RESUMO

OBJECTIVE: The aim of this study was to analyze HLA alleles in patients with Behçet disease (BD) and their correlation with ophthalmic manifestations (OMs) in a multiethnic Brazilian population. METHODS: This case-control study compared 72 BD patients with or without OM who underwent a thorough ophthalmologic evaluation, including best-corrected visual acuity, bino-ophthalmoscopy, and HLA analysis, with 144 matched healthy controls. Fluorescein angiography was also performed in the patients with BD and OM. HLA class I (A, B, and C) and II (DRB1, DQB1, and DQA1) typing were performed using PCR-SSO. RESULTS: Of 72 patients with BD, 42 (58%) had OM. The HLA-B*51 and -A*26 alleles were more frequent in patients with BD than in controls (23.6% vs 14.6% and 12.5% vs 4.3%, respectively), but could not differentiate OM risk. The HLA alleles of BD patients that differentiated those with and without OM were HLA-B*15 (40.5% vs 20.7%; odds ratio [OR], 2.59; p = 0.0059), HLA-C*02 (33.3% vs 13.4%; OR, 3.20; p = 0.0024), and HLA-DQB1*03 (64.3% vs 45.7%, p = 0.017), whereas HLA-A*03 (0.0% vs 13.3%, p = 0.006) and HLA-DRB1*15 (4.8% vs 19.5%; OR, 0.21; p = 0.0121) were protective against OM. CONCLUSIONS: In this study of a Brazilian multiethnic BD population, alleles were similar between groups of BD patients with and without OM. We described HLA-B*15, -C*02, and -DQB1*03 as risk factors and -A*03 and -DRB1*15 as protective factors for OM in BD, which could function as biomarkers for predicting disease phenotypes.

RESUMO

T cells are present in early stages of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and play a major role in disease outcome and long-lasting immunity. Nasal administration of a fully human anti-CD3 monoclonal antibody (Foralumab) reduced lung inflammation as well as serum IL-6 and C-reactive protein in moderate cases of COVID-19. Using serum proteomics and RNA-sequencing, we investigated the immune changes in patients treated with nasal Foralumab. In a randomized trial, mild to moderate COVID-19 outpatients received nasal Foralumab (100 µg/d) given for 10 consecutive days and were compared to patients that did not receive Foralumab. We found that naïve-like T cells were increased in Foralumab-treated subjects and NGK7+ effector T cells were reduced. CCL5, IL32, CST7, GZMH, GZMB, GZMA, PRF1, and CCL4 gene expression were downregulated in T cells and CASP1 was downregulated in T cells, monocytes, and B cells in subjects treated with Foralumab. In addition to the downregulation of effector features, an increase in TGFB1 gene expression in cell types with known effector function was observed in Foralumab-treated subjects. We also found increased expression of GTP-binding gene GIMAP7 in subjects treated with Foralumab. Rho/ROCK1, a downstream pathway of GTPases signaling was downregulated in Foralumab-treated individuals. TGFB1, GIMAP7, and NKG7 transcriptomic changes observed in Foralumab-treated COVID-19 subjects were also observed in healthy volunteers, MS subjects, and mice treated with nasal anti-CD3. Our findings demonstrate that nasal Foralumab modulates the inflammatory response in COVID-19 and provides a novel avenue to treat the disease.

RESUMO

We report a case of Susac syndrome after SARS-CoV-2 infection and subsequent vaccination that presented with meningitis and retinal microembolisation in the form of paracentral acute middle maculopathy (PAMM). After presenting with headache, fever and myalgia followed by scotomata, a woman in her 50s was hospitalised for meningitis; she had had mild COVID-19 infection 2 months prior to admission, having received the first vaccine dose 1 month prior to the neurological manifestation. Eye fundus examination and optical coherence tomography were suggestive of PAMM. D-dimer levels and erythrocyte sedimentation rate were elevated. Before infectious investigation results were available, she was started on empirical antibiotic and antiviral treatment. Having ruled out infectious causes, she was started on high-dose prednisolone. After 1 month, there was partial resolution of retinal lesions. This case highlights that exposure to SARS-CoV-2 antigen may be related to this rare syndrome; treatment with steroids may improve central and retinal impairment.

