Fungal keratitis management in a referral cornea center in Brazil / Manejo de ceratites fúngicas em centro de referência no Brasil

Abstract Purpose: To report etiological diagnosis, predisposing risk factors, therapeutic strategies and visual outcome of patients treated at the Department of Ophthalmology of Federal University of São Paulo. Methods: This is a retrospective, descriptive, and observational study from medical and laboratory records of the Department of Ophthalmology of Federal University of São Paulo, including all patients with culture proven fungal keratitis in 5 years, from October 2012 through October 2017. Results: There were 2260 fungi microbiologic test requests. Of these, 140 samples had positive cultures for fungi and sixty-six patients were followed at our clinic. Forty-five patients (68.2%) were men, and the mean age was 48.06 (±17.39) years. Fusarium spp. was the most frequently isolated fungus (32 cases; 48.5%), followed by Candida parapsilosis (12 cases; 18.2%). Thirty-four patients (51.5%) underwent intracameral injection of amphotericin B (5 µg per 0.1 ml). In 11 patients (32.3%), infection was eradicated after intracameral amphotericin B associated to topical antifungal treatment and, in 23 patients (67.7%), therapeutic keratoplasty was needed. No complication related to intracameral amphotericin B injection was observed in this series. Forty-three patients (65.1%) ended up with therapeutic keratoplasty. Three patients (4.5%) evolved to evisceration or enucleation. At the last follow-up visit, 53 patients (80.3%) had visual acuity worse than 20/200. Conclusion: Despite current antifungals drugs and distinct administration strategies, fungal keratitis remains challenging. Delayed antifungal therapy may explain poor clinical outcomes. Intracameral amphotericin B associated to topical antfungal treatment seems to be a safe and helpful alternative for non-responsive fungal keratitis. But it is important to formulate other treatment strategies, hence to improve patients' outcomes, since most patients ended-up with significant visual impairment even after current treatment.

Resumo Objetivo: Descrever diagnósticos etiológicos, fatores de risco, estratégias terapêuticas e resultados visuais de pacientes com ceratite fúngica tratados no Departamento de Oftalmologia da Universidade Federal de São Paulo. Métodos: Trata-se de um estudo retrospectivo, descritivo e observacional, a partir da análise de prontuários médicos e laboratoriais do Departamento de Oftalmologia da Universidade Federal de São Paulo, incluindo todos os pacientes com ceratite fúngica comprovada por cultura no período de outubro de 2012 a outubro de 2017. Resultados: Foram realizadas 2260 solicitações de testes microbiológicos. Destas, 140 amostras apresentaram culturas positivas para fungos, e 66 pacientes foram acompanhados em nosso serviço. Quarenta e cinco pacientes (68,2%) eram do sexo masculino, e a média de idade foi de 48,06 (± 17,39) anos. Fusarium spp. foi o fungo mais freqüentemente isolado (32 casos; 48,5%), seguido por Candida parapsilosis (12 casos; 18,2%). Trinta e quatro pacientes (51,5%) foram submetidos à injeção intracameral de anfotericina B (5 µg por 0,1 ml). Destes, 11 pacientes (32,3%) tiveram a infecção erradicada. Nos outros 23 pacientes (67,7%), o transplante terapêutico foi necessário. Nenhuma complicação relacionada à injeção intracameral de anfotericina B foi observada neste estudo. No total, 43 pacientes (65,1%) evoluíram para transplante terapêutico, e 3 pacientes (4,5%) foram submetidos à evisceração ou enucleação. Cinquenta e três pacientes (80,3%) apresentaram acuidade visual final pior que 20/200. Conclusões: Apesar dos diversos medicamentos antifúngicos atuais e vias de administração, o tratamento das ceratites fúngicas permanece desafiador. O atraso no início do tratamento adequado pode justificar o desfecho clínico desfavorável de grande parte dos pacientes. A injeção intracameral de anfotericina B mostrou-se uma alternativa terapêutica segura para ceratites fúngicas refratárias. Mas outras estratégias de tratamento devem ser formuladas, visando melhorar os resultados visuais dos pacientes.

