Síndrome uveomeningoencefálico Vogt Koyanagi-Harada con desprendimiento de la capa bacilar de la retina / Vogt Koyanagi-Barada uveomeningoencephalic syndrome with detachment of the bacillary layer of the retina

Introducción: El síndrome de Vogt-Koyanagi-Harada pertenece a los síndromes uveomeníngeos y es una de las principales enfermedades que amenazan la visión. Se caracteriza por una uveítis bilateral que se asocia frecuentemente con manifestaciones neurológicas, auditivas y tegumentarias. Recientemente un fenotipo particular de engrosamiento macular se ha descrito como desprendimiento bacilar asociado a esta enfermedad. Objetivo: Describir el desprendimiento bacilar de la retina mediante la tomografía de coherencia óptica de dominio espectral en un caso de Vogt Koyanagi Harada en fase uveítica. Presentación de caso: Paciente femenina de 46 años de edad atendida en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer" con disminución de agudeza visual en ambos ojos y panuveitis bilateral. Fue diagnosticada con síndrome de Vogt-Koyanagi-Harada en su fase uveítica aguda con presencia de manifestaciones neurológicas y desprendimiento de la capa bacilar de la retina identificado mediante la tomografía de coherencia óptica de dominio espectral. Conclusiones: El síndrome de Vogt-Koyanagi-Harada aguda y el desprendimiento bacilar de la capa de la retina pueden diferenciarse de otros signos mediante la tomografía de coherencia óptica de dominio espectral. Su desaparición pudiera tener una relación con la mejoría de la agudeza visual(AU)

Introduction: Vogt-Koyanagi-Harada syndrome belongs to the uveomeningeal syndromes and is one of the major vision-threatening diseases. It is characterized by bilateral uveitis, which is frequently associated with neurological, auditory and integumentary manifestations. Recently a particular phenotype of macular thickening has been described as bacillary detachment associated with this disease. Objective: To describe bacillary retinal detachment using spectral domain optical coherence tomography in a case of Vogt Koyanagi Harada in uveitic phase. Case presentation: 46-year-old female patient attended at the Cuban Institute of Ophthalmology "Ramón Pando Ferrer" with decreased visual acuity in both eyes and bilateral panuveitis. She was diagnosed with Vogt-Koyanagi-Harada syndrome in its acute uveitic phase with presence of neurological manifestations and detachment of the bacillary layer of the retina identified by spectral domain optical coherence tomography. Conclusions: Acute Vogt-Koyanagi-Harada syndrome and bacillary retinal layer detachment can be differentiated from other signs using spectral-domain optical coherence tomography. Their disappearance could be related to the improvement of visual acuity(AU)

miRNAs: una nueva mirada de la enfermedad de Vogt-Koyanagi-Harada / miRNAs: a new look at Vogt-Koyanagi-Harada disease

Vogt-Koyanagi-Harada disease (VKH) is an autoimmune multisystemic syndrome that includes bilateral intraocular inflammation, associated with exudative retinal detachments, and systemic manifestations in the auditory, integumentary, and central nervous systems. The frequency of VKH disease in the world is variable, but in Santiago, Chile, it causes approximately 17% of non-infectious uveitis, an incidence 2 to 3-fold greater than in the USA or European countries. The evidence shows that the pathogenesis of VKH would be caused by cell-mediated autoimmunity directed against melanocytes present in the uveal tissue. CD4+ T lymphocytes (especially hyperactivity of Th17 and Th1 cells), B lymphocytes, cytokines (e.g., TGF-ß, IL-2, IL-6, IL-23 and INF-γ) and chemokines appear to play an important role in the development of VKH. Several lines of evidence support that the pathogenesis of uveitis observed in VKH involves an altered pattern of micro-ribonucleic acids (miRNA) expression, driving the loss of immunological tolerance. In this review, we discuss the evidence related to regulation and altered expression of miRNA associated with Vogt-Koyanagi-Harada and other autoimmune diseases. (AU)

Clinical profile of human T-lymphotropic virus type I: a forgotten infection in pediatrics / Perfil clínico del virus linfotrópico humano tipo I: una infección olvidada en pediatría