RESUMO

BACKGROUND: Immune hyperactivity is an important contributing factor to the morbidity and mortality of COVID-19 infection. Nasal administration of anti-CD3 monoclonal antibody downregulates hyperactive immune responses in animal models of autoimmunity through its immunomodulatory properties. We performed a randomized pilot study of fully-human nasal anti-CD3 (Foralumab) in patients with mild to moderate COVID-19 to determine if its immunomodulatory properties had ameliorating effects on disease. METHODS: Thirty-nine outpatients with mild to moderate COVID-19 were recruited at Santa Casa de Misericordia de Santos in Sao Paulo State, Brazil. Patients were randomized to three cohorts: 1) Control, no Foralumab (n=16); 2) Nasal Foralumab (100ug/day) given for 10 consecutive days with 6 mg dexamethasone given on days 1-3 (n=11); and 3) Nasal Foralumab alone (100ug/day) given for 10 consecutive days (n=12). Patients continued standard of care medication. RESULTS: We observed reduction of serum IL-6 and C-reactive protein in Foralumab alone vs. untreated or Foralumab/Dexa treated patients. More rapid clearance of lung infiltrates as measured by chest CT was observed in Foralumab and Foralumab/Dexa treated subjects vs. those that did not receive Foralumab. Foralumab treatment was well-tolerated with no severe adverse events. CONCLUSIONS: This pilot study suggests that nasal Foralumab is well tolerated and may be of benefit in treatment of immune hyperactivity and lung involvement in COVID-19 disease and that further studies are warranted.

RESUMO

OBJECTIVE: Takayasu arteritis (TA) is a chronic, granulomatous, idiopathic, inflammatory disease that primarily affects large vessels. The objective of this study was to evaluate and describe the ocular manifestations of TA, correlating the resistivity and pressure in retrobulbar vessels by colour Doppler and retinal angiography. DESIGN: Cross-sectional study. PARTICIPANTS: Twenty-one patients with TA, 42 eyes, and 21 patients without TA (42 eyes) as control subjects. METHODS: This study was performed in clinical practice. Patients with TA received complete ophthalmologic examination, fluorescein and indocyanine green angiography, and colour Doppler ultrasound to evaluate blood flow in the retrobulbar vessels. RESULTS: A statistical correlation was found between peak systolic velocity (PSV) in the ophthalmic artery (OA) and Heidelberg retinal angiography (HRA) examination results (p = 0.006), and resistivity index (RI) in the OA was abnormal in patients with long (average, 14 years) versus short (average, 5.5 years) onset time of the disease (p = 0.035). RI in the central retinal artery (CRA) was abnormal in patients with a long time of disease onset (mean 14.4 years) versus those with a short time (mean 4.6 years) of onset (p = 0.006). CONCLUSIONS: The longer the onset of the disease, the more commonly the RI showed changes in the OA and CRA, and, to a lesser extent, in the short posterior ciliary artery. When abnormalities are observed in the HRA examination, abnormal PSV in the OA may be present. Doppler blood flow evaluation and HRA may have predictive value in all patients with TA as part of serial monitoring.

RESUMO

Estabelecer padrão evolutivo de um caso de esclerite nodular à ultrassonografia de alta frequência durante o tratamento. Mulher, 27 anos, com manifestação inicial de uveíte intermediária, edema macular bilateral após tratamento clínico com corticosteroide tópico e via oral. Após quatro meses, observou-se a formação de um nódulo escleral no olho direito quando foi submetido à ultrassonografia de alta frequência (Paradigm, transdutor de 50 MHz, técnica de imersão). A lesão do olho direito foi caracterizada à ultrassonografia de alta frequência como uma lesão nodular da parede anterior temporal inferior associada à redução localizada da espessura da escleral. Após a injeção intravítrea de triancinolona para tratamento do edema macular, observou-se a regressão clínica do nódulo escleral no olho direito, mantendo reduzida a espessura escleral. A ultrassonografia de alta frequência auxiliou no diagnóstico da esclerite nodular durante as fases de tratamento e na identificação da sua sequela característica, o afinamento escleral.


To stablish evolutionary pattern of a case of nodular scleritis with high frequency ultrasound during treatment. Twenty-seven year old female, initial manifestation of intermediate uveitis, bilateral macular edema after clinical treatment with topical and oral steroids. After four months, we observed the formation of a scleral nodule in the right eye when patient underwent high frequency ultrasound (Paradigm, 50 MHz transducer, immersion technique). The lesion in right eye was characterized at high frequency ultrasound as a nodular lesion located at the anterior inferior temporal wall associated with localized reduction of scleral thickness. After intravitreal injection of triamcinolone for treatment of macular edema, clinical regression of the scleral nodule was observed in right eye, maintaining reduced scleral thickness. High frequency ultrasound assisted in the diagnosis of nodular scleritis during the phases of treatment and in the identify its characteristic sequel feature, the scleral thinning.

