RESUMO

Infectious bovine keratoconjunctivitis (IBK) is an ocular disease that affects bovines and has significant economic and health effects worldwide. Gram negative bacteria Moraxella bovis and Moraxella bovoculi are its main etiological agents. Antimicrobial therapy against IBK is often difficult in beef and dairy herds and, although vaccines are commercially available, their efficacy is variable and dependent on local strains. The aim of this study was to analyze for the first time the genomes of Uruguayan clinical isolates of M. bovis and M. bovoculi. The genomes were de novo assembled and annotated; the genetic basis of fimbrial synthesis was analyzed and virulence factors were identified. A 94% coverage in the reference genomes of both species, and more than 80% similarity to the reference genomes were observed. The mechanism of fimbrial phase variation in M. bovis was detected, and the tfpQ orientation of these genes confirmed, in an inversion region of approximately 2.18kb. No phase variation was determined in the fimbrial gene of M. bovoculi. When virulence factors were compared between strains, it was observed that fimbrial genes have 36.2% sequence similarity. In contrast, the TonB-dependent lactoferrin/transferrin receptor exhibited the highest percentage of amino acid similarity (97.7%) between strains, followed by cytotoxins MbxA/MbvA and the ferric uptake regulator. The role of these virulence factors in the pathogenesis of IBK and their potential as vaccine components should be explored.

RESUMO

ABSTRACT Purpose: The prevalence of ocular allergy varies according to the population and location of the study. Severe forms of ocular allergy are associated with compromised quality of life. In this study, we aimed to evaluate the application of the Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire to children and adolescents with different subtypes of allergic conjunctivitis. Method: A total of 48 patients (aged 5-12 years) with allergic conjunctivitis were included in this study. They were enrolled and monitored at a specialized center. After the clinical appointment, the children responded to the questionnaire on two occasions at an interval of 30 days. Individual scores (ranging from 0 to 3) of the 16 items were added. Results: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire demonstrated good translation, adaptation, and intellectual properties, with substantial internal consistency (Cronbach's α coefficient = 0.702). There was no significant difference between the responses of the two interviews, revealing good reproducibility. The moderate/severe forms of allergic conjunctivitis had significantly higher quality of life scores (indicating a poorer quality of life) than the mild forms. Conclusions: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis proved to be quick, reliable, and reproducible for assessing the quality of life in children with allergic conjunctivitis. However, its ability to detect changes resulting from symptom aggravation or treatment needs to be further evaluated.

RESUMO

ABSTRACT Purpose: This clinical study compared autologous serum eye drops diluted with 0.5% methylcellulose and 0.9% saline solution. The subjective criteria for symptom improvement and the objective clinical criteria for response to therapy were evaluated. Methods: This longitudinal prospective study enrolled 23 patients (42 eyes) with persistent epithelial defects or severe dry eye disease refractory to conventional therapy who had been using autologous serum 20% prepared with methylcellulose for > 6 months and started on autologous serum diluted in 0.9% saline solution. The control and intervention groups consisted of the same patients under alternate treatments. The subjective criteria for symptom relief were evaluated using the Salisbury Eye Evaluation Questionnaire. The objective clinical criteria were evaluated through a slit-lamp examination of the ocular surface, tear breakup time, corneal fluorescein staining, Schirmer's test, rose Bengal test, and tear meniscus height. These criteria were evaluated before the diluent was changed and after 30, 90, and 180 days. Results: In total, 42 eyes were analyzed before and after 6 months using autologous serum diluted with 0.9% saline. No significant differences were found in the subjective criteria, tear breakup time, tear meniscus, corneal fluorescein staining, or rose Bengal test. Schirmer's test scores significantly worsened at 30 and 90 days (p=0.008). No complications or adverse effects were observed. Conclusions: This study reinforces the use of autologous serum 20% as a successful treatment for severe dry eye disease resistant to conventional therapy. Autologous serum in 0.9% saline was not inferior to the methylcellulose formulation and is much more cost-effective.

RESUMO Objetivo: Este estudo comparou o colírio de soro au tólogo manipulado com metilcelulose a 0,5% com solução salina 0,9%. Critérios subjetivos de melhora dos sintomas e critérios clínicos objetivos para resposta à terapia foram avaliados. Métodos: Este estudo prospectivo longitudinal envolveu 23 pacientes (42 olhos) com defeitos epiteliais persistentes ou doença de olho seco grave refratária à terapia convencional que usavam colírio de soro autólogo 20% preparado com metilcelulose por mais de 6 meses e iniciaram soro autólogo diluído em solução salina 0,9%. Os grupos controle e intervenção consistiam dos mesmos pacientes sob tratamentos alternados. Os critérios subjetivos para o alívio dos sintomas foram avaliados usando o Salisbury Eye Evaluation Questionnaire. Os critérios objetivos foram avaliados por meio de exame em lâmpada de fenda incluindo: tempo de ruptura da lágrima, coloração da córnea com fluoresceína, teste de Schirmer, coloração com rosa bengala e altura do menisco lacrimal. Esses critérios foram avaliados antes da troca do diluente e após 30, 90 e 180 dias. Resultados: Um total de 42 olhos foram analisados antes e após 6 meses usando soro autólogo diluído com solução salina 0,9%. Nenhuma diferença significativa foi encontrada nos critérios subjetivos, tempo de ruptura da lágrima, menisco lacrimal, coloração com fluoresceína ou rosa bengala. Os resultados dos testes de Schirmer pioraram significativamente em 30 e 90 dias (p=0,008). Não foram observadas complicações ou efeitos adversos. Conclusões: Este estudo reforça o uso do colírio de soro autólogo 20% como um tratamento de sucesso para a doença do olho seco grave resistente à terapia convencional. O soro autólogo diluído em solução salina a 0,9% não foi inferior à formulação de metilcelulose.

