ABSTRACT

This study aimed to investigate the serum levels of the cytokine TNF-α and its soluble receptors (sTNFR1 and sTNFR2) in patients with toxoplasmosis retinochoroidits (TR) and controls. 37 patients with TR and 30 subjects with positive serology for toxoplasmosis but without history and signs of uveitis were included in this study. Serum concentrations of TNF-α, sTNFR1, and sTNFR2 were determined by ELISA. Serum concentrations of TNF-α and sTNFR1 were similar in controls (mean ± SD median values; 56.57 ± 141.96 and 504.37 ± 163.87, respectively) and TR patients (mean ± SD values, 121.62 ± 217.56 and 511.15 ± 189.30, respectively). Serum concentrations of sTNFR2 were higher in the uveitis group when compared to the control group (respectively, mean ± SD values, 1734.84 ± 379.32 and 1442.75 ± 309.47; p=0.002). There was no association between the serum levels of the molecules and the time of first symptoms, severity of vitreous haze, size or localization of active lesions, levels of visual acuity, and presence of vasculitis. These results suggest that TR is associated with changes in the circulating levels of inflammatory biomarkers, but they are not correlated with local/ocular signs.

ABSTRACT

OBJETIVOS: Documentar características clínicas, associações sistêmicas, tratamento e evolução de 23 pacientes com esclerite posterior, examinados no serviço de uveítes da Universidade Federal de Minas Gerais. MÉTODOS: Revisão de todos os pacientes com esclerite atendidos neste serviço, de 1999 até 2006, para identificar aqueles com esclerite posterior. Identificados 23 pacientes, registrados e analisados os dados com relação aos sinais e sintomas oculares, visão, alterações na ecografia, manifestações sistêmicas, tratamento e evolução. RESULTADOS: Dezesseis pacientes do sexo feminino e 7 do sexo masculino com média de idade de 44,7 anos. Esclerite posterior ocorreu associada à esclerite anterior em 10 pacientes, envolvimento unilateral em 17 pacientes e, bilateral simultâneo, em 6 pacientes. Esclerite posterior associada à doença sistêmica ocorreu em 8 pacientes (síndrome de Cogan, tuberculose, granulomatose de Wegener, herpes simples e zoster, aspergilose, retocolite-ulcerativa e sarcoidose). A principal queixa foi dor ocular seguida de embaçamento visual e o sinal fundoscópico que predominou foi o descolamento seroso de retina. O achado mais comum na ecografia foi espessamento da parede escleral observado em 18 pacientes e a principal forma de tratamento, o uso de corticóide sistêmico. Somente 4 pacientes necessitaram de imunossupressor. CONCLUSÃO: Esclerite posterior é doença de difícil diagnóstico e pode ser potencialmente devastadora. Análises estatísticas são incapazes de revelar outras características específicas da esclerite posterior, características clínicas dos pacientes e evolução da doença que poderiam ajudar na identificação dos casos com maior risco de perda visual ou com maior probabilidade de doença sistêmica.


PURPOSE: To document the clinical features, systemic association, treatment and evolution of 23 patients with posterior scleritis evaluated in the Uveitis service of the Federal University of Minas Gerais. METHODS: 23 patients were identified with the diagnosis of posterior scleritis. Signals and symptoms, visual acuity, B-mode ultrasonography signals, systemic associations, treatment and evolution were described and analyzed. RESULTS: Sixteen patients were female and seven were male with mean age of 44,7 years. Posterior scleritis occurred in association with anterior scleritis in 10 patients, unilateral involvement in 17 patients and simultaneous bilateral involvement in 6 patients. Posterior scleritis in association with systemic disease occurred in 8 patients (Cogan's syndrome, TBC, Wegener, Herpes simplex and Zoster, Apergilosis, inflamatory bowel disease and Sarcoidosis). The main symptoms were ocular pain and decrease of visual acuity and the main signal was retinal serous detachment. Increase of thickness choroidal tissue was the main signal in B-mode ultrasonography in 18 patients and the principal kind of treatment was the use of systemic corticosteroids. Only 4 patients required systemic immunosuppressive drugs. CONCLUSIONS: Posterior scleritis still represents a diagnostic challenge and is often associated with life threatening systemic disease and vision threatening ocular complications. Knowledge of posterior scleritis may aid in determining timely and accurate diagnosis and treatment of both ocular and any systemic conditions associated, thus decreasing morbidity and mortality. Elevated suspicion rate is always required to detect this condition.

ABSTRACT

OBJETIVOS: Documentar características clínicas, associações sistêmicas, tratamento e evolução de 100 pacientes com esclerite, examinados no serviço de uveítes da Universidade Federal de Minas Gerais. PACIENTES E MÉTODOS: Identificados 100 pacientes com esclerite, registrados e analisados dados com relação às queixas dos mesmos, sinais oculares, visão, alterações ecográficas, manifestações sistêmicas, tratamento e evolução. RESULTADOS: Sessenta e nove pacientes eram mulheres e 31 homens. Esclerite anterior difusa e nodular ocorreu em 71 pacientes, esclerite anterior necrosante em 3, esclerite posterior em 24 e escleromalácia perfurans em 2 pacientes. Envolvimento unilateral em 79 e bilateral em 21 pacientes. A principal queixa foi dor ocular e o sinal fundoscópico predominante na esclerite posterior foi o descolamento seroso de retina. Em 13 pacientes a esclerite determinou o encontro de doença sistêmica e a principal forma de tratamento foi com droga anti-inflamatória não-esteróide oral. Dezoito pacientes precisaram de tratamento imunossupressor para o controle do quadro ocular e a incidência de complicação ocular foi de 35%. DISCUSSÃO: Esclerite é doença rara, às vezes de difícil diagnóstico e potencialmente devastadora, todos os esforços devem ser necessários para um diagnóstico rápido e correto dessa doença. O conhecimento sobre a esclerite, suas formas de apresentação, associações sistêmicas, tratamento e evolução são fundamentais para que possamos fazer este diagnóstico correto e conduzir o quadro ocular da maneira mais adequada possível tendo sempre como objetivo final o controle do quadro escleral e preservação da visão do paciente.


PURPOSE: To document the clinical features, systemic association, treatment and evolution of 100 patients with scleritis evaluated at the Uveitis Service of the Federal University of Minas Gerais. PATIENTS AND METHODS: 100 patients were identified with the diagnosis of scleritis. Signals and symptoms, visual acuity, B-mode ultrasonography signals, systemic associations, treatment and evolution were described and analyzed. RESULTS: 69 patients were female and 31 were male. Diffuse and nodular anterior scleritis occurred in 71 patients, necrotizing anterior scleritis in 3, posterior scleritis in 24 and escleromalacia perforans in 2 patients. Unilateral involvement occurred in 79 patients and bilateral involvement in 21 patients. The main symptoms were ocular pain and redness and the main signal in posterior scleritis was the serous detachment of the retina. Scleritis in association with systemic disease occurred in 35 patients and the principal kind of treatment was the use of oral NSAIDs. Only 18 patients required systemic immunosuppressive drugs. Ocular complications were detected in 35 patients. CONCLUSIONS: Scleritis may represent a diagnostic challenge and is often associated with life threatening systemic disease and vision threatening ocular complications. Knowledge of scleritis may aid in determining timely and accurate diagnosis and treatment of both the ocular and any associated systemic conditions, thus decreasing morbidity and mortality.
