Relationship between ocular manifestations, laboratory findings, echocardiographic findings, and intravenous immunoglobulin resistance in Kawasaki disease.

BACKGROUND: This study investigates the incidence of ocular involvement in Kawasaki disease (KD) and evaluates the relationship between ocular manifestations, laboratory findings, echocardiographic findings, and intravenous immunoglobulin (IVIG) resistance. METHODS: We conducted a cross-sectional study with 58 KD patients from June 2021 to March 2023. For all patients, a complete ophthalmologic examination and echocardiography were performed in the acute phase before starting the treatment. We analyzed the age, sex, mean of white blood cell (WBC) count, platelet count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), echocardiographic findings and IVIG responses for all patients and compared the group with ocular involvement with the group without involvement. RESULTS: The incidence of bilateral acute conjunctivitis was 70.7%, while that of acute uveitis was 30%. Patients with uveitis had significantly higher rates of Coronary artery dilatation and IVIG resistance, as well as higher mean levels of WBC, platelet, and CRP compared to those without uveitis. (P < 0.05). Additionally, the age of patients with uveitis involvement was lower than those without involvement. No significant relationships existed between ESR, AST, or ALT values and uveitis (P > 0.05). Furthermore, no significant correlations existed between any examined items and acute bilateral conjunctivitis. CONCLUSION: Uveitis in KD is significantly associated with coronary artery dilatation, IVIG resistance, higher WBC count, platelet count, and CRP level.

Ocular lesions in patients with ulcerative colitis.

OBJECTIVE: Aim: To analyze the data and evaluate the prevalence of ocular lesions in patients with moderate ulcerative colitis. PATIENTS AND METHODS: Materials and Methods: We observed 112 patients aged 18-75 years old with clinically, endoscopically and histologically confirmed moderate ulcerative colitis which lasted at least 6 months. An ophthalmologic exam was performed to determine the presence of ocular symptoms. RESULTS: Results: Of the 112 patients with moderate ulcerative colitis, 21 (18,75%) had the following ocular lesions: episcleritis - 7 patients (6,25%), keratopathy - 5 patients (4,46%), uveitis - 5 patients (4,46%), cataract - 2 (1,78%) and scleritis - 2 (1.78%). CONCLUSION: Conclusions: Because ocular symptoms in patients with UC are often nonspecific, it may be beneficial to perform ophthalmologic examinations as a routine follow-up component of in such patients.

[CLINICAL MANIFESTATIONS OF AUTOIMMUNE DISEASES].

INTRODUCTION: Ocular inflammation, uveitis, represents over 40 distinct diseases, caused by infectious or non-infectious etiologies. Non-infectious uveitis may be related to systemic autoimmune diseases. Most uveitis patients are of working age, and prolonged disease may affect their independence and ability to work. Uveitis has various clinical manifestations and may result in the development of ocular complications and vision loss. Uveitis accounts for 10-15% of blindness in the developed world. Autoimmune diseases are increasing globally and often involve the eyes. Most cases occur in young active people and therefore any ocular changes have a longer effect. Symptoms may be mild but they might be severe, even blindness. It accounts for 10% to 15% of all causes of blindness among people of working age in the developed world. OBJECTIVES: To describe the ocular manifestation of uveitis related to systemic autoimmune diseases. We will describe ocular signs related to the disease and discuss the treatment approach to prevent the development of ocular complications and vision loss. METHODS: Review of clinical findings and treatment approach to non-infectious uveitis. CONCLUSIONS: Ocular involvement is commonly found in many autoimmune diseases. The severity of ocular disease varies between cases and complications may result in vision loss. Early diagnosis and treatment may prevent the development of ocular complications, maintaining visual acuity and patient independence.

New-onset or relapse of uveitis after rapid spreading of COVID-19 infection in China and risk factor analysis for relapse.

