RESUMO

PURPOSE: Vitamin D deficiency has been associated with higher rates of autoimmune disease, including noninfectious uveitis. This PRISMA-compliant review and meta-analysis aimed to analyze the correlation between noninfectious uveitis and vitamin D levels. METHODS: We searched PubMed, Embase, Cochrane, and Web of Science databases for studies, published in English, assessing vitamin D levels in patients diagnosed with noninfectious uveitis. The outcomes of interest were vitamin D deficiency, vitamin D mean level, vitamin D supplementation, and smoking rates. A subgroup analysis of inactive uveitis and active uveitis was performed. The heterogeneity was assessed with Cochrane Q-test and I2 statistics; p > 0.10 and I2 > 50% were considered significant for heterogeneity. Statistical analysis was conducted using Review Manager 5.3. RESULTS: 9 studies were included in the meta-analysis comprising a total of 10 711 patients, of whom 1,368 were diagnosed with noninfectious uveitis. Patients with noninfectious uveitis had worse results regarding vitamin D deficiency when compared with the control group (OR 0.58; CI 95% 0.44 to 0.77; p = 0.0002; I2 = 61%). Patients with inactive uveitis had better results towards vitamin D deficiency when compared with active uveitis (OR 5.00; CI 95% 2.84 to 8.81; p < 0.001; I2 = 0%). CONCLUSION: Our research supports the increasing evidence that associates vitamin D deficiency with noninfectious uveitis and its activity. Further investigation into the efficacy of vitamin D screening and supplementation in reducing the recurrence of uveitis is necessary.

RESUMO

PURPOSE: This study aimed to investigate the correlation between serum vitamin D levels and disease activity in patients with noninfectious uveitis. METHODS: We conducted a prospective case-control study, assessing 51 patients with noninfectious uveitis, categorized into active (n=22) and inactive (n=29) groups, along with 51 healthy controls. Serum 25-hydroxy vitamin D [25(OH)D] levels were measured. The uveitis group also completed a questionnaire regarding sunlight exposure habits and vitamin D supplementation. RESULTS: Patients with inflammation-related uveitis exhibited low serum 25(OH)D levels in 68% of cases. The median 25(OH)D level in patients with active uveitis was 17.8 ng/mL (interquartile range [IQR], 15-21 ng/mL), significantly lower compared to the 31.7 ng/mL (IQR, 25-39 ng/mL) in patients with inactive uveitis (p<0.001) and the 27 ng/mL (IQR, 23-31 ng/mL) in the Control Group (p<0.001). Significantly, nearly all patients with uveitis taking vitamin D supplementation were in the Inactive Group (p<0.005). Moreover, reduced sunlight exposure was associated with active uveitis (p<0.003). Furthermore, patients with 25(OH)D levels below 20 ng/mL had ten times higher odds of developing active uveitis (p=0.001). CONCLUSIONS: This study revealed a prevalent 25(OH)D deficiency among patients with noninfectious uveitis and suggested a link between low 25(OH)D levels and disease activity. To prevent future episodes of intraocular inflammation, vitamin D supplementation and controlled sunlight exposure could be viable options.

RESUMO

As complicações associadas à COVID-19 incluem insuficiência renal, miocardite, eventos trombóticos e retinite. No entanto, outras manifestações, como a artrite reativa, também parecem estar atreladas a este vírus e precisam ser mais bem investigadas. O caso relatado se refere a uma paciente de 32 anos, do sexo feminino, na cidade do Rio de Janeiro (RJ), que desenvolveu um quadro de artrite reativa após 5 dias da manifestação de sintomas gripais. Foram realizados exames laboratoriais, GeneXpert para COVID-19 e punção do líquido sinovial. Observou-se GeneXpert positivo para COVID-19, aumento nos marcadores inflamatórios, marcadores sorológicos de autoimunidade não reagentes e cultura negativa no líquido sinovial. Esses resultados descartam artrite séptica, bem como artrite reumatoide, passando a ser considerado o quadro de artrite pós-infecciosa decorrente do SARS-CoV-2.


