Cost-Effectiveness Analysis of Fluocinolone Acetonide Intravitreal (FAI) Implant for Chronic Noninfectious Uveitis Affecting the Posterior Segment of the Eye (NIU-PS) in China. Ophthalmol Ther 2024; 13:1757-1772. [PMID: 38676875 PMCID: PMC11109073 DOI: 10.1007/s40123-024-00939-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2024] [Accepted: 03/22/2024] [Indexed: 04/29/2024] Open
Abstract
INTRODUCTION Chronic non-infectious uveitis affecting the posterior segment (NIU-PS), which can be recurrent and persistent for numerous years, mainly affects people of working age and significantly increases the risk of visual impairment. This study aimed to investigate the cost-effectiveness of fluocinolone acetonide intravitreal (FAI) implant in the treatment of patients with chronic NIU-PS from the Chinese healthcare perspective. METHODS A Markov model with a 2-week cycle was constructed from the perspective of the Chinese healthcare system over a lifetime time horizon. The model consists of four health states: on-treatment, treatment failure, blindness, and death. The outcomes for effectiveness were based on the Chinese real-world study (RWS). Utilities and mortality rates were derived from published literature and standard sources. Costs were determined from the MENET website, prices of medical service items at local providers, published literature, and expert surveys. Outcomes were measured in quality-adjusted life years (QALYs). Sensitivity analyses were performed to account for the impact of uncertainty. RESULTS It was estimated that in the base case, the FAI implant provided 0.43 incremental QALYs compared with the limited current practice (LCP) at an additional cost of $7503.72 (¥50,575.05), resulting in an incremental cost-effectiveness ratio (ICER) of $17,373.49 (¥117,097.33) per QALY gained. Parameters related to utility emerged as the primary influencers on the outcomes. In probabilistic sensitivity analysis (PSA), considering the willingness-to-pay (WTP) threshold of $19,072 (¥128,547) and $38,145 (¥257,094), the FAI implant had 67.70% and 99.50% probability of being cost-effective, respectively. As demonstrated in the scenario analysis, if the FAI implant aligns its price reduction with the average rate from the 2023 negotiation of the National Reimbursement Drug List (NRDL), it would result in lower costs and represent an absolute advantage. CONCLUSIONS The FAI implant, which can effectively reduce the recurrence rate and maintain the incremental costs within the WTP limit, is likely to be cost-effective in treating chronic NIU-PS in China.

Subconjunctival injection of rapamycin-loaded polymeric microparticles for effective suppression of noninfectious uveitis in rats. Int J Pharm 2024; 657:124178.

Abstract
Noninfective uveitis is a major cause of vision impairment, and corticosteroid medication is a mainstay clinical strategy that causes severe side effects. Rapamycin (RAPA), a potent immunomodulator, is a promising treatment for noninfective uveitis. However, because high and frequent dosages are required, it is a great challenge to implement its clinical translation for noninfective uveitis therapy owing to its serious toxicity. In the present study, we engineered an injectable microparticulate drug delivery system based on biodegradable block polymers (i.e., polycaprolactone-poly (ethylene glycol)-polycaprolactone, PCEC) for efficient ocular delivery of RAPA via a subconjunctival injection route and investigated its therapeutic efficacy in an experimental autoimmune uveitis (EAU) rat model. RAPA-PCEC microparticles were fabricated using the emulsion-evaporation method and thoroughly characterized using scanning electron microscopy, fourier transform infrared spectroscopy, X-ray diffraction, and differential scanning calorimetry. The formed microparticles exhibited slow in vitro degradation over 28 days, and provided both in vitro and in vivo sustained release of RAPA over 4 weeks. Additionally, a single subconjunctival injection of PCEC microparticles resulted in high ocular tolerance. More importantly, subconjunctival injection of RAPA-PCEC microparticles significantly attenuated the clinical signs of EAU in a dose-dependent manner by reducing inflammatory cell infiltration (i.e., CD45+ cells and Th17 cells) and inhibiting microglial activation. Overall, this injectable microparticulate system may be promising vehicle for intraocular delivery of RAPA for the treatment of noninfective uveitis.

Abstract
BACKGROUND Anterior uveitis is the most common anatomical type of uveitis. Patients with noninfectious anterior uveitis may develop various ocular complications and eventually visual impairment. Appropriately differentiating the etiologies can help clinicians to predict the outcome, arrange clinical follow-up, and decide the treatment or prevention strategy. Adequate treatment and effective prevention strategies can reduce the frequency of recurrence and the risk of developing complications. Human leukocyte antigen (HLA)-B27 is the most common positive finding in patients with noninfectious AAU in many countries including Taiwan. PURPOSE To report a consensus from experienced uveitis specialists and rheumatologists was made in Taiwan. METHODS A panel of nine ophthalmologists from nine different referral centers with expertise in the management of uveitis and an experienced rheumatologist was held on January 16, 2022. A comprehensive literature review was performed. Differential diagnoses for etiologies, general treatments, and prevention strategies were discussed. Each statement in the consensus was made only if more than 70% of the experts agreed. RESULTS A flow chart and seven statements regarding the differential diagnoses for etiologies, treatments and preventions, and co-management with rheumatologists were included in the consensus. CONCLUSIONS This article discusses the general diagnosis, treatment, and prevention of noninfectious acute anterior uveitis, with or without HLA-B27, in adults for general ophthalmologists to improve overall outcomes of these patients.

Abstract
PURPOSE To evaluate the efficacy and safety of switching from adalimumab originator (Humira, AbbVie) to SB5, adalimumab biosimilar (Adalloce, Samsung Bioepis) in patients with noninfectious uveitis (NIU). METHODS Fifteen patients (29 eyes) with NIU who were switched from adalimumab originator to SB5 and followed up for 6 months or longer were retrospectively included. Data consisted of best-corrected visual acuity (BCVA, logMAR), intraocular pressure (IOP, mmHg), anterior chamber (AC) cell grade, anterior vitreous (AV) cell grade, vitreous haze grade, central macular thickness (CMT, μm), and macular volume (MV, mm3) at pre-switching, 2, 4, and 6 months post-switching. RESULTS There were no significant differences in BCVA, AC and AV cell grades, and vitreous haze grades at 2, 4, and 6 months post- compared with pre-switching, and no significant differences in CMT and MV at 2 and 6 months post-switching. CMT and MV decreased from 260.55 ± 67.44 μm and 8.37 ± 1.14 mm3 at pre-switching to 244.14 ± 60.31 μm (p = 0.032) and 8.11 ± 1.20 mm3 (p = 0.027) at 4 months post-switching, respectively. There was no recurrence of uveitis, as defined by AC cell grade, vitreous haze, or BCVA. Four patients (27%) were switched back to adalimumab originator after a mean of 9 weeks, due to discomfort during the injection (three patients) and technical difficulty with the new injection device (one patient). No other adverse events occurred after switching to SB5. CONCLUSION Switching from adalimumab originator to SB5 for NIU does not result in clinically significant differences in treatment efficacy and safety.

Abstract
Chagas disease (CD), caused by the protozoan parasite Trypanosoma cruzi, is a neglected disease affecting around 6 million people. About 30% of CD patients develop chronic Chagas disease cardiomyopathy (CCC), an inflammatory cardiomyopathy that occurs decades after the initial infection, while most infected patients (60%) remain asymptomatic in the so-called indeterminate form (IF). Death results from heart failure or arrhythmia in a subset of CCC patients. Myocardial fibrosis, inflammation, and mitochondrial dysfunction are involved in the arrhythmia substrate and triggering events. Survival in CCC is worse than in other cardiomyopathies, which may be linked to a Th1-T cell rich myocarditis with abundant interferon (IFN)-γ and tumor necrosis factor (TNF)-α, selectively lower levels of mitochondrial energy metabolism enzymes in the heart, and reduced levels of high-energy phosphate, indicating poor adenosine triphosphate (ATP) production. IFN-γ and TNF-α signaling, which are constitutively upregulated in CD patients, negatively affect mitochondrial function in cardiomyocytes, recapitulating findings in CCC heart tissue. Genetic studies such as whole-exome sequencing (WES) in nuclear families with multiple CCC/IF cases has disclosed rare heterozygous pathogenic variants in mitochondrial and inflammatory genes segregating in CCC cases. In this minireview, we summarized studies showing how IFN-γ and TNF-α affect cell energy generation, mitochondrial health, and redox homeostasis in cardiomyocytes, in addition to human CD and mitochondria. We hypothesize that cytokine-induced mitochondrial dysfunction in genetically predisposed patients may be the underlying cause of CCC severity and we believe this mechanism may have a bearing on other inflammatory cardiomyopathies.

