Causes and characteristics of uveitis cases at a reference university hospital in Rio de Janeiro, Brazil / Causas e características das uveítes em hospital universitário de referência no Rio de Janeiro, Brasil

ABSTRACT Purpose: The aim of this study was to describe the epidemiological profile of uveitis cases treated at University Hospital Clementino Fraga Filho and to identify the presentation pattern of intraocular inflammation on the basis of clinical, anatomical, etiological, and demographic criteria. Methods: A retrospective study was conducted using data from the medical records of 408 patients with active disease who attended the ophthalmology service between March and October 2018. Age, sex, visual acuity at the time of diagnosis, anatomical and etiological diagnoses, the clinical aspect, and the main symptoms reported during anamnesis were described. Results: Of the 408 patients in the study, 52% were male and 48% were female. The patients' mean age was 42 years, and most (84%) were between 19 and 64 years old. Anterior uveitis was observed in 37.75% of the patients; posterior uveitis, in 49.75%; panuveitis, in 4.66%; and intermediate uveitis, in 3.43%. Only 18 patients (4.41%) presented with scleritis. Of the 390 patients with anatomical classifications, 76% had known etiologies, with the most prevalent diagnoses being toxoplasmosis (35.4%), followed by juvenile idiopathic arthritis (6.4%), ankylosing spondylitis (5.9%), and syphilis (4.9%). Infectious uveitis corresponded to 49.7% of the patients, while 26.6% of the cases were of noninfectious origin. Anterior uveitis had the highest number of cases classified as idiopathic (49.4%). In the cases of posterior uveitis, the etiology was established 94% of the time. The most frequent symptoms were ocular pain (71.8%) and blurring vision (56.8%). Conclusions: The present study confirmed the historical importance of infectious uveitis in our population, especially ocular toxoplasmosis. Uveitis appears to have no predilection for sex but mainly affects young people of working age, thus generating social and economic consequences. Despite the evolution of diagnostic methods, idiopathic uveitis remains one of the major etiologies. Epidemiological studies point to different presentation patterns of uveitis in different populations, but these may reflect the distinct characteristics of each institution.

RESUMO Objetivo: Descrever o perfil epidemiológico das uveítes atendidas no Hospital Universitário Clementino Fraga Filho - UFRJ. Identificando o padrão de apresentação da inflamação intraocular a partir de critérios clínicos, anatômicos, etiológicos e demográficos. Métodos: Estudo retrospectivo, com base em prontuários de 408 pacientes com doença ativa, atendidos no serviço de oftalmologia no período de março a outubro de 2018. Foram descritos a idade, sexo, acuidade visual no momento do diagnóstico, diagnóstico anatômico e etiológico, aspecto clínico, além dos principais sintomas relatados durante a anamnese. Resultados: Dos 408 pacientes do estudo, 52% eram do sexo masculino e 48% do feminino. A idade média dos pacientes foi de 42 anos, a maioria (84%) entre 19 e 64 anos. Uveíte anterior foi observada em 37,75% dos pacientes, uveíte posterior em 49,75%, panuveíte em 4,66% e uveíte intermediária em 3,43%; apenas 18 pacientes (4,41%) apresentaram diagnóstico de esclerite. Dos 390 pacientes com classificação anatômica, a etiologia foi determinada em 76% deles, com os diagnósticos mais prevalentes sendo Toxoplasmose (35,4%), artrite idiopática juvenil (6,4%), espondilite anquilosante (5,9%) e sífilis (4,9%). ) A uveíte infecciosa correspondeu a 49,7% desses pacientes, enquanto 26,6% eram de origem não infecciosa. A uveíte anterior teve o maior número de casos classificados como idiopáticos (49,4%), enquanto a uveíte posterior teve a etiologia estabelecida em 94% das vezes. Os sintomas mais frequentes foram dor ocular (71,8%) e visão embaçada (56,8%). Conclusões: O presente estudo confirmou a importância histórica da uveíte infecciosa em nossa população, principalmente a toxoplasmose ocular. As uveítes parecem não ter predileção por sexo, mas afetam principalmente jovens em idade ativa, gerando consequências sociais e econômicas. Apesar da evolução nos métodos diagnósticos, a uveíte idiopática continua sendo uma das principais causas. Estudos epidemiológicos apontam para diferentes padrões de uveíte nas populações, estes podem refletir características particulares de cada instituição.

