Few data are available regarding the optimal treatment of multiple sclerosis (MS)-related uveitis. The aim of this study was to describe clinical features of MS-associated uveitis and determine how MS treatment affects the course of uveitis. Retrospective, multicenter study. Patients were divided into two groups according to the use (group 2) or not (group 1) of immunomodulatory drugs. Characteristics of uveitis and treatment were reviewed. A total of 68 eyes from 36 patients (17 in group 1 and 19 in group 2) were included. All patients were treated with topical and/or systemic steroids for uveitis. Uveitis occurred 1-17 years prior to neurologic symptoms in 78% of patients. Uveitis was more severe in group 2 (puveitis (p = 0.06). MS-related uveitis has often a favorable evolution. Patients on interferon-beta have more severe and chronic uveitis. As far as we are concerned, interferon-beta given on the sole indication of uveitis is not recommended. If steroid-sparing agent is required for intraocular inflammation, immunosuppressive drugs should be considered.

The clinical case of tattoo-associated uveitis was first described by Lubeck and Epstein in 1952. Uveitis is accompanied by induration and hyperemia of tattoo skin, which can precede, follow or manifest simultaneously with uveitis. The diagnosis is determined on clinical grounds after exclusion of other causes. Uveitis is usually bilateral, chronic and vision impairment is variable. Tattoo-associated uveitis should be remembered in differential diagnosis due to the growing interest in tattoo.Key words: uveitis, tattoo, masquerade syndrome.

Pediatric uveitis differs from adult-onset uveitis and is a topic of special interest because of its diagnostic and therapeutic challenges. Children with uveitis are often asymptomatic and the uveitis is often chronic, persistent, recurrent, and resistant to conventional treatment. Anterior uveitis is the most common type of uveitis in children; the prevalence of intermediate, posterior, and panuveitis varies geographically and among ethnic groups. Regarding etiology, most cases of pediatric uveitis are idiopathic but can be due to systemic inflammatory disorders, infections, or a manifestation of masquerade syndrome. Ocular complications include cataracts, hypotony or glaucoma, band keratopathy, synechiae formation, macular edema, optic disc edema, choroidal neovascular membranes, and retinal detachment. These complications are often severe, leading to irreversible structural damage and significant visual disability due to delayed presentation and diagnosis, persistent chronic inflammation from suboptimal treatment, topical and systemic corticosteroid dependence, and delayed initiation of systemic disease‒modifying agents. Treatment for noninfectious uveitis is a stepwise approach starting with corticosteroids. Immunomodulatory therapy should be initiated in cases where quiescence cannot be achieved without steroid dependence. Patients should be monitored regularly for complications of uveitis along with systemic and ocular adverse effects from treatments. The goals are to achieve steroid-free durable remission, to reduce the risk of sight-threatening complications from the uncontrolled ocular inflammation, and to avoid the impact of lifelong burden of visual loss on the child and their family. Multidisciplinary management will ensure holistic care of affected children and improve the support for their families. Copyright 2018 Asia-Pacific Academy of Ophthalmology.

Uveitis and Gender: The Course of Uveitis in Pregnancy

Full Text Available The hormonal and immunological changes in pregnancy have a key role in maintaining maternal tolerance of the semiallogeneic foetus. These pregnancy-associated changes may also influence the course of maternal autoimmune diseases. Noninfectious uveitis tends to improve during pregnancy. Specifically, uveitis activity tends to ameliorate from the second trimester onwards, with the third trimester being associated with the lowest disease activity. The mechanism behind this phenomenon is likely to be multifactorial and complex. Possible mechanisms include Th1/Th2 immunomodulation, regulatory T-cell phenotype plasticity, and immunosuppressive cytokines. This clearly has management implications for patients with chronic sight threatening disease requiring systemic treatment, as most medications are not recommended during pregnancy due to lack of safety data or proven teratogenicity. Given that uveitis activity is expected to decrease in pregnancy, systemic immunosuppressants could be tapered during pregnancy in these patients, with flare-ups being managed with local corticosteroids till delivery. In the postpartum period, as uveitis activity is expected to rebound, patients should be reviewed closely and systemic medications recommenced, depending on uveitis activity and the patient’s breastfeeding status. This review highlights the current understanding of the course of uveitis in pregnancy and its management to help guide clinicians in managing their uveitis patients during this special time in life.

To describe the main characteristics of a cohort of patients with uveitis referred to a multidisciplinary unit in northern Spain. Retrospective analysis of clinical records of patients evaluated in the Multidisciplinary Unit of the Navarra Hospital Complex from the period January 2010 until March 2015. An analysis was performed on the demographic characteristics, origin, types of uveitis, laterality, and aetiology. The present series was also compared with 2 previous series from Castilla y León and Barcelona. A total of 500 patients were identified, with a mean age of 47.9±16.4 years, with 50% women. The most frequent type of uveitis was anterior uveitis (65.4%), followed by posterior uveitis (17.6%), panuveitis (15.2%), and intermediate uveitis (1.8%). The origin was unclassifiable in 31.2%, followed by non-infectious systemic disease in 29.2%. Ankylosing spondylitis was the most frequent cause in 10.8% of patients, followed by herpes infection in 9.2%, and toxoplasmosis in 7.8%, respectively. Compared with the 2other cohorts, the present cohort showed a higher proportion of unilateral anterior uveitis. Furthermore, the patients from the Navarra series had a higher prevalence of unilateral and idiopathic uveitis compared to the series from Barcelona. The main characteristics of the present cohort of patients with uveitis are similar to those of patients from other regions of our country. Unilateral anterior uveitis and idiopathic uveitis were the most frequent in our series. Copyright © 2016 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U.

Doycheva, D; Deuter, C; Zierhut, M

2014-12-01

Intermediate uveitis is a form of intraocular inflammation in which the vitreous body is the major site of inflammation. Intermediate uveitis is primarily treated medicinally and systemic corticosteroids are the mainstay of therapy. When recurrence of uveitis or side effects occur during corticosteroid therapy an immunosuppressive treatment is required. Cyclosporine A is the only immunosuppressive agent that is approved for therapy of uveitis in Germany; however, other immunosuppressive drugs have also been shown to be effective and well-tolerated in patients with intermediate uveitis. In severe therapy-refractory cases when conventional immunosuppressive therapy has failed, biologics can be used. In patients with unilateral uveitis or when the systemic therapy is contraindicated because of side effects, an intravitreal steroid treatment can be carried out. In certain cases a vitrectomy may be used.

Presentation of suspected pediatric uveitis: Pediatric uveitis is usually managed in specialized ophthalmic centers in the UK. Meaningful data acquisition in these clinics may be helpful in clinical governance, and healthcare planning in a specialty that is gradually changing due to changes in treatment choices. Retrospective analysis of prospectively acquired data in the Liverpool pediatric uveitis database was performed. Analysis of our data, based on 147 patients, with a mean age of 10 years, indicated a female to male ratio of 2:1. 99% of patients were Caucasian. Our data indicates 86% of all patients attending the uveitis clinic were diagnosed with juvenile idiopathic arthritis, followed by intermediate uveitis 5% and idiopathic uveitis 4%. 46% of patients required treatment. Systemic treatment included methotrexate (34%), prednisolone (14%), etanercept (6%), ciclosporin (6%), mycophenolate (3%), and infliximab (1%). Severe visual loss (defined by counting fingers or below vision) was seen in 10 eyes despite appropriately treated chronic uveitis. Our data shows uveitis-related ocular morbidity in a predominantly pediatric Caucasian population. Patients with severe and chronic uveitis may experience significant uveitis-related complications and subsequent visual loss despite aggressive treatment.

To evaluate the frequency, high-risk factors, and visual prognosis of rhegmatogenous retinal detachment (RRD) in patients with uveitis. Retrospective case-control study. We included 1387 consecutive patients with uveitis who consulted our uveitis clinic from January 1990 through December 1997 of whom 43 patients (46 eyes) with RRD were identified. The retinal detachment (RD) controls were 212 consecutive patients with RRD (221 eyes, first occurrence of RD, not associated with uveitis) who were admitted for surgery in the period from April 1999 to April 2000. The uveitis control group consisted of 150 age-matched patients (210 eyes) selected from the entire uveitis series. Retrospective analysis of clinical data. The presence of RRD and eventual risk factors for RRD, such as myopia, retinal lattice degeneration, prior intraocular surgery, anatomic location of uveitis, its specific diagnosis, and clinical manifestations. Furthermore, the surgical and nonsurgical outcomes of RRD, as well as the results of various treatment regimens, were analyzed. RRD was identified in 3.1% of the patients with uveitis. RRD was most frequently associated with panuveitis (6.6%). RRD was associated more frequently with infectious (7.6%) than noninfectious uveitis (2.1%). At the onset of RRD, uveitis was active in most (46%) affected eyes. Proliferative vitreoretinopathy was present in 30% of the uveitic RRD eyes at presentation in contrast to 12% of the RRD control eyes. In uveitic RRD, the retina was reattached in 59% of eyes with a single operation; the final anatomic reattachment rate was 88%. Finally, a visual acuity of less than 20/200 was present in 71% of the uveitic RRD eyes, 10% of which had no light perception. We discovered a high prevalence of RRD in patients with active panuveitis and infectious uveitis and document that uveitis in itself is a risk factor for the development of RRD. The visual prognosis of RRD in uveitis was poor because of the uveitis itself and the

To analyse the role of interferon-β or glatiramer acetate in reducing the inflammatory episodes of intra-ocular inflammation in multiple sclerosis-associated uveitis. A study was conducted on a non-randomised, retrospective case series of 13 patients with proven multiple sclerosis and uveitis (minimum follow-up, 12 months). All patients were given immunomodulatory treatment (interferon-β or glatiramer acetate) to control the course of the multiple sclerosis. Patients were compared to themselves before initiating the treatment, in order to assess the difference in uveitis episodes. The main outcome measurements were the number of uveitis episodes with/without immunomodulatory treatment. Uveitis was bilateral in 10 (77%) out of 13 patients. Intermediate uveitis was observed in 11 patients, retinal vasculitis in 3 patients, and one patient was classified as a posterior uveitis. The patients had a mean of 4.15±3.1 episodes of uveitis (range 1-10) during the follow-up period (148.6±84.3 months). When compared to their pre-treatment status, patients on treatment with interferon-β or glatiramer acetate showed a significant decrease of 0.36 episodes of ocular inflammation per year (P=.02). Mild side effects related to immunomodulatory treatment were observed in 6 (46%) patients, 3 (23%) patients with a flu-like syndrome, and 3 (23%) patients with a skin rash. Interferon β or glatiramer acetate could be effective in reducing the uveitis episodes in patients with multiple sclerosis-associated uveitis, and was well tolerated in most patients.

In the Standardization of Uveitis Nomenclature (SUN working group′s international workshop for reporting clinical data the consensus reached was that the term IU should be used for that subset of uveitis where the vitreous is the major site of the inflammation and if there is an associated infection (for example, Lyme disease or systemic disease (for example, sarcoidosis. The diagnostic term pars planitis should be used only for that subset of IU where there is snow bank or snowball formation occurring in the absence of an associated infection or systemic disease (that is, "idiopathic". This article discusses the clinical features, etiology, pathogenesis, investigations and treatment of IU.

Uveitis is a term used to describe inflammation of the choroid, iris, or ciliary body, which make up the uveal tract. It can be idiopathic or associated with a systemic disease which may be infectious or noninfectious. With the exception of B-scan ultrasonography, current imaging methods for diagnosing and monitoring uveitis are predominately non-radiologic. Although MRI has been anecdotally shown to detect various inflammatory conditions of the globe, such as posterior scleritis, endophthalmitis, and posterior uveitis secondary to Vogt-Koyanagi-Harada disease, a more comprehensive review of the MRI findings in uveitis of various etiologies is presented here. The MRI and CT studies of seven patients with uveitis and the clinical history of three of them (not available in four patients) were reviewed. Etiologies included ankylosing spondylitis, relapsing polychondritis, Vogt-Koyanagi-Harada disease, sarcoidosis, and tuberculosis. Increased gadolinium enhancement of the uveal tract, which is visualized as the enhancing layer immediately deep to the low-signal sclera, was seen on all six MRI studies. Diffusion-weighted imaging of a case with posterior uveitis and subretinal effusions revealed restriction within the uvea and effusions. Two patients had inflammatory nodules adherent to the uvea, two patients had vitreous humor abnormalities, and one patient exhibited proximal perineural and perimuscular spread of enhancement. Uveoscleral thickening and enhancement with a posterior calcification were observed in the patient with chronic uveitis imaged with CT. Increased uveal tract enhancement is a common finding in patients with uveitis, regardless of anatomic distribution and etiology. MRI can also further evaluate complications of uveitis and help differentiate it from masquerade syndromes. (orig.)

Literature reports on ophthalmological manifestations related to tularemia, a zoonose caused by the bacterium Francisella tularensis, largely refer to Parinaud's oculoglandular syndrome, which consists of the association of conjunctivitis with preauricular lymphadenitis. In this paper, we report a case of intraocular inflammation during tularemia infection. A 52-year-old Caucasian man was diagnosed with unilateral uveitis. The uveitis was posterior, with a 2+ vitritis and a large yellowish lesion involving the macula with an overlying sub-retinal detachment, extending inferiorly, and subretinal hemorrhages. Fluorescein angiography showed a late hyperfluorescence with focal vascular leakage. Ultrasound biomicroscopy confirmed the presence of a 3.8 mm parietal granuloma with a few calcifications in the left eye. While extensive work-up eliminated any other infectious and non-infectious etiology, tularemia was diagnosed by advanced serology consisting of two-dimensional Western-immunoblotting. The patient, a hunter, recalled having killed rabbits in the days before the symptoms appeared. Uveitis was rapidly controlled following treatment with doxycycline, yet three years after initiation of the treatment, the patient still complained of loss of vision in the left eye with a central scotoma. Posterior uveitis may be an infrequent manifestation of tularemia infection, and therefore this infection should be considered in the differential diagnosis of intraocular inflammation in areas where F. tularensis is endemic.

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease of childhood, with JIA-associated uveitis its most common extra-articular manifestation. JIA-associated uveitis is a potentially sight-threatening condition and thus carries a considerable risk of morbidity. The aetiology of the condition is autoimmune in nature with the predominant involvement of CD4(+) T cells. However, the underlying pathogenic mechanisms remain unclear, particularly regarding interplay between genetic and environmental factors. JIA-associated uveitis comes in several forms, but the most common presentation is of the chronic anterior uveitis type. This condition is usually asymptomatic and thus screening for JIA-associated uveitis in at-risk patients is paramount. Early detection and treatment aims to stop inflammation and prevent the development of complications leading to visual loss, which can occur due to both active disease and burden of disease treatment. Visually disabling complications of JIA-associated uveitis include cataracts, glaucoma, band keratopathy and macular oedema. There is a growing body of evidence for the early introduction of systemic immunosuppressive therapies in order to reduce topical and systemic glucocorticoid use. This includes more traditional treatments, such as methotrexate, as well as newer biological therapies. This review highlights the epidemiology of JIA-associated uveitis, the underlying pathogenesis and how affected patients may present. The current guidelines and criteria for screening, diagnosis and monitoring are discussed along with approaches to management.

An international, expert-led consensus initiative to develop systematic, evidence-based recommendations for the treatment of noninfectious uveitis in the era of biologics. The availability of biologic agents for the treatment of human eye disease has altered practice patterns for the management of noninfectious uveitis. Current guidelines are insufficient to assure optimal use of noncorticosteroid systemic immunomodulatory agents. An international expert steering committee comprising 9 uveitis specialists (including both ophthalmologists and rheumatologists) identified clinical questions and, together with 6 bibliographic fellows trained in uveitis, conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol systematic review of the literature (English language studies from January 1996 through June 2016; Medline [OVID], the Central Cochrane library, EMBASE, CINAHL, SCOPUS, BIOSIS, and Web of Science). Publications included randomized controlled trials, prospective and retrospective studies with sufficient follow-up, case series with 15 cases or more, peer-reviewed articles, and hand-searched conference abstracts from key conferences. The proposed statements were circulated among 130 international uveitis experts for review. A total of 44 globally representative group members met in late 2016 to refine these guidelines using a modified Delphi technique and assigned Oxford levels of evidence. In total, 10 questions were addressed resulting in 21 evidence-based guidance statements covering the following topics: when to start noncorticosteroid immunomodulatory therapy, including both biologic and nonbiologic agents; what data to collect before treatment; when to modify or withdraw treatment; how to select agents based on individual efficacy and safety profiles; and evidence in specific uveitic conditions. Shared decision-making, communication among providers and safety monitoring also were addressed as part of the recommendations

To report a possible association between human papilloma virus (HPV) vaccination and uveitis. Spontaneous reports from the National Registry of Drug-Induced Ocular Side effects, World Health Organization and Food and Drug Administration were collected on uveitis associated with human papilloma virus vaccination. A MEDLINE search was performed using keywords "uveitis," "iritis," "iridocyclitis," "human papilloma virus," "Cervarix", and "Gardasil." Data garnered from spontaneous reports included the age, gender, adverse drug reaction (ADR), date of administration, concomitant administration of other vaccinations, time until onset of ADR, other systemic reactions, and dechallenge and rechallenge data. A total of 24 case reports of uveitis associated with human papilloma virus vaccination were identified, all cases were female, and the median age was 17. Median time from HPV vaccination to reported ADR was 30 days (range 0-476 days). According to World Health Organization criteria, the relationship between human papilloma virus vaccination and uveitis is "possible." Causality assessments are based on the time relationship of drug administration, uveitis development and re-challenge data. Clinicians should be aware of a possible bilateral uveitis and papillitis following HPV vaccination.

Purpose of review Pediatric uveitis is relatively uncommon, accounting for only 5–10% of all patients with uveitis. However, owing to high prevalence of complications and devastating outcomes, its lifetime burden can be significant. Recent findings Immunomodulatory therapy has been associated with better outcomes in noninfectious pediatric uveitis. However, effective treatments are limited by medication-related complications, including multiorgan toxicities and systemic side effects. Summary We review the current therapies available to treat pediatric uveitis, discuss novel and future therapies, and provide clinical recommendations utilizing these new agents. The consideration for treatment regimens in noninfectious pediatric uveitis is multifactorial. Understanding past, present, and future technology will aid in treatment of a complex and refractory disease. PMID:23872814

The treatment of noninfectious uveitis continues to remain a challenge for many ophthalmologists. Historically, clinical trials in uveitis have been sparse, and thus, most treatment decisions have largely been based on clinical experience and consensus guidelines. The current treatment paradigm favors initiation then tapering of corticosteroids with addition of steroid-sparing immunosuppressive agents for persistence or recurrence of disease. Unfortunately, in spite of a multitude of highly unfavorable systemic effects, corticosteroids are still regarded as the mainstay of treatment for many patients with chronic and refractory noninfectious uveitis. However, with the success of other conventional and biologic immunomodulatory agents in treating systemic inflammatory and autoimmune conditions, interest in targeted treatment strategies for uveitis has been renewed. Multiple clinical trials on steroid-sparing immunosuppressive agents, biologic agents, intraocular corticosteroid implants, and topical ophthalmic solutions have already been completed, and many more are ongoing. This review discusses the results and implications of these clinical trials investigating both alternative and novel treatment options for noninfectious uveitis. PMID:26035763

Uveitis is a frequent (20-50%) and early feature of sarcoidosis. Typical sarcoid uveitis presents with mutton-fat keratic precipitates, iris nodules, and anterior and posterior synechiae. Posterior involvement includes vitreitis, vasculitis, and choroidal lesions. Cystoid macular edema is the most important and sight-threatening consequence. Histologic proof from a biopsy is the gold standard for the diagnosis of ocular sarcoidosis. An international workshop has recently established diagnostic criteria for sarcoidosis uveitis when biopsy is unavailable or negative: these are based on a combination of ophthalmological findings and laboratory tests. The value of recent techniques, such as PET-scan and endoscopic ultrasound-guided, fine-needle aspiration of intrathoracic nodes needs to be assessed in future studies. Corticosteroids are the mainstay treatment for sarcoidosis. Systemic corticosteroids are indicated when uveitis does not respond to topical corticosteroids or when there is bilateral posterior involvement, especially macular edema and occlusive vasculitis. In up to 15% of cases, additional immunosuppression is used, including methotrexate, azathioprine, and mycophenolate mofetil. Infliximab and adalimumab have been recently proposed for the treatment of refractory or sight-threatening systemic sarcoidosis. Copyright © 2014 Elsevier B.V. All rights reserved.

The treatment of noninfectious uveitis includes steroids and immunomodulatory drugs, the use of which has increased in the last few years, and the options have been enriched with the development of new treatments. However, clear therapeutic guidelines and protocols have not been developed. The purpose is to analyze the response to the drugs used and the characteristics of the patients treated at a multidisciplinary uveitis clinic. Observational and retrospective study of the patients attended to from January 2012 to December 2015. Infectious, posttraumatic and postoperative uveitis, as well as masquerade syndrome, were excluded. Two hundred six patients were included. Overall, 58.80% had uveitis without association of systemic disease, mostly idiopathic uveitis, and 35.65% had uveitis with systemic involvement, mainly related to spondyloarthritis. Uveitis without systemic association and anterior uveitis achieved disease control with local treatment more frequently than others (p=.002 and p treatment. Among those treated with immunomodulators, 53.26% needed a second drug and 31.52% needed a third drug. Women required immunomodulators more often than men (P=.042). Methotrexate was the most widely used immunomodulator. Posterior uveitis responded less favorably to the second immunomodulator than anterior uveitis (p=.006). Almost half of the patients needed an immunomodulatory drug and some of them required successive drug changes. Intermediate uveitis was the most treatment-refractory uveitis.

Full Text Available Background/Aim. Epidemiological studies of blindness in a working age population require a precise definition of the true connection of uveitis and visual damage. Since most patients with more severe types of uveitis are hospitalized in tertiary referral uveitis service, our aim was to determine whether age, sex and age of onset of uveitis, as well as duration of visual loss and its causes influence the degree of visual damage in patients with different types of uveitis. Methods. The data were collected from medical records of 237 patients at the Department for Uveitis of the Institute for Eye Diseases in Belgrade over a three-year period (March 2005 to March 2008. Results. Visual acuity reduction (≤ 0.3 was found in 161/237 (67.9% patients, 85 of whom had visual acuity of ≤ 0.1 later. Working age patients (up to 60 years of age most often suffered from uveitis (173/237; 73%. The highest number of patients with visual loss was in the group suffering from panuveitis (77/94; 81.91%. The age of onset of uveitis and sex have no statistically significant influence on visual loss. The most common causes of visual loss (34/161; 21.1% were cystoid macular oedema (CMO (43/161; 26.7%, cataract (28/161; 17.39% and combination of CMO and cataract. Conclusion. The risk factors for severe visual loss (≤ 0.1 are panuveitis, bilateral inflammation, prolonged visual reduction and a significant number of relapses. The main causes of visual loss in 65.2% of our patients were CMO and cataract.

Full Text Available Resident and infiltrated macrophages play relevant roles in uveitis as effectors of innate immunity and inductors of acquired immunity. They are major effectors of tissue damage in uveitis and are also considered to be potent antigen-presenting cells. In the last few years, experimental animal models of uveitis have enabled us to enhance our understanding of the leading role of macrophages in eye inflammation processes, including macrophage polarization in experimental autoimmune uveoretinitis and the major role of Toll-like receptor 4 in endotoxin-induced uveitis. This improved knowledge should guide advantageous iterative research to establish mechanisms and possible therapeutic targets for human uveitis resolution.

Uveitis is narrow-defined inflammation of the uvea, also clinically include all inflammatory conditions in the eye. Uveitis may occur as a consequence of various causes and background, such as autoimmune diseases, infections, and hematopoietic malignancy. We have to treat uveitis not only controlling the inflammation but also maintaining up the visual function of the eye because the most uveitis is chronic and relapsing inflammatory disorder. Behçét's disease is a systemic disease and results in loss of vision without adequate treatment. Behçét's disease was a representative of vision loss uveitis because Behçét's patient usually had treatment resistance of conventional treatment, such as colchicine and cyclosporine. However, biological therapy with TNF-α, which started from 2007, has revolutionized the treatment strategy of Behçét's disease. It is not too much to say that Behçét's patient is free from fear of vision loss by the dramatic decrease of ocular attach. Biological therapy is not approved as a treatment of uveitis except Behçét's disease. Some protracted cases of Sarcoidosis and Vogt-Koyanagi-Harada disease are resistant to corticosteroid therapy and require new treatment. In this review, we discuss the pathophysiology of uveitis and report new treatment of Behçét's disease by biological therapy.

The purpose of this study was to compare the histologic features and cytokine profiles of experimental autoimmune uveitis (EAU) and a primed mycobacterial uveitis (PMU) model in rats. In Lewis rats, EAU was induced by immunization with interphotoreceptor binding protein peptide, and PMU was induced by immunization with a killed mycobacterial extract followed by intravitreal injection of the same extract. Clinical course, histology, and the cytokine profiles of the aqueous and vitreous were compared using multiplex bead fluorescence immunoassays. Primed mycobacterial uveitis generates inflammation 2 days after intravitreal injection and resolves spontaneously 14 days later. CD68+ lymphocytes are the predominant infiltrating cells and are found in the anterior chamber, surrounding the ciliary body and in the vitreous. In contrast to EAU, no choroidal infiltration or retinal destruction is noted. At the day of peak inflammation, C-X-C motif ligand 10 (CXCL10), IL-1β, IL-18, and leptin were induced in the aqueous of both models. Interleukin-6 was induced 2-fold in the aqueous of PMU but not EAU. Cytokines elevated in the aqueous of EAU exclusively include regulated on activation, normal T cell expressed and secreted (RANTES), lipopolysaccharide-induced CXC chemokine (LIX), growth-related oncogene/keratinocyte chemokine (GRO/KC), VEGF, monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1α (MIP-1α), and IL-17A. In the vitreous, CXCL10, GRO/KC, RANTES, and MIP-1α were elevated in both models. Interleukin-17A and IL-18 were elevated exclusively in EAU. Primed mycobacterial uveitis generates an acute anterior and intermediate uveitis without retinal involvement. Primed mycobacterial uveitis has a distinct proinflammatory cytokine profile compared with EAU, suggesting PMU is a good complementary model for study of immune-mediated uveitis. CXCL10, a proinflammatory cytokine, was increased in the aqueous and vitreous of both models and may be a

Uveitis associated with juvenile idiopathic arthritis.

Sen, Ethan S; Dick, Andrew D; Ramanan, Athimalaipet V

2015-06-01

Uveitis is a potentially sight-threatening complication of juvenile idiopathic arthritis (JIA). JIA-associated uveitis is recognized to have an autoimmune aetiology characterized by activation of CD4(+) T cells, but the underlying mechanisms might overlap with those of autoinflammatory conditions involving activation of innate immunity. As no animal model recapitulates all the features of JIA-associated uveitis, questions remain regarding its pathogenesis. The most common form of JIA-associated uveitis is chronic anterior uveitis, which is usually asymptomatic initially. Effective screening is, therefore, essential to detect early disease and commence treatment before the development of visually disabling complications, such as cataracts, glaucoma, band keratopathy and cystoid macular oedema. Complications can result from uncontrolled intraocular inflammation as well as from its treatment, particularly prolonged use of high-dose topical corticosteroids. Accumulating evidence supports the early introduction of systemic immunosuppressive drugs, such as methotrexate, as steroid-sparing agents. Prospective randomized controlled trials of TNF inhibitors and other biologic therapies are underway or planned. Future research should aim to identify biomarkers to predict which children are at high risk of developing JIA-associated uveitis or have a poor prognosis. Such biomarkers could help to ensure that patients receive earlier interventions and more-potent therapy, with the ultimate aim of reducing loss of vision and ocular morbidity.

[New etiological concepts in uveitis].

Science.gov (United States)

Bodaghi, B

2005-05-01

Uveitis remains an important cause of visual impairment, particularly in young patients. Idiopathic forms of intraocular inflammation should no longer be regarded as a presumed clinical entity, and the ophthalmologist must reconsider the specific etiology of primary uveitis when the clinical examination does not yield a definitive diagnosis or when the course of the disease on corticosteroids remains atypical. Laboratory tests based on serum analysis have limited value and should not be considered as diagnostic proof in different clinical presentations. The diagnostic management of infectious uveitis has been greatly improved by the use of molecular techniques applied to ocular fluids and tissues. Polymerase chain reaction (PCR) technology is a powerful tool that should be proposed in atypical cases of uveitis or retinitis of unclear but potentially infectious origin. This strategy is a major step before using unconventional and new immunomodulatory agents such as anti-TNF-alpha molecules. Under strict experimental conditions including adequate testing to rule out a possible contamination, PCR and its variants have changed our practical approach to intraocular inflammatory disorders and have provided new details for the understanding of infectious uveitis. The concept of pathogen-induced intraocular inflammation can be revisited in the light of molecular data obtained after anterior chamber paracentesis or diagnostic vitrectomy.

Uveitis is composed of a diverse group of disease entities, which in total has been estimated to cause approximately 10% of blindness. Uveitis is broadly classified into anterior, intermediate, posterior and panuveitis based on the anatomical involvement of the eye. Anterior uveitis is, however, the commonest form of uveitis with varying incidences reported in worldwide literature. Anterior uveitis can be very benign to present with but often can lead to severe morbidity if not treated...

We report our results with systemic Etanercept in patients with juvenile idiopathic arthritis in a joint ophthalmology-rheumatology clinic at a tertiary hospital. Patients with JIA on Etanercept were identified from a dedicated uveitis database. A retrospective review of electronic and paper-based patient records was performed. 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. 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.

Five bone marrow and 5 heart transplant recipients were followed for a mean of 4.2 months post-transplantation. All the patients were seropositive for cytomegalovirus (CMV before admission and 80% experienced one or more recurrences during the observation period. Of the 12 episodes of CMV infection, that were identified in this study, 83% were accompanied by clinical or laboratory abnormalities. However, there was only one case of severe disease. The overall incidence of infection for herpes simplex (HSV was 50%. Although most of HSV reactivations were oral or genital, one case of HSV hepatitis occurred. One of the 6 episodes of HSV infections that were treated with acyclovir showed an unsatisfactory response and was successfully managed with ganciclovir. All the individuals had anti-varicella zoster virus antibodies, but none of them developed infection. The study emphasizes the importance of active diagnostic surveillance of herpesvirus infections in transplant patients.

Full Text Available Objective. Uveitis is a severe manifestation of rheumatic diseases since it can lead to visual impairment and even blindness. Ocular involvement is frequently a clinical challenge because its occurrence often requires changes of the therapeutic strategy. There are growing evidence that tumor necrosis factor α (TNFα inhibitors may be an effective treatment of refractory uveitis. Purpose of this study was to evaluate the efficacy and safety of TNFα blocking agents in patients with seronegative spondylo-arthropathies (SNSA and Behcet disease (BD associated relapsing uveitis. Methods. Five consecutive patients with chronic or relapsing uveitis were prospectively studied. Two patients with SNSA had recurrent anterior uveitis and three patients had BD associated uveitis (one anterior, two posterior uveitis. All of the patients were taking systemic and topical corticosteroids and three of them were also treated with DMARDS (methotrexate, cyclosporine, sulphasalazine without clinical benefit. Four patients received infliximab, an anti- TNFα monoclonal antibody, at a dosage of 5 mg/kg body weight and one patient was treated with etanercept, a TNFα receptor p75-Fc fusion protein, at a dosage of 25 mg twice weekly. Results. Both infliximab and etanercept induced a marked improvement in uveitis and none relapse was observed throughout all the study. Systemic corticosteroids were progressively tapered and stopped in all patients. Also methotrexate and sulphasalazine were discontinued, while cyclosporine dose has been reduced by 30% until now. No side effects were observed. Conclusions. Therapy with TNFα blockers, infliximab and etanercept, was effective and safe in the treatment of rheumatic disease associated uveitis. A complete remission was achieved even in patients with severe steroid resistant uveitis. Further controlled studies on larger number of patients are needed to better define the different forms of ocular involvement that can benefit from

To determine the associations of systemic diseases with intermediate uveitis. The medical records of 50 consecutive cases with intermediate uveitis referred to The Eye Center in Riyadh, Saudi Arabia, were reviewed. Age- and sex-matched patients without uveitis served as controls. Patients had complete ophthalmic and medical examinations. There were 27 male and 23 female patients. Mean age was 29 years with a range of 5-62 years. Overall, 21 cases (42%) had systemic disorders associated with intermediate uveitis and 29 cases (58%) had no associated systemic disease. A total of 11 patients (22%) had asthma, 4 (8%) had multiple sclerosis, 3 (6%) had presumed ocular tuberculosis, 1 (2%) had inflammatory bowel disease, 1 (2%) had non-Hodgkin lymphoma and 1 (2%) had sarcoidosis. Evidence of systemic disease was found in 50 (5%) of the 1,000 control subjects. Bronchial asthma was found in 37 patients (3.7 %), multiple sclerosis in 9 patients (0.9%), inflammatory bowel disease in 3 patients (0.3%), and tuberculosis in 1 patient (0.1%). None of the control patients had sarcoidosis or lymphoma. There were statistically significant associations between intermediate uveitis and bronchial asthma (p = 0.0001), multiple sclerosis (p = 0.003) and tuberculosis (p = 0.0005). Bronchial asthma and multiple sclerosis were the most frequently encountered systemic diseases associated with intermediate uveitis in our patient population. Patients with intermediate uveitis should undergo careful history-taking and investigations to rule out associated systemic illness.

Thirty-one paediatric patients with chronic anterior juvenile idiopathic arthritis-related uveitis in 58 eyes and who had been on adalimumab ≥6 months were eligible for the study. Uveitis activity during adalimumab treatment, adalimumab trough levels and anti-adalimumab antibody levels were recorded. Anti-adalimumab antibody levels ≥12 AU /ml were detected in nine patients (29%). This level of anti-adalimumab antibodies was associated with a higher grade of uveitis (puveitis that was not in remission (p=0.001) and with lack of concomitant methotrexate therapy (p=0.043). In patients with anti-adalimumab antibody levels uveitis (p=0.86). Adalimumab treatment might be better guided by monitoring anti-adalimumab antibody formation in treating JIA-related uveitis.

Retrospective retrieval of data on a computerized database incorporating all new referrals to MUC from 1991 to 2013. A total of 3000 new patients with uveitis were seen during a 22-year period. The anatomical types seen were anterior 46%; intermediate 11.1%; posterior 21.8%; and panuveitis 21.1%. The most common diagnoses were Fuchs heterochromic uveitis (11.5% of total), sarcoidosis-related uveitis (9.7%), idiopathic intermediate uveitis (7.9%), idiopathic acute anterior uveitis (7.0%), and toxoplasmosis (6.9%). Syphilis and tuberculosis-associated uveitis increased markedly in frequency during the study period. The uveitis casemix in this region reflects a predominantly white Caucasian population in a temperate country, but with changing characteristics owing to increasing immigration, enhanced diagnostic techniques, changes in referral pattern, and some real changes in disease incidence.

This study was designed to investigate whether the antiinflammatory and antiproliferative activity of oral and intravitreal methotrexate (MTX) suppresses intraocular inflammation in patients with presumed latent syphilitic uveitis and presumed tuberculosis-related uveitis. Interventional prospective study including three cases with presumed latent syphilitic uveitis treated with intravenous penicillin and oral MTX, and two cases with presumed tuberculosis-related uveitis treated with standard antituberculosis therapy and intravitreal MTX injections. Treatment efficacy of all cases was assessed by best-corrected visual acuity, fundus fluorescein angiography, and optical coherence tomography. Four eyes of 3 patients with presumed latent syphilitic uveitis had improved best-corrected visual acuity, suppression of intraocular inflammation, and resolution of cystoid macular edema in 6 months with oral MTX therapy. No recurrence of intraocular inflammation was observed in 6 months to 18 months of follow-up period after cessation of MTX. Two eyes of two patients with presumed tuberculosis-related uveitis showed improved best-corrected visual acuity, suppression of intraocular inflammation, and resolution of cystoid macular edema after intravitreal injections of MTX. No recurrence of intraocular inflammation was observed in 6 months to 8 months of follow-up period after cessation of antituberculous therapy. For the first time in the treatment of presumed latent syphilitic uveitis and presumed tuberculosis-related uveitis, we believe that MTX might have an adjunctive role to suppress intraocular inflammation, reduce uveitic macular edema, and prevent the recurrences of the diseases.

To report the experience of our center with the use of adalimumab (ADA) for the treatment of severe refractory noninfectious paediatric uveitis. The study is a retrospective case series of all paediatric patients with refractory uveitis who were treated with ADA at the Paediatric Uveitis Unit of our center from 2008 to 2015. We present 12 patients (6 Juvenile idiopathic arthritis-associated uveitis, 4 idiopathic panuveitis, 1 early-onset sarcoidosis-associated panuveitis, and 1 intermediate uveitis), with uveitis in 19/24 eyes. Once ADA therapy was started, all the patients presented improved activity according to Standardization of Uveitis Nomenclature (SUN) criteria. Nine out of the 12 patients had structural damage before ADA could be started: cataract (n = 4), glaucoma (n = 2), cystic macular edema (n = 1), exudative retinal detachment (n = 1), and optic disk edema (n = 5). Visual acuity improved or maintained stable in 17/19 affected eyes, and only 2 eyes decreased its visual acuity because of structural damage, which was already present before ADA therapy. In our experience, ADA presents a good safety profile and is efficacious in the treatment of paediatric patients with different forms of refractory noninfectious uveitis.

Uveitis refers to the presence of intraocular inflammation, and as a strict definition compromises the iris and ciliary body anteriorly and the choroid posteriorly (the uvea). Untreated, uveitis can lead to visual loss or blindness. The etiology of uveitis can include both infectious and noninfectious (usually immune-mediated) causes, the latter of which are often mediated predominantly by Th1 CD4 + T-cells that secrete proinflammatory cytokines. Tumor necrosis factor-alpha (TNF-α) is a proinflammatory cytokine involved in the pathogenesis of uveitis, which at high concentrations can cause excess inflammation and tissue damage. Adalimumab is a recombinant human IgG1 monoclonal antibody specific for human TNF-α. Historically, corticosteroids and methotrexate were used to treat uveitis; however, newer biologic agents such as adalimumab have revolutionized therapy for noninfectious uveitis. Adalimumab has shown efficacy in treating refractory uveitis in multiple settings, including idiopathic disease, juvenile idiopathic arthritis, sarcoidosis, Behçets disease, and uveitis secondary to spondyloarthropathies, among several other noninfectious uveitis conditions. In this paper, we will review the profile of adalimumab, the role of TNF-α in uveitis, discuss safety data, and summarize key articles evaluating the efficacy of adalimumab in treating uveitis secondary to the most commonly associated autoimmune diseases.

