ABSTRACT
Here, we describe an invasive infection due to Trichosporon coremiiforme in an HIV positive patient with neutropenia. The strain was first erroneously identified as Trichosporon asahii by conventional methods, but correctly identified by mass spectrometry using matrix-assisted laser desorption/ionization time-of-flight technology (MALDI-TOF MS) and ribosomal DNA sequencing. The infection was successfully resolved after antifungal treatment with amphotericin B and fluconazole. This case report is a contribution to the study of T. coremiiforme infections and reinforces its relevance as a species capable of causing invasive human infection in immunocompromised patients and also contributes to the study of its susceptibility profile against antifungal drugs.

Trichosporon asahii es un hongo ubicuo que se ha aislado como parte de la microbiota humana. Recientemente, se ha visto una emergencia de este patógeno en infecciones tanto localizadas como sistémicas. En unidades de cuidados intensivos pediátricos para quemados, existen escasos reportes de infecciones del tracto urinario por este microorganismo. Se describen 2 pacientes pediátricos con internación prolongada por quemaduras extensas y múltiples tratamientos antibióticos previos. Ambos presentaron sepsis por infección del tracto urinario asociada a sonda vesical por Trichosporon asahii. En ambos pacientes, se realizó el recambio de la sonda vesical y tratamiento con voriconazol por 10 días, con buena evolución. En los casos presentados, debido a la ausencia de otros aislamientos microbiológicos y a la buena respuesta al tratamiento antifúngico junto con el recambio de la sonda vesical, se asumió al Trichosporon asahii como el probable agente causal de la sepsis.
Trichosporon asahii is a ubiquitous fungus that has been isolated as part of human microbiota. There has been an emergence of this pathogen in recent years, causing superficial and deep seated infections. There are scarce reports of urinary tract infections in pediatric intensive care burn units caused by this agent. We describe the cases of 2 pediatric patients with prolonged hospitalization due to severe burns that had received several antibiotic courses for previous infections. Both presented sepsis secondary to catheter related urinary tract infection by Trichosporon asahii. Both patients underwent urinary catheter replacement and were treated effectively with voriconazole for 10 days. In the cases presented, sepsis was assumed to be due to Trichosporon asahii since no other microorganism was identified and the patients showed favorable outcome with the prescribed treatment with voriconazole and replacement of the urinary catheter.