Summary The Human T-lymphotropic virus type 1 (HTLV-1), a retrovirus with oncogenic properties, affects around ten to twenty million people worldwide. The most common disorders associated with HTLV-1 infection are T-cell leukemia/lymphoma (ALT) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Studies have reported other clinical manifestations in HTLV-1 seropositive patients, including inflammatory disorders, co-infections with opportunistic agents, and pulmonary diseases. Objective: Here, we aim to describe a cohort of juvenile patients with confirmed HTLV-1 infection that showed clinical manifestations other than neurological symptoms. Methodology and patients: Retrospective analysis of clinical data describing background and clinical findings of 12 juvenile patients with confirmed HTLV-1 infection, attended during January 2018 to February 2020 in a pediatric referral hospital in Cali, Colombia. Results: 11 out 12 patients were from Colombia´s Pacific coast, 10 suffered from significant nutritional deficiencies. Six exhibited dermatological findings, 3 compatible with infective dermatitis. None of the cases exhibited clinical or laboratory findings suggesting ALT or HAM/TPS. Eight patients had structural lung disease assessed by chest Computed Tomography (CT) scans; 4 of them tested positive for galactomannan antigen in bronchoalveolar fluid suggesting pulmonary aspergillosis, and 2 others exhibited a positive PCR testing for tuberculosis. Three patients were diagnosed with autoimmune disorders; 1 patient with Crohn´s Diseases, 1 case of autoimmune thrombocytopenic purpura, and a patient with Vogt-Koyanagi-Harada syndrome (non-granulomatous uveitis). Conclusions: There is a broad range of clinical manifestations in pediatric HTLV-1 patients, and the clinician should consider structural pulmonary disease, opportunistic co-infections and autoimmune disorders in the diagnostic algorithm.

Resumen El Virus Linfotrópico de células T humanas tipo 1 (HTLV-1), retrovirus con propiedades oncogénicas, afecta alrededor de 10-20 millones de personas mundialmente. Las manifestaciónes más comúnmente asociadas a HTLV-1 incluyen leucemia/linfoma de células T (ALT) y mielopatía asociada a HTLV-1/ paraparesia espástica tropical (HAM/TSP). Estudios han reportado otras manifestaciones clínicas en pacientes positivos para HTLV-1, incluyendo enfermedades inflamatorias, coinfecciones con gérmenes oportunistas y enfermedad pulmonar. Objetivo: es describir clínicamente una cohorte de pacientes pediátricos con infección por HTLV-1 confirmada que presentan manifestaciones clínicas diferentes a síntomas neurológicos. Metogolodía y pacientes: Análisis retrospectivo de historia clínica describiendo procedencia y hallazgos clínicos en 12 pacientes con infección por HTLV-1 confirmada, atendidos durante el periodo de Enero de 2018 a Febrero de 2020 en un hospital pediátrico de referencia en Cali, Colombia. Resultados: Once de 12 pacientes procedían de la costa Pacífica Colombiana, 10 con deficiencias nutricionales significativas. Seis mostraron compromiso dermatológico, 3 compatibles con dermatitis infectiva. Ningún paciente presentó hallazgos clínicos o paraclínicos sugestivos de ALT o HAM/TPS. Ocho pacientes presentaron enfermedad pulmonar estructural evidenciada por TAC de tórax; 4 de ellos con antígeno galactomanan positivo en lavado broncoalveolar, sugiriendo aspergilosis pulmonar, y otros 2 resultaron con PCR positiva para tuberculosis. Tres pacientes presentaron enfermedades autoinmunes concomitantes: uno con Enfermedad de Crohn, uno con Púrpura Trombocitopénica Autoinmune, y un paciente con Síndrome de Vogt-Koyanagi-Harada. Conclusiones: Existe un amplio rango de manifestaciones clínicas en pacientes pediátricos con HTLV-1, considerando enfermedad pulmonar estructural, coinfecciones oportunistas y enfermedades autoinmunes dentro del algoritmo diagnóstico.

Vogt-Koyanagi-Harada syndrome: a discussion about resistance to corticotherapy / Vogt-Koyanagi-Harada: uma discussão sobre resistência à corticoterapia

ABSTRACT Vogt-Koyanagi-Harada (VKH) syndrome is an inflammatory condition of unknown etiology that can affect the eye. The most common ocular manifestation related to VKH is bilateral diffuse uveitis associated to exudative retinal detachment. Although these patients respond well to steroid pulse therapy, we report a case of a 44-year-old female patient presenting bilateral exudative retinal detachment and clinical diagnosis of VKH, who did not respond to the first cycle of 3-day pulse therapy with methylprednisolone. The exudation was reabsorbed only after a second cycle of steroid therapy.

RESUMO A doença de Vogt-Koyanagi-Harada é inflamatória e de etiologia desconhecida, podendo afetar o olho. A manifestação ocular mais comum relacionada à doença de Vogt-Koyanagi-Harada é a uveíte difusa bilateral associada ao descolamento exsudativo da retina. Embora esses pacientes respondam bem à pulsoterapia com esteroides, relatamos um caso de paciente de 44 anos que apresentou descolamento exsudativo bilateral da retina com diagnóstico clínico de doença de Vogt-Koyanagi-Harada que não respondeu ao primeiro ciclo de pulsoterapia de 3 dias com metilprednisolona. A exsudação apenas reabsorveu após uma segunda rodada de terapia com esteroides.