El curso natural de esta enfermedad está relacionado con una neuropatía periférica denominada neuropatía leprótica, la cual es responsable de la aparición de discapacidades en ojos, manos y pies. Se realizó una búsqueda estructurada en la base de datos de Pubmed y OVID utilizando los siguientes términos MeSH : lepra, neuropatía, nervio periférico, célula de Schwann, discapacidad, biomarcadores. El 83,8 % de los artículos referenciados en esta revisión fueron seleccionados a través de esta búsqueda. El daño neural en lepra es una patología en la que intervienen múltiples mecanismos fisiopatógenicos, que incluyen: la respuesta inmune del hospedero, la interacción de M. leprae a diferentes ligandos en las células Schwann, lo que permite la activación de vías de señalización celular que inducen inflamación, desmielinización y daños a nivel del axón, que se traducen en discapacidad sensitiva y motora en el paciente con lepra. Pero a pesar de que en las últimas décadas se han realizado avances importantes en el entendimiento de esta neuropatía, esto no se ha visto reflejado en herramientas o biomarcadores que sean útiles en la detección temprana del daño periférico causado por la lepra.

Background Typically juvenile idiopathic arthritis (JIA)-associated uveitis (further referred as ‘JIA-uveitis’) has its onset in childhood, but some patients suffer its, sometimes visual threatening, complications or ongoing disease activity in adulthood. The objective of this study was to analyze uveitis activity, complications and visual prognosis in adulthood. Methods In this multicenter study, 67 adult patients (129 affected eyes) with JIA-uveitis were retrospectively studied for best corrected visual acuity, visual fields, uveitis activity, topical/systemic treatments, ocular complications, and ocular surgeries during their 18th, 22nd and 30th year of life. Because treatment strategies changed after the year 1990, outcomes were stratified for onset of uveitis before and after 1990. Results Sixty-two of all 67 included patients (93%) had bilateral uveitis. During their 18th life year, 4/52 patients (8%) had complete remission, 28/52 (54%) had uveitis activity and 37/51 patients (73%) were on systemic immunomodulatory treatment. Bilateral visual impairment or legal blindness occurred in 2/51 patients (4%); unilateral visual impairment or legal blindness occurred in 17/51 patients (33%) aged 18 years. The visual prognosis appeared to be slightly better for patients with uveitis onset after the year 1990 (for uveitis onset before 1990 (n = 7) four patients (58%) and for uveitis onset after 1990 (n = 44) 13 patients (30%) were either visual impaired or blind). At least one ocular surgery was performed in 10/24 patients (42%) between their 18th and 22nd year of life. Conclusions Bilateral visual outcome in early adulthood in patients with JIA-uveitis appears to be fairly good, although one third of the patients developed one visually impaired or blind eye. However, a fair amount of the patients suffered from ongoing uveitis activity and needed ongoing treatment as well as surgical interventions. Awareness of these findings is important for ophthalmologists and

Full Text Available Stephen J Balevic, C Egla Rabinovich Department of Pediatric Rheumatology, Duke University Medical Center, Durham, NC, USA Abstract: Uveitis refers to the presence of intraocular inflammation, and as a strict definition compromises the iris and ciliary body anteriorly and the choroid posteriorly (the uvea. Untreated, uveitis can lead to visual loss or blindness. The etiology of uveitis can include both infectious and noninfectious (usually immune-mediated causes, the latter of which are often mediated predominantly by Th1 CD4+ T-cells that secrete proinflammatory cytokines. Tumor necrosis factor-alpha (TNF-α is a proinflammatory cytokine involved in the pathogenesis of uveitis, which at high concentrations can cause excess inflammation and tissue damage. Adalimumab is a recombinant human IgG1 monoclonal antibody specific for human TNF-α. Historically, corticosteroids and methotrexate were used to treat uveitis; however, newer biologic agents such as adalimumab have revolutionized therapy for noninfectious uveitis. Adalimumab has shown efficacy in treating refractory uveitis in multiple settings, including idiopathic disease, juvenile idiopathic arthritis, sarcoidosis, Behçets disease, and uveitis secondary to spondyloarthropathies, among several other noninfectious uveitis conditions. In this paper, we will review the profile of adalimumab, the role of TNF-α in uveitis, discuss safety data, and summarize key articles evaluating the efficacy of adalimumab in treating uveitis secondary to the most commonly associated autoimmune diseases.Keywords: uveitis, autoimmune disease, adalimumab, TNF-α

To determine the incidence of and associated risk factors for uveitis after cataract surgery. A total of 17,757 eyes were identified and records of 42 eyes that developed uveitis and 2320 eyes that did not were reviewed. Postsurgical uveitis was defined as persistent inflammation for ≥ 6 months after surgery. Forty-two eyes of 35 patients developed uveitis (0.24%). Eleven patients underwent consecutive cataract surgery but developed unilateral uveitis, and intraoperative complications occurred in 55% of uveitic eyes compared to 0% in fellow eyes (p < 0.05). Median duration of inflammation was 8 and 11.5 months in eyes with and without vitrectomy (p < 0.05). Intraocular complications occurred in 44 and 8.3% of eyes that did and did not develop uveitis, respectively (p = 0.01). Postsurgical uveitis developed after approximately 1 in 400 cataract surgeries and occurred more frequently in eyes experiencing intraoperative complications.

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

Signs and symptoms of pigment dispersion may be confused with those of acute anterior uveitis. This case series is intended to aid the ophthalmologist in the clinical differentiation between these two disorders. The authors present a series of 6 patients with pigment dispersion who were initially diagnosed as having acute anterior uveitis and treated with anti-inflammatory medication, including corticosteroids. The patients were referred for a second opinion due to poor or no response to therapy and were found to have pigment dispersion instead of uveitis. Symptoms of pigment dispersion may consist of blurred vision, redness, ocular pain, and photophobia, all of which are also symptoms of acute anterior uveitis. These symptoms, plus the fact that pigment floating in the aqueous humor can be mistaken for inflammation, make diagnosis challenging. Moreover, the possible co-existence of true anterior uveitis and pigment dispersion makes the diagnosis and treatment more difficult.

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.

Sex and Reproduction in the Transmission of Infectious Uveitis

Directory of Open Access Journals (Sweden)

2014-01-01

Full Text Available Current data permit only speculations regarding sex differences in the prevalence of infectious uveitis between women and men because uveitis case surveys do not uniformly report gender data. Differences in prevalence that are reported in the literature could relate to simple differences in the number of women and men at risk for infection or to biological differences between men and women. Compared to other types of uveitis, infectious uveitis may be directly related to occupational exposures or sexual behaviors, which differ between women and men, and may mask actual biological differences in susceptibility to ocular manifestations of the infection and its prognosis. In infectious uveitis for which there is no element of sexual transmission and data is available, prevalence of ocular disease is roughly equal between women and men. Women also have a unique relationship with infectious uveitis in their role as mothers. Vertical transmission of infections such as herpes simplex, toxoplasmosis, and cytomegalovirus can produce severe chorioretinitis in neonates.

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.

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.

There is no updated information on epidemiology and cost of management of non infectious uveitis (NIU) in Spain. This study assessed the frequency of various types of uveítis as well as associated costs of resources used in their management. NIU epidemiological data and direct costs were collected from a literature search. This was complemented with consensus information from 2 expert panel meetings and data from questionnaires to ophthalmologists and rheumatologists, experts on these conditions. Healthcare resources costs were obtained from the Oblikue database, from a medical society and from approved drug prices in Spain. During 2011 the estimate number of NIU was 9,398 (45% male, 70% aged 16-65 years). Incidence per type of uveitis was: acute anterior uveitis (AAU) 55%; posterior uveitis (PU) and pan-uveitis (PanU) 15% each; adult chronic anterior uveitis, paediatric chronic anterior uveitis and intermediate uveitis 5% each. Among total costs (77,834,282.10€), initial drug therapy was the highest (43,602,359.29€), followed by surgical treatment of complications (8,367,420.43€). With respect to types of uveitis, PanU (26,692,948.29€), PU (22,283,330.50€) and AAU (14,336,755.38€) showed the highest associated costs. Non infectious uveitis is associated to high costs in Spain, both in its diagnosis and in its treatment. Early diagnosis and treatment should allow for substantial savings for the National Health System.

The aim of the study was to assess the clinical features and treatment responses in Iranian patients with sarcoid uveitis. A retrospective review of patients diagnosed with sarcoid uveitis from 1996 to 2010 was performed in a referral clinic in Tehran, Iran. Demographic and clinical features of patients, treatment modalities and therapeutic responses, and outcomes were recorded. Sixty-six eyes from 36 patients were studied. Twenty cases had biopsy-proven sarcoidosis. Mean duration of follow-up was 44.7 ± 45 months (range 3-175). Thirty-six eyes (54.5 %) had intermediate uveitis, 25 (37.9 %) panuveitis, and 5 (7.6 %) anterior uveitis. Twenty patients (55.5 %) responded to both systemic and/or topical corticosteroids, and 16 (44.4 %) required immunomodulatory drugs for control of uveitis. All of the patients finally responded to treatment in the form of inflammation reduction and/or vision improvement. The average time interval before initial clinical response following treatment was 3.2 ± 3 months (range 1-72). This study disclosed a higher predominance of females and intermediate form of uveitis in Iranian patients with sarcoid uveitis. Use of immunomodulatory drugs combined with corticosteroids resulted in good visual outcome and control of uveitis with a possible fewer corticosteroid side effects.

Full Text Available A compactação vem-se tornando um dos principais impactos causados ao solo pelas atividades de colheita florestal mecanizada. O peso e movimentação das máquinas no momento do corte e extração da madeira, aliados à condição de umidade do solo imprópria para tal, são as principais causas da degradação estrutural do solo, verificada, principalmente, por alterações em suas propriedades físicas. Nesse sentido, este trabalho visou identificar a compactação causada ao solo devido às operações de colheita florestal de Pinus taeda L. realizada em três diferentes níveis de umidade do terreno. O estudo foi realizado em área de uma empresa florestal localizada no Paraná sobre Latossolo Vermelho. Os tratamentos foram compostos pela interação de três fatores, sendo eles: umidade (colheita em dia chuva, três e sete dias após a chuva, operações de colheita (com passagem de máquinas, sem passagem/eventual queda de árvores e estaleiro, e a ocasião de coleta (antes e depois da colheita. A biomassa residual da colheita florestal foi essencial para minimizar a compactação do solo causada pelo tráfego das máquinas que foi próxima da máxima. A gradação de umidade representada pela colheita em diferentes números de dias após uma chuva não influenciou, de maneira diferenciada, a compactação do solo. Entretanto, as operações de colheita impactaram o solo até a profundidade de 10 cm, causando a compactação nas linhas de tráfego das máquinas, enquanto as demais operações não provocaram alterações na densidade, macroporosidade e resistência à penetração.

Uveitis is an inflammatory disorder involving inflammation of the uveal tract. It is classified as anterior, intermediate, posterior or panuveitis, depending on the part of eye affected by the inflammatory process. In children, noninfectious, chronic uveitis is a relatively uncommon but serious disease, with the potential for significant long-term complications and possible blindness. Although frequently associated with an underlying systemic disease, for example, juvenile idiopathic arthritis, a significant number of cases in children show no associated signs or symptoms and are labeled as idiopathic. We reviewed the available literature. Taking into account this evidence, an anti-inflammatory therapy based on an immunomodulatory approach seems a reasonable strategy for noninfectious chronic uveitis, in children as well as in adults. Due to a lack of controlled studies regarding uveitis in children, immunosuppressive strategy is supported only at evidence level III. Our aim is to review the currently available medical strategies for the treatment of childhood sight-threatening chronic uveitis. Uveitis in children can be severe. Methotrexate is the drug of choice for recalcitrant cases, and biologic therapies can be useful in selected situations.

To determine aqueous humor CD4+/CD8+ T-lymphocyte ratio changes in sarcoid and non-sarcoid uveitis with anterior chamber involvement. The case-control study includes 61 patients with either anterior uveitis, intermediate uveitis with anterior spill, or panuveitis. A total of 21 of them were categorized as sarcoid uveitis and 40 as non-sarcoid uveitis according to diagnostic criteria. CD4+/CD8+ ratio in the aqueous humor was determined using flow cytometry. Significantly higher CD4+/CD8+ ratio in the aqueous humor was observed in patients with sarcoid uveitis (6.3 ± 1.4; mean ± SEM) compared to non-sarcoid uveitis (1.6 ± 0.1; mean ± SEM). Whole blood CD4+/CD8+ ratio was not elevated in subjects with sarcoid and non-sarcoid uveitis. Aqueous humor CD4+/CD8+ ratio >3.5 was observed to be associated with sarcoid uveitis (OR 38, 95% CI 7.0-205.2). Increased aqueous humor CD4+/CD8+ ratio in sarcoid uveitis. Immunophenotyping of localized lymphocytosis in aqueous humor could be utilized as an additional confirmatory marker for ocular sarcoidosis.

Herpes simplex-associated uveitis is usually considered a unilateral eye disease, and rarely included in the differential diagnosis whenever there is bilateral involvement. We report three cases of bilateral herpetic anterior uveitis. We evaluated three patients who presented with clinical manifestations of bilateral uveitis suggestive of viral origin. We found intraocular hypertension, cells in the anterior chamber, paralytic mydriasis, iris atrophy with transillumination defects, and variable anterior vitreous cellularity. According to the clinical findings, supported with herpes-specific antibody titers and aqueous humor PCR results in two of them, they were diagnosed with bilateral anterior herpetic uveitis. Our patients were initially misdiagnosed as having non-infectious uveitis and were treated with immunomodulatory medications, which could have favored the extension of infection bilaterally. Although uncommon, bilateral herpetic uveitis should always be considered in the differential diagnoses, when patients present with hypertensive uveitis in both eyes.

Uveitis is a term used to describe inflammation of uvea, which is the middle layer of eye. It is an important cause of blindness in children in both developed and developing countries. Delayed diagnosis, inadequate treatment and risk of amblyopia are some of the factors that are unique to childhood uveitis and are responsible for significant morbidity seen with this disease.

Adalimumab, an inhibitor of tumor necrosis factor-alpha (TNFα), is the only systemic non-corticosteroid agent which has been approved by the US Food and Drug Administration (FDA) for the treatment of non-infectious uveitis. Areas covered: The aim of this review is to summarize the research which demonstrated the effectiveness of adalimumab in the treatment of intraocular inflammation and helped to establish its side effect profile, ultimately leading to its FDA approval. Expert commentary: Adalimumab is a useful second-line agent in the treatment of non-infectious uveitis. While it is only approved in the United States for use in intermediate, posterior, and panuveitis in adults, I find it to be effective in off-label treatment of pediatric uveitis and scleritis as well.

Full Text Available Uveitis is the third leading cause of blindness in developed countries. Currently, the most widely used treatment of non-infectious uveitis is corticosteroids. Posterior uveitis and macular edema can be treated with intraocular injection of corticosteroids, however, this is problematic in chronic cases because of the need for repeat injections. Another option is systemic immunosuppressive therapies that have their own undesirable side effects. These systemic therapies result in a widespread suppression of the entire immune system, leaving the patient susceptible to infection. Therefore, an effective localized treatment option is preferred. With the recent advances in bioengineering, biodegradable polymers that allow for a slow sustained-release of a medication. These advances have culminated in drug delivery implants that are food and drug administration (FDA approved for the treatment of non-infectious uveitis. In this review, we discuss the types of ocular implants available and some of the polymers used, implants used for the treatment of non-infectious uveitis, and bioengineered alternatives that are on the horizon.

To investigate the clinical characteristics of childhood uveitis leading to visual impairment or blindness. In this descriptive study, we reviewed data from the medical records of 58 children with visual impairment or blindness due to childhood uveitis, which were seen at an institute for visually impaired patients (Bartiméus) between January 1981 and December 2012, in a retrospective, cross-sectional manner. Thirty-two of the 58 children (55%) were visually impaired and 26 (45%) were legally blind. Uveitis was posterior in 76% of all cases. Infectious uveitis represented 74% of all cases, of which 86% was congenital. Five patients (9%) had uveitis related to a systemic disease, and ten patients (17%) had idiopathic uveitis. There was a decrease in infectious causes over the last decades (p = 0.04) and an increase in idiopathic uveitis (p children with posterior uveitis remained constant. There was an overall decrease in the number of children with uveitis referred to Bartiméus. The number of ocular complications at the time of intake was higher in children with acquired disease compared with congenital diseases (p children with non-infectious uveitis compared with infectious uveitis (p = 0.04). Most comorbidities that were noted were seen in children with infectious uveitis. Most patients suffering from visual impairment or blindness due to childhood uveitis had posterior and/or infectious uveitis, mostly congenital. There is a shift in causes which shows a decrease in infectious causes and an increase in idiopathic causes. © 2014 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

To investigate the prevalence of Toxoplasma gondii and Toxocara canis in patients with uveitis. Patients with uveitis were examined. Serum antibodies to T. gondii and T. canis were tested by using the enzyme-linked immunosorbent assay. Polymerase chain reaction (PCR) was done using blood and aqueous humor (AH). Ninety-eight patients were enrolled. Mean age was 43.5 ± 13.2 years. Six patients were seropositive for T. gondii with the following pattern: anterior uveitis, 1; posterior uveitis with retinitis, 2; pan uveitis, 2. One patient had a positive PCR result for T. gondii in AH, who showed panuveitis. Twenty-three patients were positive to serum IgG for T. canis with the following clinical manifestation: granuloma, 6; pigmented scar, 3; vitritis, 6--but none were PCR positive. T. gondii and T. canis are still important causes of uveitis. Ocular toxocariasis is not an uncommon cause of uveitis, even in adults.

To evaluate the incidence and prevalence of uveitis and associated risk factors in South Korea. For this retrospective national cohort study, approximately 1 000 000 Korean residents were randomly selected from the Korean National Health Insurance Service database. Uveitis was defined according to the Korean Classification of Diseases. The uveitis incidence and prevalence were calculated. Sociodemographic factors and comorbidities associated with uveitis were evaluated via Cox proportional regression models. A total of 1 094 440 subjects were evaluated over 7 051 346 person-years (mean follow-up: 6.44 years). Overall, 7447 newly developed uveitis cases were identified during the period of 2007-2013; the average incidence of uveitis was 10.6 per 10 000 person-years (95% CI 10.3 to 10.8). The average incidences of anterior and non-anterior uveitis were 9.0 and 1.5 per 10 000 person-years, respectively. The prevalence rates of uveitis, anterior uveitis and non-anterior uveitis were 17.3, 15.0 and 2.3 per 10 000 persons, respectively, during the period of 2007-2013. Increasing age, male sex, residing in a relatively rural area and high income were associated with uveitis, along with Behçet's disease, juvenile idiopathic arthritis, ankylosing spondylitis, systemic lupus erythematous, ulcerative colitis and tuberculosis. The overall incidence of uveitis in Korea was similar to those reported in Taiwan and the USA. Despite a potentially inaccurate disease definition, claims data may be useful for monitoring the substantial uveitis burden in South Korea. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Full Text Available Objectives: To determine the prevalence of vitreomacular interface (VMI disorders in patients with Behçet’s uveitis and assess the relationship between VMI disorders and clinical characteristics. Materials and Methods: The macular optical coherence tomography (OCT images of 160 eyes of 96 patients with Behçet’s uveitis who were being followed in the Uvea-Behçet’s clinic were assessed retrospectively for VMI disorders including posterior vitreous detachment (PVD, epiretinal membrane (ERM, vitreomacular adhesion (VMA, vitreomacular traction (VMT, full-thickness macular hole (FTMH, lamellar hole (LH and pseudohole. Results: Twenty-four patients (25% with unilateral and 72 patients with bilateral uveitis were included in the study. Six (30% of 20 eyes with anterior uveitis and 57 (40.7% of 140 eyes with posterior uveitis, in total 63 (39.4% eyes of 160 eyes had at least one VMI disorder. PVD was detected in 4 eyes (2.5%, ERM in 48 eyes (30%, VMA in 12 eyes (7.5%, and LH in 1 eye (0.6%. None of the eyes had VMT, FTMH, or pseudohole. ERM was detected in 13 eyes (8.1% on fundus examination and 48 (30% eyes by OCT (p=0.001. VMI was detected in 12 (50% of 24 eyes with prior intraocular surgery and 51 (37.5% of 136 eyes without. The mean duration of uveitis was 7.3±5.8 years in patients with VMI disorders and 5.8±7.7 years in patients without (p=0.04. There was no relation between VMI disorders and anatomic location of uveitis, history of past ocular surgery, number of ocular/periocular steroid injections, or visual acuity. Conclusion: VMI disorders are common in patients with Behçet’s uveitis. Their frequency increases with the duration of uveitis. OCT is more sensitive than fundus examination in the detection of VMI disorders.

To compare the benefits of fluocinolone acetonide implant therapy versus systemic corticosteroid therapy supplemented (when indicated) with immunosuppression for intermediate uveitis, posterior uveitis, and panuveitis. Additional follow-up of a randomized comparative effectiveness trial cohort. Two hundred fifty-five patients with intermediate uveitis, posterior uveitis, or panuveitis randomized to implant or systemic therapy. Best-corrected visual acuity (BCVA), visual field mean deviation (MD), activity of uveitis, and presence of macular edema (per reading center grading) ascertained prospectively. Trial participants were followed-up for 54 months from original randomization. The visual function trajectory in uveitic eyes demonstrated a similar (P = 0.73) degree of modest (not statistically significant) improvement from baseline to 54 months in both groups (mean improvement in BCVA at 54 months, 2.4 and 3.1 letters in the implant and systemic groups, respectively). Many had excellent initial visual acuity, limiting the potential for improvement. The mean automated perimetry MD score remained similar to baseline throughout 48 months of follow-up in both groups. Overall control of inflammation was superior in the implant group at every time point assessed (P treatment within the first 6 months, the systemic group gradually improved over time such that the proportions with macular edema converged in the 2 groups by 36 months and overlapped thereafter (P = 0.41 at 48 months). Visual outcomes of fluocinolone acetonide implant and systemic treatment for intermediate uveitis, posterior uveitis, and panuveitis were similarly favorable through 54 months. The implant maintained a clear advantage in controlling inflammation through 54 months. Nevertheless, with systemic therapy, most patients also experienced greatly improved inflammatory status. Macular edema improved equally with longer follow-up. Based on cost effectiveness and side-effect considerations, systemic

2013-05-01

The tubulo-interstitial nephritis and uveitis (TINU) syndrome, first described in 1975, is a rare disease most probably of autoimmune origin that is characterized by unilateral or bilateral uveitis and tubulointerstitial nephritis. Most patients are adolescents and it is sometimes associated with other autoimmune diseases, such as spondyloarthritis, rheumatoid arthritis and hyperthyroidosis. This article reports the case of a 43-year-old female patient who presented with refractory recurrent bilateral uveitis despite therapy with high doses of corticosteroids in combination with cyclosporin. When the patient was referred to this hospital for rheumatological examination after almost 1 year of therapy, mild renal insufficiency and proteinuria were found. The kidney biopsy revealed interstitial nephritis, partly crescent-shaped and partly chronic. A diagnosis of TINU syndrome was made and treatment with adalimumab in combination with methotrexate was started. The favorable clinical outcome indicated that tumor necrosis factor (TNF) alpha may play an important role in the pathogenesis of TINU syndrome.

Treatment of Juvenile Idiopathic Arthritis-Associated Uveitis.

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

Immunosuppressive Treatment of Non-infectious Uveitis: History and Current Choices.

Science.gov (United States)

Zhao, Chan; Zhang, Meifen

2017-04-10

Non-infectious uveitis is one of the leading causes of preventable blindness worldwide. Long-term immunosuppressive treatment is generally required to achieve durable control of inflammation in posterior and panuveitis. Although systemic corticosteroids have been the gold standard of immunosup- pressive treatment for uveitis since first introduced in 1950s, its side effects of long-term use often warrant an adjuvant treatment to reduce the dosage/duration of corticosteroids needed to maintain disease control. Conventional immunosuppressive drugs, classified into alkylating agent, antimetabolites and T cell inhibitors, have been widely used as corticosteroid-sparing agents, each with characteristic safety/tolerance profiles on different uveitis entities. Recently, biologic agents, which target specific molecules in immunopathogenesis of uveitis, have gained great interest as alternative treatments for refractory uveitis based on their favorable safety and effectiveness in a variety of uveitis entities. However, lack of large randomized controlled clinical trials, concerns about efficacy and safety of long-term usage, and economic burden are limiting the use of biologics in non-infectious uveitis. Local administration of immunosuppressive drugs (from corticosteroids to biologics) through intraocular drug delivery systems represent another direction for drug development and is now under intense investigation, but more evidences are needed to support their use as regular alternative treatments for uveitis. With the numerous choices belonging to different treatment modalities (conventional immunosuppressive agents, biologics and local drug delivery systems) on hand, the practice patterns have been reported to vary greatly from center to center. Factors influence uveitis specialists' choices of immunosuppressive agents may be complex and may include personal familiarity, treatment availability, safety/tolerability, effectiveness, patient compliance, cost concerns and

Anna Hospital, Brescia, Italy; 3Eye Clinic, Department of Health Sciences, University of Molise, Campobasso, ItalyAbstract: 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.Keywords: adalimumab, etanercept, infliximab

Full Text Available Experimental autoimmune uveitis (EAU is a T-cell mediated autoimmune disease that targets the neural retina and serves as a model of human uveitis. EAU can be induced against several retinal proteins in rats, mice, and subhuman primates. These include the S-antigen, a major protein in retinal photoreceptor cells; interphotoreceptor retinoid-binding protein (IRBP; and rhodopsin and other antigens of retinal origin. There are many similarities between clinical uveitis and EAU, but the latter differs in being self-limited, and needs adjuvant for disease induction. The experimental disease can be induced only in susceptible animal strains. Use of the EAU model has helped investigators understand the pathophysiology of the disease and to evaluate disease-modifying strategies, which could be applied in the clinic. There has been significant progress in this field during last decade, but much more understanding is needed before the knowledge can be transferred to clinical practice. A deeper understanding of the immune mechanisms involved in the EAU model may lead to the development of new therapeutic approaches targeted at various components of the immune response by immunomodulation to control uveitis. This review summarises the evidence from the EAU model, which could be of relevance to the clinical management of patients with uveitis.

Uveitis is a heterogeneous collection of diseases with polygenic and environmental influences. This heterogeneity presents challenges in trial design and selection of end points. Despite the multitude of causes, therapeutics targeting common inflammatory pathways are effective in treating diverse forms of uveitis. These treatments, including corticosteroids and immunomodulatory agents, although often effective, can have untoward side effects, limiting their utility. The search for drugs with equal or improved efficacy that are safe is therefore paramount. A mechanism-based approach is most likely to yield the future breakthroughs in the treatment of uveitis. We review the literature and provide examples of the nuances of immune regulation and dysregulation that can be targeted for therapeutic benefit. As our understanding of the causes of uveitis grows we will learn how to better apply antibodies designed to block interaction between inflammatory cytokines and their receptors. T-lymphocyte activation can be targeted by blocking co-stimulatory pathways or inhibiting major histocompatibility complex protein interactions. Furthermore, intracellular downstream molecules from cytokine or other pathways can be inhibited using small molecule inhibitors, which have the benefit of being orally bioavailable. An emerging field is the lipid-mediated inflammatory and regulatory pathways. Alternatively, anti-inflammatory cytokines can be provided by administering recombinant protein, and intracellular "brakes" of inflammatory pathways can be introduced potentially by gene therapy. Novel approaches of delivering a therapeutic substance include, but are not limited to, the use of small interfering RNA, viral and nonviral gene therapy, and microparticle or viscous gel sustained-release drug-delivery platforms.

Full Text Available Concurrence of interstitial nephritis and uveitis named tubulointestitioal nephritis and uveitis syndrome (TINU are unusual and uncommon presentations of interstitial nephritis. This syndrome is considered after ruling out other differential diagnoses. A-38-year old man presented with acute renal failure and uveitis. The histologic findings of renal biopsy showed acute tubulointestitioal nephritis. The patient had no clinical and paraclinical manifestations of other etiologies of interstitial nephritis and uveitis such as Wegener's granulomatosis , Sjogren's syndrome or sarcoidosis. The diagnosis of TINU-Syndrome was therefore considered. The patient was treated by oral and ophthalmic prednisolone and had a good response to treatment.

Papulonecrotic tuberculids represent an immunological expression of an internal focus of tuberculosis in an individual with a moderate or high degree of immunity. It responds to anti-tuberculosis treatment and is characterized by an eruption of necrotizing papules occurring in symmetrical crops, particularly affecting the elbows, knees, buttocks and face. A case of papulonecrotic tuberculids associated with immune mediated unilateral uveitis is reported in which all investigations were negative for tuberculosis except a strongly positive tuberculin test. There was an excellent response to anti-tuberculosis treatment. The association of immune mediated uveitis with papulonecrotic tuberculids has not been described before. (author)

Uveitis in childhood is a visual threatening disease with a complication rate of more than 75%. Despite extensive research, the etiology of uveitis is still unclear although the general opinion is now that uveitis is a T-cell mediated disease. The purpose of this study was to investigate the profile of cytokines, chemotactic cytokines (chemokines) and soluble adhesion molecules in the aqueous humor (AqH) of children with uveitis in order to identify the factors that control the immune response in the eye. In this clinical laboratory investigation we analyzed, with a multiplex immunoassay, 16 immune mediators in the AqH of 25 children with uveitis and 6 children without uveitis. Increased levels of interleukin-2 (IL-2), IL-6, IL-10, IL-13, IL-18, interferon-gamma, tumor necrosis factor-alpha, soluble intercellular adhesion molecule-1, RANTES, IL-8 and interferon-inducible 10-kDa protein were found in the AqH of children with uveitis compared with controls. No significant differences were found for IL-1 beta, IL-4, IL-12 p-70, soluble vascular cell adhesion molecule 1 and Eotaxin. Lower levels of IL-10 and IL-8 were found in quiet stage uveitis (surgical) samples compared with active uveitis (diagnostic) samples and in samples of patients treated with methotrexate (MTX) compared with samples of patients not treated with MTX. Lower levels of IL-10 were as well found in samples taken during the first 3 months after the diagnosis of uveitis than samples taken later during the disease process. No significant differences were found between patients treated with or without topical or systemic (perioperative and long term) corticosteroids. In conclusion, in children with uveitis, multiple intraocular cytokines, chemokines and soluble adhesion molecules are increased in the AqH regardless of active or inactive inflammation. Whether the IL-8 and IL-10 levels in AqH of children with uveitis are correlated with uveitis activity, early or late phase of the course of the disease

Objectives To evaluate the outcome of TNF-alpha inhibition (anti-TNFα) for pediatric uveitis. Methods We retrospectively assessed children (≤18 years) with non-infectious uveitis receiving anti-TNFα at five uveitis centers and one pediatric-rheumatology center. Incident treatment success was defined as minimal or no uveitis activity at ≥2 consecutive ophthalmological exams ≥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% confidence interval [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 amongst 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-TNFα - independent of the number of immunomodulators previously or concomitantly prescribed. Uveitis re-activated within 12 months of achieving quiescence in 14% of those continuing anti-TNFα (95% CI: 6–31%). The incidence of discontinuation for adverse effects was 8%/year (95% CI: 1–43%). Conclusion Treatment with anti-TNFα was successful and sustained in a majority of children with non-infectious uveitis and treatment-limiting toxicity was infrequent. JIA-associated AU may be especially responsive to anti-TNFα. PMID:23818712

Methods: Retrospective, observational study of uveitis patients seen at the University of Virginia from 1984 to 2014. Results: A total of 442 patients (582 eyes with uveitis were identified and included in the study. The patient population was 57.0% female. Overall, 61.9% were Caucasian and 26.6% were African American. Mean age was 46.8 years. Overall, 11.5% of the eyes had OHT at initial visit, and 7.9% had OHT at final visit (P=0.035. For each additional decade of life, the odds that an eye had OHT were elevated by a factor of 1.15 (95% confidence interval [CI]: [1.02, 1.30], P=0.027 at initial visit and by a factor of 1.15 (95% CI: [1.00, 1.32], P=0.055 at final visit. The odds that an anterior uveitis eye had OHT were greater by a factor of 2.50 (95% CI: [1.22, 5.14], P=0.013 than the odds for a nonanterior uveitis eye at initial visit and greater by a factor of 2.61 (95% CI: [1.24, 5.50], P=0.011 at final visit. For each additional 0.5 logarithm of the minimum angle of resolution increase in initial visual acuity, the odds that an affected eye had OHT were elevated by a factor of 1.18 (95% CI: [1.00, 1.39], P=0.047 at initial visit and 1.23 (95% CI: [0.99, 1.54], P=0.065 at final visit. Overall, 21 of 582 eyes (3.6% were hypotonous initially, while 24 of 582 eyes (4.1% were hypotonous at final follow-up (P=0.631. Conclusion: OHT was associated with increasing age, anterior uveitis, and poor presenting visual acuity. Ocular hypotony was more common in anterior uveitis than in nonanterior uveitis. Fluctuations in intraocular pressure are an important cause of visual impairment in patients with uveitis

Full Text Available PURPOSE: To evaluate anatomical and functional results of 25-gauge transconjunctival sutureless pars plana vitrectomy in patients with uveitis. METHODS: Vitrectomy was performed on 20 eyes with residual vitritis secondary to infectious and noninfectious uveitis. Patients were evaluated 1 week before surgery and after surgery at day 1, week 1, week 4 and week 12. Visual acuity (VA, intraocular pressure, anterior chamber cells and flare and vitreous haze were measured. RESULTS: Mean VA improved from 2.06 ± 0.94 logMAR before surgery to 0.58 ± 0.46 logMAR at week 12 (p<0.05. No case required conversion to standard 20-gauge instrumentation or suture placement, no intraoperative complications were noted. Transient postoperative hypotony was seen in three eyes. One patient with toxoplasmic retinochoroiditis had a relapse during follow-up. CONCLUSION: 25-gauge vitrectomy has proven its efficacy on cleansing vitreous opacities and improving visual acuity on patients with residual vitritis secondary to uveitis with minimal postoperative inflammation and complications.

This review is timely because the outcomes of surgical invention in uveitic eyes with cataract can be optimized with adherence to strict anti-inflammatory principles. All eyes should be free of any cell/ flare for a minimum of 3 months preoperatively. Another helpful maneuver is to place dexamethasone in the infusion fluid or triamcinolone intracamerally at the end of surgery. Recent reports about the choice of intraocular lens material or lens design are germane to the best surgical outcome. Integrating these findings will promote better visual outcomes and allow advancement in research to further refine these surgical interventions in high-risk uveitic eyes. Control of inflammation has been shown to greatly improve postoperative outcomes in patients with uveitis. Despite better outcomes, more scientific research needs to be done regarding lens placement and materials and further research needs to adhere to the standardized reporting of uveitis nomenclature. Future studies should improve postoperative outcomes in eyes with uveitis so that they approach those of eyes undergoing routine cataract procedures.

2007-06-01

Manifestations of uveitis in the sensitive period of childhood can cause amblyopia. In most of the cases band keratopathy, dense cataracts and cyclitic membranes cause deprivation amblyopia. Asymmetrical damage can result in relative amblyopia. Secondary squint can lead to suppression amblyopia. For these reasons every visit during uveitis treatment should be accompanied by a search for amblyogenic factors and visual acuity measurements. In the case of a side difference in the visual acuity, occlusion therapy should be started. The follow-up should not only contain visual acuity measurements but also cycloplegic refraction. Especially when pupil-dilating drugs are necessary for a longer period, bifocals should be prescribed.

Bilateral uveitis and Usher syndrome: a case report.

Science.gov (United States)

Benson, Matthew D; MacDonald, Ian M

2015-03-15

Usher syndrome is a genetically heterogeneous condition and represents the most common cause of inherited combined vision and hearing loss. Deficits manifest as sensorineural hearing loss that typically develops at a young age and retinitis pigmentosa that can lead to peripheral vision loss and night blindness. As a result, this syndrome can have a significant impact on a patient's quality of life. Previous studies have described an association between Usher syndrome and Fuchs' heterochromic iridocyclitis, a form of non-granulomatous uveitis that generally presents in a unilateral manner. We present a rare finding of bilateral uveitis and, to the best of our knowledge, the first report of granulomatous uveitis as a feature in a patient with Usher syndrome. A 45-year-old Caucasian woman with a known history of retinitis pigmentosa presented to our clinic with suspected Usher syndrome, given her report of long-standing hearing loss. Aside from a mild loss in visual acuity, our patient was otherwise asymptomatic. Visual field testing, audiology and electroretinography findings supported the diagnosis of Usher syndrome. With slit lamp examination she was found to have bilateral keratic precipitates, with large, greasy-white, mutton-fat keratic precipitates on the endothelial surface of her left eye. A thorough work-up that included blood tests and imaging was negative for an alternative cause of her uveitis. We present a rare finding of bilateral uveitis and what we believe to be the first reported instance of mutton-fat keratic precipitates and granulomatous uveitis as a feature in a patient with Usher syndrome. By identifying atypical presentations of the disease, we hope to contribute to the range of ophthalmic conditions that may be seen in association with Usher syndrome.

To evaluate whether early treatment with methotrexate (MTX) prevents the onset of uveitis in children with juvenile idiopathic arthritis. The clinical charts of all consecutive patients seen between January 2002 and February 2011 who had a disease duration uveitis had occurred. A total of 254 patients with a median disease duration of 0.3 year were included. Eighty-six patients (33.9%) were treated with MTX, whereas 168 patients (66.1%) did not receive MTX. During the 2-year follow-up, 211 patients (83.1%) did not develop uveitis, whereas 43 patients (16.9%) had uveitis a median of 1.0 year after the first visit. The frequency of uveitis was lower in MTX-treated than in MTX-untreated patients (10.5% vs 20.2%, respectively, P = .049). Survival analysis confirmed that patients treated with MTX had a lower probability of developing uveitis. Early MTX therapy may prevent the onset of uveitis in children with juvenile idiopathic arthritis. Because our study may be affected by confounding by indication, the potential of MTX to reduce the incidence of ocular disease should be investigated in a randomized controlled trial.

To describe the phenotype of the uveitis that accompanies juvenile psoriatic arthritis or psoriasis. Observational case series. Setting: Two university-based referral clinics: 1 in England, 1 in the United States. Five children with uveitis and psoriatic arthritis and 1 with uveitis and psoriasis Observational Procedure: Retrospective chart review. Demographics of subjects such as age and sex; description of ocular and joint disease; surgical and other complications; medical treatment. Five of the 6 children in this series had the onset of disease at or before age 6 (P = .0008 compared to expected age of onset for psoriatic arthritis in childhood). All children in this series had an inadequate response to topical corticosteroids. Most of the children were treated with systemic corticosteroids for many months, yet all of them went on to require methotrexate. Therapy with systemic methotrexate did not suffice, as all the patients also required some form of biologic therapy. Five of 6 had surgeries such as vitrectomy, cataract extraction, or a procedure for glaucoma control. The observations suggest that the uveitis that accompanies juvenile psoriatic arthritis might be a distinct disease that is particularly severe when its onset affects children aged 6 years or younger.

