Sepsis secundaria a infección urinaria asociada a sonda vesical por Trichosporon asahii en una unidad pediátrica de quemados: reporte de 2 casos / Trichosporon asahii sepsis associated with urinary catheter in a pediatric burn unit: 2 case reports

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.

Fusarium spp infections in a pediatric burn unit: nine years of experience.

INTRODUCTION: Fusarium spp are ubiquitous fungi recognized as opportunistic agents of human infections, and can produce severe infections in burn patients. The literature on Fusarium spp infections in pediatric burn patients is scarce. OBJECTIVES: To describe the clinical and epidemiological features as well as outcome of Fusarium spp infections in pediatric burn patients. PATIENTS AND METHODS: Retrospective, descriptive study of Fusarium spp infections in a specialized intensive care burn unit. RESULTS: In 15 patients Fusarium spp infections were diagnosed. Median age was 48 months. Direct fire injury was observed in ten patients. The median affected burn surface area was 45%. Twelve patients had a full thickness burn. Fourteen patients had a Garces Index ≥3. Fungal infection developed at a median of 11 days after burn injury. Fungi were isolated from burn wound in 14 patients and from the bone in one patient. Amphotericin B was the drug of choice for treatment followed by voriconazole. Median time of treatment completion was 23 days. One patient (7%) died of fungal infection-related causes. CONCLUSION: In our series Fusarium spp was an uncommon pathogen in severely burnt patients. The burn wound was the most common site of infection and mortality was low.

Manejo inicial del paciente quemado pediátrico / Early management of the vurned child

El manejo inicial del paciente quemado es de vital importancia, ya que puede determinar el pronóstico. El objetivo de esta presentación es proponer pautas de manejo para los pediatras clínicos, quienes son habitualmente los primeros en tomar contacto con este tipo de pacientes, a fin de asegurar al niño quemado las máximas posibilidades de éxito
