ABSTRACT

BACKGROUND:

Exophiala dermatitidis is a dematiaceous fungus known to cause superficial, subcutaneous, cutaneous and deep seated infections, and rarely central line associated bloodstream infection (CLABSI). A case of CLABSI due to E. dermatitidis in an infant is described. CASE REPORT Clinical and laboratory data were extracted from patient's chart and laboratory records. The isolate was identified as E. dermatitidis by phenotypic characterization and sequencing of the ITS and LSU regions of the ribosomal DNA. Medline search was done to review all cases of CLABSI due to E. dermatitidis. Among the azoles tested, posaconazole (0.06mg/l), voriconazole (0.03mg/l) and itraconazole (0.03mg/l) showed very low MICs when compared to fluconazole (4mg/l).

CONCLUSIONS:

As we did not found in the literature any case of CLABSI due to E. dermatitidis in an infant, we report the first one. Sequencing is a mandatory method for accurately identifying this species. Prompt removal of the central line, followed by a treatment with amphotericin B or an azole, seems to be the most effective treatment
RESUMEN
ANTECEDENTES Exophiala dermatitidis es un hongo dematiáceo conocido por causar infecciones superficiales, subcutáneas, cutáneas y profundas, y rara vez infección del torrente sanguíneo asociada a catéter central (central line associated bloodstream infection [CLABSI]). Se describe un caso de CLABSI debido a E. dermatitidis en un bebé. CASO CLÍNICO Los datos del paciente se extrajeron de la historia clínica y de los registros de laboratorio. El aislamiento se identificó como E. dermatitidis mediante caracterización fenotípica y la secuenciación de las regiones ITS y LSU del ADN ribosómico. Se realizó una búsqueda en Medline para revisar todos los casos de CLABSI debidos a E. dermatitidis. Entre los azoles evaluados, el posaconazol (0,06mg/l), el voriconazol (0,03mg/l) y el itraconazol (0,03mg/l) mostraron valores de MIC muy bajos en comparación con el fluconazol (4mg/l).

CONCLUSIONES:

Tras la revisión de todo lo publicado en la literatura, presentamos el primer caso de CLABSI debido a E. dermatitidis en un lactante. La secuenciación es necesaria para identificar con precisión esta especie. La retirada inmediata del catéter venoso central seguida de un tratamiento con anfotericina B o un azol es el tratamiento más efectivo
