Efficacy of anti-tumour necrosis factor-α monoclonal antibodies in patients with non-infectious anterior uveitis.

OBJECTIVES: To assess the efficacy of monoclonal anti-tumour necrosis factor (TNF)-α agents in patients with anterior uveitis (AU) in terms of decrease of recurrences, variation of visual acuity and steroid sparing effect and to identify any demographic, clinical or therapeutic variables associated with a sustained response to monoclonal TNF-α inhibitors. METHODS: Data from patients suffering from AU treated with adalimumab, infliximab, golimumab or certolizumab pegol were retrospectively collected and statistically analysed. RESULTS: Sixty-nine patients (22 males, 47 females), corresponding to 101 eyes, were enrolled. The mean follow-up period was 29.25±23.51 months. The rate of ocular flares decreased from 42.03 events/100 patients/year recorded during the 12 months preceding the start of TNF-α inhibitors to 2.9 flares/100 patients/year after the start of treatment (p<0.0001). The overall decrease in ocular flares was 93.1%. No statistically significant changes were identified in the best corrected visual acuity during the follow-up period (p>0.99). The number of patients treated with corticosteroids at baseline was significantly higher compared with that referred to the 12-month evaluation (p<0.001) and to the last follow-up visit (p=0.006). Concomitant treatment with conventional disease-modifying anti-rheumatic drugs (cDMARDs) represented the sole clinical, demographic or therapeutic variable associated with long-term treatment duration (p=0.045, R2=0.87). CONCLUSIONS: Monoclonal TNF-α inhibitors induce a remarkable decrease in the recurrence of AU during a long-term follow-up period and lead to a significant steroid sparing effect along with stabilisation of visual acuity. Concomitant treatment with cDMARDs represented the sole variable associated with treatment duration in the long-term.

Serum immunoglobulin D levels in patients with Behçet's disease according to different clinical manifestations.

OBJECTIVES: Behçet's disease (BD) is an autoinflammatory disorders mainly characterised by recurrent oral aphthosis, genital ulcers, and uveitis. The involvement of immunoglobulin D (IgD) in BD physiopathology is still unclear. The aim of our study was to assess the role of IgD in BD by comparing circulating levels of IgD in a cohort of BD patients and healthy controls (HC), as well as by correlating IgD levels with BD activity and different clinical presentations. METHODS: Serum IgD and SAA levels were analysed by ELISA assay in ninety-nine serum samples collected from 72 BD patients and in 29 HC subjects. RESULTS: Serum concentration of IgD were higher in BD patients compared with HC (p=0.029), in patients with high serum amyloid A (SAA) levels compared with patients with normal SAA levels (p=0.035), and among subjects with active mucocutaneous involvement compared with other patients (p=0.036). No correlations were identified between IgD serum levels and disease activity assessed by the BD current activity form (BDCAF) (p=0.640). No differences were observed in the IgD serum levels between patients with and without specific disease manifestations. Increased SAA levels (Odds Ratio = 3.978, CI: 1.356 -11.676) and active mucocutaneous BD manifestations (Odds Ratio = 4.286, CI: 1.192 - 15.407) were associated with a high risk for increased IgD serum levels. CONCLUSIONS: Serum IgD levels are significantly increased in BD patients, especially among patients with active mucocutaneous manifestations, suggesting a possible role of IgD in BD pathogenesis and in the onset of mucosal and skin lesions.

Epidemiological profile of non-infectious uveitis from the rheumatologist's perspective: a survey from two tertiary referral centres in Italy.

