Aspectos clínicos e tratamento de pacientes com tuberculose ocular presumida em centro de referência de São Paulo, Brasil. Estudo retrospectivo / Clinical description and treatment of patients with presumed ocular tuberculosis in São Paulo, Brazil. Retrospective study

Resumo Objetivo: Descrever aspectos clínicos e esquema terapêutico dos pacientes com tuberculose ocular presumida tratados em um centro de referência em tuberculose de São Paulo. Métodos: Estudo retrospectivo descritivo. O teste exato de Fisher foi realizado quando apropriado. Resultados: A queixa mais comum foi baixa acuidade visual (83,1%), seguida por dor ocular generalizada (25,3%) e visão turva (22,8%). A uveíte posterior foi a apresentação mais comum (35,7%). O tratamento consistiu no esquema atualmente recomendado de rifampicina, isoniazida, pirazinamida e etambutol (RHZE). A prednisona oral foi incluída no tratamento de 37 pacientes, para tratamento da inflamação aguda, embora não tenha diminuído a prevalência de complicações crônicas, em comparação com a recuperação completa (p = 0,1). O diagnóstico precoce (<70 dias) foi associado a maiores taxas de recuperação total (p = 0,005). Não houve significância estatística quando se comparou a terapia de 6 a 9 meses (p = 0,7). Conclusão: A uveíte tuberculosa pode ser tratada por uma terapia com duração de seis meses. Um breve curso de esteroides melhora os sintomas agudos, embora não reduza as complicações a longo prazo.

Abstract Purpose: To analyze and describe the therapy used in presumed ocular tuberculosis in a referral center in São Paulo, Brazil. Methods: Retrospective, descriptive study. Fisher's exact test was performed when appropriate. Results: The most common complaint was low visual acuity (83.1%), followed by generalized ocular pain (25.3%) and blurred vision (22.8%). Posterior uveitis was the most common presentation (35.7%). Treatment consisted of the currently recommended association of rifampin, isoniazid, pyrazinamide, ethambutol (RHZE) regimen. Oral prednisone was included in the treatment of 37 patients for acute inflammation, although it did not significantly decrease the prevalence of chronic complications compared to full recovery (p = 0,1). Early diagnosis (< 70 days) was associated with higher rates of full recovery (p = 0.005). No statistical significance was observed when comparing 6 to 9-month therapy (p = 0.7). Conclusion: Tuberculous uveitis can be treated with a 6-month duration RHZE therapy. A brief course of steroids may improve acute symptoms, although it did not reduce long-term disabilities.

Unilateral acute posterior multifocal placoid pigment epitheliopathy in a patient with a strongly positive purified protein derivative test / Epiteliopatia pigmentar placóide multifocal posterior aguda unilateral na presença de reação forte positiva para o teste tuberculínico

ABSTRACT A 27-year-old man presented with a complaint of decreased visual acuity in the right eye. Best-corrected visual acuity was 20/60 in the right eye and 20/20 in the left eye. Right eye fundoscopy revealed mild vitritis, multifocal yellowish lesions, and macular serous retinal detachment. Left eye evaluation was normal. Acute posterior multifocal placoid pigment epitheliopathy was diagnosed in the right eye. Complementary exams revealed a strong reaction to the Mycobacterium tuberculosis purified protein derivative test, thus treatment for tuberculosis was initiated. Baseline fluorescein angiography of the right eye revealed early hypofluorescence and late staining of the lesions. Optical coherence tomography of the right eye demonstrated the accumulation of subretinal and intraretinal fluid associated with cystoid macular edema. During follow-up, the retinal fluid and cysts disappeared, which was followed by disorganization of foveal interdigitation and ellipsoid zones. This is the second described case of unilateral acute posterior multifocal placoid pigment epitheliopathy in a patient with a strong positive result to the M. tuberculosis purified protein derivative test.

RESUMO Um homem de 27 anos apresentou uma queixa de diminuição da acuidade visual no olho direito. A acuidade visual melhor corrigida foi 20/60 no olho direito e 20/20 no olho esquerdo. A fundoscopia do olho direito revelou vitreíte leve, lesões amareladas multifocais e descolamento seroso da retina em região macular. A avaliação do olho esquerdo foi normal. Epiteliopatia pigmentar placóide multifocal posterior aguda foi diagnosticada no olho direito. Os exames complementares revelaram forte reação ao teste do derivado proteico purificado Mycobacterium tuberculosis, iniciando terapia antibiótica contra tuberculose. A angiografia fluoresceínica basal do olho direito revelou hipofluorescência precoce e tardia das lesões. A tomografia de coerência óptica do olho direito demonstrou fluído sub- e intrarretiniano associado a edema macular cistóide. Durante o seguimento, os fluídos e cistos retinianos desapareceram, seguido da desorganização das zonas de interdigitação e elipsóide em região foveal. Este é o segundo caso descrito de epiteliopatia pigmentar placóide multifocal posterior aguda unilateral em um paciente com um forte resultado positivo para o teste tuberculínico.