Full Text Available Abstract Background Zoledronic acid is very widely used in patients with metastatic bone disease and osteoporosis. Only one case of bilateral uveitis was recently reported related to its use. Case presentation We report the first case of severe unilateral anterior uveitis in a patient with breast cancer and an intraocular lens. Following zoledronic acid infusion, the patient developed severe and dramatic right eye pain with decreased visual acuity within 24 hours and was found to have a fibrinous anterior uveitis of moderate severity The patient was treated with topical prednisone and atropine eyedrops and recovered slowly over several months. Conclusion Internists, oncologists, endocrinologists, and ophtalmologists should be aware of uveitis as a possible complication of zoledronic acid therapy. Patients should be instructed to report immediately to their physicians and treatment with topical prednisone and atropine eyedrops should be instituted immediately at the onset of symptoms. This report documents anterior uveitis as a complication of zoledronic acid therapy. This reaction could be an idiosyncratic one but further research may shed more light on the etiology.

Background Uveitis is a term used to describe a heterogeneous group of intraocular inflammatory diseases of the anterior, intermediate, and posterior uveal tract (iris, ciliary body, choroid). Uveitis is the fifth most common cause of vision loss in high-income countries, accounting for 5% to 20% of legal blindness, with the highest incidence of disease in the working-age population. Corticosteroids are the mainstay of acute treatment for all anatomical subtypes of non-infectious uveitis and can be administered orally, topically with drops or ointments, by periocular (around the eye) or intravitreal (inside the eye) injection, or by surgical implantation. Objectives To determine the efficacy and safety of steroid implants in people with chronic non-infectious posterior uveitis, intermediate uveitis, and panuveitis. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (Issue 10, 2015), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to November 2015), EMBASE (January 1980 to November 2015), PubMed (1948 to November 2015), Latin American and Caribbean Health Sciences Literature Database (LILACS) (1982 to November 2015), the metaRegister of Controlled Trials (mRCT) (www.controlledtrials.com) (last searched 15 April 2013), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform(ICTRP) (www.who.int/ictrp/search/en).We did not use any date or language restrictions in the electronic search for studies. We last searched the electronic databases on 6 November 2015. We also searched reference lists of included study reports, citation databases, and abstracts and clinical study presentations from professional meetings. Selection criteria We included randomized controlled trials comparing either fluocinolone acetonide (FA) or dexamethasone intravitreal implants with standard

Although rarer than its adult counterpart, non-infectious uveitis remains a significant cause of ocular morbidity in children. Owing to the chronicity of the disorder and when refractory to first-line treatment, namely corticosteroids, systemic immunosuppressive treatment may be required to control the disease. Following a literature search using the keywords 'paediatric uveitis', 'juvenile idiopathic arthritis-associated uveitis', 'immunosuppression' and 'treatment', we reviewed the range and effectiveness of treatments employed in the management of non-infectious, paediatric uveitis. Corticosteroids (topical, periocular, intraocular or systemic) remain the initial drug of choice in ameliorating the signs and symptoms of non-infectious paediatric uveitis. Failure to control the disease and/or failure to reduce the oral dose of prednisolone at least 0.15 mg/kg within 4 weeks often requires additional immunosuppressant therapy. Methotrexate and azathioprine have shown to be effective in the management of juvenile idiopathic arthritis (JIA)-associated uveitis with the former considered the first-line corticosteroid-sparing agent. Biologic therapies are increasingly used earlier in the disease with investigators in the UK currently recruiting patients for the SYCAMORE trial evaluating the efficacy of methotrexate and adalimumab vs methotrexate alone for the treatment for JIA-associated uveitis. Until further randomised controlled trials are conducted, the use of other biologic agents should only be used with an appreciation that there are potentially unknown side-effects and that there is not a full knowledge of their efficacy.

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.

Full Text Available Purpose: To study the patterns of uveitis in the paediatric age group in a referral eye care centre in south India. Materials and Methods: Thirty-one patients 15 years or younger with uveitis, examined in the year 2000, were included in this study. The uveitis was classified according to the anatomical site of ocular involvement and the most probable aetiological factor. The final diagnosis was based on clinical manifestations and results of specific laboratory investigations. Results: A total 31 (6.29% paediatric uveitis cases were seen among the 493 uveitic cases in the year 2000. The male: female ratio was 17:14. Anterior (9 cases, intermediate (9 cases and posterior uveitis (9 cases were seen in equal number. Four patients had panuveitis. Twenty-seven patients had visual acuity of 6/36 or better at presentation. Approximately 25% (8 of 31 patients had cataract secondary to inflammation. Immunosuppressives were administered in 4 patients and one patient required cataract surgery. Conclusion: Uveitis in children comprises approximately 6% of uveitis cases in a referral practice in south India. Anterior, intermediate and posterior uveitis are seen in equal numbers. We recommend that intermediate uveitis be ruled out in all cases of anterior uveitis by careful clinical evaluation including examination under anesthesia (EUA when required.

To analyze visual outcome, effectiveness of various modes of antibiotic treatment, and prognostic factors in patients with serologically proven syphilitic uveitis. The clinical records of 85 patients (139 eyes) diagnosed with syphilitic uveitis between 1984 and 2013 at tertiary centers in The Netherlands were retrospectively analyzed. Mean age was 47 years (range, 27-73 years), 82.4% were male. HIV positivity was found in 28 (35.9%) patients; 13 were newly diagnosed. Most patients had pan (45.9%) or posterior (31.8%) uveitis. On average, logMAR visual acuity (VA) improved significantly from 0.55 at the start of syphilis treatment to 0.34 at 1 month and to 0.27 at 6 months follow-up. Most patients (86.7%) reached disease remission. No differences in efficacy between the various treatment regimens were found. A high logMAR VA at the start of syphilis treatment and a treatment delay of more than 12 weeks were prognostic for a high logMAR VA at 6 months follow-up. Chronicity was not related to any form of treatment, HIV status, or Venereal Disease Research Laboratory test outcome. In this large cohort of 85 patients with syphilitic uveitis, visual outcomes were favorable in the majority of cases. Visual outcome was dependent on VA at the start of syphilis treatment and treatment delay.

To evaluate the efficacy of methotrexate (MTX) and the effect of its withdrawal on relapse rate of uveitis associated with juvenile idiopathic arthritis (JIA). Retrospective case series. Data of 22 pediatric JIA patients who were being treated with MTX for active uveitis were studied retrospectively. Relapse rate after the withdrawal of MTX was established. Anterior chamber (AC) inflammation, topical steroid use during the first year of MTX treatment, and associations of relapses after the withdrawal were evaluated statistically. Duration of MTX treatment and its withdrawal was determined individually in collaboration with a rheumatologist with an intention to continue the treatment for at least 1 year and to withdraw in case of inactivity of uveitis and arthritis. Inactivity of uveitis was defined as the presence of ≤0.5+ cells in the AC. Eighteen patients (18/22; 82%) showed improvement of their uveitis with a significant decrease in activity of AC inflammation after a minimal period of 3 months of MTX treatment. A topical steroid-sparing effect was observed when MTX was administered for a period of 3 to 9 months. MTX was discontinued because of inactive uveitis in 13 patients. In 9 patients (8/13; 69%) a relapse of uveitis was observed after a mean time of 7.5 months (± SD 7.3). Six patients (6/13; 46%) had a relapse within the first year after the withdrawal. Relapse-free survival after withdrawal of MTX was significantly longer in patients who had been treated with MTX for more than 3 years (P = .009), children who were older than 8 years at the moment of withdrawal (P = .003), and patients who had an inactivity of uveitis of longer than 2 years before withdrawal of MTX (P = .033). Longer inactivity under MTX therapy was independently protective for relapses after the withdrawal (hazard ratio = 0.07; 95% confidence interval 0.01-0.86; P = .038), which means that 1-year increase of duration of inactive uveitis before the withdrawal of MTX results in a

To assess the effectiveness of methotrexate (MTX) in the treatment of juvenile idiopathic arthritis (JIA) associated uveitis, which is still one of the most common causes of visual impairment. A retrospective chart review of patients with the diagnosis of uveitis associated with JIA between July 1, 2002, and December 31, 2002. Four hundred sixty-seven patients with JIA were followed. Thirty-eight had uveitis: 31 associated with oligoarticular JIA and 7 with psoriatic JIA. Twenty-five of the 38 patients received MTX; in 23 patients uveitis was the indication for MTX therapy. In the MTX treated group 46/50 eyes had uveitis, the mean (range) age at onset of uveitis was 7.82 years (1.8-15.8), and the mean age at onset of arthritis was 7.25 years (1.25-15.7). MTX treatment was started an average of 11.4 months (0-72) after the onset of uveitis. The mean MTX dose was 15.6 mg/m2. Remission occurred after 4.25 months (1-12). Mean duration of remission was 10.3 months (3-27). The total duration of MTX therapy was 661 months and patients were in remission for 417/661 months. In 6 patients MTX was discontinued after 12 months of remission. Four patients were still in remission after 7.5 months (1-14). MTX seems to be an effective therapy for JIA associated uveitis.

In 18 patients, therapy was discontinued after a short period because of inefficacy or side effects. The activity of uveitis (using Standardized Uveitis Nomenclature [SUN] criteria and clinical examination and arthritis (number of swollen or active joints was evaluated at the start and at end of the study.Results: At the end of the study, uveitis was under good clinical control in two thirds of 54 patients (31% did not need any local treatment and 35% used only 1–2 corticosteroid drops a day, and one third had active uveitis (at least three corticosteroid drops a day. According to SUN criteria, adalimumab treatment for uveitis showed improved activity (a two-fold decrease in uveitis activity in 28% of patients, with a moderate response in 16 patients, no change in a further 16 patients, and worsening activity (a two-fold increase in uveitis activity in 13% of patients. The overall proportion of patients with active arthritis decreased. At the beginning of the study, 69% of patients with uveitis had more than two active joints, and at the end of the study only 27% had active joint disease. In 27 patients with juvenile idiopathic arthritis without uveitis on adalimumab, the number of active joints decreased from 93% to 59%. Systemic corticosteroid treatment could be stopped in 22% of patients with uveitis and in 11% of those without uveitis. Most of the

Gutowski, Michal B; Wilson, Leslie; Van Gelder, Russell N; Pepple, Kathryn L

2017-03-01

We develop a quantitative bioluminescence assay for in vivo longitudinal monitoring of inflammation in animal models of uveitis. Three models of experimental uveitis were induced in C57BL/6 albino mice: primed mycobacterial uveitis (PMU), endotoxin-induced uveitis (EIU), and experimental autoimmune uveitis (EAU). Intraperitoneal injection of luminol sodium salt, which emits light when oxidized, provided the bioluminescence substrate. Bioluminescence images were captured by a PerkinElmer In Vivo Imaging System (IVIS) Spectrum and total bioluminescence was analyzed using Living Image software. Bioluminescence on day zero was compared to bioluminescence on the day of peak inflammation for each model. Longitudinal bioluminescence imaging was performed in EIU and EAU. In the presence of luminol, intraocular inflammation generates detectable bioluminescence in three mouse models of uveitis. Peak bioluminescence in inflamed PMU eyes (1.46 × 105 photons/second [p/s]) was significantly increased over baseline (1.47 × 104 p/s, P = 0.01). Peak bioluminescence in inflamed EIU eyes (3.18 × 104 p/s) also was significantly increased over baseline (1.09 × 104 p/s, P = 0.04), and returned to near baseline levels by 48 hours. In EAU, there was a nonsignificant increase in bioluminescence at peak inflammation. In vivo bioluminescence may be used as a noninvasive, quantitative measure of intraocular inflammation in animal models of uveitis. Primed mycobacterial uveitis and EIU are both acute models with robust anterior inflammation and demonstrated significant changes in bioluminescence corresponding with peak inflammation. Experimental autoimmune uveitis is a more indolent posterior uveitis and generated a more modest bioluminescent signal. In vivo imaging system bioluminescence is a nonlethal, quantifiable assay that can be used for monitoring inflammation in animal models of uveitis.

Full Text Available Abstract Background Uveitis is an autoimmune disease of the eye that refers to any of a number of intraocular inflammatory conditions. Because it is a rare disease, uveitis is often overlooked, and the possible associations between uveitis and extra-ocular disease manifestations are not well known. The aim of this study was to characterize uveitis in a large sample of patients and to evaluate the relationship between uveitis and systemic diseases. Methods The present study is a cross-sectional study of a cohort of patients with uveitis. Records from consecutive uveitis patients who were seen by the Uveitis Service in the Department of Ophthalmology at the Medical University of Vienna between 1995 and 2009 were selected from the clinical databases. The cases were classified according to the Standardization of Uveitis Nomenclature Study Group criteria for Uveitis. Results Data were available for 2619 patients, of whom 59.9% suffered from anterior, 14.8% from intermediate, 18.3% from posterior and 7.0% from panuveitis. 37.2% of all cases showed an association between uveitis and extra-organ diseases; diseases with primarily arthritic manifestations were seen in 10.1% of all cases, non-infectious systemic diseases (i.e., Behçet´s disease, sarcoidosis or multiple sclerosis in 8.4% and infectious uveitis in 18.7%. 49.4% of subjects suffering from anterior uveitis tested positively for the HLA-B27 antigen. In posterior uveitis cases 29% were caused by ocular toxoplasmosis and 17.7% by multifocal choroiditis. Conclusion Ophthalmologists, rheumatologists, infectiologists, neurologists and general practitioners should be familiar with the differential diagnosis of uveitis. A better interdisciplinary approach could help in tailoring of the work-up, earlier diagnosis of co-existing diseases and management of uveitis patients.

Abatacept (ABA), a selective T cell costimulation modulator that binds to CD80 and CD86 on antigen-presenting cells, was investigated for its antiinflammatory effect in treating severe chronic uveitis associated with juvenile idiopathic arthritis (JIA). Our retrospective study was conducted by members of the Multinational Interdisciplinary Working Group for Uveitis in Childhood (MIWGUC). Patients with JIA who are receiving ABA treatment for active uveitis were included. In all patients, uveitis had been refractory to previous topical and systemic corticosteroids, immunosuppressives, and at least 1 tumor necrosis factor-α inhibitor. A standardized protocol was used to document uveitis (MIWGUC) and arthritis. Baseline visit and visits at 3, 6, 9, and 12 months before and after ABA start were evaluated. Primary outcome measure was defined as achievement of uveitis inactivity; secondary outcome measures were tapering of corticosteroid and/or immunosuppressive treatment, and occurrence of complications. In all, 21 patients (16 female) with active uveitis (n = 21) and arthritis (n = 18) were included (mean age 11.8 ± 3.6 yrs). In 7 of 18 patients with active arthritis at baseline, inactivity was achieved following ABA treatment. Uveitis inactivity was achieved in 11 patients, but recurred later in 8 of them, and remained active in another 10 cases. Systemic corticosteroids or immunosuppression were tapered in 3 patients, but uveitis recurred in all of them during further followup. Ocular complications secondary to uveitis were present in 17 patients at baseline, while 3 patients developed new ocular complications during followup. A sustained response to ABA was uncommon in patients with severe and refractory uveitis.

To report the anatomical pattern and etiological spectrum of uveitis in an urban multi-ethnic population from Barcelona, Spain. General and specific epidemiological data for the most prevalent aetiologies are also calculated. A cross-sectional study of consecutive uveitis cases was performed between 1 January 2009 and 31 December 2012. Exogenous endophthalmitis, surgery-related, post-traumatic and toxic uveitis along with masquerade syndromes were excluded. Anatomical (Standard Uveitis Nomenclature criteria) and aetiological patterns (by tailored tests), age, sex, geographical origin and laterality were analysed. Mean incidence and prevalence were calculated for a mid-period reference population. From 1022 patients included, 52% were anterior uveitis (AU), 23% posterior, 15% panuveitis and 9% intermediate uveitis. Aetiologically, 26% were unclassifiable, 29% infectious, 25% associated with systemic immune diseases, and 20% corresponded to ocular-specific syndromes. Among classified causes, herpesvirus (12%), toxoplasma (7%), Behçet's disease (BD) (5%), HLA-B27-isolated AU (5%), ankylosing spondylitis (5%), tuberculosis-related uveitis (TRU) (5%), birdshot chorioretinopathy (3%) and sarcoidosis (3%) were the most frequent. Non-Spanish origin was recorded in 22%, with 47% of Vogt-Koyanagi-Harada and 36% of toxoplasma cases coming from South America, 10% of BD and 11% of TRU from Africa and 24% of TRU cases from Asia. A mean annual incidence of 51.91 cases/100,000 inhabitants was found for the referral population. In our referral area, 74% of the uveitis cases can be correctly classified. A large myriad of uveitis aetiologies with a strong geographical origin burden are found in Western urban multi-ethnic populations. © 2015 Acta Ophthalmologica Scandinavica Foundation.

To assess the efficacy and tolerability of mycophenolate sodium (MPS) in the therapy of children with chronic non-infectious uveitis. Retrospective analysis of 23 children with chronic uveitis, treated with MPS, with a follow-up of at least 6 months. The main outcome measures were time to uveitis reactivation and corticosteroid-sparing effect under MPS treatment. The secondary outcome measures were best-corrected visual acuity (BCVA) and treatment-related side effects. From 23 patients included in the study, 2 patients had anterior uveitis, 19 had intermediate uveitis and 2 had panuveitis. The probability of reactivation-free survival after MPS initiation was estimated as 65% at both 1 and 2 years. The probability of discontinuing systemic corticosteroids after 1 year of treatment was 39% and after 2 years 51%. The probability to taper corticosteroids to a daily dosage of ≤0.1 mg/kg after 1 and 2 years was 62% and 85%, respectively. BCVA improved or remained stable in 96% of eyes after 1 year of therapy. Treatment-related side effects were found in nine children (rate: 0.17/patient-year). No therapy discontinuation because of side effects was needed. Our data suggest that MPS is useful and well tolerated in children with chronic uveitis. MPS seems to be an effective drug for the treatment of chronic non-infectious uveitis of childhood and may be preferred as a first-line steroid-sparing agent in this form of uveitis.

Anterior uveitis is the most common form of intraocular inflammation. The main aim of this study was to determine the viral etiology in patients with unilateral cases of anterior uveitis. A total of 12 consecutive patients with the diagnosis of idiopathic unilateral anterior uveitis were included prospectively. Aqueous specimens were obtained from each patient by anterior chamber paracentesis and subjected to the detection of viral DNA/RNA genome by polymerase chain reaction assay for herpes simplex virus, varicella zoster virus, cytomegalovirus, Epstein-Barr virus, and rubella virus. There were six male and six female patients. The mean age was 43 years, with an age range of 11-82 years. All 12 cases presented with unilateral anterior uveitis. In four (33%) patients, polymerase chain reaction was positive for viral genome. Two patients were positive for herpes simplex virus type 1, one patient was positive for cytomegalovirus and one for Epstein-Barr virus. Recent molecular diagnostic assays would help in the identification of the causative agent in patients with unilateral anterior uveitis.

To determine factors associated with the diagnosis of tuberculous uveitis and the response to anti-tuberculous treatment (ATT). A retrospective case study was performed at the University Medical Centre Utrecht between October 2007 and December 2009. Patients with possible tuberculous uveitis (TBU) were selected from all patients with an unexplained uveitis. Demographics, ethnicity, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), tuberculin skin test (TST), QuantiFERON (QFT) test, and ocular findings were evaluated. An interdisciplinary panel discussed if there was a presumed TBU and decided to start treatment. When there was a decrease in intraocular cell count and/or improvement in visual acuity after ATT, the confirmation of presumed TBU was made. Of 585 patients with unexplained uveitis, 66 (11.3%) fulfilled the definition of possible TBU. Ten (15.4%) patients were regarded as having presumed TBU and received ATT. All of them had latent tuberculosis (LTB). The ocular situation improved in seven patients (70%). A history of TB contact, abnormalities on chest radiology, and extraocular manifestations of TB were associated with a good response to ATT in the case of presumed tuberculous uveitis. Tuberculous uveitis remains difficult to diagnose. No clearly correlating factors that predicted the response to ATT, including ocular parameters, could be identified.

To study the anamnestic immune response to retinal specific antigens of two patients suffering from a rare triad of retinitis pigmentosa, Coats disease and uveitis. 17-year-old girl presented with an acute episode of panuveitis, and her 19-year-old brother suffered from chronic uveitis. On examination, both patients showed retinal vascular changes and subretinal exudations typical of Coats disease, with bone-spicule pigmentary changes as observed in retinitis pigmentosa. All routine examinations were unrevealing. However, the peripheral lymphocytes from these two siblings gave a specific anamnestic response to retinal antigens in vitro. A stimulation index of 4.6 was obtained when the sister's lymphocytes were stimulated with interphotoreceptor binding protein, IRBP--during the acute stage of the uveitis. The brother's lymphocytes showed a stimulation index of 2.7 towards S-Ag during the chronic phase of his uveitic condition. These results indicate that autoimmunity towards retinal antigens may play some role in specific types of retinitis pigmentosa. Whether these autoimmune reactions are a primary pathological mechanism or are secondary to the extensive destruction of the photoreceptor layer resulting from the retinitis pigmentosa remains debatable.

This retrospective study investigated the efficacy of tocilizumab (TCZ), a fully humanized antibody that binds both to soluble and membrane bound IL-6 receptors, for the treatment of uveitis-related cystoid macular edema (CME) refractory to immunomodulatory therapy. Five refractory patients with uveitis-related CME who received TCZ between January and August 2012 were included. All patients received 8 mg/kg TCZ at 4-week intervals. Data regarding patient demographics, use of immunosuppressive drugs, biologic agents or intravitreal therapies prior to TCZ infusions were collected. Main outcome measure was central foveal thickness (CFT) measured by optical coherence tomography at 6 months. Secondary outcome measures were degree of anterior and posterior chamber inflammation (Standardization of Uveitis Nomenclature Working Group criteria) and visual acuity (logarithm of the minimum angle of resolution [log-MAR]) at month 6. Adverse events (AEs) related to TCZ therapy were also assessed. Eight eyes from five patients (all females) were included. Mean age was 49.4 years (range, 30-68). Mean follow-up was 8.4 months (range, 6-12). Before TCZ, all patients received and failed conventional immunosuppressive therapy and had received at least another biologic agent. Uveitis diagnoses were Birdshot chorioretinopathy (n = 3), juvenile idiopathic arthritis (JIA)-associated uveitis (n = 1), and idiopathic panuveitis (n = 1). Mean evolution of CME was 13.4 years (range, 2-30). Mean baseline CFT (95% confidence interval) was 602 ± 236 μm at baseline, 386 ± 113 μm at month 1 (p = 0.006), 323 ± 103 μm at month 3 (p = 0.026), and 294.5 ± 94.5 μm at month 6 (p = 0.014). Median best-corrected visual acuity (BCVA) improved from 0.66 ± 0.57 at baseline to 0.47 ± 0.62 at month 6 (p = 0.035). After 6 months, an improvement of ≥ 2 lines of BCVA was observed in 50% of eyes (p = 0.028) remained stable in 25% and worsened in none of the patients. Sustained uveitis remission was

Uveitis associated with juvenile idiopathic arthritis (JIA-associated uveitis) is a vision-threatening disorder with a high complication rate. Besides early diagnosis within screening programs an adequate therapy is essential for improvement of the long-term prognosis. Corticosteroid therapy is often insufficient. In addition to conventional immunosuppression, immunomodulatory drugs, so-called biologicals, are novel highly effective treatment modalities. A systematic search of the literature was carried out for biologicals currently used in the treatment of JIA-associated uveitis. Review of current publications, summary of treatment guidelines and discussion of treatment options for therapy refractive patients. In accordance with the current recommendations tumor necrosis factor (TNF) inhibitors are administered if uveitis inactivity cannot be achieved with topical corticosteroids and in the next stage with immunosuppressants (methotrexate preferred). According to the currently available data adalimumab is then preferred. When the effectiveness of TNF inhibitors ceases during long-term administration and/or recurrences, other biological response modifiers are attractive treatment options (e. g. lymphocyte inhibitors or specific receptor antagonists). The TNF inhibitors are of major importance for the treatment of JIA-associated uveitis. Prospective studies and registries would be desirable in order to be able to compare the value of TNF inhibitors and other biologicals and for optimization of treatment recommendations.

Aim The aim of this study is to characterise the choroidal features of patients diagnosed with sarcoid- and tuberculosis (TB)-associated granulomatous uveitis using spectral domain optical coherence tomography (OCT). Methods Twenty-seven patients (27 eyes) diagnosed with sarcoid- (13 eyes) and TB (14 eyes)-related uveitis were included in this retrospective, cross-sectional study. Over a six-month period, patients diagnosed with sarcoid and TB granulomatous uveitis were scanned using enhanced depth imaging OCT. Clinical and demographical characteristics were recorded, including the method of diagnosis, disease activity, site of inflammation (anterior or posterior), treatments, and visual acuity (VA). Manual segmentation of the choroidal layers was performed using custom image analysis software. Results The main outcome measure was OCT-derived thickness measurements of the choroid and choroidal sublayers (Haller's large vessel and Sattler's medium vessel layers) at the macula region. The ratio of Haller's large vessel to Sattler's medium vessel layer was significantly different at the total macula circle in eyes diagnosed with TB uveitis (1.47 (=140.71/95.72 μm)) compared with sarcoid uveitis (1.07 (=137.70/128.69 μm)) (P=0.001). A thinner choroid was observed in eyes with a VA ≥0.3 LogMAR (Snellen 6/12; 198.1 μm (interquartile range (IQR)=147.0–253.4 μm) compared with those with VA uveitis, and choroidal thickening may be a feature of active granulomatous uveitis.

UVEITIS INA RHEUMATOLOGISTS PRACTICE: A ROLE OF TUMOR NECROSIS FACTOR-а INHIBITORS

Directory of Open Access Journals (Sweden)

Sergey Valentinovich Moiseyev

2009-01-01

Full Text Available Uveitis frequently develops in patients with ankylosing spondylitis (AS and other autoimmune diseases. It is occasionally characterized by a severe recurrent course and untreatable with systemic glucocorticoids (GC and standard immunosuppressive agents. The results of (mainly small clinical trials, as well as some observations suggest that therapy with tumor necrosis factor-а (TNF-а inhibitors is effective in such patients. There is the strongest evidence that they are beneficial in treating recurrent uveitis in patients with AS, infliximab having some efficacy advantages over etanercept and adalimumab. Accordingly, chronic uveitis in AS can be considered as an additional argument in favor of the use of TNF-а inhibitors. Furthermore, treatment with drugs of this group is warranted in severe uveitis refractory to GC and immunosuppressants. It is conceivable that in some forms of uveitis, for example, in patients with Behcet's disease, treatment with TNF-а inhibitors should be initiated at an earlier stage as the efficacy of standard immunosuppressants is generally limited

Current understanding of the role of oxidative stress in ocular inflammatory diseases indicates that antioxidant therapy may be important to optimize the treatment. Recently investigated antioxidant therapies for ocular inflammatory diseases include various vitamins, plant products and reactive oxygen species scavengers. Oxidative stress plays a causative role in both non-infectious and infectious uveitis complications, and novel strategies to diminish tissue damage and dysfunction with antioxidant therapy may ameliorate visual complications. Preclinical studies with experimental animals and cell culture demonstrate significance of anti-inflammatory effects of a number of promising antioxidant agents. Many of these antioxidants are under clinical trial for various inflammatory diseases other than uveitis such as cardiovascular, rheumatoid arthritis and cancer. Well planned interventional clinical studies of the ocular inflammation will be necessary to sufficiently investigate the potential medical benefits of antioxidant therapies for uveitis. This review summarizes the recent investigation of novel antioxidant agents for ocular inflammation, with selected studies focused on uveitis. PMID:21182473

To evaluate retrospectively the long-term efficacy of rituximab in patients with severe juvenile idiopathic arthritis (JIA)-associated uveitis. Eight patients (15 eyes) with severe and longstanding JIA uveitis, who had an inadequate response in controlling uveitis to one or more biologic agents including tumour necrosis factor blockers and abatacept, received rituximab therapy. Rituximab was given at a dose of 1000 mg per infusion on days 1 and 15 and then every 6 months. Clinical responses to treatment, including decrease in uveitis activity, visual acuity changes, reduction of concomitant local and systemic corticosteroid and/or immunosuppressants, and occurrence of adverse events, were assessed. Eight patients with a mean±SD age of 22.8±5.5 years were treated. The mean ocular disease duration was 17.7 years; the mean±SD follow-up time on rituximab was 44.75±4.9 months; and the mean number of rituximab infusions received was 8.75 (range 6-12). All patients achieved complete control of uveitis, but in two patients rituximab was discontinued due to inefficacy in treating arthritis. The decrease in uveitis activity was evident 4-5 months after the first infusion. Systemic corticosteroids and immunosuppressants used in association with rituximab were discontinued in five patients at the end of follow-up. None of the patients experienced visual worsening during the follow-up. No drug-related complications were encountered. Rituximab may be a promising effective treatment option for refractory uveitis associated with JIA leading to long-term quiescence of uveitis, particularly for patients who have not previously responded to other biologic therapies.

The Future is Now – Biologics for Non-Infectious Pediatric Anterior Uveitis

Science.gov (United States)

Lerman, Melissa A.; Rabinovich, C. Egla

2015-01-01

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 reduce 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. PMID:25893479

To report the primary endpoint analyses of the safety and efficacy of 2 different doses of intravenous (IV) infusions of tocilizumab (TCZ), an IL-6 inhibitor, in eyes with noninfectious intermediate uveitis, posterior uveitis, or panuveitis. Randomized, controlled, multicenter clinical trial. STOP-Uveitis is a randomized, open-label safety, efficacy, and bioactivity clinical trial conducted at 5 clinical centers across the United States. The study evaluated the role of TCZ in patients with noninfectious uveitis (NIU). Thirty-seven patients with NIU were randomized into one of 2 treatment groups in a ratio of 1:1. Group 1 received IV infusions of 4 mg/kg TCZ and group 2 received IV infusions of 8 mg/kg TCZ. Infusions were given every 4 weeks in both groups until month 6 (primary endpoint). Primary outcome measure was incidence and severity of systemic and ocular adverse events through month 6. Secondary outcome measures included mean change in visual acuity (VA), vitreous haze (VH), and central macular thickness (CMT) at month 6. A total of 37 patients were randomized in the study. At month 6, 43.5% of patients who had the potential for a 2-step decrease in VH demonstrated a 2-step decrease (40% in Group 1 and 46.1% in Group 2). Mean change in CMT was -83.88 ± 136.1 μm at month 6 (-131.5 ± 41.56 μm in Group 1 and -38.92 ± 13.7 μm in Group 2). Mean change in VA was +8.22 ± 11.83 ETDRS letters at month 6 (10.9 ± 14.6 in Group 1 and 5.5 ± 7.8 in Group 2). Repeated infusions of TCZ were well tolerated. Repeated IV administrations of TCZ are well tolerated. TCZ (both 4 and 8 mg/kg) is effective in improving VA and reducing VH and CMT in eyes with noninfectious intermediate uveitis, posterior uveitis, and panuveitis. Copyright © 2017 Elsevier Inc.

The role of uveitis, an uncommon ocular disease, is often neglected in research and treatment of autoimmune conditions. The study described the spectrum of uveitis at a referral center in North Italy, and compared that to a previously published series of patients. We reviewed all patients with uveitis diagnosed from 2013 to 2015 at the Immunology Eye Unit, Arcispedale S. M. Nuova-IRCCS, Reggio Emilia, Italy. We examined patient characteristics, disease spectrum, and etiologies. In total, 990 cases of uveitis were identified, who were mostly female (59%) with a median age at presentation of 44 years (interquartile range = 29-57). Anterior uveitis was most frequent (53.5%), followed by panuveitis (22.8%), posterior (16.2%), and intermediate uveitis (5.5%). Anterior herpetic uveitis (15.6%), Fuchs uveitis (9.7%), and HLA-B27 positive anterior uveitis (7.7%) were the most common specific diagnoses. Compared with the previous series, we observed an increased incidence of uveitis, and a different pattern of diagnoses. Rates of herpetic, HLA-B27 positive uveitis, and presumed ocular tuberculosis were higher, but Fuchs uveitis was less frequent. The pattern of uveitis appears to be changing, very likely due to population-level increases in infectious diseases, to the availability of new diagnostic tests and to the interdisciplinary approach used in patient diagnosis.

Inflammation generates changes in the protein constituents of the aqueous humor. Proteins that change in multiple models of uveitis may be good biomarkers of disease or targets for therapeutic intervention. The present study was conducted to identify differentially-expressed proteins in the inflamed aqueous humor. Two models of uveitis were induced in Lewis rats: experimental autoimmune uveitis (EAU) and primed mycobacterial uveitis (PMU). Differential gel electrophoresis was used to compare naïve and inflamed aqueous humor. Differentially-expressed proteins were separated by using 2-D gel electrophoresis and excised for identification with matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF). Expression of select proteins was verified by Western blot analysis in both the aqueous and vitreous. The inflamed aqueous from both models demonstrated an increase in total protein concentration when compared to naïve aqueous. Calprotectin, a heterodimer of S100A8 and S100A9, was increased in the aqueous in both PMU and EAU. In the vitreous, S100A8 and S100A9 were preferentially elevated in PMU. Apolipoprotein E was elevated in the aqueous of both uveitis models but was preferentially elevated in EAU. Beta-B2-crystallin levels decreased in the aqueous and vitreous of EAU but not PMU. The proinflammatory molecules S100A8 and S100A9 were elevated in both models of uveitis but may play a more significant role in PMU than EAU. The neuroprotective protein β-B2-crystallin was found to decline in EAU. Therapies to modulate these proteins in vivo may be good targets in the treatment of ocular inflammation.

Full Text Available Inflammation involving the uveal tract of the eye, termed uveitis, is frequently associated with various rheumatic disease, including seronegative spondylarthropathies, juvenile rheumatoid arthritis, Crohn’s disease and Behçet’s disease. Scleritis and keratitis may be associated with rheumatoid arthritis and systemic vasculitides such as Wegener’s granulomatosis. Immune-mediated uveitis can have a chronic relapsing course and produce numerous possible complications, many of which can result in permanent vision loss. Treatment typically includes topical or systemic corticosteroids with cycloplegic-mydriatic drugs and/or noncorticosteroid immunosuppressants, but often there is an insufficient clinical effectiveness. Anti-TNFα therapy is promising in the treatment of sight threatening uveitis, particularly in patients with Behçet’s disease. However, there have been also reports of new-onset uveitis during treatment of joint disease with TNFα inhibitors. We describe a case of new-onset uveitis in a patient with rheumatoid arthritis during therapy with etanercept at first and infliximab at last. Although we cannot exclude uveitis as linked to rheumatoid arthritis, it is unlike that the uveitis arises when the joint disease is well controlled. The hypothetical paradoxical effect of anti-TNF is here discussed.

Late in-the-bag intraocular lens (IOL) dislocation is an unusual complication of cataract surgery, being strongly associated with pseudoexfoliation, less so with previous vitreoretinal surgery, myopia and uveitis. We present the clinical features, management and outcomes of late spontaneous IOL dislocation in a series of patients with uveitis. A retrospective case series of IOL dislocation affecting patients in the Manchester Uveitis Clinic, UK. The uveitis diagnosis, IOL type, presentation and management are discussed. Six patients from out of 1056 undergoing cataract surgery (0.57%) were affected. Uveitis was the only identified risk factor for IOL dislocation, which occurred a mean 10.3 years following uncomplicated cataract surgery by phakoemulsification with endocapsular IOL implantation. The dislocation was in-the-bag in all six cases. Two patients presented with the IOL in the anterior chamber, and required removal of the IOL-bag complex, and are using aphakic refractive correction. Two patients with inferior IOL subluxation have been managed conservatively. Two patients underwent pars plana vitrectomy with sutureless scleral fixation of the existing IOL in one case, and IOL exchange with a scleral sutured IOL in the other. IOL dislocation is an uncommon late complication in patients with uveitis. Conservative management is appropriate in patients with tolerable symptoms, or in those with difficult uveitis. Otherwise, fixation of the existing IOL, or removal and implantation of a secondary IOL, may be necessary. Angle-supported, or iris-enclaved IOLs, are not of proven safety in this patient group; scleral-fixated posterior chamber IOLs are the favoured approach in our service.

Infectious uveitis is a significant cause of blindness in South Africa, especially among HIV-infected individuals. The visual outcome of uveitis depends on early clinical and laboratory diagnosis to guide therapeutic intervention. Analyses of aqueous humor, obtained by anterior chamber paracentesis, directs the differential diagnosis in infectious uveitis. However, although safe and potentially cost-effective, diagnostic anterior chamber paracentesis is not common practice in ophthalmic care across Africa. We seek to draw attention to this important procedure that could improve the diagnosis and prognosis of infectious uveitis.