Abstract
Purpose To evaluate the immune regulatory effect of human cord blood myeloid-derived suppressor cells (MDSCs) in experimental autoimmune uveitis (EAU) models. Methods MDSCs (1 × 106) or PBS were injected into established C57BL/6 EAU mice via the subconjunctival route on days 0 and 7. The severity of intraocular inflammation was evaluated for up to 3 weeks. Tissue injury and inflammation were analyzed using immunolabelled staining, real-time PCR, and ELISA. In addition, immune cells in draining lymph nodes (LNs) were quantified using flow cytometry. Results After 21 days, the clinical scores and histopathological grades of EAU were lower in the MDSCs group compared with the PBS group. Local administration of MDSCs suppressed the oxidative stress and the expression of TNF-α and IL-1β in the retinal tissues. In addition, it inhibited the activation of pathogenic T helper 1 (Th1) and Th17 cells in draining LNs. MDSCs increased the frequency of CD25+ Foxp3+ regulatory T cells and the mRNA expression of IL-10, as an immune modulator. Conclusions MDSCs suppressed inflammation and oxidative stress in the retina and inhibited pathogenic T cells in the LNs in EAU. Therefore, ocular administration of MDSCs has therapeutic potential for uveitis.

Abstract
Objectives Non-infectious uveitis is often secondary to systemic autoimmune diseases, with Behçet's disease (BD) and Vogt-Koyanagi-Harada disease (VKHD) as the two most common causes. Uveitis in BD and VKHD can show similar clinical manifestations, but the underlying immunopathogenesis remains unclear. Methods To understand immune landscapes in inflammatory eye tissues, we performed single-cell RNA paired with T cell receptor (TCR) sequencing of immune cell infiltrates in aqueous humour from six patients with BD (N = 3) and VKHD (N = 3) uveitis patients. Results Although T cells strongly infiltrated in both types of autoimmune uveitis, myeloid cells only significantly presented in BD uveitis but not in VKHD uveitis. Conversely, VKHD uveitis but not BD uveitis showed an overwhelming dominance by CD4+ T cells (> 80%) within the T cell population due to expansion of CD4+ T cell clusters with effector memory (Tem) phenotypes. Correspondingly, VKHD uveitis demonstrated a selective expansion of CD4+ T cell clones which were enriched in pro-inflammatory Granzyme H+ CD4+ Tem cluster and showed TCR and Th1 pathway activation. In contrast, BD uveitis showed a preferential expansion of CD8+ T cell clones in pro-inflammatory Granzyme H+ CD8+ Tem cluster, and pathway activation for cytoskeleton remodelling, cellular adhesion and cytotoxicity. Conclusion Single-cell analyses of ocular tissues reveal distinct landscapes of immune cell infiltration and T-cell clonal expansions between VKHD and BD uveitis. Preferential involvements of pro-inflammatory CD4+ Th1 cells in VKHD and cytotoxic CD8+ T cells in BD suggest a difference in disease immunopathogenesis and can guide precision disease management.

Abstract
Autoimmune uveitis is a non-infectious, inflammatory intraocular disease that affects the uveal and adjacent tissues. It frequently causes varying degrees of visual loss. Evidence for the strong association between activated γδ T cells and the development of autoimmune uveitis is growing. The innate and adaptive immune response are connected in the early phases by the γδ T cells that contain the γ and δ chains. γδ T cells can identify antigens in a manner that is not constrained by the MHC. When activated by various pathways, γδ T cells can not only secrete pro-inflammatory factors early on (such as IL-17), but they can also promote Th17 cells responses, which ultimately exacerbates autoimmune uveitis. Therefore, we review the mechanisms by which γδ T cells affect autoimmune uveitis in different activation and disease states. Moreover, we also prospect for immunotherapies targeting different γδ T cell-related action pathways, providing a reference for exploring new drug for the treatment of autoimmune uveitis.

Abstract
OBJECTIVES The present study aimed to determine the pattern and cause of noninfectious uveitis in rheumatology practice. The secondary objective was to identify the pattern of treatment and outcomes. MATERIALS AND METHODS This retrospective cross-sectional study was conducted in the Department of Rheumatology, National Hospital and Medical Centre, Lahore, Pakistan. After receiving consent, electronic medical records (EMRs) of all patients with a diagnosis of noninfectious uveitis (NIU) from November 2019 to January 2023 were reviewed, and a total of 52 patients labeled as having noninfectious uveitis were identified. The collected data included age at diagnosis, anatomical location of uveitis, associated systemic disease, used medications, and outcomes. All cases had been diagnosed and assessed mutually by a rheumatologist and an ophthalmologist using the International Uveitis Study Group classification system to classify the pattern of uveitis by location, clinical course, and laterality and rule out the possibility of other ophthalmologic diseases. Disease activity was defined using the Standardization of Uveitis Nomenclature (SUN) guidelines. Data was analyzed on SPSS Statistics version 23 (IBM Corp, Armonk, NY, USA). RESULTS The mean age of the patients in this study was 36.02 ± 43.31 years, with 31 (59.6%) male patients. Anterior uveitis was the most common type observed among the patients at 55.8%, panuveitis was found in 25%, intermediate uveitis and posterior uveitis were seen in 9.6% each. Based on laterality, unilateral eye involvement was identified in 53.8% of patients. Spondyloarthritis (SpA) and idiopathic uveitis were observed in 34.6% and 28.8%, respectively. In this study, 28 (54.9%) patients were on conventional disease-modifying antirheumatic drugs (cDMARDDs), and 23 (45.1%) were on biological DMARDs. In the biologics group, 82% of patients were in remission in comparison to 60% in the cDMARDs group. CONCLUSION To the best of our knowledge, this is the first report on noninfectious uveitis in the Pakistani population. The study concluded that anterior uveitis is the most common type of uveitis and is more common in males. Spondyloarthropathy is one of the most common underlying systemic diseases. Human leukocyte antigen (HLA)-B27 is associated more with uveitis. Biologics are more effective than cDMARDs in controlling the disease. Collaborative work between different specialties resulted in early diagnosis of underlying systemic disease, better management plans, and disease outcomes. To obtain further details on noninfectious uveitis, a population-based study is needed in Pakistan.

Relationship between Vitreous IL-6 Levels, Gender Differences and C-Reactive Protein (CRP) in a Blood Sample of Posterior Uveitis. J Clin Med 2023; 12:jcm12051720. [PMID: 36902507 PMCID: PMC10003048 DOI: 10.3390/jcm12051720] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 02/08/2023] [Accepted: 02/19/2023] [Indexed: 02/24/2023] Open
Abstract
This study retrospectively determined the relationship between vitreous IL-6 levels and clinical and laboratory data collected from uveitis patients. We examined an unknown cause of posterior uveitis, collecting vitreous fluid to investigate vitreous IL-6 levels. The samples were analyzed in consideration of clinical and laboratory factors, such as the male/female ratio. The present study included 82 eyes from 77 patients with a mean age of 66.20 ± 15.41 years. The IL-6 concentrations of the vitreous specimens were 6255.0 ± 14,108.3 pg/mL in males and 277.6 ± 746.3 pg/mL in females, which was found to be a statistically significant difference (p = 0.048) (n = 82). There was also a statistically significant correlation between vitreous IL-6 concentrations, serum C-reactive protein (CRP) value and white blood cell counts (WBCs) (n = 82). In multivariate analysis, vitreous IL-6 levels were significantly correlated with gender and CRP in all cases (p = 0.048 and p < 0.01, respectively) and were also significantly correlated with CRP in non-infectious uveitis (p < 0.01). In infectious uveitis, there were no significant differences between IL-6 level and several variables. Vitreous IL-6 concentrations were higher in males than in females in all cases. In non-infectious uveitis, vitreous IL-6 levels were correlated with serum CRP. These results might suggest that intraocular IL-6 levels depend on gender differences in posterior uveitis, and intraocular IL-6 levels in non-infectious uveitis may reflect systemic inflammations, including increased serum CRP.