RESUMO

A case of a 14 year-old boy that was admitted complaining of bilateral ocular visual blurring for 2 years is reported. The ophthalmological examination disclosed bilateral mild optic disc hyperemia and swelling, retinal exudation, few retinal hemorrhages, multiple aneurysms, as well as vasculitis. Fluorescein angiography showed extensive peripheral retinal ischemia, dilatations and hyperfluorescence of the vessels walls, and leakage of the optic disc in the late phases in both eyes. This rare case represents an entity characterized by peripheral retinal vascular occlusion, retinal vasculitis, multiple posterior retinal aneurysms, and neuroretinitis (IRVAN). Systemic evaluation and laboratory work-up did not suggest any systemic abnormality. Panretinal laser photocoagulation was performed in both eyes, and the patient was treated with oral prednisone with maintenance of the visual acuity after 1 year of follow-up. Laser treatment should be considered when angiographic evidence of widespread retinal no perfusion is present, and before the development of signs of retinal neovascularization.

RESUMO

Relatamos caso de um paciente de 14 anos, sexo masculino, que foi admitido com queixa de embaçamento visual bilateral há dois anos. Ao exame oftalmológico observou-se leve hiperemia e edema de disco óptico bilateral, exsudação retiniana, poucas hemorragias retinianas, múltiplos aneurismas, assim como sinais de vasculite. A angiofluoresceinografia demonstrou isquemia periférica extensa, dilatações e hiperfluorescência das paredes dos vasos, e vazamento tardio do disco óptico nas fases finais do exame em ambos os olhos. Este caso representa uma rara entidade caracterizada por oclusão retiniana vascular periférica, vasculite retiniana, múltiplos aneurismas retinianos e neurorretinite (IRVAN). Avaliação sistêmica e laboratorial não revelaram nenhuma anormalidade. O paciente foi submetido à panfotocoagulação de retina com laser de argônio em ambos os olhos, e iniciado tratamento com prednisona via oral, com manutenção da acuidade visual de 20/25 depois de um ano de acompanhamento. O tratamento com laser deve ser considerado quando houver qualquer evidência angiográfica de má perfusão retiniana, e antes do desenvolvimento de qualquer sinal de neovascularização de retina.

RESUMO

OBJETIVO: Avaliar retrospectivamente as alterações oftalmológicas de crianças e adolescentes com lúpus eritematoso sistêmico juvenil (LESJ) em um serviço de reumatologia pediátrica terciário. MÉTODOS: Avaliamos 117 pacientes com LESJ (85,5% do gênero feminino, 60,7% não caucasoides) com média de idade de 10,4 anos e média de tempo de evolução da doença de 5,4 anos que preenchiam no mínimo quatro critérios de classificação do LES de acordo com o American College of Rheumatology de 1997. Aplicamos um protocolo que continha dados clínicos e demográficos, queixas e alterações oftalmológicas, idade do início, tempo de uso e dose cumulativa das medicações. RESULTADOS: Dos 117 pacientes, 24 (20,5%) apresentaram alterações oftalmológicas. Destes, 16 apresentaram alteração de fundo de olho associada a hipertensão arterial sistêmica e/ou uso de cloroquina, quatro apresentaram catarata, dois apresentaram glaucoma e dois apresentaram catarata e glaucoma. A média de idade do aparecimento das alterações oftalmológicas foi de 14,1 anos. Os pacientes com alterações oftalmológicas receberam, estatisticamente, maiores doses e tempos de pulsoterapia de glicocorticoide em relação aos pacientes sem alterações oftalmológicas [1,5 (0,4-1,6) versus 1 (0,2-1,6) mg/kg, P = 0,003; 25,7 (2-99) versus 17,8 (1-114) meses, P = 0,0001; respectivamente]. CONCLUSÃO: Verificamos alta prevalência de alterações oftalmológicas relacionadas principalmente ao tratamento do LESJ, o que demonstra a necessidade de avaliações regulares mesmo em pacientes assintomáticos, visando ao diagnóstico e intervenção precoces e à diminuição da morbidade ocular relacionada a essa doença.