OBJECTIVES: To describe the epidemiology of non-infectious uveitis (NIU) in two tertiary referral rheumatology units in Central and Southern Italy. METHODS: Two hundred and seventy-eight consecutive NIU patients (417 eyes) evaluated between January 2016 and January 2017 were enrolled. Collected data were analysed in accordance with the primary anatomic site of inflammation, clinical course, and laterality. RESULTS: The mean age at NIU onset was 36.92±18.30 years with a female-to-male ratio of 1.34:1. Anterior uveitis (AU) was identified in 151 (54.32%), posterior uveitis (PU) in 67 (24.10%), intermediate uveitis (IU) in 5.40% and panuveitis (PanU) in 16.19% patients. Bilateral involvement was identified in 50% of our cohort. Uveitis was acute in 33.81% of patients, while 24.46% and 41.73% had a chronic and recurrent course, respectively. Gender and laterality did not influence the anatomical pattern, while disease course was significantly more acute or chronic in AU (p<0.05) and chronic in IU (p<0.05). An associated systemic disease was identified in 116 patients (41.73%). Twenty-seven patients (9.7%) had a specific isolated eye disease, 135 patients (48.56%) had idiopathic NIU. Uveitis associated with a systemic disease was significantly bilateral (p=0.01) and acute or chronic (p<0.0001), while the isolated form showed an association with chronic course (p<0.0001) and unilaterality (p=0.01). CONCLUSIONS: The most common anatomic pattern of NIU has been AU, followed by PU, PanU and IU. A systemic disease (mainly Behçet's disease, ankylosing spondylitis and juvenile idiopathic arthritis) has been recognised in a fair proportion of the entire cohort. The rheumatologist should remain a central professional figure in the multidisciplinary team dealing with intraocular inflammation on a daily basis.

Biological therapies for the treatment of Behçet's disease-related uveitis beyond TNF-alpha blockade: a narrative review.

Intraocular inflammation is one of the more relevant complications of Behçet's disease (BD), which tends to respond poorly to different medications. The ocular histopathologic changes are basically identical to those occurring in other organs and consist in a necrotizing leukocytoclastic obliterative vasculitis, which is probably immune complex-mediated and affects both arteries and veins of all sizes. There are growing evidences showing the potential role of biologic agents other than anti-tumor necrosis factor (TNF)-α agents in the management of ocular-BD, which have been collected in this review, including interleukin-1 and interleukin-6 blockade, secukinumab, ustekinumab, daclizumab, rituximab, and alemtuzumab. Further large studies are needed to fully elucidate and establish the clinical efficacy of these different tools in the refractory ocular manifestations of BD.

Correlation of Serum Amyloid-A Levels, Clinical Manifestations, Treatment, and Disease Activity in Patients with Behçet's Disease.

BACKGROUND: Behçet's disease (BD) is an inflammatory disorder potentially leading to life- and sight-threatening complications. No laboratory marker correlating with disease activity or predicting the occurrence of disease manifestations is currently available. OBJECTIVES: To determine an association between serum amyloid-A (SAA) levels and disease activity via the BD Current Activity Form (BDCAF), to evaluate disease activity in relation to different SAA thresholds, to examine the association between single organ involvement and the overall major organ involvement with different SAA thresholds, and to assess the influence of biologic therapy on SAA levels. METHODS: We collected 95 serum samples from 64 BD patients. Related demographic, clinical, and therapeutic data were retrospectively gathered. RESULTS: No association was identified between SAA levels and BD disease activity (Spearman's rho = 0.085, P = 0.411). A significant difference was found in the mean BDCAF score between patients presenting with SAA levels < 200 mg/L and those with SAA levels > 200 mg/L (P = 0.027). SAA levels > 200 mg/L were associated with major organ involvement (P = 0.008). A significant association was found between SAA levels > 150 mg/dl and ocular (P = 0.008), skin (P = 0.002), and mucosal (P = 0.012) manifestations. Patients undergoing biologic therapies displayed more frequently SAA levels < 200 mg/L vs. patients who were not undergoing biologic therapies (P = 0.012). CONCLUSIONS: Although SAA level does not represent a biomarker for disease activity, it might be a predictor of major organ involvement and ocular disease relapse at certain thresholds in patients with BD.

Update on the Medical Management of Gastrointestinal Behçet's Disease.

Behçet's disease (BD) is a multisystemic disorder of unknown etiology mainly defined by recurrent oral aphthosis, genital ulcers, and chronic relapsing bilateral uveitis, all of which represent the "stigmata" of disease. However, many other organs including the vascular, neurological, musculoskeletal, and gastrointestinal systems can be affected. The gastrointestinal involvement in Behçet's disease (GIBD), along with the neurological and vascular ones, represents the most feared clinical manifestation of BD and shares many symptoms with inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis. Consequently, the differential diagnosis is often a daunting task, albeit the presence of typical endoscopic and pathologic findings may be a valuable aid to the exact diagnosis. To date, there are no standardized medical treatments for GIBD; therefore therapy should be tailored to the single patient and based on the severity of the clinical features and their complications. This work provides a digest of all current experience and evidence about pharmacological agents suggested by the medical literature as having a potential role for managing the dreadful features of GIBD.