RESUMO

ABSTRACT Purpose: To compare strip meniscometry and Schirmer tear test 1 results and tear film breakup time between dogs with normal eyes and dogs diagnosed with keratoconjunctivitis sicca. Methods: One-hundred fifty-six eyes of 78 dogs, 88 normal eyes, and 68 eyes diagnosed with keratoconjunctivitis sicca were included in the study. The tests were performed in the following sequence: Schirmer tear test 1 was used to allocate the dogs to the normal or keratoconjunctivitis sicca group, followed by the strip meniscometry test and tear film breakup time measurement. Results: The results (mean ± standard deviation) of the tests in the normal group were as follows: Schirmer tear test 1, 22.75 ± 3.88 mm/min; strip meniscometry test, 10.01 ± 2.35 mm/5 sec; and tear film breakup time, 25.82 ± 5.47 sec. In the keratoconjunctivitis sicca group, the results were as follows: Schirmer tear test 1, 6.10 ± 4.44 mm/min; strip meniscometry test, 3.03 ± 2.62 mm/5 sec; and tear film breakup time, 10.78 ± 4.23 sec. The Spearman correlation coefficient in the keratoconjunctivitis sicca group was very high, with a significant difference between the strip meniscometry test and Schirmer tear test 1 (r=0.848, p<0.001), and moderate and significant between the strip meniscometry test and tear film breakup time (r=0.773, p<0.001). The cutoff for the strip meniscometry test for keratoconjunctivitis sicca was 7.0 mm/5 sec. Keratoconjunctivitis sicca was suspected when the values were <10 mm/5 sec. Conclusions: This study provided strip meniscometry test values from dogs with normal eyes and eyes with keratoconjunctivitis sicca, with high sensitivity and specificity compared with those of the Schirmer tear test 1. In the future, the strip meniscometry test may be another important quantitative test and could complement the gold standard Schirmer tear test for the diagnosis of keratoconjunctivitis sicca in dogs, an excellent animal model for the study of the disease.

RESUMO Objetivo: Comparar o teste de meniscometria em tira com o teste lacrimal de Schirmer 1 e o tempo de ruptura do filme lacrimal, em cães com olhos normais e cães com diagnóstico de ceratoconjuntivite seca. Métodos: Cento e cinquenta e seis olhos de 78 cães, 88 olhos normais e 68 olhos com diagnóstico de ceratoconjuntivite seca. Os testes foram realizados na seguinte sequência: o teste lacrimal de Schirmer 1 foi utilizado para alocar os cães no grupo normal ou no grupo ceratoconjuntivite seca, seguido pelo teste de meniscometria em tira e tempo de ruptura do filme lacrimal. Resultados: As médias e desvios-padrão para os olhos normais foram: teste lacrimal de Schirmer 1 = 22,75 ± 3,88 mm / min; teste de meniscometria em tira = 10,01 ± 2,35 mm / 5 seg; tempo de ruptura do filme lacrimal = 25,82 ± 5,47 seg; e para os olhos do grupo ceratoconjuntivite seca foram: teste lacrimal de Schirmer 1 = 6,10 ± 4,44 mm / min; teste de meniscometria em tira = 3,03 ± 2,62 mm / 5 seg; tempo de ruptura do filme lacrimal = 10,78 ± 4,23 seg. O teste de correlação de Spearman no grupo ceratoconjuntivite seca foi muito alto, com diferença significativa entre teste de meniscometria em tira e teste lacrimal de Schirmer 1 (r=0,848, p<0,001), moderada e significativa entre teste de meniscometria em tira e tempo de ruptura do filme lacrimal (r=0,773, p<0,001). O cut-off para teste de meniscometria em tira para ceratoconjuntivite seca foi identificado em 7,0 mm / 5 seg, valores abaixo de 10 mm / 5 seg podem ser considerados suspeitos para KCS. Conclusões: Este estudo forneceu valores de teste de meniscometria em tira em olhos normais e com ceratoconjuntivite seca em cães, revelando alta sensibilidade e especificidade em comparação com o teste lacrimal de Schirmer 1. No futuro, o teste de meniscometria em tira pode ser outro teste quantitativo importante e pode complementar o teste lacrimal de Schirmer padrão ouro para o diagnóstico de ceratoconjuntivite seca em cães, um excelente modelo animal para o estudo de ceratoconjuntivite seca.