OBJECTIVE: To assess retrospectively the ocular changes in children and adolescents with juvenile systemic lupus erythematosus (JSLE) in a tertiary pediatric rheumatology service. METHODS: This study assessed 117 JSLE patients (85.5% female, 60.7% non-Caucasian), who met at least four criteria of the 1997 SLE classification of the American College of Rheumatology. Their mean age was 10.4 years, and their mean time of disease progression was 5.4 years. A protocol containing clinical and demographic data, ophthalmologic complaints and changes, age of onset, duration of medication use, and cumulative medication dose was applied. RESULTS: Of the 117 patients, 24 (20.5%) had ocular changes. Sixteen of them had abnormal fundoscopy associated with systemic hypertension and/or use of chloroquine; four had cataract; two had glaucoma; and two had cataract and glaucoma. The mean age of ocular change onset was 14.1 years. Patients with ocular changes received statistically higher and longer doses of glucocorticoid pulse therapy as compared with patients without ocular changes [1.5 (0.4 to 1.6) versus 1 (0.2 to 1.6) mg/kg, P = 0.003; 25.7 (2-99) versus 17.8 (1-114) months, P = 0.0001, respectively]. CONCLUSION: A high prevalence of ocular changes relating mainly to the treatment of JSLE was observed. This demonstrates the need for regular ophthalmologic examinations even in asymptomatic patients, aiming at the early diagnosis and intervention, and at decreasing the ocular morbidity related to that disease.

RESUMO

PURPOSE: To report fundus autofluorescence (FA) and spectral domain optical coherence tomography (SDOCT) findings in serpiginous choroiditis. DESIGN: Case report. METHODS: SDOCT and FA imaging of a 37-year-old woman with bilateral recurrent serpiginous choroiditis. RESULTS: Active new lesions disclosed hyperautofluorescence, in contrast to hypoautofluorescent scarred lesions. SDOCT showed increased reflectance of the choroid and deeper retinal layers, along with disruption of the photoreceptor inner and outer segment junction in both active and inactive lesions. CONCLUSION: Autofluorescence imaging and SDOCT are useful noninvasive methods for the evaluation of serpiginous choroiditis. Autofluorescence imaging allows identification of recurrences and retinal pigment epithelium involvement in the follow-up of this disease.

RESUMO

PURPOSE: To investigate the immunohistochemical expression (IGF-1, EGFr, EGF, c-erbB-2/HER-2/neu, PDGF-A, PDGF-B, FGF and VEGF) in patients with Graves' ophthalmopathy. METHODS: Twenty-four samples (Graves' ophthalmopathy patients) underwent lateral rectus muscle and surrounding fibrous and adipose tissue biopsy. The control group was obtained by strabismus surgery. Correlation between clinical-ophthalmologic, endocrinological, ultrasonographic findings, and immunohistochemical expression was performed. RESULTS: IGF-1: There were 7 positive cases (29.2%). There was a direct relation with higher CAS (clinical activity score) in all of them and if only CAS equal or higher than 5 was considered, this was 54.5%. FGF: There was expression in 5 cases (20.8%) with a direct relation in all those with higher CAS (>5) (45.4%). VEGF: There were two positive cases (8.3%) for VEGF in endothelial cells, in these cases the patients also presented CAS higher than 5. There was no expressions of all growth factors in the control group. CONCLUSIONS: All patients, except one, with positive expression of FGF, IGF-1 and VEGF showed CAS greater than 5, suggesting in this way an important role of these growth factors in the pathogenesis and severity of Graves' ophthalmopathy. However, statistical analysis revealed only significant association between IGF-1 and male sex (P=0.034). Low ultrasound reflectivity and endocrine status may not correlate directly with disease activity or with immunoexpression of growth factors and c-erbB-2/HER-2/neu.

OBJETIVO: Investigar a expressão imuno-histoquímica de IGF-1, EGFr, EGF, c-erbB-2/HER-2/neu, PDGF-A, PDGF-B, FGF e VEGF na oftalmopatia de Graves. MÉTODOS: Vinte e dois pacientes (oftalmopatia de Graves) foram submetidos à biópsia do músculo reto lateral e tecido fibroso e adiposo adjacente. O grupo controle foi de pacientes de cirurgia de estrabismo. Foi feita correlação entre achados clínico-oftalmológicos, endocrinológicos, ultra-sonográficos e da expressão imuno-histoquímica dos fatores de crescimento. RESULTADOS: IGF-1: Houve 7 casos positivos (29,2 por cento). Houve correlação direta com o CAS (clinical activity score) elevado em todos os casos e em que consideramos CAS apenas acima de 5, em 54,5 por cento. FGF: Houve expressão em 5 casos (20,8 por cento) com relação direta com CAS elevado em todos os casos e em que consideramos CAS maior que 5 (45,4 por cento). VEGF: Houve dois casos positivos (8,3 por cento) para VEGF nas células endoteliais e estes casos também apresentavam CAS maior que 5. A imunorreatividade foi negativa em todo grupo controle. CONCLUSÃO: Todos os pacientes, com exceção de um, com expressão positiva para FGF, IGF-1 e VEGF mostraram CAS maior que 5, sugerindo importante papel destes fatores de crescimento na patogênese e gravidade da oftalmopatia de Graves. Entretanto, a análise estatística demonstrou associação significativa entre IGF-1 e o sexo masculino (P=0,034). Baixa refletividade ao ultra-som e condição endócrina não estiveram correlacionadas.