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

To report the trends in etiology of patients with anterior uveitis (AU) in Singapore over 6 years. A retrospective review of the clinical records of all new patients who presented with anterior uveitis to the uveitis subspecialty clinic from 2005 to 2010 at Tan Tock Seng Hospital, Singapore. There were 552 new cases of AU. This comprised 59.5% of a total of 928 new patients diagnosed with uveitis from 2005 to 2010. The mean age was 48.0 ± 17.2 years. There was a male predominance (62.5%), with a male:female ratio of 1.7:1. The majority were of Chinese ethnicity (69%), followed by Malays (13.2%). Most cases were unilateral (79.5%) and idiopathic (50.4%). Common etiological causes included Fuchs heterochromic iridocyclitis (FHI) (5.6%), ankylosing spondylitis (AS)-related AU (5.1%), herpes simplex virus (HSV) (4.7%), and herpes zoster virus (HZV) (4.5%). There were increasing trends in AS-related AU from 3.2% in 2008 to 6.5% in 2010, and psoriasis-associated AU from 1.7% in 2005 to 4.0% in 2008. There were decreasing trends in the incidence of FHI from 10.6% in 2006 to 4.7% in 2009. No change in incidence of viral etiologies was noted, but cytomegalovirus-related immune-recovery uveitis (IRU) comprised 7.4%. IRU showed an increasing trend from 1.7% in 2005 to 11.9% in 2007, then decreased to 3.3% in 2010. Using the Pearson chi-square test, there was no statistically significant association between ethnicities (Chinese, Malay, Indian) comparing infectious and noninfectious cases (p = 0.788), idiopathic and nonidiopathic cases (p = 0.170), or between the various etiologies of uveitis (p = 0.168). AU was the predominant form of uveitis seen at our centers. Infectious etiologies (18.5%) are the most common among nonidiopathic cases, with herpes viruses (9.2%) being most prevalent. Despite increased use of polymerase chain reaction (PCR) in the detection of microbial and viral DNA, there was no overall increase in detection of infectious causes for

Axial spondyloarthritis (axial SpA) is characterized by inflammation of the spine and sacroiliac joints and can also affect extraarticular sites, with the most common manifestation being uveitis. Here we report the incidence of uveitis flares in axial SpA patients from the RAPID-axSpA trial, including ankylosing spondylitis (AS) and nonradiographic (nr) axial SpA. The RAPID-axSpA (NCT01087762) trial is double-blind and placebo-controlled to week 24, dose-blind to week 48, and open-label to week 204. Patients were randomized to certolizumab pegol (CZP) or placebo. Placebo patients entering the dose-blind phase were re-randomized to CZP. Uveitis events were recorded on extraarticular manifestation or adverse event forms. Events were analyzed in patients with/without history of uveitis, and rates reported per 100 patient-years. At baseline, 38 of 218 CZP-randomized patients (17.4%) and 31 of 107 placebo-randomized patients (29.0%) had past uveitis history. During the 24-week double-blind phase, the rate of uveitis flares was lower in CZP (3.0 [95% confidence interval (95% CI) 0.6-8.8] per 100 patient-years) than in placebo (10.3 [95% CI 2.8-26.3] per 100 patient-years). All cases observed during the 24-week double-blind phase were in patients with a history of uveitis; in these patients, rates were similarly lower for CZP (17.1 [95% CI 3.5-50.1] per 100 patient-years) than placebo (38.5 [95% CI 10.5-98.5] per 100 patient-years). Rates of uveitis flares remained low up to week 96 (4.9 [95% CI 3.2-7.4] per 100 patient-years) and were similar between AS (4.4 [95% CI 2.3-7.7] per 100 patient-years) and nr-axial SpA (5.6 [95% CI 2.9-9.8] per 100 patient-years). The rate of uveitis flares was lower for axial SpA patients treated with CZP than placebo during the randomized controlled phase. Incidence of uveitis flares remained low to week 96 and was comparable to rates reported for AS patients receiving other anti-tumor necrosis factor antibodies. © 2016, American College

This study seeks to evaluate the clinical characteristics of spondyloarthritis (SpA)-related uveitis in a cohort from South China and to assess the efficacy and safety of therapies based on TNF blockers. SpA patients with uveitis admitted to a south China hospital were enrolled. Demographic information, clinical characteristics, laboratory findings, intraocular inflammation, visual acuity, macular thickness, and treatments were documented. Of the 1,036 SpA patients reviewed, 182 had uveitis. Ankylosing spondylitis (AS) was the most common subtype. Unilateral uveitis was found in 51 cases (51/182, 28.0%), and unilateral alternating uveitis was found in 75 cases (75/182, 41.2%). Half of the cases were recurrent uveitis (52.2%), and acute onset was common (76.4%). The most serious complication was vision loss (0.5%). No significant difference in disease activity was found between the SpA patients with or without uveitis. Predominant improvements were found in cases treated with all three anti-TNFs (infliximab, adalimumab, and etanercept) and anti-TNFs plus methotrexate (MTX). Monotherapy of methotrexate was not adequate for inducing remission. Monotherapy of etanercept was not as effective as adalimumab and infliximab, mainly in the prevention of recurrence. No significant difference in effectiveness was found among the three anti-TNFs if MTX was added. Etanercept plus MTX were well tolerated. Infliximab and adalimumab were associated with more tuberculosis and/or hepatitis flares. Uveitis is common in SpA patients. Severe complications may develop in prolonged and intractable cases. Treatments based on anti-TNFs had good clinical response, and better safety documentation were observed in etanercept plus MTX compared to the other two anti-TNF monoclonal antibodies plus MTX.

To analyze the factors associated with response to anti-tumor necrosis factor (anti-TNF) treatment and compare the efficacy and safety of infliximab (IFX) and adalimumab (ADA) in patients with refractory noninfectious uveitis. This was a multicenter observational study of 160 patients (39% men and 61% women; median age 31 years [interquartile range 21-42]) with uveitis that had been refractory to other therapies, who were treated with anti-TNF (IFX 5 mg/kg at weeks 0, 2, 6, and then every 5-6 weeks [n = 98] or ADA 40 mg every 2 weeks [n = 62]). Factors associated with complete response were assessed by multivariate analysis. Efficacy and safety of IFX versus ADA were compared using a propensity score approach with baseline characteristics taken into account. Subdistribution hazard ratios (SHRs) and 95% confidence intervals (95% CIs) were calculated. The main etiologies of uveitis included Behçet's disease (BD) (36%), juvenile idiopathic arthritis (22%), spondyloarthropathy (10%), and sarcoidosis (6%). The overall response rate at 6 and 12 months was 87% (26% with complete response) and 93% (28% with complete response), respectively. The median time to complete response was 2 months. In multivariate analysis, BD and occurrence of >5 uveitis flares before anti-TNF initiation were associated with complete response to anti-TNF (SHR 2.52 [95% CI 1.35-4.71], P = 0.004 and SHR 1.97 [95% CI 1.02-3.84], P = 0.045, respectively). Side effects were reported in 28% of patients, including serious adverse events in 13%. IFX and ADA did not differ significantly in terms of occurrence of complete response (SHR 0.65 [95% CI 0.25-1.71], P = 0.39), serious side effects (SHR 0.22 [95% CI 0.04-1.25], P = 0.089), or event-free survival (SHR 0.55 [95% CI 0.28-1.08], P = 0.083). Anti-TNF treatment is highly effective in refractory inflammatory uveitis. BD is associated with increased odds of response. IFX and ADA appear to be equivalent in terms of efficacy. �

Uveitis is a common cause of preventable blindness although it is consider a sight-threatening condition particularly in cases with posterior segment inflammation. To deal with emergency conditions in uveitis, we must aware of the essential signs and symptoms that reflect a true uveitic emergency. Failure to recognize these essential signs and symptoms of a true uveitic emergency may result in a devastating visual outcome. This review provides general ophthalmologists and residents, clinical guidelines for the main uveitic entities that require immediate recognition and urgent intervention in the emergency room to prevent severe permanent visual loss.

Inflammatory conditions such as autoimmune uveitis often occur in women of childbearing age. During pregnancy, women may experience exacerbations of their disease in the first trimester. In the later stages of pregnancy, however, the uveitis tends to remain less active. The management of uveitis during pregnancy is a challenging task, forcing the physician to re-evaluate the patient's current therapy and offer alternative options that pose the least risk to the patient and fetus. This article will review treatments widely used for uveitis, including corticosteroid therapy, anti-metabolites, calcineurin inhibitors, and biologic therapy. It will evaluate the use of these medications in pregnancy and the postpartum state.

2014-04-01

To report our experience using Ozurdex (Allergan, Irvine, CA), a biodegradable intravitreal implant containing of 0.7 mg of dexamethasone approved for use in adults with noninfectious uveitis in adults, in the treatment of pediatric uveitis. The medical records of consecutive patients with noninfectious posterior uveitis who were unresponsive to standard treatment and subsequently received the Ozurdex implant from March 2011 to March 2013 were retrospectively reviewed. A total of 14 eyes of 11 patients (mean age, 10.1 years; range 4-12) received 22 Ozurdex implants during the study period. Of the 11 patients, 7 had idiopathic intermediate or posterior uveitis, 1 had sympathetic ophthalmia, 2 had juvenile idiopathic arthritis, and 1 had sarcoidosis. All patients were uncontrolled with standard treatment, including topical or sub-Tenon's or systemic corticosteriods and/or immune-modulation. Visual acuity improved after Ozurdex implant in 5 of 8 patients (63%). Intraocular inflammation was controlled or improved after 17 of 22 of implants (12 eyes [77%]). The frequency of topical corticosteroids was decreased and/or discontinued after 18 of 22 implants (12 eyes [82%]). Complications included implant migration into the anterior chamber (4 aphakic eyes), increased intraocular pressure (5 eyes), and progression of a preexisting cataract (1 eye). The uveitis reoccurred in 57% of eyes at 4.3 months (2-7 months) after injection. The Ozurdex implant in combination with systemic immunomodulatory therapy resulted in improved visual acuity, control of intraocular inflammation, and a decrease in corticosteroid use. In the majority of eyes the uveitis reoccurred around 4 months after injection. The adverse events in our study are similar to those identified in adult studies.

Jabs, Douglas A; Nussenblatt, Robert B; Rosenbaum, James T

2005-09-01

To begin a process of standardizing the methods for reporting clinical data in the field of uveitis. Consensus workshop. Members of an international working group were surveyed about diagnostic terminology, inflammation grading schema, and outcome measures, and the results used to develop a series of proposals to better standardize the use of these entities. Small groups employed nominal group techniques to achieve consensus on several of these issues. The group affirmed that an anatomic classification of uveitis should be used as a framework for subsequent work on diagnostic criteria for specific uveitic syndromes, and that the classification of uveitis entities should be on the basis of the location of the inflammation and not on the presence of structural complications. Issues regarding the use of the terms "intermediate uveitis," "pars planitis," "panuveitis," and descriptors of the onset and course of the uveitis were addressed. The following were adopted: standardized grading schema for anterior chamber cells, anterior chamber flare, and for vitreous haze; standardized methods of recording structural complications of uveitis; standardized definitions of outcomes, including "inactive" inflammation, "improvement'; and "worsening" of the inflammation, and "corticosteroid sparing," and standardized guidelines for reporting visual acuity outcomes. A process of standardizing the approach to reporting clinical data in uveitis research has begun, and several terms have been standardized.

Full Text Available The paper presents the results of recent studies of the efficacy of golimumab (GLM in the treatment of uveitis in patients with ankylosing spondylitis (AS. The data obtained in these studies suggest that GLM is highly effective in relieving and preventing uveitis attacks. However, all the given studies have a number of disadvantages; primarily they have included a limited number of patients. Further prospective randomized clinical trials with large sample sizes are required to evaluate the efficacy and safety of GLM for the treatment of uveitis in patients with spondyloarthritis.

To evaluate the efficacy of etanercept vs placebo in preventing relapses of uveitis in patients taking methotrexate with control of uveitis and whose methotrexate dosage was being tapered. Patients with chronic or recurrent noninfectious uveitis with inflammation controlled by low-dose methotrexate were randomized to either the drug or placebo group in a double-masked manner, given a methotrexate taper schedule, and followed for 24 weeks. The main outcome measures were control of inflammation, visual acuity, and adverse reactions. Data were analyzed both as an attempt-to-treat analysis and an analysis only of those patients who completed the study. A total of 20 patients were randomized to the drug and placebo groups. Relapse of uveitis occurred in 3 of 10 patients in the treatment group and 5 of 10 patients in the control group. Two patients in the treatment group withdrew prematurely from the study due to adverse effects. There was no significant difference between the treatment and placebo groups with regard to the rate of relapse and the final visual acuity. No patient suffered from any irreversible, long-term morbidity or mortality. Etanercept has no significant efficacy over placebo in preventing relapses of uveitis in patients being tapered from methotrexate.

Conclusions and importance: Dabrafenib and pembrolizumab therapy have both previously been associated with uveitis. Here, we document a case of a woman who developed acute uveitis in response to beginning therapy with dabrafenib and then later developed acute uveitis soon after initiating pembrolizumab. To our knowledge, this is the first time this uncommon side-effect has been reported in the same patient after receiving sequential targeted agents and checkpoint inhibitors.

2017-09-01

To present retinal pigmentary changes mimicking retinitis pigmentosa (RP) as a finding of advanced uveitis. We retrospectively reviewed charts of patients without a family history of inherited retinal degenerations who presented with retinal pigment changes and signs of past or present intraocular inflammation. Comprehensive eye examination including best-corrected visual acuity, slit-lamp examination and dilated fundus examination was performed on all patients in addition to color fundus photography, optical coherence tomography, fluorescein angiography (FA), and full-field electroretinogram testing. We identified five patients with ages ranging from 33 to 66 years, who presented with RP-like retinal pigmentary changes which were eventually attributed to longstanding uveitis. The changes were bilateral in three cases and unilateral in two cases. Four of five cases presented with active inflammation, and the remaining case showed evidence of active intraocular inflammation during follow-up. This study highlights the overlapping features of advanced uveitis and RP including the extensive pigmentary changes. Careful review of possible past uveitis history, detailed examination of signs of past or present inflammation and ancillary testing, with FA often being most helpful, are required for the correct diagnosis. This is important, because intervention can prevent further damage if the cause of the pigmentary changes is destructive inflammation.

Jejunal perforation caused by abdominal angiostrongyliasis Perfuração jejunal causada por angiostrongilíase abdominal

Full Text Available The authors describe a case of abdominal angiostrongyliasis in an adult patient presenting acute abdominal pain caused by jejunal perforation. The case was unusual, as this affliction habitually involves the terminal ileum, appendix, cecum or ascending colon. The disease is caused by the nematode Angiostrongylus costaricensis, whose definitive hosts are forest rodents while snails and slugs are its intermediate hosts. Infection in humans is accidental and occurs via the ingestion of snail or slug mucoid secretions found on vegetables, or by direct contact with the mucus. Abdominal angiostrongyliasis is clinically characterized by prolonged fever, anorexia, abdominal pain in the right-lower quadrant, and peripheral blood eosinophilia. Although usually of a benign nature, its course may evolve to more complicated forms such as intestinal obstruction or perforation likely to require a surgical approach. Currently, no efficient medication for the treatment of abdominal angiostrongyliasis is known to be available. In this study, the authors provide a review on the subject, considering its etiopathogeny, clinical picture, diagnosis and treatment.Os autores descrevem caso de angiostrongilíase abdominal em doente adulto que se manifestou como abdômen agudo devido à perfuração de alça jejunal, evento raro, uma vez que esta afecção geralmente envolve o íleo terminal, apêndice, ceco ou cólon ascendente. A doença é causada pelo nematódeo Angiostrongylus costaricensis cujos hospedeiros definitivos são roedores silvestres e os hospedeiros intermediários são caracóis e caramujos. A infecção em humanos é acidental e ocorre pela ingestão de secreção mucóide destes invertebrados presentes em vegetais ou por contato direto com o muco. A angiostrongilíase abdominal é clinicamente caracterizada pela presença de febre prolongada, anorexia, dor no quadrante inferior direito do abdômen e eosinofilia periférica. Embora a doença seja de

Smith, Wendy M

2017-05-01

The history of cyclosporine and uveitis is intertwined with the development of experimental autoimmune uveitis (EAU) animal models and the understanding that T lymphocytes play a major role in the pathogenesis of uveitis. The early studies of CsA in uveitis also demonstrated the power of collaborative efforts in translational research. Dr. Robert Nussenblatt and his colleagues were the first to show that CsA can inhibit EAU. Over many years after the initial CsA experiments, Dr. Nussenblatt's group as well as others continued to study CsA under experimental conditions as well as in clinical trials with human patients. The data and observations from these studies significantly advanced our knowledge of uveitis pathophysiology and demonstrated the value of well-designed masked, controlled treatment trials in uveitis. Dr. Nussenblatt and his collaborators delved into the most significant adverse effect of CsA, renal toxicity, and helped elucidate the pathophysiology of renal injury. They explored adjunctive treatments to improve the efficacy and decrease the toxicity of CsA and also studied other members of the cyclosporine family. Among the immunosuppressives used to treat ocular inflammation, CsA was the first, and remains the only medication comprehensively studied under both experimental and clinical conditions.

To report a case of a patient who developed uveitis-glaucoma-hyphema (UGH) syndrome after an uneventful cataract surgery and to discuss risk factors, diagnostic challenges, management options, and clinical implications. Uveitis-glaucoma-hyphema syndrome is a rare but potentially serious cataract surgery complication. Clinical manifestations include increased intraocular pressure (IOP), anterior chamber inflammation, and recurrent hyphema or microhyphema. Uveitis-glaucoma-hyphema Plus syndrome also includes accompanying vitreous hemorrhage. Although classically associated with rigid anterior chamber intraocular lenses (lOLs), cases of malpositioning and subluxated posterior chamber lOLs have also been described as possible triggers. We report a case of a 70-year-old Caucasian man who developed UGH Plus syndrome after an uneventful cataract surgery with an lOL implanted in the capsular bag. During postoperative follow-up, persistent intraocular inflammation, increased IOP, hyphema, and vitreous hemorrhage were consistent with this diagnosis. Slit-lamp examination demonstrated progressive localized iris atrophy, compatible with chafing of the posterior iris by the IOL haptic as the trigger for UGH syndrome. A pars plana vitrectomy was performed and a retropupillary intraocular lens was implanted. No further complications occurred during follow-up. Given the increasing prevalence of single-piece lOLs implanted in the capsular bag, it is important to recognize UGH syndrome as a rare but potentially serious complication.

Full Text Available Introduction. Sometimes it is not easy to clinically recognize subtle differences between intraocular lymphoma and noninfectious uveitis. The most common lymphoma subtype involving the eye is B-cell lymphoma. Case report. We presented two patients aged 59 and 58 years with infiltration of the subretinal space with a large B-cell non-Hodgkin intraocular lymphoma. The patients originally had clinically masked syndrome in the form of intermediate uveitis. As it was a corticosteroid-resistant uveitis, we focused on the possible diagnosis of neoplastic causes of this syndrome. During hospitalization, the neurological symptoms emerged and multiple subretinal changes accompanied by yellowish white patches of retinal pigment epithelium with signs of vitritis, which made us suspect the intraocular lymphoma. Endocranial magnetic resonance imaging established tumorous infiltration in the region of the left hemisphere of the cerebellum. The histopathological finding confirmed the diagnosis of large B-cell non-Hodgkin lymphoma of risk moderate degree, immunoblast - centroblast cytological type. The other patient had clinical chronic uveitis accompanied by yellowish shaped white echographic changes of the retina and localized changes in the level of the subretina. The diagnosis of lymphoma was made by brain biopsy. Conclusion. Uveitis masquerade syndrome should be considered in all patients over 40 years with idiopathic steroid-resistant uveitis. Treatment begun on time can affect the course and improve the prognosis of uveitis masquerade syndrome (UMS and systemic disease.

Uveitis is a major cause of severe visual impairment throughout the world and can be initiated by various infectious and non-infectious causes. Early recognition of specific infections is important as the treatment with antimicrobial agents might stop the progression or even cure the eye disease. To determine the infectious causes of uveitis in Thailand, intraocular fluid samples of 100 HIV-negative patients and 47 HIV-positive patients with uveitis were examined using real-time PCR analysis for herpes simplex virus, varicella zoster virus, cytomegalovirus and Toxoplasma gondii. Positive PCR results were found in 33/100 (33%) HIV-negative patients and in 33/47 (70%) HIV-positive patients with uveitis. In Thailand, cytomegalovirus was identified as the most frequent cause of infectious uveitis in both HIV-negative and HIV-positive patients (49 and 91%, respectively). PCR analysis of intraocular samples in uveitis was a valuable diagnostic assay. The pattern of uveitis observed in the Far East differs from that found in the West.

To determine the intraocular levels of methotrexate in low-dose treatment of noninfectious uveitis. One day after oral administration, the methotrexate level was measured in the aqueous humor and serum of a patient with noninfectious uveitis, who underwent cataract surgery. A fluorescence polarization immunoassay was used for determination. After oral administration, methotrexate was only measurable in aqueous humor but not in serum. In uveitis, orally administered low-dose methotrexate reaches detectable levels in aqueous humor, even in the absence of detectable levels in serum. Copyright (c) 2005 S. Karger AG, Basel.

Full Text Available Embora sejam as forrageiras mais importantes para a pecuária de corte (bovinocultura de corte no Brasil, em certas épocas ou condições, Brachiaria spp. podem ser tóxicas e causar surtos de fotossensibilização hepatógena que determinam significativas perdas econômicas. Animais que se alimentam em pastos de Brachiaria spp. comumente apresentam macrófagos espumosos isolados ou agrupados, além de cristais no interior de ductos biliares. Saponinas esteroidais têm sido identificadas nestes cristais e são responsabilizadas por lesar o fígado levando ao acúmulo de filoeritrina. Por vezes, imagens negativas desses cristais podem estar presentes no citoplasma de macrófagos espumosos. A patogênese de formação e o tipo de material armazenado nas células espumosas ainda são desconhecidos. A técnica de lectino-histoquímica visa auxiliar na detecção desses macrófagos e, consequentemente, no diagnóstico, além de identificar quais os resíduos de açúcares específicos que estão presentes no citoplasma das células espumosas. Assim, este trabalho teve por objetivo identificar quais lectinas são mais indicadas na detecção de saponinas esteroidais no fígado e rim de ovinos com fotossensibilização causada por Brachiaria decumbens. Fragmentos de fígado e rim de quinze ovinos, de ambos os sexos e idade variável, oriundos de Conceição do Mato Dentro, Minas Gerais, e um ovino mantido em pastagem livre de Brachiaria spp. foram avaliados pela técnica de lectino-histoquímica. Quatorze lectinas foram utilizadas (Con-A, DBA, SBA, PNA, SJA, RCA-I, UEA-I, WGA, SWGA, GSL, PSA, PHA-L, PHA-E e LCA. Verificou-se que, no fígado de ovinos com fotossensibilização provocada pela ingestão de Brachiaria decumbens, a lectina PNA apresentou especificidade e acentuada reatividade aos macrófagos espumosos, bem como especificidade e leve reatividade aos hepatócitos; a lectina WGA teve especificidade e moderada reatividade aos macr

Update on the use of systemic biologic agents in the treatment of noninfectious uveitis

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. PMID:24600203

Systemic corticosteroids are the mainstay of therapy for noninfectious posterior uveitis; however, various systemic side effects can occur. Intravitreal medication achieves a therapeutic level in the vitreous while minimizing systemic complications and is thus used as an exciting alternative. Corticosteroids, antivascular endothelial growth factors, immunomodulators such as methotrexate and sirolimus, and nonsteroidal anti-inflammatory drugs are currently available for intravitreal therapy. This article reviews the existing literature for efficacy and safety of these various options for intravitreal drug therapy for the management of noninfectious uveitis (mainly intermediate, posterior, and panuveitis.

The aim of the paper was to analyse frequency, causes and type of uveitis at children hospitalized in Ophthalmology Clinic of Medical Academy in Wroclaw in years 2001-2006. Material from 64 (88 pairs) children's eyes was analyzed. There were 35 (54.7%) girls and 29 (45.3%) boys admitted to the Clinic with suspicion of uveitis. There were 17 (26.6%) children with uveitis anterior, 15 (23.4%) with pars planitis and 32 (50.0%) with uveitis posterior. The uveitis occurred in both eyes in 33.9%. Aetiology of uveitis was recognized at 30 (46.9%) patients, at 12 (16.6%) cases uveitis was related to systemic disease. At 22 (34.4%) ill children recognition of aetiology was not possible. The most often cause of uveitis anterior was juvenile chronic arthrosis inflammation and it occurred at 8 (47.1%) children--5 girls, and 3 boys. For the most patients 12 (80.0%), in case of pars planitis recognition of aetiology was impossible. Toxoplasmosis was the most often cause for uveitis posterior and it occurred at 14 (43.8%) children. Parasitic background is still considerable cause of uveitis among children. Juvenile chronic arthritis is the most often cause for uveitis anterior. In considerable amount of children cases, recognition of aetiology of uveitis was not possible.

To describe the clinical course of uveitis-associated inflammatory papillitis and evaluate the utility and reproducibility of optic nerve spectral domain optical coherence tomography (SD-OCT). Data on 22 eyes of 14 patients with uveitis-related papillitis and optic nerve imaging were reviewed. SD-OCT measure reproducibility was determined and parameters were compared in active vs. inactive uveitis. Papillitis resolution lagged behind uveitis resolution in three patients. For SD-OCT measures, the intraclass correlation coefficients were 99.1-100% and 86.9-100% for intraobserver and interobserver reproducibility, respectively. All SD-OCT optic nerve measures except inferior and nasal peripapillary retinal thicknesses were significantly higher in active vs. inactive uveitis after correction for multiple hypotheses testing. Mean optic nerve central thickness decreased from 545.1 to 362.9 µm (p = 0.01). Resolution of inflammatory papillitis can lag behind resolution of uveitis. SD-OCT assessment of papillitis is reproducible and correlates with presence vs. resolution of uveitis.

Full Text Available Maize Bushy Stunt and Corn Stunt are diseases of corn caused respectively by a phytoplasma (maize bushy stunt phytoplasma and by Spiroplasma kunkelii. Both agents are restricted to the floem vessels of diseased plants. The leafhopper Dalbulus maidis is the vector of the diseases. The diseases are very harmfull to corn crops and can cause severe losses. Their importance increased very much in the last years mainly due to the continuous crops, which allow the perpetuation of corn, pathogens and vector over the year. Diseased plants show shortening, redening or yellowing and excessive proliferation of ears, among others symptoms. However, symptoms are variable according to the causal agent, environmental conditions and corn genotype. Correct diagnosis of the diseases has been reached with ELISA (“enzyme-linked immunosorbent assay” and PCR (“polymerase chain reaction”. The use of resistant genotypes of corn is the main strategy of control of the diseases.Os enfezamentos vermelho e pálido são doenças do milho causadas, respectivamente, por um fitoplasma (“maize bushy stunt phytoplasma” e pelo Spiroplasma kunkelii, organismos restritos ao floema das plantas infectadas. Ambas são transmitidas pela cigarrinha Dalbulus maidis. São doenças bastante destrutivas, podendo causar sérios prejuízos aos agricultores. A importância dessas doenças aumentou muito nos últimos anos, devido principalmente aos cultivos “safrinha”, que perpetuam o milho, os patógenos e o vetor no campo durante o ano todo. As plantas doentes exibem redução de crescimento, avermelhamento ou amarelecimento, proliferação excessiva de espigas pequenas e improdutivas, além de outros sintomas. No entanto, esses sintomas dependem do agente causal, condições climáticas e genótipo do milho. A diagnose correta tem sido feita por testes de ELISA (“enzyme-linked immunosorbent assay” e por PCR (“polymerase chain reaction”, devido à complexidade da

Uveitis can be a local eye disease or a manifestation of systemic rheumatologic disorders. However, the differences of clinical manifestations between uveitis patients with or without systemic rheumatologic disease have been seldom described in literature. We investigated the clinical features and complications of rheumatic disease-related uveitis, and compared the characteristics in patients with and without rheumatic disease in a Chinese population in Taiwan. A retrospective review was performed for all patients who had been diagnosed with uveitis between January 2009 and June 2014 at the Department of Ophthalmology, Chang Gung Memorial Hospital, Taoyuan, Taiwan. A total of 823 uveitis patients were enrolled in the study, including 123 patients with rheumatic diseases. The most frequent rheumatic diseases included ankylosing spondylitis (5.8%), followed by Behçet's disease (2.8%), sarcoidosis (1.4%), psoriasis (1.1%), and juvenile idiopathic arthritis (1.1%). Compared with patients without rheumatic disease, those with rheumatic disease-related uveitis had a lower mean age at onset (35.1 ± 15.8 years vs. 44.0 ± 17.5 years), a longer follow-up period (27.1 ± 25.3 months vs. 22.2 ± 23.0 months), a higher incidence of anterior uveitis (69.0% vs. 46.3%), less frequent posterior uveitis (4.9% vs. 21.4%), a higher incidence of recurrence (26.8% vs. 14.1%), more frequent bilateral involvement (53.7% vs. 38.8%), and more frequent posterior synechiae (17.2% vs. 9.4%). The disease course and clinical manifestations of rheumatic disease-related uveitis were different from those unrelated. Patients with rheumatic disease-related uveitis had a higher recurrent rate and more frequent posterior synechiae than patients without rheumatic diseases. Copyright © 2015.

To investigate the therapeutic value of azathioprine as monotherapy or combined with other immunosuppressive drugs for uveitis in patients with juvenile idiopathic arthritis (JIA). A retrospective multicentre study including 41 children with JIA (28 (68.2%) female) with unilateral or bilateral (n=28) chronic anterior uveitis. Azathioprine was used to treat uveitis that was active in patients receiving topical or systemic corticosteroids, methotrexate or other immunosuppressive drugs. The primary end point was assessment of uveitis inactivity. Secondary end points comprised dose sparing of topical steroids and systemic corticosteroids, and immunosuppression. At 1 year, uveitis inactivity was achieved in 13/17 (76.5%) patients by using azathioprine as systemic monotherapy and in 5/9 (56.6%) as combination therapy. During the entire azathioprine treatment period (mean 26 months), inactivity was obtained in 16/26 patients (61.5%) with monotherapy and in 10/15 (66.7%) when combined with other immunosuppressives (p=1.0). With azathioprine, dosages of systemic immunosuppression and steroids could be reduced by ≥ 50% (n=12) or topical steroids reduced to ≤ 2 drops/eye/day in six patients. In three patients (7.3%), azathioprine was discontinued because of nausea and stomach pain. Conclusions Azathioprine may be reconsidered in the stepladder approach for the treatment of JIA-associated uveitis. The addition of azathioprine may also be beneficial for patients not responding properly to methotrexate.

Full Text Available A 65-year-old male presented with decreased vision in the left eye of 15-day duration after having undergone an uneventful cataract surgery 10 months back. He had been previously treated with systemic steroids for recurrent uveitis postoperatively on three occasions in the same eye. B-scan ultrasonography showed multiple clumplike echoes suggestive of vitreous inflammation. Aqueous tap revealed Pseudomonas aeruginosa sensitive to ciprofloxacin. The patient was treated with intravitreal ciprofloxacin and vancomycin along with systemic ciprofloxacin with good clinical response. Even a virulent organism such as P.aeruginosa can present as a chronic uveitis, which, if missed, can lead to a delay in accurate diagnosis and appropriate management.

Alkaptonuria is a rare autosomal recessive metabolic disorder that may present with multi-system involvement such as ochronotic arthropathy, renal, urethral and prostatic calculi, cardiac valvular lesions and pigmentation of the skin, sclera, cartilage and other connective tissues. An association of the disease with uveitis has never been reported. We report the first case of alkaptonuria with ochronotic arthropathy presenting with recurrent acute anterior uveitis as the initial manifestation. The possible common link with the HLA-B27 gene is discussed.

To report on experience using the anti-interleukin 6 receptor antibody tocilizumab (TCZ) to treat severe and therapy-refractory uveitis associated with juvenile idiopathic arthritis (JIA). Retrospective data were gathered from patients with JIA receiving TCZ treatment for uveitis. JIA and related uveitis data (disease onset, activity, structural complications, and topical and systemic antiinflammatory treatment) were evaluated at the start of TCZ (baseline) and every 3 months during TCZ therapy. A total of 17 patients (14 women) with active uveitis were included (mean age 15.3 ± 6.9 yrs, mean followup time 8.5 mos). In all patients, uveitis had been refractory to previous topical and systemic corticosteroids, methotrexate (MTX), and other synthetic and biological disease-modifying antirheumatic drugs, including ≥ 1 tumor necrosis factor-α (TNF-α) inhibitor. Uveitis inactivity was achieved in 10 patients after a mean of 5.7 months of TCZ treatment (in 3 of them, it recurred during followup) and persisted in the remaining 7 patients. By using TCZ, systemic corticosteroids or immunosuppressives could be spared in 7 patients. Macular edema was present in 5 patients at baseline and improved in all of them under TCZ treatment. Arthritis was active in 11 patients at the initial and in 6 at the final followup visit. TCZ appears to represent a therapeutic option for severe JIA-associated uveitis that has been refractory to MTX and TNF-α inhibitors in selected patients. The present data indicate that inflammatory macular edema responds well to TCZ in patients with JIA-associated uveitis.

Full Text Available Sirichai Pasadhika,1 James T Rosenbaum2 1Department of Ophthalmology, Southern Arizona Veterans Administration Health Care System, Tucson, AZ, USA; 2Legacy Devers Eye Institute, Portland, OR, USA 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

Importance of the Field Uveitis is a challenging disease covering both infectious and noninfectious conditions. The current treatment strategies are hampered by the paucity of randomized controlled trials (RCTs) and few trials comparing efficacy of different agents. Areas Covered in this Review This review describes the current and future treatments of uveitis. A literature search was performed in PUBMED from 1965 to 2010 on drugs treating ocular inflammation with emphasis placed on more recent, larger studies. What the Reader Will Gain Readers should gain a basic understanding of current treatment strategies beginning with corticosteroids and transitioning to steroid sparing agents. Steroid sparing agents include the antimetabolites which include methotrexate, azathioprine, and mycophenolate mofetil; the calcineurin inhibitors which include cyclosporine, tacrolimus; alkylating agents which include cyclophosphamide and chlorambucil; and biologics which include the TNF-α inhibitors infliximab, adalimumab, and etanercept; daclizumab, interferon α2a, and rituximab. Take Home Message Newer agents are typically formulated from existing drugs or developed based on new advances in immunology. Future treatment will require a better understanding of the mechanisms involved in autoimmune diseases and better delivery systems in order to provide targeted treatment with minimal side effects.

The purpose of our study is to evaluate the efficacy of an adjunctive-to-traditional treatment with Norflo tablets (curcumin-phosphatidylcholine complex; Meriva administered twice a day in recurrent anterior uveitis of different etiologies. The study group consisted of 106 patients who completed a 12-month follow-up therapeutic period. We divided the patients into three main groups of different uveitis origin: group 1 (autoimmune uveitis, group 2 (herpetic uveitis, and group 3 (different etiologies of uveitis. The primary end point of our work was the evaluation of relapses frequency in all treated patients, before and after Norflo treatment, followed by the number of relapse in the three etiological groups. Wilcoxon signed-rank test showed a P < 0.001 in all groups. The secondary end points were the evaluation of relapse severity and of the overall quality of life. The results showed that Norflo was well tolerated and could reduce eye discomfort symptoms and signs after a few weeks of treatment in more than 80% of patients. In conclusion, our study is the first to report the potential therapeutic role of curcumin and its efficacy in eye relapsing diseases, such as anterior uveitis, and points out other promising curcumin-related benefits in eye inflammatory and degenerative conditions, such as dry eye, maculopathy, glaucoma, and diabetic retinopathy.Keywords: curcumin, anterior recurrent uveitis, phosphatidylcholine-bound-curcumin (Meriva

Full Text Available Alkaptonuria is a rare autosomal recessive metabolic disorder that may present with multi-system involvement such as ochronotic arthropathy, renal, urethral and prostatic calculi, cardiac valvular lesions and pigmentation of the skin, sclera, cartilage and other connective tissues. An association of the disease with uveitis has never been reported. We report the first case of alkaptonuria with ochronotic arthropathy presenting with recurrent acute anterior uveitis as the initial manifestation. The possible common link with the HLA-B27 gene is discussed.

To determine the frequency and clinical presentation of Lyme disease in patients with uveitis and to assess the value of Borrelia burgdorferi serological testing. Retrospective study on all patients with uveitis who were referred to our tertiary hospital were serologically tested for Lyme in our laboratory between 2003 and 2016. Screening consisted of determining B. burgdorferi serum IgG and IgM by ELISA method. The patient's serology was considered as positive if the ELISA-positive result in IgM and/or IgG was confirmed by an immunoblot positive in IgM and/or IgG. Lyme-associated uveitis was diagnosed based on serological results as well as response to antibiotics and exclusion of other diagnosis. Of the 430 patients with uveitis (60% women, mean age 49 years) fulfilling inclusion criteria, 63 (14.7%) had an ELISA-positive serology, confirmed by immunoblot for 34 patients (7.9%). The diagnosis of Lyme-associated uveitis was finally retained in seven patients (1.6%). These patients reported either a previous exposure including tick bite or forest walks (n=5), symptoms suggestive of Lyme disease (n=5) and resistance to local and/or systemic steroids (n=7). Among the remaining 27 positive patients, 22 had other established aetiologies and 5 other were unclassified. The seroprevalence of B. burgdorferi among our patients with uveitis was 7.9% compared with 6 to 8.5% in the general French population which leads to a low predictive value of serological testing. Its use should be reserved for patients with unexplained uveitis, an exposure history, systemic findings suggestive of Lyme disease and steroids resistance. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Intravenous immunoglobulin (IVIg) therapy has multiple mechanisms of immunomodulatory action. We wished therefore to assess its efficacy in a spectrum of patients with refractory uveitis. Retrospective review of clinical charts was conducted to document response to IVIg treatment in consecutive patients with treatment-refractory uveitis. Main outcome measures were control of intraocular inflammation, visual acuity, progression of the disease, and complications. Four (two male) patients, with a mean age at the beginning of the treatment of 47 years (range: 39-64), were included in the study. Indication for treatment was patients with active non-infectious uveitis refractory to steroids and immunomodulatory therapy. All patients received a course of 0.5 g/kg per day of IVIg for three consecutive days, repeating this course at a mean of 11 week (range: 2-39 weeks) intervals when indicated clinically. The median duration of the IVIg therapy was 7 months (range: 3-14 months). In three patients treatment resulted in stabilisation and prevention of progression of the disease, and additionally in two patients it facilitated a decrease in prednisolone dose. Treatment failed to induce long-term remission in one patient with recurrence of macular oedema. IVIg was well tolerated with neither immediate nor longer-term adverse events observed. In three out of four cases IVIg was an effective adjunctive therapy and well tolerated for the management of treatment-refractory uveitis.

Phacoemulsification with in-the-bag intraocular lens (IOL) implantation is the standard procedure for cataract surgery. Pigment dispersion and uveitis can result when an IOL is placed in the sulcus. We report a case of a 64-year-old woman, with pigmentary glaucoma, who developed recurrent uveitis following uneventful cataract surgery and an in-the-bag hydrophobic acrylic IOL implant. Recurrent uveitis did not subside despite use of topical steroids over 3 months. Dilated examination revealed capsulophimosis with anterior dislocation of the IOL haptic. The mechanical trauma to the iris due to the displaced haptic was implicated as the cause of recurrent uveitis, which completely resolved after capsular excision and IOL repositioning. This case illustrates a rare cause of recurrent uveitis due to IOL haptic dislocation following severe capsulophimosis. 2016 BMJ Publishing Group Ltd.

RESUMEN Introducción Las infecciones del tracto urinario (ITU) son frecuentes en la comunidad. Sin embargo, la información de aislamientos resistentes en este contexto es limitada en Latinoamérica. Este estudio tiene como objetivo determinar la prevalencia y los factores de riesgo asociados con ITU de inicio en la comunidad (ITU-IC) causadas por Escherichia coli productor de betalactamasas de espectro extendido (BLEE) en Colombia. Materiales y métodos Entre agosto y diciembre de 2011 se realizó un estudio de casos y controles en 3 instituciones de salud de tercer nivel en Colombia. Se invitó a participar a todos los pacientes admitidos a urgencias con diagnóstico probable de ITU-IC, y se les pidió una muestra de orina. En los aislamien-tos de E. coli se realizaron pruebas confirmatorias para BLEE, susceptibilidad antibiótica, caracterización molecular (PCR en tiempo real para genes bla, repetitive element palindromic PCR [rep-PCR], multilocus sequence typing [MLST] y factores de virulencia por PCR). Se obtuvo información clínica y epidemiológica, y posteriormente se realizó el análisis estadístico. Resultados De los 2.124 pacientes seleccionados, 629 tuvieron un urocultivo positivo, en 431 de estos se aisló E. coli, 54 fueron positivos para BLEE y 29 correspondieron a CTX-M-15. La mayoría de los aislamientos de E. coli productor de BLEE fueron sensibles a ertapenem, fosfomicina y amikacina. La ITU complicada se asoció fuertemente con infecciones por E. coli productor de BLEE (OR = 3,89; IC 95%: 1,10–13,89; p = 0,03). E. coli productor de CTX-M-15 mostró 10 electroferotipos diferentes; de estos, el 65% correspondieron al ST131. La mayoría de estos aislamientos tuvieron 8 de los 9 factores de virulencia analizados. Discusión E. coli portador del gen blaCTX-M-15 asociado al ST131 sigue siendo frecuente en Colombia. La presencia de ITU-IC complicada aumenta el riesgo de tener E. coli productor de BLEE, lo cual debe tenerse en cuenta para ofrecer

Full Text Available 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.

