A Cluster of Neonatal Infections Caused by Candida auris at a Large Referral Center in Colombia.

BACKGROUND: Globally, Candida auris is an emerging pathogen that poses an essential threat in healthcare settings presenting as outbreaks requiring significant allocation of infection control interventions to curb transmission. This fungal pathogen was initially identified in 2009 in Japan, but it has spread to all continents. Candida auris poses significant diagnostic and treatment challenges. Conventional microbiology laboratories often misidentify this pathogen as Candida haemulonii or as other Candida spp., Rhodoturola glutinis, and even with some bacterial pathogens, including Neisseria meningitidis serogroup A. Furthermore, C. auris displays distinct mechanisms of antifungal resistance to azoles and amphotericin B formulations. Most of the case series and outbreak reports have included invasive infections in adult populations. METHODS: Herein, we present a cluster of neonatal infections caused by Candida auris at a large referral center in Colombia. RESULTS: We report a case series of 8 neonates and infant patients who were seen at a large referral center in Colombia and who develop invasive infections caused by C. haemulonii and C. auris. DISCUSSION: Our report highlights the diagnostic challenges in identifying this fungal pathogen correctly, its clinical spectrum of disease, recommendations for empiric antifungal therapy, and it is not always associated with a high case fatality rate.

Infección por Kodamaea ohmeri en un recién nacido con una masa mediastinal / Kodamaea ohmeri infection in a newborn with a mediastinal mass

Las infecciones por hongos son una causa de morbilidad y mortalidad, lo que lleva a un incremento de la estancia hospitalaria y a un aumento de los costos en salud, en el período neonatal. Durante este período, los prematuros son los más afectados. Las especies Candida son la causa principal de infección fúngica. La mayoría son causadas por C. albicans, C. parapsilosis, C. glabrata y C. tropicalis, aunque otras especies han sido reportadas. Una de ellas, como un patógeno emergente, es K. ohmeri. Este organismo ha sido reportado como patógeno en el período neonatal, principalmente en prematuros. Los factores de riesgo asociados a infección fúngica son accesos venosos centrales, inmunosupresión, larga estancia hospitalaria, intubación endotraqueal y uso de antibióticos. Presentamos a un neonato con una masa mediastinal, quien requirió múltiples intervenciones, como pericardiocentesis, catéter central, ventilación mecánica y antibióticos. Durante su evolución, presentó infección por K. ohmeri. Fue tratado con anfotericina B, con evolución clínica satisfactoria.

Invasive fungal infections are a considerable cause of morbidity, mortality, increased hospital stay durations, and high health care costs, during neonatal period. In this period, the premature infants are the most affected. Candida species are the leading cause of invasive fungal infections. The majority of neonatal Candida infections are caused by C. albicans, C. parapsilosis, C. glabrata and C. tropicalis, although other fungus species are being reported. One such emerging pathogen is K. ohmeri. This organism has been reported as a pathogen in the neonatal period, principally in premature infants. The risk factors associated with fungal infection are central line, immunosuppression, prolonged hospital stay, endotracheal intubation and exposure to antibiotics. We present a term baby with a mediastinal mass, who required several procedures, as pericardiocentesis, central catheters, mechanical ventilation, antibiotics. During his evolution, he presented infection by K. ohmeri. The baby was treated with amphotericin B, with satisfactory clinical course.