RESUMO

Background and Aim: Keratoconjunctivitis sicca (KCS) is predominantly an immune-mediated chronic inflammatory ocular disease that is commonly diagnosed in dogs. This study aimed to compare the conventional use of topical immunosuppressant tacrolimus 0.03% eye drops and a new therapy injectable homologous platelet-rich plasma (HPRP) into the third eyelid gland and inferior and superior palpebral conjunctiva of dogs with KCS. Materials and Methods: A total of 66 eyes from 33 dogs were evaluated. The eyes were divided into three equal groups: Negative control group, tacrolimus group (TG), and homologous platelet-rich plasma group (HPRPG). The animals were evaluated using the Schirmer's tear test-1 (STT-1), osmolarity test (OT), strip meniscometry test (SMT), tear film break-up test (TBUT), fluorescein test, lissamine green test (LGT), and cytological and histopathological analyses. Results: In TG, there was a significant increase (p < 0.05) in the STT-1 and SMT values, and goblet cell count in the palpebral conjunctiva by the end of the study. In HPRPG, 36% (four dogs) received three applications, 55% (six dogs) received two applications, and 9% (one dog) received one application before the initial ocular signs improved. There was a significant decrease (p < 0.05) in the lymphocyte and neutrophil counts of the palpebral conjunctiva in HPRPG than in TG. Both groups showed equivalent improvements in TBUT, OT, and LGT values. Conclusion: Tacrolimus 0.03% eye drops were more efficient than HPRP in increasing tear production and the number of goblet cells. However, injectable HPRP was more efficient than tacrolimus in decreasing the number of conjunctival inflammatory cells. Treatment with injectable HPRP requires an average of two to three applications, is safe and feasible, and can be used as a cheaper alternative or as an adjuvant to conventional treatment with topical immunosuppressants.

RESUMO

Objetivo: Describir el contexto actual de la alergia ocular para la realización de un diagnóstico precoz, una identificación temprana de los subtipos, un adecuado manejo terapéutico y un control de la severidad. Métodos: Se realizó una búsqueda sistemática de la literatura científica de mayor impacto con el uso de las palabras clave. Se limitó la búsqueda por tipo de diseño (revisiones, series de casos, estudios descriptivos, analíticos y experimentales, metaanálisis). No se tuvo en cuenta el idioma de la publicación. Las bases de datos utilizadas fueron: PubMed, Ebsco Host, Lilacs y Science Direct. Se identificaron y se evaluaron 114 artículos, de los cuales se seleccionaron 24 por su pertinencia para el estudio. Conclusiones: La alergia ocular es uno de los trastornos oculares más comunes encontrados en las consultas pediátricas y oftalmológicas. Si bien en la mayoría de los casos se trata de formas leves, estas pueden interferir en la calidad de vida del paciente. Es importante que estos pacientes con manifestaciones oftalmológicas de alergia se remitan al alergólogo para detectar otra patología, que, asociada al padecimiento alérgico, origine los síntomas que suelen ser graves, con una duración y frecuencia importantes(AU)

Introduction: Allergy is the most common disorder of the immune system. In recent decades, the prevalence of allergic diseases has increased considerably in all countries. Objective: To describe the current context of ocular allergy in order to make an early diagnosis, an early identification of subtypes, establish an adequate therapeutic management and control of severity. Methods: A systematic search of the scientific literature with the highest impact was performed using keywords. The search was limited by type of design (reviews, case series, descriptive, analytical and experimental studies, meta-analysis). The language of the publication was not taken into account. The databases used were: PubMed, Ebsco Host, Lilacs and Science Direct. A total of 114 articles were identified and evaluated, of which 24 were selected for their relevance to the study. Conclusions: Ocular allergy is one of the most common ocular disorders encountered in pediatric and ophthalmology consultations. Although in most cases these are mild forms, they can interfere with the patient's quality of life. It is important that these patients with ophthalmologic manifestations of allergy are referred to the Allergist to detect other pathology, which associated with the allergic condition originate the symptoms that are usually severe, with a significant duration and frequency(AU)

RESUMO

This study analyzed clinical and cyto-histomorphological parameters of the ocular surface of Shih Tzu dogs, non-carriers and carriers of quantitative keratoconjunctivitis sicca (KCS) at different stages. Thirty-five eyes from 23 male and female Shih Tzu dogs between two and eight years were evaluated in four groups: control group (CG - without KCS), mild KCS group (KCS1), moderate KCS group (KCS2), and severe KCS group (KCS3). Most clinical variables among KCS carrier groups worsened at the more advanced stages of the disease, with a negative correlation between the Schirmer tear test (STT-1) and tear film break-up time (TBUT). Squamous metaplasia, lymphoplasmacytic inflammatory infiltrate, and decrease in conjunctival goblet cells on histopathological examination comprised disease severity parameters. Quantitative KCS non-carried Shih Tzu dogs have qualitative and tear film distribution changes. The cytomorphological exam is limited to evaluating the inflammatory infiltrate and quantifying conjunctival goblet cells. However, intermediate epithelial cells were higher in healthy eyes compared to eyes with KCS in Shih Tzu dogs. Also, moderate and severe KCS carrier Shih Tzu dogs have qualitative dysfunction of the tear film. KCS in Shih Tzu dogs is common and chronic and may be responsible for the loss of vision of these animals. Early identification of the disease and routine evaluation can improve these dogs' quality of life and ocular health.