Purpose To characterize the risk and risk factors for intraocular pressure (IOP) elevation in pediatric non-infectious uveitis. Design Multi-center retrospective cohort study. Participants Nine hundred sixteen children (1593 eyes) uveitis followed between January 1978 through December 2007 at five academic uveitis centers in United States. Methods Medical records review by trained, certified experts. Main outcome measures Prevalence and incidence of IOP≥21 and ≥30mmHg and incidence of a rise in IOP by ≥10mmHg. To avoid under ascertainment, outcomes were counted as present when IOP-lowering therapies were in use. Results Initially 251 (15.8%) and 46 eyes (2.9%) had IOP≥21 and ≥30mmHg, respectively. Factors associated with presenting IOP elevation included age 6–12 years (versus other pediatric ages), prior cataract surgery (adjusted odds ratio≥21mmHg [aOR21]=2.42, P=0.01), pars plana vitrectomy (adjusted odds ratio≥30mmHg[aOR30]=11.1, P=0.03), duration of uveitis ≥6 months (aORs30 up to 11.8, Puveitis. Statistically significant risk factors include IOP elevation or use of IOP-lowering treatment in the contralateral eye and local corticosteroid use – that demonstrated a dose-and route of administration-dependent relationship. In contrast, use of immunosuppressive drug therapy did not increase such risk. Pediatric eyes with non-infectious uveitis should be followed closely for IOP elevation when strong risk factors such as the use of local corticosteroids and contralateral IOP elevation are present.

To explore the characteristic autofluorescence patterns of iris depigmentation in eyes diagnosed with Fuchs' heterochromic uveitis (FHU). Near-infrared autofluorescence images and colour images of iris were taken in 21 eyes of 21 patients with FHU, 30 eyes of 15 normal subjects, 30 eyes of 15 normal age-related iris atrophy and 33 eyes of 20 patients with uveitis other than FHU. The confocal scanning laser ophthalmoscope (Heidelberg Retina Angiograph 2, HRA2) was used for melanin-related autofluorescence imaging. The indocyanine green angiography mode of HRA2 was applied for near-infrared laser imaging, and the wavelength of the excitation laser was 795 nm. Iris colour images were also taken with the slit lamp. In normal iris, moderately intense autofluorescence was noted for the pigment ruff at the pupillary border, the crests in the pupillary zone and the collarette; and there was mild autofluorescence in the ciliary zone. In eyes with age-related iris atrophy and uveitis, much less autofluorescence was seen than the healthy normal irides. In eyes with FHU, there was moderate but discontinuous autofluorescence in the pigment ruff, a petaloid pattern of autofluorescence in the pupillary zone, moderate autofluorescence in the collarette and reticular pattern of autofluorescence in the ciliary zone. Characteristic autofluorescence patterns appeared in eyes diagnosed with FHU. Near-infrared autofluorescence is a promising objective technique to document the iris changes in FHU.

Full Text Available BACKGROUND Intermediate Uveitis also known as pars planitis essentially affects the pars plana of ciliary body and periphery of choroid. It occurs particularly in young adults with female predominance. Determining the aetiology of intermediate uveitis is one of the most difficult problem in curing the patient. This is a study of presentation, progression and follow up of a group of people diagnosed as intermediate uveitis, seeking medical care in south Indian population. MATERIALS AND METHODS A prospective study was done to identify the pattern of uveitis in a uveitis clinic population of a major referral centre in South India. A total number of 25 patient and 30 eyes were followed from January 2016 to April 2017. A standard clinical protocol, laboratory investigations, were used for the final diagnosis. A standard treatment protocol was followed and patients were reviewed accordingly. RESULTS There were 13 female and 12 male patients. Mean age of presentation was 29 ± 3.6 years (with a range of 10- 47 years. Among the 25 patient 15 were bilateral rest being unilateral. Among the cases 3 presented with grade 1 vitritis, 15 with grade 2 vitritis, 5 with grade 3 vitritis and 2 with grade 4 vitritis. Snowballs were seen in inferior quadrant of 7 patients. Among the 25 cases, 10 had ocular tuberculosis, 6 had sarcoidosis, 2 had multiple sclerosis and 7 diagnosed to be pars planitis. All cases were given specific treatment according to their aetiology. In idiopathic cases periocular injection of triamcinolone was instituted. CONCLUSION Intermediate uveitis is a potentially vision threatening condition because of its chronic course and complications if appropriate therapy is not instituted. Thorough investigations to find out the underlying aetiology should be performed to institute cause specific treatment.

Uveitis is a major extraarticular quality of life-restricting manifestation of juvenile idiopathic arthritis (JIA). The aim of the study is to describe the occurrence of uveitis in JIA patients receiving tumor necrosis factor inhibitors or methotrexate (MTX). Patients' characteristics, treatment, and the reported first occurrence of uveitis as an adverse event were searched in the Biologics in Pediatric Rheumatology Registry. The rates per exposed patients, exposure time, and time until event were calculated. Uveitis was reported as an adverse event in 75 of 3,467 patients; 51 of 2,844 patients were receiving MTX, 37 of 1,700 patients were receiving etanercept, and 13 of 364 patients were receiving adalimumab. Patients with uveitis were younger (mean ± SD age 4.6 ± 4.2 versus 7.4 ± 4.5 years; P uveitis diagnosis before starting treatment more often had a uveitis event (n = 28, 8.4%; OR 8.5, P uveitis event occurred: 11 while taking MTX (3.2 per 1,000 patient-years), 2 while taking etanercept monotherapy (1.9 per 1,000 patient-years), and 3 while taking etanercept and MTX combination (0.9 per 1,000 patient-years). A new uveitis event occurred early in the disease course after a median disease duration of 1.5 years (interquartile range [IQR] 1.3-3.8) while taking etanercept and 1.8 years (IQR 1.8-2.1) for the MTX cohort. A recurrent uveitis event was reported after a disease duration of 7.6 years (IQR 4.3-10.0) in the etanercept cohort and 4.8 years (IQR 1.0-5.8) in the MTX cohort. Univariate analysis showed that MTX, but not etanercept or adalimumab, led to a lower rate of uveitis. Patients with a history of uveitis had higher risks for uveitis events while taking both etanercept and adalimumab. Methotrexate turned out to be protective. Few patients developed a first uveitis event while taking etanercept, while the rate is comparable to that with MTX. Uveitis may not be attributed to be an adverse drug reaction to etanercept. © 2015, American

Uveitis, or ocular inflammation, is a cause of severe visual impairment. Rodent models of uveitis are powerful tools used to investigate the pathological mechanisms of ocular inflammation and to study the efficacy of new therapies prior to human testing. In this paper, we report the utility of spectral-domain optical coherence tomography (SD-OCT) angiography in characterizing the inflammatory changes induced in the anterior segment of a rat model of uveitis. Acute anterior uveitis (AAU) was induced in two rats by intravitreal injection of a killed mycobacterial extract. One of them received a concurrent periocular injection of steroids to model a treatment effect. OCT imaging was performed prior to inflammation induction on day 0 (baseline), and 2 days post-injection (peak inflammation). Baseline and inflamed images were compared. OCT angiography identified swelling of the cornea, inflammatory cells in the anterior and posterior chambers, a fibrinous papillary membrane, and dilation of iris vessels in the inflamed eyes when compared to baseline images. Steroid treatment was shown to prevent the changes associated with inflammation. This is a novel application of anterior OCT imaging in animal models of uveitis, and provides a high resolution, in vivo assay for detecting and quantifying ocular inflammation and the response to new therapies.

Immunopharmacotherapy of non-infectious uveitis: where do we stand?

2014-12-01

With ever-evolving concept of personalised medicine backed up with specific biomarkers for ocular inflammatory disease, there is a sudden surge of using biologics in non-infectious recalcitrant posterior uveitis. Have we understood these biologic agents enough to embark on this long enduring journey with the patient to optimise control of intraocular inflammation? On the other hand, there is still a strong inhibition of using these novel agents in management of uveitis even at tertiary referral centres. Immunopharmacotherapy of non-infectious uveitis poses a significant conundrum for both physicians and patients as it is like a two-edged sword effective to control inflammation but at the same time potentially toxic, suspected of causing long-term adverse effects. Systemic immunosuppressive therapy is used in a substantial number of most vision-threatening ocular inflammatory diseases. There is lack of randomised control trials establishing the safety of this therapy and our current practice pattern is based on retrospective studies and personal experience in using this treatment modality. This overview will highlight on the current dilemma faced by the clinicians in opting for steroid-sparing immunosuppressive therapy.

TREATMENT APPROACH FOR JUVENILE IDIOPATHIC ARTHRITIS-RELATED UVEITIS: 2012 UPDATE

Directory of Open Access Journals (Sweden)

Francesco Zulian

2012-01-01

Full Text Available Chronic anterior uveitis is the most common extra-articular complication of juvenile idiopathic arthritis. It is more frequent in the early onset forms with a higher prevalence in the oligoarticular (40% than in other juvenile idiopathic arthritis subtypes (5–14%. The risk for severe visual impairment is still high due to the development of sight-threatening complications (synechiae, band keratopathy, cataract, glaucoma, cystoid macular oedema. Treatment is not standardized and requires a complex decision-making process, involving a close collaboration between paediatric ophthalmologist and rheumatologist. Topical therapy alone is often inadequate to control ocular inflammation and bulbar injections are too invasive to perform in children therefore immunosuppressive treatment is often advocated. Low dose methotrexate is the second-line agent mostly used although no controlled studies comparing effects of early to late methotrexate treatment have been reported. Mycophenolate mofetil is effective in controlling inflammation in methotrexate -refractory patients. Its efficacy, however, seems to be more relevant in intermediate or posterior uveitis, than in juvenile idiopathic arthritis uveitis and scleritis. Anti-TNFα agents, namely infliximab and adalimimab showed effectiveness in open-label studies but no wide controlled trials have been reported so far. Adalimimab is as effective as infliximab but has an easier way of administration and a better drug tolerance. Abatacept should be used in anti-TNF refractory patients with juvenile idiopathic arthritis uveitis.

To identify clinical predictors of relapse in childhood autoimmune chronic uveitis after stopping systemic treatment. A retrospective, multicenter, cohort study. Ninety-four children in remission, receiving no treatments and with at least a 6-month followup, were enrolled. A higher probability of maintaining remission after discontinuing treatment was shown in idiopathic compared with juvenile idiopathic arthritis uveitis (Mantel-Cox chi-square = 23.21) if inactivity had been obtained within 6 months from starting systemic treatment (Mantel-Cox chi-square = 24.17) and by antitumor necrosis factor-α treatment (Mantel-Cox chi-square = 6.43). Type of disease, time, and type of systemic therapy to achieve inactivity predict different duration of uveitis remission after treatment withdrawal.

To evaluate the risks and quality-of-life (QoL) outcomes of fluocinolone acetonide implant versus systemic therapy with corticosteroid and immunosuppression when indicated for intermediate uveitis, posterior uveitis, and panuveitis. Additional follow-up of a randomized trial cohort. Two hundred fifty-five patients with intermediate uveitis, posterior uveitis, or panuveitis, randomized to implant or systemic therapy. Randomized subjects with intermediate uveitis, posterior uveitis, or panuveitis (479 eyes) were followed up over 54 months, with 79.2% completing the 54-month visit. Local and systemic potential complications of the therapies and self-reported health utility and vision-related and generic health-related QoL were studied prospectively. Among initially phakic eyes, cataract and cataract surgery occurred significantly more often in the implant group (hazard ratio [HR], 3.0; P = 0.0001; and HR, 3.8; P < 0.0001, respectively). In the implant group, most cataract surgery occurred within the first 2 years. Intraocular pressure elevation measures occurred more frequently in the implant group (HR range, 3.7-5.6; all P < 0.0001), and glaucoma (assessed annually) also occurred more frequently (26.3% vs. 10.2% by 48 months; HR, 3.0; P = 0.0002). In contrast, potential complications of systemic therapy, including measures of hypertension, hyperlipidemia, diabetes, bone disease, and hematologic and serum chemistry indicators of immunosuppression toxicity, did not differ between groups through 54 months. Indices of QoL initially favored implant therapy by a modest margin. However, all summary measures of health utility and vision-related or generic health-related QoL were minimally and nonsignificantly different by 54 months, with the exception of the 36-item Short-Form Health Survey physical component summary score, which favored implant by a small margin at 54 months (3.17 on a scale of 100; P = 0.01, not adjusted for multiple comparisons). Mean QoL results were

Intraocular inflammation (uveitis) remains a significant burden of legal blindness. Because of its immune mediated and chronic recurrent nature, common therapy includes corticosteroids, disease-modifying anti-rheumatic drugs and more recently biologics as immune modulatory agents. The purpose of this article is to identify the role of new treatment approaches focusing on small molecules as therapeutic option in uveitis. Areas covered: A MEDLINE database search was conducted through February 2017 using the terms 'uveitis' and 'small molecule'. To provide ongoing and future perspectives in treatment options, also clinical trials as registered at ClinicalTrials.gov were included. Both, results from experimental as well as clinical research in this field were included. Since this field is rapidly evolving, a selection of promising agents had to be made. Expert opinion: Small molecules may interfere at different steps of the inflammatory cascade and appear as an interesting option in the treatment algorithm of uveitis. Because of their highly targeted molecular effects and their favorable bioavailability with the potential of topical application small molecules hold great promise. Nevertheless, a careful evaluation of these agents has to be made, since current experience is almost exclusively based on experimental uveitis models and few registered trials.

To evaluate the outcomes of patients with chronic noninfectious uveitis unresponsive to conventional antiinflammatory therapy who were treated with methotrexate. Retrospective noncomparative interventional case series. All patients with chronic noninfectious uveitis treated with methotrexate at a single institution from 1985 to 1999. Charts of patients seen on the Ocular Immunology & Uveitis Service at the Massachusetts Eye & Ear Infirmary were reviewed. Patients with chronic uveitis of noninfectious origin treated with methotrexate were included in the study. Control of inflammation, steroid-sparing effect, visual acuity, adverse reactions. A total of 160 patients met the inclusion criteria. Control of inflammation was achieved in 76.2% of patients. Steroid-sparing effect was achieved in 56% of patients. Visual acuity was maintained or improved in 90% of patients. Side effects requiring discontinuation of medication occurred in 18% of patients. Potentially serious adverse reactions occurred in only 8.1% of patients. There was neither long-term morbidity nor mortality caused by methotrexate. Methotrexate is effective in the treatment of chronic noninfectious uveitis that fails to respond to conventional steroid treatment. It is an effective steroid-sparing immunomodulator, is a safe medication, and is well tolerated.

To assess the approach of specialists to ocular tuberculosis (TB). The American Uveitis Society (AUS) Listserv was surveyed using two clinical cases and general questions. Of 196 members, 87 responded (44.4%), of whom 64 were affiliated with practices in North America, while 23 were outside of North America. The survey provided normative data on how physicians evaluate patients with uveitis as well as opinions about ocular TB. Responses varied widely on such issues as (1) the pretest probability that a patient with granulomatous panuveitis had TB uveitis (range 1-75%) or that a patient with a risk factor for TB had ocular TB (range 0-90%); (2) the optimal duration of anti-TB therapy; and (3) whether therapy should be discontinued after 2 months in nonresponders. Consensus is lacking among uveitis specialists for the diagnosis or management of ocular TB.

Full Text Available Anterior segment infiltration in acute myeloid leukemia (AML presenting as hypopyon uveitis is very rare. We report this case as an uncommon presentation in a patient on remission after bone marrow transplant for AML. In addition to the hypopyon, the patient presented with "red eye" caused by ocular surface disease due to concurrent graft-versus-host disease and glaucoma. The classical manifestations of masquerade syndrome due to AML were altered by concurrent pathologies. Media opacities further confounded the differential diagnosis. We highlight the investigations used to arrive at a definitive diagnosis. In uveitis, there is a need to maintain a high index of clinical suspicion, as early diagnosis in ocular malignancy can save sight and life.

To evaluate the efficacy of methotrexate (MTX) in preventing the recurrence of acute anterior uveitis (AAU). This prospective, open, longitudinal study included patients from June 2002 to March 2005 who had either three or more episodes of AAU in the previous year, or a recurrence of AAU within 3 months before starting the trial. We excluded uveitis of infectious origin, masquerade syndromes, and patients with contraindications to MTX. The response criteria were defined as an absence of symptoms and the presence of a normal ophthalmologic examination. The study outcome compared the number of flare-ups of uveitis over an MTX-treated for 1 year to the number of flare-ups of the same group during the previous year without MTX. A total of 571 patients with uveitis were evaluated during the period of the study, and 10 fulfilled the inclusion criteria. One patient refused the treatment, and nine completed the study. The mean number of recurrences in the pre-MTX year was 3.4 (SD: 0.52), which was significantly reduced to 0.89 (SD: 1.17) in the year of treatment (P=0.011). MTX treatment seems to reduce the number of flare-ups in patients with recurrent AAU.

To present the clinical characteristics of patients with anterior uveitis who had evidence of cytomegalovirus (CMV) infection on polymerase chain reaction PCR-based assays for viral DNA in aqueous samples. This was a retrospective observational case series of 16 patients with CMV infection on qualitative polymerase chain reaction PCR-based assays for viral DNA in aqueous samples. Case records of 16 patients were reviewed and relevant clinical information was collected using a standardized data sheet. There were 10 male and 6 female patients, with 16 eyes included. The median age at the first attack was 52 years (range 27-77 years). Thirteen patients (81.3%) presented with an initial BCVA of 20/40 or better. Eleven eyes (68.8%) had anterior chamber inflammation of 1+ cells or less. Eight eyes (50.0%) had concomitant sectoral iris atrophy, while 2 eyes were noted to have heterochromic irides. Eleven patients (68.8%) presented with an elevated intraocular pressure. Seven patients (43.8%) had clinical features that led to a presumptive diagnosis of Posner-Schlossman syndrome, while 3 patients (18.8%) were initially diagnosed with Fuchs heterochromic iridocyclitis. Six patients were initially treated for uveitic glaucoma or anterior uveitis of unknown cause. There is a spectrum of clinical manifestations of CMV anterior uveitis. A high index of suspicion of a possible viral etiology, especially CMV, and subsequent accurate identification of the virus involved are fundamental to the overall therapeutic approach.

To assess the approach of international specialists, who primarily practice in tuberculosis-endemic areas, to ocular tuberculosis (TB). International experts from India, Brazil, Taiwan, and more than 10 other countries were surveyed using two clinical cases and general questions. A total of 244 experts were sent a survey about the treatment and diagnosis of ocular tuberculosis; 65 responded (27%), of whom 34 were affiliated with practices in India, while 31 primarily practice at international sites outside of India and North America. The data from this survey were compared with the results of a similar survey sent to members of the American Uveitis Society. The survey provided normative data on how physicians evaluate patients with uveitis as well as opinions about ocular TB. Responses varied widely on topics such as tests to include in the workup of undifferentiated uveitis, initial therapy, and duration of treatment. Physicians from developing countries relied more on chest CT scans and tuberculin skin testing (TST) than their counterparts in developed countries. The approach to diagnosis and management of TB is heterogeneous worldwide. However, there are substantial differences in the clinical approach to uveitis depending on the clinician's location of practice.

To evaluate therapeutic outcomes of interferon alpha-2a (IFNα2a) treatment in patients with Behcet's disease who were refractory to immunosuppressive agents. This retrospective case series reviewed the medical records of 5 patients with refractory Behcet uveitis from January 2011 to February 2017. IFNα2a was administered at a dose of 3 million IU 3 times per week. Clinical response, relapse rate, and change of visual acuity were evaluated. The mean age of patients was 39.60 ± 9.21 years, and the median treatment duration was 6 months. Four of the 5 patients (80%) presented with responses to IFNα2a without any uveitis attack during the treatment period. The mean number of uveitis attacks/year per patient during the treatment was 0.40 ± 0.89. The mean log of the Minimum Angle of Resolution visual acuity improved from 1.44 ± 0.38 at baseline to 1.02 ± 0.58 at the final follow up. IFNα2a is an effective therapy for Behcet uveitis refractory to conventional immunosuppressants in Korean patients.

To assess the efficacy of low dose methotrexate (MTX) therapy for children with chronic anterior and intermediate uveitis. A retrospective case review of 10 children who received MTX for chronic uveitis at a tertiary referral centre was performed. The following data were recorded for each patient: age, sex, race, duration of uveitis, primary diagnosis, anatomical localisation of uveitis, corticosteroid therapy, dose range of MTX, duration of MTX therapy, and side effects of MTX therapy. Several clinical parameters were evaluated to study the effect of MTX. These included visual acuity, anterior chamber inflammation, and topical and oral corticosteroid requirement. After MTX VA of 6/6 or better was present in 100% right eyes and 80% left eyes (p = 0.055 and p = 0.016, respectively). Anterior chamber inflammation decreased in 60% of children after MTX (p = 0.0168). The requirement of topical steroid decreased from a mean of 5.6 times a day before MTX to 1.5 times a day after MTX (p = 0.005). The dose of oral steroid decreased from a mean of 18 mg per day to 2.85 mg per day (p = 0.012). The most common adverse effect was nausea (20%). No patient required discontinuation of MTX because of side effects. MTX is effective and safe for chronic anterior and intermediate uveitis in children. An increase awareness of its efficacy is required among paediatricians and ophthalmologists to prevent sight threatening complication of chronic uveitis and its treatment with long term use of steroids.

Adalimumab, a fully human anti-tumor necrosis factor α monoclonal antibody, is effective in the treatment of juvenile idiopathic arthritis (JIA). We tested the efficacy of adalimumab in the treatment of JIA-associated uveitis. In this multicenter, double-blind, randomized, placebo-controlled trial, we assessed the efficacy and safety of adalimumab in children and adolescents 2 years of age or older who had active JIA-associated uveitis. Patients who were taking a stable dose of methotrexate were randomly assigned in a 2:1 ratio to receive either adalimumab (at a dose of 20 mg or 40 mg, according to body weight) or placebo, administered subcutaneously every 2 weeks. Patients continued the trial regimen until treatment failure or until 18 months had elapsed. They were followed for up to 2 years after randomization. The primary end point was the time to treatment failure, defined according to a multicomponent intraocular inflammation score that was based on the Standardization of Uveitis Nomenclature criteria. The prespecified stopping criteria were met after the enrollment of 90 of 114 patients. We observed 16 treatment failures in 60 patients (27%) in the adalimumab group versus 18 treatment failures in 30 patients (60%) in the placebo group (hazard ratio, 0.25; 95% confidence interval [CI], 0.12 to 0.49; Ptreatment failure than placebo among children and adolescents with active JIA-associated uveitis who were taking a stable dose of methotrexate. Patients who received adalimumab had a much higher incidence of adverse events and serious adverse events than those who received placebo.

To report the long-term efficacy and safety of the interleukin-6 receptor antagonist tocilizumab for refractory uveitis-related macular edema (ME). Retrospective cohort study. Eyes with uveitis seen at a single tertiary referral center for which ME was the principal cause of reduced visual acuity. Data were obtained by standardized chart review. Central foveal thickness (CFT) measured by optical coherence tomography, degree of anterior and posterior chamber inflammation (Standardization of Uveitis Nomenclature Working Group criteria), and visual acuity (logarithm of the minimum angle of resolution [logMAR]) were recorded during tocilizumab therapy at months 1, 3, 6, and 12. Eleven eyes from 7 patients (all women) were included. Mean age was 43.4 years. Mean duration of ME was 14.2 years. Mean follow-up with tocilizumab therapy was 15.2 months (range, 12-18 months). Before tocilizumab therapy, conventional immunosuppressive therapy and 1 or more biologic agents failed in all patients. Uveitis diagnoses were birdshot chorioretinopathy (n = 3), juvenile idiopathic arthritis-associated uveitis (n = 3), and idiopathic panuveitis (n = 1). Mean CFT was 550 ± 226 μm at baseline, 389 ± 112 μm at month 1 (P = 0.007), 317 ± 88 μm at month 3 (P = 0.01), 292 ± 79 μm at month 6 (P = 0.006), and 274 ± 56 μm at month 12 of follow-up (P = 0.002). Mean logMAR best-corrected visual acuity improved from 0.67 ± 0.53 at baseline to 0.4 ± 0.56 at month 12 (P = 0.008). Tocilizumab therapy was withdrawn in 2 patients because of sustained remission at month 12. In both patients, ME relapsed 3 months after tocilizumab withdrawal. Reinitiation of tocilizumab therapy led to good uveitis control and ME resolution. Tocilizumab generally was well tolerated and no serious adverse events were reported. In this study, tocilizumab was effective in the treatment of refractory inflammatory ME. No serious adverse events were observed. Copyright © 2014 American Academy of Ophthalmology

To report the results of IFNα2a therapy in patients with Behçet uveitis refractory to azathioprine-cyclosporine combination treatment. In a retrospective study, 39 patients treated with either azathioprine-cyclosporine combination treatment (group 1, n = 23) or IFNα2a (group 2, n = 16) with a diagnosis of ocular Behçet disease (BD), were included in the study. Group 2 consisted of patients who did not respond to conventional combination therapy, and were therefore treated with IFNα2a. Clinical response and relapse rates were recorded for each group. The mean number of uveitis attacks/year per patient was 0.8 ± 1.6 in Group 1. In Group 2, a significant decrease in the mean number of uveitis attacks/year per patient was observed after initiation of IFNα2a (2.4 ± 1.8 vs 1.3 ± 2.0) (puveitis attack/year and attack-free intervals, with a partial response to both treatments. IFNα2a therapy is an effective alternative for Behçet uveitis patients where conventional combination therapy fails.

Adult-onset Still's disease is a systemic inflammatory disease which presents with uveitis and scleritis in the eye. Intravitreal dexamethasone implants are used for the treatment of refractory uveitis. A 19-year-old woman diagnosed to have adult-onset Still's disease for fevers, joint pain, and a salmon-colored bumpy rash presented with scleritis and uveitis in the left eye. Topical and systemic steroids with oral methotrexate failed to control the inflammation. We performed intravitreal injections of dexamethasone implants for side effects of steroid and refractory ocular inflammation. The therapy resulted in improvements in the patient's uveitis with reductions in scleral vessel engorgement and redness. There was no recurrence of uveitis or scleritis during 4 months following treatment. Intravitreal injections of dexamethasone implants may result in clinical improvements of refractory scleritis combined with uveitis.

Statins have been shown to reduce ocular inflammation in animal models of uveitis and to prevent development of uveitis in observational studies. There have been no experimental human studies evaluating statins' efficacy and safety in uveitis. In this study, we aimed to investigate efficacy and safety of simvastatin in patients with uveitis. For this single-center, open-label, randomized study, we enrolled patients with acute non-infectious uveitis. The patients were randomized to receive 40 mg simvastatin per day for 2 months in addition to conventional treatment or conventional treatment alone. The studied outcomes were the rate of steroid-sparing control of ocular inflammation, measures of ocular inflammation, intraocular pressure, and visual acuity. Fifty patients were enrolled in the study. Twenty-five patients were randomly assigned to receive simvastatin with conventional treatment and 25 to conventional treatment alone. Simvastatin was associated with significantly higher rates of steroid-sparing ocular inflammation control, decrease in anterior chamber inflammation, and improvement in visual acuity. The treatment was well tolerated, no serious adverse effects were observed. Our findings suggest that statins may have therapeutic potential in uveitis. These results need to be confirmed in double-blind, randomized, controlled studies.

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. 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. 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.

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.

To report the efficacy of mycophenolate mofetil (MMF) as adjunctive therapy for the treatment of multiple sclerosis (MS)-associated uveitis. In this retrospective, interventional case series, patients with MS-associated uveitis who were treated by MMF as an adjunct therapy to systemic corticosteroid were studied. Patients' demographics, clinical course, response to treatment, and complications were assessed. A total of 30 eyes of 15 patients with a mean age of 34.5 ± 8.3 years were studied. In three patients (20%), onset of uveitis preceded the diagnosis of MS. The course of MS was relapsing-remitting in 11 patients (73.3%) and secondary progressive in four patients (26.7%). At 1 year after institution of MMF, all the patients were on oral prednisolone ≤ 7.5 mg/day, all eyes were quiet without macular edema, and 53.3% of eyes gained visual improvement. Supplemental periocular and intraocular injections were needed during the first 6 months after starting MMF therapy. The systemic adverse effects were transient and minor in severity. MMF had beneficial effects on vision and intraocular inflammation with an acceptable safety profile.

Treatment of juvenile idiopathic arthritis-associated uveitis: challenges and update.

To update the current understanding of the risk factors for poor outcomes in juvenile idiopathic arthritis-related uveitis. In addition, current therapies, both traditional and biological, are reviewed. Male sex, independent of age or antinuclear antibody status, is associated with increased ocular morbidity. Having anterior chamber inflammation on first exam increases the risk of developing vision-threatening eye complications. Presence of one complication increases the risk of developing another. Risk of cataract development associated with topical glucocorticoid use is better defined. Longer duration of remission on therapy has been found to decrease the risk of disease flare after discontinuation of methotrexate. Recent studies of both nonbiological and biological therapies for arthritis-related uveitis are discussed. With a better understanding of risk factors associated with the ocular morbidity of uveitis associated with juvenile idiopathic arthritis, aggressive therapies can be targeted for improved visual outcomes. Alternative treatments to avoid long-term corticosteroid use include the use of antimetabolites and biological therapies. More prospective comparator studies and/or use of multicenter databases are needed to better understand best treatments.

Full Text Available Background: Recently, It had been recognized that oral infection, especially periodontal disease are potential contributing factors to a variety of systemic diseases, such as cardiovascular and cerebrovascular diseases, pregnancy problem, diabetes mellitus type 2, etc. However, the adverse effect of periodontal disease toward uveitis still not clearly understood especially if happens during pregnancy. Interestingly, in Indonesia, there is still a myth that pregnant women should not get any dental treatment, therefore, it may deteriorate periodontal disease during pregnancy. Purpose: to explain the possible connection between periodontal disease and uveitis and increase the awareness of these problems during pregnancy that could be understood by doctor and laymen. Reviews: literatures revealed that dental infection can caused uveitis via metastatic spread of toxin and inflammatory mediators. Additionaly, more recent investigation reported that the neural system may also stimulated by oral infection. In the orofacial regions there's trigeminal nerve complex that also related to the orbital region, thus may also involved in the uveitis pathogenesis. The effects of periodonto pathogens toxins toward immunocompetent cell and nerves had also been reported by researcher. Moreover, pregnant women are more susceptible to periodontal disease, therefore maintaining oral hygiene and dental monitoring is a mandatory. Conclusion: in woman who susceptible to uveitis, periodontal disease may exacerbate the symptoms especially in pregnancy. Therefore simple explanation about connection of oral infection-systemic diseases especially in pregnancy should be widespread among Indonesian people.

Injections of lipopolysaccharide in animal models generate acute anterior uveitis (also known as endotoxin-induced uveitis), but the effects of lipopolysaccharide injection are unknown in humans. We describe an unusual case in which acute anterior uveitis was dramatically activated subsequent to botulinum toxin injection in a patient with Behçet's disease but the acute anterior uveitis was satisfactorily attenuated by infliximab. A 53-year-old Japanese man had normal ocular findings at his regularly scheduled appointment. He had been diagnosed as having incomplete-type Behçet's disease 11 years before. Three years after the diagnosis he was given systemic infusions of 5 mg/kg infliximab every 8 weeks and he had not experienced a uveitis attack for 8 years with no treatment other than infliximab. Two days after the eye examination, he received intracutaneous botulinum toxin injections to treat axillary hyperhidrosis on both sides. Three hours after the injections, he noted rapidly increasing floaters in his right eye. Four days after the injections, his right eye showed severe acute anterior uveitis with deteriorated aqueous flare and anterior vitreous opacity. He received his scheduled infliximab injection, and the right acute anterior uveitis immediately attenuated. Botulinum toxin may have clinical effects similar to those of lipopolysaccharide in endotoxin-induced uveitis models. To the best of our knowledge, this is the first report to suggest that botulinum toxin may trigger acute anterior uveitis, although the precise mechanism is still unclear.

An Update on Treatment of Pediatric Chronic Non-Infectious Uveitis.

Sood, Arjun B; Angeles-Han, Sheila T

2017-03-01

There are no standardized treatment protocols for pediatric non-infectious uveitis. Topical corticosteroids are the typical first-line agent, although systemic corticosteroids are used in intermediate, posterior and panuveitic uveitis. Corticosteroids are not considered to be long-term therapy due to potential ocular and systemic side effects. In children with severe and/or refractory uveitis, timely management with higher dose disease-modifying antirheumatic drugs (DMARDs) and biologic agents is important. Increased doses earlier in the disease course may lead to improved disease control and better visual outcomes. In general, methotrexate is the usual first-line steroid-sparing agent and given as a subcutaneous weekly injection at >0.5 mg/kg/dose or 10-15 mg/m2 due to better bioavailability. Other DMARDs, for instance mycophenolate, azathioprine, and cyclosporine are less common treatments for pediatric uveitis. Anti-tumor necrosis factor-alpha agents, primarily infliximab and adalimumab are used as second line agents in children refractory to methotrexate, or as first-line treatment in those with severe complicated disease at presentation. Infliximab may be given at a minimum of 7.5 mg/kg/dose every 4 weeks after loading doses, up to 20 mg/kg/dose. Adalimumab may be given up to 20 or 40 mg weekly. In children who fail anti-tumor necrosis factor-alpha agents, develop anti-tumor necrosis factor-alpha antibodies, experience adverse effects, or have difficulty with tolerance, there is less data available regarding subsequent treatment. Promising results have been noted with tocilizumab infusions every 2-4 weeks, abatacept monthly infusions and rituximab.

Behçet's disease (BD) is a chronic multisystem inflammatory disorder associated to uveitis that may represent a serious sight-threatening condition. The purpose of the present study is to assess the effectiveness of adalimumab as new strategic therapeutic approach in patients affected by severe Behçet's uveitis. Clinical data from twelve selected patients (22 eyes) were retrospectively analysed. All patients received 40 mg of adalimumab subcutaneously, once every 2 weeks, in addition to traditional immunosuppressive on-going therapy and eight of them were switched to adalimumab after failure of infliximab therapy. Primary outcome measures included ocular inflammatory activity, frequency of uveitis attacks and steroid-sparing effect. Secondary outcomes were changes of best-corrected visual acuity (BCVA), impact on traditional immunosuppressive therapy and occurrence of adalimumab-related side effects. Mean age of patients (11 males and 1 female) at the onset of disease was 24.34 years (±8.62 SD). Ocular involvement resulted bilateral in 83% of cases and mainly consisted in panuveitis (68% of eyes). After mean follow-up of 21 months (±9.63 SD) all patients but one (92%) achieved uveitis remission with BCVA improvement at least in one eye. Average uveitis attacks decreased from 2 to 0,42 during adalimumab (ptreatment of patients with severe and resistant Behçet's uveitis, providing an appropriate and long-term control of ocular inflammation.

Secukinumab, a fully human anti-interleukin-17A monoclonal antibody, exhibited promising activity in a proof-of-concept study when administered in intravenous (IV) doses to patients with active, chronic, noninfectious uveitis. This study compared the efficacy and safety of different IV and subcutaneous (SC) doses of secukinumab in patients with noninfectious uveitis. Multicenter, randomized, double-masked, dose-ranging, phase 2 clinical trial. Thirty-seven patients with active noninfectious intermediate uveitis, posterior uveitis, or panuveitis who required corticosteroid-sparing immunosuppressive therapy. Patients were randomized to secukinumab 300 mg SC every 2 weeks for 4 doses, secukinumab 10 mg/kg IV every 2 weeks for 4 doses, or secukinumab 30 mg/kg IV every 4 weeks for 2 doses. Intravenous or SC saline was administered to maintain masking. Efficacy was assessed on day 57 (2-4 weeks after last dose). Percentage of patients with treatment response, defined as (1) at least a 2-grade reduction in vitreous haze score or trace or absent vitreous haze in the study eye without an increase in corticosteroid dose and without uveitis worsening or (2) reduction in corticosteroid dosages to prespecified levels without uveitis worsening. Percentage of patients with remission, defined as anterior chamber cell and vitreous haze scores of 0 or 0.5+ in both eyes without corticosteroid therapy or uveitis worsening. Secukinumab 30 mg/kg IV and 10 mg/kg IV, compared with the 300 mg SC dose, produced higher responder rates (72.7% and 61.5% vs. 33.3%, respectively) and remission rates (27.3% and 38.5% vs. 16.7%, respectively). Statistical and clinical superiority for the 30 mg/kg IV dose compared with the 300 mg SC dose was established in a Bayesian probability model. Other measures, including time to response onset, change in visual acuity, and change in vitreous haze score, showed numeric trends favoring IV dosing. Secukinumab, administered in IV or SC formulations, appeared

To evaluate treatment, ocular complications and outcomes of children with pediatric uveitis not associated with juvenile idiopathic arthritis. This was a retrospective chart review of pediatric uveitis in children under 16 years of age, recruited from the pediatric rheumatology department at Bicêtre Hospital from 2005 to 2015. Patients with juvenile idiopathic arthritis-associated and infectious uveitis were excluded. We used the Standardization of Uveitis Nomenclature Working Group to classify uveitis, disease activity, and treatment end points. We enrolled 56 patients and 102 affected eyes. The mean age at diagnosis was 10 ± 3.5 years (range 3-15), and the mean follow-up 4.2 ± 3.3 years (1-15). The main diagnoses were idiopathic (55%), Behçet disease (15%), and sarcoidosis (5%). The main localization was panuveitis in 44 of 102 eyes (43%). Corticosteroid sparing treatment was needed in 62 of 102 eyes (60%). Second-line therapies included methotrexate and azathioprine, and the third-line therapy was a biologic agent, mainly infliximab, in 33 of 102 eyes (32%). Infliximab achieved uveitis inactivity in 14 of 18 eyes (80%), in all etiologies. Severe complications were present in 68 of 102 eyes (67%). The most common were synechiae 33% of eyes, cataract (20%), and macular edema (25%). Of these, 37% were present at diagnosis. Remission was achieved in 22 of 102 eyes (21%). Conventional therapies were insufficient to treat many of the cases of posterior or panuveitis. This study underlines the need for earlier and more aggressive treatment and antitumor necrosis factor-α therapy was rapidly efficient in most cases of refractory uveitis.