BACKGROUND: The aim of this study was to report the clinical profile of new-onset and relapse of uveitis following rapid spreading of coronavirus disease 2019 (COVID-19) infection due to change of anti-COVID-19 policies in China and investigate potential risk factors for inflammation relapse. METHODS: In this retrospective case-control study, patients with new-onset or a history of uveitis between December 23, 2022, and February 28, 2023, were included to assess the influence of COVID-19 infection on uveitis. Detailed information on demographic data, clinical characteristics, treatment measures, treatment response, and ocular inflammatory status before and after COVID-19 infection was collected. RESULTS: This study included 349 patients with a history of uveitis. The uveitis relapse rate was higher (28.8%, n = 288) in those with COVID-19 infection than in patients without COVID-19 infection (14.8%, n = 61) (P = 0.024). Among the relapse cases, 50.8% experienced a relapse of anterior uveitis, while 49.2% had a relapse of uveitis involving the posterior segment. Multivariable regression analysis indicated a positive correlation between disease duration and uveitis relapse, while the last relapse exceeding one year before COVID-19 infection and the use of methotrexate during COVID-19 infection were negatively correlated with relapse of uveitis. Thirteen patients who developed new-onset uveitis following COVID-19 infection were included; among them, three (23.1%) had anterior uveitis and 10 (76.9%) had uveitis affecting the posterior segment. Regarding cases involving the posterior segment, four patients (30.8%) were diagnosed with Vogt-Koyanagi-Harada disease. CONCLUSIONS: COVID-19 infection increases the rate of uveitis relapse. Long disease duration is a risk factor, while time since the last relapse more than 1 year and methotrexate use are protective factors against uveitis relapse.

Role of screening for uveitis in subjects with sarcoidosis.

BACKGROUND AND OBJECTIVES: Ocular involvement is common in sarcoidosis. Our study aimed to evaluate the role of screening for uveitis in subjects with sarcoidosis. METHODS: Retrospective case series of 88 subjects with a pre-existing diagnosis of sarcoidosis, with no previous diagnosis of uveitis, reviewed by Ophthalmology at Auckland District Health Board between January 2016 and May 2022. RESULTS: Among those undergoing a screening examination, uveitis was observed in 27.8% (15 out of 54 subjects). In those presenting with acute eye symptoms, uveitis was observed in 94.1% (32 out of 34 subjects). Sarcoid uveitis was diagnosed in a total of 50 out of 88 subjects (56.8%). 45 subjects required ocular treatment. Sarcoid uveitis was observed in 6 out of 27 subjects (22.2%) who were entirely asymptomatic at screening. On multivariate analysis, blurring of vision (OR 26.2 p < 0.001), eye pain (OR 7.3 p = 0.014) and respiratory disease (OR 7.1 p = 0.044) were associated with increased risk of sarcoid uveitis. In the 41 subjects with no uveitis at initial examination, 3 subjects (7.3%) subsequently developed uveitis. CONCLUSION: Our study highlights the importance of ophthalmic screening of all patients with systemic sarcoidosis, even in asymptomatic patients. With a high correlation of ocular symptoms in diagnosis of sarcoid uveitis, ophthalmologists should educate patients to look out for the development of symptoms of ocular inflammation, and clinicians who continue follow up for systemic sarcoidosis should remind patients to watch carefully for these symptoms to facilitate timely diagnosis and intervention.

Ocular Sarcoidosis.

Sarcoidosis frequently affects the eye and can do so in many different ways. Sarcoidosis causing uveitis can have distinctive features that facilitate identifying sarcoidosis as the cause of the uveitis. Progress is being made in elucidating ocular sarcoidosis, as for example, by transcriptomics, genetics, therapy, and imaging.

[Diagnostic modalities of a Behçet uveitis]. / Comment j'explore une uvéite de Behçet.

Behçet disease is a chronic multisystemic inflammatory condition. The ocular disease mainly manifests as a bilateral, non-granulomatous, posterior uveitis or panuveitis, associated with occlusive retinal vasculitis. Uveitis is frequent in Behçet disease, it may be severe, and visually threatening. Early diagnosis and aggressive treatment are mandatory to preserve visual function. Therefore, the goal of this review is to describe the new diagnosis tools and therapeutic guidelines allowing for a significant improvement of the visual prognosis.

La maladie de Behçet est une pathologie inflammatoire chronique multisystémique. L'atteinte oculaire se caractérise le plus souvent par une panuvéite ou uvéite postérieure bilatérale récidivante, non granulomateuse, associée à une vascularite rétinienne occlusive. L'uvéite associée à la maladie de Behçet est fréquente, sévère et potentiellement cécitante en l'absence d'un diagnostic précoce et d'un traitement adapté. L'objectif de cette revue est de décrire les outils diagnostiques et thérapeutiques ayant permis une amélioration significative du pronostic visuel.

New onset or recurrence of uveitis following COVID-19 infection.

