RÉSUMÉ

The NLRP3 inflammasome is a cellular multimeric protein complex that plays a crucial role in inflammation and immune responses. It consists of three main components: Nod-like receptor protein 3(NLRP3), apoptosis-associated speck-like protein containing(ASC)and cysteine protease 1(caspase-1). Uveitis is a broad term encompassing a range of inflammatory diseases that primarily affect the iris, ciliary body, vitreous, retina and choroid. It is considered a major cause of blindness globally. Numerous studies have demonstrated the involvement of NLRP3 inflammasome in the onset and progression of uveitis, indicating its potential as a significant therapeutic target for uveitis in the future. This article provides an overview of the structure, biological functions and activation pathways of the NLRP3 inflammasome, as well as the current research progress on its association with different types of uveitis. Additionally, it discusses the application potential of the NLRP3 inflammasome in the treatment of uveitis.

RÉSUMÉ

Vogt–Koyanagi–Harada (VKH) disease, a bilateral granulomatous panuveitis associated with multisystem involvement, is a T-cell-mediated autoimmune disorder in which cytotoxic T-cell target melanocytes in genetically susceptible individuals. Recently, there has been an increase in literature on the new onset of uveitis and reactivation of previously diagnosed cases of uveitis following Covid-19 vaccinations. It has been postulated that Covid-19 vaccines can lead to an immunomodulatory change resulting in an autoimmune phenomenon in the recipients. VKH following COVID-19 infection was reported in four patients and a total of 46 patients developing VKH or VKH-like disease following COVID-19 vaccinations. There are reports of four patients who had been recovering or recovered from VKH after receiving the first dosage of the vaccine and developed worsening of ocular inflammation after receiving the second dose of the vaccine.

RÉSUMÉ

Purpose: To report the outcome of surgical intervention for inflammatory, exudative retinal detachment (ERD). Methods: A retrospective analysis of eyes with ERD that underwent vitrectomy. Results: Twelve eyes (10 patients) with ERD, non?responsive to medical therapy, underwent vitrectomy. The mean age was 35.7 ± 17.7 years. Five eyes (42%) had Vogt–Koyanagi–Harada disease, three (25%) had presumed tuberculosis (TB), two (17%) pars planitis, and one (8%) had sympathetic ophthalmia. The mean time of vitrectomy was 6.76 ± 4.1 months after onset. Six (50%) eyes had a recurrence, two settled with medical treatment, and four underwent re?surgery. The mean follow?up was 2.7 years. At the last visit, 10 (83.3%) eyes had attached retina; the best?corrected visual acuity (BCVA) had reduced to 1.6 ± 0.7 logarithms of the minimum angle of resolution (logMAR) from 1.3 ± 0.7 at baseline. Conclusion: Vitrectomy in ERD can act as an adjuvant to conventional medical therapy and help maintain structural integrity. Early vitrectomy may help preserve visual function.

RÉSUMÉ

El síndrome de Vogt-Koyanagi-Harada es una enfermedad autoinmune multisistémica crónica, caracterizada por panuveítis difusa granulomatosa bilateral con desprendimiento exudativo de retina y papilitis. Compromete el sistema nervioso central (meninges, disacusia neurosensorial) así como piel y mucosas. A pesar de ser una enfermedad compleja y poco frecuente, se hace necesario comprender la importancia del diagnóstico rápido y el tratamiento oportuno con seguimiento especializado. Es por ello que se decidió realizar una revisión de la literatura con el objetivo de actualizar los conocimientos existentes sobre este tema. La búsqueda se realizó en diferentes publicaciones y textos básicos de la especialidad. Las fuentes consultadas fueron las bases de datos PubMed y Google Scholar. El diagnóstico de la enfermedad es esencialmente clínico y son los oftalmólogos quienes más lo sospechan por ser los síntomas oculares los más frecuentes y dramáticos. El pronóstico visual de los pacientes es generalmente bueno si el diagnóstico es precoz y se indica un tratamiento adecuado. Los corticosteroides sistémicos a altas dosis asociados a inmunosupresores y agentes biológicos tienen gran impacto en la evolución de la enfermedad, sobre todo estos últimos a nivel mundial, previniendo complicaciones y permitiendo resultados visuales satisfactorios para una mejor calidad de vida del paciente(AU)