Manifestaciones cerebrales y oculares del Síndrome de Vogt-Koyanagi-Harada / Vogt-Koyanagi-Harada Syndrome Cerebral and Ocular Manifestations

El síndrome de Vogt-Koyanagi-Harada, antes conocido como síndrome uveomeningoencefálico, es una enfermedad rara, con muy pocos casos descritos en la literatura. Es una patología autoinmune infrecuente, con un compromiso multiorgánico. La resonancia magnética es importante para identificar las lesiones de la sustancia blanca periventricular, la afectación del tallo cerebral y los pedúnculos cerebrales, así como el realce paquimeníngeo y el engrosamiento difuso de la coroides. A pesar de ser una entidad poco frecuente, es importante que el radiólogo esté familiarizado con sus características en imágenes

Vogt-Koyanagi-Harada syndrome, formerly kwon as uveomeningoencephalitic syndrome, is a rare disease, with very few cases reported in the literature. It is an uncommon autoimmune entity with multi-organ involvement. Magnetic resonance imaging is important to identify periventricular white matter lesions, brain stem and brain peduncles involvement, as well as pachymeningeal enhancement and diffuse choroidal thickening. Despite being a rare entity, it is important for the radiologist be acquainted with its imaging findings

Achados audiológicos na Síndrome de Vogt-Koyanagi-Harada / Audiological findings in the Vogt-Koyanagi-Harada Syndrome

RESUMO A síndrome de Vogt-Koyanagi-Harada (SVKH) é rara, multissistêmica e autoimune. Atinge principalmente os olhos, provocando uma panuveíte crônica bilateral, porém traz afecções em outras áreas e tecidos que são ricos em melanócitos, como olhos, orelha interna, meninges e a pele. Sua origem ainda não é totalmente conhecida. Geralmente, a SVKH atinge indivíduos de origem hispânica, do Oriente Médio, indianos, nativos americanos e asiáticos. Descrição dos aspectos audiológicos acometidos pela síndrome e as possíveis intervenções fonoaudiológicas para um caso específico. Paciente de 53 anos, sexo feminino, compareceu à Clínica de Fonoaudiologia, Faculdade de Odontologia de Bauru (FOB) com queixas audiológicas e diagnóstico médico da SVKH. A paciente apresentou perda auditiva sensório-neural bilateralmente, emissões otoacústicas evocadas ausentes e queixas vestibulares de vertigem postural e desequilíbrio ao andar, bem como queixa de zumbido agudo contínuo. O caso apresentado mostrou perda auditiva sensório-neural, vertigem, zumbido e acometimento ocular bilateral. Apesar do tratamento com corticoesteroide, a perda auditiva se manteve. Desta forma, precedente à indicação do AASI, o fonoaudiólogo deve atentar-se para o acompanhamento audiológico do caso, realização ou não de tratamento medicamentoso e ocorrência de sintomas sugestivos da síndrome, favorecendo o encaminhamento para o médico e participando ativamente do processo terapêutico envolvendo a audição.

ABSTRACT The Vogt-Koyanagi-Harada syndrome (VKHS) is a rare, multisystemic and autoimmune disease. The syndrome mainly affects the eyes, followed by bilateral chronic panuveitis, however, the syndrome may also affect the melanocytes tissues, for example, the eyes, inner ear, meninges and skin. The syndrome origin mechanism is not yet completely known. Commonly, the specific ethnic groups that are affected by the VKHS are as follows: Hispanics, Asians, Indians, Native Americans and ethnic groups from the Middle East. The audiological characteristics of the syndrome and the possible audiologist interventions for a specific case will be reported. The patient was attended at the Clinic of Speech Therapy, Faculdade de Odontologia de Bauru (FOB). She is 53 years old and presented audiological complaints. She was diagnosed with VKHS by a specialist doctor. Throughout the audiologist assessment, she presented bilateral sensorineural hearing loss, absent otoacoustic evoked emissions, complaints about postural vertigo and acute tinnitus. The specific case reported presented sudden sensorineural hearing loss, vertigo, tinnitus and bilateral ocular disease. Even though drug treatment was performed, the hearing loss remained. Therefore, before the hearing aid (HA) fitting, the audiologist should perform the hearing management, investigate if the patient takes the drug treatment and the occurrence of suggestive symptoms of the syndrome. These are some points that help in the reference to the specialist doctor and the audiologist strongly participates in what concerns the hearing.

Hipoacusia en enfermedad de Vogt-Koyanagi-Harada: caso clínico y revisión de literatura / Hearing loss in Vogt-Koyanagi-Harada Disease: case report and literature review

RESUMEN La patología autoinmune de oído interno se caracteriza por presentar hipoacusia sensorioneural bilateral, asimétrica y progresiva, que responde a terapia médica, presentándose aislada o como parte de una enfermedad sistémica como la enfermedad de Vogt-Koyanagi-Harada.

We review the literature about the disease and its otologic manifestations.

