/09/2022] [Indexed: 12/23/2022]
Abstract
OBJECTIVE To compare the efficacy of TNF inhibitors (adalimumab (ADA) and infliximab (IFX)) vs tocilizumab (TCZ) in patients with refractory cystoid macular edema (CME) due to Behçet's disease (BD). METHODS Multicenter study of patients with BD-associated CME refractory to conventional and/or biological immunosuppressive drugs. From a cohort of 177 patients treated with anti-TNF and 14 patients treated with TCZ, we selected those with CME at baseline. We analyzed the evolution of macular thickness (main outcome), best-corrected visual acuity (BCVA) and intraocular inflammation (Tyndall and vitritis) from baseline up to 4 years in the 3 groups mentioned. RESULTS 49 patients and 72 eyes with CME were included. ADA was used in 25 patients (40 eyes), IFX in 15 (21 eyes) and TCZ in 9 (11 eyes). No statistically significant baseline differences were observed between the 3 groups except for a lower basal BCVA in TCZ group and a higher basal degree of intraocular inflammation in ADA group. Most patients from all groups had received several conventional immunosuppressive drugs. In addition, most patients in the group of TCZ had also received anti-TNF agents. Biological therapy was used in monotherapy (n=8) or combined with conventional immunosuppressive drugs (n=41). Macular thickness progressively decreased in the 3 groups, with no signs of CME after 1 year of treatment. Similarly, BCVA improvement and inflammatory intraocular remission was achieved in all groups. CONCLUSION Refractory CME associated with BD uveitis can be effectively treated either with ADA, IFX or TCZ. Furthermore, TCZ is effective in patients resistant to anti-TNF therapy.

Abstract
Immune checkpoint inhibitors are reshaping the prognosis of many cancer and are progressively becoming the standard of care in the treatment of many tumour types. Immunotherapy is bringing new hope to patients, but also a whole new spectrum of toxicities for healthcare practitioners to manage. Oncologists and specialists involved in the pluridisciplinary management of patients with cancer are increasingly confronted with the therapeutic challenge of treating patients with severe and refractory immune-related adverse events. In this Personal View, we summarise the therapeutic strategies that have been used to manage such toxicities resulting from immune checkpoint inhibitor treatment. On the basis of current knowledge about their pathogenesis, we discuss the use of new biological and non-biological immunosuppressive drugs to treat severe and steroid refractory immune-related adverse events. Depending on the immune infiltrate type that is predominant, we propose a treatment algorithm for personalised management that goes beyond typical corticosteroid use. We propose a so-called shut-off strategy that aims at inhibiting key inflammatory components involved in the pathophysiological processes of immune-related adverse events, and limits potential adverse effects of drug immunosuppression on tumour response. This approach develops on current guidelines and challenges the step-by-step increase approach to drug immunosuppression.

Abstract
Evidence suggests that the neuro-inflammation mechanisms associated with interleukin-12 (IL-12) may be linked to Alzheimer's diseases and cognitive aging. In this study, we speculate that single nucleotide polymorphisms (SNPs) in IL-12-associated genes, such as IL12A, IL12B, IL12RB1, and IL12RB2 genes, could be associated with cognitive aging individually and/or via complicated interactions in the elder Taiwanese population. There were totally 3,730 Taiwanese individuals with age ≥60 years from the Taiwan Biobank. Mini-Mental State Examination (MMSE) was analyzed for all participants. We employed MMSE scores to assess cognitive functions. Our analysis revealed that the IL12A gene (including rs116910715, rs78902931, and rs78569420), the IL12B gene (including rs730691), and the IL12RB2 gene (including rs3790558, rs4655538, rs75699623, and rs1874396) were associated with cognitive aging. Among these SNPs, the association with the IL12RB2 rs3790558 SNP remained significant after performing Bonferroni correction (P = 6.87 × 10−4). Additionally, we found that interactions between the IL12A and IL12RB2 genes influenced cognitive aging (P = 0.022). Finally, we pinpointed the effects of interactions between IL12A, IL12B, and IL12RB2 with physical activity (P < 0.001, = 0.002, and < 0.001, respectively). Our study suggests that the IL-12-associated genes may contribute to susceptibility to cognitive aging independently as well as through gene-gene and gene-physical activity interactions.

Interleukin-6 inhibition in the management of non-infectious uveitis and beyond. J Ophthalmic Inflamm Infect 2019; 9:17.