BACKGROUND: While the 2019 novel coronavirus disease (COVID-19) pandemic has resulted in millions of cases worldwide, there is increasing recognition of a wide range of ocular manifestations associated with the virus, including uveitis. Uveitis is an inflammatory condition of the uveal tract of the eye that can lead to permanent vision loss if not treated promptly. Here we report a retrospective observational study of patients who presented with new onset or recurrent uveitis following COVID-19 infection. METHODS: This is a retrospective observational study conducted at the Beijing Tongren Hospital. We identified patients who presented with symptoms of non-infectious active uveitis with positive real-time reverse transcription polymerase chain reaction (RT-PCR) of COVID-19 within 4 weeks. All patients received ophthalmic examinations, including anterior and posterior segment imaging, to assess the extent of ocular involvement. RESULTS: The 18 patients with a total of 33 eyes included in this study presented with symptoms of active uveitis within 4 weeks of their positive COVID-19 RT-PCR test. Among them, 9 patients presented with the development of uveitis following COVID-19 infection, and 9 patients had relapsed uveitis after COVID-19 infection. Treatment with corticosteroids resulted in improvement of symptoms and resolution of inflammation in all cases. In this study, all patients did not experience any adverse drug reactions during treatment. CONCLUSION: Our observational study highlights the potential for new onset or recurrence of uveitis following COVID-19 infection.

Screening for juvenile idiopathic arthritis associated uveitis with laser flare photometry in the pediatric rheumatology office: a prospective observational study.

BACKGROUND: Juvenile Idiopathic Arthritis (JIA) Associated Uveitis (JIA-U) remains one of the most serious complications of JIA in children. Historically, pediatric JIA is diagnosed by an Optometrist or Ophthalmologist; however, barriers to scheduling increase wait times that may delay diagnosis and treatment. The purpose of this study was to evaluate laser flare photometry (LFP) use to diagnose JIA-U in the Pediatric Rheumatology clinic for patients with JIA. METHODS: This prospective, observational study assessed pediatric patients diagnosed with JIA without a previous history of uveitis between January 2020 and September 2022. All patients underwent at least one evaluation of both eyes using a Kowa FM-600 laser flare photometer during a routine Rheumatology appointment, as well as a standard slit lamp examination (SLE) by optometry or ophthalmology during routine clinical care. Data collected at patient visits included demographics, JIA characteristics, treatment, LFP readings, and anterior chamber (AC) cell grade score utilizing the SUN grading system. Data were summarized using descriptive analyses and the uveitis false positive rate was calculated. RESULTS: The study cohort included 58 pediatric patients diagnosed with JIA. The mean age was 8.4 years (1.2-16.3 years) at diagnosis and 11.9 (4.8-16.5 years) at enrollment. The mean duration of disease at time of enrollment was 42 months (range; 0-157 months). Participants were predominantly female (n = 43, 74.1%) and white/Caucasian race (n = 37, 63.8%). The most common JIA subtypes included persistent oligoarticular JIA (n = 19, 32.8%), and RF negative polyarticular JIA (n = 12, 20.7%). There were 12 ANA positive patients (20.7%). At enrollment, 16 patients (27.6%) were not on medications, with 20 (34.5%) on methotrexate, 20 (34.5%) on adalimumab, 6 (10.3%) on tocilizumab, and 5 (8.6%) on etanercept. During the study period, no eye exams detected active uveitis based on SLE with a SUN grade over 0. However, of the 135 LFP readings, 131 (97.0%) were normal, yielding a false positive rate of 3% (95% CI: 0.8%, 7.4%). CONCLUSIONS: LFP is a non-invasive tool that can be utilized in the pediatric rheumatology clinic to evaluate for JIA-U. There is a low false positive rate of LFP when compared with standard slit lamp exam.

A Case of Persistent Macular Edema and a Disappearing Tattoo.

PURPOSE: To describe a case of macular edema (ME), uveitis, and a disappearing tattoo. METHODS: A single case report from a tertiary referral center. RESULTS: The patient described in the following case report developed ME 15 years after a recently acquired tattoo on his arm had developed an erythematous rash and subsequently spontaneously disappeared with pathology consistent with a granulomatous process. Chest imaging identified the development of hilar lymphadenopathy that had not been previously noted. CONCLUSIONS: This case represents a unique presentation of the delayed development of sarcoidosis many years after the patient had lost a tattoo to a dermal granulomatous reaction to the tattoo ink.

Tubulointerstitial Nephritis and Uveitis Syndrome (TINU) after Intake of Dietary Supplement.

INTRODUCTION: The pathogenesis of tubulointerstitial nephritis with uveitis syndrome (TINU) is thought to be an interplay between environmental and genetic factors leading to an inappropriate immune response. METHODS: Report of a clinical case. RESULTS: We present a case of TINU syndrome which meets the clinical and anatomopathological features according to the classification criteria of the standardization of uveitis nomenclature (SUN) working group. The only possible causal agent was found to be the intake of a nutritional supplement. CONCLUSION: Our case highlights the role of environmental factors as triggers for this disorder.