Este estudo analizou os parâmetros clinicos e cito-histomorfológicos da superfície ocular de cães da raça Shih Tzu, portadores e não portadores de ceratoconjuntivite seca quantitative (CCS) em diferentes estágios. Trinta e cinco olhos de 23 cães da raça Shih Tzu, machos e fêmeas, entre as idades de dois e oito anos foram avaliados em quatro grupos: grupo controle (GC - sem CCS), grupo CCS inicial (CCS1), grupo CCS moderada (CCS2) e grupo CCS severa (CCS3). A maioria das variáveis clínicas dentro os grupos portadores de CCS pioraram a medida que os estágios da doença avançam, com correlações negativas entre o teste lacrimal de Schirmer (TLS) e o tempo de ruptura do filme lacrimal (TRFL). Metaplasia escamosa, infiltrado inflamatório linfoplasmocítico e diminuição das células caliciformes no exame histopatológico compreenderam parâmetros de severidade da doença. Cães Shih Tzu não portadores de CCS quantitativa tem alterações qualitativas e na distribuição do filme lacrimal. O exame citomorfológico é limitado para a avaliação do infiltrado inflamatório e quantificação de células caliciformes. Entretanto, células inermediárias epiteliais são mais presents nos olhos saudáveis quando comparados aos olhos portadores de CCS em Shih Tzus. Também, Shih Tzus portadores de CCS nos estágios moderados e severos possuem disfunções qualitativas da lágrima. A CCS em Shih Tzu é comum, crônica e pode ser responsável pela perda de visão dos animais. A identificação precoce da doença e avaliações rotineiras podem aumentar a qualidade de vida e a saúde ocular nesses cães.

RESUMO

El síndrome de Sjögren es la segunda enfermedad autoinmune crónica más prevalente; factores hereditarios y medioambientales interactúan provocando una "epitelitis autoinmune" que daña el tejido glandular exocrino principalmente, pero también a otros órganos; debido a esta heterogeneidad clínica, el diagnóstico y tratamiento constituyen un desafío. Estudios demuestran que afecta al 0,1-0,6 % de la población, con predilección por el sexo femenino (9:1). En Colombia existen pocos estudios epidemiológicos descriptivos y de caracterización en este síndrome. Caracterizar los parámetros clínicos y epidemiológicos de pacientes con síndrome de Sjögren. Se realizó un estudio observacional descriptivo de corte transversal, se revisaron historias clínicas de 409 pacientes con el síndrome que asistieron al Hospital Universitario San Ignacio entre 2012 y 2019. Los datos se analizaron usando estadística descriptiva. La edad promedio de diagnóstico fue 59 años, la relación mujer: hombre 9:1, (91,7 % y 8,3 % respectivamente). Hubo mayor prevalencia en pacientes de 51 a 60 años (131) seguido por los de 61-70 años (114). La manifestación clínica más común fue la xerostomía (90 %); la biopsia de glándula salival menor fue el examen complementario más solicitado (65 %). El compromiso óseo-articular, fue la enfermedad concomitante más asociada. La etiología de la enfermedad es poco conocida, sin embargo, su caracterización, así como la identificación de medios diagnósticos y terapéuticos ayuda en la comprensión de la clínica; dicha información permitirá el desarrollo de tratamientos cada vez más efectivos y específicos.

Sjögren syndrome is the second most common chronic autoimmune disease, environmental and hereditary mechanisms causes an autoimmune epithelitis that affect the exocrine glandular tissue mainly, but also other organs; because this broad spectrum of clinical characteristics, the diagnostic and treatment become a challenge. Studies has shown that 0.1-0.6 % of the population is affected, with predominance of females over males (9:1). In Colombia there are few descriptive epidemiological studies and characterization of the affected population. Clinical and epidemiological characterization of Sjögren syndrome patients. A descriptive cross-sectional observational study was conducted, 409 clinical histories of patients with the syndrome at San Ignacio University Hospital from 2012 to 2019 were analized. The data collected were subjected to a descriptive statistic. The average age of diagnosis was 59 years, the ratio female: male 9:1 (91.7 % and 8.3 % respectively), the highest frequency of the syndrome was found in the 51 to 60 years old group (131) followed by the 61 to 70 years old group (114). The most common clinical manifestation was xerostomia (90 %), minor salivary gland biopsy was the most frequent test requested (65 %). The osseoarticular involvement was the most frecuent concomitant disease. Although the etiology of Sjögren syndrome is little known, its characterization, as well as the identification of the diagnostic and therapeutic means used, is of great help in understanding the disease; this information will allow the development of increasingly effective and specific treatments. More studies are required, in different locations, which will highlight the differences between populations.

