QUERATITIS POR ACANTHAMOEBA. INFECCIÓN OCULAR EMERGENTE. REPORTE DE CASOS

Since the first cases of keratitis caused by Acanthamoeba spp. were published in 1974,3 the number of cases has been increasing. This pathology is related to the use of contact lenses and refractive surgeries, not exclusively, however; since the protozoan can be contracted from contaminated water so...

description Since the first cases of keratitis caused by Acanthamoeba spp. were published in 1974,3 the number of cases has been increasing. This pathology is related to the use of contact lenses and refractive surgeries, not exclusively, however; since the protozoan can be contracted from contaminated water sources, such as ponds and lagoons.1,2,5,8,10 The growth of free-living amoebas is favored by the increase in water temperature as a result of global warming and the weather becoming more tropical. In this work, 11 cases of keratitis associated with the use of contact lenses and refractive surgeries are reported, as well as the case of a patient who acquired the protozoa at work, when cleaning a water well. For the lab diagnosis, corneal scraping was performed for direct parasitological analysis and sowing in culture medium. All the cultivated samples were positive for Acanthamoeba spp. This nosological entity is characterized by generating a clinical condition presenting strong eye pain and decreased visual acuity. In the ophthalmological examination, it can be confused with herpetic infection. If the infection is not diagnosed and treated in a timely manner, it can lead to perforation of the cornea and vision loss.

RELATÓRIO DOS CASO Maffrand, Roque Pizzi, Rogelio Páez Rearte, Mirtha Tomas, Axel Maffrand, Carola Pizzi, Hugo Luis Keratitis Acanthamoeba Cornea Protozoan Queratitis Acanthamoeba Córnea Protozoos Since the first cases of keratitis caused by Acanthamoeba spp. were published in 1974,3 the number of cases has been increasing. This pathology is related to the use of contact lenses and refractive surgeries, not exclusively, however; since the protozoan can be contracted from contaminated water sources, such as ponds and lagoons.1,2,5,8,10 The growth of free-living amoebas is favored by the increase in water temperature as a result of global warming and the weather becoming more tropical. In this work, 11 cases of keratitis associated with the use of contact lenses and refractive surgeries are reported, as well as the case of a patient who acquired the protozoa at work, when cleaning a water well. For the lab diagnosis, corneal scraping was performed for direct parasitological analysis and sowing in culture medium. All the cultivated samples were positive for Acanthamoeba spp. This nosological entity is characterized by generating a clinical condition presenting strong eye pain and decreased visual acuity. In the ophthalmological examination, it can be confused with herpetic infection. If the infection is not diagnosed and treated in a timely manner, it can lead to perforation of the cornea and vision loss. Desde que se publicaron los primeros casos de queratitis causados por Acanthamoeba spp., en 1974, 3 la cifra fue en aumento. Esta patología está relacionada con el uso de lentes de contacto y las cirugías refractivas, aunque no de manera excluyente, ya que el protozoario puede contraerse de fuentes de agua contaminadas, como lagunas y estanques. 1, 2, 5, 8, 10 El crecimiento de las amebas de vida libre se ve favorecida por el aumento de la temperatura del agua producto del calentamiento global y la tropicalización del clima. En el presente trabajo, se informan 11 casos de queratitis asociados al uso de lentes de contacto y cirugías refractivas y el caso de un paciente que adquirió los protozoos en su tarea laboral limpiando un aljibe. Para el diagnóstico de laboratorio se realizó raspado corneal para llevar a cabo el parasitológico directo y la siembra en medio de cultivo. Todas las muestras cultivadas resultaron positivas para Acanthamoeba spp. Esta entidad nosológica se caracteriza por generar un cuadro clínico caracterizado por fuertes dolores oculares y disminución de la capacidad visual. En el examen oftalmológico, se puede confundir con una infección herpética. Si la infección no se diagnostica y se trata de manera oportuna, puede conducir a la perforación de la córnea y a la pérdida del ojo. A partir da publicação dos primeiros casos de ceratite causada por Acanthamoebaspp, em 1974, 3 o número deles foi aumentando. Esta patologia tem  relação com o uso de lentes de contato e cirurgias refrativas, ainda que de maneira não exclusiva, já que o protozoário pode ser contraído em fontes de água contaminadas, tais como lagos e lagoas1,2,5,8,10. O crescimento de amebas de vida livre é favorecido pelo aumento da temperatura d‘água devido ao aquecimento global e à tropicalização do clima. Neste trabalho, 11 casos de ceratite associados com o uso de lentes de contato e cirurgia refrativa e um deles, o paciente que foi infectado por protozoários em seu trabalho durante a limpeza de uma cisterna. Para o diagnóstico laboratorial, realizou-se raspagem corneana para o teste parasitológico direto e semeadura em meio de cultura. Todas as amostras cultivadas foram positivas para o Acanthamoebaspp. Essa entidade nosológica é caracterizada por gerar um quadro clínico que emerge com uma forte dor ocular e diminuição da acuidade visual. No exame oftalmológico, pode ser confundido com uma infecção herpética. Se a infecção não for oportunamente diagnosticada e tratada, pode levar à perfuração da córnea e à perda do olho.