Complications associated with COVID-19 include renal failure, myocarditis, thrombotic events, and retinitis. However, other manifestations, such as reactive arthritis, also seem to be associated with infection and require further investigation. We report the case of a 32-year-old woman in Rio de Janeiro, RJ who developed reactive arthritis 5 days after the onset of flulike symptoms. Laboratory tests, GeneXpert for COVID-19, and synovial fluid puncture were performed. Positive GeneXpert results for COVID-19, increased inflammatory markers, non-reactive serological markers of autoimmunity, and negative culture in synovial fluid were observed. These results ruled out both septic arthritis and rheumatoid arthritis, leading to a diagnosis of postinfectious arthritis resulting from SARS-CoV-2.

RESUMO

In the present study, the levels of serum and airway soluble chemokines, pro-inflammatory/regulatory cytokines, and growth factors were quantified in critically ill COVID-19 patients (total n=286) at distinct time points (D0, D2-6, D7, D8-13 and D>14-36) upon Intensive Care Unit (ICU) admission. Augmented levels of soluble mediators were observed in serum from COVID-19 patients who progress to death. An opposite profile was observed in tracheal aspirate samples, indicating that systemic and airway microenvironment diverge in their inflammatory milieu. While a bimodal distribution was observed in the serum samples, a unimodal peak around D7 was found for most soluble mediators in tracheal aspirate samples. Systems biology tools further demonstrated that COVID-19 display distinct eccentric soluble mediator networks as compared to controls, with opposite profiles in serum and tracheal aspirates. Regardless the systemic-compartmentalized microenvironment, networks from patients progressing to death were linked to a pro-inflammatory/growth factor-rich, highly integrated center. Conversely, patients evolving to discharge exhibited networks of weak central architecture, with lower number of neighborhood connections and clusters of pro-inflammatory and regulatory cytokines. All in all, this investigation with robust sample size landed a comprehensive snapshot of the systemic and local divergencies composed of distinct immune responses driven by SARS-CoV-2 early on severe COVID-19.

RESUMO

ABSTRACT Purpose: The aim of this study was to describe the epidemiological profile of uveitis cases treated at University Hospital Clementino Fraga Filho and to identify the presentation pattern of intraocular inflammation on the basis of clinical, anatomical, etiological, and demographic criteria. Methods: A retrospective study was conducted using data from the medical records of 408 patients with active disease who attended the ophthalmology service between March and October 2018. Age, sex, visual acuity at the time of diagnosis, anatomical and etiological diagnoses, the clinical aspect, and the main symptoms reported during anamnesis were described. Results: Of the 408 patients in the study, 52% were male and 48% were female. The patients' mean age was 42 years, and most (84%) were between 19 and 64 years old. Anterior uveitis was observed in 37.75% of the patients; posterior uveitis, in 49.75%; panuveitis, in 4.66%; and intermediate uveitis, in 3.43%. Only 18 patients (4.41%) presented with scleritis. Of the 390 patients with anatomical classifications, 76% had known etiologies, with the most prevalent diagnoses being toxoplasmosis (35.4%), followed by juvenile idiopathic arthritis (6.4%), ankylosing spondylitis (5.9%), and syphilis (4.9%). Infectious uveitis corresponded to 49.7% of the patients, while 26.6% of the cases were of noninfectious origin. Anterior uveitis had the highest number of cases classified as idiopathic (49.4%). In the cases of posterior uveitis, the etiology was established 94% of the time. The most frequent symptoms were ocular pain (71.8%) and blurring vision (56.8%). Conclusions: The present study confirmed the historical importance of infectious uveitis in our population, especially ocular toxoplasmosis. Uveitis appears to have no predilection for sex but mainly affects young people of working age, thus generating social and economic consequences. Despite the evolution of diagnostic methods, idiopathic uveitis remains one of the major etiologies. Epidemiological studies point to different presentation patterns of uveitis in different populations, but these may reflect the distinct characteristics of each institution.