Síndrome de Blau: infiltrados subepiteliais como manifestações oftalmológicas incomuns / Blau Syndrome: subepithelial infiltrates as uncommon ophthalmologic manifestation

Resumo A Síndrome de Blau é uma doença de caráter hereditário autossômico dominante a qual também pode ocorrer de forma esporádica via mutação "de novo". Em geral, tem aparecimento precoce ainda na primeira infância e sua tríade clássica inclui artrite, dermatite e uveíte. Este trabalho visa relatar as manifestações clínicas e principalmente oftalmológicas de uma paciente diagnosticada com Síndrome de Blau com ênfase ao achado incomum de infiltrados corneanos subepiteliais, raramente descrito na literatura.

Abstract The Blau syndrome is an autosomal dominant hereditary disease which can also occur sporadically via "de novo" mutation. Overall it has early onset and its classic triad includes arthritis, dermatitis and uveitis. This paper describes clinical and mainly especially ophthalmologic manifestations of a patient diagnosed with Blau syndrome with emphasis on an uncommon finding of corneal subepithelial infiltrates, rarely described in the literature.

Resumo Objetivo: Analisar a distribuição dos casos de uveíte em pacientes atendidos no Setor de Uveíte do Serviço de Oftalmologia do Hospital Federal Servidores do Estado do Rio de Janeiro. Métodos: Estudo epidemiológico retrospectivo, transversal e descritivo pela análise de prontuários de 63 pacientes atendidos no Serviço de Oftalmologia do Hospital Federal dos Servidores do Estado do Rio de Janeiro, no Setor de Uveíte, no período de Março a Outubro de 2016. Resultados: A média de idade foi de 45,54 (±15,8), sendo 50,8% do sexo feminino e 49,2% do masculino. Uveítes anteriores corresponderam à 63,49% dos casos, intermediárias 1,58% posterior 19,04% e panuveíte 15,87%. Apenas 33,3% dos pacientes encontravam-se com processo inflamatório ativo no momento da avaliação. Cerca de 74,6% das uveítes tinham causas não infecciosas e em 12,69% não foi possível a determinação etiológica. A causa isolada mais frequente foi Espondilite Anquilosante, responsável por 28,57% dos casos. Demonstrou-se que 55,5% dos pacientes tinham acometimento bilateral e 71,14% apresentavam uveíte não granulomatosa. Conclusões: Estudos epidemiológicos que tratam de uveíte são, em geral, realizados em centros terciários de atendimento, que por vezes apresentam perfil etiológico destas inflamações intra-oculares diferente da população geral.

Clinical and epidemiological characteristics of patients with uveitis in an emergency eye care center in Brazil / Características clínicas e epidemiológicas das uveítes em um serviço de urgência oftalmológica no Brasil

Purpose: To analyze the clinical and epidemiological characteristics of patients with uveitis in an emergency eye care center. Methods: We conducted a prospective, observational study of patients with active uveitis admitted between May 2012 and July 2012 to an emergency eye care center. Results: The majority of patients were male (63.2%), with a mean age of 43.2 years; 66.2% patients were of mixed ethnicity, 22.5% were Caucasian, and 11.3% were black. Anterior uveitis was observed in 70.1% patients, posterior uveitis in 26.5%, and panuveitis in 3.4%; no patient was diagnosed with intermediate uveitis. All patients had a sudden and acute presentation. The most frequent symptoms were ocular pain (76.9%), redness (59.8%), and visual blurring (46.2%). The majority of patients had unilateral disease (94.9%) with a mean symptom duration of 6.2 days. Diffuse and anterior uveitis were associated with ocular pain (p<0.001). Scotomata and floaters were more frequent in patients with posterior uveitis (p=0.003 and p=0.016, respectively). Patients with anterior uveitis presented with better visual acuity (p=0.025). Granulomatous keratotic precipitates were more frequent in patients with posterior uveitis (p=0.038). An etiological diagnosis based on the evaluation at the emergency center was made in 45 patients (38.5%). Conclusions: Acute anterior uveitis was the most frequent form of uveitis. Initial patient evaluation provided sufficient information for deciding primary therapy and aided in arriving at an etiological diagnosis in a considerable number of patients. .