There is not yet a commonly accepted, standardized approach in the treatment of juvenile idiopathic uveitis when initial steroid therapy is insufficient. We sought to assess current practice patterns within a large cohort of children with juvenile uveitis. This is a cross-sectional cohort study of patients with uveitis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRAnet) registry. Clinical information including, demographic information, presenting features, disease complications, and medications were collected. Chi-square and Fisher's exact tests were used to assess for associations between medications and clinical characteristics. Ninety-two children with idiopathic and 656 with juvenile idiopathic arthritis (JIA)-associated uveitis were identified. Indication (arthritis or uveitis) for medication use was not available for JIA patients; therefore, detailed analysis was limited to children with idiopathic uveitis. In this group, 94 % had received systemic steroids. Methotrexate (MTX) was used in 76 % of patients, with oral and subcutaneous forms given at similar rates. In multivariable analysis, non-Caucasians were more likely to be treated initially with subcutaneous MTX (P = 0.003). Of the 53 % of patients treated with a biologic DMARD, all received a tumor necrosis factor (TNF) inhibitor. TNF inhibitor use was associated with a higher frequency of cataracts (52 % vs 21 %; P = 0.001) and antinuclear antibody positivity (49 % vs 29 %; P = 0.04), although overall complication rates were not higher in these patients. Among idiopathic uveitis patients enrolled in the CARRAnet registry, MTX was the most commonly used DMARD, with subcutaneous and oral forms equally favored. Patients who received a TNF inhibitor were more likely to be ANA positive and have cataracts.

To identify the frequency and causes of uveitis leading to visual impairment in patients referred to the Low Vision Service - Department of Ophthalmology - UNIFESP, over a twenty years period. In a retrospective study, medical records of 5,461 patients were reviewed. Data from the first clinical evaluation at the Low Vision Service were collected, patient's age, gender and cause of visual impairment were analyzed. Patients with uveitis had their chart reviewed for anatomical classification and clinical diagnosis. The mean age of the patients referred to the Low Vision Service was 42.86 years and the mean age of patients with uveitis diagnosis was 25.51 years. Retinal disorders were the most common cause of visual impairment (N=2,835 patients; 51.9%) followed by uveitis (862 patients, 15.7%). Uveitis was posterior in 792 patients (91.9% of uveitis) and toxoplasmosis was the most common diagnosis (765 patients, 88.7%). In our study, uveitis represents the second cause of visual impairment in patients referred for visual rehabilitation and toxoplasmic retinochoroiditis was the most common clinical diagnosis. It affects a young working age population with a relevant social and economic impact, but the early diagnosis and treatment can improve the quality of life of these patients.

This study aimed to report the clinical outcome of children with uveitis treated with anti-tumor necrosis factor alpha (TNF-α) agents. This included a retrospective cohort study. Children with uveitis treated with infliximab or adalimumab in 2008-2014 at five dedicated uveitis clinics were identified by database search. Their medical records were reviewed for demographic data, clinical presentation, ocular complications, and visual outcome. Systemic side effects and the steroid-sparing effect of treatment were documented. The cohort included 24 patients (43 eyes) of whom 14 received infliximab and 10 received adalimumab after failing conventional immunosuppression therapy. Mean age was 9.3 ± 4.0 years. The most common diagnosis was juvenile idiopathic arthritis-related uveitis (n = 10), followed by Behçet's disease (n = 4), sarcoidosis (n = 1), and ankylosing spondylitis (n = 1); eight had idiopathic uveitis. Ocular manifestations included panuveitis in 20 eyes (46.5%), chronic anterior uveitis in 19 (44.2%), and intermediate uveitis in 4 (9.3%). The duration of biologic treatment ranged from 6 to 72 months. During the 12 months prior to biologic treatment, while on conventional immunosuppressive therapy, mean visual acuity deteriorated from 0.22 to 0.45 logMAR, with a trend of recovery to 0.25 at 3 months after initiation of biologic treatment, remaining stable thereafter. A full corticosteroid-sparing effect was demonstrated in 16 of the 19 patients (84.2%) for whom data were available. Treatment was well tolerated. Treatment of pediatric uveitis with anti-TNF-α agents may improve outcome while providing steroid-sparing effect, when conventional immunosuppression fails. The role of anti-TNF-α agents as first-line treatment should be further investigated in controlled prospective clinical trials.

Glutathione peroxidase activities and malondialdehyde levels were measured in the homogenated anterior segment of rat eyes with endotoxin induced acute anterior uveitis in euthyroid, hyperthyroid and hypothyroid rats. Malondialdehyde concentrations were found to be significantly increased (p 0.05). These results suggest that excess or deficiency of the thyroid hormones cause alterations in the malondialdehyde levels and glutathione peroxidase activities of the rat eyes in endotoxin induced uveitis, and hyperthyroidism may increase the oxidative stress in endotoxin induced acute anterior uveitis.

Introduction Uveitis, a leading cause of preventable blindness around the world, is a critically underserved disease in regard to the medications approved for use. Multiple immunomodulatory therapy (IMT) drugs are appropriate for uveitis therapy but are still off-label. These IMT agents, including antimetabolites, calcineurin inhibitors, alkylating agents, and biologic agents, have been designated as “orphan drugs” and are widely used for systemic autoimmune diseases or organ transplantation. Area covered The purpose of this paper is to comprehensively review and summarize the approved orphan drugs and biologics that are being used to treat systemic diseases and to discuss drugs that have not yet received approval as an “orphan drug for treating uveitis” by the US Food and Drug Administration (FDA). Our perspective IMT, as a steroid-sparing agent for uveitis patients, has shown promising clinical results. Refractory and recurrent uveitis requires combination IMT agents. IMT is continued for a period of 2 years while the patient is in remission before considering tapering medication. Our current goals include developing further assessments regarding the efficacy, optimal dose, and safety in efforts to achieve FDA approval for “on-label” use of current IMT agents and biologics more quickly and to facilitate insurance coverage and expand access to the products for this orphan disease.

Full Text Available Intermediate uveitis is a chronic inflammatory eye disease where the vitreous is the major site of the inflammation. It mostly affects younger patients. The inflammation can be idiopathic or related to either infectious or autoimmune systemic disease. The leading cause of visual deterioration in intermediate uveitis is cystoid macular edema and cataract is the most common complication.Criteria for treating intermediate uveitis depend on the cause of the disease. We consider the presence of cystoid macular edema, vitreous haze 2+ or more, retinal neovascularization or vasculitis. We decide to treat the patient early, because it is easier to preserve visual function and ocular structures. The basic approach to treatment is a »step approach«. We start the treatment  with periocular, intraocular or systemic corticosteroids. If the treatment is ineffective we use immunosuppressants/immunomodulators. Prognosis is improved with  early control of inflammation and early treatment of the complications.

To assess the safety and efficacy of noncorticosteroid triple immunosuppressive therapy in the treatment of refractory chronic noninfectious childhood uveitis. Subjects were retrospectively selected from a database. Patients were included if they were diagnosed with chronic, noninfectious uveitis at 16 years of age or under and treated with triple immunosuppressive therapy for at least 6 months (following failure of a combination of 2 immunosuppressants). Patient demographics, diagnoses, duration of uveitis, drug dosages, active joint inflammation, and ophthalmologic data were recorded. Efficacy outcomes for triple therapy were recorded at 6 months. Thirteen patients with bilateral uveitis were included. Using Standardized Uveitis Nomenclature (SUN) criteria, at 6 months only 11 eyes (42%) had a 2-step improvement in anterior chamber cell inflammation (n = 26). In addition, 2 patients required additional oral corticosteroid treatment. There were 4 significant infectious adverse events during a total of 21.9 patient-years (PY) on triple therapy (0.18 events per PY). In this group of children with refractory uveitis, addition of a third immunosuppressive agent did not confer substantial benefit in redressing ocular inflammation and was associated with significant infections in a minority of patients.

Full Text Available Purpose: To report a case of atypical syphilitic uveitis complicated with retinal vasculitis, proliferative retinopathy, and vitreous hemorrhage in which vitreous surgery was useful for the diagnosis and treatment. Case Report: A 38-year-old female was referred to our hospital after noticing visual disturbance in her right eye. Fundoscopy examination of that eye revealed retinal phlebitis accompanied by retinal hemorrhage and soft exudate, and remarkable exudative changes in the retinal vessels from the upper arcade to the macula region. After a blood examination, a serological test showed positive for syphilis; however, systemic findings were scarce. Syphilitic uveitis was suspected, so we administered treatment for syphilis, anticoagulant treatment for retinal vasculitis, steroids for intraocular inflammation, and photocoagulation for the retinal nonperfusion area. However, her visual acuity (VA decreased to 30 cm/counting fingers due to vitreous hemorrhage resulting from fibrovascular membrane at the optic disc. Since the vitreous hemorrhage was insufficiently absorbed, vitreous surgery was performed to remove the hemorrhage and fibrovascular tissue. Following surgery, the uveitis and retinal vasculitis subsided, and her corrected VA improved to 0.3. Postoperative examination of a fixed quantity of collected vitreous fluid for syphilis showed a Treponema pallidum hemagglutination value of 5,120 times the normal amount, thus confirming the syphilitic uveitis diagnosis. Conclusions: Our findings show that when observing patients with obstructive retinal vasculitis of unknown causes, syphilitic uveitis should be considered as a differential diagnosis, and that vitreous surgery is useful for the diagnosis and treatment of atypical syphilitic uveitis which has progressed to proliferative retinopathy.

Significant progress has been made in the treatment of noninfectious uveitis in recent years, particularly with regard to the effective use of corticosteroids and non-corticosteroid immunosuppressive drugs, including biologic agents. All of these therapeutic approaches are limited, however, by any given patient’s ability to comply with and adhere to their prescribed treatment. In fact, compliance and adherence are among the most important patient-related determinants of treatment success. We discuss strategies to optimize compliance and adherence.

Acute immunogenic uveitis was modeled in rabbits via the subcutaneous and intravitreal injections of normal horse serum. We studied the effect of instillations of 0.1% melatonin solution on the clinical course of uveitis and biochemical parameters of tear fluid and aqueous humor: antioxi-dant activity, protein concentration and α(2)-macroglobulin level. Melatonin instillations decreased clinical manifestations of uveitis. We found that the antioxidant activity in tears of the rabbits treated with melatonin was substantially higher and the α(2)-macroglobulin level lower than in untreated animals. Antioxidant activity in aqueous humor taken on day 10 of uveitis was also twice higher while protein and α(2)-macroglobulin levels were 1.5-2 times lower than in untreated animals. These data indicate that instillations of melatonin increase the local antioxidant activity and decrease the acuity of inflammation and permeability of hematoophthalmic barrier in uveitis.

To retrospectively compare the frequency and outcome of uveitis between two cohorts of patients with newly-onset juvenile idiopathic arthritis (JIA) separated by a 10 year interval. The diagnosis of JIA was made in 239 patients in 1990-1993 and in 240 patients in 2000-2003 by paediatric rheumatologists at the Rheumatism Foundation Hospital, Heinola, Finland. An ophthalmologist examined all the patients regularly and diagnosed uveitis. The demographics of the patients, type of JIA, frequency, medical treatment and outcome of uveitis were documented. The main outcome measures were the frequency and outcome of uveitis, the number of complications and the best corrected visual acuity (BCVA), need of corticosteroids and other immunosuppressive treatment. The frequency of uveitis was higher (25% vs. 18%) in the earlier cohort. The visual outcome was ≥0.5 in all JIA-uveitis patients except one in the earlier cohort. Complications were fewer (21% vs. 35%) and uveitis was milder according to the Standardisation of Uveitis Nomenclature (SUN) criteria in the later cohort. Remission of uveitis (33% vs. 42%) and arthritis (20% vs. 23%) in JIA-uveitis patients was similar in both cohorts after a follow-up of 6.6 and 5.9 years, respectively. Systemic corticosteroids were more commonly used (25% vs. 7%) in JIA-uveitis patients of the earlier cohort but the use of methotrexate was equal in both cohorts (65% vs. 67%). In this study with early and aggressive treatment and close monitoring the outcome of JIA-uveitis patients was favourable and visual loss was avoided in most cases.

Polymerase chain reaction (PCR) analysis is an important tool in the diagnosis of infectious uveitis. A retrospective, interventional study of PCR analysis of ocular fluid in suspected infectious uveitis cases between January 2014 to July 2016 was done. Nested, real-time and broad range PCR was performed for detection of the genome of Mycobacterium tuberculosis, herpes virus family, Chikungunya virus, Toxoplasma gondii, fungus, eubacterium and propionibacterium acne. Total of 100 cases included, mean age was 39.2 ± 15.4 years. Uveitis was unilateral in 82% and granulomatous in 40%. Mean visual acuity at the initial visit and final visit was 0.73 logMar and 0.63 logMar respectively. PCR analysis confirmed the clinical diagnosis in 70.1% patients. The sensitivity, specificity, positive predictive value and negative predictive value of PCR analysis was 90.2%, 93.9%, 93.9% and 90.2% respectively. The quantitative value of real-time M. tb. Positive PCR ranged from 32c/ml to 2722 c/ml. PCR assay is an accurate technique with high sensitivity and specificity to diagnose the DNA genome in infectious uveitis.

To evaluate the outcomes of treatment with mycophenolate mofetil in patients with scleritis and uveitis refractory to or intolerant of methotrexate. Retrospective noncomparative case series. Eighty-five patients with scleritis and/or uveitis who failed with or did not tolerate methotrexate and were subsequently treated with mycophenolate mofetil between 1998 and 2006. We reviewed medical records of patients who were treated with mycophenolate mofetil after methotrexate intolerance or failure at one tertiary uveitis referral practice. We recorded dose and duration of methotrexate and mycophenolate mofetil therapy, inflammation grade, Snellen visual acuity (VA), use of other immunomodulatory therapy, and adverse events. Multivariate logistic regression was used to identify factors associated with inflammation control. Control of inflammation, steroid-sparing effect, VA, and adverse effects were assessed. Inflammation was controlled with mycophenolate mofetil in 47 patients (55%), with 5 achieving durable remission off all medication. In multivariate logistic regression analysis that adjusted for gender and age, the odds of inflammation control were lower for patients with scleritis (odds ratio [OR], 0.19; 95% confidence interval [CI], 0.04-0.93; P = 0.04) than for patients without scleritis. Among patients without scleritis, the odds of inflammation control were lower for patients with juvenile idiopathic arthritis (JIA)-associated uveitis (OR, 0.14; CI, 0.02-0.81, P = 0.03) compared to patients without JIA-associated uveitis. Eight of the 11 patients (73%) who were taking concomitant prednisone were able to taper their dose to methotrexate. The odds of inflammation control were less in patients with the diagnoses of scleritis and JIA.

To evaluate whether cost, prior insurance authorization concerns, and subspecialty practice influence therapeutic decisions in the treatment of uveitis associated with juvenile idiopathic arthritis. A total of 2,965 pediatric ophthalmologists, uveitis specialists, retina specialists, and rheumatologists across the United States were surveyed via e-mail regarding their choice in long-term therapy for a hypothetical patient with uveitis associated with juvenile idiopathic arthritis. Outcomes of interest were differences in therapy choice based on cost/prior authorization and specialty practice. There were significant differences in the use of methotrexate and biologics among specialists, both with and without consideration for cost and prior authorization. Physicians in four different specialties who treat uveitis associated with juvenile idiopathic arthritis agree on methotrexate as a first-line treatment choice and a biologic immunosuppressive medication as a second choice, but there are significant differences between the specialties in their use of these medications. Cost and insurance considerations did not affect therapy selection. [J Pediatr Ophthalmol Strabismus. 2016;53(4):246-251.]. Copyright 2016, SLACK Incorporated.

Juvenile idiopathic arthritis is a relatively common chronic disease of childhood, and is associated with persistent morbidity and extra-articular complications, one of the most common being uveitis. The introduction of biologic therapies, particularly those blocking the inflammatory mediator tumor necrosis factor-α, provided a new treatment option for juvenile idiopathic arthritis patients who were refractory to standard therapy such as non-steroidal anti-inflammatory drugs, corticosteroids and/or methotrexate. The first case was a 2-year-old girl with juvenile idiopathic arthritis and uveitis who failed to respond to treatment with anti-inflammatories, low-dose corticosteroids and methotrexate, and had growth retardation. Adalimumab 24 mg/m2 every 2 weeks and prednisone 0.5 mg/kg/day were added to methotrexate therapy; steroid tapering and withdrawal started after 1 month. After 2 months the patient showed good control of articular and ocular manifestations, and she remained in remission for 1 year, receiving adalimumab and methotrexate with no side effects, and showing significant improvement in growth. Case 2 was a 9-year-old boy with an 8-year history of juvenile idiopathic arthritis and uveitis that initially responded to infliximab, but relapse occurred after 2 years off therapy. After switching to adalimumab, and adjusting doses of both adalimumab and methotrexate based on body surface area, the patient showed good response and corticosteroids were tapered and withdrawn after 6 months; the patient remained in remission taking adalimumab and methotrexate. The final case was a 5-year-old girl with juvenile idiopathic arthritis for whom adalimumab was added to methotrexate therapy after three flares of uveitis. The patient had two subsequent episodes of uveitis that responded well to local therapy, but was then free of both juvenile idiopathic arthritis and uveitis symptoms, allowing methotrexate and then adalimumab to be stopped; the patient remained in drug

The uveitis masquerade syndromes (UMS) are a group of ocular diseases that may mimic chronic intraocular inflammation. Many malignant entities such as non-Hodgkin's lymphomas may masquerade as uveitis. We report a case of an HIV-positive patient with masquerade syndrome presenting unilateral uveitis. 45-year-old Caucasian man with a diagnosis of diffuse large B-cell lymphoma (DLBCL). The patient was diagnosed by a biopsy of an abdominal mass which showed fragments of gastric mucosa with diffuse growth of neoplastic cells. At diagnosis, the patient suffered from unilateral blurring of vision and a sudden decrease of left-eye visual acuity. A slit-lamp examination of the left eye revealed a diagnosis of anterior uveitis. The patient exhibited no signs of posterior uveitis. An anterior-chamber paracentesis was performed and analyzed by multiparameter flow cytometry (MFC), showing cells CD45, CD19, CD20, CD22, and CD38 positives, and moderate expression of CD10 with kappa light chain restriction, showing a monoclonal B-cell population. The patient received CHOP-R with intrathecal methotrexate followed by consolidation high dose methotrexate obtaining a complete response which is ongoing. Differential diagnosis between chronic uveitis and ocular lymphoma may be challenging. We advocate anterior-chamber paracentesis in cases of refractory uveitis in patients with hematologic malignancies. © 2016 International Clinical Cytometry Society. © 2016 International Clinical Cytometry Society.

Full Text Available As intoxicações por plantas em animais de produção, no Brasil e no Uruguai são conhecidas desde que os pioneiros Espanhóis e Portugueses introduziram as primeiras cabeças de gado em pastagens naturais da região. As perdas econômicas ocasionadas pelas intoxicações por plantas podem ser definidas como diretas ou indiretas. As perdas diretas são causadas pelas mortes de animais, diminuição dos índices reprodutivos (abortos, infertilidade, malformações, redução da produtividade nos animais sobreviventes e outras alterações devidas a doenças transitórias, enfermidades subclínicas com diminuição da produção de leite, carne ou lã, e aumento à susceptibilidade a outras doenças devido a depressão imunológica. As perdas indiretas incluem os custos de controlar as plantas tóxicas nas pastagens, as medidas de manejo para evitar as intoxicações como a utilização de cercas e o pastoreio alternativo, a redução do valor da forragem devido ao atraso na sua utilização, a redução do valor da terra, a compra de gado para substituir os animais mortos, e os gastos associados ao diagnóstico das intoxicações e ao tratamento dos animais afetados (Riet-Correa et al. 1993, James 1994. As perdas econômicas causadas pelas intoxicações por plantas são difíceis de se estimar por que não existem dados confiáveis sobre todos esses componentes, no entanto, as perdas causadas por mortes são fáceis de determinar quando dispomos de dados elaborados por laboratórios de diagnóstico, sobre a freqüência das causas de mortes dos animais numa determinada região.

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

Science.gov (United States)

Asproudis, Ioannis; Katsanos, Andreas; Kozeis, Nikolaos; Tantou, Alexandra; Konstas, Anastasios G

2017-12-01

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

He was diagnosed with bilateral nongranulomatous uveitis and treated with topical steroid eye drops and posterior sub-Tenon injection of triamcinolone. His visual symptoms were resolved within 1 week, and inflammation resolved within 4 weeks after treatment.

To evaluate the outcomes of changing immunosuppressive therapy for noninfectious uveitis after failure. Retrospective cohort study. Patients with noninfectious uveitis managed at 2 tertiary uveitis clinics in the United Kingdom and Australia. Participants with a history of using immunosuppressive therapy were identified in clinics, and notes were reviewed by doctors trained in uveitis therapy. Each treatment episode/course (starting or changing a therapy) was identified, and demographic details, clinical characteristics, drug used (second-line immunosuppressive agent [ISA] or biologicals), and drug doses were obtained. For each treatment episode, the reasons for changing therapy, corticosteroid-sparing effects, and control of inflammation were determined. A total of 147 patients were identified who underwent 309 different treatment episodes. Fifty-five percent of patients eventually required a change in treatment after their first treatment episode/course. Forty-five episodes involved switching from one ISA to another, with 50% to 100% of these patients achieving "success" (prednisolone ≤10 mg and sustained control) with the new ISA. A combination of ISAs were used in 53 episodes, with "success" being achieved in 50% to 71% of these patients. Biological agents were used in 45 episodes, the most common one being infliximab, which achieved success in 80% of patients. Our data suggest that control of inflammation can be achieved after switching or combining ISAs. Copyright © 2014 American Academy of Ophthalmology. Published by Elsevier Inc. All rights reserved.

Full Text Available The course of uveitis in patients with ankylosing spondylitis (AS does not always correlate with inflammation in the axial skeleton and peripheral joints. Effect of tumor necrosis factor α (TNFα inhibitors on uveitis has been insufficiently studied yet, unlike their effect on the peripheral joints and spine.Objective. To compare the frequency of uveitis attacks in patients with AS during treatment with TNFα inhibitors and the conventional anti-inflammatory therapy.Materials and Methods. The study included 48 patients with AS and recurrent uveitis treated with TNFα inhibitors: 25 – infliximab, 15 – adalimumab, 9 – etanercept; 7 patients received two or more drugs sequentially. Median [25th, 75th percentiles] of the treatment duration was 3 [3.5; 5] years. The duration of treatment since the first attack of uveitis until administration of TNFα inhibitors was 5 [5; 9.7] years. Eighteen patients received only nonsteroidal anti-inflammatory drugs (NSAIDs, 30 patients received NSAIDs and basic anti-inflammatory drugs (DMARDs, including sulfasalazine (n = 23, methotrexate (n = 4, and cyclosporine (n = 4.Results. The median number of uveitis exacerbations during the standard anti-inflammatory therapy was 1 [0.4; 3] per year; during treatment with TNFα inhibitors – 0 [0; 0.5] per year (p = 0.0007. In 19 of 48 patients (40%, no exacerbations of uveitis were registered during therapy with these drugs. The frequency of uveitis attacks in patients treated with infliximab decreased from 1 [0.2; 2.75] to 0.1 [0; 0.8] episodes per year (p = 0.002, adalimumab – from 1.75 [1; 4.5] to 0 [0; 0.07] (p = 0.04, etanercept – from 0.95 [0.5; 1.75] to 0 [0; 0.07] (p = 0.001.Conclusion.

Full Text Available We report a case of a 51-year-old diabetic male who presented with a complaint of intermittent chills and fever that he had experienced for 10 days. No obvious respiratory tract, genitourinary tract, gastrointestinal tract, or skin lesions were observed. Blood culture data were positive for group B β-streptococcus. Transthoracic and transesophageal echocardiography revealed vegetation in the anterior leaflet of the mitral valve. The patient was diagnosed with infective endocarditis (IE and prescribed a parenteral antibiotic. Three days after admission, the patient complained of progressively blurred vision. Slit lamp examination found fine keratic precipitates and aqueous cells in the anterior chambers in both eyes, implying that the patient had uveitis. He was then prescribed a topical steroid for 4 months, and his vision improved gradually. This case is an important reminder that uveitis, not only endophthalmitis, can occur with IE. Treatment for one condition, if misapplied, may worsen the other.

Full Text Available Aim: Juvenile idiopathic arthritis (JIA associated uveitis is one of the most common causes of visual morbidity in children. We report the systemic, clinical and investigational features of a cohort of all cases of JIA associated uveitis seen at our referral uveitis clinic between 1988 and 2004. Study Design: Retrospective case series Materials and Methods: All patients of JIA seen at the uveitis clinic of tertiary eye care hospital, between 1988 and 2004 with minimum follow up of 3 months were included. Complete history and ophthalmic evaluation and findings on each visit were noted. Ocular complications were identified and recorded. Results of laboratory investigations and diagnostic as well as therapeutic procedures were analyzed. A rheumatologist managed systemic status. Results: There were 40 patients (64 eyes with JIA. Thirty four patients (85% had pauciarticular type and 6 patients (15% had polyarticular type of JIA. Complicated cataract and band shaped keratopathy were seen in 38 eyes (63% and 37 eyes (62% respectively. Twenty-two patients (17 bilateral and 5 unilateral were treated with immunosuppressives and in 19 of these patients, the disease went into remission. Twenty-three eyes (38% had improvement in visual acuity while in 27 eyes (45%, the vision remained stable and in 10 eyes (17%, vision deteriorated despite therapy. Conclusion: In India, JIA associated uveitis commonly presented in pauciarticular type with preponderance in males. Rheumatoid arthritis factor and anti nuclear antibodies were not as common as compared to the western population. Among long-term treatment options, immunosuppressives are a better choice. Ocular surgery was performed when mandatory for visual rehabilitation.

To develop a combination surgery for wet age-related macular degeneration and concurrent chronic peripheral uveitis that would include intravitreal injection of Lucentis and cryocerclage of the peripheral retina. A total of 75 patients were examined and divided into 2 groups: the main group (37 patients) and the controls (38 patients). Patients from the main group underwent the new combination surgery, while the controls received intravitreal Lucentis alone (peripheral uveitis was managed therapeutically). It has been found that the new combination method provides a significant and stable improvement in visual acuity (by a factor of 10) and a decrease in the area of central scotoma (by a factor of 2.95) in the postoperative period. The period needed for recovery in the central retinal thickness is also 1.6 times shorter. The new combination surgery for wet age-related macular degeneration and concurrent chronic peripheral uveitis provides rapid reduction of inflammation in the extreme periphery of the fundus and a 1.5 times faster (as compared to traditional methods) primary restoration of topographic anatomy of the retina in the macular region.

HLA-B27 is a transplantation antigen found in a high proportion of patients with ankylosing spondylitis. Recently, an association has been shown to exist between HLA-B27 and acute uveitis, even in the absence of ankylosing spondylitis. We have examined the HLA antigen profile of 45 patients with acute nongranulomatous anterior uveitis and have confirmed this relation. In addition, using 90mtechnetium stannous pyrophosphate we have been able to demonstrate abnormal bone scan in 19 of 30 patients studied. Such abnormalities are limited to the sacroiliac joints but are otherwise the same as those seen in overt ankylosing spondylitis. Seven of the 19 patients did not have HLA-B27. These factors suggest that acute anterior uveitis may often represent a manifestation of a spondylitic diathesis even in the complete absence of any suggestive symptomatic or radiologic change and, in some cases, even though the antigenic marker HLA-B27 may be absent.

Full Text Available Background: Uveitis is one of the most common extra-articular manifestations of juvenile idiopathic arthritis (JIA. Currently, the possibility of reducing the risk of uveitis in children with JIA by using methotrexate has been studied.Objective: Our aim was to analyze the results of treatment of children with JIA by studying the relation between the use of methotrexate and the risk of uveitis.Methods: A retrospective uncontrolled study. The case histories of patients with JIA who were treated for at least 2 years after the onset of the disease were studied. The results of treatment of patients who received and who did not receive methotrexate were studied (standard therapy — non-steroidal anti-inflammatory drugs and intra-articular injections of glucocorticoids. The established cases of uveitis were taken into account.Results: The study analyzed the results of observation of 281 children with JIA. In the methotrexate group, uveitis was detected in 22/191 (11.5%, and in the control group — in 42/90 (46.7% of patients (OR 6.7; 95% CI 3.7–12.3. The time period between the onset of JIA and development of uveitis in two groups under study was the same and equal to 24 (12; 67 and 17 months (7; 35, respectively (p = 0.232. Multivariate regression analysis showed that the main predictors of uveitis were oligoarticular course of JIA (HR = 1.89, positive antinuclear antibody test (HR = 2.14, onset of JIA under the age of 5 (HR = 2.56, female gender (HR = 1.82,and the absence of methotrexate in the therapy (HR = 0.24.Conclusion: The treatment with methotrexate may reduce the risk of uveitis in patients with JIA. To confirm this hypothesis, randomized studies are needed.

To report the outcomes of combined Ahmed glaucoma valve (AGV) placement, intravitreal fluocinolone acetonide implant, and cataract extraction procedure in the treatment of chronic noninfectious uveitis. Retrospective case series of patients with chronic noninfectious uveitis who underwent AGV placement, intravitreal fluocinolone acetonide implantation, and cataract extraction in a single surgical session performed at 1 institution from January 2009 to November 2014. Outcome measures included intraocular pressure (IOP) and glaucoma medication use. Secondary outcome measures included visual acuity, systemic anti-inflammatory medications, number of uveitis flares, and complications. Fifteen eyes of 10 patients were studied, with a mean age of 40.3±15.7 and mean follow-up duration of 26 months (range, 13 to 39 mo). Before surgery, the IOP was 18.5±7.3 mm Hg and patients were using 1.5±1.5 topical glaucoma medications. At the 12-month follow-up, IOP was 12.8±3.2 mm Hg (P=0.01) and patients were using 0.5±0.8 (P=0.03) topical glaucoma medications. At 36 months of follow-up, late, nonsustained hypotony had occurred in 3 eyes (20%), and 1 eye (6%) had received a second AGV for IOP control. Before treatment, patients had 2.7±1.5 uveitis flares in the year before surgery while on an average of 2.1±0.6 systemic anti-inflammatory medications, which decreased to an average of 0.1±0.3 (Pglaucoma medications at 12 months after treatment in patients with chronic uveitis.

Non-infectious uveitis is a sight-threatening inflammatory disease that often necessitates prolonged use of high-dose corticosteroids, resulting in significant systemic side effects. There is a need for efficacious steroid-sparing immunomodulatory therapy for these patients, and the mTOR inhibitors (sirolimus and everolimus) may be contenders for this role. A comprehensive review of preclinical and clinical research on mTOR inhibitors for non-infectious uveitis was performed. Articles were identified by a search of MEDLINE (PubMed/OVID) and EMBASE (OVID) the terms (uveitis OR non-infectious uveitis) AND (mTOR inhibitor OR sirolimus OR everolimus). Assessment of study aims, methods, efficacy outcomes and adverse events was performed. Seven pre-clinical and nine clinical studies were identified. One study in each group was on everolimus, the rest sirolimus. Preclinical studies have been performed in rabbit, rat, mouse and in-vitro models. Clinical studies range from comparative open-label trials to case reports, with reported clinical efficacy ranging from 40% to 100% depending on endpoint assessed. The overall rate of drug-related adverse events (such as ocular irritation, visual floaters, nausea and vomiting) was 0.640 events per patient-year with sirolimus, and 0.111 events per patient-year with everolimus. Published evidence suggests that sirolimus and everolimus may be useful in the management of noninfectious uveitis. Both appear to be well tolerated, especially when locally administered. Further high-quality RCTs adopting standardised end-points are required to definitively determine the efficacy of each agent.

Based on a nationwide database, this study analyzed the influence of methotrexate (MTX), tumor necrosis factor (TNF) inhibitors, and a combination of the 2 medications on uveitis occurrence in juvenile idiopathic arthritis (JIA) patients. Data from the National Paediatric Rheumatological Database in Germany were used in this study. Between 2002 and 2013, data from JIA patients were annually documented at the participating pediatric rheumatologic sites. Patients with a JIA disease duration of treatment on the occurrence of uveitis was evaluated by discrete-time survival analysis. A total of 3,512 JIA patients (mean ± SD age 8.3 ± 4.8 years, 65.7% female, 53.2% antinuclear antibody positive, and mean ± SD age at arthritis onset 7.8 ± 4.8 years) fulfilled the inclusion criteria. Mean ± SD total followup time was 3.6 ± 2.4 years. Uveitis developed in a total of 180 patients (5.1%) within 1 year after arthritis onset. Uveitis onset after the first year was observed in another 251 patients (7.1%). Disease-modifying antirheumatic drug (DMARD) treatment in the year before uveitis onset significantly reduced the risk for uveitis as follows: MTX: hazard ratio (HR) 0.63, P = 0.022; TNF inhibitors: HR 0.56, P uveitis risk (HR 0.29, P uveitis onset. Early MTX use within the first year of disease and the combination of MTX with a TNF inhibitor had the highest protective effect. © 2016 The Authors.

Chronic anterior uveitis is a serious complication of juvenile idiopathic arthritis (JIA); disease flares are highly associated with loss of vision. Leflunomide (LEF) is used successfully for JIA joint disease but its effectiveness in uveitis has not been determined. The aim of this study was to determine whether LEF improves flare rates of uveitis in JIA patients compared to preceding methotrexate (MTX) therapy. A single-centre retrospective study of consecutive children with JIA and chronic anterior uveitis was performed. All children initially received MTX and were then switched to LEF. Demographic, clinical, and laboratory data, dose and duration of MTX and LEF therapy, concomitant medications and rate of anterior uveitis flares, as determined by an expert ophthalmologist, were obtained. Flare rates were compared using a generalized linear mixed model with a negative binomial distribution. A total of 15 children were included (80% females, all antinuclear antibody positive). The median duration of MTX therapy was 51 (range 26-167) months; LEF was given for a median of 12 (range 4-47) months. Anti-tumour necrosis factor (anti-TNF-α) co-medication was given to four children while on MTX. By contrast, LEF was combined with anti-TNF-α treatment in six children. On MTX, JIA patients showed a uveitis flare rate of 0.0247 flares/month, while LEF treatment was associated with a significantly higher flare rate of 0.0607 flares/month (p = 0.008). Children with JIA had significantly more uveitis flares on LEF compared to MTX despite receiving anti-TNF-α co-medication more frequently. Therefore, LEF may need to be considered less effective in controlling chronic anterior uveitis.

Equine recurrent uveitis (ERU) is a common cause of ocular pain and blindness in horses. Leptospira spp. have been commonly implicated in the pathophysiology of ERU in mainland Europe and the USA. No recent studies have been carried out in the UK, but Leptospira is reported not to be a major factor in the aetiology of ERU in the UK. To establish the prevalence of Leptospira-associated ERU in the UK and to identify the serovars involved in these cases; to compare serum vs. aqueous humour antibody levels in cases and controls in order to confirm the diagnosis of Leptospira-associated ERU, and to assess the usefulness of serology alone as a confirmatory test for Leptospira-associated ERU in the UK. Case-control study. Eyes enucleated for clinical reasons in ERU-affected horses were collected. Blood and aqueous humour were obtained to determine antibody levels against a variety of Leptospira serovars and C-values (aqueous humour value/serum value) were calculated. In addition, eyes, blood and aqueous humour were obtained from control cases for comparison. Histopathology was performed in all eyes to confirm uveitis in each case. Differences in seroprevalences between ERU and control cases and between Leptospira- and non-Leptospira-associated ERU cases were calculated. A total of 30 ERU and 43 control eyes were analysed. Of the ERU eyes, only two had a C-value of >4 (prevalence of Leptospira-associated uveitis: 6.7%). Serovars hardjo and javanica were detected. There was no difference in seroprevalence between horses with uveitis and control cases (65.5% and 41.9%, respectively; P = 0.11) or between Leptospira- and non-Leptospira-associated uveitis cases (100% and 63.0%, respectively; P = 0.52). The study was limited by low case numbers. Eyes were presented at different stages of disease. The only test used to detect Leptospira was the microscopic agglutination test. Leptospira-associated ERU is uncommon in the UK. Serology alone may not help to definitively diagnose

Full Text Available Hayate Nakagawa, Hidetaka Noma, Osamu Kotake, Ryosuke Motohashi, Kanako Yasuda, Masahiko Shimura Department of Ophthalmology, Tokyo Medical University Hachioji Medical Center, Tokyo, Japan Background: A few reports have described ocular complications of influenza A infection, such as impaired ocular movement, parasympathetic ocular nerve, keratitis, macular lesion, and frosted branch angiitis. We encountered a rare case of acute anterior uveitis and optic neuritis associated with influenza A infection. Case presentation: A 70-year-old man presented with symptoms of upper respiratory tract infection. A rapid diagnostic test showed a positive result for influenza A. At the same time, he developed ocular symptoms including blurred vision with optic disk edema and hemorrhage in the left eye, and bilateral red eyes. Multiplex polymerase chain reaction performed on aqueous humor sample detected no viral infection. Visual field testing with a Goldmann perimeter showed central and paracentral scotomas in the left eye. In addition to antiviral agent (oseltamivir phosphate 75 mg, the patient was prescribed topical prednisolone acetate ophthalmic suspension eye drops every 5 hours and high-dose intravenous methylprednisolone 1,000 mg daily for 3 days. Two months later, his best-corrected visual acuity improved to 20/50 with regression of visual field defects in his left eye. Conclusion: We report a case of bilateral acute anterior uveitis and unilateral optic neuritis concomitant with influenza A infection. Topical and systemic corticosteroids were effective to resolve acute anterior uveitis and neuritis. Analysis of aqueous humor sample suggested that acute anterior uveitis and optic neuritis in this case were not caused by influenza A virus infection per se but by autoimmune mechanism.

Consecutive eyes with active noninfectious uveitis were injected with IVA at 0, 2, then every 4 weeks for total of 26 weeks. Six out of 7 patients (12 of 13 eyes) completed 26 weeks of treatment. One patient (1 eye) failed treatment. Seven out of 12 eyes had improvement of ≥2 ETDRS lines. Three out of three eyes had resolution of anterior chamber cells. And 9 of 10 eyes with vitreous haze had zero haze at 26 weeks. Five out of 8 eyes with macular edema had complete resolution. Median fluorescein angiography score improved from 14 to 4 on last follow-up. IVA was effective in controlling the inflammation, decreasing the macular edema, and improving the best corrected visual acuity in the majority of eyes in this series.

Acute anterior uveitis (AAU) is the most common form of uveitis, accounting for approximately 90% of all cases. Half of all cases of AAU are HLA-B27 positive. The disease is typically acute in onset, unilateral, nongranulomatous inflammation involving the iris and ciliary body, with a tendency to recurrent attacks. Approximately 50% of all patients with HLA-B27 AAU develop an associated seronegative arthritis (SNA), while approximately 25% of the patients initially diagnosed with HLA-B27 SNA develop AAU. Environmental factors play a critical role in the pathogenesis of AAU; in particular, bacterial triggers have been strongly implicated in the development of this disease. Topical corticosteroids and cycloplegic agents remain the cornerstones of treatment for AAU. Salazopirine and methotrexate are effective in decreasing recurrent attacks. Biological agents such as anti-TNF and anti-CD20 therapy may be effective in refractory severe AU but are rarely required.

