Abstract
PURPOSE To examine the clinical course and outcome in children with idiopathic chronic anterior uveitis (iCAU) and compare the results with age-matched children with juvenile idiopathic arthritis-associated uveitis (JIA-U). DESIGN Retrospective cohort study. METHODS Data regarding ocular complications, visual acuity, and systemic treatment were retrospectively collected for two patient groups that were matched regarding age and year of uveitis diagnosis. Outcome was evaluated using survival analysis. RESULTS The iCAU and JIA-U groups included 48 patients with 83 affected eyes and 48 patients with 73 affected eyes, respectively. Multivariate analyses showed that iCAU was associated with a higher prevalence of posterior synechiae (adjusted hazard rate [aHR]: 3.63; P < 0.001) and cataract surgery (aHR: 2.90; P = 0.006). Baseline visual acuity was worse in the iCAU group compared to the JIA-U group (20/25 vs. 20/20, respectively; P < 0.001), but improved in the iCAU group after 5 years (20/20 vs. 20/20, respectively; P = 0.052). At the 5-year follow-up, the younger children with iCAU (≤8 years of age at diagnosis) had a higher prevalence of posterior synechiae (aHR: 2.56; P = 0.007), secondary glaucoma (aHR: 16.0; P = 0.020), and cataract surgery (aHR: 4.79; P = 0.004) compared to older children with iCAU (≥9 years at diagnosis). CONCLUSIONS Vision-threatening ocular complications are more common in children with iCAU compared to children with JIA-U, particularly in cases in which the onset of uveitis occurred at ≤8 years of age. However, the long-term vision of these children can be improved with adequate treatment.

Abstract
Purpose To identify a serum biomarker signature that can help predict response to conventional synthetic disease-modifying antirheumatic drug (csDMARD) therapy in pediatric noninfectious uveitis. Methods In this case-control cohort study, we performed a 368-plex proteomic analysis of serum samples of 72 treatment-free patients with active uveitis (new onset or relapse) and 15 healthy controls. Among these, 37 patients were sampled at diagnosis before commencing csDMARD therapy. After 6 months, csDMARD response was evaluated and cases were categorized as “responder” or “nonresponder.” Patients were considered “nonresponders” if remission was not achieved under csDMARD therapy. Serum protein profiles were used to train random forest models to predict csDMARD failure and compared to a model based on eight clinical parameters at diagnosis (e.g., maximum cell grade). Results In total, 19 of 37 (51%) cases were categorized as csDMARD nonresponders. We identified a 10-protein signature that could predict csDMARD failure with an overall accuracy of 84%, which was higher compared to a model based on eight clinical parameters (73% accuracy). Adjusting for age, sex, anatomic location of uveitis, and cell grade, cases stratified by the 10-protein signature at diagnosis showed a large difference in risk for csDMARD failure (hazard ratio, 12.8; 95% confidence interval, 2.5–64.6; P = 0.002). Conclusions Machine learning models based on the serum proteome can stratify pediatric patients with uveitis at high risk for csDMARD failure. Translational Relevance The identified protein signature has implications for the development of clinical decision tools that integrate clinical parameters with biological data to better predict the best treatment option.

Abstract
In this systematic review, we provide an overview of the current state of intraoperative optical coherence tomography (iOCT). As iOCT technology is increasingly utilized, its current clinical applications and potential uses warrant attention. Here, we categorize the findings of various studies by their respective fields, including the use of iOCT in vitreoretinal surgery, corneal surgery, glaucoma surgery, cataract surgery, and pediatric ophthalmology. The trend observed in recent decades towards performing minimally invasive ophthalmic surgery has caused practitioners to recognize the limitations of using a conventional surgical microscope for intraoperative visualization. Thus, the superior visualization provided by iOCT can improve the safety of these surgical techniques and promote the development of new minimally invasive ophthalmic surgeries. Landmark prospective studies found that iOCT can significantly affect surgical decision making and can cause a subsequent change in surgical strategy, and the use of iOCT has potential to improve surgical outcome. Despite these advantages, however, iOCT is still a relatively new technique, and beginning users of iOCT can encounter limitations that can preclude their reaching the full potential of iOCT and in this respect several improvements are needed.