Anterior uveitis as a manifestation of ocular tuberculosis / Uveíte anterior como manifestação de tuberculose ocular

ABSTRACT Tuberculosis (TB) is an infectious disease of great magnitude in the world. Of patients with extrapulmonary disease, ocular manifestations are rare but among reported cases the most common ocular manifestation is uveitis. The diagnosis of ocular TB should be made as early as possible so that treatment is initiated and the risks of ocular complications are minimized. The objective of this study is to report an ocular TB case that presented as anterior uveitis. A 52-year-old female patient, a nursing technician at a large hospital, presented a history of low visual acuity associated with myiodesopsia for 4 days. Her ophthalmologic history included an iridotomy due to narrow angle in both eyes. On examination, the best corrected visual acuity was 20/100, right eye, and 20/80, left eye. Among the most significant ocular alterations were granulomatous keratic precipitates, anterior chamber reaction, flare and light vitreitis, corresponding to anterior uveitis. Based on clinical history and ophthalmologic examination, tests were ordered that corroborated the diagnosis of ocular TB. Thereafter, antituberculous therapy was instituted with a good response in 15 days, including improvement in visual acuity. The patient was followed-up by ophthalmology and infectology. Intraocular TB should be considered in the differential diagnosis of any type of intraocular inflammation. The diagnosis of presumed ocular TB is a clinical challenge with the diagnosis modalities currently available. The faster the onset of treatment, the better the visual prognosis of the affected patient.

RESUMO A tuberculose (TB) é uma doença infecciosa de grande magnitude no mundo. Dos pacientes com doença extrapulmonar, as manifestações oculares são raras, mas entre os casos relatados, a manifestação ocular mais comum é a uveíte. O diagnóstico de TB ocular deve ser feito o mais precoce possível para que o tratamento seja iniciado e os riscos de complicações oculares sejam minimizados. O objetivo deste estudo é relatar um caso de TB ocular que se apresentou como uveíte anterior. Uma paciente do sexo feminino, 52 anos, técnica de enfermagem de um hospital de grande porte, apresentou história de baixa acuidade visual associada à miodesopsia por 4 dias. Sua história oftalmológica incluía uma iridotomia devido ao ângulo estreito em ambos os olhos. No exame, a melhor acuidade visual corrigida foi 20/100, olho direito, e 20/80, olho esquerdo. Dentre as alterações oculares mais significativas, destacam-se precipitados ceráticos granulomatosos, reação de câmara anterior, flare e vitreíte leve, correspondendo à uveíte anterior. Com base na história clínica e no exame oftalmológico, foram solicitados exames que corroboram o diagnóstico de TB ocular. Posteriormente, a terapia antituberculosa foi instituída com uma boa resposta em 15 dias, incluindo melhora na acuidade visual. A paciente foi acompanhada pelas especialidades: oftalmologia e infectologia. A TB intraocular deve ser considerada no diagnóstico diferencial de qualquer tipo de inflamação intraocular. O diagnóstico presumível de tuberculose ocular é um desafio clínico com as modalidades de diagnóstico atualmente disponíveis. Quanto mais rápido o início do tratamento, melhor o prognóstico visual do paciente afetado.

The impact of ocular tuberculosis on vision after two months of intensive therapy

ABSTRACT Tuberculosis is an infectious disease of global importance with major economic and social burden accounting for 25% of all avoidable deaths in developing countries. Extrapulmonary involvement may occur either in association with clinically apparent pulmonary tuberculosis or in isolation. This cross-sectional descriptive study aimed to evaluate the impact of ocular tuberculosis in visual acuity at baseline and after two months of intensive anti-tuberculous therapy. A sample of 133 pulmonary tuberculosis patients, seven disseminated tuberculosis, and three pleural tuberculosis patients was evaluated. All patients underwent routine ophthalmic evaluation, including assessment of visual acuity, biomicroscopy, applanation tonometry, indirect ophthalmoscopy, and fluorescent angiography as appropriate. None of the patients had impaired visual acuity due to tuberculosis. A rate of 4.2% (6/143) of ocular involvement was found. None of the patients with ocular involvement were HIV-infected. Of the six patients with ocular involvement, five met the diagnostic criteria for probable and one for possible ocular lesions. As for the type of ocular lesions, two patients had bilateral findings: one had sclerouveitis and the second had choroidal nodules. The other four patients presented with unilateral lesions: peripheral retinal artery occlusion in the right eye (one case), choroidal nodules in the left eye (one case), and choroidal nodules in the right eye (two cases). Patients progressed favorably after two month of intensive therapy, with no significant reduction in vision.