Descolamento seroso de coroide como manifestação tardia da síndrome de Vogt-Koyanagi-Harada / Serous choroidal detachment in chronic stage of Vogt-Koyanagi-Harada syndrome

Resumo Relatamos um caso atípico de uma paciente de 40 anos com apresentação completa da Síndrome de Vogt-Koyanagi-Harada (SVKH) que após 17 anos do diagnóstico inicial evoluiu com descolamento seroso de coroide. A paciente procurou atendimento com queixa de dor em olho esquerdo (OE). O exame oftalmológico revelou acuidade visual (AV) igual a de movimento de mãos, à biomicroscopia foi observada reação inflamatória granulomatosa na câmara anterior, a tonometria foi igual a 0 mmhg, e a fundoscopia indevassável pela pouca midríase e turvação de meios em OE. O descolamento seroso de coroide foi avaliado através de ultrassonografia ocular. A abordagem terapeutica intituida para paciente consistiu em prednisona 1mg/kg/dia via oral, dexametasona 1mg/mL e atropina 1% colírios. A evolução do quadro foi satisfatória, com melhora da AV para 20/40, ausência de reação inflamatória em câmara anterior, normalização da pressão intraocular e resolução do descolamento seroso de coroide em OE. Concluimos que a fase crônica da SVKH, apesar da manifestação classicamente descrita ser uveíte anterior, pode ter outras apresentações e o descolamento seroso da coroide é uma rara complicação.

Abstract We report an atypical case of a 40-year-old woman with complete presentation of Vogt-Koyanagi-Harada Syndrome (VKH) who presented with unilateral serous choroidal detachment 17 years after the diagnosis. The patient complained of pain in the left eye, the ophthalmologic examination revealed visual acuity (VA) equal to hand motion; biomicroscopy revealed a granulomatous inflammatory reaction in the anterior chamber, tonometry was equal to 0 mmhg, and the fundoscopy was impracticable. Serous choroidal detachment was assessed by ocular ultrasonography. The therapeutic approach proposed for the patient consisted of prednisone 1mg / kg / day orally, dexamethasone 1mg / mL and atropine 1% eye drops. The evolution of the condition was satisfactory, with VA improvement to 20/40, absence of inflammatory reaction in anterior chamber, normalization of intraocular pressure and resolution of serous choroidal detachment in OS. We conclude that the chronic phase of VKH, although classically described as anterior uveitis, may have other presentations and the serous choroid detachment is a rare complication.

Síndrome de Vogt-Koyanagi-Harada: Avaliação da fase da doença na qual os pacientes recebem o primeiro atendimento em serviço especializado / Vogt-Koyanagi-Harada syndrome: evaluation of the disease phase in which patients receive the first specialized attendance

Resumo Objetivo: Avaliar em qual fase da síndrome de Vogt-Koyanagi-Harada (SVKH) os pacientes recebem o primeiro atendimento em serviço especializado. Métodos: Foram analisados prontuários de 14 pacientes atendidos no Setor de Uveítes do Hospital Universitário Clementino Fraga Filho da UFRJ no período de janeiro de 2014 a março de 2017. Nesta análise, foram observados o sexo, a idade, a fase da doença e a acuidade visual destes pacientes com ao menos doença provável da SVKH. Resultados: Observamos que 35,4% dos pacientes apresentavam a doença ainda na fase uveítica e que 78,5% destes pacientes apresentava acuidade visual igual ou pior que 0,05. Destes pacientes, 78,5% eram do sexo feminino e 21,5% do sexo masculino e a mediana de idades foi de 34 anos. Conclusão: Os pacientes analisados obtiveram dificuldade em ter acesso precoce a um setor especializado, afetando assim, diretamente o tratamento e prognóstico visual.

Abstract Objective: To evaluate in which phase of Vogt-Koyanagi-Harada (VKH) syndrome the patients receive the first attendance in specialized service. Methods: A retrospective study was conduted to evaluate medical records of 14 patients with VKH in the Clementino Fraga Filho University Hospital of the Federal University of Rio de Janeiro from January 2014 to March 2017. In this analysis, gender, age, stage of disease and visual acuity of these patients with at least probable VKH were recorded. Results: Of these patients, 78.5% were female and 21.5% male and the median age was 34 years. We observed that 35.4% of the patients had the disease still in the uveitic phase and that 78.5% of these patients had visual acuity equal to or worse than 0.05. Conclusion: There is a delay in the admission of these patients to a specialized sector, thus affecting directly the treatment and visual prognosis.