Abstract
Purpose Classical alleles of the human leukocyte antigen (HLA) complex have been linked to specific entities of pediatric noninfectious uveitis, yet genetic predisposition encoded by the HLA super-locus across the patient population remains understudied. Methods We performed next-generation full-length sequencing of HLA-A, HLA-B, HLA-C, HLA-DPB1, HLA-DQB1, and HLA-DRB1 in 280 cases. Dense genotype data from 499 Dutch controls from Genome of the Netherlands were imputed using an HLA-specific reference panel (n = 5225 samples from European ancestry). Cases and controls were compared using logistic regression models adjusting for sex. Results In total, 179 common and rare alleles were detected. Considering all cases and controls, HLA-DQB1*04:02 and HLA-DRB1*08:01 were identified as the principal HLA association, which was mainly driven by 92 cases with juvenile idiopathic arthritis-associated uveitis (JIA-U). The HLA-DQB1*04:02-HLA-DRB1*08:01 haplotype was also the primary association for the phenotypically similar idiopathic chronic anterior uveitis without arthritis (CAU). Also, HLA-DQB1*05:03 was an independent risk allele for CAU, but not in JIA-U. Analysis of 185 cases with other forms of uveitis revealed HLA-wide associations (P < 2.79 × 10−4) for HLA-DRB1*01:02, HLA-DRB1*04:03, and HLA-DQB1*05:03, which could be primarily attributed to cases with panuveitis. Finally, amino acid substitution modeling revealed that aspartic acid at position 57 that distinguishes the risk allele HLA-DQB1*05:03 (for CAU and panuveitis) from nonrisk alleles, significantly increased the binding capacity of naturally presented ligands to HLA-DQ. Conclusions These results uncovered novel shared HLA associations among clinically distinct phenotypes of pediatric uveitis and highlight genetic predisposition affecting the antigen presentation pathway.

ERAP2 Increases the Abundance of a Peptide Submotif Highly Selective for the Birdshot Uveitis-Associated HLA-A29. Front Immunol 2021; 12:634441. [PMID: 33717175 PMCID: PMC7950316 DOI: 10.3389/fimmu.2021.634441] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Accepted: 01/12/2021] [Indexed: 11/13/2022] Open
Abstract
Birdshot Uveitis (BU) is a blinding inflammatory eye condition that only affects HLA-A29-positive individuals. Genetic association studies linked ERAP2 with BU, an aminopeptidase which trims peptides before their presentation by HLA class I at the cell surface, which suggests that ERAP2-dependent peptide presentation by HLA-A29 drives the pathogenesis of BU. However, it remains poorly understood whether the effects of ERAP2 on the HLA-A29 peptidome are distinct from its effect on other HLA allotypes. To address this, we focused on the effects of ERAP2 on the immunopeptidome in patient-derived antigen presenting cells. Using complementary HLA-A29-based and pan-class I immunopurifications, isotope-labeled naturally processed and presented HLA-bound peptides were sequenced by mass spectrometry. We show that the effects of ERAP2 on the N-terminus of ligands of HLA-A29 are shared across endogenous HLA allotypes, but discover and replicate that one peptide motif generated in the presence of ERAP2 is specifically bound by HLA-A29. This motif can be found in the amino acid sequence of putative autoantigens. We further show evidence for internal sequence specificity for ERAP2 imprinted in the immunopeptidome. These results reveal that ERAP2 can generate an HLA-A29-specific antigen repertoire, which supports that antigen presentation is a key disease pathway in BU.

Abstract
PURPOSE To evaluate the efficacy of corticosteroid-sparing immunomodulatory therapy (IMT) in patients with recurrent and/or sight-threatening central multifocal choroiditis (MFC). METHODS This was a retrospective cohort study in a tertiary uveitis centre including all patients with MFC who have been treated with IMT for at least 12 months. Clinical data and imaging results were collected regarding the period prior to the start of IMT and at 3, 6, 12 and - where available - 24 months after the start of IMT. Main outcome measure was the number of annual recurrences of choroiditis with or without active choroidal neovascularization before and after the start of IMT. Secondary outcomes were the percentage of patients with (steroid-free) remission and the median time between the start of IMT and (steroid-free) remission. RESULTS Thirty-two patients (39 eyes) were included. At the start of IMT, none of the patients were in (steroid-free) remission. At 24 months, the probability of achieving remission and steroid-free remission was 88,5% and 50%, respectively. The median time to achieve remission and steroid-free remission was 21 and 83 weeks, respectively. In 17 patients (20 eyes) with available clinical data and imaging results for ≥ 12 months prior to the start of IMT, the mean number of recurrences/year decreased significantly from 1.40 ± 0.81 at baseline to 0.49 ± 0.47 (p = 0.001) after the start of IMT. CONCLUSIONS Preventive therapy with IMT should be considered in patients with recurrent and/or sight-threatening MFC to decrease the number of recurrences/year and to increase the prospects of achieving either remission or steroid-free remission.