Abstract
PURPOSE To describe the clinical characteristics and longitudinal pattern of visual acuity (VA) of pediatric patients with uveitis at a tertiary center in Thailand. METHODS We retrospectively reviewed the records of children with uveitis ≤16 years who presented to the clinic between January 2010 and June 2020. RESULTS The mean age at onset was 9.1(±4.3) years; the main characteristics were chronic (64.4%), unilateral (68.6%), and panuveitis (39%). The common etiologies were ocular toxoplasmosis (11.9%), herpetic uveitis (10.2%), and ocular toxocariasis (6.8%). Further, 40% of the eyes presented with VA of ≤20/200; mean VA at baseline improved from 0.93 to 0.72 logMAR at 3 months after presentation (P < .001), the baseline VA of ≤20/200 was significantly associated with poor VA outcome at 1 year. CONCLUSION Chronic, unilateral, and panuveitis represented the majority of our children with uveitis. Infectious etiology was common. Significant VA improvement can be achieved with optimum management.

Abstract
Both inflammation and anti-inflammation are involved in the protection of retinal cells. Antagonists of the hypothalamic growth hormone-releasing hormone receptor (GHRHR) have been shown to possess potent anti-inflammatory properties in experimental disease models of various organs, some with systemic complications. Such effects are also found in ocular inflammatory and neurologic injury studies. In experimental models of mice and rats, both growth hormone-releasing hormone receptor agonists and antagonists may alleviate death of ocular neural cells under certain experimental conditions. This review explores the properties of growth hormone-releasing hormone receptor agonists and antagonists that lead to its protection against inflammatory responses induced by extrinsic agents or neurologic injures in ocular animal models.

Abstract
Non-infectious uveitis represents a heterogenous group of immune-mediated ocular diseases, which can be associated with underlying systemic disease. While the initial choice of treatment of non-infectious uveitis depends on a number of factors such as anatomical location and degree of inflammation, topical therapies often remain the initial choice of non-invasive therapy. In this narrative review, we aim to describe the literature on non-infectious uveitis, with specific focus on the current perspective on topical anti-inflammatory therapy.

Abstract
Noninfectious uveitis (NIU), an intraocular inflammation caused by immune-mediated reactions to eye antigens, is associated with systemic rheumatism and several autoimmune diseases. However, the mechanisms underlying the pathogenesis of uveitis are poorly understood. Therefore, we aimed to identify differentially expressed genes (DEGs) in individuals with NIU and to explore its etiologies using bioinformatics tools. GSE66936 and GSE18781 datasets from the gene expression omnibus (GEO) database were merged and analyzed. Functional enrichment analysis was performed, and protein-protein interaction (PPI) networks were constructed. A total of 89 DEGs were identified. Gene ontology (GO) enrichment analysis identified 21 enriched gene sets. Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis identified four core enriched pathways: antigen processing and expression signaling, natural killer (NK) cell-mediated cytotoxicity signaling, glutathione metabolic signal transduction, and arachidonic acid metabolism pathways. PPI network analysis revealed an active component-target network with 40 nodes and 132 edges, as well as several hub genes, including CD27, LTF, NCR3, SLC4A1, CD69, KLRB1, KIR2DL3, KIR3DL1, and GZMK. The eight potential hub genes may be associated with the risk of developing NIU. NK cell-mediated cytotoxicity signaling might be the key molecular mechanism in the occurrence and development of NIU. Our study provided new insights on NIU, its genetics, molecular pathogenesis and new therapeutic targets.

Abstract
Uveitis is a severe autoimmune disease, and a common cause of blindness; however, its individual cellular dynamics and pathogenic mechanism remain poorly understood. Herein, by performing single-cell RNA sequencing (scRNA-seq) on experimental autoimmune uveitis (EAU), we identify disease-associated alterations in cell composition and transcriptional regulation as the disease progressed, as well as a disease-related molecule, PIM1. Inhibiting PIM1 reduces the Th17 cell proportion and increases the Treg cell proportion, likely due to regulation of PIM1 to the protein kinase B (AKT)/Forkhead box O1 (FOXO1) pathway. Moreover, inhibiting PIM1 reduces Th17 cell pathogenicity and reduces plasma cell differentiation. Importantly, the upregulation of PIM1 in CD4+ T cells and plasma cells is conserved in a human uveitis, Vogt-Koyanagi-Harada disease (VKH), and inhibition of PIM1 reduces CD4+ T and B cell expansion. Collectively, a dynamic immune cellular atlas during uveitis is developed and implicate that PIM1 may be a potential therapeutic target for VKH. Uveitis is a complex autoimmune inflammatory disease of the eye and defining molecules involved is a priority. Here the authors use scRNA sequencing in mouse experimental autoimmune uveitis (EAU) and show PIM1 promotes the imbalance of Th17 and Treg cells, and find elevated PIM-1 in human uveitis disease.

Abstract
Introduction Uveitis is one of the common causes of visual impairment in Malaysia. It remains a challenging entity to diagnose and manage due to variation in its clinical presentation. This study aims to observe the demographic and clinical pattern of cases from the participating ophthalmology units in Malaysia. Methods This study involved prospective and multicentered data collection for patients newly diagnosed with uveitis from 1st January 2018 to 31st December 2018. Variables collected and analyzed included age, gender, ethnicity, nationality, state of origin, laterality, granulomatous or non-granulomatous uveitis, and etiology of uveitis. Results A total of 1199 newly diagnosed uveitis patients were analyzed within the study period. There was a significant association between the anatomical location of uveitis with age at presentation. The percentage of patients with anterior uveitis was higher in the ‘40 to 60’ years and ‘above 60’ years age groups at 52.1% (n = 210) and 61.3% (n = 114) respectively. In contrast the percentage of patients with posterior and panuveitis was higher in the 1 to 20 and 20 to 40 years age groups at 51.4% (n = 54) and 48.7% (n = 246) respectively. Sixty three percent of the patients presented with unilateral uveitis (n = 760, p < 0.001) vs bilateral. Non-granulomatous uveitis comprised 84.5% of all patients (n = 1013, p < 0.001) compared to granulomatous uveitis. Non-infectious etiology contributed to 65.7% of all patients (n = 788, p < 0.001) with the majority being unclassifiable uveitis (n = 686, 57.2%,). Specific inflammatory entities contributed to only 8.5% (n = 102) of the non-infectious causes with Vogt-Koyanagi-Harada (VKH) syndrome being the most common (n = 25, 2.1%,). Infectious uveitis comprised 34.3% (n = 411) with tubercular (TB) uveitis (n = 105, 8.8%) and viral uveitis (n = 107, 8.9%) contributing the most followed by ocular Toxoplasmosis (n = 93,7.8%).] Conclusion This study has highlighted the demographic data and common causes of uveitis in Malaysia.

Abstract
Uveitis is a sight-threatening disease that can be associated with many different etiologies. Successful treatment of uveitis relies on accurate diagnosis and prompt efficient therapy. History taking, physical and ocular examinations, systemic evaluations, and response to treatment provide crucial information to differentiate possible etiologies involved in the pathophysiology of intraocular inflammation. This article provides recommendations for a step-wise approach to patients with uveitis in Taiwan based on an expert meeting and consensus. Systemic evaluations for uveitis should be performed step-by-step and include investigation of patients' general systemic conditions, ruling out infectious etiologies, and obtaining evidential biomarkers to diagnose a specific disease entity.