Síndrome de Vogt-Koyanagi-Harada en niños / Vogt-Koyanagi-Harada syndrome in children

Vogt-Koyanagi-Harada (VKH) syndrome is a systemic inflammatory disease that causes chronic and bilateral granulomatous panuveitis, usually described in adults. Objectives: To describe manifestations and complications of VKH in pediatric patients. Methods: Retrospectivedescriptive study upon patients <14 years-old with VKH, attended from January 1985 to July 2010 in three different centers. Results: A total of 17 patients (34 eyes) were studied; 9 (53%) female. The mean age was 10.8 years-old. Among extraocular manifestations; neurological (71%), dermatological (29%) and auditive (24%) signs were observed. Ocular findings included optic-disc involvement (94%), anterior uveitis (79%), choroiditis (77%), serous retinal detachment (71%) and vitritis (71%). Initial visual acuity (VA) was ≤0.05 in 47% of cases and ≥0.6 in 12% of patients. 71% presented complications: glaucoma (20 eyes), sinechiae (10 eyes), maculopathy (6 eyes) cataract (5 eyes) and ptisis bulbi (1 eyes). 35% received only corticosteroids and 65% inmunosupressive drugs. After treatment, 6% had VA ≤0.05 and 59% ≥0.6. Ten patients (59%) recurred: 30% compromising posterior pole, and 50% recurred >3 times. Conclusions: VKH in children is infrequent. It presents with optic-disc involvement and complications of posterior pole. It requires a high degree of suspicion, quick evaluation and early treatment, which include inmunosupressive and extended corticosteroid therapy. Nevertheless, a high rate of recurrence is seen among this group of patients. (AU)

Epilens membrane simulating cataract in children with uveitis: a report of three cases / Membrana epicristaliniana simulando catarata em crianças com uveíte: relato de três casos

ABSTRACTHere we present the cases of three female children, of whom two were aged 6 years and one was aged 11 years. Two of the three children had bilateral uveitis and suspected cataract and Vogt-Koyanagi-Harada (VKH) disease. The third one had uveitis and suspected cataract in one eye and sympathetic ophthalmia (SO), and had undergone penetrating keratoplasty in the fellow eye following a trauma. After controlling the inflammation, we planned to perform phacoemulsification without intraocular lens implantation. However, intraoperatively, after removing the epilens membranes, the lenses appeared clear, and therefore phacoemulsification was not performed. During follow-up, the patients did not develop cataract, and visual acuity levels ranged from 20/30 to 20/100. Fundoscopy revealed VKH disease and SO. Ophthalmologists should not always assume that patients with uveitis have cataract; a transparent lens may exist behind the epilens membrane, allowing a less aggressive therapeutic approach.

RESUMOApresentamos os casos de três meninas (duas de seis anos e uma de onze anos), com uveíte bilateral e suspeita de catarata em ambos os olhos e doença de Vogt-Koyanagi-Harada (VKH) em dois casos. No terceiro caso, oftalmia simpática e suspeita de catarata em um olho e trauma com ceratoplastia penetrante no outro olho. Após controle da inflamação, indicou-se facoemulsificação sem LIO. No per-operatório, após retirada da membrana epicristaliniana, a transparência do cristalino foi percebida, não sendo realizada a facoemulsificação. No período de acompanhamento as pacientes não desenvolveram catarata e a acuidade visual variou de 20/30 a 20/100. O exame de fundoscopia reforçou o diagnóstico de VKH e oftalmia simpática. Portanto, é muito importante que o oftalmologista esteja sempre atento quando se deparar com um caso de uveíte com suspeita de catarata, porque, por trás da membrana epicristaliniana pode existir um cristalino transparente, o que leva a uma conduta terapêutica menos agressiva.

Enfermedad de Vogt-Koyanagi-Harada y rehabilitación visual / Vogt-Koyanagi-Harada disease and visual rehabilitation

La enfermedad de Vogt-Koyanagi-Harada es una entidad infrecuente, multisistémica, de etiología desconocida, presuntamente autoinmune, caracterizada por panuveítis granulomatosa crónica bilateral y difusa, acompañada de participación tegumentaria, neurológica y auditiva, que afecta con mayor frecuencia la raza no caucasiana y, por lo general, a mujeres. Se presenta generalmente entre los 20-50 años de edad. Su incidencia varía geográficamente. Se estima que el 25 por ciento de los pacientes con esta enfermedad son ciegos legales; que el 25 por ciento puede presentar baja visión y el 50 por ciento agudeza visual mayor de 20/50. Se presenta una paciente de 50 años de edad con antecedentes de enfermedad de Vogt-Koyanagi-Harada, de 8 años de evolución, quien ha llevado tratamiento con antinflamatorios esteroideos sistémicos e inmunosupresores, así como terapia de apoyo con antinflamatorios esteroideos tópicos y ciclopléjicos. Acudió a la consulta de baja visión y se le realizó examen oftalmológico completo, estudios complementarios y se rehabilitó mediante el uso de ayudas ópticas y no ópticas para lograr el mayor aprovechamiento de su resto visual(AU)

Vogt-Koyanagi-Harada (VKH) is a rare, multisystemic, allegedly autoimmune disease of unknown etiology. It is characterized by chronic bilateral granulomatous and diffuse panuveitis, accompanied by tegumentary, neurological and hearing impairments that often affect the non-Caucasians and usually women. It usually occurs in the 20-25 years age group and its incidence varies with the geographic location. It is estimated that 25 percent of the patients with this disease are legally blind, the other 25 percent may have low vision and 50% present with visual acuity over 20/50. There is a 50 years-old patient with a history of Vogt - Koyanagi - Harada disease for 8 years. He had been treated with systemic steroid anti-inflammatory drugs and immunosuppressive therapy as well as supporting therapy with topical and cycloplegic steroid anti-inflammatories. The patient had gone to the low vision service looking for rehabilitation. He was performed a complete eye examination, supplementary studies and he was finally rehabilitated through the use of optical and non-optical aids in order to maximize his remaining vision(AU)