Abstract
PURPOSE To evaluate the efficacy of adalimumab in patients with central multifocal choroiditis (cMFC) refractory to conventional corticosteroid-sparing immunomodulatory agents (IMT). METHODS Medical records were reviewed from all patients with cMFC and treated with adalimumab with follow-up of at least 12 months. The study focused on the 12 months prior to and after the start of adalimumab. The imaging results were independently evaluated by two ophthalmologists. The main outcomes were the number of patients without a relapse of disease activity in 12 months after the start of adalimumab and the ability to stop the systemic corticosteroids to evaluate the corticosteroid-sparing effect. RESULTS Twelve patients (18 eyes) were included. In 8/12 (67%) patients no relapse of disease activity was observed in the 12 months after the start of adalimumab. In 9/12 patients the systemic corticosteroid treatment could be stopped and in an additional 2 patients tapered to ≤7,5mg daily. In the 12 months before the start of adalimumab, the patients experienced a median of 3 (range 2-4) relapses of disease activity. Nine patients experienced relapses while treated with a combination of systemic corticosteroids (mean dose 13,6 mg; range 5-25 mg) and IMT. Moreover, 3 patients treated with IMT, experienced relapses after tapering and stopping the systemic corticosteroids. In all eyes (n = 5) with CNV before the start of adalimumab, the intravitreal anti-VEGF injections could be stopped after the start of adalimumab. CONCLUSIONS AND IMPORTANCE: Adalimumab may be effective in patients with cMFC refractory to IMT and may be considered as a treatment option in patients with cMFC.

Abstract
Purpose Patients with juvenile idiopathic arthritis (JIA) are prone to developing chronic anterior uveitis (JIA-U+). Although several risk factors for JIA-U+ have been identified, the underlying etiology is poorly understood. Histopathological studies demonstrate B cell infiltrates in eye tissues of patients with JIA-U+. Methods We performed transcriptome profiling of peripheral blood CD19-positive B cells taken from 14 cases with JIA-U+, 13 JIA cases without uveitis (JIA-U-), and five healthy controls. Deconvolution-based estimation was used to determine the immune cell fractions for each sample. Results Deconvolution results revealed that naive B cells made up on average 71% of the CD19-positive cell fractions analyzed. Differential expression analysis identified 614 differentially expressed genes (DEGs) between the groups at nominal significance and six genes at a false discovery rate of 5% (FDR < 0.05). Head-to-head comparison of all JIA-U- versus JIA-U+ revealed no DEGs in the CD19+ B cell pool (FDR < 0.05). However, principal component analysis based on a panel of key genes for B cell subsets revealed that JIA-U+ cases bifurcate into distinct clusters, characterized by markedly disparate expression for genes associated with specific memory B cell populations. CIBERSORT analysis of the overall transcriptome of the new uveitis cluster identified an increased proportion of memory B cells. Conclusion These data show that JIA-U- and JIA-U+ have a globally similar transcriptome considering the global peripheral CD19-positive B cell pool. However, heterogeneity in B cell memory genes among cases with uveitis suggests a role for specific memory B cell subsets in the etiology of JIA-U+.

Abstract
PURPOSE In uveitis, a prolonged implicit time of the cone b-wave is a characteristic electroretinogram (ERG) abnormality. We investigated whether this can improve or deteriorate over time and which clinical factors are associated with change. METHODS Prospective cohort study. Patients with a non-infectious uveitis were included. An ERG was measured in the first year of uveitis onset and a follow-up ERG one year later. Changes in the implicit time of the cone b-wave were investigated in relation to clinical parameters including the following: demographics, uveitis characteristics, treatment, best-corrected visual acuity, optical coherence tomography parameters and fluorescein angiography scores. RESULTS Of 98 eyes (63 patients), 40 showed a prolonged cone b-wave on the first ERG, which improved in 10 eyes. Eyes with an improved ERG more often had a panuveitis with initially a higher incidence of cells in the anterior chamber during the first ERG, which resolved at the time of their follow-up ERG. Five of the 58 eyes with a normal first ERG had a deteriorated follow-up ERG. These eyes had more frequently an active uveitis at the time of the follow-up ERG. Of the 78 eyes with a stable cone b-wave, 16 had a quiescent inflammation during follow-up. There were no differences in age or treatment. CONCLUSION In most patients with non-infectious uveitis, ERG abnormalities appear to be irreversible, even when the inflammation becomes quiescent. However, some ERGs improved, which was associated with reduction in inflammation of the anterior chamber due to panuveitis. In contrast, a worsened ERG was associated with a persistence of inflammation.