Abstract
Background Uveitis consists of a spectrum of inflammatory disorders characterized by ocular inflammation. The underlying pathophysiology consists of a complex interplay of various inflammatory pathways. Interleukin 6 is an important mediator of inflammation in uveitis and constitutes focus of research toward development of newer biological therapies in the management of non-infectious uveitis. Main body Pan-blockade of the inflammatory pathways with steroids is generally the first step in the management of acute non-infectious uveitis. However, long-term therapy with steroids is associated with systemic and ocular side effects, thereby necessitating the need for development of steroid sparing agents. IL-6 is a cytokine produced by various immune cells, in response to molecular patterns and affects multiple inflammatory cells. In particular, IL-6 is involved in differentiation of CD-4 cells into Th-17 cells that have been shown to play a significant role in various immune-mediated diseases such as uveitis. This broad-spectrum immunomodulatory activity makes IL-6 an excellent target for immunomodulatory therapy. Tocilizumab was the first IL-6 inhibitor to demonstrate efficacy in humans. It inhibits IL-6 from binding to both membrane-bound and soluble receptor and can be administered via intravenous (IV) and subcutaneous (SC) routes. It has been FDA approved for treatment of rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA). Following the approval in systemic diseases, its efficacy was demonstrated in various uveitis studies including a phase 2 clinical trial (STOP-Uveitis). Overall, tocilizumab has shown a good safety profile with the risk of malignancy consistent with that expected in patients with rheumatoid arthritis. However, tocilizumab therapy has been shown to increase the risk for gastrointestinal perforation and dose-dependent neutropenia. Following the success of tocilizumab, several other agents targeting the IL-6 pathway are in the pipeline. These include sirukumab, siltuximab, olokizumab, clazakizumab, and EBI-031 which target IL-6; Sarilumab and ALX-0061 act on the IL-6 receptor. Conclusion Studies have shown that IL-6 inhibitors can be effective in the management of NIU. In addition, the levels of IL-6 are elevated in other ocular vascular diseases such as retinal vein occlusion and diabetic macular edema. The roles of IL-6 inhibition may be broadened in the future to include the management of retinal vascular diseases and non-uveitic macular edema.

Anti-IL6-Receptor Tocilizumab in Refractory and Noninfectious Uveitic Cystoid Macular Edema: Multicenter Study of 25 Patients. Am J Ophthalmol 2019; 200:85-94. [PMID: 30660771 DOI: 10.1016/j.ajo.2018.12.019] [Citation(s) in RCA: 55] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2018] [Revised: 12/28/2018] [Accepted: 12/29/2018] [Indexed: 12/31/2022]
Abstract
PURPOSE Cystoid macular edema (CME) is a leading cause of blindness. This study assessed the efficacy and safety of tocilizumab (TCZ) in refractory CME. DESIGN Retrospective case series. METHODS Patients with CME secondary to noninfectious uveitis who had inadequate response to corticosteroids and at least 1 conventional immunosuppressive drug, and in most cases to other biological agents, were studied. CME was defined as central retinal thickness greater than 300 μm. The primary outcome measure was macular thickness. Intraocular inflammation, best-corrected visual acuity (BCVA), and corticosteroid-sparing effect were also analyzed. RESULTS A total of 25 patients (mean ± standard deviation age 33.6 ± 18.9 years; 17 women) with CME were assessed. Underlying diseases associated with uveitis-related CME are juvenile idiopathic arthritis (n = 9), Behçet disease (n = 7), birdshot retinochoroidopathy (n = 4), idiopathic (n = 4), and sarcoidosis (n = 1). The ocular patterns were panuveitis (n = 9), anterior uveitis (n = 7), posterior uveitis (n = 5), and intermediate uveitis (n = 4). Most patients had CME in both eyes (n = 24). TCZ was used in monotherapy (n = 11) or combined with conventional immunosuppressive drugs. Regardless of the underlying disease, compared to baseline, a statistically significant improvement in macular thickness (415.7 ± 177.2 vs 259.1 ± 499.5 μm; P = .00009) and BCVA (0.39 ± 0.31 vs 0.54 ± 0.33; P = .0002) was obtained, allowing us to reduce the daily dose of prednisone (15.9 ± 13.6 mg/day vs 3.1 ± 2.3 mg/day; P = .002) after 12 months of therapy. Remission was achieved in 14 patients. Only minor side effects were observed after a mean follow-up of 12.7 ± 8.34 months. CONCLUSION Macular thickness is reduced following administration of TCZ in refractory uveitis-related CME.

Abstract
Interleukein-6 (IL-6), is produced locally from infectious or injured lesions and is delivered to the whole body via the blood stream, promptly activating the host defense system to perform diverse functions. However, excessive or sustained production of IL-6 is involved in various diseases. In diseases, the IL-6 inhibitory strategy begins with the development of the anti-IL-6 receptor antibody, tocilizumab (TCZ). This antibody has shown remarkable effects on Castleman disease, rheumatoid arthritis and juvenile idiopathic arthritis. In 2017, TCZ was proven to work effectively against giant cell arteritis, Takayasu arteritis and cytokine releasing syndrome, initiating a new era for the treatment of these diseases. In this study, the defensive functions of IL-6 and various pathological conditions are compared. Further, the diseases of which TCZ has been approved for treatment are summarized, the updated results of increasing off-label use of TCZ for various diseases are reviewed and the conditions for which IL-6 inhibition might have a beneficial role are discussed. Given the involvement of IL-6 in many pathologies, the diseases that can be improved by IL-6 inhibition will expand. However, the important role of IL-6 in host defense should always be kept in mind in clinical practice.