Vogt-Koyanagi-Harada syndrome is a chronic multisystem autoimmune disease characterized by bilateral diffuse granulomatous panuveitis with exudative retinal detachment and papillitis. It involves the central nervous system (meninges, sensorineural dysacusis) as well as skin and mucous membranes. In spite of being a complex and infrequent disease, it is necessary to understand the importance of rapid diagnosis and timely treatment with specialized follow-up. For this reason, it was decided to carry out a review of the literature with the aim of updating the existing knowledge on this subject. The search was carried out in different publications and basic texts of the specialty. The sources consulted were the PubMed and Google Scholar databases. The diagnosis of the disease is essentially clinical and it is the ophthalmologists who suspect it the most because the ocular symptoms are the most frequent and dramatic. The visual prognosis of patients is generally good if the diagnosis is early and adequate treatment is indicated. Systemic corticosteroids at high doses associated with immunosuppressants and biological agents have a great impact on the evolution of the disease, especially the latter worldwide, preventing complications and allowing satisfactory visual results for a better quality of life of the patient(AU)

RÉSUMÉ

Covishield is in wide use in India with about 80% efficacy. Serious side effects are still under study. A 30-year-old female presented to us 7 days post-vaccination with a 5-day history of sudden diminution of vision in both eyes. The clinical findings were suggestive of the Vogt-Koyanagi-Harada (VKH) syndrome. She was treated with high-dose oral steroids. At this juncture, the association was unclear. However, it was justified by an acute flare-up of uveitis on day 2 post the second dose of vaccination despite ongoing steroids. A direct correlation of Harada-like syndrome with the Covishield vaccine is observed here

RÉSUMÉ

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.

RÉSUMÉ

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.

RÉSUMÉ

@#AIM:To investigate the changes of Notch receptors and interleukin(IL)-22 expression in patients with Vogt-Koyanagi-Harada(VKH)syndrome, and to assess the regulatory activity of Notch signaling to IL-22 production by CD4+ T cells in patients with VKH syndrome.<p>METHODS: Thirty-five patients with VKH syndrome(including fifteen active VKH and twenty inactive VKH)and twelve healthy controls were enrolled. Plasma was isolated, and CD4+T cells were purified. Notch receptors were investigated by qRT-PCR and Western blot. Plasma IL-22 expression was measured by ELISA. The percentage of Th17 and Th22 cells was investigated by flow cytometry. CD4+T cells, which were purified from active VKH patients, were stimulated with Notch signaling inhibitor DAPT. mRNA expression of transcription factor in CD4+T cells as well as IL-22 secretion by CD4+T cells was investigated.<p>RESULTS: Notch1-Notch3 in CD4+T cells from active VKH syndrome patients was significantly elevated in comparison with inactive VKH and healthy controls. Plasma IL-22 expression and percentage of Th17 and Th22 was notably increased in active VKH syndrome in comparison with inactive VKH and controls. DAPT stimulation inhibited Notch signaling pathway in CD4+T cells, leading to the down-regulation of AhR mRNA and IL-22 secretion.<p>CONCLUSION:Notch-AhR-IL-22 signaling pathway might take part in the pathogenesis of VKH syndrome.

Objective@#To have a profound understanding of anti-N-methyl-D-aspartic receptor (anti-NMDAR) encephalitis, through the clinical analysis of 5 cases of anti-NMDAR encephalitis, and literature review.@*Methods@#This is a retrospective analysis. Five cases of anti-NMDA receptor encephalitis treated from May 2010 to June 2015, in the Department of Neurology, Beijing Friendship Hospital affiliated to Capital Medical University, were included in this study. The clinical data, including clinical manifestation, past history, radiological features, serum and cerebral spinal fluid examinations, treatment and prognosis, were analyzed.@*Results@#Among the 5 cases, 3 young female and 2 middle-to old-aged male. The clinical features of the onset was mental and behavior disorder, as well as seizure and extrapyramidal features, like facial and limbic involuntary movements or tremor. Coma and hypopnea was severe in 3 young female cases, needing assistance of mechanical ventilator, while the manifestation of 2 male patients was much mild, need not assisted respiration. 1 case had teratoma of ovary, 1 case had Vogt-Koyanagi-Harada syndrome. The anti-NMDA receptor antibody was positive in cerebraospinal fluid of all 5 cases, but in serum of 3 cases, serum and CSF Epstein-Barr virus (EBV) IgM antibody was positive in 1 case, while herpes simplex I virus (HSV-1) IgM antibody positive in another case, and anti-myelin oligodendrocyte glycoprotein (MOG) antibody was seen in serum and CSF in 1 case. The time interval from the onset to treatment was 10-37 d (18.8±9.8 d). IVIG was used in all of the 5 cases, glucocoticoid in 4 cases, and plasma exchange in 3 cases. One case with Vogt-Koyanagi-Harada syndrome, having a long time before diagnosis and treatment, died, while the other 4 cases had good prognosis, and had no relapse.@*Conclusions@#Mental and behavior disturbance is common at onset of anti-NMDAR encephalitis. The radiological and lab examination may be normal. It may be accompanied with HSV-1 or EBV infection, anti-MOG antibody may be positive in this disease. Active treatment is important.