Isolated posterior scleritis associated with tuberculosis / Esclerite posterior isolada associada à tuberculose

ABSTRACT Ocular tuberculosis (TB) is considered to be rare, although its incidence has varied widely over time and in different populations. Latent TB is diagnosed when a person is infected with Mycobacterium tuberculosis but does not have active TB. During the last decade, interferon-gamma release assay tests have been developed that allow identification of patients with latent TB infection with better specificity than the tuberculin skin test and can differentiate between infection and prior vaccination. Although rare, tuberculous scleritis should be considered in the differential diagnosis of posterior scleritis. Here we describe a patient with posterior scleritis and severe visual loss associated with latent TB without uveitis, anterior scleritis, keratitis, or any other previous ocular disease history. The patient responded well to a combined treatment of antitubercular therapy and oral corticosteroids.

RESUMO A tuberculose (TB) ocular foi considerada rara, embora a sua incidência tenha variado significativamente ao longo do tempo e nas diferentes populações. A TB latente é diagnosticada quando alguém é infetado com Mycobacterium tuberculosis sem possuir doença ativa. Durante a última década, testes tendo por base interferon gamma release assay foram desenvolvidos, permitindo a identificação de pacientes com infeção por tuberculose latente com maior especificidade que o teste tuberculínico e diferenciar infeção e vacinação prévia. Embora rara, a esclerite tuberculosa deve ser tida em consideração no diagnóstico diferencial de esclerite posterior. Reportamos um paciente com esclerite posterior e baixa grave de acuidade visual associada a TB latente, sem uveíte, esclerite anterior, ceratite ou história de doença ocular prévia. O paciente respondeu favoravelmente a um tratamento combinado de fármacos antituberculose e corticoides orais.

Granuloma macular por tuberculose sem manifestação pulmonar / Macular granuloma due to tuberculosis without pulmonary symptoms

Tuberculose é uma doença infecciosa causada pelo Mycobacterium tuberculosis, também conhecido como bacilo de Koch. O principal sítio de acometimento é o pulmonar, porém o bacilo pode disseminar-se por via linfo-hematogênica para outros órgãos, dentre eles o olho. A incidência de tuberculose ocular é de 1 a 2% dos casos extrapulmonares. Os autores apresentam um caso clínico de um paciente do sexo feminino de 28 anos que procura atendimento médico devido à redução da acuidade visual em olho esquerdo há 7 dias. Apresentava a melhor acuidade visual corrigida no olho acometido de 20/200 e no olho contralateral de 20/20. Na fundoscopia era evidenciado um granuloma em área macular do olho esquerdo, com edema e hemorragia intrarretiniana adjacente. Após investigação diagnóstica, a paciente foi tratada com esquema antibiótico para tuberculose durante 6 meses, obtendo regressão do granuloma e melhora da acuidade visual deste olho para 20/50.

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis.The main site of involvement is the lung, but the bacillus may spread by hematogenous/lymph systems to other organs, including the eye.The incidence of ocular TB is 1-2% of extra-pulmonary cases. The authors present a case of a 28 years old female patient seeking medical care due to reduction of visual acuity in the left eye for 8 days. She had the best corrected visual acuity in the affected eye of 20/200, and the opposite eye was 20/20. At fundoscopy was shown a granuloma in the macular area of the left eye, with retinal edema and hemorrhage. After diagnostic investigation the patient was treated with antibiotic therapy for tuberculosis during 6 months, obtaining lesion regression and visual acuity improvement to 20/50.

Tuberculose intraocular / Intraocular tuberculosis

A Tuberculose (TB) é uma doença infecciosa causada pelo Mycobacterium tuberculosis (Mtb), que acomete principalmente os pulmões. Ela pode acometer qualquer parte do olho, porém o local mais acometido é a úvea. A incidência de envolvimento de TB ocular e em outros sítios é de 1 por cento a 2 por cento. Alguns autores descrevem várias alterações intraoculares, tendo apresentações clínicas das mais variadas, uveíte anterior, posterior, intermediária e panuveíte. Nesta revisão iremos tratar especificamente de TB intraocular, discutindo sobre as diversas manifestações, diagnóstico e tratamento.