Intravitreal Dexamethasone Implant as an Adjunct Weapon for Severe and Refractory Uveitis in Behçet's Disease.

BACKGROUND: The evidence on the use of dexamethasone implants in the treatment of Behçet's disease (BD)-related uveitis is limited to a few cases. OBJECTIVES: To evaluate the efficacy of dexamethasone implants on ocular functional, morphological, and clinical parameters in BD patients with severe refractory uveitis. METHODS: Five eyes from five BD patients were enrolled. A single intravitreal dexamethasone injection was applied to each eye. Best corrected visual acuity (BCVA), central macular thickness (CMT) assessed with optical coherence tomography, retinal vasculitis assessed by fluorescein angiography, vitreous haze score (Nussenblatt scale), intraocular pressure (IOP), and lens status (LOCS III, Lens Opacities Classification System III) were recorded at baseline and at 1, 3, and 6 month follow-up visits. RESULTS: At baseline, all eyes showed marked macular edema and 4/5 had concomitant active retinal vasculitis. Mean BCVA was increased from baseline at each control visit with a mean improvement of 0.26 ± 0.18 lines at 6 months follow-up. Mean CMT decreased from baseline at each control visit with a mean improvement at 6 months follow-up of 198.80 ± 80.08 µm. At the end of the study, none of the eyes showed macular edema and the mean CMT was 276.80 ± 24.94 µm. Retinal vasculitis resolved in all eyes. One eye experienced an IOP spike during treatment that resolved spontaneously, and one eye developed a clinically significant lens opacity at 6 months follow-up. CONCLUSIONS: Treatment with a dexamethasone implant in BD-uveitis and inflammatory macular edema was safe and effective as an additional treatment combined with systemic immunomodulatory drugs.

Impact of Uveitis on Quality of Life: A Prospective Study from a Tertiary Referral Rheumatology-Ophthalmology Collaborative Uveitis Center in Italy.

BACKGROUND: Non-infectious uveitis (NIU) leads to severe visual impairment, potentially impacting on health-related quality of life (QoL). OBJECTIVES: To investigate the impact of NIU on QoL. METHODS: Eighty NIU patients and 23 healthy controls completed the 36-item Short-Form Health Survey (SF)-36. The SF-36 values were statistically analyzed to evaluate differences between patients and healthy controls and to identify correlations between SF-36 subscores and clinical/demographic data. RESULTS: NIU patients showed a decrease in the physical component summary score (P < 0.0001) compared to healthy controls, while no difference was highlighted in the mental component summary score (P = 0.97). NIU patients showed a decrease in physical functioning (P = 0.008), role-physical (P = 0.003), bodily pain (P = 0.0001), general health (P < 0.0001), and social functioning (P = 0.01). Physical functioning was lower in patients with acute anterior uveitis (AAU) than in those with panuveitis (P = 0.003). No differences were found between patients with bilateral or unilateral NIU, isolated NIU, or NIU associated with systemic diseases and with or without ocular activity. No correlations were identified between best-corrected visual acuity and SF-36 subscores. Physical functioning (P = 0.02), bodily pain (P = 0.004), and social functioning (P = 0.02) were reduced in males versus females. CONCLUSIONS: QoL is impaired in individuals with NIU, particularly in the physical domains, general health, and social functioning. AAU affects physical functioning more than panuveitis. NIU seems to affect per se QoL disregarding inflammatory activity, visual impairment, and presence of associated systemic diseases.

The purinergic P2×7 receptor is expressed on monocytes in Behçet's disease and is modulated by TNF-α.