RÉSUMÉ

PURPOSE: To report a case of atypical Vogt–Koyanagi–Harada disease that occurred after an acute angle closure glaucoma attack. CASE SUMMARY: A 48-year-old female presented with bilateral visual disturbance accompanied by headache and ocular pain. The patient had no specific past medical or family history except taking oral contraceptives for 10 years. Despite the normalization of intraocular pressure in a local clinic, a shallow-depth anterior chamber and forward displacement of the iris–lens diaphragm remained unresolved. The depth of the anterior chamber had increased in both eyes after laser therapy but without recovery of her visual acuity. B-scans showed ciliochoroidal effusion. Anterior chamber inflammation was observed in both eyes. Optical coherence tomography showed lobulated and serous retinal detachment involving the macula of both eyes. However, fluorescence angiography findings showed no multiple hyperfluorescence, which is unusual for typical cases of Vogt–Koyanagi–Harada disease. The patient was diagnosed with atypical Vogt–Koyanagi–Harada disease and was treated with eyedrops and intravenous steroid pulse therapy, after which she was converted to oral medications with immunosuppressants. After 1 month, no serous retinal detachment was detected. After 3 months, best corrected visual acuity (logMAR) was 0.0 in both eyes, and there has been no recurrence on follow-up. CONCLUSIONS: Atypical Vogt–Koyanagi–Harada disease at presentation can mimic acute attacks of angle closure glaucoma. Therefore, if there is no improvement after treatment for angle closure glaucoma including laser iridotomy, other diseases including Vogt–Koyanagi–Harada disease must be considered and the patient should be closely monitored.

RÉSUMÉ

PURPOSE: To report a case of Vogt-Koyanagi-Harada (VKH) disease with chronic recurrence, which was treated with intravitreal dexamethasone implantation. CASE SUMMARY: A 39-year-old female presented with decreased visual acuities in both eyes accompanied by headaches and tinnitus the previous week. On fundus examination and optical coherence tomography, multiple serous retinal detachments with subretinal septa were observed in both eyes, and she was diagnosed with VKH disease. After undergoing high dose intravenous steroid therapy at another hospital, she was treated with oral prednisolone and immunosuppressant drugs. However, she showed frequent recurrences, and also complained of side effects from prolonged systemic steroids. We then performed intravitreal injections of dexamethasone implants in both eyes at 3-week intervals. One month following the injections, the inflammations in the anterior chamber and vitreous opacities were improved. Until the last visit at 6 months after the injection, there was no significant recurrence of inflammation, although oral prednisolone had been tapered. CONCLUSIONS: In VKH disease, intravitreal dexamethasone implantation may be an effective treatment option if chronic recurrence occurs, despite systemic steroid and immunosuppressant therapy or sustained treatment being difficult to maintain because of side effects.

RÉSUMÉ

El síndrome de Vogt Koyanagi Harada (VKH) consiste en una panuveitis bilateral que forma parte de los síndromes uveomeníngeos.El tratamiento en estadio crónico es difícil por presentar pobre respuesta a la inmunomodulación, por lo que se recurre a opcionesterapéuticas como agentes biológicos tipo anti-TNF alfa. Se describe el caso de una paciente con VKH severo y resistencia al infliximab,quien mostró respuesta al adalimumab. El adalimumab es un anticuerpo monoclonal humanizado efectivo en casos de resistenciaal infliximab en pacientes con síndrome de VKH crónico persistente. El caso es de interés por ser infrecuente la resistencia a estemedicamento en la práctica clínica, y el uso del activador de plasminógeno tisular contribuyó significativamente en la mejoría visual.


Vogt Koyanagi Harada syndrome (VKH) is a bilateral panuveitis included in the uveomeningeal syndromes. Treatment of its chronicstage is difficult because of poor response to immunomodulation. Other therapeutic options include biological agents such as antiTNFalpha. We present the case of a patient with severe VKH resistant to infliximab that responded to adalimumab. Adalimumab isa humanized monoclonal antibody effective when there is resistance to infliximab in patients with chronic persistent VKH syndrome.The case presented is interesting because of uncommon resistance to this drug in the clinical practice; the use of tissue plasminogenactivator contributed significantly to visual improvement.
