ABSTRACT

As infecções causadas por Dipodascus capitatus são raras e de difícil tratamento. Aqui se relata um caso em paciente com leucemia mielocítica aguda. O isolamento fúngico ocorreu a partir de hemocultura e a identificação fenotípica baseou-se em métodos micológicos clássicos; a identificação genotípica foi realizada através do sequenciamento da região D1/D2 do 26 rDNA. Os testes de suscetibilidade foram realizados através do Etest® e microdiluição em caldo. A antifungicoterapia foi ineficaz, registrando-se óbito da paciente no 17° dia após o diagnóstico. Os autores comparam o caso com relatos similares e discutem a emergência destas infecções bem como suas dificuldades diagnósticas e terapêuticas.


The infections caused by Dipodascus capitatus are rare, and the treatment is difficult. We reported a case of a patient with acute myeloid leukemia. The fungus was first isolated from hemocultures, and the phenotypic identification was based on mycological methods. The genotyping was carried out by sequencing the region D1/D2 from 26 rDNA. The susceptibility tests were assayed by Etest® and by the microdilution technique. None of the antifungal treatments employed were effective. The patient died on day 17 after the mycological diagnosis. The authors discussed the emergence of such infections as well as the difficulty regarding the diagnosis and treatment.