Front Immunol 2022; 13:890543. [PMID: 35757729 PMCID: PMC9226308 DOI: 10.3389/fimmu.2022.890543] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 05/18/2022] [Indexed: 11/13/2022] Open
Abstract
Background Uveitis, a sight-threatening ocular inflammatory state, is associated with autoimmune diseases and systemic inflammation. This prolonged systemic inflammation may cause plaque formation in coronary arteries, subsequently resulting in acute coronary syndrome (ACS). Methods This retrospective, population-based study (15-year period) used the Longitudinal Health Insurance Database based on the National Health Insurance Research Database in Taiwan. Chi-square and Student's t-tests were used to examine differences between the study and comparison cohorts for categorical and continuous variables, respectively. Fine and Gray's competing risk model was used to determine the hazard ratio of the risk of ACS. Furthermore, the cumulative risk of ACS was determined using Kaplan-Meier analysis. Results A total of 1,111 patients with AS and uveitis were enrolled in this study cohort, and 4,444 patients with AS without uveitis were enrolled in the comparison cohort. After adjustment for age, sex, and comorbidities, patients with AS and uveitis demonstrated an increased risk of ACS compared to those without uveitis (adjusted hazard ratio: 1.675, p<0.001). In addition, Kaplan-Meier analysis revealed that patients with AS and uveitis had a significantly higher risk of ACS than those without uveitis (p<0.001). Age, diabetes mellitus, hypertension, hyperlipidemia, chronic obstructive pulmonary disease, asthma, and systemic steroids were significant risk factors for ACS. Both anterior uveitis and posterior segment involvement were associated with an increased risk of ACS in patients with AS. All-cause mortality was higher in the uveitis group (9.81%) than in the non-uveitis group (8.10%) (p=0.015). Conclusion Our analysis revealed that uveitis could potentially be a predictor of ACS in patients with AS. However, further prospective controlled studies are required to assess the association between uveitis and ACS in patients with AS.

Abstract
PURPOSE To investigate the clinical manifestations and systemic and ocular implications of nonneoplastic uveitis masquerade syndrome (NNUMS). DESIGN Retrospective case series. METHODS The clinical data of 830 consecutive patients who presented with uveitis at a tertiary referral center in northern Taiwan between August 2013 and August 2020 were analyzed. The clinical characteristics and outcomes of patients with NNUMS were evaluated. RESULTS Overall, 3.7% of patients were determined to have uveitis masquerade syndrome. Among them, 24 patients (77%; 34 eyes) were diagnosed as having NNUMS. The main presenting anatomical location was posterior uveitis (58.8%). In the NNUMS group, a high chorioretinal involvement rate (94.1%) and delayed diagnosis from symptom onset (45.8% cases were diagnosed after more than 90 days) were found. Multimodal imaging was the major decisive diagnostic factor. Systemic condition alterations requiring urgent treatment were noted in 29.2% of cases. Ocular complications were noted in 58.8% of cases; 60% of those were observed on referral. Following appropriate treatment, visual acuity could be maintained in 88.3% of cases. The 5 major categories of NNUMS were retinal vascular disorders, rhegmatogenous retinal detachment, retinal dystrophy, central serous chorioretinopathy, and uveal effusion syndrome. CONCLUSION NNUMS is a group of heterogeneous diseases with a complex diagnostic process and significant ocular and systemic effects. High awareness regarding common clinical manifestations is crucial for physicians to make the appropriate diagnosis and management.

Abstract
Background: To compare the efficacy and safety of advanced intravitreal therapeutic regimens, including a dexamethasone implant at 350 and 700 μg; a fluocinolone acetonide (FA) implant, 0.2 µg/day, 0.59 and 2.1 mg; intravitreal bevacizumab, 1.25 mg; intravitreal ranibizumab, 0.5 mg; intravitreal triamcinolone acetonide (IVTA), 2 and 4 mg; and standard of care (SOC, systemic therapy) for noninfectious uveitis. Methods: We searched the Cochrane Library database, EMBASE, Medline, clinicaltrials.gov until April 2021 with 13 RCTs (1806 participants) identified and conducted a pairwise and Bayesian network meta-analysis with random effects. Results: No specific regimen showed a statistically significant advantage or disadvantage to another treatment regimen with regard to efficacy. However, the FA implant, 0.59 mg was associated with a higher risk of cataract (RR 4.41, 95% CI 1.51–13.13) and raise in intraocular pressure (IOP) (RR 2.53 95% CI 1.14–6.25) compared with SOC at 24 months. IVTA, 4 mg at 6 months was associated with lower risk of IOP rising compared with FA implant, 0.2 µg/day at 36 months (RR 3.43 95% CI 1.12–11.35). Conclusion: No intravitreal therapeutic regimens showed a significant advantage or disadvantage with regard to efficacy. However, SOC was associated with lower risk of side effects compared with FA implants. IVTA, 4 mg, might be the best choice with lowest risk of IOP rising.

Uveitis as a Risk Factor for Developing Acute Myocardial Infarction in Ankylosing Spondylitis: A National Population-Based Longitudinal Cohort Study. Front Immunol 2022; 12:811664. [PMID: 35087531 PMCID: PMC8787117 DOI: 10.3389/fimmu.2021.811664] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Accepted: 12/17/2021] [Indexed: 12/17/2022] Open
Abstract
Background Ankylosing spondylitis (AS) is a chronic inflammatory disease. Excess cardiovascular risks were well recognized in patients with AS and were attributed to prolonged systemic inflammation. Uveitis is one of the most common extra-articular symptoms of AS and is also considered an indicator of systemic inflammation. This study aimed to investigate whether uveitis was a risk factor for developing acute myocardial infarction (AMI) in patients with AS using the National Health Insurance Research Database (NHIRD). Methods Data were collected from the NHIRD over a fifteen-year period. Variables were analyzed using the Pearson chi-square test and Fisher’s exact test. Risk factors for the occurrence of AMI were examined by calculating hazard ratio. Kaplan-Meier analysis was performed to compare the cumulative incidence of AMI in the uveitis and non-uveitis cohorts. Results A total of 5905 patients with AS were enrolled, including 1181 patients with uveitis (20%) and 4724 patients without uveitis (80%). The Kaplan–Meier method with the log-rank test showed that the uveitis group had a significantly higher cumulative hazard for patients with AMI than the non-uveitis group (p < 0.001). The adjusted hazard ratio (aHR) of AMI was higher in the uveitis group than in the non-uveitis group (aHR = 1.653, p < 0.001). Stratified analysis revealed that patients with uveitis had an increased risk of developing AMI regardless of their sex (male/female aHR = 1.688/1.608, p < 0.001). Patients with uveitis in all age groups were independently associated with an increased risk of developing AMI compared to those without uveitis (20–39 years/40–59 years/≥ 60 years, aHR = 1.550, 1.579, 3.240, p < 0.001). Patients with uveitis had a higher probability of developing AMI regardless of comorbidities. Uveitis patients with comorbidities had a higher risk of developing AMI compared to uveitis patients without comorbidities. Conclusion Uveitis is a significant risk factor for developing AMI in patients with AS. Physicians should be aware of the potential cardiovascular risk in AS patients with uveitis, especially simultaneously with other traditional risk factors of AMI. Further prospective studies are needed to elucidate the underlying mechanism between uveitis and AMI in patients with AS.

Mucosal-associated invariant T cells have therapeutic potential against ocular autoimmunity. Mucosal Immunol 2022; 15:351-361.