The P2×7 receptor (P2×7r) is expressed in innate immune cells (e.g. monocyte/macrophages), playing a key role in IL-1ß release. Since innate immune activation and IL-1ß release seem to be implicated in Behçet's disease (BD), a systemic immune-inflammatory disorder of unknown origin, we hypothesized that P2×7r is involved in the pathogenesis of the disease. Monocytes were isolated from 18 BD patients and 17 healthy matched controls. In BD monocytes, an increased P2×7r expression and Ca(2+) permeability induced by the selective P2×7r agonist 2'-3'-O-(4-benzoylbenzoyl)ATP (BzATP) was observed. Moreover, IL-1ß release from LPS-primed monocytes stimulated with BzATP was markedly higher in BD patients than in controls. TNF-α-incubated monocytes from healthy subjects almost reproduced the findings observed in BD patients, as demonstrated by the increase in P2×7r expression and BzATP-induced Ca(2+) intake. Our results provide evidence that in BD monocytes both the expression and function of the P2×7r are increased compared with healthy controls, as the possible result, at least in part, of a positive modulating effect of TNF-α on the receptor. These data indicate P2×7r as a new potential therapeutic target for the control of BD, further supporting the rationale for the use of anti-TNF-α drugs in the treatment of the disease.

Inhibition of interleukin-1 by canakinumab as a successful mono-drug strategy for the treatment of refractory Behçet's disease: a case series.

Recommendations related to ocular, mucosal and cutaneous involvement of Behçet's disease (BD) are mainly evidence-based, but in cases of vascular, neurological and gastrointestinal involvement there are no guidelines to define the best treatment strategy. We report three adult patients with BD, who received an interleukin-1ß inhibitor by subcutaneous injections, canakinumab (at the dosage of 150 mg every 6 weeks), after failure shown by corticosteroids and different combinations of immunosuppressant agents. The prompt and sustained clinical efficacy demonstrated by canakinumab as a monotherapy supports the opportunity of using this specific anti-interleukin-1ß agent as a valid therapeutic option for resistant or refractory BD. Open trials and observational studies should be performed to test canakinumab efficacy on a larger number of patients. The most appropriate dosage and intervals between administrations should be decided according to the individual patient, severity or recurrence of clinical manifestations and major organ involvement.

Subcortical low-intensity and restricted diffusion after first seizure in a child.

Our purpose was to increase the knowledge about subcortical low-intensity images on long repetition time by describing brain magnetic resonance images of a young boy after his first spontaneous seizure. Evident in the epileptogenic area were transient images of reversible subcortical low intensity on long-repetition time, T2*-weighted, and b = 0 s/mm2 diffusion, isointense signal on b = 1000 s/mm2 diffusion, and restricted diffusion. Most likely, mechanism was axonal flow disruption with iron accumulation and free radicals production induced during seizure.

Cavernous malformation of the optic nerve mimicking optic neuritis.

A 30-year-old woman developed acute visual loss and optic disc elevation in the left eye after breastfeeding her second son. The initial diagnosis was optic neuritis. However, MRI showed a lesion in left intraorbital and intracanalicular optic nerve and several cerebral lesions with imaging features of cerebral cavernous malformations (CCMs). Genetic testing was positive for abnormalities known to predispose to CCMs in the patient and her father, who also showed MRI evidence of CCMs. During a 44-month follow-up period in which no intervention took place, the patient's vision in the affected eye fluctuated but eventually became extinguished. Serial MRIs did not always show lesion changes that explained the visual deterioration. In familial CCM, pregnancy might be a "second hit" to genetically predisposed tissue.

The Presence of Uveitis Is Associated with a Sustained Response to the Interleukin (IL)-1 Inhibitors Anakinra and Canakinumab in Behçet's Disease.

Purpose: To identify factors associated with sustained response to interleukin (IL)-1 inhibition among demographic, clinical and therapeutic data in patients with Behçet disease (BD).Methods: BD patients treated with anakinra or canakinumab were enrolled. Patients were divided into two groups according to the clinical response: group 1 included subjects showing a treatment duration of at least 52 weeks and no secondary inefficacy during the first follow-up year; the remaining patients were included in the group 2. Demographic, clinical and therapeutic data were analyzed to identify significant differences between groups.Results: Eighteen patients were included in group 1 and 18 patients in group 2. A better response to IL-1 inhibitors was significantly more common among patients with BD-related uveitis (p = 0.006) and patients with a longer disease duration (p = 0.03).Conclusion: IL-1 blockade is effective in BD, especially in the subset of patients presenting eye involvement and in those with long-lasting disease.