Análise integrada de parâmetros clínicos, estruturais e funcionais nas fases aguda e não aguda da doença de Vogt-Koyanagi-Harada: estudo longitudinal / Integrated analysis of clinical, structural and functional parameters in the acute and non-acute phases of Vogt-Koyanagi-Harada disease: a prospective study

OBJETIVO: Descrever prospectivamente o curso da doença de Vogt-Koyanagi-Harada (DVKH) com integração de parâmetros de atividades clínicos, estruturais e funcionais. MÉTODOS: Foram incluídos pacientes com diagnóstico da DVKH na fase aguda (parte I) e não aguda (tempo de doença maior que 12 meses; parte II). Os pacientes na fase aguda receberam tratamento inicial padronizado com pulsoterapia de metilprednisolona seguido de corticoterapia oral em doses lentamente regressivas, pelo período de 15 meses. As avaliações consistiram em exame clínico, retinografia, angiografias com fluoresceína (AGF) e indocianina verde (AIV) e tomografia de coerência óptica (TCO). Foram realizadas nos seguintes momentos: parte I, no diagnóstico e meses 1, 2, 4, 6, 9 e 12; parte II, na inclusão e a cada três meses. Eletrorretinograma campo total (ERGct) e eletrorretinograma multifocal (ERGmf) foram realizados na parte I, no 1.o mês e a cada seis meses e, na parte II, na inclusão e com 12 meses. A leitura dos exames, na parte I, foi efetuada por duas leitoras, não mascaradas; na parte II, foi realizada por três leitores mascarados e treinados, sendo considerada a leitura concordante entre, pelo menos, dois examinadores. As angiografias e TCO foram realizadas no aparelho Spectralis® (HRA+OCT, Heidelberg Engineering). Tratamento adicional com corticoterapia em doses imunossupressoras ou intensificação da imunossupressão sistêmica foi indicado nos casos com recidivas clínicas, na presença de sinais de atividade à AGF ou duas pioras consecutivas >= 30% no ERGct. Os sinais de atividade detectados na AGF, AIV e TCO foram denominados sinais subclínicos. RESULTADOS: Na parte I, foram incluídos nove pacientes (7F/2M) com idade mediana de 33 anos e intervalo mediano entre início dos sintomas e tratamento de 13 dias. Na apresentação inicial, sinais clínicos característicos da doença (coroidite difusa com hiperemia do disco óptico, descolamento seroso de retina e uveíte anterior acompanhados de...

OBJECTIVES: To describe the course of Vogt-Koyanagi-Harada disease (VKHD) prospectively, integrating clinical, structural and functional parameters. METHODS: Patients with VKHD in the acute (part I) and non-acute (more than 12 months from diagnosis) phases (part II) were included. Patients in the acute phase received a standard treatment with methylprednisolone pulsetherapy followed by high-dose oral corticosteroids with slow tapering during 15 months. Evaluations included clinical exams, fluorescein (FA) and indocyanine green (ICGA) angiographies and optical coherence tomography (OCT). In part I, they were performed at inclusion, then after 1,2,4,6,9,and 12 months; in part II, they were performed at inclusion then every 3 months for up to 12 months. Functional evaluation using electroretinography (ERG) was performed at inclusion and every 6 months in part I and at inclusion and at 12 months in part II. Two non-blinded readers analyzed the imaging exams in part I. In part II, three trained and blinded-readers performed the imaging exams analysis. For study`s purpose, at least two concordant readings were considered. Imaging exams utilized the Spectralis® (HRA+OCT, Heidelberg engineering). Inflammatory signs detected on FA, ICGA and OCT were denominated as subclinical signs. Additional treatment with high doses of corticosteroids or more intensive systemic immunosuppression was indicated in cases with clinical signs of inflammation, with subclinical signs on FA or with two consecutive worsening > 30% on ERG. RESULTS: Nine patients (7F/2M) were included in part I; median age was 33 years old and median time elapsed from onset of symptoms to treatment was 13 days. At disease presentation, classic signs (choroiditis, anterior uveitis, serous retinal detachment, optic disc hyperemia and extraocular manifestations) were observed; they improved in 30 days after treatment. Subclinical signs improved in variable periods of time: subfoveal choroidal thickness (CT)...