Abstract
Immune mediated inflammatory diseases (IMIDs) have similarities in pathophysiology and treatment. Not much is known, however, about health-related quality of life (HR-QoL) in IMIDs. We assessed and compared HR-QoL, using the validated EuroQoL 5-dimensions 5-levels questionnaire, in an observational cohort comprising 530 patients (67.5% female, mean age 49 years (95% CI 35.9-50.9), mean disease duration 31.0 months (95% CI 27.2-34.8)), with the following IMIDs: connective tissue diseases (32.6%), uveitis (20.8%), inflammatory arthritis (17.7%), psoriasis (15.5%), vasculitis (6.2%), primary antiphospholipid syndrome (4.2%), and autoinflammatory diseases (2.8%). Patients used either no anti-inflammatory therapy (31.5%), monotherapy (28.7%), or a combination of anti-inflammatory drugs (39.8%). The mean HR-QoL utility score was 0.75 (95% CI 0.72-0.78). Multinominal logistic regression analysis showed a statistically significant association between a very low HR-QoL (utility score (<0.70)) and female sex, rheumatological IMID or psoriasis, smoking or having smoked in the past, and current biological disease modifying anti-rheumatic drugs use.

Abstract
Purpose: To describe the results of tocilizumab treatment in children with refractory non-anterior uveitis.Methods: A case series of seven children with refractory non-anterior uveitis (onset ≤16 years) with leakage on fluorescein angiogram (FA) were treated with tocilizumab intravenously every 4 weeks (eight mg/kg). Minimum follow-up was 6 months. Reported outcomes are changes in BCVA, central macular thickness (CMT) on OCT image, FA scores, dose of systemic steroids, complications and side effects.Results: In all patients, there was an improvement of macular edema and capillary leakage on FA. The median FA score decreased from 14 (10-18) at baseline to 8 (2-9) after 6 months of treatment (p = .018). The CMT decreased from 321 (314-384) to 295 (255-312) (p = .043). BCVA improved in five eyes and worsened in one eye due to cataract. No systemic or ocular complications were reported.Conclusion: Tocilizumab is an effective therapeutic option for reducing disease activity in children with refractory non-anterior uveitis.

Abstract
Non-Hodgkin orbital lymphoma (NHOL) and idiopathic orbital inflammation (IOI) are common orbital conditions with largely unknown pathophysiology. To investigate the immune cell composition of these diseases, we performed standardized 29 parameter flow cytometry phenotyping in peripheral blood mononuclear cells of 18 NHOL patients, 21 IOI patients, and 41 unaffected controls. Automatic gating by FlowSOM revealed decreased abundance of meta-clusters containing dendritic cells in patients, which we confirmed by manual gating. A decreased percentage of (HLA-DR+ CD303+ CD123+ ) plasmacytoid dendritic cells (pDC) in the circulation of IOI patients and decreased (HLA-DR+ CD11c+ CD1c+ ) conventional dendritic cells (cDC) type-2 for IOI patients were replicated in an independent cohort of patients and controls. Meta-analysis of both cohorts demonstrated that pDCs are also decreased in blood of NHOL patients and highlighted that the decrease in blood cDC type-2 was specific for IOI patients compared to NHOL or controls. Deconvolution-based estimation of immune cells in transcriptomic data of 48 orbital biopsies revealed a decrease in the abundance of pDC and cDC populations within the orbital microenvironment of IOI patients. Collectively, these data suggest a previously underappreciated role for dendritic cells in orbital disorders.