RESUMO

PURPOSE: To study the applicability (sensitivity, specificity) of polymerase chain reaction (PCR) tests in the detection of cytomegalovirus (CMV), herpes virus (HSV) and varicella zoster (VZV), Epstein-Barr virus (EBV), Mycobacterium sp and Toxoplasma gondii in the diagnosis of patients with or without AIDS, with presumably infectious uveitis, using serum, aqueous humor and vitreous humor samples. METHODS: Twenty individuals with uveitis of presumed infectious origin were evaluated. Sixteen of them had AIDS, four were immunocompetent individuals. We also evaluated 4 normal controls who underwent vitrectomy surgery. Clinical evaluation of the patients was performed together by three clinicians. PCR evaluations of the serum, aqueous, and vitreous humor were performed in a masked fashion by the laboratory staff. RESULTS: Twelve patients had a clinical diagnosis of CMV retinitis. Of these 6 (50%) had a positive PCR for CMV in the vitreous, three (25%) had a positive PCR for CMV in the serum, and none were positive in the aqueous. Five patients had a clinical diagnosis of acute retinal necrosis (ARN). Three (60%) of these had positive PCR for HSV/VZV in the vitreous. One of these patients had a positive PCR reaction for both EBV and HSV/VZV in the vitreous samples. One patient with cutaneous herpes zoster had a positive PCR reaction for HSV/VZV in the serum. Four patients had a presumed diagnosis of ocular toxoplasmosis, one patient (25%) had a positive PCR for Toxoplasma gondii in the serum, 3 (75%) had positive results in the aqueous, and 2 (50%) had positive results in the vitreous. One patient with presumed ocular tuberculosis had a positive PCR reaction both in the serum and in the vitreous samples. Finally, none of the four control individuals revealed any positive PCR reaction. CONCLUSION: PCR is an auxiliary diagnostic procedure that should be evaluated together with ophthalmological aspects of the patient.

OBJETIVOS: Avaliar a aplicabilidade (especificidade, sensibilidade) do teste da reação da cadeia de polimerase (PCR) na detecção de citomegalovírus (CMV), herpes vírus e varicela zoster (HSV, VZV), Epstein-Barr vírus (EBV), Mycobacterium sp e Toxoplasma gondii no diagnóstico de pacientes com ou sem AIDS, com uveíte infecciosa presumível, utilizando amostras de humor aquoso, humor vítreo e soro. MÉTODOS: Vinte pacientes com uveíte infecciosa presumível foram estudados. Dezesseis destes apresentavam AIDS e quatro eram imunocompetentes. Foram utilizados quatro pacientes como grupo controle que se submeteram a vitrectomia. A avaliação clínica foi feita conjuntamente com três oftalmologistas. O exame do PCR do soro, aquoso e vítreo foi feito sem o conhecimento da hipótese diagnóstica pela equipe do laboratório. RESULTADOS: Doze pacientes tinham o diagnóstico clínico de retinite por CMV. Deste subgrupo 6 (50 por cento) eram PCR positivo para CMV no vítreo, 3 (25 por cento) eram PCR positivos para CMV no soro e nenhum destes foi positivo no aquoso. Cinco pacientes tinham o diagnóstico clínico de necrose aguda de retina (ARN). Três (60 por cento) destes eram PCR positivos para HSV/VZV no vítreo. Um destes pacientes era PCR positivo tanto para EBV e HSV/VZV na amostra do vítreo. Um destes pacientes com herpes zoster cutâneo era PCR positivo para HSV/VZV no soro. Quatro pacientes tinham o diagnóstico de toxoplasmose ocular presumida, um paciente (25 por cento) era PCR positivo para Toxoplasma gondii no soro, 3 (75 por cento) eram positivos no aquoso e 2 (50 por cento) eram positivo no vítreo. Um paciente com tuberculose ocular presumível era PCR positivo tanto no soro quanto no vítreo. Nenhum dos pacientes do grupo controle era PCR positivo em qualquer amostra. CONCLUSÃO: O exame do PCR é procedimento diagnóstico auxiliar que deve ser utilizado conjuntamente com os aspectos clínicos.