Significativo aumento de onicomicosis por hongos filamentosos no dermatofitos en red de salud privada en Santiago de Chile entre los períodos 2008-2009 y 2016-2017 / Significant increase in onychomycosis due to Filamentous Fungi Non Dermatophytes in Network of Private Health in Santiago de Chile among the periods 2008-2009 and 2016-2017

INTRODUCCION: La onicomicosis corresponde a una patología prevalente causada por hongos dermatofitos, levaduras y en menor proporción, hongos filamentosos no dermatofitos (HFND). Se ha reportado un aumento a nivel mundial en la incidencia de onicomicosis por HFND1 , sin embargo, en Chile no hay registros de ello. OBJETIVO: Comparar la epidemiología local de onicomicosis por HFND en una red privada de Santiago de Chile entre dos períodos de tiempo. Material y métodos: Se realizó un estudio transversal de análisis de los registros de laboratorio de la Red de Salud UC-Christus entre los períodos 2008- 2009 y 2016-2017. RESULTADOS: Se obtuvieron un total de 9.579 muestras en ambos períodos, 4.985 entre 2008-2009 y 4.594 entre 2016-2017, con 3.442 (36%) cultivos positivos para hongos, 1.831 (36,7%) en el primer período y 1.611 (35%) en el segundo. Del total 40 muestras (1,2%) fueron de HFND, destacando que la prevalencia aumentó significativamente entre ambos períodos: 8 (0,4%) y 32 (2,0%) cultivos, respectivamente (p<0,0001). Del total, las especies de HFND más prevalentes fueron: 23 Fusarium sp (57,5%), 8 Scopulariopsis sp (20%) y 7 Acremonium sp (17,5%). En pacientes con cultivo positivo para HFND, se buscaron asociaciones probables en los antecedentes a través de la ficha clínica, sin encontrar resultados significativos. CONCLUCION: Los HFND son la tercera causa de onicomicosis y su prevalencia fue 1,2%. Las especies más frecuentes fueron Fusarium sp, Scopulariopsis sp, Acremonium sp. La prevalencia de HFND aumentó significativamente en un período de 6 años.

INTRODUCTION: Onychomycosis is a frequent nail disease caused mainly by dermatophytes, in less proportion yeast and last non-dermatophyte molds (NDM). NDM onychomycosis is an increasing problem worldwide, though in Chile there is no epidemiological registry about it. OBJETIVE: The aim of the study was to determine the local epidemiology of NDM onychomycosis. MATERIAL Y METHODS: We did a transversal cohort study in the Red de Salud UC-Christus between 2008-2009 and 2016-2017. RESULTS: Of the 9,579 clinically suspected cases of onychomycosis, 4,985 in 2008-2009 and 4,594 in 2016-2017, 3,448 (36%) cultures were positive in total, 1,831 (36.7%) in the first period and 1,611 (35%) in the second. Only 40 cultures (1.2%) were NDM in total, but the prevalence significantly increased between both periods with 8 (0.45%) and 32 (2.0%) cultures, respectively (p y (p<0.0001). Among the total of NDM, the most prevalent species were: 23 Fusarium sp (57.5%), 8 Scopulariopsis sp (20%) and 7 Acremonium sp (17.5%). We searched for possible associations of patients with NDM onychomycosis and morbid history, but found no significant result. COMCLUSION: NDM are the third cause of onychomycosis and its prevalence of 1.2% was predominantly from toe nails. The most frequent species were Fusarium sp, Scopulariopsis sp. and Acremonium sp. The prevalence of NDM increased significantly in a period of 6 years.

Correlation between pathogenic species and clinical findings, disease severity, and visual outcome in patients with fungal keratitis / Correlação entre espécies patogênicas e achados clínicos, gravidade da doença e desfecho visual em pacientes com ceratite fúngica