Abstract
BACKGROUND To report the 24-month efficacy and safety of the interleukin-6 receptor antagonist tocilizumab (TCZ) for refractory uveitis-related macular edema (ME). METHODS Data were obtained by standardized chart review. Patients with quiescent uveitis seen at a single tertiary referral center, for whom ME was the principal cause of reduced visual acuity. OUTCOME MEASURES Central foveal thickness measured by optical coherence tomography; degree of anterior and posterior chamber; inflammation (Standardization of Uveitis Nomenclature Working Group criteria); and visual acuity (Snellen and logarithm of the minimum angle of resolution) were recorded in all patients during TCZ therapy at months 1, 3, 6, 12, 18, and 24. RESULTS Sixteen eyes from 12 patients (10 women) were included. Mean age was 34.6 years. Mean duration of ME was 13.2 years. All patients achieved 24 months of follow-up and that is the census date for data collection. Before TCZ was commenced, ME was present, and all patients had been previously treated with immunosuppressive therapy and biologic agents. Uveitis diagnoses were juvenile idiopathic arthritis associated, uveitis (n = 6), birdshot chorioretinopathy (n = 2), idiopathic panuveitis (n = 2), sympathetic ophthalmia (n = 1), and ankylosing spondylitis (n = 1). Mean central foveal thickness (95%; confidence interval) was 516 ± 55 μm at baseline, improving to 274 ± 13 at Month 12 (P = 0.0004), and sustained at 274 ± 14 at Month 24 of follow-up (P = 0.00039). Mean logarithm of the minimum angle of resolution best-corrected visual acuity improved from 0.78 ± 0.18 (Snellen 20/120 ± 20/30) at baseline to 0.42 ± 0.17 (20/52 ± 20/30) at Month 12 (P = 0.0001) and 0.40 ± 0.17 (20/50 ± 20/30) at Month 24 of follow-up (P = 0.0002). Tocilizumab therapy was withdrawn in 5 patients with sustained remission at Month 12 but in all, ME relapsed between 1 and 3 months after TCZ discontinuation. Rechallenge of TCZ infusions led to recovery of uveitis control and ME resolution. Two adverse events were reported during two 4-month follow-ups: one Grade 1 neutropenia and one community-acquired pneumonia. CONCLUSION In this long-term study, TCZ was effective and had a comparable safety profile to published data for TCZ use in other indications, when used for the treatment of refractory uveitis-related ME.

Abstract
Tocilizumab (TCZ) is the first humanized anti-interleukin-6 (IL-6) receptor monoclonal antibody approved for the treatment of patients with rheumatoid arthritis (RA), Castleman's disease, polyarticular and systemic juvenile idiopathic arthritis, and, most recently, giant cell arteritis as well as for the treatment of chimeric antigen receptor T cell therapy-induced cytokine release syndrome. The global clinical development program for TCZ provides a wealth of clinical data on intravenous TCZ, and more recent studies in patients with RA have provided evidence characterizing the role of intravenous TCZ as monotherapy in early disease and led to the introduction of a subcutaneous formulation of TCZ. In addition, recently published open-label extension and observational studies continue to support the long-term efficacy and safety of TCZ in both clinical trial and real-world settings. Given the involvement of IL-6-mediated signaling in inflammatory disorders, TCZ is also being investigated in other immunological diseases. In particular, a phase 2 trial on the safety and efficacy of subcutaneous TCZ in adults with systemic sclerosis shows clinically relevant improvements in skin sclerosis and lung function in these patients. Another anti-IL-6 receptor agent, sarilumab, targeting the IL6 receptor alpha subunit, was recently approved for the treatment of patients with RA, although long-term data for this biologic are not yet published. In this article we review the placement of TCZ in current treatment guidelines; recent clinical trial data, including quality of life in patients with RA; recent updates to the TCZ safety profile; recent investigations of TCZ in other immunological diseases; and the clinical development of other novel IL-6-targeted agents.

Abstract
Objective To assess the efficacy of tocilizumab (TCZ) in refractory uveitis of Behçet's disease (BD). Methods Multicentre study of patients with BD-associated uveitis. Patients were refractory to conventional and biologic immunosuppressive drugs. The main outcome measures were intraocular inflammation, macular thickness, visual acuity and corticosteroid-sparing effects. Results We studied 11 patients (7 men) (20 affected eyes); median age 35 years. Uveitis was bilateral in nine patients. The patterns of ocular involvement were panuveitis (n = 8, with retinal vasculitis in 4), anterior uveitis (n = 2) and posterior uveitis (n = 1). Cystoid macular oedema was present in seven patients. The clinical course was recurrent (n = 7) or chronic (n = 4). Before TCZ, patients had received systemic corticosteroids, conventional immunosuppressants and the following biologic agents: adalimumab (n = 8), infliximab (n = 4), canakimumab (n = 1), golimumab (n = 3), etanercept (n = 1). TCZ was used as monotherapy or combined with conventional immunosuppressants at 8 mg/kg/i.v./4 weeks (n = 10) or 162 mg/s.c./week (n = 1). At TCZ onset the following extraocular manifestations were present: oral and/or genital ulcers (n = 7), arthritis (n = 4), folliculitis/pseudofolliculitis (n = 4), erythema nodosum (n = 2), livedo reticularis (n = 1) and neurological involvement (n = 2). TCZ yielded rapid and maintained improvement in all ocular parameters of the patients, with complete remission in eight of them. However, this was not the case for the extraocular manifestations, since TCZ was only effective in three of them. After a mean (s.d.) follow-up of 9.5 (8.05) months, TCZ was withdrawn in two cases, due to a severe infusion reaction and arthritis impairment, respectively. Conclusion TCZ could be a therapeutic option in patients with BD and refractory uveitis.