Abstract
Non-Hodgkin orbital lymphoma (NHOL) and idiopathic orbital inflammation (IOI) are common orbital conditions with largely unknown pathophysiology that can be difficult to diagnose. In this study we aim to identify serum miRNAs associated with NHOL and IOI. We performed OpenArray® miRNA profiling in 33 patients and controls. Differentially expressed miRNAs were technically validated across technology platforms and replicated in an additional cohort of 32 patients and controls. We identified and independently validated a serum miRNA profile of NHOL that was remarkably similar to IOI and characterized by an increased expression of a cluster of eight miRNAs. Pathway enrichment analysis indicated that the miRNA-cluster is associated with immune-mediated pathways, which we supported by demonstrating the elevated expression of this cluster in serum of patients with other inflammatory conditions. The cluster contained miR-148a, a key driver of B-cell tolerance, and miR-365 that correlated with serum IgG and IgM concentrations. In addition, miR-29a and miR-223 were associated with blood lymphocyte and neutrophil populations, respectively. NHOL and IOI are characterized by an abnormal serum miRNA-cluster associated with immune pathway activation and linked to B cell and neutrophil dysfunction.

Abstract
PURPOSE This study sought to investigate whether there is an optimal position of the Dawson, Trick, and Litzkow (DTL) electrodes when measuring the full-field electroretinogram (ERG) for monitoring purposes. METHODS In 200 uveitis patients, an extended light-adapted (LA) ERG protocol was measured twice, incorporating the International Society for Clinical Electrophysiology of Vision standards. First, a LA ERG was measured with the DTL in the lower lid position (LLP) and thereafter in the fornix position. Differences in amplitudes and implicit times of a-waves, b-waves, and the 30 Hz peak were investigated. Intraclass correlation coefficients (ICCs) as well as coefficients of variation (CoV) were calculated, to assess both reliability and relative variability between the two DTL positions. RESULTS Implicit times showed no statistically significant differences between the two DTL positions. As expected, amplitudes at the different stimulus strengths were 1.12-1.19 higher in the LLP, but there were no significant differences in the CoV between the two DTL positions. The ICC was high for the b-wave and 30 Hz flicker response (0.842-0.979), but lower for the a-wave, especially for amplitudes (0.584-0.716). CONCLUSIONS For monitoring purposes in patients, we conclude that based on relative variability, no position is preferable above the other. However, because in most diseases amplitudes are decreased, the LLP may be chosen because it yields higher amplitudes. Whatever the choice, it is important to ensure that the DTL position remains stable during an ERG recording.

Abstract
PURPOSE This study sought to investigate retinal function in patients with noninfectious uveitis by using full-field electroretinography (ERG) and correlate the ERG to disease duration and severity of inflammation. DESIGN Prospective cohort study. METHODS Patients (n = 200) with noninfectious uveitis and a disease duration of <1 year (group A [n = 80]) and those with a disease duration of >5 years (group B [n = 120]) were included. ERGs of the total 355 uveitis eyes were measured according to an extended International Society for Clinical Electrophysiology of Vision protocol. ERG abnormalities were related to demographics and uveitis characteristics, including anatomical classification, duration of uveitis, severity of inflammation, best corrected visual acuity (BCVA), cystoid macular edema (CME), and the highest fluorescein angiography (FA) score during the course of the disease. RESULTS ERGs showed abnormalities in 235 eyes (66.2%). The most frequent and pronounced ERG abnormality was a prolonged implicit time of the cone b-wave (151 eyes [42.5%]), which was associated with vitritis (P = .005); cells in the anterior chamber (P = .007); the highest fluorescein angiography score (P = .011); age (P < 0.001); and pupil diameter (P < 0.001). BCVA was relatively good (0.05 logMAR [interquartile range {IQR}, 0.011, 0.22]) and not associated with this ERG abnormality. There were no differences between the ERG abnormalities in group A and those in group B and no significant associations between ERG abnormalities and anatomical classification or specific diagnoses. CONCLUSIONS ERG results are frequently affected in cases of noninfectious uveitis of all anatomic subtypes, including anterior uveitis without apparent inflammation of the posterior segment. ERG abnormalities appear to be associated with the severity of inflammation from both the present and the past and therefore may be seen even when signs of retinal inflammation have disappeared.