ABSTRACT Purpose: To determine whether a correlation exists between pathogenic species and clinical findings, disease severity, and visual outcome in patients with keratitis and fungal growth in microbiological culture. Methods: A retrospective study of patients with fungal growth in the microbiological culture of corneal scrapings. Patients were treated at an ophthalmologic reference center in Southeastern Brazil from January 1992 to October 2015. Results: Medical records of 181 patients (131 males and 50 females) with a mean age of 47 ± 18 years were analyzed. The three most common etiologies were Fusarium sp. (38.7%), Aspergillus sp. (15%), and Candida sp. (13.2%). Among these, Fusarium sp. was the most frequent in patients aged £50 years (p=0.002) and in those with a recent history of a foreign body and/or ocular trauma (p=0.01). Candida sp. was the most frequent etiology in patients aged >50 years (p=0.002), in those with postoperative ocular surgery (p=0.002); in those with a previous ocular pathology (p=0.0007); and in immunodepressed patients (p=0.0004). Conclusion: Fusarium sp. was predominant in patients aged £50 years and those with a recent history of foreign body and/or ocular trauma, whereas Candida sp. was predominant in older adults, in those with a postoperative ocular surgery, in those with a previous ocular pathology, and in immunodepressed patients.

RESUMO Objetivo: Determinar se existe uma correlação entre espécies patogênicas e achados clínicos, gravidade da doença e resultado visual em pacientes com ceratite e crescimento de fungos em cultura microbiológica. Métodos: Estudo retrospectivo de pacientes com crescimento de fungos na cultura microbiológica de raspado de córnea. Os pacientes foram tratados em um centro de referência oftalmológica no Sudeste do Brasil de janeiro de 1992 a outubro de 2015. Resultados: Foram analisados registros médicos de 181 pacientes (131 homens e 50 mulheres) com idade média de 47 ± 18 anos. As três etiologias mais comuns foram Fusarium sp. (38,7%), Aspergillus sp. (15%) e Candida sp. (13,2%). Entre estas, Fusarium sp. foi a mais frequente em pacientes com idade £50 anos (p=0,002) e naqueles com história recente de corpo estranho e/ou trauma ocular (p=0,01). Candida sp. foi a etiologia mais frequente em pacientes com idade >50 anos (p=0,002), naqueles com cirurgia ocular pós-operatória (p=0,002); naqueles com patologia ocular prévia (p=0,0007); e em pacientes imunodeprimidos (p=0,0004). Conclusão: Fusarium sp. foi predominante em pacientes com idade £50 anos e naqueles com história recente de corpo estranho e/ou trauma ocular; enquanto Candida sp. foi predominante em adultos mais velhos, naqueles com cirurgia ocular pós-operatória, naqueles com patologia ocular prévia e em pacientes imunodeprimidos.

Associação entre resiliência e qualidade de vida relacionada à saúde bucal em idosos / Association between resilience and quality of life related to oral health in the elderly

OBJETIVO: Avaliar a associação entre resiliência e qualidade de vida relacionada à saúde bucal, por meio de uma abordagem hierárquica baseada em um modelo teórico conceitual em uma coorte de idosos do Rio Grande do Sul. MÉTODOS: Foi conduzido um estudo transversal aninhado a um estudo de coorte, em 2008. Foram avaliados 498 idosos de Carlos Barbosa, Rio Grande do Sul. As medidas avaliadas foram sociodemográficas, comportamentos de saúde, qualidade de vida relacionada à saúde bucal, medida pelo Oral Health Impact Profile (OHIP-14), Escala de Resiliência e CPOD. A associação entre o potencial de resiliência e os impactos na percepção de saúde bucal relacionados à qualidade de vida foi verificada por meio de regressão binomial negativa. Razões das médias (RM) são apresentadas com seus intervalos de confiança de 95% (IC95%). RESULTADOS: Maiores médias do OHIP foram encontradas entre mulheres (6,7 ± 6,3; p = 0,011), moradores da zona rural (7,3 ± 6,7; p = 0,004) e solteiros (8,0 ± 6,3; p = 0,032). O modelo final da análise multivariada mostrou que ser morador da zona rural (RM = 1,32; IC95% 1,06 - 1,65) e casado (RM = 1,36; IC95% 1,07 - 1,72) foram variáveis independentemente associadas à qualidade de vida relacionada à saúde bucal. Não houve associação entre resiliência e qualidade de vida relacionada à saúde bucal. CONCLUSÃO: Os resultados sugerem que variáveis sociodemográficas estão associados à qualidade de vida relacionada à saúde bucal. A hipótese de que a resiliência pudesse exercer um papel importante no desfecho não foi confirmada. .

