Epidemiología de los casos de candidemia en un hospital universitario en Colombia, 2008-2014
##plugins.themes.bootstrap3.article.details##
Introducción: Candida spp. es una levadura comensal de la microbiota humana. Por características del hospedero, las infecciones del torrente sanguíneo pueden aparecer y causar una gran morbimortalidad. Métodos: Estudio restrospectivo transversal analítico de los cultivos positivos para Candida spp. entre 2008 y 2014 en un hospital universitario en Bogotá, Colombia. Se evaluaron las características clínicas y microbiológicas presentes previo a la toma de la primera muestra de sangre positiva y se determinaron asociaciones con infecciones por especies no C. albicans (NCA). Resultados: Se incluyeron 123 casos de candidemia. C. albicans fue la especie más aislada (42 %). Sin embargo, las especies NCA como grupo fueron observadas más frecuentemente. Más del 70 % de los casos presentaron manejo en la unidad de cuidado intensivo, con una mediana de estancia de 14 días previo a la primera muestra de sangre positiva. Se detectaron numerosas características médicas; sin embargo, ninguna estuvo asociada con candidemia por especies NCA. Se observó resistencia a por lo menos un antifúngico en el 29 % de los casos, aunque en una muestra reducida de pruebas de sensibilidad. Conclusiones: Nuestros resultados sustentan el viraje mundial hacia la candidemia por especies NCA; pero no encontramos asociaciones clínicas en este grupo. Debe dársele prioridad a la identificación de factores de riesgo y a la optimización de los puntajes de predicción, que permitan identificar pacientes en riesgo que se beneficien de terapia preventiva.