Abstract
PURPOSE To report the results of tocilizumab (TCZ) treatment in patients with Behçet uveitis (BU) who had failed conventional, interferon alpha, and anti-Tumor necrosis factor-alpha therapy. METHODS We reviewed the records of five patients with BU treated with monthly infusions of TCZ 8 mg/kg. Outcome measures were visual acuity, anterior chamber cells, laser flare meter (LFM) readings, vitreous haze, central macular thickness (CMT), and fluorescein angiography (FA) score. RESULTS The clinical inactivity of BU and 20/50 or better vision were achieved in three female and two male patients treated with TCZ for 5-19 months. The mean LFM reading was reduced from 15.4 ± 2.7 to 5.0 ± 0.9 ph/ms; the mean CMT from 324.7 ± 36.6 µm to 280.2 ± 34.1 µm; and the mean FA score from 20.6 ± 5.4 to 9.3 ± 4.5 µm at the last visit. The only side effect was a slight elevation of the total cholesterol level in one patient. CONCLUSIONS Tocilizumab may be a safe and effective therapeutic option for refractory BU.

Abstract
Interleukin-6 (IL-6) is a prototypical cytokine featuring functional pleiotropy and redundancy. Under situations of stress, such as infection or tissue injury, IL-6 is rapidly synthesized and plays a major role in host defense. However, uncontrolled excessive or persistent production of IL-6 has a pathological effect in various diseases. Thus, IL-6 blockade was expected to become a novel therapeutic strategy for IL-6–mediated inflammatory diseases, and the first-in-class IL-6 inhibitor tocilizumab, which blocks IL-6 activity by inhibiting IL-6 binding to its receptor, was developed. Clinical trials of tocilizumab have verified its efficacy and tolerable safety profile in several diseases, and it has been approved for the treatment of patients with rheumatoid arthritis, Castleman's disease, systemic and polyarticular juvenile idiopathic arthritis, and giant cell arteritis. Off-label use and clinical trials strongly indicate that tocilizumab will be applicable for a wide variety of acute and chronic inflammatory diseases.

Abstract
Interleukin-6 (IL-6) is a key cytokine that is strongly up-regulated during infection and inflammation. Featuring pleiotropic activity, IL-6 is responsible for the induction of hepatic acute-phase proteins, trafficking of acute and chronic inflammatory cells, differentiation of adaptive T cell responses, homeostatic regulation, and tissue regeneration. Dysregulated IL-6 production has been associated with the development of a wide variety of systemic immune-mediated, chronic diseases, and even certain types of cancer. From the ocular perspective, significant elevation of IL-6 has been found in ocular fluids derived from diabetic macular edema, retinal vein occlusion, and refractory/chronic uveitis patients. During the last decade, tocilizumab, a neutralizing monoclonal antibody (mAb) that targets the IL-6 receptor (IL-6R), has been approved for the treatment of rheumatoid arthritis in >100 countries worldwide. Furthermore, it has been reported to be effective for the treatment of a number of autoimmune diseases including uveitis and its associated macular edema. Currently numerous candidate molecular strategies targeting the IL-6 signaling pathways are in progress through clinical trials in various disorders. Herein we discuss the basic biology of IL-6 and its pathological role in the development of immune-mediated conditions, particularly focusing on inflammatory eye diseases. It also provides an overview of the on-going clinical trials with the new anti-IL-6 mAbs and their potential use in the clinical practice.

Abstract
ᅟ: Behçet's disease (BD) is a systemic vasculitis characterised by a relapsing remitting course, affecting multiple organ systems. In the eye, it is a cause of potentially blinding inflammation in the form of uveitis. Management of uveitis in BD often requires the use of systemic immunosuppression, in order to reduce disease activity and prevent accumulation of irreversible damage. Whilst corticosteroids remain the mainstay of treatment, long-term use is limited by the development of adrenocorticotrophic side effects. There has therefore been significant interest in the use of corticosteroid-sparing immunosuppressive agents, and more recently, biologic therapies. Recent publications have demonstrated biologic therapy to have beneficial effects both on overall disease control, and quality of life for patients with BD. Widespread use of such agents is however limited, partly by the lack of high quality research evidence, and partly by the prohibitive cost of biologic treatments. In this review, we discuss the most recent research investigating the use of biologic therapy in uveitis due to BD, with consideration of health economics and quality of life outcomes.