Abstract
Importance The diagnostic workup of patients suspected of having vitreoretinal lymphoma (VRL) is primarily based on vitreous fluid analysis, including the recently emerging myeloid differentiation primary response gene 88 (MYD88) mutation analysis. Aqueous humor paracentesis is a relatively less invasive and safer procedure than taking vitreous fluid specimens, and aqueous humor-based MYD88 mutation analysis would provide an additional liquid biopsy tool to diagnose and monitor patients with VRL. Objective To investigate whether the detection of MYD88 L265P by highly sensitive droplet digital polymerase chain reaction (ddPCR) is feasible in the vitreous fluid and aqueous humor of patients with VRL. Design, Setting, and Participants This cohort study includes aqueous humor and vitreous fluid samples from patients with VRL who were treated at the University Medical Center Utrecht, in Utrecht, the Netherlands, from August 2005 to August 2017. Ocular fluids were randomized and masked before MYD88 L265P analysis, which was performed using an in-house validated ddPCR platform. Patients with uveitis were included as a comparison group. Main Outcomes and Measures The presence of MYD88 L265P mutation detected by ddPCR in AH and VF. Results The study included 96 samples from 63 individuals, including 23 patients with VRL (of whom 10 were female and 13 male, with a mean [SD] age of 72 [7.3] years) and 40 individuals with uveitis (of whom 23 were female and 17 male, with a mean [SD] age of 58 [20.9] years). In 17 of 23 patients with VRL (74%), MYD88 L265P was detected; it was not detected in any of the patients with uveitis. It was detectable in both vitreous fluid and aqueous humor samples. In the paired samples, the mutation was detected in 8 of 9 aqueous humor samples (89%) of the MYD88 L265P-positive vitreous fluid samples. In vitreous fluid, the MYD88 ddPCR test showed a sensitivity of 75% (95% CI, 50%-92%) and a positive predictive value of 100%; in aqueous humor, sensitivity was 67% (95% CI, 42%-92%), and positive predictive value was 100%. Specificity was 100% in both fluids. After treatment, the mutation was no longer detectable in any ocular fluids. Conclusions and Relevance The high concordance between aqueous humor and vitreous fluid samples suggests that use of the easily accessible aqueous humor is nearly as informative as vitreous fluid in the identification of key somatic mutations in patients with VRL. This approach may provide an additional minimally invasive tool for accurate diagnosis, detection of recurrence, and monitoring of treatment.

Abstract
PURPOSE To study whether preventive laser or preventive vitrectomy is able to lower the risk of rhegmatogenous retinal detachment (RRD) in patients with acute retinal necrosis (ARN). DESIGN A retrospective, interventional case series. METHODS We performed a retrospective study of 59 patients (63 eyes) with ARN treated in a single tertiary referral center. We analyzed different groups with either no prophylaxis, prophylactic laser, or prophylactic vitrectomy. Main outcome measure was incidence of RRD. RESULTS Overall incidence of RRD was 44.4%, including 13% at presentation. In a crude analysis, the risk of RRD was highest in 33 patients with prophylactic laser (45.5%), lower in 15 patients with no prophylaxis (26.7%), and lowest in 7 patients with prophylactic vitrectomy (14.3%). Baseline best-corrected visual acuity differed between these groups, but zone and percentage of involved retina did not. In a multivariable model including prophylactic laser and ARN severity, only zone was predictive of RRD. CONCLUSION When correcting for severity of disease, we did not observe a reduction in the risk of RRD by prophylactic laser in eyes with ARN. Therefore, prophylactic laser may be abandoned. The role of prophylactic vitrectomy is still unclear, but deserves further investigation.

Abstract
PURPOSE Human leukocyte antigen-B27 (HLA-B27)-positive acute anterior uveitis (AAU) has a higher recurrence rate and shows more anterior chamber cell infiltration compared with HLA-B27-negative patients, suggesting distinct etiologies of these clinically overlapping conditions. To advance our understanding of the biology of AAU, we characterized the metabolic profile of aqueous humor (AqH) of patients with HLA-B27-associated AAU (B27-AAU) and noninfectious idiopathic AAU (idiopathic AAU). DESIGN Experimental laboratory study. METHODS AqH samples from 2 independent cohorts totaling 30 patients with B27-AAU, 16 patients with idiopathic AAU, and 20 patients with cataracts underwent 2 individual rounds of direct infusion mass spectrometry. Features predicted by direct infusion mass spectrometry that facilitated maximum separation between the disease groups in regression models were validated by liquid chromatography/tandem mass spectrometry-based quantification with appropriate standards. RESULTS Partial least square-discriminant analysis revealed metabolite profiles that were able to separate patients with B27-AAU from those with iodiopathic AAU. Pathway enrichment analysis, based on metabolites on which separation of the groups in the partial least square-discriminant analysis model was based, demonstrated the involvement of branched-chain amino acid biosynthesis, ascorbate and aldarate metabolism, the tricarboxylic acid cycle, and glycolysis-diverting pathways (eg, serine biosynthesis) across all investigated cohorts. Notably, the metabolite ketoleucine was elevated in B27-AAU across all 3 runs and moderately-but robustly-correlated with anterior chamber cell count (correlation coefficient range 0.41-0.81). CONCLUSIONS These results illustrate metabolic heterogeneity between HLA-B27-positive and HLA-B27-negative AAU, including an increase of branched-chain amino acid biosynthesis, that reflects disease activity in AAU.