Echographic findings in the late stages of Vogt-Koyanagi-Harada disease in mexican population / Resultados ecográficos nas fases atrasadas da doença de Vogt-Koyanagi-Harada na população mexicana

Purpose: To correlate clinical findings of Vogt-Koyanagi-Harada disease with standardized echography findings in a cross-sectional, descriptive and observational study. Methods: Patients with Vogt-Koyanagi-Harada disease in the convalescent and recurrence phases were evaluated with standardized ocular echography. Eyes with opaque media were excluded. Clinical findings were correlated with echographic data. Results: Thirty-seven eyes of 25 patients were included. Best corrected visual acuity was in average 20/100 (0.70 logMAR). Clinical findings included: sunset glow fundus (92%), pigment migration (92%), nummular chorioretinal depigmented scars (68%) and subretinal fibrosis (64.8%). Standardized echography was able to recognize all the cases with subretinal fibrosis (n=24) described clinically. Standardized echography showed a 100% sensitivity and specificity of finding subretinal fibrosis. Subretinal fibrosis in patients with Vogt-Koyanagi-Harada represents a risk factor for low vision. In our patients’ eyes, presence of subretinal fibrosis had a 2.5 time relative risk of having a visual acuity equal or worst to 20/70. Conclusions: Standardized echography represents a useful tool in patients with VKH in the chronic (convalescence and recurrence) phase of the disease. Subretinal fibrosis, a sight threatening complication in the convalescence and recurrent phases of Vogt-Koyanagi-Harada, can be diagnosed with ocular echography, with characteristic images. Knowledge of these images can be useful in cases with opaque media and bilateral anterior segment granulomatous inflammatory disease. .

Objetivo: Correlacionar achados clínicos da síndrome de Vogt-Koyanagi-Harada com resultados ecográficos padronizado da doença em um estudo transversal, descritivo e observacional. Métodos: Pacientes com a doença de Vogt-Koyanagi-Harada, o convalescente e recorrência em fases padronizadas foram avaliados com ecografia ocular. Olhos com material opaco foram excluídos. Achados clínicos foram correlacionados com dados ecográficos. Resultados: Um total de 25 pacientes e trinta e sete olhos foram incluídos no estudo. A acuidade visual (AV) 20/100 foi em média 0.70 logMAR. Os achados clínicos incluídos: sunset glow fundus (92%), pigmento migração (92%), numular despigmentado cicatrizes coriorretinianas (68%) e fibrose sub-retiniana (64,8%). A ecografia padronizada foi capaz de reconhecer todos os casos de fibrose sub-retiniana (n= 24) descrito clinicamente. A ecografia revelou um padrão 100% de sensibilidade e especificidade do diagnóstico fibrose sub-retiniana. Sub-retiniana em pacientes com fibrose Vogt-Koyanagi-Harada representa um fator de risco para a baixa visão. Em nossos pacientes olhos, presença de fibrose subretiniana tinham um risco relativo 2,5 hora de ter uma acuidade visual igual ou pior para 20/70. Conclusão: Ecografia padronizadarepresenta uma ferramenta útil em pacientes portadores da doença na fase crônica (convalescença, e recidiva). Fibrose sub-retiniana, uma visão ameaçadora e complicação na convalescença e recorrentes nas fases da Síndrome de Vogt-Koyanagi- Harada, podem ser diagnosticados com ecografia ocular, com imagens características. O conhecimento dessas imagens pode ser útil em casos com material opaco e segmento anterior bilateral da doença inflamatória granulomatosa. .

Vogt-Koyangi-Harada en fase crónica y terapia biológica: reporte de cuatro casos / Vogt-Koyanagi-Harada in chronic phase of recurrence and biological therapy: report of four cases

Objetivo: describir cuatro casos de Vogt Koyanagi Harada (VKH), con uveítis en fase crónica de recurrencia y la respuesta a fármacos anti TNF alfa. Diseño: reporte de casos. Métodos: se realizó estudio descriptivo tipo reporte de caso, mediante recolección y análisis de historias clínicas de pacientes adultos de un centro de referencia de enfermedades autoinmunes, que cumplieran criterios diagnósticos de VKH y que estuvieran en tratamiento con terapia biológica para dicha patología. Resultados: en el presente artículo informamos una serie de cuatro casos de VKH, de los cuales todas fueron mujeres entre los 19 y 57 años, en fase crónica y de recurrencia de la enfermedad. En todos los casos existió refractariedad al uso de esteroides a dosis altas y no respuesta a inmunosupresores como ciclosporina y metotrexate, requiriéndose instauración de terapia biológica anti TNF alfa con control de su patología. Conclusiones: En el VKH en fases tardías la respuesta a altas dosis de esteroides y a inmunosupresores convencionales puede ser fallida, ante lo cual el uso de terapia biológica con fármacos anti TNF alfa y anti CD20 es una alternativa factible, requiriéndose aún mayores estudios en este campo que permitan una prescripción eficaz y segura.