Rapid and Sustained Efficacy of Golimumab in the Treatment of Multirefractory Uveitis Associated with Behçet's Disease.

PURPOSE: To evaluate golimumab (GOL) efficacy in the management of Behçet's disease (BD)-related uveitis. METHODS: We retrospectively collected data from 5 patients (8 eyes) with at least two recent relapses of uveitis, treated with GOL at the standard dose of 50 mg every 4 weeks. RESULTS: A complete control of intraocular inflammation was observed in 7/8 eyes (87.5%) at 12-month follow-up. The number of relapses 12 months before and after GOL initiation was 11 and 1, respectively. At baseline, four eyes had active retinal vasculitis (RV). At 3-month follow-up evaluation RV resolved in all eyes. Mean Best Corrected Visual Acuity was 6.93 ± 4.34 at baseline and 7.32 ± 3.87 at 12-months follow-up. CONCLUSION: We confirm GOL efficacy in reducing intraocular inflammation in BD, both in term of reduction in the number of uveitis relapses and in achieving a prompt resolution of active RV.

Ten-Year Retention Rate of Infliximab in Patients with Behçet's Disease-Related Uveitis.

PURPOSE: To evaluate the 10-year drug retention rate of infliximab (IFX) in Behçet's disease (BD)-related uveitis, the effect of a concomitant use of disease modifying anti-rheumatic drugs (DMARDs) on drug survival and differences according to the lines of biologic treatment. METHODS: Cumulative survival rates were studied using the Kaplan-Meier plot, while the Log-rank (Mantel-Cox) test was used to compare survival curves. RESULTS: Forty patients (70 eyes) were eligible for analysis. The drug retention rates at 12-, 24-, 60- and 120-month follow-up were 89.03%, 86.16%, 75.66% and 47.11% respectively. No differences were identified according to the use of concomitant DMARDs (p = 0.20), while a statistically significant difference was observed in relation to the different lines of IFX treatment (p = 0.014). Visual acuity improved from baseline to the last follow-up visit (p = 0.047) and a corticosteroid-sparing effect was observed (p < 0.0001). CONCLUSIONS: IFX retention rate in BD-uveitis is excellent and is not affected by concomitant DMARDs.

Cumulative retention rate of adalimumab in patients with Behçet's disease-related uveitis: a four-year follow-up study.

BACKGROUND/AIMS: Adalimumab (ADA) has been shown to be an effective treatment for Behçet's disease (BD)-related uveitis. We aimed at evaluating the cumulative retention rate of ADA during a 48-month follow-up period in patients with BD-related uveitis, the impact of a concomitant use of disease modifying anti-rheumatic drugs (DMARDs) on ADA retention rate, and differences according to the various lines of biologic therapy (ie, first- vs second-line or more). Predictive factors of response to ADA were also investigated. METHODS: We enrolled patients diagnosed with BD-related uveitis and treated with ADA between January 2009 and December 2016. Cumulative survival rates were studied using the Kaplan-Meier plot, while the log-rank (Mantel-Cox) test was used to compare survival curves. Statistical analysis was performed to identify differences according to the response to ADA. RESULTS: 54 consecutive patients (82 eyes) were eligible for analysis. The drug retention rate at 12- and 48-month follow-up was 76.9% and 63.5%, respectively. No statistically significant differences were identified according to the use of concomitant DMARDs (p=0.27) and to the different lines of ADA treatment (p=0.37). No significant differences were found between patients continuing and discontinuing ADA in terms of age (p=0.24), age at BD onset (p=0.81), age at uveitis onset (p=0.56), overall BD duration (p=0.055), uveitis duration (p=0.46), human leucocyte antigen-B51 positivity (p=0.51), and gender (p=0.47). CONCLUSIONS: ADA retention rate in BD-related uveitis is excellent and is not affected by the concomitant use of DMARDs or by the different lines of biological therapy. Negative prognostic factors for BD uveitis do not impact ADA efficacy.