Abstract
Autoimmune uveitis is a sight-threatening disease induced by pathogenic T cells that recognize retinal antigens; it is observed in disorders including Vogt-Koyanagi-Harada disease (VKH). The roles of specific T cell subsets and their therapeutic potential against autoimmune uveitis are not fully understood. Here we conducted multi-parametric single-cell protein quantification which shows that the frequency of CD161highTRAV1-2+ mucosal-associated invariant T (MAIT) cells that recognize vitamin B2 metabolite-based antigens is decreased in relapsing VKH patients compared to individuals without active ocular inflammation. An experimental autoimmune uveitis (EAU) mouse model revealed that genetic depletion of MAIT cells reduced the expression of interleukin (Il) 22 and exacerbated retinal pathology. Reduced IL-22 levels were commonly observed in patients with relapsing VKH compared to individuals without active ocular inflammation. Both mouse and human MAIT cells produced IL-22 upon stimulation with their antigenic metabolite in vitro. An intravitreal administration of the antigenic metabolite into EAU mice induced retinal MAIT cell expansion and enhanced the expressions of Il22, as well as its downstream genes related to anti-inflammatory and neuroprotective effects, leading to an improvement in both retinal pathology and visual function. Taken together, we demonstrate that a metabolite-driven approach targeting MAIT cells has therapeutic potential against autoimmune uveitis.

Abstract
The cornea is a transparent, avascular and abundantly innervated tissue through which light rays are transmitted to the retina. The innermost layer of the cornea, also known as the endothelium, consists of a single layer of polygonal endothelial cells that serve an important role in preserving corneal transparency and hydration. The average corneal endothelial cell density (ECD) is the highest at birth (~3,000 cells/mm2), which then decrease to ~2,500 cells/mm2 at adulthood. These endothelial cells have limited regenerative potential and the minimum (critical) ECD required to maintain the pumping function of the endothelium is 400-500 cells/mm2. ECD < the critical value can result in decreased corneal transparency, development of corneal edema and reduced visual acuity. The condition of the corneal endothelium can be influenced by a number of factors, including systemic diseases, such as diabetes or atherosclerosis, eye diseases, such as uveitis or dry eye disease (DED) and therapeutic ophthalmological interventions. The aim of the present article is to review the impact of the most common systemic disorders (pseudoexfoliation syndrome, diabetes mellitus, cardiovascular disease), eye diseases (DED, uveitis, glaucoma, intraocular lens dislocation) and widely performed ophthalmic interventions (cataract surgery, intraocular pressure-lowering surgeries) on corneal ECD.

Abstract
PURPOSE To clarify the histologic basis of bacillary layer detachment (BALAD) through a review of the current literature and an analysis of retinal imaging. METHODS The literature for previous reports of BALAD were reviewed. An analysis of retinal images was performed to support anatomical conclusions. RESULTS A total of 164 unique patients with BALAD on optical coherence tomography (OCT) were identified from the published literature. Twenty-two underlying etiologies, all associated with subretinal exudation, were identified. Forty-one different OCT terminologies were found. The defining OCT feature of BALAD was a split at the level of the photoreceptor inner segment myoid creating a distinctive intraretinal cavity. Resolution of BALAD was followed by a rapid restoration of the ellipsoid zone. Histology of age-related macular degeneration eyes suggests that individual photoreceptors can shed inner segments. Furthermore, detachment of the entire layer of inner segments is a common postmortem artifact. It is proposed that BALAD occurs when outwardly directed forces promoting attachment of photoreceptor outer segments to the retinal pigment epithelium exceed the tensile strength of the photoreceptor inner segment myoid. CONCLUSION This review serves to strengthen the OCT nomenclature "bacillary layer detachment," based on specific reflectance information obtained by OCT and previously published histologic observations.

Abstract
OBJECTIVE The aim of this study was to evaluate the perifoveal and peripapillary microvascular structure in patients with Behçet's disease (BD) without clinically ocular involvement. METHODS Fifty-six eyes of 28 patients with Behçet's disease without clinically ocular involvement and 50 age-matched healthy eyes were included in this prospective study. Vessel densities (VD) of macula and optic nerve head, foveal avascular zone (FAZ), choroid capillary plexus (CCP) flow area, perifoveal capillary nonperfusion, capillary dilatation and/or telangiectasia and perifoveal capillary arcade disruption were analyzed with optical coherence tomography angiography (OCTA). The relationship between duration of disease and vessel densities was also evaluated. RESULTS The FAZ was significantly higher in the BD group (p < 0.001). VD of the foveal and parafoveal region in deep capillary plexus (DCP) were significantly lower in the BD group than in the control group (p < 0.001, p < 0.001). Total disc, peripapillary and inside-disc VD were significantly lower in BD group (p = 0.001, p = 0.002, p = 0.004). Perifoveal morphological changes in DCP were significantly higher in nonocular BD (p < 0.001, p < 0.001, p < 0.001). There was a mild negative correlation between disease duration and whole VD in DCP, total disc VD, peripapillary VD was determined (For whole VD in DCP, r = -0.400, p = 0.035; for total disc VD r = -0.396, p = 0.037; for peripapillary VD r = -0.442, p = 0.018). DISCUSSION Perifoveal and peripapillary microvascular changes that can be detected by OCTA may occur in Behçet's patients without clinically ocular involvement.

Abstract
Purpose: Non-infectious uveitis is a leading cause of vision loss in the developed world. The purpose of this systematic review is to investigate the epidemiology and risk factors of non-infectious uveitis over the last 50 years. Methods: A systematic literature search of Pubmed/MEDLINE database was performed in the 50-year period from January 1971 to January 2021, according to the PRISMA guidelines. Studies that assessed the epidemiology and risk factors for non-infectious uveitis were included. Results: Few epidemiologic studies focus specifically on non-infectious uveitis. In the Unites States, the estimated prevalence of non-infectious uveitis is 121/100,000. The incidence and prevalence varies considerably worldwide. Females and the working age group (20–50 years) appear to be the most affected. Smoking and vitamin D deficiency are the biggest risk factors for non-infectious uveitis, while pregnancy appears to be protective. Additional risk factors include presence of other autoimmune diseases (thyroid disease, diabetes, celiac), pre-eclampsia/eclampsia, psychological stress, and certain medications (bisphosphonates, immune checkpoint inhibitors, female hormone therapy, and etanercept). Discussion: Our systematic review summarizes the incidence and prevalence of non-infectious uveitis and associated modifiable and non-modifiable risk factors.

Abstract
Uveitis is characterized by inflammatory lesions of intraocular structures. It is one of the important manifestations in patients with Reiter’s syndrome, an inflammatory arthritis, which is caused by enteric infection with bacteria, including Salmonella typhimurium. Corticosteroids remain the most frequently used therapies against uveitis associating with inflammatory arthritis. However, the long-term administration of steroids results in many side effects, and some uveitis patients do not respond to steroid treatment. Non-steroidal treatments are needed for uveitis patients. Our previous study found that Janus kinase (JAK) 1/2 inhibitor, ruxolitinib could suppress the expression of proinflammatory mediators in the ciliary body and iris. However, the impacts of ruxolitinib on ophthalmic features in uveitic eyes are still unknown. In this study, Salmonella typhimurium endotoxin-induced uveitis (EIU) was induced in Sprague Dawley rats by the injection of lipopolysaccharide (LPS). Compared with LPS-induced rats treated with water, ruxolitinib significantly attenuated the clinical manifestations, infiltrating cells and protein exudation in the aqueous humor, and retina–choroid thickening. Amplitudes of b-wave in both scotopic and photopic electroretinogram (ERG), and the amplitude of a-wave in scotopic ERG in EIU animals were alleviated by ruxolitinib. Collectively, we propose ruxolitinib could attenuate endotoxin-induced uveitis and rescue visual functions in rats by inhibiting the JAK2-STAT3 pathway.

Abstract
Sarcoidosis is a poorly understood granulomatous disease that involves the lungs and/or intrathoracic lymph nodes in more than 90% of cases. Although pulmonary sarcoidosis is the leading cause of mortality in this disease, this review focuses on three sites of extrapulmonary involvement (heart, nervous system, and eyes), since involvement of any of these sites can be catastrophic, leading to death, debilitation, or blindness. Patients with cardiac, ocular and neurosarcoidosis necessitate a multidisciplinary approach with careful and long-term follow-up. Prompt diagnosis with imaging and/or biopsy and treatment is required to avoid irreversible damage. Corticosteroids are the mainstay of therapy and are often associated with rapid and durable remissions. Immunosuppressive or biologic agents are reserved for patients failing or experiencing side effects from steroids. Managing sarcoidosis requires vigilance, judgement, and awareness of the vagaries of this fascinating disease.