RESUMO

ABSTRACT Purpose: Ocular disorders are among the most frequent manifestations of psoriatic arthritis. The incidence, type, and severity of these disorders may be influenced by genetics, local environmental factors, and access to ophthalmic treatment. Here we describe the ocular manifestations of psoriatic arthritis among denizens of the Amazon region of Para, Brazil, treated by the rheumatology service of Universidade do Estado do Pará. Methods: This cross-sectional study examined 23 psoriatic arthritis patients (median age 47.78 years, no sex predominance) diagnosed according to Caspar's criteria. Disease activity was evaluated according to the Clinical Disease Activity Index for Psoriatic Arthritis. Ophthalmological examinations performed included visual acuity with distance correction, biomicroscopy, applanation tonometry, fundoscopy, Schirmer test I, tear breakup time, fluorescein staining, and lissamine green staining. Patients also completed The Ocular Surface Disease Index questionnaire. Results: The most common ophthalmic disorders were dry eye (60.9%), cataracts (56.5%), blepharitis (47.8%), keratitis (43.5%), meibomitis (30.4%), pterygium (26, 1%), and pinguecula (13%). More than half of all patients demonstrated recent onset (>5 years), the peripheral disease type, and severe symptoms according to Clinical Disease Activity Index for Psoriatic Arthritis. Conclusion: The ocular manifestations of psoriatic arthritis are varied and mainly affect the ocular surface. Regular ophthalmological follow-up is recommended for patients in the early stage with high disease activity.

RESUMO Objetivo: Descrever as manifestações oftalmológicas observadas em pacientes com artrite psoriásica atendidos no Serviço de Reumatologia da Universidade do Estado do Pará. Métodos: Estudo transversal. A amostra foi composta por 23 pacientes com artrite psoriásica, segundo os critérios de Caspar, atendidos no ambulatório de reumatologia da Universidade do Estado do Pará.

Resultados: Nesta pesquisa não houve predomínio entre os sexos e a população tinha uma mediana de idade de 47,78 anos. As manifestações mais comuns foram olho seco (60,9%), catarata (56,5%), blefarite (47,8%), ceratite (43,5%), meibomite (30,4%) e pterígio (26,1%). Conclusão: As manifestações oculares encontradas em pacientes com artrite psoriásica são variadas e afetam sobretudo a superfície ocular; no entanto, são clinicamente subestimadas; por isso recomenda-se o acompanhamento oftalmológico regular e periódico para pacientes com artrite psoriásica.

RESUMO

ABSTRACT Purpose: To examine the effect of subepithelial corneal infiltrates on corneal biomechanical properties after epidemic keratoconjunctivitis compared to that in healthy controls. Methods: The cross-sectional study included consecutive patients with bilateral subepithelial corneal infiltrates after epidemic keratoconjunctivitis and healthy controls. Best corrected visual acuity corneal subepithelial infiltrate scoring Fantes grading scale, and central corneal thickness were measured. Corneal hysteresis corneal resistance factor Goldmann correlated intraocular pressure and corneal compensated intraocular pressure were assessed using an ocular response analyzer. Results: This study included 66 eyes of 33 patients with subepithelial corneal infiltrates following epidemic keratoconjunctivitis and randomly selected 37 eyes of 37 healthy volunteers. The mean Fantes and CSIS scores were 1.8 ± 0.8 and 2.9 ± 1.3, respectively, in the first involved eyes and 1.3 ± 1.1 and 1.9 ± 1.7, respectively, in the fellow eyes (p=0.009 and p=0.002, respectively). The first (526.1 ± 28.1 µm; p=0.005) and second involved eyes (523.4 ± 38.1 µm; p=0.044) had significantly thinner corneas compared to that in healthy controls (557.0 ± 38.1 µm). While best-corrected visual acuity showed a positive correlation with corneal resistance factor (r=0.363, p=0.045) and corneal hysteresis (r=0.414, p=0.021), corneal subepithelial infiltrate scoring showed a negative correlation with Goldmann correlated intraocular pressure (r=-0.479, p=0.006) and corneal compensated intraocular pressure (r=-0.413, p=0.021). Conclusion: Eyes with subepithelial corneal infiltrates had significantly thinner corneas compared to that in healthy controls. A positive correlation of the corneal resistance factor and corneal hysteresis with best-corrected visual acuity and a negative correlation of the Goldmann correlated intraocular pressure and corneal compensated intraocular pressure with corneal subepithelial infiltrate scoring should be taken into account when measuring intraocular pressure values in patients with subepithelial corneal infiltrates.