Abstract
Behçet disease is currently considered an "autoinflammatory disease" triggered by infection and environmental factors in genetically predisposed individuals. Although the disease is characterized by recurrent oral and genital aphthous ulcers and ocular involvement, it can affect multiple organ systems. Complex aphthosis is characterized by recurrent oral and/or genital aphthous ulcers. It is important to evaluate the patient with complex aphthosis for Behçet disease and related systemic disorders. We discuss the etiopathogenesis, clinical features, diagnostic criteria, and treatment approaches for complex aphthosis and Behçet disease in light of the current literature.

Abstract
Interleukin-6 (IL-6) is a multifunctional cytokine that affects a variety of cells in the body such as osteoclasts, hepatocytes, endothelial cells, epithelial cells, white and red blood cells and etc. Elevated levels of IL-6 have been detected in many ocular diseases. Studies show that IL-6 has a major role in the pathology of glaucoma, CRVO, macular edema, ocular neovascularization, posterior capsule opacity formation, keratitis, dry eye disease, allergic eye disease, ocular autoimmune disease, corneal chemical burn, ocular inflammation and so on. IL-6 does its effects through the classic or trans-signal pathways in cells. Blocking of IL-6 signal pathways via Tocilizumab or other chemicals and therapeutics will help to overcome complications related to ocular diseases.

Abstract
Several pathogenetic studies have paved the way for a newer more rational therapeutic approach to non-infectious uveitis, and treatment of different forms of immune-driven uveitis has drastically evolved in recent years after the advent of biotechnological drugs. Tumor necrosis factor-α targeted therapies, the first-line recommended biologics in uveitis, have certainly led to remarkable results in patients with non-infectious uveitis. Nevertheless, the decision-making process turns out to be extremely difficult in anti-tumor necrosis factor or multidrug-resistant cases. Interleukin (IL)-6 holds a critical role in the pathogenic pathways of uveitis, due to its extended and protean range of effects. On this background, manipulation of IL-6 inflammatory cascade has unraveled encouraging outcomes. For instance, rising evidence has been achieved regarding the successful use of tocilizumab, the humanized monoclonal antibody targeted against the IL-6 receptor, in treating uveitis related to juvenile idiopathic arthritis or Behçet's disease. Similar findings have also been reported for uveitis associated with systemic disorders, such as rheumatoid arthritis or multicentric Castleman disease, but also for idiopathic uveitis, the rare birdshot chorioretinopathy, and even in cases complicated by macular edema. This work provides a digest of all current experiences and evidences concerning IL-6 blockade, as suggested by the medical literature, proving its potential role in the management of non-infectious uveitis.

Abstract
Behçet's disease (BD) is a chronic relapsing and remitting vasculitis of unknown aetiology. It has the capacity to affect almost all organ systems because of its potential to involve both arteries and veins of all sizes, resulting in significant organ-threatening morbidity and mortality. Traditionally known as the 'silk road' disease, it has a worldwide occurrence. The aetiopathological mechanisms of disease development in BD remain poorly understood, but genome wide studies show human leukocyte antigen and non-human leukocyte antigen associations. Environmental influences and genetic factors may have a role in the aetiopathogenetic mechanisms that lead to development of the disease, indicating the autoimmune and auto-inflammatory nature of BD. The evidence base for treatment is limited but new knowledge is emerging and current treatment options range from symptomatic treatment, through to non-biological and biological immunosuppressive drugs, to cover the spectrum of clinical manifestations.

Abstract
A 33-year-old man with history of lymphoma was misdiagnosed as multiple sclerosis (MS) 18 months previously, developed intermediate uveitis, unresponsive to interferon, and corticosteroids. A diagnosis of Behçet's disease (BD) was made on the basis of recurrent orogenital ulceration, erythema nodosum, and a positive pathergy test. The patient was started on Tocilizumab and experienced an improvement in visual acuity and intraocular inflammation over the following 2 weeks. In patients with BD-related uveitis, Tocilizumab can be an effective alternative to anti-tumor necrosis factor alpha medications.

Abstract
As a pro-inflammatory cytokine, the 21-kDa glycoprotein interleukin-6 (IL-6) plays a crucial role in the initiation of acute inflammation, as well in the perpetuation of a chronic inflammatory immune response. Thus, IL-6 might be involved in the pathogenesis of various autoimmune diseases. So far, the IL-6-rezeptor-antibody tocilizumab (TCZ, RoActemtra®) is the only approved drug for the treatment of IL-6-mediated disease, including rheumatoid arthritis (RA), systemic juvenile idiopathic (sJIA) and polyarticular juvenile arthritis (pJiA), as well as Castleman's disease (in Japan only). In recent years, an emerging number of case reports and small uncontrolled case series have reported on the successful treatment of various other chronic inflammatory diseases, which has resulted in the idea of a broad therapeutic potential for IL-6 blockade. Numerous IL-6 targets are currently in phase II/III study programs for RA as well as for other indications. This review focuses on the development of tocilizumab and other IL-6 targets as a therapeutic option for various diseases in rheumatology.