To evaluate adalimumab therapy in children with uveitis. The electronic health records of pediatric patients diagnosed with uveitis and treated with adalimumab therapy were reviewed retrospectively. Demographic information, site and degree of intraocular inflammation, visual acuity, underlying systemic disorders, duration of therapy, side effects, and ability to obtain steroid-free remission were recorded. A total of 17 patients were included, 16 patients with anterior uveitis and 1 with panuveitis; 14 patients had bilateral disease. Juvenile idiopathic arthritis had been diagnosed in 14 patients, sarcoidosis in 1 patient, and idiopathic etiology in 2 patients. Of the 17 patients, 13 (about 77%) achieved steroid-free remission, and 4 did not. Six patients flared after discontinuation of adalimumab, with evidence of inflammation noted 3-7 months later. Adalimumab therapy was of 12-64 months' duration (mean, 36 months). At the time of initiation, 14 patients were using other agents concomitantly with adalimumab; 3 patients were on adalimumab monotherapy. At 1 year's follow-up, 12 patients were using combination therapy, and 3 patients were on adalimumab monotherapy: 11 patients had no evidence of inflammation. Side effects included pain at site of injection in 3 patients, anemia in 1 patient, and depression in 1 patient. In our study cohort, adalimumab was effective in inducing steroid-free remission. It was well tolerated, especially in combination with other immunomodulatory agents. The dosing and the interval can be adjusted to further improve inflammation control.

Full Text Available AIM: To analyze the etiology, therapeutic effects,risk of relapse and prognosis of acute anterior uveitis.MEHTODS: Medical history of 215 patients with acute anterior uveitis who underwent treatment in Department of Ophthalmology, People's Hospital of Fenghua was collected, together with results of clinical examinations and auxiliary examinations. The data were studied in terms of therapeutic effects, etiological factors, prognosis and relapse rate. RESULTS: In 85 cases(39.5%, the cause was identified, and among the among the most frequent causes were traumatic or surgical injury, viral infection and glaucomatocyclitic crisis. After treatment, the best corrected visual acuity was no less than 1.0 in 153 cases(71.2%, between 0.5 and 1.0 in 55 cases(25.6%, between 0.3 and 0.5 in 4 cases(1.9%, between 0.05 and 0.3 in 2 cases(0.9%, and less than 0.05 in 1 case(0.5%. During the follow-up of more than 6 months, relapse occurred in 4 cases(1.9%during 4-6 months, in 7 cases(3.2%during 7-12 months, in 10 cases(4.7%during 13-24 months, and in 3 cases(1.4%during 25-60 months. CONCLUSION: The etiology of acute anterior uveitis is complicated and mostly idiopathic. Vision prognosis is good after treatment, but therelapse rate is high and can cause visual impairment, so better understanding should be gained of its relapse and its prevention and early treatment should be emphasized.

The aim of this study was to quantify the proportion of regulatory T cells (Treg ) and cytokine expression by peripheral blood mononuclear cells (PBMCs) in patients with active non-infectious uveitis, and to evaluate the effect of in-vitro treatment with infliximab, dexamethasone and cyclosporin A on Treg levels and cytokine production in PBMCs from uveitis patients and healthy subjects. We included a group of 21 patients with active non-infectious uveitis and 18 age-matched healthy subjects. The proportion of forkhead box protein 3 (FoxP3)(+) Treg cells and intracellular tumour necrosis factor (TNF)-α expression in CD4(+) T cells was determined by flow cytometry. PBMCs were also either rested or activated with anti-CD3/anti-CD28 and cultured in the presence or absence of dexamethasone, cyclosporin A and infliximab. Supernatants of cultured PBMCs were collected and TNF-α, interleukin (IL)-10, IL-17 and interferon (IFN)-γ levels were measured by enzyme-linked immunosorbent assay (ELISA). No significant differences were observed in nTreg levels between uveitis patients and healthy subjects. However, PBMCs from uveitis patients produced significantly higher amounts of TNF-α and lower amounts of IL-10. Dexamethasone treatment in vitro significantly reduced FoxP3(+) Treg levels in PBMCs from both healthy subjects and uveitis patients, and all tested drugs significantly reduced TNF-α production in PBMCs. Dexamethasone and cyclosporin A significantly reduced IL-17 and IFN-γ production in PBMCs and dexamethasone up-regulated IL-10 production in activated PBMCs from healthy subjects. Our results suggest that PBMCs from patients with uveitis express more TNF-α and less IL-10 than healthy subjects, and this is independent of FoxP3(+) Treg levels. Treatment with infliximab, dexamethasone and cyclosporin A in vitro modulates cytokine production, but does not increase the proportion of FoxP3(+) Treg cells. © 2014 British Society for Immunology.

Ocular inflammatory disorders constitute a sight-threatening group of diseases that might be managed according to their severity. Their treatment guidelines experience constant changes with new agents that improve the results obtained with former drugs. Nowadays we can make use of a five step protocol in which topical, periocular and systemic corticosteroids remain as the main therapy for non infectious uveitis. In addition, immunosuppresive drugs can be added in order to enhance the anti-inflammatory effects and to develop the role of corticosteroid-saving agents. These can be organized in four other steps: Cyclosporine and Methotrexate in a second one; Azathioprine, Mycophenolate Mofetil and Tacrolimus in a third step; biological anti-TNF drugs in fourth position; and a theoretical last one with Cyclophosphamide and Chlorambucil. In the present review we go through the main characteristics and complications of all these treatments and make a rational of this five-step treatment protocol for non infectious posterior uveitis.

Full Text Available Aims: To report our experiences using Ozurdex, a biodegradable implant, containing 0.7 mg of dexamethasone in the treatment of noninfectious intermediate uveitis. Settings and Design: Retrospective study design. Methods: We conducted a retrospective study of medical records of patients with noninfectious intermediate uveitis having either cystoid macular edema (CME or vitritis who were not responsive to standard treatment and subsequently received Ozurdex implant from March 2011 to April 2013. The outcomes measured were best-corrected visual acuity, central retinal thickness (CRT, and vitreous haze score. Statistical Analysis Used: Paired t-test was used to test the significance of difference between quantitative variables. A P < 0.05 is taken to denote significant relationship. Results: Twenty eyes of 15 patients with mean age of 39.8 years who received Ozurdex implant were included in the study. The mean baseline visual acuity improved from 0. 666 logarithm of the minimum angle of resolution (logMAR units to 0.479 logMAR units at 6 weeks after the implant. The mean CRT improved from 536.1 to 361.4 microns at 6 weeks postimplant both parameters were statistically significant. The ocular inflammation was controlled in almost all the patients. Cataract and raised intraocular pressure were documented complications. Conclusion: Ozurdex implant is a promising treatment option and efficient in controlling the inflammation and CME in cases of noninfectious intermediate uveitis not responding to standard treatment.

To evaluate the rate of immunogenicity induced by adalimumab and its relationship with drug serum levels and clinical responses in patients with noninfectious uveitis. Prospective observational study. Consecutive patients from 1 referral center who initiated treatment with adalimumab for active noninfectious uveitis resistant to conventional therapy. All patients received 40 mg adalimumab every other week. Patients were evaluated clinically and immunologically before and after 4, 8, and 24 weeks of treatment. Clinical evaluation included assessment of changes in visual acuity, degree of inflammation in the anterior chamber and vitreous cavity, central macular thickness, and retinal angiographic leakage. Immunologic evaluation included assessment of serum trough adalimumab and antibodies against adalimumab (AAA) levels and class II HLA typing. Twenty-five patients were enrolled. Overall, 18 of 25 patients (72%) showed a favorable clinical response to adalimumab therapy. Eleven patients (44%) achieved a complete response and 7 (28%) achieved a partial response. However, 7 of 25 patients (28%) were considered nonresponders. Median trough adalimumab serum levels were higher in responders than in nonresponders (P uveitis outcome was observed only in patients with permanent AAA+, which correlated with undetectable adalimumab trough levels (P = 0.014). Treatment of noninfectious uveitis with adalimumab is associated with high rates of favorable clinical response. Overall, adalimumab trough levels were higher in responder patients. Development of permanent AAA was associated with undetectable trough adalimumab levels and worse uveitis outcome. Immunogenicity was more common in patients in whom uveitis was associated with a systemic disease and was not influenced by concomitant immunosuppressors.

The chemical structure of voclosporin is similar to that of cyclosporine A, with a difference in one amino acid, leading to superior calcineurin inhibition and less variability in plasma concentration. Compared with placebo, voclosporin may significantly reduce inflammation and prevent recurrences of inflammation in patients with noninfectious uveitis. Future studies have to show if these advantages are accompanied by greater clinical efficacy and fewer side effects compared with the classic calcineurin inhibitors.Keywords: uveitis, immunosuppression, voclosporin

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children. Children with JIA are at risk of inflammation of the uvea in the eye (uveitis). Overall, 20% to 25% of paediatric uveitis is associated with JIA. Major risk factors for development of uveitis in JIA are oligoarticular pattern of arthritis, an age at onset of arthritis of less than seven years of age, and antinuclear antibody positivity. In the initial stages of mild to moderate inflammation the uveitis is asymptomatic. This has led to current practice of screening all children with JIA for uveitis. Approximately 12% to 38% of patients with JIA develop uveitis in seven years following onset of arthritis. In 30% to 50% of children with JIA-associated uveitis structural complications are present at diagnosis. Furthermore about 50% to 75% of those with severe uveitis will eventually develop visual impairment secondary to ocular complications such as cataract and glaucoma. Defining the severity of inflammation and structural complications in uveitis patients is now possible following Standardised Uveitis Nomenclature (SUN) guidelines, and modified to incorporate the consensus of end point and outcome criteria into the design of randomised trials. Despite current screening and therapeutic options (pre-biologics) 10% to 15% of children with JIA-associated uveitis may develop bilateral visual impairment and certified legally blind. To date, there remains no controlled trial evidence of benefits of biologic therapy. This study will randomise 154 patients aged 2 to 18 years with active JIA-associated uveitis (despite methotrexate (MTX) treatment for at least 12 weeks). All participants will be treated for 18 months, with follow up of 3 years from randomisation (continuing on MTX throughout). All participants will receive a stable dose of MTX and in addition either adalimumab (20 mg/0.8 ml for patientstreatment of juvenile idiopathic arthritis associated uveitis. ISRCTN10065623.

Full Text Available The efficiency of incorporating genetically engineered biological agents (GEBAs into a combination treatment regimen for rheumatic diseases (RD (juvenile idiopathic arthritis, Behcet's disease in relation to associated uveitis of varying severity was studied in 92 children aged 2 to 17 years. The follow-up lasted 1.5 to 49 months. Twenty-three patients took consecutively 2 to 5 GEBAs. When infliximab was used, remission of uveitis occurred in 21% of 38 children and the disease activity and/or recurrence rates reduced in an additional 21%. These were in 45 and 38.6% of 44 patients on adalimumab (ADA and in 27.8 and 27.8% of 18 patients on abatacept, respectively. There was an association of the efficiency of therapy with the severity of uveitis at the start of treatment. The use of ADA induced a steady remission of panuveitis resistant to therapy with glucocorticoids and cyclosporine in both patients with Behcet's disease. One of 4 rituximab-treated patients achieved a steady remission. Tocilizumab therapy caused an exacerbation of uveitis in 1 patient. The postoperative period showed no inflammatory complications in most cases (37 operations, 26 eyes, 20 patients. No local adverse reactions were seen; systemic reactions occurred in 14% of the patients, this caused GEBAs to be discontinued in 7%. There is evidence for a need for further investigations into the efficacy of GEBAs in RD-associated uveitis in children in order to define success criteria, differentiated indications, and therapy regimens.

Full Text Available Abstract Background Lutein is an important eye-protective nutrient. This study investigates the protective effects and mechanisms of lutein on lipopolysaccharides (LPS-induced uveitis in mice. Methods Lutein, suspended in drinking water at a final concentration of 12.5 and 25 mg/mL, was administered to mice at 0.1 mL/10 g body weight for five consecutive days. Control and model group received drinking water only. Uveitis was induced by injecting LPS (100 mg per mouse into the footpad in the model and lutein groups on day 5 after the last drug administration. Eyes of the mice were collected 24 hours after the LPS injection for the detection of indicators using commercial kits and reverse transcription-polymerase chain reaction. Results LPS-induced uveitis was confirmed by significant pathological damage and increased the nitric oxide level in eye tissue of BALB/C mice 24 hours after the footpad injection. The elevated nitric oxide level was significantly reduced by oral administration of lutein (125 and 500 mg/kg/d for five days before LPS injection. Moreover, lutein decreased the malondialdehyde content, increased the oxygen radical absorbance capacity level, glutathione, the vitamin C contents and total superoxide dismutase (SOD and glutathione peroxidase (GPx activities. Lutein further increased expressions of copper-zinc SOD, manganese SOD and GPx mRNA. Conclusion The antioxidant properties of lutein contribute to the protection against LPS-induced uveitis, partially through the intervention of inflammation process.

To assess the long-term efficacy of the most widely used anti-tumor necrosis factor alpha (TNFα) agents for treatment of HLA-B27-positive ankylosing spondylitis (AS)-related uveitis. Retrospective cohort study. The medical records of 143 patients with HLA-B27-positive AS who visited Seoul St. Mary's Hospital and were taking an anti-TNFα agent for at least 1 year were studied. Subjects were divided into 3 groups according to anti-TNFα treatment: Group 1 (infliximab, 66), Group 2 (adalimumab, 45), and Group 3 (etanercept, 32). Mean age was 41.0 ± 13.0 years, and 97 patients (67.8%) were male. Mean follow-up period was 70.6 ± 37.9 months. In cases of active ocular inflammation at the onset of anti-TNFα treatment, patients showed improved activity of uveitis after 24.0 ± 15.0 days (Group 1), 17.9 ± 6.0 days (Group 2), and 25.9 ± 18.0 days (Group 3). After the anti-TNFα treatment, 71 of 94 patients (32 [76.2%] in Group 1, 26 [78.8%] in Group 2, and 13 [68.4%] in Group 3) remained without uveitis relapse. A reduction in the number of systemic medications was achieved in 129 patients (90.2%). Twenty-eight cases of minor side effects were observed, and 4 cases were tuberculosis leading to discontinuation of anti-TNFα treatment. Infliximab, adalimumab, and etanercept were effective for treating and reducing the number of uveitis relapses in HLA-B27-positive AS. However, the risk of serious infections was noted, so ophthalmologists should consider the possibility that prolonged use of biologic agents may result in systemic side effects.

To assess the outcomes of the intravitreal administration of methotrexate in uveitis. Multicenter, retrospective interventional case series of patients with noninfectious uveitis. Thirty-eight eyes of 30 patients were enrolled, including a total of 54 intravitreal injections of methotrexate at a dose of 400 µg in 0.1 mL. The primary outcome measure was visual acuity. Secondary outcome measures included control of intraocular inflammation and cystoid macular edema, time to relapse, development of adverse events, and levels of systemic corticosteroid and immunosuppressive therapy. Methotrexate proved effective in controlling intraocular inflammation and improving vision in 30 of 38 eyes (79%). The side effect profile was good, with no reported serious ocular adverse events and only one patient having an intraocular pressure of >21 mmHg. Of the 30 eyes that responded to treatment, 8 relapsed, but 22 (73%) entered an extended period of remission, with the Kaplan-Meier estimate of median time to relapse for the whole group being 17 months. The eight eyes that relapsed were reinjected and all responded to treatment. One eye relapsed at 3 months, but 7 eyes again entered extended remission. Of the 14 patients on systemic therapy at the start of the study, 8 (57%) were able to significantly reduce this following intravitreal methotrexate injection. In patients with uveitis and uveitic cystoid macular edema, intravitreal MTX can effectively improve visual acuity and reduce cystoid macular edema and, in some patients, allows the reduction of immunosuppressive therapy. Some patients relapse at 3 to 4 months, but a large proportion (73%) enter an extended period of remission of up to 18 months. This larger study extends the results obtained from previous smaller studies suggesting the viability of intravitreal methotrexate as a treatment option in uveitis.

To investigate the correlation between clinical features of ankylosing spondylitis (AS) and different human leukocyte antigen (HLA)-B27 subtypes. We conducted a cross-sectional study of 216 patients with AS. HLA-B27 and its subtypes were detected by polymerase chain reaction with sequence specific primer (PCR-SSP). Clinical features were compared between the different HLA-B27 subtypes. A meta-analysis on uveitis frequencies in AS patients with HLA-B*2705 vs 2704 was performed. The most prevalent subtypes of HLA-B27 were HLA-B*2704 (66.1%) and HLA-B*2705 (32.2%). There were 57 HLA-B27-positive AS patients with the history of uveitis; 45 were B*2704 and 12 were B*2705. Patients with B*2704 had more uveitis than B*2705 (p = 0.021). After meta-analysis, there was no significant difference in the presence of uveitis between HLA-B*2704 and HLA-B*2705. AS patients with B*2704 have a higher risk of uveitis than AS with B*2705 in a north Chinese people.

In 2012, a European initiative called S ingle Hub and Access point for pediatric Rheumatology in Europe (SHARE) was launched to optimise and disseminate diagnostic and management regimens in Europe for children and young adults with rheumatic diseases. Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children and uveitis is possibly its most devastating extra-articular manifestation. Evidence-based guidelines are sparse and management is mostly based on physicians' experience. Consequently, treatment practices differ widely, within and between nations. To provide recommendations for the diagnosis and treatment of JIA-associated uveitis. Recommendations were developed by an evidence-informed consensus process using the European League Against Rheumatism standard operating procedures. A committee was constituted, consisting of nine experienced paediatric rheumatologists and three experts in ophthalmology from Europe. Recommendations derived from a validated systematic literature review were evaluated by an Expert Committee and subsequently discussed at two consensus meetings using nominal group techniques. Recommendations were accepted if >80% agreement was reached (including all three ophthalmologists). In total, 22 recommendations were accepted (with >80% agreement among experts): 3 on diagnosis, 5 on disease activity measurements, 12 on treatment and 2 on future recommendations. The SHARE initiative aims to identify best practices for treatment of patients suffering from JIA-associated uveitis. Within this remit, recommendations for the diagnosis and treatment of JIA-associated uveitis have been formulated by an evidence-informed consensus process to suggest a standard of care for JIA-associated uveitis patients throughout Europe. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Collagen, type II, alpha 1, versican (VCAN), frizzled family receptor 4, low density lipoprotein receptor-related protein 5, tetraspanin 12, and Norrie disease (pseudoglioma) genes were screened with direct sequencing. The index case was initially referred for unexplained severe and chronic postoperative bilateral uveitis following a standard cataract surgery procedure. Clinical examination of the proband revealed an optically empty vitreous with avascular vitreous strands and veils, features highly suggestive of WS. The systematic familial ophthalmologic examination identified three additional unsuspected affected family members who also presented with the WS phenotype, including uveitis for one of them. We identified a novel c.4004-6T>A nucleotide substitution at the acceptor splice site of intron 7 of the VCAN gene that segregated with the disease phenotype. We present a family with WS with typical WS features and intraocular inflammatory manifestations associated with a novel splice site VCAN mutation. Beyond the structural role in the retinal-vitreous architecture, versican is also emerging as a pivotal mediator of the inflammatory response, supporting uveitis predisposition as a clinical manifestation of WS.

To study the value of methotrexate (MTX) and the requirement for additional anti-inflammatory drugs for the treatment of severe chronic iridocyclitis associated with juvenile idiopathic arthritis (JIA). Institutional study of 35 consecutive patients with JIA started on MTX as the single systemic immunosuppressive drug for the treatment of associated iridocyclitis. The clinical epidemiologic data, course of visual acuity (VA), development of complications, and the need for additional anti-inflammatory drugs were analyzed. Mean follow-up with MTX treatment was 27.6 months. Uveitic complications were present in 31 patients before MTX treatment. With MTX, quiescence of uveitis was obtained with (n=21) or without (n=4) additional topical steroids. Additional systemic immunosuppressive drugs were required in another 7 patients: cyclosporine A (n=4), azathioprine (n=1), infliximab (n=1), or etanercept (n=1). Three patients had active uveitis at the end of the follow-up period. During MTX therapy, uveitis first developed in the unaffected fellow eyes in 2 patients, and secondary glaucoma or ocular hypertension occurred in 7 patients. The VA deteriorated in 6, improved in 13, and was stable in the remaining eyes. The data suggest that MTX is very effective in controlling inflammation of uveitis in patients with JIA. However, additional topical steroids or systemic immunosuppressive drugs are often required.

To investigate the causes of endogenous uveitis in cats presenting to referral ophthalmology clinics in North Carolina. Medical records of cats diagnosed with endogenous uveitis at North Carolina State University's College of Veterinary Medicine (NCSU-CVM) or Animal Eye Care Associates of Cary, NC between 2003 and 2015 were reviewed. Inclusion criteria were cats that had complete diagnostic workups, including clinical, clinicopathological, serological, and histopathological data, as well as imaging modalities. Serology was consistently completed for feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), feline coronavirus (FCoV), Toxoplasma gondii, and Bartonella spp. One hundred and twenty cats met the inclusion criteria. Seroprevalence of FeLV (2.7%), FIV (7.3%), FCoV (34.7%), T. gondii (23.7%), and Bartonella spp. (43.2%) was observed, with a combined seroprevalence of 59.2%. Nineteen cats (15.8%) were diagnosed with feline infectious peritonitis (FIP) based on clinical, hematological, serological, histopathological, and necropsy findings. The average age of all cases was 7.62 years, while the average age of cats diagnosed with FIP was 1.82 years. Neoplasia was diagnosed in six cats (5.0%). No underlying etiology was found in 49 cats (40.8%). Both idiopathic and neoplastic causes of uveitis were less prevalent than previously reported in studies, while seropositivity was higher than previously reported for the study area. This may be due to improved diagnostic capabilities or that cats with infectious disease were more likely to be referred. Because of the high prevalence of FIP, young cats with uveitis should be evaluated for hyperglobulinemia and FCoV serology should be performed as minimal diagnostics. © 2015 American College of Veterinary Ophthalmologists.

Full Text Available Las rickettsiosis son entidades clínicas de tipo zoonótico, causadas por bacterias intracelulares estrictas de los géneros Rickettsia y Orientia, pertenecientes a la familia Rickettsiaceae. Su ecología está determinada por factores ambientales y la presencia de vectores específicos que condicionan el establecimiento y la epidemiología en diferentes regiones del mundo. En las Américas, durante el siglo XX, únicamente eran reconocidas tres de estas enfermedades: la fiebre manchada de las Montañas Rocosas, el tifus epidémico y el tifus endémico. Sin embargo, apartir del año 2000 se han descrito mas de 10 especies diferentes previamente desconocidas en este continente, tanto en artrópodos como en casos clínicos, hecho que permite clasificarlas como entidades clínicas emergentes y reemergentes. Dadas las manifestaciones clínicas de las enfermedades causadas por rickettsias, siendo la gran mayoría inespecíficas y, por lo mismo, compartidas con otras enfermedades infecciosas, especialmente virales y bacterianas, han sido enmarcadas entre los diagnósticos diferenciales del síndrome febril agudo, tanto en áreas urbanas como tropicales. En la actualidad, se cuenta con métodos diagnóstico sdirectos e indirectos, que son útiles en la identificación del agente infeccioso, en este caso, causante de rickettsiosis.   doi: http://dx.doi.org/10.7705/biomedica.v33i0.1466

O animal apresentou sinais clínicos nos quartos mamárias anteriores e queda acentuada na produção de leite. Após o diagnóstico inicial, o animal foi observado durante onze meses, do início da manifestação da doença até 12 dias após o parto. Exames microbiológicos do leite foram realizadas aos 7, 30, 39, 49, 65, 326 e 331 dias após o isolamento inicial, sendo os dois últimos exames realizados 7 e 12 dias após o parto. As amostras de P. zopfii isoladas apresentaram resistência in vitro a: ampicilina, canamicina, cefatoridina, enrofloxacina, estreptomicina, gentamicina, neomicina, oxacilina, penicilina, sulfonamidas e trimetoprim x sulfametoxazol. Foi avaliada a susceptibilidade in vitro das amostras de P. zopfii a um produto natural constituído de extrato de sementes de frutas cítricas, obtido comercialmente. A menor concentração que inibiu totalmente a alga foi 1:500. Recomendou-se um tratamento com a diluição a 1:200 do extrato em solução fisiológica estéril contendo timerosal a 1:30.000 como conservante, em doses diárias de 20ml, por via intramamária. O tratamento foi realizado inicialmente durante sete dias. Após este período houve redução, mas não a completa eliminação dos organismos do leite. Foi, então, recomendado mais um período de 15 dias de tratamento, de modo semelhante ao primeiro. Trinta e nove dias após o diagnóstico inicial não foi mais isolado P. zopfii do leite dos quartos afetados e a produção retornou a níveis semelhantes de antes da infecção. Amostras de leite naturalmente infectadas foram congelados a -20°C. Células viáveis de P. zopfii foram recuperadas de amostras mantidas até 38 dias nestas condições.A clinical case of mastitis caused by Prototheca zopfii in a cow from a dairy herd located in the region of Zona da

Full Text Available Este trabajo describe el desarrollo y normalización de una técnica inmunoenzimática para el diagnóstico indirecto de la Fiebre Tifoidea. El método permite un análisis simple y objetivo de los resultados. La reacción enzimática es proporcional a la concentración de anticuerpos en el suero contra el antígeno somático-0, por tanto, el método es cuantitativo. Por lo demás, la técnica tiene un alto grado de especificidad para Salmonella typhi, ya que los sueros de pacientes con Salmonelosis causada por Salmonella enteritidis serotipos paratyphi A, B y typhimurium dieron resultados negativos, en forma similar a los presentados por el grupo control antes de la vacunación específica. Los resultados obtenidos con esta técnica permitieron definir el nivel de anticuerpos que puede presentar una población control supuestamente sana frente a los niveles inducidos por la enfermedad. Los resultados postvacunales en el grupo control mostraron títulos sorprendentemente bajos; un análisis de este fenómeno se presentó en forma amplia. Igualmente se proponen futuras investigaciones sobre este campo.

To evaluate the effect of an intravitreally applied anti-IL-6 antibody for the treatment of experimental autoimmune uveitis (EAU). EAU was induced in female B10.RIII mice by Inter-Photoreceptor-Binding-Protein (IRBP) in complete Freund's adjuvant, boosted by Pertussis toxin. Single blinded intravitreal injections of anti-IL-6 antibody were applied 5-7days as well as 8-10days (3day interval) after EAU induction into the randomized treatment eye and phosphate buffered saline (PBS) into the fellow control eye. Clinical and fluorescein angiography scoring (6 EAU grades) was done at each injection day and at enucleation day 14. Enucleated eyes were either scored histologically (6 EAU grades) or examined by ELISA for levels of IL-6, IL-17 and IL-6 soluble Receptor (sIL-6R). Uveitis developed in all 12 mice. Clinical uveitis score was significantly reduced (p=0.035) in treated eyes (median 2.0, range 0-4.0, n=12) compared to the fellow control eyes (median 3.0, range 1.0-4.0, n=12). Angiography scores were reduced in 9/12 treated eyes and histological scores in 3/4 treated eyes compared to the fellow control eyes. Cytokine levels were determined in 8 mice, of which 4 responded to anti-IL-6 treatment and 4 did not respond. All mice responding to treatment had a significant reduction of IL-6 (ptreatment significantly attenuates experimental autoimmune uveitis in mice.

We compared the anti-inflammatory effects of bosentan and dexamethasone in endotoxin-induced uveitis (EIU). Endotoxin-induced uveitis was induced by subcutaneous injection of lipopolysaccharide (LPS, 200 μg) in Wistar rats. Rats were divided randomly into 10 groups (n = 6). Bosentan at doses of 50 and 100 mg/kg were administered orally 1 hour before and 12 hours after LPS injection, and dexamethasone was administered by intraperitoneally 30 minutes before and 30 minutes after LPS injection at a dose of 1 mg/kg. Data were collected at two time points for each control and treatment; animals were killed at either 3 or 24 hours after LPS injection. Histopathologic evaluation and aqueous humour measurements of TNF-α level were performed, and endothelin-1 (ET-1), inducible nitric oxide synthase (iNOS), and endothelin receptor A and B (EDNRA and B) expression were analyzed. The group treated with 100 mg/kg bosentan at 24 hours displayed significantly milder uveitis and fewer inflammatory cells compared to LPS-injected animals, and there were similar findings in the dexamethasone-treated group at 24 hours. The TNF-α levels in the dexamethasone treatment group were lower than those in the LPS-induced uveitis control group (P treatment groups at 3 and 24 hours after LPS administration. Bosentan treatment at doses of 50 and 100 mg/kg significantly decreased iNOS expression compared to LPS-injected animals (P treatment groups was statistically significantly lower than that in the LPS-induced uveitis control group at 3 and 24 hours after LPS administration (P < 0.05). Bosentan reduces intraocular inflammation and has similar effects as dexamethasone in a rat model of EIU. Copyright 2014 The Association for Research in Vision and Ophthalmology, Inc.

To compare interferon (IFN) beta with methotrexate (MTX) in the treatment of intermediate uveitis with macular edema. Monocentric, prospective, randomized, controlled clinical trial. Specialized uveitis center at the University of Heidelberg. PATIENT OR STUDY POPULATION: Patients with either primary intermediate uveitis or uveitis associated with multiple sclerosis. MAIN INCLUSION CRITERIA: Visual acuity of 20/30 or worse (0.2 logarithm of the minimal angle of resolution) and macular edema of more than 250 μm (central 1-mm in optical coherence tomography; Stratus). Randomization into either IFN beta 44 μg subcutaneously 3 times weekly or 20 mg MTX subcutaneously once weekly. At 3 months, the primary outcome parameter of mean change in visual acuity was evaluated and efficacy was determined. Secondary parameters were macular edema by optical coherence tomography, inflammatory activity, and retinal sensitivity by microperimetry (MP-1; Nidek). In case of treatment failure, switching to the other treatment arm was possible. Nineteen patients were included. Ten were randomized to MTX, and 9 were randomized to IFN beta. At 3 months, visual acuity improved a mean 0.31 logarithm of the minimal angle of resolution (range, -0.02 to -0.96, 15.6 letters on the Early Treatment Diabetic Retinopathy Study chart) in the IFN beta group versus a mean 0.09 logarithm of the minimal angle of resolution (range, 0.12 to -0.38, 4.7 letters) in the MTX arm (P = .0435, Mann-Whitney U test). Macular thickness decreased by a mean of 206 μm (range, -41 to -416 μm) in the IFN arm, but increased by 47 μm (range, 108 to -28 μm) in the MTX group (P treatment of macular edema in the setting of intermediate uveitis.

To examine antigen-stimulated cytokine production by Behçet disease patients (BD) before and after infliximab infusion. PBMCs were obtained before and after infliximab infusion in BD patients with or without recurrent uveitis during at least 1 year of infliximab therapy, and from healthy subjects. PBMCs were cultured with IRBP, and Th-related cytokines in cultures were measured. Levels of IL-4, IL-6, IL-10 IL-17A, IL-17F, IL-31, IFN-γ, and TNFα were higher in BD before infliximab infusion than in healthy subjects, and these levels were the highest in BD with recurrent uveitis. After infliximab infusion, these cytokine levels were reduced to a greater extent in BD without recurrent uveitis than in BD with recurrence. Th-related cytokines produced by IRBP-stimulated PBMCs were elevated in BD, and infliximab infusion suppressed these cytokines to a greater extent in BD without recurrent uveitis than in those with recurrence.

Introduction Serum uric acid level increases in many inflammatory conditions. Uric acid triggers the vascular inflammation and artery damage, which causes to an increased risk of endothelial dysfunction and atherosclerosis. It is not clear in the literature whether uric acid contributes to uveitis by similar mechanisms. We investigated whether uric acid level increases in Behcet's disease patients with thrombosis or anterior uveitis. Patients and methods We reviewed the medical records of 914 Behcet's disease. After screening for exclusion criteria, there were 50 Behcet's disease patients with thrombotic complication and as the control group 202 BD patients without any vascular complication were included to the study. In the Anterior uveitis group, there were 53 Behcet's disease patients. The Control group consisted of 39 Behçet's disease patients without eye findings. Results Mean uric acid value was 4.96 ± 1.06 mg/dl in Behcet's disease patients with thrombosis whereas 4.08 ± 0.94 mg/dl in controls, indicating a significant difference ( p uric acid level was greater in Behcet's disease patients that have a thrombotic complication compared to those without thrombotic complication. Uric acid seems to play a role in the pathogenesis of thrombosis. It is concluded that the elevation of serum uric acid level in patients with anterior uveitis with Behcet's disease is not statistically significant.

The aim of this study was to validate a brief and simple measure of positive mindset in people with uveitis.MethodThis study was a cross-sectional survey of 200 people with uveitis. The Positive Mindset Index (PMI questionnaire uses six items to measure a patient’s happiness, confidence, sense of being in control, stability, motivation, and optimism. ResultsExploratory factor analysis revealed a well-fitting unidimensional factor structure (KMO = .898, with strong factor loadings (from .616 to .721 and excellent internal reliability (Cronbach’s α = .926. The PMI showed strong concurrent validity with the mental health subscale of the SF-36 (r = .789 and good construct validity relative to the physical health subscale of the SF-36 (r = .468. Excellent test-retest reliability was seen (r = .806. Patients taking 10 mg or more corticosteroid daily had significantly lower PMI scores than those on a lower dose or no dose (t (170 = 2.298, p < .023.ConclusionThe PMI has good face validity and sound psychometric properties. It is a very brief and simple measure, thus user-friendly for patients with visual impairment, as well as researchers and others using the scale.

Full Text Available The therapeutic effects of hydrogen-rich saline (HRS have been reported for a wide range of diseases mainly via selectively reducing the amount of reactive oxygen species. Oxidative stress plays an important role in the pathogenesis of uveitis and endotoxin-induced uveitis (EIU. In this study, we investigated whether HRS can mitigate EIU in rats. Sprague-Dawley rats were randomly divided into Norm group, Model group, HRS group, dexamethasone (DEX group, and rats in the latter three groups were injected with equal amount of lipopolysaccharide (LPS to induce EIU of different severities (by 1 mg/kg of LPS, or 1/8 mg/kg of LPS. Rats in HRS group were injected with HRS intraperitoneally at three different modes to purse an ameliorating effect of EIU (10 mL/kg of HRS immediately after injection of 1 mg/kg of LPS, 20 mL/kg of HRS once a day for 1 week before injection of 1 mg/kg of LPS and at 0, 0.5, 1, 2, 6, 8, 12 hours after LPS administration, or 20 mL/kg of HRS once a day for 1 week before injection of 1/8 mg/kg of LPS, and at 0, 0.5, 1, 2, 6, 8, 12, 24 hours and once a day for 3 weeks after LPS administration. Rats of DEX group were injected with 1 mL/kg of DEX solution intraperitoneally immediately after LPS administration. Rats in Norm and Model groups did not receive any treatment. All rats were examined under slit lamp microscope and graded according to the clinical signs of uveitis. Electroretinogram, quantitative analysis of protein in aqueous humor (AqH and histological examination of iris and ciliary body were also carried out. Our results showed that HRS did not obviously ameliorate the signs of uveitis under slit lamp examination and the inflammatory cells infiltration around iris and cilliary body of EIU induced by 1 mg/kg or 1/8 mg/kg of LPS (P > 0.05, while DEX significantly reduced the inflammation reflected by the above two indicators (P 0.05, while DEX had an obvious therapeutic effect (P < 0.05.

Ocorreram três surtos de dermatite ulcerativa em períodos chuvosos de abril a maio de 2013, dezembro de 2013 a fevereiro de 2014 e abril a maio deste mesmo ano. Vinte e cinco equinos do Setor de Reprodução Animal da Universidade Federal Rural do Rio de Janeiro apresentaram, na pele, lesões ulcerativas com contornos irregulares, exsudato hemorrágico, recobertas por crostas. As lesões localizavam-se sobretudo nas regiões de quartela, boleto, articulação escapulo-umeral, lábios superior e inferior, focinho, narinas, bochechas e chanfro. Sete animais foram biopsiados e o exame histopatológico revelou ulceração da epiderme e infiltrado inflamatório constituído por macrófagos e neutrófilos, delimitado por tecido de granulação subjacente. Em alguns casos, foram observados microespículos das referidas plantas (tricomas hirsutos em meio à reação inflamatória. O diagnóstico de dermatite cutânea causada pela ação traumática da planta baseou-se na presença de Mimosa spp. na pastagem, nas características e localização das lesões na pele dos equinos, nos achados histopatológicos e na recuperação após a retirada dos animais do pasto.

Full Text Available The study aims to describe the characteristics and etiologic causes of intermediate uveitis (IU patients seen by a tertiary eye center in Singapore over 8 years.This was a retrospective analysis of the clinical records of consecutive new cases of IU that presented to the uveitis subspecialty clinic from 2004-2011 at Tan Tock Seng Hospital. Data collected included demographics, clinical and laboratory findings. Diagnoses were based on standardized clinical history, ophthalmological examination and investigations.There were 66 new cases of IU, comprising 5.7% of 1168 new uveitis patients. The median age of diagnosis was 40 years (mean 39.4±15.9, with largest subgroup of the patients in the age group of 41-60 years (36.4%. The majority was Chinese (57.6%, followed by Asian Indians (18.2% and Malays (16.7%. The ethnicity distribution was dissimilar to our ethnic distribution in Singapore (p<0.001 with an increased incidence of IU in the Asian Indian population. Most were idiopathic (59.1% in etiology, followed by tuberculosis (TB (15.2%. Ocular complications developed in 21 patients (31.8%, with cystoid macular edema (CME being the commonest (28.8%. Severe vitritis occurred in 9.1% of patients, and was significantly associated with TB-associated IU (p<0.001. There was a downward trend for the incidence of the proportion of IU patients over the total uveitis patients (p = 0.021, with Spearman's rho of -0.786.Despite the downward trend, TB-associated IU was still of higher prevalence compared to less endemic areas, emphasizing the need for increased TB surveillance. A high index of suspicion for TB-associated IU is required in patients with severe vitritis. Comparisons with other countries revealed disparities in the IU etiologies, indicating possible geographical differences. Prevalence of known immune-mediated etiologies of IU is less compared to the western population. Our study also suggests a probable predisposition of the Singapore local

Several advances have been made in the diagnostic approach and therapeutic management of patients with immune-mediated uveitis over the last few decades, which have to lead to an improvement in the visual prognosis of patients. However, the use of available therapies, including steroids and immunosuppressive drugs, is still associated with limited efficacy and potentially serious side effects. Consequently, efforts have been made to develop novel therapeutic alternatives including new molecules and innovative therapeutic approaches. Herein, the authors provide an updated review of those drugs in the initial phases of evaluation for the treatment of immune-mediated uveitides as well as the latest evidence from basic research. Enhanced understanding of the pathogenic mechanisms leading to immune-mediated uveitis has led to the identification of new therapeutic targets and thus to the development of more specific drugs. In addition, considering that the eye is a semi-enclosed chamber and that local therapy has the benefit of sparing the rest of the body from potentially toxic exposure, several attempts of establishing direct ophthalmologic avenues for delivery of the established and emerging drugs have also been made. All these advances have been an unquestionable step forward in the challenging management of uveitis patients.

