RESUMO
Resumen Candida auris es una levadura multi-resistente emergente con rápida diseminación mundial. Desde el primer reporte el 2009, varios aislados a través de los cinco continentes han sido identificados como agentes de infecciones asociadas a la atención en salud. Brotes independientes y simultáneos por C. auris se han vuelto prioridad para la comunidad hospitalaria y científica. Además, los errores en identificación y los perfiles de multi-resistencia, raramente observados para otras especies de Candida, resultan en una difícil erradicación y fallas terapéuticas frecuentes en infecciones por C. auris. Presentamos el primer aislamiento de una cepa de C. auris en un hospital en Santiago, en un paciente proveniente de la India, que fue admitido para tratamiento de su pie diabético. La cepa fue recuperada de un cultivo de tejido e identificada por VITEK® 2 Compact. La identificación de C. auris fue confirmada por MALDI-TOF MS y secuenciación. El aislado fue resistente a fluconazol y susceptible a anfotericina y caspofungina, según puntos de corte recomendados por el CDC. La emergencia de C. auris es alarmante debido a que el modo de transmisión dentro del ambiente hospitalario no es claro y probablemente es multifactorial.
Candida auris is an emerging multi-drug-resistant fungus that is rapidly spreading worldwide. Since the first reports in 2009, many isolates across five continents have been identified as agents of hospital-associated infections. Independent and simultaneous outbreaks of C. auris are becoming a major concern for healthcare and scientific community. Moreover, laboratory misidentification and multi-drug-resistant profiles, rarely observed for other non-albicans Candida species, result in difficult eradication and frequent therapeutic failures of C. auris infections. In this article we present the first case of isolation of a strain of C. auris at a hospital in Santiago, in a patient coming from India, who was admitted for treatment of diabetic foot complications. The strain was recovered from a tissue culture and identified by VITEK® 2 Compact. The accurate identification of C. auris was confirmed by means of MALDI-TOF MS and DNA sequence analysis. The isolate was resistant to fluconazole, retaining only susceptibility to amphotericin and caspofungin with MIC breakpoints recommended by CDC. The emergence of C. auris is alarming because the mode of transmission within the healthcare environment is not clear and is likely to be multifactorial.