Measurement and significance of serum interferon-γ,tumor necrosis factor-α and interleukin-6 in patients with uveitis / 中华眼底病杂志

Objective To examine the levels of interferon-γ(INF-γ).tumor necrosis factor-α (TNF-α)and interleukin-6(IL-6)in serum of patients with acute uveitis before and after treatment,and to explore the possible roles of those cytokines in the initiation and progression of the u,ieitis. Methods A series of 75 patients with acute uveitis.and 30 healthy persons from our hospital were investigated.The Ievels of INF-γ,TNF-α and IL-6 in acute phase and convalescent phase were measured by the enzymelinked immunosorbent assay. Result The serum 1evels of INF-γ,TNF-α and IL-6 in acute phase were significantly higher than that of the convalescent phase and the healthy controls(F=65.805/50.418/155.381,P=0.000).A significant negative correlation was found between the serum leveis of INF-γ,TNF-α and IL-6 in acute phase with their initiaI visual acuity(r=-0.656,-0.592 and-0.653,P＜O.01).There was also a positive correlation among the serum levels of INF-γ,TNF-α and IL-6(r=0.340,0.467 and 0.338,P＜0.05). Conclusions There are high serum levels of INF-γ,TNF-α and IL-6 in patients with acute uveitis,and the cytokines levels were decreased after the treatment.The results suggested that the INF-γ,TNF-α and IL-6 involved in initiation and progression of uveitis.

Expression of costimulatory molecules on peripheral blood lymphocytes in patients with Behet's disease / 中华眼底病杂志

Objective To investigate the expression of costimulatory molecules( B7, CD28, and CTLA-4) of peripheral blood lymphocytes in patients with Behcet′s ) disease(BD). Methods Lymphocytes were obtained in 24 patients with BD and 20 healthy individuals, and the expression of CD80(B7-1), CD86(B7-2), CD28 and CTLA-4 on T and B cells were detected by direct three-color immunofluorescence flow cytometry. Results Significantly increased expression of CTLA-4 on CD4 + T cells [(3. 18?1. 18)%] was found in BD patients compared with that in controls [(1. 73?0. 66) %] ( t=-3. 722,P

Studies on the etiologies and classification of uveitis / 中华眼底病杂志

Objective To study the clinical classification and etiologies of uveitis based on 1 214 uveitis patients reffered to Zhongshan Ophthalmic Center. Methods A retrospective analysis was made on the patients with uveitis, coming from all over China between January 1996 and December 2001. All kinds of uveitis were classified according to the anatomical criteria and etiological criteria. The relevant data of these patients, such as the age at uveitis onset and sex were also analyzed. Results The total number of the patients is 1 214 (male 698, female 516), with the average age at disease onset being 34.43. Anterior uveitis, the most common type, was seen in 546 cases, accounting for 44.98% of all the patients, followed in descending order by panuveitis (530 cases, 43.66%), intermediate uveitis(78 cases, 6.43%) and posterior uveitis(60 cases, 4.94%). Etiological factors and clinical entities were identified in 703 patients, accounting for 57.91% of all the patients, and the other 511 patients were idiopathic ones. The most common types of anterior uveitis were idiopathic uveitis(316 cases, 57.88%), followed by Fuchs syndrome(85 cases) and ankylosing spondylitis(45 cases). Behcet ) disease(218 cases, 41.13%) and Vogt-Koyanagi-Harada syndrome(196 cases, 36.98%) were the most common entities in panuveitis. Neither etiological factors nor clinical entities could be identified in the patients with intermediate uveitis and those with posterior uveitis. Conclusions Uveitis occurs mostly in young and middle-aged adults. In general, a predilection was seen in the male as compared with the female in the development of uveitis. Idiopathic anterior uveitis, Behcet ) disease and Vogt-Koyanagi-Harada syndrome are the most common entities of uveitis seen in China. Classification based on etiological and anatomical factors may provide a reasonable system for the study of uveitis.

Effects of ?-interferon on the expression of costimulatory molecules and Fas/FasL in human retina / 中华眼底病杂志

Objective To investigate the effects of ?-interferon (IFN-? on the expression of costimulatory molecules B7-1 (CD80) and B7-2 (CD86) and Fas/FasL in human retina. Methods Nine human eyes were obtained from the eye-bank of Zhongshan Ophthalmic Center. Six eyes were used for making retinal wholemounts, and 12 retinal wholemounts from each eye were put into the 24-hole culture board which had 2ml DMEM/F12 culture medium in each hole. The wholemounts were divided into 3 groups whose concentration of IFN-? was 0, 200, and 1 000 U/ml respectively. After cultured in 37℃ culture box (95%O2,5%CO2) for 24 hours, the expressions of B7-1 (CD80), B7-2 (CD86), and Fas/FasL on these retinal wholemounts were detected by immunohistochemical method. The retinal wholemounts from 3 healthy people were detected by immunohistochemical method as the control. Results Expression of FasL but not B7-1, B7-2 or Fas was found in the control group, while the expression of B7-1, B7-2 and Fas and increased expression of FasL were found after cultured with IFN-?. Conclusion IFN-? may be involved in the occurrence of ocular immune response and induction of apoptosis via the stimulation of expression of costimulatory molecules and Fas/FasL, which plays an important role in the activation of T lymphocytes.