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis (Mtb), which attacks mainly the lungs. This disease can also attack any part of the eye; however, the more attacked ocular site is the uvea. The incidence of involvement of ocular and other sites TB is of 1 percent to 2 percent. Some authors describe several intraocular alterations, presenting the most varied clinical presentations, such as anterior, posterior, and intermediate uveitis, as well as panuveitis. In this revision, we will approach specifically the intraocular TB, discussing about its different manifestations, diagnosis, and treatment.

Efusão uveal associada à tuberculose presumida: relato de caso / Uveal effusion associated with presumed tuberculosis: case report

Os autores relatam a rara associação de efusão uveal e tuberculose ocular presumida em paciente do sexo masculino que apresentou melhora clínica com o uso sistêmico de prednisona 40 mg/d e rifampicina 600 mg/d. Descrevem, ainda, aspectos relevantes da efusão uveal, como etiopatogenia, evolução da doença, diagnóstico diferencial e tratamento, por meio de revisão da literatura.

The authors report a rare association of uveal effusion with presumed ocular tuberculosis in a male patient who presented clinical improvement with the systemic use of prednisone 40 mg/d and rifampicin 600 mg/d. In addition, relevant aspects of the uveal effusion such as the pathogenesis, evolution of the disease, differential diagnosis and treatment are described through a revision of the literature.

Tuberculosis ocular / Ocular tuberculosis

Tuberculosis (TB) is considered a public health problem in several countries. This disease is classified as either pulmonary or extrapulmonary. Within the extrapulmonary disease, ocular involvement is uncommon but it is important to recognize it because its incidence has been reported up to 1 percent. Ocular TB cases can be divided in primary and secondary. These manifestations can be caused by an active infection that invades the eye or by an immunologic reaction of delayed hypersensitivity in absence of the infectious agent. The most common clinical presentations are: chronic anterior uveitis, choroiditis and sclerokeratitis. Despite the existence of highly sensitive molecular diagnostic techniques, the diagnosis of ocular tuberculosis continues to be presumptive, based upon clinical presentation, systemic evaluation and response to treatment. For the treatment we use four drugs during a two month period (isoniazid, rifampin, pyrazinamide and ethambutol) and two drugs for four additional months.

La tuberculosis (TBC) es considerada un problema de salud pública en varios países del mundo. Esta enfermedad se clasifica en pulmonar y extra pulmonar. Dentro de la forma extra pulmonar, el compromiso ocular es poco común, pero es importante conocerlo ya que su incidencia puede llegar hasta 1 por ciento. Los casos de TBC ocular se dividen en primarios y secundarios. Las manifestaciones oculares pueden ser causadas por una infección activa que invade el ojo o por una reacción inmunológica de hipersensibilidad retardada, en ausencia del agente infeccioso. Las presentaciones más comunes son: uveítis anterior crónica, coroiditis y esclero-queratitis. A pesar de la existencia de herramientas moleculares altamente sensibles, el diagnóstico de TBC ocular continúa siendo presuntivo, basándose en la presentación clínica, evaluación sistémica y la respuesta terapéutica. Para el tratamiento se utilizan cuatro fármacos por dos meses (isoniacida, rifampicina, pirazinamida y etambutol) y dos fármacos por cuatro meses adicionales.

Tumor vasoproliferativo associado à tuberculose ocular presumida: relato de caso / Vasoproliferative tumor associated with presumed ocular tuberculosis: case report