OBJECTIVE: To evaluate the association between psychological resilience and oral health related to quality of life through a hierarchical approach based on a conceptual theoretical model in a cohort of elderly residents in Rio Grande do Sul, Brazil. METHODS: We conducted a cross-sectional study nested in a cohort study in 2008. We evaluated 498 elderly residents in Carlos Barbosa, Rio Grande do Sul. The measures included sociodemographic questionnaire, health behavior, quality of life related to oral health (OHRQOL), measured by the Oral Health Impact Profile (OHIP-14), Resilience Scale, and DMFT. The association between resilience and potential impacts on perceptions of oral health-related quality of life was assessed through negative binomial regression. Mean ratios (MR) are presented with 95% confidence intervals (95%CI). RESULTS: Higher means of OHIP were found in women 6.7 ± 6.3; p = 0.011), in rural dwellers (7.3 ± 6.7; p = 0.004) and singles (8.0 ± 6.3; p = 0.032). The final model of multivariate analysis showed that being a rural dweller (MR = 1.32; 95%CI 1.06 - 1.65) and being married (MR = 1.36; 95%CI 1.07 - 1.72) were independently associated with OHRQOL. There was no association between resilience and OHRQOL. CONCLUSION: The results suggest that factors such as sociodemographic variables are associated with OHRQOL. The hypothesis that resilience might play a role in the outcome has not been confirmed. .

Se presentan las características clínicas, microbiológicas y los resultados del tratamiento de 76 casos de micetomas observados en el período 1989-2004 en el Hospital Muñiz. Cuarenta y nueve fueron varones y 27 mujeres, con una edad promedio de 43,4 años. La mayor parte de los pacientes adquirió la infección en nuestro país, las provincias más afectadas fueron Santiago del Estero con 31 casos y el Chaco con 11; 8 enfermos procedían del exterior, 6 de Bolivia y 2 de Paraguay. El promedio de evolución de la enfermedad fue de 9,2 años. Las localizaciones más comunes fueron las de los miembros inferiores: pies 63, tobillos 3 y rodillas 2. Se comprobó compromiso óseo en 48 casos y adenomegalias en 5. Fueron identificados los siguientes agentes causales: Madurella grisea 29 casos, Actinomadura madurae 26, Scedosporium apiospermum 5, Nocardia brasiliensis 5, Acremoniun spp. 4 (Acremonium falciforme 2, Acremonium kiliense 1 y Acremonium recifei 1), Madurella mycetomatis 3, Fusarium solani 2, Nocardia asteroides y Streptomyces somaliensis 1 caso cada uno. Los tratamientos más frecuentemente utilizados fueron ketoconazol o itraconazol en los micetomas maduromicósicos y la asociación de cotrimoxazol con ciprofloxacina o amicacina en los micetomas actinomicéticos. La amputación del miembro afectado se realizó en 6 casos, 25 pacientes alcanzaron la remisión clínica completa y 34 presentaron mejorías importantes.

This work presents clinical, microbiological and outcome data collected from 76 patients with mycetomas at the Muñiz Hospital from 1989 to 2004. Forty-nine patients were male and 27 female; the mean age was 43.4 years. The majority of the patients acquired the infection in Argentina: the most affected provinces were Santiago del Estero with 31 cases, and Chaco with 11; 8 cases came from other countries (Bolivia 6 and Paraguay 2). The mean evolution of the disease was 9.2 years. The most frequently observed sites were: feet 63 cases, ankles 3, and knees 2. Forty-eight patients had bone lesions and 5, adenomegalies. The following etiological agents were identified: Madurella grisea 29 cases, Actinomadura madurae 26, Scedosporium apiospermum 5, Nocardia brasiliensis 5, Acremonium spp. 4 (Acremonium falciforme 2, Acremonium kiliense 1, Acremonium recifei 1), Madurella mycetomatis 3, Fusarium solani 2, Nocardia asteroides 1 and Streptomyces somaliensis 1. The main drugs used in the treatments were ketoconazole and itraconazole for maduromycotic mycetomas, and cotrimoxazole associated with ciprofloxacin or amikacin for actinomycetic mycetoma. Six patients had to undergo amputation, 25 cases achieved complete clinical remission and 34 showed remarkable improvement.