To investigate the effect of a single intravitreal dexamethasone implant (IVT-DI; Ozurdex; Allergan, Inc.) on visual acuity, macular thickness, and intraocular pressure (IOP) in active noninfectious uveitis. Medical records of patients with noninfectious active uveitis treated by IVT-DIs were retrospectively reviewed. Uveitis etiologies, treatment indications, best corrected visual acuity (BCVA), central retinal thickness measured by ocular coherence tomography, IOP, and systemic, local, and topical treatments were collected. Parameters were analyzed before the injection of the implant, after 1.5 ± 0.8 months and 4.4 ± 0.9 months for the BCVA, after 2 ± 1.3 months and 4.6 ± 1.3 months for the ocular coherence tomography, and after 1.3 ± 0.7 months and 4.4 ± 1 months for the IOP. We included 14 patients (20 eyes, 20 implant injections) with cystoid macular edema (78%), vasculitis (7%), choroiditis (7%), and vasculitis associated with choroiditis (7%). Before the injection, mean visual acuity was 0.4 ± 0.5 logMAR (logarithm of the minimum angle of resolution) that improved to 0.3 ± 0.5 logMAR (P = 0.0002) after 1.5 ± 0.8 months and to 0.3 ± 0.5 logMAR (P = 0.005) after 4.4 ± 0.9 months. A statistically significant decrease of macular thickness was observed both at 2 ± 1.3 months and at 4.6 ± 1.3 months after IVT-DI. Mean IOP was 16 ± 5 mmHg before injections, 18 ± 6 mmHg (P = 0.13) at 1.3 ± 0.7 months, and 15 ± 4 mmHg (P = 0.65) at 4.4 ± 1 months. By Kaplan-Meier analysis, we found that after 3.3 months, 17% of the eyes still present a BCVA amelioration ≥0.3 logMAR. In our patients with active noninfectious uveitis, injection of a first single dexamethasone implant was found to improve visual acuity and decrease macular thickness without significant increase of IOP, although the effect seems limited in time.

Full Text Available Abstract Background The relationship between intraocular pressure (IOP changes and hemodialysis has been evaluated for several decades. However, no report on an IOP rise in uveitis patients during hemodialysis has been previously documented. This report describes the case of an uveitis patient with repetitive IOP spikes associated with severe ocular pain during hemodialysis sessions, which resolved after glaucoma filtering surgery. Case presentation A 47-year-old male with diabetes and hypertension had complained of recurrent ocular pain in the left eye during hemodialysis sessions. A slit-lamp examination showed diffuse corneal epithelial edema with several white keratic precipitates and inflammatory cells (Grade 3+ in the anterior chamber of the left eye. No visible neovascularization or synechiae were visible on the iris or angle. Topical glaucoma eye-drops and intravenous mannitol before hemodialysis did not prevent subsequent painful IOP spikes in the left eye. At the end of hemodialysis, IOP averaged ~40 mmHg. After trabeculectomy with mitomycin C in the left eye, his IOP stabilized in the low-teens (range, 10–14 mmHg and no painful IOP spikes occurred during hemodialysis over the first postoperative year. Conclusion We present a case of recurrent painful IOP spikes during hemodialysis in a patient with unilateral anterior uveitis unresponsive to conventional medical treatment prior to hemodialysis. To our knowledge, this is the first case report of repetitive symptomatic IOP rise during hemodialysis in an uveitic glaucoma patient. This case highlights the importance of the awareness of the possibility that IOP may rise intolerably during hemodialysis in uveitis patients with a compromised outflow facility.

Patients with intermediate uveitis (IU) represent a heterogenous group characterized by a wide spectrum of etiologies and regional differences. Aim of the study was to analyze the characteristics of patients with IU examined in an academic center in Germany. We conducted a retrospective analysis of the clinical records of all patients with intermediate uveitis referred to the Eye Center, University of Freiburg from 2007 to 2014. Diagnosis followed the Standardization in Uveitis Nomenclature (SUN) criteria. Data analysis included: etiology of IU, demographics, complications, treatment and visual acuity. We identified 159 patients with intermediate uveitis during that period. Mean age at diagnosis was 35 years. Most are female (64%), and the mean duration of IU was 6.1 years (range 1 month - 35 years). Etiology of IU was idiopathic in 59%. Multiple sclerosis (MS) (20%) and sarcoidosis (10%) were frequent systemic causes of IU. Other etiologies including infectious diseases (tuberculosis, borreliosis) or immune-mediated conditions (eg, after vaccination) were present in 11%. The pattern of complications included macular edema (CME) (36%), cataract (24%), secondary glaucoma (7%), and epiretinal membrane formation (19%). Periphlebitis and optic neuritis were more frequent in conjunction with MS. Treatment comprised local and systemic steroids, immunosuppressive agents, biologics, and surgery. Best corrected visual acuity was better than 20/25 in 60% of the eyes after more than 10 years of follow-up. In our German academic center, most IU cases were idiopathic or associated with MS or sarcoidosis. In contrast to other countries, infectious cases were rare. Patients' overall visual prognosis is favorable even when the duration of IU has been long and and despite numerous complications.

Abatacept (ABA) has recently been proposed as second-line treatment in patients with juvenile idiopathic arthritis (JIA)-associated uveitis refractory to anti-tumor necrosis factor-α (anti-TNF) agents, but little is known about its efficacy as a first-line approach. The aim of the present study was to compare the safety and efficacy of ABA as a first-line biological agent (ABA-1) with that of ABA as a second-line treatment after 1 or more anti-TNF agents (ABA-2), in patients with severe JIA-related uveitis. In this multicenter study, we collected data on patients with severe JIA-related uveitis treated with ABA as a first-line or second-line biological agent. Changes in frequency of uveitis flares/year and ocular complications before and after ABA treatment, clinical remission, and side effects were recorded. Thirty-five patients with a mean age of 10.8 years were treated with ABA for a mean period of 19.6 months. In 4 patients, ABA administration was discontinued, owing to inefficacy on arthritis in 3 cases and allergic reaction in 1. Thirty-one patients, 14 in the ABA-1 group and 17 in the ABA-2 group, completed the 12-month followup period; of these, 17 (54.8%) had clinical remission. The mean frequency of uveitis flares decreased from 4.1 to 1.2 in the ABA-1 group (p = 0.002) and from 3.7 to 1.2 in the ABA-2 group (p = 0.004). Preexisting ocular complications improved or remained stable in all but 5 patients, all in the ABA-2 group. No significant difference was found between the efficacy of the 2 treatment modalities. ABA confirmed its good safety profile. ABA, used as first-line biological treatment or after 1 or more anti-TNF agents, induces a comparable improvement in severe refractory JIA-related uveitis.

Review and update of intraocular therapy in noninfectious uveitis.

To review new clinically relevant data regarding the intraocular treatment of noninfectious uveitis. Triamcinolone acetonide, the most commonly used intravitreal corticosteroid for treatment of uveitis and uveitic macular oedema has a limited duration of action and is associated with a high risk of corticosteroid-induced intraocular pressure (IOP) rise and cataract. Recent advances have led to the development of sustained-release corticosteroid devices using different corticosteroids such as dexamethasone and fluocinolone acetonide. Treatment options for patients who have previously exhibited corticosteroid hypertensive response have also expanded through the use of new noncorticosteroid intravitreal therapeutics such as methotrexate and antivascular endothelial growth factor (anti-VEGF) agents. Ozurdex dexamethasone implant appears to have a better safety profile, and a slightly long-lasting effect than triamcinolone acetonide. The Retisert implant allows the release of corticosteroids at a constant rate for 2.5 years, but it requires surgical placement and its use is associated with a very high risk of cataract and requirement for IOP-lowering surgery. For patients who are steroid responders, methotrexate may offer a better alternative to corticosteroid treatment than anti-VEGF agents, but controlled trials are required to confirm this.

Ocular melanin pigment has antioxidant effect against excess of dispersed light. To investigate whether it has a similar effect in ocular inflammations, we used albino and pigmented guinea pigs and measured retinal glutathione peroxidase activities and lipid peroxide levels (expressed as thiobarbituric acid reactive substances) in a model of lens induced uveitis. Although the increase in the levels of the retinal lipid peroxides were higher in the albino group (204%, p < 0.05), the decrease in the activities of glutathione peroxidase were higher in pigmented guinea pigs (26%, p < 0.005). The results of the study suggest that pigmentless animals are more sensitive to the ocular inflammations, and ocular melanin pigment may act as an endojen antioxidant in lens induced uveitis.

Full Text Available Vector-borne diseases such as Lyme borreliosis and rickettsioses have been associated with ocular inflammation. Our aim was to study patients with diagnosed uveitis to evaluate serological signs of infection or exposure to these tick-borne agents. Forty-eight patients were prospectively examined with serology together with medical records and a questionnaire concerning previous exposure, diseases, and treatments. Seven patients (14.6% showed seroconversion to Rickettsia spp. between acute and convalescent phase sera, which provides support for a positive Rickettsia diagnosis according to guidelines. The specificity was confirmed by Western blot. Additional 28 patients had stationary titres of which eight (16.6% had 1 : 256 or higher titre in the first serum, and another 13 patients were seronegative. No epidemiological risk factor or marker could be identified. For Borrelia, only three patients showed moderate IgG titres. A control group of 100 blood donors, 60 patients with rheumatic disease, and 56 patients seeking medical care were tested of which 2.0–7.1% showed low anti-Rickettsia titres and 3.0–8.3% anti-Borrelia titres. The findings are indicative for an association between infection or exposure to Rickettsia spp. and uveitis with a seropositivity among patients with recurrent uveitis in concordance with the spread of rickettsial exposure in a tick-exposed population.

To report the clinical features and outcome of patients with presumed tubercular uveitis (TBU). Retrospective analysis of patients with presumed TBU at a tertiary referral eye care centre in Singapore between 2007 and 2012 was done. Main outcome measures were failure of complete resolution of uveitis or recurrence of inflammation. Fifty three patients with mean age of 44.18 ± 15.26 years with 54.72% being males were included. 19 (35.85%) had bilateral involvement, with panuveitis and anterior uveitis being the most common presentations. 36 (67.92%) patients received antitubercular therapy (ATT), and 28 received concurrent systemic steroids. 15 (28.30%) eyes of 11 (30.55%) patients in the ATT group and 4 (21.05%) eyes of 3 (17.64%) patients in the non-ATT group had treatment failure (p value = 0.51). The use of ATT, with or without concurrent corticosteroid, may not have a statistically significant impact in improving treatment success in patients with presumed TBU.

To conduct a Bayesian analysis of a randomized clinical trial (RCT) for non-infectious uveitis using expert opinion as a subjective prior belief. A RCT was conducted to determine which antimetabolite, methotrexate or mycophenolate mofetil, is more effective as an initial corticosteroid-sparing agent for the treatment of intermediate, posterior, and pan-uveitis. Before the release of trial results, expert opinion on the relative effectiveness of these two medications was collected via online survey. Members of the American Uveitis Society executive committee were invited to provide an estimate for the relative decrease in efficacy with a 95% credible interval (CrI). A prior probability distribution was created from experts' estimates. A Bayesian analysis was performed using the constructed expert prior probability distribution and the trial's primary outcome. A total of 11 of the 12 invited uveitis specialists provided estimates. Eight of 11 experts (73%) believed mycophenolate mofetil is more effective. The group prior belief was that the odds of treatment success for patients taking mycophenolate mofetil were 1.4-fold the odds of those taking methotrexate (95% CrI 0.03-45.0). The odds of treatment success with mycophenolate mofetil compared to methotrexate was 0.4 from the RCT (95% confidence interval 0.1-1.2) and 0.7 (95% CrI 0.2-1.7) from the Bayesian analysis. A Bayesian analysis combining expert belief with the trial's result did not indicate preference for one drug. However, the wide credible interval leaves open the possibility of a substantial treatment effect. This suggests clinical equipoise necessary to allow a larger, more definitive RCT.

This study provides ophthalmologists who manage uveitic glaucoma with important information on factors that can affect the success of surgical management of this challenging disease. This study examines surgical outcomes of trabeculectomy and glaucoma device implant (GDI) surgery for uveitic glaucoma, in particular the effect of uveitis activity on surgical outcomes. Retrospective chart review at a tertiary institution. Eighty-two cases with uveitic glaucoma (54 trabeculectomies and 28 (GDI) surgeries) performed between 1 December 2006 and 30 November 2014. Associations of factors with surgical outcomes were examined using univariate and multivariate analysis. Surgical outcomes as defined in Guidelines from World Glaucoma Association. Average follow up was 26.4 ± 21.5 months. Overall qualified success rate of the trabeculectomies was not statistically different from GDI, being 67% and 75%, respectively (P = 0.60). Primary and secondary GDI operations showed similar success rates. The most common postoperative complication was hypotony (~30%). Active uveitis at the time of operation was higher in trabeculectomy compared with GDI group (35% vs. 14%). Active uveitis at the time of surgery did not significantly increase risk of failure for trabeculectomies. Recurrence of uveitis was significantly associated with surgical failure in trabeculectomy group (odds ratio 4.8, P = 0.02) but not in GDI group. Surgical success rate of GDI was not significantly different from trabeculectomy for uveitic glaucoma in this study. Regular monitoring, early and prolonged intensive treatment of ocular inflammation is important for surgical success particularly following trabeculectomy. © 2017 Royal Australian and New Zealand College of Ophthalmologists.

Behçet's disease (BD) involves multisystem vasculitis of unknown origin. Ocular manifestations of BD mostly include bilateral panuveitis and retinal vasculitis, which are very challenging to treat. Interferon alfa-2a (IFN) has been recently introduced for treating refractory Behçet uveitis, mainly in Germany and Turkey. Nonetheless, there is so far no consensus about the ideal treatment regimen of IFN for Behçet uveitis. We report our experience of IFN treatment in five Korean BD patients with refractory uveitis. All patients complained of oral ulcers; one patient had a positive pathergy test and 2 showed the presence of HLA-B51. Immunosuppressive agents used prior to IFN treatment included cyclosporine and methotrexate. The IFN treatment was commenced with a dose of 6-9 MIU/day for 7 days, adjusted according to individual ocular manifestations, tapered down to 3 MIU three times in a week, and then discontinued. All patients showed positive response to IFN treatment; 50% of them showed complete response without additional major ocular inflammation during the follow-up period. Other BD symptoms also improved after IFN treatment in most cases. After treatment, the relapse rate and the required dose of oral corticosteroid were decreased in most cases, showing a significant steroid-sparing effect. However, the visual acuity was not improved in most cases due to irreversible macular sequelae. Despite the small sample size of this study, we suggest that, in Korean patients, IFN is an effective treatment modality for BD uveitis as was observed in German and Turkish patients.

Laser flare photometry (LFP) is an objective and quantitative method to measure intraocular inflammation. The LFP technology was developed in Japan and has been commercially available since 1990. The aim of this work was to review the application of LFP in uveitis practice in Europe compared to Japan where the technology was born. We reviewed PubMed articles published on LFP and uveitis. Although LFP has been largely integrated in routine uveitis practice in Europe, it has been comparatively neglected in Japan and still has not received FDA approval in the USA. As LFP is the only method that provides a precise measure of intraocular inflammation, it should be used as a gold standard in uveitis centres worldwide.

Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease, defined by the association of idiopathic acute TINU. The aim of our work was to determine the characteristics of adult TINU syndrome in France, and to assess factors (including treatment) influencing medium-term prognosis.We conducted a nationwide study including 20 French hospitals. Clinical, laboratory, and renal histopathologic data of 41 biopsy-proven TINU syndromes were retrospectively collected. The patients were diagnosed between January 1, 1999 and December 1, 2015.Twenty-five females and 16 males were included (F/M ratio: 1.6:1). The median age at disease onset was 46.8 years (range 16.8-77.4) with a median serum creatinine level at 207 μmol/L (range 100-1687) and a median estimated glomerular filtration rate (eGFR) at 27 mL/min per 1.73 m (range 2-73). Twenty-nine patients (71%) had a bilateral anterior uveitis and 24 (59%) had deterioration in general health at presentation. Moderate proteinuria was found in 32 patients (78%) (median proteinuria 0.52 g/24 h; range 0.10-2.10), aseptic leukocyturia in 25/36 patients (70%). The evaluation of renal biopsies revealed 41 patients (100%) with an acute tubulointerstitial nephritis, 19/39 patients (49%) with light to moderate fibrosis and 5 patients (12%) with an acute tubular necrosis. Thirty-six patients (88%) were treated with oral corticosteroids. After 1 year of follow-up, the median eGFR was 76 mL/min per 1.73 m (range 17-119) and 32% of the patients suffered from moderate to severe chronic kidney disease.

To re-evaluate the ability of methotrexate (MTX) to prevent the onset of uveitis in Russian children with juvenile idiopathic arthritis (JIA). The clinical charts for all consecutive patients who received a stable management for at least 2 years with or without MTX were reviewed. Patients who were given systemic medications other than MTX (except NSAID) and patients with systemic arthritis, rheumatoid factor-positive arthritis, or enthesitis-related arthritis were excluded. Each patient was examined after at least a 2-year follow-up period after the first visit to establish whether uveitis had occurred. A total of 281 patients with a median disease duration of 3.8 years were included. 191 patients (68%) were treated with MTX. During the observation period, 64 patients (22.8%) developed uveitis, a median of 1.6 year after disease onset. The frequency of uveitis was lower in MTX-treated than in MTX-untreated patients (11.5% vs. 46.7%, respectively, OR=6.7 (95%CI:3.7-12.3), p=0.0000001). Survival analysis confirmed that patients treated with MTX had a lower probability of developing uveitis (HR=4.35, p=0.000001). In subgroup analysis it was shown that MTX was more preventive in boys than in girls, and in patients with JIA onset age of over 5 years compared to those with disease onset less than 5 years. The data of survival analysis of MTX prevention has shown that benefits do not depend on the number of active joints and ANA status. MTX therapy may prevent the onset of uveitis in children with JIA. Further randomised controlled trials are required to confirm our results.

Full Text Available Corticosteroids along with other immunomodulatory therapies remain as the mainstay of treatment tor all patients with noninfectious uveitis (NIU. However, the systemic side effects associated with the long-term use of these drugs has encouraged the development of new therapeutic agents in recent times. This review article discusses upcoming therapeutic agents and drug delivery systems that are currently being used to treat patients with NIU. These agents mediate their actions by blocking specific pathways involved in the inflammatory process. Agents discussed in this review include full or recombinant monoclonal antibodies against interleukins such as IL-17 (secukinumab, IL-l (gevokizumab, and IL-6 (tocilizumab and sarilumab, antibody fragments against inflammatory cytokines such as TNF-α (ESBA 105 and T-cell inhibitors such as fusion proteins (abatacept, and next generation calcineurin inhibitors (voclosporin. In addition, administration of immune modulatory therapies using methods such as iontophoresis (EGP-437 and intravitreal injection (sirolimus for the treatment of NIU' uveitis has also been discussed.

Un año mas tarde, en marzo de 2002, una segunda proliferación, conformada por la misma especie, se reportó cerca de Cabo Corrientes con una concentración de 1.6 x 10(6 céls l -1 . Ambos casos estuvieron relacionados con la presencia de bajas temperaturas en la superficie del mar y no estuvieron asociadas con fenómenos de intoxicación y mortalidadFrom April 26th to May 15th 2001, a large algae bloom was observed off Tumaco Bay on the Pacific coast of Colombia. This was the first harmful algae bloom (HAB reported in the region, and reached Gorgona Island, about 120 km north. Ayear later, starting March 2002, an offshore HAB developed from Cabo Corrientes North to Solano Bay. The typical abundance during the blooms reached 7.5 x 10(6 cells l-1 for the 2001 event and 1.6 x 10(6 cells l-1 for the 2002 event. During both events, low temperature and high salinity were recorded. Typical measurements in the area are 27-27.5°C and 30-31.5 psu. Values observed during the two events were 24-24.6°C and 33-34 psu; 3°C below normal and more than 2.5 psu above average values. These conditions are indicative of local upwelling processes at the time of the events. On both occasions, cells corresponding to the Alexandrium catenella/fundeyense/tamarense complex represented 99-100% of the biomass. It was difficult to differentiate the cells from A. catenella, but the presence of short chains of only 4 cells (single cells represented most of the biomass was suggestive of A. tamarense.

Full Text Available Human uveitis is a type of T cell-mediated autoimmune disease that often shows relapse-remitting courses affecting multiple biological processes. As a cytoplasmic process, autophagy has been seen as an adaptive response to cell death and survival, yet the link between autophagy and T cell-mediated autoimmunity is not certain. In this study, based on the differentially expressed genes (GSE19652 between the recurrent versus monophasic T cell lines, whose adoptive transfer to susceptible animals may result in respective recurrent or monophasic uveitis, we proposed grouping annotations on a subcellular layered interactome framework to analyze the specific bioprocesses that are linked to the recurrence of T cell autoimmunity. That is, the subcellular layered interactome was established by the Cytoscape and Cerebral plugin based on differential expression, global interactome, and subcellular localization information. Then, the layered interactomes were grouping annotated by the ClueGO plugin based on Gene Ontology and Kyoto Encyclopedia of Genes and Genomes databases. The analysis showed that significant bioprocesses with autophagy were orchestrated in the cytoplasmic layered interactome and that mTOR may have a regulatory role in it. Furthermore, by setting up recurrent and monophasic uveitis in Lewis rats, we confirmed by transmission electron microscopy that, in comparison to the monophasic disease, recurrent uveitis in vivo showed significantly increased autophagy activity and extended lymphocyte infiltration to the affected retina. In summary, our framework methodology is a useful tool to disclose specific bioprocesses and molecular targets that can be attributed to a certain disease. Our results indicated that targeted inhibition of autophagy pathways may perturb the recurrence of uveitis.

Syphilitic chorioretinitis should be included in differential diagnosis of any form of ocular inflammation. A significantly higher proportion of human immunodeficiency virus (HIV)-positive patients with ocular syphilis as compared to HIV-negative cases have been reported in published studies. However, the clinical signs and symptoms are more insidious in HIV-negative patients who are easily misdiagnosed. We report a series of cases of ocular syphilis and describe the clinical manifestations and treatment outcomes of syphilitic chorioretinitis in HIV-negative patients in China.This was a retrospective case series study. The clinical records of patients with syphilis chorioretinitis were reviewed. Demographic information and findings of fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), and spectral domain optical coherence tomography (SD-OCT) were analyzed. All patients received the standard treatment. Ophthalmology examination and laboratory evaluation were repeated every 3 months. All changes were recorded. The treatment was considered successful if the patients had no inflammation in both eyes and rapid plasma reagin titer was negative after therapy.The study examined 41 eyes of 28 HIV-negative patients. The main complaints were blurry vision, floaters, and visual field defect. Twenty-seven eyes presented with panuveitis, and all had posterior involvement, including uveitis, vasculitis, chorioretinitis, and optic neuritis. The most common manifestations were uveitis and retinal vasculitis. Disc hyperfluorescence and persistent dark spots were the most common findings on FFA and ICGA. The ill-defined inner segment/outer segment junction was the most frequent manifestation on SD-OCT. Patients were diagnosed with syphilitic uveitis based on positive serological tests. Best-corrected visual acuity (BCVA) was improved in 34 eyes after treatment. Eleven patients were misdiagnosed before serological tests were performed. The delay in treatment

The subretinal fibrosis and uveitis (SFU) syndrome is a rare multifocal posterior uveitis characterized by progressive subretinal fibrosis and significant visual loss. Slit-lamp examination, dilated fundoscopy, fluorescein angiography, Spectral Domain-Optical Coherence Tomography (SD-OCT) and laboratory testing were employed. A 52-year-old male presented with bilateral (best-corrected visual acuity: 2/10) visual loss. Clinical examination revealed bilateral anterior uveitis with posterior synechiae and posterior uveitis. Medical workup revealed no pathologic findings. Treatment included 1 gr intravenous prednisone followed by oral prednisone, immunosuppresive therapy and three ranibizumab injections in the right eye with no improvement. One year later, there was significant subretinal fibrosis. In the second year follow-up, the picture was slightly worse, with persisting bilateral macular edema and fibrosis. This is the first SFU syndrome report monitored with SD-OCT. This novel imaging modality can localize the lesion level, guide the therapeutic approach and may prove helpful in assessing disease prognosis.

A pilot study to evaluate the use of intravitreal methotrexate (MTX) for the treatment of uveitis and uveitic cystoid macular edema (CME). Prospective, consecutive, interventional case series. Fifteen eyes of 15 patients with a unilateral exacerbation of noninfectious intermediate, posterior uveitis, or panuveitis and/or CME such that visual acuity (VA) was 20/40 or worse, together with a history of increased intraocular pressure (IOP) in response to corticosteroid administration. Intravitreal injection of 400 microg in 0.1 ml MTX. The primary outcome measure was VA (using the Early Treatment Diabetic Retinopathy Study chart). Other outcome measures included ocular inflammation scores, time to relapse, levels of systemic corticosteroid and immunosuppressive therapy, and ocular coherence tomography. Potential complications of intravitreal MTX injection, including cataract progression, vitreous hemorrhage, retinal detachment, and corneal epitheliopathy, were assessed. VA improved at all time points and was statistically significant at the 3- and 6-month follow-up examinations. The mean visual improvement was 4 lines at 3 months and 4.5 lines at 6 months, with no statistical difference between the best VA obtained after MTX injection and after previous corticosteroid treatment, including intravitreal triamcinolone acetate injection. Five patients relapsed after a median of 4 months; a similar improvement was seen after re-injection. Ocular inflammation scores improved at all time points, and systemic immunosuppressive medication was reduced in 3 of 7 patients taking this at the start of the trial. In patients with uveitis and uveitic CME, intravitreal MTX can improve VA and reduce CME and, in some patients, allows the reduction of immunosuppressive therapy. Relapse occurs at a median of 4 months in some patients, but reinjection has similar efficacy.

Management of patients with severe immune-mediated uveitis requires the use of immunosuppressive drugs in selected cases. This may be especially challenging in certain patients with concomitant conditions, which could increase the risk of side effects or modify guidelines for the use of such drugs. Therapeutic decision-making and management may be of particular difficulty in pregnancy as well as in patients with associated malignancies unrelated to a specific ophthalmic inflammatory condition. The main aim of this review is to provide an updated comprehensive practical guide for practitioners regarding the therapeutic decision-making and management of patients with severe immune-mediated uveitis in the context of pregnancy and malignancies. Management of patients with immune-mediated uveitis requiring immunosuppressive/immunomodulatory drugs might be particularly complicated by other conditions affecting their health and immune status. Clinicians should take into account such conditions, which might influence treatment response and the clinical outcome of these patients.

Intravitreal injection therapy in the treatment of noninfectious uveitis.

Uveitis is responsible for 5-20% of legal blindness in the United States and in Europe. In noninfectious uveitis, the most frequent uveitic complication that endangers sight is cystoid macular edema. Clinical characteristics, inflammation grading and visual acuity determine the choice of the correct therapy for each patient. We can utilize drugs either alone or in combination using different dosages and routes of administration. Intravitreal injection directly into the vitreous cavity leads to rapid therapeutic drug concentration in the retinal tissue and reduces systemic side effects. Intravitreally injected triamcinolone acetonide is the most powerful drug for the treatment of cystoid macular edema related to intraocular inflammation, but it also causes the most frequent and serious side effects. Due to the numerous side effects associated with the use of corticosteroids, there is a need to identify other anti-inflammatory agents with a better safety profile. Recent studies have demonstrated that intravitreal immunosuppressant injections of methotrexate or anti-VEGF agents may lead to fewer intraocular side effects, but also have a lower therapeutic activity for the reduction of macular edema. At present, intraocular anti-TNF-α drugs do not show promising results. As regards nonsteroidal anti-inflammatory drugs, further data are necessary to fully understand their efficacy and potential side effects. Copyright © 2012 S. Karger AG, Basel.

Quantitative monitoring of ocular inflammation in small animal models provides an objective metric to assess uveitis progression and/or therapeutic effects. We present a new application of optical coherence tomography (OCT) and OCT-based microangiography (OMAG) to a rat model of acute anterior uveitis induced by intravitreal injection of a killed mycobacterial extract. OCT/OMAG is used to provide noninvasive three-dimensional imaging of the anterior segment of the eyes prior to injection (baseline) and two days post-injection (peak inflammation) in rats with and without steroid treatments. OCT imaging identifies characteristic structural and vascular changes in the anterior segment of the inflamed animals when compared to baseline images. Characteristics of inflammation identified include anterior chamber cells, corneal edema, pupillary membranes, and iris vasodilation. In contrast, no significant difference from the control is observed for the steroid-treated eye. These findings are compared with the histology assessment of the same eyes. In addition, quantitative measurements of central corneal thickness and iris vessel diameter are determined. This pilot study demonstrates that OCT-based microangiography promises to be a useful tool for the assessment and management of uveitis in vivo.

The aim of the present study was to evaluate the effect of conditioned medium from human uterine cervical stem cells (CM-hUCESCs) in uveitis. To do that, uveitis was induced in rats after footpad injection of Escherichia coli lipopolysaccaride (LPS). Human retinal pigment epithelial (ARPE-19) cells after LPS challenge were used to test anti-inflammatory effect of CM-hUCESCs 'ìn vitro'. Real-time PCR was used to evaluate mRNA expression levels of the pro-inflammatory cytokines interkeukin-6, interkeukin-8, macrophage inflammatory protein-1 alpha, tumor necrosis factor alpha, and the anti-inflammatory interkeukin-10. Leucocytes from aqueous humor (AqH) were quantified in a Neubauer chamber, and eye histopathological analysis was done with hematoxylin-eosin staining. Additionally, using a human cytokine antibody array we evaluated CM-hUCESCs to determine mediating proteins. Results showed that administration of CM-hUCESCs significantly reduced LPS-induced pro-inflammatory cytokines both 'in vitro' and 'in vivo', and decreased leucocytes in AqH and ocular tissues. High levels of cytokines with anti-inflammatory effects were found in CM-hUCESCs, suggesting a possible role of these factors in reducing intraocular inflammation. In summary, treatment with CM-hUCESCs significantly reduces inflammation in uveitis. Our data indicate that CM-hUCESCs could be regarded as a potential therapeutic agent for patients suffering from ocular inflammation. Copyright © 2016 Elsevier Ltd. All rights reserved.

Treatment of adult, noninfectious uveitis remains a challenge for ophthalmologists around the world. The disease accounts for almost 10% of preventable blindness in the US and can be idiopathic or associated with infectious and systemic disorders. Strong evidence is still emerging to indicate that pharmacologic strategies presently used in rheumatologic or autoimmune disease may be translated to the treatment of intraocular inflammation. Corticosteroid monotherapy is widely regarded as wholly inappropriate, due to the unfavorable risk/benefit profile and poor long-term outcomes. Treatment plans have shifted away from low-dose, chronic corticosteroid therapy for maintenance, towards medium- to high-dose therapy for acute inflammation, followed immediately by initiation of immunomodulatory therapy. These therapies follow the 'stepladder approach', whereby least to more aggressive therapies are trialed to induce remission of inflammation, eventually without corticosteroids of any form (topical, local and systemic). 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 of ocular inflammation. Part I covers classic immunomodulation and latest information on corticosteroid therapy. The hazard of chronic corticosteroid use for 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.

Full Text Available RESUMO Tuberculose é uma doença infecciosa causada pelo Mycobacterium tuberculosis, também conhecido como bacilo de Koch. O principal sítio de acometimento é o pulmonar, porém o bacilo pode disseminar-se por via linfo-hematogênica para outros órgãos, dentre eles o olho. A incidência de tuberculose ocular é de 1 a 2% dos casos extrapulmonares. Os autores apresentam um caso clínico de um paciente do sexo feminino de 28 anos que procura atendimento médico devido à redução da acuidade visual em olho esquerdo há 7 dias. Apresentava a melhor acuidade visual corrigida no olho acometido de 20/200 e no olho contralateral de 20/20. Na fundoscopia era evidenciado um granuloma em área macular do olho esquerdo, com edema e hemorragia intrarretiniana adjacente. Após investigação diagnóstica, a paciente foi tratada com esquema antibiótico para tuberculose durante 6 meses, obtendo regressão do granuloma e melhora da acuidade visual deste olho para 20/50.

We evaluated the efficacy of lycopene, a dietary carotenoid and potent antioxidant, against ocular inflammation and oxidative stress in an experimental uveitis model. Endotoxin-induced uveitis (EIU) was induced in Sprague-Dawley rats by a single subcutaneous injection of 200 μg lipopolysaccharide (LPS). Induction of EIU was preceded by daily intraperitoneal injection of 10 mg/kg lycopene for three consecutive days (Lycopene + LPS group) or equivolume vehicle (Vehicle + LPS group). A positive control group received 1 mg/kg dexamethasone pretreatment (DEX + LPS), and a negative control group received daily vehicle injection but no LPS (Vehicle Control). Twenty-four hours after LPS or final vehicle administration, eyes were enucleated, and aqueous humor was collected for measurement of the number of infiltrating cells, total protein concentration, and levels of nitric oxide (NO), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and oxidative stress markers. Inflammatory response severity was compared among groups clinically and histopathologically. Infiltrating cell number, total protein concentration, and NO, TNF-α, and IL-6 levels were significantly elevated in the aqueous humor of Vehicle + LPS group rats compared to Vehicle Controls. Compared to the Vehicle + LPS group, lycopene pretreatment significantly reduced aqueous humor concentrations of oxidative stress markers, NO (0.29 ± 0.1 μM vs. 0.19 ± 0.1 μM, p=0.003), TNF-α (71.0 ± 22.3 ng/ml vs. 50.1 ± 2.1 ng/ml, p=0.043), and IL-6 (121.6 ± 3.0 pg/ml vs. 111.1 ± 5.6 pg/ml, p=0.008). Inflammatory score was also reduced (2.0 ± 0.0 vs. 0.4 ± 0.5, p=0.001). Lycopene reduced the infiltrating cell count and protein concentration, but differences did not reach significance. Most lycopene effects were equivalent to dexamethasone. Lycopene may aid in the clinical management of uveitis by suppressing inflammation and oxidative stress.

To describe aqueocentesis cytopathology results from dogs and cats presenting for uveitis investigation and to determine whether this is a useful and safe procedure. Dogs and cats presenting for investigation of anterior uveitis (April 2008-December 2013). Aqueous was collected via limbal entry under sedation/general anesthesia, for cytopathology and occasionally bacterial culture or polymerase chain reaction (PCR) testing. Further workup included blood testing (hematology, biochemistry, and serology), diagnostic imaging, nonocular cytopathology, and available histopathology. Fifty-six dogs and 39 cats were included in the study. An aqueous cytopathologic diagnosis of lymphoma (or discrete cell neoplasia) was made in six dogs and seven cats, and a diagnosis of large cell carcinoma made in one dog. This diagnosis of lymphoma was confirmed by ocular histopathology in two dogs and one cat; nonocular cytopathology corroborated lymphoma in another three dogs and five cats. Lymphoma was not evident on aqueous cytopathology but confirmed on nonocular histopathology in two dogs and by cytopathology in one cat. Additionally, aqueous cytopathology in three cats suggested, but was not considered diagnostic of, lymphoma; one of these cats had a confirmatory diagnosis of lymphoma on subsequent clinical investigation. Aqueous humor cytopathology alone was not diagnostic in non-neoplastic anterior uveitis cases, but supplemented the clinical picture with other systemic diagnostic tests. No clinically important complications were reported in association with aqueocentesis. Aqueocentesis is performed readily with minimal risk. The results were primarily useful in aiding a diagnosis of lymphoma in both dogs and cats. © 2014 American College of Veterinary Ophthalmologists.

To study the amelioration of ocular inflammation in endotoxin-induced uveitis (EIU) in rats by benfotiamine, a lipid-soluble analogue of thiamine. EIU in Lewis rats was induced by subcutaneous injection of lipopolysaccharide (LPS) followed by treatment with benfotiamine. The rats were killed 3 or 24 hours after LPS injection, eyes were enucleated, aqueous humor (AqH) was collected, and the number of infiltrating cells, protein concentration, and inflammatory marker levels were determined. Immunohistochemical analysis of eye sections was performed to determine the expression of inducible-nitric oxide synthase (iNOS), cyclooxygenase (Cox)-2, protein kinase C (PKC), and transcription factor NF-kappaB. Infiltrating leukocytes, protein concentrations, and inflammatory cytokines and chemokines were significantly elevated in the AqH of EIU rats compared with control rats, and benfotiamine treatment suppressed these increases. Similarly increased expression of inflammatory markers iNOS and Cox-2 in ciliary body and retinal wall was also significantly inhibited by benfotiamine. The increased phosphorylation of PKC and the activation of NF-kappaB in the ciliary body and in the retinal wall of EIU rat eyes were suppressed by benfotiamine. These results suggest that benfotiamine suppresses oxidative stress-induced NF-kappaB-dependent inflammatory signaling leading to uveitis. Therefore, benfotiamine could be used as a novel therapeutic agent for the treatment of ocular inflammation, especially uveitis.

To investigate the anti-inflammatory effect of an aqueous whole plant extract of Heliotropium indicum (HIE) on endotoxin-induced uveitis in New Zealand white rabbits. Clinical signs of uveitis including flares, iris hyperemia and miosis, were sought for and scored in 1.0 mg/kg lipopolysaccharide (LPS) -induced uveitic rabbits treated orally with HIE (30-300 mg/kg), prednisolone (30 mg/kg), or normal saline (10 mL/kg). The number of polymorphonuclear neutrophils infiltrating, the protein concentration, as well as levels of tumor necrosis factor-α (TNF-α), prostaglandin E2 (PGE2), and monocyte chemmoattrant protein-1 (MCP-1) in the aqueous humor after the various treatments were also determined. A histopathological study of the anterior uveal was performed. The extract and prednisolone-treatment significantly reduced (P≤0.001) both the clinical scores of inflammation (1.0-1.8 compared to 4.40±0.40 in the normal saline-treated rabbits) and inflammatory cells infiltration. The level of protein, and the concentrations of TNF-α, PGE2 and MCP-1 in the aqueous humor were also significantly reduced (P≤0.001). Histopathological studies showed normal uveal morphology in the HIE and prednisolone-treated rabbits while normal saline-treated rabbits showed marked infiltration of inflammatory cells. The HIE exhibits anti-inflammatory effect on LPS-induced uveitis possibly by reducing the production of pro-inflammatory mediators.