RESUMO Objetivo: Examinar o efeito de infiltrados sub-epiteliais corneanos nas propriedades biomecânicas da córnea após ceratoconjuntivite epidêmica, em comparação com controles saudáveis. Métodos: Este estudo transversal incluiu pacientes consecutivos com infiltrados sub-epiteliais corneanos bilaterais após ceratoconjuntivite epidêmica e controles saudáveis. Foram medidas a melhor acuidade visual corrigida, uma pontuação do infiltrado sub-epitelial da córnea, a escala de graduação de Fantes e a espessura central da córnea. A histerese da córnea, o fator de resistência da córnea, a pressão intraocular correlacionada à tonometria de Goldmann e a pressão intraocular compensada da córnea foram avaliados com o Ocular Response Analyzer. Resultados: Este estudo incluiu 66 olhos de 33 pacientes com infiltrados corneanos sub-epiteliais após ceratoconjuntivite epidêmica e selecionou aleatoriamente 37 olhos de 37 voluntários saudáveis. As pontuações médias da escala de Fantes e dos infiltrados sub-epiteliais corneanos nos primeiros olhos acometidos foram respectivamente de 1,8 ± 0,8 e 2,9 ± 1,3. Nos olhos contralaterais, foram respectivamente de 1,3 ± 1,1 e 1,9 ± 1,7 (p=0,009 e p=0,002, respectivamente). O primeiro e o segundo olhos envolvidos tinham córneas significativamente mais finas (respectivamente 526,1 ± 28,1 µm; p=0,005 e 523,4 ± 38,1 µm; p=0,044) em comparação com os controles saudáveis (557,0 ± 38,1 µm). Embora a acuidade visual melhor corrigida tenha mostrado uma correlação positiva com o fator de resistência da córnea (r=0,363, p=0,045) e com a histerese da córnea (r=0,414, p=0,021), a pontuação dos infiltrados sub-epiteliais corneanos mostrou uma correlação negativa com a pressão intraocular correlacionada à tonometria de Goldmann (r=-0,479, p=0,006) e com a pressão intraocular compensada da córnea (r=-0,413, p=0,021). Conclusão: Os olhos com infiltrados corneanos sub-epiteliais tinham córneas significativamente mais finas em comparação com os controles saudáveis. Ao se medirem os valores de pressão intraocular em pacientes com infiltrados sub-epiteliais corneanos, deve-se levar em consideração tanto as correlações positivas do fator de resistência da córnea e da histerese da córnea com a melhor acuidade visual corrigida quanto as correlações negativas da pressão intraocular correlacionada à tonometria de Goldmann e da pressão intraocular compensada da córnea com a pontuação do infiltrado sub-epitelial da córnea.

RESUMO

INTRODUCTION: This case report describes an 8 year old boy unsuccessfully treated for years for Vernal Keratoconjunctivitis. CASE REPORT: We report a VKC resistant to all types of treatment known in the literature, such as topical and oral corticosteroids, topical and oral cyclosporine, immunotherapy, and third generation anti-histamine eye drops, due to unknown HIV co-infection. During further laboratory tests, patient tested positive for HIV even though he did not present any clinical manifestation of HIV disease. Only after antiretroviral treatment was started the allergy symptoms completely regressed. CONCLUSION: This case report suggests considering investigation of HIV infection in patients with refractory allergic conjunctivitis.

RESUMO

Contexto: As manifestações oculares da artrite reumatoide representam cerca de 40% das manifestações extra-articulares, acarretando comprometimento da qualidade de vida. O fator reumatoide e o anticorpo contra peptídeos citrulinados cíclicos são marcadores sorológicos para diagnóstico laboratorial da doença. Objetivo: Identificar as principais manifestações oculares da artrite reumatoide e a sua relação com a positividade do fator reumatoide e anticorpo contra peptideos citrulinados cíclicos, através de uma revisão sistemática. Métodos: Uma revisão sistemática foi conduzida nas bases de dados: PubMed, Scopus, Web of Science e SciELO, até janeiro de 2018. Critérios de inclusão e exclusão foram aplicados e dados dos estudos selecionados foram extraídos e organizados em tabelas e gráficos. Avaliação metodológica e análise estatística, incluindo duas meta-análises, foram realizadas. Os estudos selecionados foram armazenados no Software Endnote X8 versão student (Serial Number: 3151802521 e Product Key: L899B-8N8FJ-SX9JW-BEQ58-U9HCD). Análises estatísticas foram realizadas com o Software Review Manager versão 5.3 (software gratuito). Resultados: Dos 1.985 estudos encontrados através da busca em bases de dados, quatro estudos foram incluídos. A síndrome sicca e síndrome de Sjögren secundária representaram cerca de 50% das manifestações oculares. Meta-análises aplicadas em dois estudos não identificaram associação de risco estatisticamente significativa entre o anticorpo contra peptideos citrulinados cíclicos e fator reumatoide e o desenvolvimento de manifestações oculares. Conclusão: As manifestações oculares da Artrite Reumatoide correspondem à significativa parcela das manifestações extra-articulares. No entanto, não foram constatadas associação de risco entre autoanticorpos e tais manifestações. [au]

Background: Ocular involvement represents about 40% of extra-articular manifestations of Rheumatoid Arthritis, pointing to impairment in patients' quality of life. Anti-cyclic citrullinated peptide antibody and rheumatoid factor are serological markers to laboratorial diagnosis of disease. Objective: Identify main ocular manifestations of Rheumatoid Arthritis and its relationship between positivity of rheumatoid factor and anti-cyclic citrullinated peptide antibody, through a Systematic Review of literature. Methods: Systematic Review was conducted on database search, including: PubMed, Scopus, Web of Science and SciELO until January, 2018. Inclusion and exclusion criteria were applied and data of select studies were extracted and organized in tables and graphics. Methodological appraisal and statistical analysis, including meta-analyses, were performed. Selected studies were stored in software Endnote X8 student (Serial Number: 3151802521 e Product Key: L899B-8N8FJ-SX9JW-BEQ58-U9HCD). Statistical analyses were performed with Review Manager software version 5.3 (free software). Results: From 1,985 studies found by database search, four studies were selected and analyzed. Sicca syndrome and secondary Sjögren's syndrome represented about 50% of ocular manifestations. Meta-analyses applied in two studies demonstrated no statistical significative risk association between anti-cyclic citrullinated peptide and development of ocular manifestations. Conclusion: From extra-articular manifestations of Rheumatoid Arthritis, ocular manifestations correspond to a significative amount. Nevertheless, there were no statistical significative risk association between autoantibodies and these manifestations. [au]