Prevalence and incidence rates and treatment patterns of non-infectious uveitis in Japan: real-world data using a claims database. Jpn J Ophthalmol 2021; 65:657-665. [PMID: 34181111 DOI: 10.1007/s10384-021-00850-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Accepted: 05/28/2021] [Indexed: 12/19/2022]
Abstract
PURPOSE To estimate the nationwide, longitudinal prevalence and incidence rates and assess treatment patterns of non-infectious uveitis (NIU) in Japan. STUDY DESIGN A retrospective study. METHODS Health insurance claims' data of patients with NIU were extracted from the Japan Medical Data Center (JMDC) database and analyzed descriptively (data extraction period, January 2011 to May 2017). Behçet's disease (BD), Vogt-Koyanagi-Harada (VKH) disease, and sarcoidosis were selected as the primary diseases of NIU. RESULTS From 2011 to 2016, the mean and median age of patients increased. Most (> 90%) patients were categorized as "undifferentiated NIU" (NIU without specific primary disease information after excluding BD-, VKH disease-, and sarcoidosis-associated NIU). Over 60% of patients with NIU were treated at non-hospital clinics, while the rest were treated at university, public, or other hospitals. The estimated prevalence rate of NIU was 386.5 per 100,000 persons (95% confidence interval [CI], 374.5-398.6) in 2011 and 439.3 per 100,000 persons (95% CI, 432.3-446.3) in 2016; the estimated incidence rate was 189.7 per 100,000 persons (95% CI, 181.2-198.5) in 2012 and 207.8 per 100,000 persons (95% CI, 202.2-213.5) in 2016. Most patients' prescribed uveitis drugs were ophthalmic drops over the first 6 months after patient presentation and entry into the JMDC database, followed by systemic corticosteroids. CONCLUSION The estimated prevalence of NIU in Japan in recent years was approximately 400 with incidence of 200 per 100,000 persons.

Abstract
PURPOSE The patterns of uveitis in Tokyo have recently changed due to advances in examination tools. We aimed to investigate the changes in the patterns of uveitis between 2004-2015 and 2016-2018. METHODS We retrospectively reviewed the data of 732 patients who visited the Uveitis Clinic at the University of Tokyo Hospital between January 2016 and December 2018. Background characteristics, laboratory results, and imaging findings were analysed. We compared the incidences of uveitis in 2016-2018 and 2004-2015 to identify changes in the patterns. RESULTS The most frequent diagnoses were sarcoidosis (8.9%), herpetic iridocyclitis (6.7%), intraocular lymphoma (5.5%), Vogt-Koyanagi-Harada disease (4.8%), unclassified acute anterior uveitis (4.6%), Behçet's disease (4.5%), bacterial endophthalmitis (2.9%), and Posner-Schlossman syndrome (2.6%). Suspected sarcoidosis (20.9%) was the most common cause of unclassified uveitis. The incidence of intraocular lymphoma was significantly higher in 2016-2018 than in 2004-2015. Between 2004 and 2018, herpetic iridocyclitis, bacterial endophthalmitis, and juvenile chronic iridocyclitis exhibited an increasing trend, and the incidences of Posner-Schlossman syndrome, unclassified acute anterior uveitis, Behçet's disease, and Vogt-Koyanagi-Harada disease exhibited a decreasing trend. CONCLUSION The changing patterns of uveitis were characterised by increases in the incidence of intraocular lymphoma. This may be attributed to recent advances in examination tools, the changes in the referred patient population, and the aging Japanese population.

Abstract
Previous studies have revealed an association between ocular surface disorders and air pollution, few studies have focused on the risk of uveitis. We aimed to investigate whether air pollution increases the risk of uveitis. We used the Taiwan Longitudinal Health Insurance Database (LHID) and the Taiwan Air Quality Monitoring Database (TAQMD) to conduct a retrospective cohort study. Air pollutant concentrations, including those of carbon dioxide (CO2), were grouped into four levels according to quartiles. The outcome was the incidence of uveitis, as defined in the International Classification of Diseases, Ninth Revision. We used univariable and multivariable Cox proportional hazard regression models to calculate the adjusted hazard ratios (aHRs) and determine the potential risk factors of uveitis. Overall, 175,489 subjects were linked to their nearby air quality monitoring stations. We found that for carbon monoxide, the aHRs of uveitis risk for the Q3 and Q4 levels were 1.41 (95% confidence interval (CI) = 1.23–1.61) and 2.19 (95% CI = 1.93–2.47), respectively, in comparison with those for the Q1 level. For nitric oxide, the aHRs for the Q3 and Q4 levels were 1.46 (95% CI = 1.27–1.67) and 2.05 (95% CI = 1.81–2.32), respectively. For nitrogen oxide (NOx), the aHRs for the Q2, Q3, and Q4 levels were 1.27 (95% CI = 1.11–1.44), 1.34 (95% CI = 1.16–1.53), and 1.85 (95% CI = 1.63–2.09), respectively. For total hydrocarbon (THC), the aHRs for the Q2, Q3, and Q4 levels were 1.42 (95% CI = 1.15–1.75), 3.80 (95% CI = 3.16–4.57), and 5.02 (95% CI = 4.19–6.02), respectively. For methane (CH4), the aHRs for the Q3 and Q4 levels were 1.94 (95% CI = 1.60–2.34) and 7.14 (95% CI = 6.01–8.48), respectively. In conclusion, air pollution was significantly associated with incidental uveitis, especially at high THC and CH4 levels. Furthermore, the uveitis risk appeared to increase with increasing NOx and THC levels.

Abstract
PURPOSE To investigate the epidemiology of uveitis in Japan and assess its changes over time. STUDY DESIGN Retrospective multicenter study METHODS: Sixty-six hospitals in Japan with uveitis specialty clinics participated in this retrospective nationwide survey. A questionnaire was sent to each hospital to survey the total number of patients who made a first visit to the outpatient uveitis clinic of each hospital between 1 April 2016 and 31 March 2017. The diagnosis of uveitis was based on guidelines when available or on commonly used diagnostic criteria. RESULTS In 2016, new patients with uveitis accounted for 3.2% of the total number of new patients with ophthalmic diseases. A total of 5378 patients were enrolled in the survey; 3408 cases could be classified with a specific uveitis entity, and 1970 cases were described as unclassified intraocular inflammation. Among the classified cases, the most frequent disease was sarcoidosis (10.6%), followed by Vogt-Koyanagi-Harada disease (8.1%), herpetic iritis (6.5%), acute anterior uveitis (5.5%), sclerouveitis (4.4%), Behçet's disease (4.2%), malignant disease (2.6%), acute retinal necrosis (1.7%), Posner-Schlossman syndrome (1.7%), and diabetic iritis (1.4%). The rates of sarcoidosis, Vogt-Koyanagi-Harada disease, and Behçet's disease were similar; however, the rate of herpes iritis increased (4.2-6.5%) when compared with the 2009 survey. CONCLUSIONS Some changes were observed between the previous nationwide surveys (2002 and 2009) and the present survey. It must be valuable to continue such nationwide epidemiologic surveys at regular intervals.

Abstract
Tumor necrosis factor alpha (TNF-α) was initially recognized as a factor that causes the necrosis of tumors, but it has been recently identified to have additional important functions as a pathological component of autoimmune diseases. TNF-α binds to two different receptors, which initiate signal transduction pathways. These pathways lead to various cellular responses, including cell survival, differentiation, and proliferation. However, the inappropriate or excessive activation of TNF-α signaling is associated with chronic inflammation and can eventually lead to the development of pathological complications such as autoimmune diseases. Understanding of the TNF-α signaling mechanism has been expanded and applied for the treatment of immune diseases, which has resulted in the development of effective therapeutic tools, including TNF-α inhibitors. Currently, clinically approved TNF-α inhibitors have shown noticeable potency in a variety of autoimmune diseases, and novel TNF-α signaling inhibitors are being clinically evaluated. In this review, we briefly introduce the impact of TNF-α signaling on autoimmune diseases and its inhibitors, which are used as therapeutic agents against autoimmune diseases.

