RESUMO

A retrospective analysis of fungal infections was carried out in a health-care burn center between 2011 and 2014 using the patients' medical records (n = 36). Patients ranged from 18 to 87 years of age, with 23 (63.9%) being women. The most prevalent widespread total body surface area affected (TBSA) was 30-50% (p = 0.03), and 71-100% in younger patients, mainly associated with femicide. Fourth degree burns were revealed in 69.4% of the patients while in 50%, inhalation injuries were observed to represent a higher mortality rate (p = 0.04). The Candida score was 3 in 77.7% of cases respectively. Central venous catheter and mechanical ventilation were used. All patients received antibiotic treatment and 91.7% antifungal treatment. Surgical excision of the burn was performed in 33 (91.7%) patients, and skin autografting in 29 (80.6%). The median of the fungal infection developed was 21.4 days after admission to the ICU. The specimens analyzed involved 52 yeast samples isolated from different cultures: urine (42.3%), blood (26.9%), skin biopsy (9.6%), catheter tip (15.4%) and tracheal aspirate (5.8%). The use of microbiological culture and molecular methods allowed for the identification of Candida albicans (53.8%), C. tropicalis (23.1%), C. parapsilosis sensu stricto (13.5%), C. krusei (5.8%), C. glabrata (1.9%) and C. dubliniensis (1.9%). Fungal infections observed in skin burns lead to severe complications in at-risk patients.


Se realizó un estudio retrospectivo de las infecciones fúngicas atendidas en un centro de quemados de alta complejidad situado en Buenos Aires, entre 2011 y 2014, mediante el análisis de las historias clínicas (n = 36). Las edades de los pacientes estuvieron entre 18 y 87 años, y 23 (63.9%) fueron mujeres. La extensión de la superficie corporal afectada más prevalente varió entre 30 y 50% (p = 0.03), y entre 71% y 100% en pacientes de menor edad, relacionándose con intentos de femicidio. En el 69.4% la profundidad de la quemadura fue grado 4, y en el 50% de los casos se observaron lesiones por inhalación, con una alta mortalidad (p = 0.04). El Candida score resultó de 3 en el 77.7% de los casos. Se usaron vías centrales y ventilación mecánica. Todos los pacientes recibieron tratamiento antibiótico y en 33 (91.7%) antifúngicos. La escisión quirúrgica de la quemadura se practicó en 33 (91.7%) y los autoinjertos de piel en 29 (80.6%). La infección fúngica se desarrolló en una media de 21.4 días del ingreso en UCI. Se estudiaron 52 muestras de levaduras que se aislaron de urocultivo (42.3%), hemocultivo (26.9%), biopsia cutánea (9.6%), punta de catéter (15.4%) y aspirado traqueal (5.8%). Por cultivo microbiológico y métodos moleculares se identificaron a Candida albicans (53.8%), C. tropicalis (23.1%), C. parapsilosis sensu stricto (13.5%), C. krusei (5.8%), C. glabrata (1.9%) y C. dubliniensis (1.9%). Las infecciones fúngicas representan severas complicaciones en quemados con factores de riesgo.

RESUMO

Abstract The yeast Saccharomyces cerevisiae var. boulardii is a biotherapeutic agent used for the prevention and treatment of several gastrointestinal diseases. We report a case of fungemia in a patient suffering from Clostridium difficile-associated diarrhea and treated with metronidazole and a probiotic containing S. cerevisiae var. boulardii. The yeasts isolated from the blood culture and capsules were identified by MALDI-TOF MS and API ID 32 C as S. cerevisiae, and showed the same appearance and color on CHROMAgar Candida. Treatment with fluconazole 400mg/day was initiated and the probiotic was stopped. The patient was discharged from hospital in good condition and was referred to a rehabilitation center. We suggest that the potential benefit of S. cerevisiae var. boulardii should be accurately evaluated, especially in elderly patients. Moreover, all physicians should be trained in the use of probiotic agents and enquire whether the use probiotics was included in the patients'medical histories. © 2019 Asociación Argentina de Microbiología.

Resumen Saccharomyces cerevisiae var. boulardii es un agente bioterapéutico usado en la prevención y el tratamiento de varias enfermedades gastrointestinales. Informamos de un caso de fungemia en una paciente con diarrea asociada a Clostridium difficile, y tratada con metron-idazol y un probiótico que contenía S. cerevisiae var. boulardii. Las levaduras aisladas a partir del hemocultivo y del contenido de las cápsulas tomadas por la paciente se identificaron como S. cerevisiae mediante MALDI-TOF MS y API® ID 32C, las colonias mostraron el mismo color y aspecto en el medio CHROMAgar™ Candida. Se instauró un tratamiento con fluconazol 400mg/día y se suspendió el probiótico. La paciente fue dada de alta del hospital en buenas condiciones, y remitida a un centro de rehabilitación. Sugerimos que el beneficio potencial del uso de S. cerevisiae var. boulardii debe ser evaluado en cada paciente, especialmente en personas añosas. El uso de probióticos debería incluirse en los interrogatorios orientados al diagnóstico y formar parte de la historia clínica. © 2019 Asociación Argentina de Microbiología.

RESUMO

Saksenaea erythrospora is a species of the order Mucorales recently described and reported as a cause of human mucormycosis. We report a case of S. erythrospora in a man involved in a serious sailing accident causing deep skin and soft tissue contamination with soil and water. Direct microscopic examination of the clinical sample with Giemsa stains showed hyaline and non-septate hyphae belonging to the order Mucorales. Fungal identification was performed by culture of biopsy material on SDA, and identification of species by floating an agar block containing the fungus in a nutritionally deficient medium consisting of sterile distilled water supplemented with 0.05 % yeast extract; and by sequencing the ITS region of the rDNA. This is the first report to our knowledge of infection with S. erythrospora in Argentina, confirming the presence of this fungus in this country.