Efficacy of adalimumab and infliximab in recalcitrant retinal vasculitis inadequately responsive to other immunomodulatory therapies.

The primary aim of the study was to evaluate the efficacy of tumor necrosis factor (TNF)-α blockers adalimumab (ADA) and infliximab (IFX) in refractory sight-threatening retinal vasculitis (RV) during a 12-month follow-up period. Secondary aims were to evaluate (i) any impact of concomitant conventional disease-modifying anti-rheumatic drugs (cDMARDs) and different lines of biologic therapy; (ii) any difference in terms of efficacy between ADA and IFX; (iii) consequences of biotherapies on the best-corrected visual acuity (BCVA); (iv) corticosteroid-sparing effect; and (vi) ocular complications during anti-TNF-α treatment. Demographic, clinical, and therapeutic data were retrospectively collected from the medical records and statistically analyzed. Forty-eight patients (82 eyes) were recruited, 22 (45.8%) of which received IFX and 26 (54.2%) ADA. The percentages of patients achieving RV remission within 3 and 12 months were 54 and 86%, respectively. A significant decrease in RV detection was identified from baseline to 3-month (p < 0.0001) and 12-month (p < 0.0001) assessments and between 3-month and 12-month visits (p = 0.004). No differences were identified in terms of RV resolution between (i) patients undergoing monotherapy and those co-administered with cDMARDs at 3-month (p = 0.560) and 12-month (p = 0.611) follow-up; (ii) biologic-naïve patients and those already exposed to other biologics at 3-month (p = 0.497) and 12-month (p > 0.99) visits; and (iii) patients treated with ADA and those treated with IFX (p = 0.357). During the study period, a statistically significant corticosteroid-sparing effect was observed (p = 0.0002), while BCVA values did not significantly change (p = 0.950). Anti-TNF-α monoclonal antibodies have proved excellent results in patients with recalcitrant sight-threatening RV.

Predictors of sustained clinical response in patients with Behçet's disease-related uveitis treated with infliximab and adalimumab.

To identify clinical variables capable of predicting long-term treatment duration of TNF-α inhibition in patients with Behçet's disease (BD)-related uveitis. Demographic, clinical, and therapeutic data were retrospectively collected from BD patients treated with the tumor necrosis factor (TNF)-α blockers infliximab and adalimumab. Patients still continuing TNF-α inhibitors at 48-month follow-up visits were classified as long-term responders and were statistically compared to patients discontinuing treatment before the 48-month visit. Forty-five patients (75 eyes) were enrolled. Thirty-two patients continued anti-TNF-α treatment for more than 48 months; 13 patients discontinued the treatment after a mean time of 12.3 ± 10.44 months due to lack (61.5%) or loss (38.5%) of efficacy. Baseline value of BD current activity form was the only variable discriminating long- and short-term responsive patients (p = 0.048, OR = 0.656, C.I. 95% 0.433-0.996). Disease activity levels at the start of treatment predict duration of response to monoclonal TNF antagonists in ocular BD.

The emerging role of interleukin (IL)-1 in the pathogenesis and treatment of inflammatory and degenerative eye diseases.

Interleukin (IL)-1 plays a key role in the pathogenesis and thereafter in the search for specific treatments of different inflammatory and degenerative eye diseases. Indeed, an overactivity of IL-1 might be an initiating factor for many immunopathologic sceneries in the eye, as proven by the efficacy of the specific IL-1 blockade in different ocular diseases. For instance, the uveitis in monogenic autoinflammatory disorders, such as Blau syndrome and cryopyrin-associated periodic syndrome, or in complex polygenic autoinflammatory disorders, such as Behçet's disease, has been successfully treated with IL-1 blockers. Similarly, therapy with the IL-1 receptor antagonist anakinra has proven successful also in scleritis and episcleritis in the context of different rheumatic conditions. Moreover, interesting findings deriving from animal models of ocular disease have set a rational basis from a therapeutic viewpoint to manage patients also with dry eye disease and a broadening number of ocular inflammatory and degenerative conditions, which start from an imbalance between IL-1 and its receptor antagonist.

IL-6 blockade in the management of non-infectious uveitis.

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.