OBJETIVO: Descrever um caso de tumor vasoproliferativo associado à tuberculose ocular tratado com crioterapia e injeção de triancinolona intravítrea. DESENHO DO ESTUDO/PACIENTES E MÉTODOS: Relato de caso intervencional. Paciente do sexo feminino, 42 anos, referia inflamação do olho direito havia 1 ano, não diagnosticada, tratada com prednisona oral por 30 dias. Relatava baixa visão com o olho direito (OD) desde a infância. Negava antecedentes pessoais e familiares. Ao exame ocular, apresentava acuidade visual menor que 20/400 com o OD. Não apresentava alterações à biomicroscopia e a pressão intra-ocular era normal em ambos os olhos. A fundoscopia do OD mostrava lesão vascularizada, elevada, associada ao descolamento seroso e exsudatos duros, localizada na periferia inferior da retina. A lesão era cercada por extensa área de pontos de hiperplasia do epitélio pigmentar. A mácula apresentava diminuição do reflexo foveal. No exame de ultra-som ocular, a lesão apresentava altura igual a 2,25mm e consistência sugestiva de lesão vascularizada. Foram solicitados exames sorológicos, hemograma, RX tórax e PPD. Os exames foram normais, com exceção do PPD, considerado forte reator. A paciente foi encaminhada ao infectologista, que diagnosticou tuberculose após exame de pesquisa de BK no escarro. Em face do quadro clínico, foi feito o diagnóstico de tumor vasoproliferativo da retina associado à tuberculose ocular presumida. Iniciou-se o tratamento com esquema tríplice (rifampicina, isoniazida e piridoxina). Optou-se por tratar o tumor com crioterapia e injeção intravítrea de triancinolona (4 mg/ml). Após 30 dias, a paciente apresentava diminuição do descolamento seroso e áreas atróficas na lesão tumoral. O aspecto angiofluoresceinográfico mostrava algumas áreas de enchimento precoce da trama vascular com discreto extravasamento tardio do contraste, sem áreas de oclusão capilar. A maior parte da lesão apresentava hipofluorescência por bloqueio (proliferação...

PURPOSE: To describe a case of vasoproliferative tumor associated with presumed ocular tuberculosis treated with cryotherapy and intravitreal triamcinolone injection. STUDY DESIGN/PATIENT AND METHODS: Interventional case report. A 42-year-old female patient reported inflammation of the right eye 1 year ago, treated with oral prednisone for 30 days. She referred blurred vision in the right eye since childhood. Ophthalmologic examination showed 20/400 visual acuity in the right eye. Biomicroscopy and intraocular pressure were normal. Fundus examination showed vascularized elevated lesion, associated with serous retinal detachment and hard exudates at the inferior periphery. The lesion was surrounded by extensive area of hyperplastic retinal pigment epithelium. The macula showed attenuation of the foveal reflex. Ocular ultrasound showed a 2.25 mm height vascularized lesion. Serologic examination, hemogram and thorax RX were normal. PPD was considered strong reactor and tuberculosis was diagnosed after positive BK research. Considering the clinical aspects, the ocular diagnosis was vasoproliferative tumor associated with presumed ocular tuberculosis. Treatment with rifampicin, isoniazide and pyridoxine was started. We decided to treat the ocular tumor with cryotherapy and intravitreal triamcinolone injection (4 mg/ml). After 30 days, serous detachment was smaller and the tumor showed atrophic areas. Fluorescein angiography showed areas of vascular hyperfluorescence with slight extravasation and areas of blocked fluorescence due to RPE hyperplasia. Secondary vasoproliferative tumors are retinal glial proliferations and are associated with many ocular conditions that affect retina and choroid. Because of the great number of associated complications, with important visual loss, vasoproliferative tumors should be treated at the moment of diagnosis. Treatment of choice is cryotherapy. Intravitreal triamcinolone can be used as adjuvant treatment...

The treatment of ocular tuberculosis: a survey of published literature.

With an expanding awareness of ocular tuberculosis, ophthalmologists are increasingly required to participate in the care of these patients. We conducted a survey of published ophthalmic literature to identify whether the regimens of antitubercular medications prescribed conform to current guidelines. A Medline search for publications (1995-2005) was done and the data were systematically analyzed with respect to demographic features, clinical findings and the antitubercular therapy prescribed. Of the 34 papers (82 patients) available, 33 papers described the prescribed antitubercular therapy. Eighteen papers (54.5%, 46 patients) conformed to guidelines versus 15 papers (45.4%, 32 patients) did not, suggesting that a large proportion of papers do not conform to current guidelines. Wider dissemination of therapeutic guidelines is necessary to encourage rational therapy and minimize therapeutic failures, drug resistance or relapse.

A Case of Primary Lid Tuberculosis after Upper Lid Blepharoplasty

Primary lid tuberculosis after lid surgery is a very rare condition and is likely caused by the introduction of bacilli through epithelial injury. Secondary infection, due to direct hematogenous spread or contiguous spread from adjacent structures are more common presentations of lid tuberculosis. The authors experienced a case of primary lid tuberculosis occurring in a 19 year old female after blepharoplasty for making a eyelid crease. Her upper lid skin showed a reddish and non-tender mass lesion measured 3x1 cm, which was diagnosed as the tuberculosis through typical histopathological findings (caseous necrosis), acid-fast bacilli stain and PCR, and treated with anti-tuberculosis medications.