Abstract
PURPOSE OF REVIEW Ocular sarcoidosis is one of the most common causes of uveitis worldwide. The diagnosis and treatment of patients with ocular sarcoidosis remains challenging in some cases. It is important for clinicians to keep up to date with new diagnostic and treatment tools for this disease. RECENT FINDINGS The International Workshop on Ocular Sarcoidosis diagnostic criteria were first proposed in 2009 and revised in 2017. The new criteria contained two parts: ocular presentation and systemic investigation. The diagnostic value of liver enzymes was reduced in the new criteria, whereas the value placed of lymphopenia and the CD4/CD8 ratio in bronchoalveolar lavage fluid were increased. Despite not being included in the criteria, recent studies have also highlighted the diagnostic value of serum soluble interleukin-2 receptors. Recent ophthalmologic imaging also provides useful insights for the differential diagnosis.Many new treatments for ocular sarcoidosis have been developed in recent years. The introduction of biological immunomodulatory agents for uveitis treatment represents a big improvement. Antitumor necrosis factor-alpha antibodies, including adalimumab, have been proven to be effective for treating ocular sarcoidosis. Many studies have also suggested that other biological agents could be effective and well tolerated. Newer intravitreal dexamethasone and fluocinolone implants have been developed. Patients treated with these implants have experienced good and sustained control of their intraocular inflammation. SUMMARY Diagnosis and treatment options for ocular sarcoidosis have changed over time. However, challenges still exist in some difficult patients. Future studies should focus on finding more sensitive biomarkers and developing more effective immunomodulatory treatments with longer efficacy and less side effects.

Abstract
PURPOSE To examine the diagnostic and prognostic roles of serum interleukin-6 levels in patients with uveitis. METHODS This was a retrospective observational case series. Demographic and clinical characteristics were compared between Group One (sixty patients) with normal serum IL-6 levels and Group Two (twenty patients) with high serum interleukin-6 levels. RESULTS Mean IL-6 level was 1.77 ± 0.97 pg/ml and 10.2 ± 9.7 pg/ml in Group One and Group Two respectively. Age, presence of systemic disease, and mean number of flare-ups were statistically significant (p = .015, p = .000, p = .03, respectively). Multivariate analysis was performed on variables that were statistically significant in univariate analysis and showed that three variables had significant correlation with IL-6 levels in both groups: systemic disease (OR = 10.83, p < .001), Age (OR = 0.95, p = .03) and number of flare-ups (OR = 2.9, p = .02). CONCLUSION Serum IL-6 levels can provide diagnostic and prognostic information in regard to the course of disease and its treatment.

Characteristics, evolution, and outcome of patients with non-infectious uveitis referred for rheumatologic assessment and management: an Egyptian multicenter retrospective study. Clin Rheumatol 2020; 40:1599-1610. [PMID: 32876781 DOI: 10.1007/s10067-020-05362-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 08/13/2020] [Accepted: 08/20/2020] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To investigate the characteristics, evolution, and visual outcome of non-infectious uveitis. METHODOLOGY Records of 201 patients with non-infectious uveitis (136 (67.7%) males and 84 (41.8%) juvenile-onset (≤ 16 years)) were retrospectively reviewed. Data were analyzed through Kruskal-Wallis and Mann-Whitney, chi-square (χ2) tests, and logistic regression. RESULTS The median disease and follow-up durations were 36 (interquartile range (IQR) 24-70) and 24 (IQR 10-36) months, respectively. Fifty-eight (28.9%) patients had persistently idiopathic uveitis, and 143 (71.1%) were associated with rheumatic diseases, of whom uveitis heralded, coincided with, and succeeded the rheumatic manifestation(s) in 62/143 (43.4%), 37/143 (25.9%), and 44/143 (30.7%) patients, respectively. Established rheumatic diseases were Behçet's disease (103/201 (51.2%)), juvenile idiopathic arthritis (13/201 (6.5%)), sarcoidosis (8/201 (4%)), seronegative spondyloarthropathy (7/201 (3.5%)), and Vogt-Koyanagi-Harada (7/201 (3.5%)), and other diagnoses were present in 5/201 (2.5%) patients. Patients with idiopathic uveitis were characterized by a juvenile-onset (p < 0.001), lower male predominance (p = 0.01), prevalent granulomatous (p < 0.001), and anterior (p = 0.001) uveitis. The median visual acuity at last visit was 0.3 (IQR 0.05-0.6). Visual loss was present in 45/201 (22.3%) patients (36/201 (17.9%) unilateral and 9/201 (4.4%) bilateral). Apart from a longer disease duration (p = 0.002), lower educational level (p = 0.03), and prevalent panuveitis (p < 0.001), visual loss was not associated with any other studied ocular or extra-ocular characteristics. CONCLUSION Behçet's disease (51.2%) and idiopathic uveitis (28.9%) were the most prevalent causes of non-infectious uveitis in our study. Visual loss (22.3%) was associated with a longer disease duration, lower education level, and prevalent panuveitis. Key Points • Most common causes of uveitis referred to rheumatologists were Behçet's disease and idiopathic uveitis. • Several rheumatic diseases initially presented only with uveitis, more commonly in adult and male patients. • Panuveitis was more frequent among patients with an established rheumatic disease, whereas granulomatous uveitis was uncommon. • Longer disease duration and presence of panuveitis were independently associated with visual loss.

Yin G, Zeng W, Hu K, Gao J, Liu J, Chen Y, Chen F. Parental Uveitis Influences Offspring With an Increased Susceptibility to the Experimental Autoimmune Uveitis. Front Immunol 2020; 11:1053. [PMID: 32612602 PMCID: PMC7308830 DOI: 10.3389/fimmu.2020.01053] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Accepted: 04/30/2020] [Indexed: 01/02/2023] Open
Abstract
Purpose: Previous studies have shown that parental abnormal physiological conditions such as inflammation, stress, and obesity can be transferred to offspring. The purpose of this study was to investigate the impact of parental uveitis on the development and susceptibility to experimental autoimmune uveitis (EAU) in offspring. Methods: Parental male and female B10RIII mice were immunized with interphotoreceptor retinoid binding protein (IRBP) 161–180 in complete Freund's adjuvant and were immediately allowed to mate. Gross examination of the offspring gestated with EAU was performed to determine the influence of parental uveitis on offspring development after birth. Gene expression profiles were analyzed in the affected eyes of offspring under EAU to identify differentially expressed genes (DEGs). Adult offspring were given 5, 25, and 50 μg IRBP161−180 to compare their susceptibility to EAU. Immunized mice were clinically and pathologically evaluated for the development of EAU. Ag-specific T-cell proliferation and IL-17 production from spleens and lymph nodes were evaluated on day 14 or 35 after immunization. Results: Hair loss, delay of eye opening, and swollen spleens in the offspring from parents with uveitis were observed from day 14 to 39 after birth. DEGs were involved in the immune system process, muscle system process, and cell development. The altered antigen processing and presentation, cell adhesion molecules, and phagosome in the eyes of the offspring from uveitis-affected parents were enriched. Offspring gestated with EAU showed a susceptibility to EAU and an earlier onset and higher severity of EAU compared to the control group mice. IRBP-specific lymphocyte proliferation and IL-17 production were observed in the EAU offspring with exposure to parental uveitis. Conclusions: The results suggest that mouse parents with uveitis can increase their offspring's susceptibility to EAU, probably through altering cell adhesion molecules and antigen processing and presentation related to the T-cell proliferation and Th17 response.

