Revising the Diagnosis of Idiopathic Uveitis by Peripheral Blood Transcriptomics. Am J Ophthalmol 2021; 222:15-23. [PMID: 32941857 DOI: 10.1016/j.ajo.2020.09.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 09/03/2020] [Accepted: 09/04/2020] [Indexed: 12/20/2022]
Abstract
PURPOSE To test the hypothesis that idiopathic uveitis can be categorized into subtypes based on gene expression from blood. DESIGN Case control study. METHODS We applied RNA-Seq to peripheral blood from patients with uveitis associated with 1 of 4 systemic diseases, including axial spondyloarthritis (n = 17), sarcoidosis (n = 13), inflammatory bowel disease (n = 12), tubulo-interstitial nephritis with uveitis (n = 10), or idiopathic uveitis (n = 38) as well as 18 healthy control subjects evaluated predominantly at Oregon Health and Science University. A high-dimensional negative binomial regression model implemented in the edgeR R package compared each disease group with the control subjects. The 20 most distinctive genes for each diagnosis were extracted. Of 80 genes, there were 75 unique genes. A classification algorithm was developed by fitting a gradient boosting tree with 5-fold cross-validation. Messenger RNA from subjects with idiopathic uveitis were analyzed to see if any fit clinically and by gene expression pattern with one of the diagnosable entities. RESULTS For uveitis associated with a diagnosable systemic disease, gene expression profiling achieved an overall accuracy of 85% (balanced average of sensitivity plus specificity, P < .001). Although most patients with idiopathic uveitis presumably have none of these 4 associated systemic diseases, gene expression profiles helped to reclassify 11 of 38 subjects. CONCLUSIONS Peripheral blood gene expression profiling is a potential adjunct in accurate differential diagnosis of the cause of uveitis. Validation of these results and characterization of the gene expression profile from additional discrete diagnoses could enhance the value of these observations.

Clin Ophthalmol 2021; 15:157-164. [PMID: 33469261 PMCID: PMC7811460 DOI: 10.2147/opth.s276109] [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: 08/08/2020] [Accepted: 11/13/2020] [Indexed: 12/14/2022] Open
Abstract
Purpose The aim of our study was to determine endothelin-1 (ET-1) concentration in chronic idiopathic uveitis in children and adolescents depending on anatomical location and grade of inflammation. Methods The cross-sectional study was conducted among 17 patients with chronic idiopathic uveitis and 22 healthy controls. Concentration of ET-1 in serum was determined using a commercially available ELISA kit. The concentration of C reactive protein (CRP) in serum was determined by immunoturbidimetric method using CRP4 reagent kit (Roche Diagnostics GmbH, Mannheim, Germany). Results Statistically significant difference between ET-1 concentration in patients with chronic idiopathic uveitis and controls was found 1.33 (1.22; 1.48) vs 1.93 (1.1; 3.11), p = 0.008). No correlations were found between ET-1 concentration and age, either in chronic idiopathic uveitis patients or controls. Nine out of 17 patients presented with anterior uveitis, 5 with posterior and 3 with panuveitis. There were no differences in ET-1 concentration between anterior, posterior and panuveitis (p = 0.634), and in terms of grade of inflammation. Conclusion ET-1 expression is disturbed in pediatric chronic idiopathic uveitis irrespective of the anatomical location and grade of inflammation. Lower expression of ET-1 plays a crucial role in disturbed vascular tone control and can result in permanent visual impairment in chronic non-infectious uveitis.

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.

Abstract
With the development of novel treatments for autoimmune disorders, it has become a popular research focus which mesenchymal stem cells (MSCs) have the capacity to counteract with autoimmune diseases progression. One of the underlying mechanisms behind their activities is the release of extracellular vesicles especially exosomes. MSC-derived exosomes are hypoimmunogenic nanocarriers which contain numerous immunoregulatory factors and similar to other exosomes, are able to pass through boundaries like the blood-brain barrier (BBB). Accumulating evidence provided by animal studies has demonstrated that MSC-derived exosomes, as a novel therapy, can re-induce self-tolerance, without subsequent complications reported for other treatments. Therefore, therapeutic applications of MSC-derived exosomes are contributing to core advances in the field of autoimmune diseases. Here, we briefly describe the biological characteristics of MSC-derived exosomes and review the experimentally verified outcomes for autoimmune disease therapy purposes.

Abstract
Acute anterior uveitis is the most common extra-articular clinical manifestation of spondyloarthropathy. Rheumatologists should be aware of uveitis, know how it presents, understand the differential diagnosis of uveitis and arthritis, and be familiar with the role of systemic medications in the treatment or prevention of uveitis.

Abstract
Uveitis is defined as intraocular inflammation. It is an extraarticular manifestation of many forms of joint disease, which include spondyloarthritis, juvenile idiopathic arthritis, and Behçet's disease. Rheumatologists may be asked to consult on the ophthalmologic care of patients with uveitis in order to identify an associated systemic illness. Diagnoses such as spondyloarthritis, sarcoidosis, and interstitial nephritis with uveitis are frequently overlooked by referring ophthalmologists. Alternatively, rheumatologists may be asked to help manage the patient's immunosuppression, including biologic therapy, which can be required to treat a subset of patients with uveitis. This review is intended to provide rheumatologists with the necessary information to facilitate collaboration in the comanagement of patients with uveitis.

Abstract
"Red eye" is used as a general term to describe irritated or bloodshot eyes. It is a recognizable sign of an acute/chronic, localized/systemic underlying inflammatory condition. Conjunctival injection is most commonly caused by dryness, allergy, visual fatigue, contact lens overwear, and local infections. In some instances, red eye can represent a true ocular emergency that should be treated by an ophthalmologist. A comprehensive assessment of red eye conditions is required to preserve the patients visual function. Severe ocular pain, significant photophobia, decreased vision, and history of ocular trauma are warning signs demanding immediate ophthalmological consultation.