Efficacy and Safety of Adalimumab in Patients with Behçet Uveitis: A Systematic Review and Meta-Analysis.

PURPOSE: To examine the long-term efficacy and safety of adalimumab (ADA) in patients with Behçet uveitis (BU). METHODS: A systematic review and meta-analysis of observational studies was performed. Pooled results are presented as mean difference or standardized mean difference (std diff) and 95% confidence intervals (CI). Visual acuity (VA), intraocular inflammation grade, central macular thickness, corticosteroid (CS) sparing effect and adverse events were evaluated. RESULTS: Ten studies were included finally for quantitative and qualitative synthesis. ADA therapy resulted in 0.124 (95%CI: 0.084, 0.165) logMAR improvement in VA. In addition, ADA therapy resulted in decreased grade of intraocular inflammation [std diff, -1.187 (95%CI: -1.508, -0.866)] and macular thickness [std diff, -0.564 (95%CI: -0.843, -0.286)] and caused a decrease in CS dosage [std diff, -1.809 (95%CI: -2.420, -1.198)]. The pooled rate of overall adverse events for ADA in 301 patients was 8.5% (95%CI: 0.039, 0.177). CONCLUSION: ADA is an efficient therapy that improves VA and controls intraocular inflammation, macular edema and retinal vasculitis. As the disease exposure time increased, improvement in VA was less. The safety and CS-sparing effect of ADA were demonstrated with few adverse effects. The results provided evidence that ADA can be used safely and efficiently as the first-line drug in patients with BU.

UGH Syndrome Resolution after IOL Explantation and Concomitant Carlevale IOL Implantation.

OBJECTIVE: To examine the use of Carlevale IOL placement in patients with UGH, and to evaluate surgical outcomes. DESIGN: In this retrospective study, 28 patients with UGH syndrome that were subjected to IOL explantation and concomitant Carlevale IOL implantation were included in the study. METHODS: Information about VA, IOP, number of glaucoma medication, need for glaucoma surgery, presence of hemorrhage and inflammation were recorded up to 6 months after the procedure. RESULTS: We found a statistically significant increase in mean visual acuity and complete resolution of uveitis in all patients. Mean IOP and the mean number of glaucoma medications were significantly decreased postoperatively, while 14% of patients required additional glaucoma surgery. CONCLUSIONS: IOL explantation and concomitant Carlevale IOL implantation may provide a viable solution for UGH syndrome resolution, increases visual acuity, and decreases the need for glaucoma medication.

The risk factors for uveitis among psoriatic arthritis patients: a population-based cohort study.

OBJECTIVE: To assess the frequency of uveitis in patients with psoriatic arthritis (PsA) in the era of biologics and to identify risk factors associated with uveitis. METHODS: A retrospective matched cohort study was conducted within the database of a large healthcare provider. Newly diagnosed 6147 adult PsA patients between 2005 and 2020 were matched by the index date of PsA diagnosis, age, sex, and ethnicity to 23,999 randomly selected controls. This cohort was used to examine the association between PsA and uveitis. An additional analysis was conducted within the PsA group to identify uveitis risk factors, using two analytic approaches: a retrospective cohort study and a nested case-control study. RESULTS: Uveitis was diagnosed in 107 patients in the PsA group (1.7%) vs 187 (0.8%) patients in the control group (adjusted HR, 2.38, 95% CI 1.80-3.15, p<0.005) and was similar when the analysis was confined to patients without past uveitis. Uveitis was diagnosed more in females (2.1% vs 1.3%, HR 1.61, 95% CI 1.09-2.40, p<0.05), and was acute in all cases. Anterior uveitis was documented in 41.1% of the cases, 64.5% unilateral, and 9.3% bilateral. In the PsA group, using nested case control approach, only past uveitis [adjusted OR 136.4 (95% CI 27.38-679.88), p<0.005] and treatment with etanercept [adjusted OR 2.57 (95% CI 1.45-4.57), p=0.001] were independently associated with uveitis. Only one PsA patient with uveitis (out of 107) required systemic oral treatment with prednisone, while the rest of the patients were treated with topical glucocorticosteroids only. CONCLUSION: PsA is associated with increased risk of uveitis. Past uveitis and treatment with etanercept were associated with higher risk of uveitis. Key Points • Psoriatic arthritis (PsA) is a major risk factor for uveitis with hazard ratio of 2.38 compared to healthy individuals without PsA. • Among PsA patients, the past event of uveitis and treatment with etanercept are risk factors for uveitis. • Uveitis in patients treated with biologics for their PsA requires topical therapy only in most of the cases.