The Development of Dry Eye Disease After Surgery-Indicated Chronic Rhinosinusitis: A Population-Based Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17113829. [PMID: 32481640 PMCID: PMC7312531 DOI: 10.3390/ijerph17113829] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Revised: 05/25/2020] [Accepted: 05/26/2020] [Indexed: 11/29/2022]
Abstract
We aim to evaluate the risk of dry eye disease (DED) occurrence in patients with surgery-indicated chronic rhinosinusitis (CRS) via the national health insurance research database in Taiwan. After exclusion, patients with a diagnostic code of CRS and had received functional endoscopic sinus surgery (FESS) were regarded as having surgery-indicated CRS and enrolled in the study group, then each patient in the study group was age- and gender-matched to four non-CRS patients that served as the control group. The outcome was considered as the development of DED and Cox proportional hazard regression was used for the statistical analysis, which involved multiple potential risk factors of DED. A total of 6076 patients with surgery-indicated CRS that received FESS and another 24,304 non-CRS individuals were enrolled after exclusion. There were 317 and 770 DED events in the study group and the control group during the 16-year follow-up interval, and the study group demonstrated a significantly higher adjusted hazard ratio (1490, 95% confidence intervals (CI): 1.303-1.702) of DED development compared to the control group in the multivariable analysis. In addition, the cumulative probability analysis illustrated a positive correlation of DED occurrence and the disease period of surgery-indicated CRS (p < 0.0001). In the subgroup analysis, both genders revealed a higher but not significant incidence of developing DED in the study group. In conclusion, the existence of surgery-indicated CRS will increase the risk of developing DED, which correlated to the disease interval.

Abstract
Uveitis is a group of diseases characterized by intraocular inflammation, of which some are driven by autoinflammatory or autoimmune responses, such as Vogt-Koyanagi-Harada disease, Behçet's disease, uveitis associated with spondyloarthritis, ocular sarcoidosis, sympathetic ophthalmia and birdshot chorioretinopathy. These entities have various clinical forms, but genetic and biomarker data suggest that they share a common molecular basis, activation of the Interleukin (IL)-23/IL-17 pathway. Multiple factors including genetic predisposition, various cytokine imbalances, infectious agents and gut alterations are found to trigger an aberrant response of this pathway. The enhanced activity of the IL-23/IL-17 pathway is committed to the expansion and pathogenicity of Th17 cells. Evidence from animal models demonstrates that the development of pathogenic Th17 cells is responsible for the induction of experimental autoimmune uveitis. Further findings indicate that retinal pigment epithelium (RPE) cells may be a target of IL-17. IL-17 triggers downstream inflammatory cascades and causes dysfunction of RPE cells, which may affect retinal barrier function and thereby promote intraocular inflammation. Currently, several emerging drugs blocking the IL-23/IL-17 pathway have been assessed for the treatment of uveitis in pilot studies. The purpose of this is to summarize updated biological knowledge and preliminary clinical data, providing the rationale for further development and evaluation of novel drugs targeting the IL-23/IL-17 pathway in autoinflammatory and autoimmune uveitis. Future studies may focus on translational medicine targeting the IL-23/IL-17 pathway for the improvement of diagnosis and treatment of uveitis. In conclusion, activation of the IL-23/IL-17 pathway is a critical biological event and can be an important target for the treatment of autoinflammatory and autoimmune uveitis.

Abstract
PURPOSE Systemic diseases are frequently associated with uveitis but are often not recognised by clinicians. An estimate of the prevalence in a large-scale uveitis population is essential for understanding the epidemiological profile and may be helpful for clinical practice. DESIGN A nationwide survey. METHODS Data were obtained from a national database which included the registration of uveitis cases from 23 provinces, 5 autonomous regions and 4 municipalities across mainland China. The primary outcome was identification of a systemic disease associated with uveitis. RESULTS From April 2008 through August 2018, 15 373 uveitis patients were included in the study. Males accounted for 52.9%, and the mean (SD) age of uveitis onset was 35.4 (15.9) years. After standardisation for age, the prevalence of systemic disease among patients with uveitis was 30.8% (95% CI, 30.1% to 31.6%). Vogt-Koyanagi-Harada disease (VKH; age-standardised prevalence, 12.7%; 95% CI, 12.1% to 13.2%), Behçet's disease (BD; 8.7%; 95% CI, 8.3% to 9.2%), ankylosing spondylitis (AS; 5.0%; 95% CI, 4.6% to 5.3%) and juvenile idiopathic arthritis (JIA; 1.2%; 95% CI, 1.0% to 1.3%) were the most common entities among 36 different forms of systemic diseases identified. The prevalence was significantly higher in males (37.0%; 95% CI, 36.0% to 38.1%) than in females (23.6%; 95% CI, 22.6% to 24.6%), and also higher in bilateral uveitis patients (41.2%; 95% CI, 40.2% to 42.2%) compared with unilateral cases (14.3%; 95% CI, 13.4% to 15.2%), and was highest in panuveitis (59.5%; 95% CI, 58.2% to 60.8%). CONCLUSION Approximately one third of uveitis patients in this nationwide survey have an associated systemic disease, whereby VKH, BD, AS and JIA are the most frequent entities seen in China.

Analysis of inflammatory mediators in the vitreous humor of eyes with pan-uveitis according to aetiological classification. Sci Rep 2020; 10:2783.

Abstract
Treatment of uveitis is complicated because of its multiple aetiologies and elevation of various inflammatory mediators. To determine the mediators that are elevated in the vitreous humor according to the aetiology of the uveitis, we examined the concentrations of 21 inflammatory cytokines, 7 chemokines, and 5 colony-stimulating/growth factors in vitreous samples from 57 eyes with uveitis associated with intraocular lymphoma (IOL, n = 13), sarcoidosis (n = 15), acute retinal necrosis (ARN, n = 13), or bacterial endophthalmitis (BE, n = 16). Samples from eyes with idiopathic epiretinal membrane (n = 15), which is not associated with uveitis, were examined as controls. Heat map analysis demonstrated that the patterns of inflammatory mediators in the vitreous humor in eyes with uveitis were disease-specific. Pairwise comparisons between the 5 diseases showed specific elevation of interferon-α2 in ARN and interleukin (IL)-6, IL-17A, and granulocyte-colony stimulating factor in BE. Pairwise comparisons between IOL, ARN, and BE revealed that levels of IL-10 in IOL, RANTES (regulated on activation, normal T cell expressed and secreted) in ARN, and IL-22 in BE were significantly higher than those in the other 2 types of uveitis. These mediators are likely to be involved in the immunopathology of specific types of uveitis and may be useful biomarkers.

Abstract
Background: In recent years, the phenomenon of coexisting systemic autoimmune diseases (ADs) in patients with autoimmune encephalitis (AE) has been increasingly found, while its clinical significance remains unexplored. This study aimed to investigate the types and potential clinical associations of autoimmune comorbidities in patients with antibody-positive AE. Methods: A retrospective cohort study of patients with antibody-positive AE was conducted from 2011 to 2018. The demographics, clinical characteristics, and follow-up data were reviewed. Results: We enrolled 517 patients, among whom 45 were affected by one or more types of ADs, including Hashimoto's thyroiditis (HT) (n = 28), systemic lupus erythematosus (SLE) (n = 3), anaphylactoid purpura (n = 3), vitiligo (n = 3), Sjögren's syndrome (SS) (n = 2), chronic urticaria (n = 2), bullous pemphigoid (n = 1), uveitis (n = 1), myasthenia gravis (MG) (n = 1), and the coexistence of SLE and anaphylactoid purpura (n = 1). The proportion of patients with coexisting ADs was higher in those with anti–leucine-rich glioma-inactivated 1 (LGI1) encephalitis than in those with anti–N-methyl-d-aspartate receptor (NMDAR) encephalitis (13/111 vs. 16/307) (P = 0.021). In anti-NMDAR and anti-LGI1 encephalitis patients, there were no significant differences in the age at onset, sex ratio, proportion of patients with tumors, disease severity, or recurrence between the groups with and without ADs. Conclusions: One or more types of ADs developed in AE patients, and patients with anti-LGI1 encephalitis had a higher frequency of autoimmune comorbidities than those with anti-NMDAR encephalitis. And we found that autoimmune comorbidities did not affect the clinical course of AE.