Objective: to describe four cases of Vogt Koyanagi Harada (VKH) disease, in chronic and recurrence phase that were treated with anti-TNF biological therapy and their response to this therapy. Design: cases reports. Methods: We performed a descriptive, case report with clinical chart review of adult patients in a center of autoimmune diseases who met diagnostic criteria for VKH and treated with biological therapy. Results: We report four cases of VKH treated in our center of autoimmune diseases, which were all women between 19 and 57 years, in chronic and recurrence phase of disease. In all cases there was refractory to steroid use at high doses and no response to immunosuppressive treatment as cyclosporine and methotrexate, requiring introduction of anti-TNF biological therapy to control their disease. Conclusions: In chronic phases of VKH the response to high doses of steroids and conventional immunosuppressive therapy may be failed, therefore the use of biological therapy with anti-CD20 and anti-TNF alpha is a viable alternative, still requiring further study in this fi eld to enable an eff ective and safe prescription.

Úvea y enfermedades sistémicas / Uvea and systemic diseases

El ojo, además de entregarnos el sentido de la visión, también nos permite conocer la salud general del organismo. Muchas enfermedades sistémicas se manifiestan en el órgano visual antes, durante o después del debut de ellas a nivel sistémico. Este compromiso visual es variado y depende de la enfermedad en cuestión, destacando la escleritis, uveítis y vasculitis retinales. Conocer el estado ocular permitirá al clínico realizar diagnósticos más asertivos y oportunos, realizar el tratamiento más adecuado y definir pronóstico en varias enfermedades, que tienen al globo ocular como un órgano blanco. El objetivo de esta revisión es atraer la atención del lector sobre el compromiso oftalmológico en varias enfermedades

The eye besides giving us sight, it let us know the general health of the whole body as well. Many systemic diseases become evident in the visual organ before, during or after its systemic onset. The visual involvement in these diseases is wide and depends on the underlying disease. It is worth to stand out the escleritis, uveitis and retinal vasculitis. The knowledge of the ocular health will let the physician to diagnose more accurately and in time, to start the most appropriate treatment and to define the prognosis of several diseases that have the eye as a target organ. The aim of this review is to draw the reader's attention to the ophthalmic involvement in several systemic diseases

Síndrome de Vogt-Koyanagi-Harada (SVKH): reporte de un caso / Vogt-Koyanagi-Harada (SVKH): case report

Introducción: Describimos un caso del síndrome de Vogt-Koyanagi-Harada (SVKH) de etiología desconocida. Caso Clínico: Mujer de 18 años de edad con antecedente de eritema conjuntival y disminución de la agudeza visual por seis meses, tratada con corticoides por presentar cefalea, trastorno de conciencia, crisis convulsiva y fiebre. Es admitida y se observa facies de luna llena, inyección conjuntival marcada, jiba cervical, poliosis incipiente, discreta alopecia. Reflejo corneal disminuido bilateralmente, signos meníngeos presentes, Babinski bilateral, uveítis exudativa anterior bilateral. Exámenes Auxiliares: leucocitosis con desviación izquierda, hiperglicemia, inmunoglobulinas séricas Ig G e Ig M positivas para Herpes 1y Toxoplasma, LCR: 27 células 100% mononucleares, 108 mg/dl de glucosa, 54mg/dl de proteínas. Discusión: El caso descrito presentó: fase prodrómica o meníngea, uveítica, de convalecencia y crónica - recurrente en el transcurso de la enfermedad. La evolución clínica fue favorable, pero la recurrencia luego del alta con disminución de la agudeza visual y uveítis bilateral orientó al diagnóstico de SVKH. Durante el seguimiento, la inflamación intraocular se mantuvo en forma crónica con pérdida considerable de la agudeza visual que no coincide con el pronóstico visual en el SVKH descrito en la literatura. Presentamos este caso por la inusual presentación y riqueza de síntomas.

Introduction: We describe a case of Vogt-Koyanagi-Harada syndrome (SVKH) of unknown etiology. Clinic case: 18 year-old female with a history of conjunctival erythema and decreased visual acuity from 6 months, treated with corticoids. She was admitted with headache, disturbance of consciousness and fever. At physical examination: full moon face, marked conjunctival injection, cervical jiba, incipient poliosis, and discrete alopecia. Decreased corneal reflex bilaterally. Meningeal signs, bilateral Babinski, anterior bilateral exudative uveitis. Laboratory tests: leukocytosis with left shift, hyperglycemia, serum immunoglobulins Ig G and Ig M positive for Herpes I and Toxoplasma, LCR: 27% mononuclear cells 100, 108 mg / dl glucose, 54mg/dl protein. Discussion: We describe a case that presented: meningeal or prodromal phase, uveítica, convalescent and chronic - recurrent in the course of their disease. The clinical outcome was favorable, but the recurrence after withdrawal of corticosteroids with decreased visual acuity and bilateral uveitis target in the diagnosis of SVKH. During follow-up intraocular inflammation remained in a chronic loss of visual acuity that does not match the visual prognosis in SVKH described in the literature. We present this case for the unusual presentation of symptoms wealth.