RESUMO

Introducción: La queratoconjuntivitis seca es una enfermedad de causa multifactorial, que afecta la producción de lágrimas y la superficie ocular, a la vez que ocasiona malestar, visión borrosa e inestabilidad de la película lagrimal. Métodos: Se realizó un estudio descriptivo y transversal de 50 pacientes con diagnóstico de queratoconjuntivitis seca, atendidos en el Centro Oftalmológico del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, desde enero hasta julio de 2020. Objetivo: Caracterizar a los pacientes con queratoconjuntivitis seca según variables epidemiológicas clínicas y oftalmológicas. Resultados: En la serie predominaron las féminas (66,0 %), los pacientes mayores de 60 años (40,0 %), la lectura excesiva como factor de riesgo (42,0 %), la irritación, la fatiga ocular y la visión borrosa como criterios diagnósticos, además de la disminución del tiempo de rotura de la película lagrimal en 68,0 % de la muestra, entre otros resultados. Conclusión: La queratoconjuntivitis seca, desde el punto de vista clínico y epidemiológico fue similar a lo descrito en la bibliografía especializada en cuanto a los grupos de edades, sexo y principales síntomas descritos.

Introduction: The keratoconjunctivitis sicca is a disease of multifactorial cause that affects the production of tears and the ocular surface, at the same time that causes discomfort, blurred vision and instability of the lacrimal thin layer. Methods: A descriptive and cross-sectional study of 50 patients with diagnosis of keratoconjunctivitis sicca, assisted in the Ophthalmolgic Center of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, was carried out from January to July, 2020.

RESUMO

PURPOSE: To establish the prevalence of ocular involvement in a Colombian population with rheumatologic diseases. DESIGN: Observational cross-sectional study. METHODS: We included a probabilistic sample size of 797 patients who attended a rheumatologic disease center in Bogotá, Colombia. Statistical analysis with descriptive measures and Chi-square independence test between rheumatologic diseases and ophthalmological symptoms and diseases was performed. RESULTS: Eighty-four percent of the population were women, and the mean age was 54.61± 15.64 years. The most common condition was rheumatoid arthritis (33.37%), followed by fibromyalgia (22.71%), Sjögren Syndrome (19.72%), and systemic lupus erythematosus (9.91%). Almost 7% of the patients presented polyautoimmunity. Thirty-five percent of the patients reported one or more ophthalmological symptoms, being dry eye sensation the most common (30.86%), followed by ocular pain (2.76%), red-eye, and decreased visual acuity (both 2.63%). Similarly, 21.45% of the patients presented one or more ophthalmological diagnoses, being keratoconjunctivitis sicca the most common (15.93%), followed by cataract, uveitis (1.38% each), and scleritis (1.25%). CONCLUSION: Almost a third of the patients reported any ocular involvement. It is crucial to be aware of the most common ophthalmic manifestations among the different rheumatologic diseases in our population, to offer early specialist referral and timely treatment.

RESUMO

Infectious keratoconjunctivitis (IKC) is the most frequent ocular disease in livestock worldwide and is primarily caused by Moraxella bovis, M. ovis, and/or M. bovoculi. The economic impact of IKC is mainly due to ocular damage, which leads to weight loss, management difficulties, pain and discomfort, and cost of treatments. In horses, limited information is available on the association of Moraxella spp. with keratoconjunctivitis. The present report describes two cases of equine keratoconjunctivitis caused by members of the genus Moraxella. Both animals presented with lacrimation, conjunctivitis, photophobia, mucoid or purulent secretions, blepharitis, and conjunctival hyperemia. The diagnosis of IKC was based on the epidemiological and clinical findings; the etiological agent was identified through bacteriological (culture and biochemistry assays) and molecular testing (PCR and nucleotide sequencing). Our study reports the isolation of Moraxella bovoculi (SBP 88/19) and a putative new species/mutant of Moraxella (SBP 39/19) recovered from ocular secretions in horses. Thus, we suggest the inclusion of Moraxella spp. infection in the differential diagnosis of conjunctivitis in horses in Southern Brazil.

RESUMO

Abstract Background: The most common ocular disease affecting cattle worldwide is infectious bovine keratoconjunctivitis (IBK), which has been associated with Moraxella bovis bacterium. Objective: To report the molecular characterization of the ocular bacterial microbiota and its relation to IBK in cattle in two dairy regions in Michoacán, Mexico. Methods: A total population of 761 bovines were evaluated, of which 17 (2.23%) showed symptoms of IBK. Thirty-eight bacterial isolates from ocular samples of bovines with IBK were characterized by Gram-staining and antimicrobial sensitivity. In addition, isolates were identified by sequence comparisons of the 16S ribosomal gene. Results: The genus Moraxella was one of the most abundant bacteria and M. bovoculi was the most predominant species. Conclusion: The bacterial isolates identified in eye lesions of cattle and associated to IBK are diverse. To the author´s knowledge, this is the first study on the subject in Mexico; therefore, more research is needed to estimate the incidence of IBK and determine its associated microbiota.