RESUMO Objetivo: Descrever o perfil epidemiológico das uveítes atendidas no Hospital Universitário Clementino Fraga Filho - UFRJ. Identificando o padrão de apresentação da inflamação intraocular a partir de critérios clínicos, anatômicos, etiológicos e demográficos. Métodos: Estudo retrospectivo, com base em prontuários de 408 pacientes com doença ativa, atendidos no serviço de oftalmologia no período de março a outubro de 2018. Foram descritos a idade, sexo, acuidade visual no momento do diagnóstico, diagnóstico anatômico e etiológico, aspecto clínico, além dos principais sintomas relatados durante a anamnese. Resultados: Dos 408 pacientes do estudo, 52% eram do sexo masculino e 48% do feminino. A idade média dos pacientes foi de 42 anos, a maioria (84%) entre 19 e 64 anos. Uveíte anterior foi observada em 37,75% dos pacientes, uveíte posterior em 49,75%, panuveíte em 4,66% e uveíte intermediária em 3,43%; apenas 18 pacientes (4,41%) apresentaram diagnóstico de esclerite. Dos 390 pacientes com classificação anatômica, a etiologia foi determinada em 76% deles, com os diagnósticos mais prevalentes sendo Toxoplasmose (35,4%), artrite idiopática juvenil (6,4%), espondilite anquilosante (5,9%) e sífilis (4,9%). ) A uveíte infecciosa correspondeu a 49,7% desses pacientes, enquanto 26,6% eram de origem não infecciosa. A uveíte anterior teve o maior número de casos classificados como idiopáticos (49,4%), enquanto a uveíte posterior teve a etiologia estabelecida em 94% das vezes. Os sintomas mais frequentes foram dor ocular (71,8%) e visão embaçada (56,8%). Conclusões: O presente estudo confirmou a importância histórica da uveíte infecciosa em nossa população, principalmente a toxoplasmose ocular. As uveítes parecem não ter predileção por sexo, mas afetam principalmente jovens em idade ativa, gerando consequências sociais e econômicas. Apesar da evolução nos métodos diagnósticos, a uveíte idiopática continua sendo uma das principais causas. Estudos epidemiológicos apontam para diferentes padrões de uveíte nas populações, estes podem refletir características particulares de cada instituição.

RESUMO

Purpose: To evaluate and establishe the number of patients with ocular manifestations in the early phase of systemic COVID-19 infection.Methods: A cross-sectional study was performed in a COVID-19 referral center regarding ocular findings in patients with COVID-19 in the first few days of the disease. The patients were submitted to a clinical examination, an ophthalmic exam and a RT-PCR for SARS-COV-2.Results: Out of 1740 patients, we reported 108 patients with ocular manifestations. Forty-nine with markedly conjunctivitis had conjunctival swab positive for SARS-COV-2, four of them developed keratitis. There were mostly no evidence of retinopathy nor decrease in visual acuity. They had no marked clinical symptoms, which can contribute and demonstrate that the virus may cause ocular disease as an only finding or in the very early stage of the infection.Conclusion: Patients were in the first days of COVID-19 infection, presented ocular manifestations suggested to be related to the virus and need to be aware of the pathways of transmissions.

RESUMO

Resumo A Síndrome de Blau é uma doença de caráter hereditário autossômico dominante a qual também pode ocorrer de forma esporádica via mutação "de novo". Em geral, tem aparecimento precoce ainda na primeira infância e sua tríade clássica inclui artrite, dermatite e uveíte. Este trabalho visa relatar as manifestações clínicas e principalmente oftalmológicas de uma paciente diagnosticada com Síndrome de Blau com ênfase ao achado incomum de infiltrados corneanos subepiteliais, raramente descrito na literatura.


Abstract The Blau syndrome is an autosomal dominant hereditary disease which can also occur sporadically via "de novo" mutation. Overall it has early onset and its classic triad includes arthritis, dermatitis and uveitis. This paper describes clinical and mainly especially ophthalmologic manifestations of a patient diagnosed with Blau syndrome with emphasis on an uncommon finding of corneal subepithelial infiltrates, rarely described in the literature.