Abstract
PURPOSE To evaluate tocilizumab (TCZ) efficacy in severe and refractory birdshot chorioretinopathy (BSCR). METHODS Assessment of BSCR patients refractory to conventional immunosuppressive and anti-TNF-α drugs who underwent TCZ therapy. RESULTS Two HLA-A29 positive patients (man/37 years and woman/38 years; four affected eyes) with BSCR were studied. They had a chronic bilateral posterior uveitis. Patient 1 had been treated with intraocular and oral corticosteroids, cyclosporine A, and infliximab whereas Patient 2 received intravenous methylprednisolone pulses, cyclosporine A, azathioprine, and adalimumab. At TCZ onset they had macular edema (four eyes); visual acuity (VA) impairment (four eyes); vitritis (one eye); and diffuse angiographic signs of vasculitis (periphlebitis) (two eyes). Improvement of VA and OCT was observed following TCZ therapy in both patients. After a follow-up of 18 months (Patient 1) and 10 months (Patient 2), respectively, a corticosteroid sparing effect without any adverse effects was achieved in both cases. CONCLUSIONS TCZ was effective in two patients with BSCR refractory to anti-TNF-α agents.

Abstract
OBJECTIVE To determine whether horses with clinically diagnosed Equine Recurrent Uveitis (ERU) and those with Leptospirosis infection have a specific cytokine profile in their aqueous humor (AH) and serum that differs from horses with uveitis secondary to other ocular inflammatory processes and from horses with normal eyes. ANIMALS STUDIED Twenty-five client-owned horses with uveitis that were presented to the North Carolina State University Ophthalmology Service, and four University-owned horses without history or clinical signs of ocular disease. PROCEDURE Samples of AH and serum were obtained from horses with ERU (n=13), acute or non-recurrent uveitis (UV; n=7), uveitis secondary to infectious keratitis (IK; n=5), and normal eyes (N; n=4). Cytokine levels in AH and serum were quantified using a multiplex bead immunoassay. Leptospiral antibody titers in serum and AH and PCR for Leptospiral DNA in AH were performed. RESULTS In the AH of horses with ERU, increased levels of IL-1a, IL-4, IL-6, IL-8, IL-12p70, FGF-2, G-CSF, and RANTES were measured compared to UV, IK and N eyes, but the differences were not significant. However, IL-10 was significantly higher in ERU eyes compared to IK and N (P=0.029; 0.013), and IP-10 in ERU eyes was significantly higher than in UV and N (P=0.004). Furthermore, MCP-1 was significantly higher in ERU than N (P=0.04). In the serum, increased levels of IL-1a, IL-4, IL-6, IL-8, IL-12p70, fractalkine, and G-CSF were measured in horses with ERU, but the levels were not significantly higher than those observed in UV, IK, or N horses. However, serum IP-10 levels in horses with ERU were significantly higher than in UV and N horses (P=0.005) and MCP-1 levels were significantly higher in ERU than N (P=0.03). Horses with marked ocular inflammation had significantly higher serum levels of G-CSF, IL-1a, fractalkine, IL-13, IL-4, IL-17a, IL-12p70, IFN-γ, and MCP-1. Elevated IL-10 in AH was significantly associated with disease chronicity, both overall and in ERU eyes (P=0.049), and in horses with positive ocular leptospiral titers or leptospiral PCR, significant elevations of IL-10 (P=0.0018; 0.0032) and IP-10 (P=0.0342; 0.043) were detected in the AH compared to leptospiral negative eyes. CONCLUSIONS The anti-inflammatory cytokine IL-10 and the pro-inflammatory cytokine IP-10 appear to play an important role in ERU. Further studies are needed to further clarify and characterize cytokine profiles of specific ocular inflammatory diseases, but multiplex bead immunoassay technology shows promise as a diagnostically valuable tool.

Abstract
Eye-derived fluids, including tears, aqueous humour and vitreous humour often contain molecular signatures of ocular disease states. These signatures can be composed of cytokines, chemokines, growth factors, proteases and soluble receptors. However, the small quantities (<10 µl) of these fluids severely limit the detection of these proteins by traditional enzyme-linked immunosorbent assay or Western blot. To maximise the amount of information generated from the analysis of these specimens, many researchers have employed multiplex immunoassay technologies for profiling the expression or modification of multiple proteins from minute sample volumes.

Abstract
INTRODUCTION Behçet's syndrome (BS) is a systemic inflammatory disorder characterized by a wide range of potential clinical manifestations with no gold-standard therapy. However, the recent classification of BS at a crossroads between autoimmune and autoinflammatory syndromes has paved the way to new further therapeutic opportunities in addition to anti-tumor necrosis factor agents. AREAS COVERED This review provides a digest of all current experience and evidence about pharmacological agents recently described as having a role in the treatment of BS, including interleukin (IL)-1 inhibitors, tocilizumab, rituximab, alemtuzumab, ustekinumab, interferon-alpha-2a, and apremilast. EXPERT OPINION IL-1 inhibitors currently represent the most studied agents among the latest treatment options for BS, proving to be effective, safe and with an acceptable retention on treatment. However, since BS is a peculiar disorder with clinical features responding to certain treatments that in turn can worsen other manifestations, identifying new treatment options for patients unresponsive to the current drug armamentarium is of great relevance. A number of agents have been studied in the last decade showing changing fortunes in some cases and promising results in others. The latter will potentially provide their contribution for better clinical management of BS, improving patients' quality of life and long-term outcome.