A clinical overview of paediatric sarcoidosis: Multicentre experience from Turkey.

OBJECTIVES: We aimed to outline the demographic data, clinical spectrum, and treatment approach of sarcoidosis in a large group of patients and sought to figure out the variations of early-onset (EOS) and late-onset paediatric sarcoidosis (LOS). METHODS: The study followed a retrospective-descriptive design, with the analysis of medical records of cases diagnosed as paediatric sarcoidosis. RESULTS: Fifty-two patients were included in the study. The median age at disease onset and follow-up duration were 83 (28.2-119) and 24 (6-48) months, respectively. Ten (19.2%) cases had EOS (before 5th birthday) and 42 (80.7%) cases had LOS. The most common clinical findings at the time of the disease onset were ocular symptoms (40.4%) followed by joint manifestation (25%), dermatological symptoms (13.5%), and features related to multi-organ involvement (11.5%). Anterior uveitis was the most common (55%) one among ocular manifestations. Patients with EOS displayed joint, eye, and dermatological findings more commonly than patients with LOS. The recurrence rate of disease in patients with EOS (5.7%) and LOS (21.1%) were not statistically different (P = .7). CONCLUSIONS: Patients with EOS and LOS may present with variable clinical features and studies addressing paediatric sarcoidosis cases in collaboration between disciplines will enhance the awareness of this rare disease among physicians and assist early diagnosis with lesser complications.

Diagnostic delay is associated with uveitis and inflammatory bowel disease in AS: a study of extra-musculoskeletal manifestations in SpA.

OBJECTIVES: To examine the prevalence of extra-musculoskeletal manifestations (EMM) and the association between diagnostic delay and their incidence in AS and PsA. METHODS: This was a retrospective, cohort study comprising two single centre cohorts in Europe and one multicentre cohort in Latin America (RESPONDIA). Crude prevalence of EMMs (uveitis, IBD and psoriasis) was calculated across geographic area and adjusted by direct standardization. Cox proportional hazard analysis was performed to assess the association between diagnostic delay and EMM incidence. RESULTS: Of 3553 patients, 2097 had AS and 1456 had PsA. The overall prevalence of uveitis was 22.9% (95% CI: 21.1, 24.8) in AS and 3.8% (95% CI: 2.9, 5.0) in PsA; 8.1% (95% CI: 7.0, 9.4) and 2.1% (1.3, 2.9), respectively, for IBD; and 11.0% (95% CI: 9.7, 12.4) and 94.6% (93.0, 95.9), respectively, for psoriasis. The EMM often presented before the arthritis (uveitis 45.1% and 33.3%, and IBD 37.4% and 70%, in AS and PsA, respectively). In the multivariable model, longer diagnostic delay (≥5 years) associated with more uveitis (hazard ratio [HR] 4.01; 95% CI: 3.23, 4.07) and IBD events (HR 1.85; 95% CI: 1.28, 2.67) in AS. Diagnostic delay was not significantly associated with uveitis (HR 1.57; 95% CI: 0.69, 3.59) or IBD events (HR 1.59; 95% CI: 0.39, 6.37) in PsA. CONCLUSION: EMMs are more prevalent in AS than PsA and often present before the onset of the articular disease. A longer diagnostic delay is associated with the 'de novo' appearance of uveitis and IBD in AS, highlighting the need to enhance diagnostic strategies to shorten the time from first symptom to diagnosis in SpA.

Value of Chest X-Ray and Chest Computed Tomography for Systemic Sarcoidosis Diagnosis in Undifferentiated Uveitis.

BACKGROUND: To evaluate the contribution of chest X-ray and chest CT for the diagnosis of sarcoid uveitis. METHODS: Retrospective study on consecutive patients with uveitis of unknown etiology, who underwent both chest X-ray and CT during uveitis diagnosis workup in a tertiary French university hospital. RESULTS: A total of 914 patients were included. Systemic sarcoidosis was identified in 23.1%. The probability of discordance between chest X-ray and CT increased with age at diagnosis (p < 0.001). In patients 30 years of age and younger, the probability of discordance was 5% or less, and 0.8% if the ACE level was normal. After 78.3 years of age, the probability of discordance was 20% or more. CONCLUSION: We recommend not to perform CT in patients under 30 years of age with a normal chest X ray and ACE level, and suggest performing chest CT first in the elderly.