Abstract
Birdshot Uveitis (Birdshot) is a rare eye condition that affects HLA-A29-positive individuals and could be considered a prototypic member of the recently proposed 'MHC-I (major histocompatibility complex class I)-opathy' family. Genetic studies have pinpointed the endoplasmic reticulum aminopeptidase (ERAP1) and (ERAP2) genes as shared associations across MHC-I-opathies, which suggests ERAP dysfunction may be a root cause for MHC-I-opathies. We mapped the ERAP1 and ERAP2 haplotypes in 84 Dutch cases and 890 controls. We identified association at variant rs10044354, which mediated a marked increase in ERAP2 expression. We also identified and cloned an independently associated ERAP1 haplotype (tagged by rs2287987) present in more than half of the cases; this ERAP1 haplotype is also the primary risk and protective haplotype for other MHC-I-opathies. We show that the risk ERAP1 haplotype conferred significantly altered expression of ERAP1 isoforms in transcriptomic data (n = 360), resulting in lowered protein expression and distinct enzymatic activity. Both the association for rs10044354 (meta-analysis: odds ratio (OR) [95% CI]=2.07[1.58-2.71], P = 1.24 × 10(-7)) and rs2287987 (OR[95% CI]: =2.01[1.51-2.67], P = 1.41 × 10(-6)) replicated and showed consistent direction of effect in an independent Spanish cohort of 46 cases and 2103 controls. In both cohorts, the combined rs2287987-rs10044354 haplotype associated with Birdshot more strongly than either variant alone [meta-analysis: P=3.9 × 10(-9)]. Finally, we observed that ERAP2 protein expression is dependent on the ERAP1 background across three European populations (n = 3353). In conclusion, a functionally distinct combination of ERAP1 and ERAP2 are a hallmark of Birdshot and provide rationale for strategies designed to correct ERAP function for treatment of Birdshot and MHC-I-opathies more broadly.

Abstract
Background: Non-infectious uveitis (NIU) is a severe intra ocular inflammation, which frequently requires prompt systemic immunosuppressive therapy (IMT) to halt the development of vision-threatening complications. IMT is considered when NIU cannot be treated with corticosteroids alone, which is unpredictable in advance. Previous studies have linked blood cell subsets to glucocorticoid sensitivity, which suggests that the composition of blood leukocytes may early identify patients that will require IMT. Objective: To map the blood leukocyte composition of NIU and identify cell subsets that stratify patients that required IMT during follow-up. Methods: We performed controlled flow cytometry experiments measuring a total of 37 protein markers in the blood of 30 IMT free patients with active non-infectious anterior, intermediate, and posterior uveitis, and compared these to 15 age and sex matched healthy controls. Results from manual gating were validated by automatic unsupervised gating using FlowSOM. Results: Patients with uveitis displayed lower relative frequencies of Natural Killer cells and higher relative frequencies of memory T cells, in particular the CCR6+ lineages. These results were confirmed by automatic gating by unsupervised clustering using FlowSOM. We observed considerable heterogeneity in memory T cell subsets and abundance of CXCR3-CCR6+ (Th17) cells between the uveitis subtypes. Importantly, regardless of the uveitis subtype, patients that eventually required IMT in the course of the study follow-up exhibited increased CCR6+ T cell abundance before commencing therapy. Conclusion: High-dimensional immunoprofiling in NIU patients shows that clinically distinct forms of human NIU exhibit shared as well as unique immune cell perturbations in the peripheral blood and link CCR6+ T cell abundance to systemic immunomodulatory treatment.