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
BACKGROUND Drug discovery has undergone major transformations in the last century, progressing from the recognition and refinement of natural products with therapeutic benefit, to the systematic screening of molecular libraries on whole organisms or cell lines and more recently to a more target-based approach driven by greater knowledge of the physiological and pathological pathways involved. Despite this evolution increasing challenges within the drug discovery industry are causing escalating rates of failure of development pipelines. DISCUSSION We review the challenges facing the drug discovery industry, and discuss what attempts are being made to increase the productivity of drug development, including a refocusing on the study of the basic biology of the disease, and an embracing of the concept of 'translational research'. We consider what ophthalmic drug discovery can learn from the sector in general and discuss strategies to overcome the present limitations. This includes advances in the understanding of the pathogenesis of disease; improvements in animal models of human disease; improvements in ophthalmic drug delivery and attempts at patient stratification within clinical trials. As we look to the future, we argue that investment in ophthalmic drug development must continue to cover the whole translational spectrum (from 'bench to bedside and back again') with recognition that both biological discovery and clinical understanding will drive drug discovery, providing safe and effective therapies for ocular disease.

Abstract
INTRODUCTION In Behcet's disease (BD), interleukin (IL)-6 drive the immune-mediated inflammatory process. The IL-6 receptor can be targeted using tocilizumab. As an off-label treatment, we tested its efficacy in patients with BD. METHODS Overall, 4 patients with refractory BD were treated with tocilizumab, 8mg/kg/4 weeks. Patients were clinically and biologically assessed before administering each dose and the literature was reviewed. RESULTS Tocilizumab was found to be safe and well tolerated. BD activity decreased significantly in all patients, and prednisone dose was reduced in all cases (up to 50% of the baseline dose). Treatment appeared effective in alleviating skin/mucosal effects, neurological involvement, and uveitis, but less effective for arthralgia and abdominal pain. A very short time lag between the onset of treatment with tocilizumab and the clinical response was observed. The literature review revealed 11 previous cases reporting improvement to BD with this treatment, and 3 previous cases without efficacy. CONCLUSIONS We reported the most important study treating refractory BD with tocilizumab; this treatment could be safe and efficient, but will require further evaluation by randomized clinical trials.

Abstract
Uveitis is an inflammatory process that initially starts in the uvea, but can also affect other adjacent eye structures, and is currently the fourth cause of blindness in developed countries. Corticoids are probably the most widespread treatment, but resorting to other immunosuppressive treatments is a frequent practice. Since the implication of different cytokines in uveitis has been well demonstrated, the majority of recent treatments for this disease include inhibitors or antibodies against these. Nevertheless, adequate treatment for each uveitis type entails a difficult therapeutic decision as no clear recommendations are found in the literature, despite the few protocolized clinical assays and many case-control studies done. This review aims to present, in order, the mechanisms and main indications of the most modern immunosuppressive drugs against cytokines.

Abstract
INTRODUCTION Treatment of adult, noninfectious uveitis remains a major challenge for ophthalmologists around the world, especially in regard to recalcitrant cases. It is reported to comprise approximately 10% of preventable blindness in the USA. The cause of uveitis can be idiopathic or associated with infectious and systemic disorders. The era of biologic medical therapies provides new options for patients with otherwise treatment-resistant inflammatory eye disease. AREAS COVERED This two-part review gives a comprehensive overview of the existing medical treatment options for patients with adult, noninfectious uveitis, as well as important advances for the treatment ocular inflammation. Part I covers classic immunomodulation and latest information on corticosteroid therapy. In part II, emerging therapies are discussed, including biologic response modifiers, experimental treatments and ongoing clinical studies for uveitis. EXPERT OPINION The hazard of chronic corticosteroid use in the treatment of adult, noninfectious uveitis is well documented. Corticosteroid-sparing therapies, which offer a very favorable risk-benefit profile when administered properly, should be substituted. Although nothing is currently approved for on-label use in this indication, many therapies, through either translation or novel basic science research, have the potential to fill the currently exposed gaps.

Abstract
Behçet disease is a chronic inflammatory systemic disorder, characterized by a relapsing and remitting course. It manifests with oral and genital ulcerations, skin lesions, uveitis, and vascular, central nervous system and gastrointestinal involvement. The main histopathological finding is a widespread vasculitis of the arteries and veins of any size. The cause of this disease is presumed to be multifactorial involving infectious triggers, genetic predisposition, and dysregulation of the immune system. As the clinical expression of Behçet disease is heterogeneous, pharmacological therapy is variable and depends largely on the severity of the disease and organ involvement. Treatment of Behçet disease continues to be based largely on anecdotal case reports, case series, and a few randomized clinical trials.