Resumen Antecedentes: la enfermedad ocular más común que afecta al ganado en todo el mundo es la queratoconjuntivitis infecciosa bovina (IBK), que se ha asociado con la bacteria Moraxella bovis. Objetivo: reportar la caracterización molecular de la microbiota bacteriana ocular y su relación con IBK en ganado de dos regiones lecheras en Michoacán, México. Métodos: se evaluó una población total de 761 bovinos de los cuales 17 (2,23%) mostraron síntomas de IBK. Se obtuvieron treinta y ocho aislamientos bacterianos de muestras oculares de bovinos con IBK, los cuales se caracterizaron por tinción de Gram y sensibilidad antimicrobiana. Además, los aislamientos se identificaron mediante comparaciones de secuencias del gen ribosomal 16S. Resultados: el género Moraxella fue una de las bacterias más abundantes y M. bovoculi fue la especie más predominante. Conclusión: los aislamientos bacterianos identificados en lesiones oculares de bovinos y asociados a IBK son diversos. Hasta donde sabemos, este es el primer estudio sobre el tema realizado en México; por lo tanto, es necesario ampliar esta investigación para estimar la incidencia de IBK y determinar la microbiota asociada con la misma.

RESUMO

Two outbreaks of traumatic injuries in goats and sheep associated with grazing and ingestion of the cactus Tacinga inamoena have recently been reported in the state of Paraíba, Brazil. In the first of these, which was detected in 2019 during a preliminary inspection of a herd of 70 animals, it was found that 15 showed certain ocular complications, and these animals were subjected to general physical and ophthalmic examinations. The clinical findings included excessive lacrimation, blepharitis, photophobia, corneal opacity, hyphema, corneal neovascularization, corneal ulcers, and adherence of gloquids to the bulbar conjunctiva and cornea. Large amounts of T. inamoena were found to be present in several areas in which these animals had been grazed and had been observed consuming the fruits of this plant. In the second outbreak during the following year, two sheep from a total of 100 animals were identified as having oral lesions associated with grazing in areas within which T. inamoena was growing. One of these animals was referred to a veterinary hospital, and on physical examination was found to show apathy, anorexia, a body score of 1.5, and the presence of gloquids within the fur. With respect to the oral cavity, halitosis, severe sialorrhea, extensive hemorrhagic ulcers, and painful tenderness on palpation were detected. Given the unfavorable prognosis, the sheep was subsequently euthanized. At necropsy, multifocal to coalescent plaques were detected on the upper and lower lips, oral mucosa, tongue, and hard and soft palates. These were generally elevated and firm and characterized by an irregular, ulcerated surface, sometimes crusty, with a yellow to light brown center and erythematous edges. The findings of this study highlight that the consumption of T. inamoena can cause serious oral and ophthalmic lesions in small ruminants in the northeastern semi-arid regions of Brazil, and can potentially contribute to substantial large economic losses. This problem tends to be exacerbated by the invasive behavior of T. Inamoena, particularly in areas in the process of environmental degradation.(AU)

Relatam-se dois surtos de lesões traumáticas associadas ao pastejo e ingestão da Tacinga inamoena por caprinos e ovinos no estado da Paraíba, Brasil. No primeiro surto observou-se durante uma inspeção preliminar do rebanho que 15 dos 70 animais apresentavam alterações oculares, os animais foram submetidos ao exame físico geral e ao exame oftálmico. Lacrimejamento excessivo, blefarite, fotofobia, opacidade de córnea, hifema, neovascularização corneana, úlceras de córnea e gloquídeos aderidos à conjuntiva bulbar e córnea foram os achados clínicos identificados. A planta estava presente em diversas áreas e em grande quantidade nas áreas de pastejo, onde os animais eram vistos ingerindo seus frutos. No segundo surto, dois ovinos de um total de 100 animais, foram identificados com lesões orais associadas ao pastejo em áreas da planta. Um deles foi encaminhado ao Hospital Veterinário. No exame físico, o animal apresentou apatia, anorexia, escore corporal 1,5, pelos opacos, eriçados e no pelame era possível identificar gloquídeos. Na cavidade oral observou-se halitose, sialorreia intensa, extensas úlceras hemorrágicas e sensibilidade dolorosa à palpação. Devido ao prognóstico desfavorável o animal foi eutanasiado. Na necropsia, placas multifocais a coalescentes, elevadas, firmes e com superfície irregular, ulcerada, por vezes crostosas, com centro amarelo a marrom-claro e bordos eritematosos, estavam presentes nos lábios superiores, inferiores, mucosa oral, língua, palatos duro e mole. T. inamoena causa sérias lesões orais e oftálmicas em pequenos ruminantes no semiárido nordestino e prejuízos econômicos de grandes dimensões, que podem ser agravados pelo comportamento invasor da T. inamoena em áreas com indícios de degradação ambiental.(AU)