Abstract
Purpose The cause of noninfectious uveitis (NIU) is poorly understood but is considered to be mediated by a complex interplay between genetic, environmental, and-relatively unexplored-epigenetic factors. MicroRNAs (miRNAs) are noncoding small RNAs that are important epigenetic regulators implicated in pathologic signaling. Therefore, we mapped the circulating miRNA-ome of NIU patients and studied miRNA perturbations within the broader context of the immune system. Methods We designed a strategy to robustly identify changes in the miRNA profiles of two independent cohorts totaling 54 untreated patients with active and eye-restricted disease and 26 age-matched controls. High-resolution miRNA-ome data were obtained by TaqMan OpenArray technology and subsequent RT-qPCR. Flow cytometry data, and proteomic data spanning the cellular immune system, were used to map the uveitis-miRNA signature to changes in the composition of specific leukocyte subsets in blood. Results Using stringent selection criteria, we identified and independently validated an miRNA cluster that is associated with NIU. Pathway enrichment analysis for genes targeted by this cluster revealed significant enrichment for the PI3K/Akt, MAPK, FOXO, and VEGF signaling pathways, and photoreceptor development. In addition, unsupervised multidomain analyses linked the presence of the uveitis-associated miRNA cluster to a different composition of leukocyte subsets, more specifically, CD16+CD11c+HLA-DR- cells. Conclusions Together, this study identified a unique miRNA cluster associated with NIU that was related to changes in leukocyte subsets demonstrating systemic changes in epigenetic regulation underlying NIU.

Abstract
PURPOSE To describe the patterns of uveitis in South Africa. METHODS Prospective cross-sectional study. RESULTS One hundred and six patients were enrolled and 37.7% had human immune-deficiency virus (HIV) infection. Anterior and panuveitis occurred most frequently. Infectious, non-infectious and idiopathic uveitis were diagnosed in 66.0%, 17.0% and 17.0% of all cases, respectively. Eighty percent of HIV+ cases had infectious uveitis. Overall, intraocular tuberculosis (IOTB), herpetic and syphilitic uveitis were the commonest infectious causes. Sarcoidosis and HLA-B27-associated uveitis were the commonest non-infectious causes. In anterior uveitis, HIV+ cases most frequently had probable IOTB, syphilitic or idiopathic uveitis while HIV- cases had possible IOTB, idiopathic or HLA-B27-associated uveitis. In panuveitis, HIV+ cases mostly had syphilis, probable IOTB, toxoplasma and varicella-zoster virus whereas HIV- cases mostly had possible IOTB, sarcoidosis and idiopathic uveitis. CONCLUSION Infectious uveitis is common in South Africa, especially amongst HIV+ patients. Causes of anterior and panuveitis differ between HIV+ and HIV- patients.

Abstract
BACKGROUND/AIM To survey the frequency, character, severity and impact of ocular pain on quality of life in adult patients with non-infectious uveitis (NIU). METHODS This patient-requested cross-sectional survey study describes the results of three self-administered questionnaires (the National Eye Institute Visual Function Questionnaire, the 36-Item Short Form Health Survey (SF-36) and the McGill Pain Questionnaire Dutch Language Version) from 147 patients with NIUs from a university-based tertiary referral centre in Utrecht. RESULTS The mean Visual Function Questionnaire (VFQ) Ocular Pain Score of all patients with NIU was 72 (±24), which is significantly lower than an ocular disease-free reference group (90±15, P<0.0001), indicating more ocular pain. This was true for all types of NIU, regardless of the localisation: although Ocular Pain Scores were lower in patients with anterior uveitis (AU) compared with patients with non-AU (mean 62 (±24) vs 74 (±24), P=0.04), patients with non-AU still scored substantially lower than the reference group that had no ocular history (P<0.0001). Patients with NIU also scored significantly lower on all other VFQ subscales as well as on the SF-36 subscales 'Role Limitations due to physical problems', 'Vitality', 'General health' and 'Bodily Pain' compared with controls. The VFQ Ocular Pain subscale correlated with other quality of life subscales (both VFQ-25 and SF-36), indicating a relationship between pain and quality of life. CONCLUSION This study shows that ocular pain is highly prevalent in patients with NIU, regardless of the localisation. Furthermore, ocular pain has an impact on quality of life.