Abstract
Interleukin-6 (IL-6) is a key cytokine featuring redundancy and pleiotropic activity. It plays a central role in host defence against environmental stress such as infection and injury. Dysregulated, persistent interleukin (IL)-6 production has been implicated in the development of various autoimmune, chronic inflammatory diseases and even cancers. Significant elevation of IL-6 has been found in ocular fluids derived from refractory/chronic uveitis patients. In experimental autoimmune uveitis models with IL-6 knock-out mice, IL-6 has shown to be essential for inducing inflammation. IL-6 blockade can suppress acute T helper type 17 (Th17) responses via its differentiation and, importantly, can ameliorate chronic inflammation. Tocilizumab, a recombinant humanized anti-IL-6 receptor antibody, has been shown to be effective in several autoimmune diseases, including uveitis. Herein, we discuss the basic biology of IL-6 and its role in development of autoimmune conditions, focusing particularly on non-infectious uveitis. It also provides an overview of efficacy and safety of tocilizumab therapy for ocular inflammatory diseases.

Abstract
Vascular inflammation contributes to the defence against invading microbes and to the repair of injured tissues. In most cases it resolves before becoming apparent. Vasculitis comprises heterogeneous clinical entities that are characterized by the persistence of vascular inflammation after it has served its homeostatic function. Most underlying mechanisms have so far remained elusive. Intravascular immunity refers to the surveillance of the vasculature by leucocytes that sense microbial or sterile threats to vessel integrity and initiate protective responses that entail most events that determine the clinical manifestations of vasculitis, such as end-organ ischaemia, neutrophil extracellular traps generation and thrombosis, leucocyte extravasation and degranulation. Understanding how the resolution of vascular inflammation goes awry in patients with systemic vasculitis will facilitate the identification of novel pharmacological targets and bring us a step closer in each patient to the selection of more effective and less toxic treatments.

Paradoxical mucocutaneous flare in a case of Behçet's disease treated with tocilizumab. Clin Rheumatol 2014; 34:1141-3.

Abstract
We report on a patient with a long-standing history of recurrent oral aphthosis and pseudofolliculitis, diagnosed with Behçet's disease (BD), previously treated with high-dose prednisone, colchicine, cyclosporine, cyclophosphamide and methotrexate, all of which were partially effective. Treatment with the chimeric mouse-human anti-tumour necrosis factor (TNF)-α monoclonal antibody infliximab brought about the resolution of mucocutaneous lesions for a period of 6 years. After an oral and articular BD relapse, the anti-interleukin-6 agent tocilizumab was started in association with high-dose prednisone. Unexpectedly, the patient experienced a paradoxical mucocutaneous flare following tocilizumab administration, which worsened after the second infusion. Tocilizumab was then discontinued, and total recovery was achieved after the patient was started on the fully human anti-TNF-α monoclonal antibody golimumab in association with colchicine and methylprednisolone.

Abstract
Behçet syndrome is a systemic inflammatory disorder characterized by multiorgan involvement such as oral and genital ulcers, uveitis, skin lesions as well as by less frequent, but often more severe, central nervous system and vascular manifestations. The pathogenetic mechanisms are still incompletely known; however the interaction between a specific genetic background and environmental or infectious factors certainly contributes to the immune dysregulation that characterizes this disease. The discovery of new immunological pathways in Behçet syndrome pathogenesis may help us to set up new treatments. In this review, we will focus our attention on the possible mechanisms underlying Behçet syndrome pathogenesis and their potential role as novel therapeutic targets.

Abstract
OBJECTIVES To investigate the influences of various factors on the relapse of acute neurological attacks in patients with Behçet's disease (BD). METHODS Sixty-one patients, who met the international classification criteria for BD, had attacks of acute neuro-Behçet's disease (NBD) and could be followed up at least for 2 months, including 60 patients in our multicenter retrospective survey on BD patients in 2011. The factors associated with relapse of acute neurological attacks were assessed. RESULTS Twenty-one of 61 patients had been taking cyclosporine A (CyA) at the onset of acute NBD. All the 21 patients with CyA and 33 of the 40 patients without CyA had eye involvement. There were no significant differences in demographic features, clinical symptoms, MRI findings, the need for, and responses to corticosteroid therapy including pulse therapy between patients with CyA and those without CyA. CyA was withdrawn in 19 of 21 patients with CyA. Of note, patients with CyA showed significantly lower relapse rates than those without CyA (HR 0.1283, 95% CI: 0.0788-0.7836, p = 0.0186 as calculated by log-rank test). Moreover, colchicine was found to reduce the relapse rates in patients with acute NBD without CyA (HR 0.2771, 95% CI: 0.0827-0.9422, p = 0.0450 [log-rank test]). CONCLUSION These results indicate that CyA-related acute neurological manifestations are almost identical with CyA-unrelated acute events of NBD, except for the paucity of relapse on withdrawal of CyA. The data also demonstrate that colchicine is effective to prevent relapses of acute neurological attacks especially in patients with CyA-unrelated acute NBD.
