Successful treatment of Trichosporon mucoides infection with lipid complex amphotericin B and 5-fluorocytosine.
ABSTRACT Infections in immunocompromised children can stem from bacteria, fungi, viruses, or protozoa, but most importantly, from the host's endogenous bacterial flora. Disseminated infection caused by Trichosporon species is one of the emerging mycoses in neutropenic patients, particularly when they are treated for haematological malignancy with cytotoxic and immunosuppressive chemotherapy. We report a 15-year-old boy with acute lymphoblastic leukaemia, whose Trichosporon mucoides infection was successfully treated with lipid complex amphotericin B plus 5-fluorocytosine.
Article: Trichosporon mycotoxinivorans, a novel respiratory pathogen in patients with cystic fibrosis.[show abstract] [hide abstract]
ABSTRACT: This report describes the molecular epidemiology, in vitro susceptibility, colonial and microscopic morphologies, and biochemical features of Trichosporon mycotoxinivorans, a newly recognized pathogen that appears to have a propensity for patients with cystic fibrosis. The index patient died with histologically documented Trichosporon pneumonia complicating cystic fibrosis. This is also the first report of disease caused by a Trichosporon species in a nontransplant patient with cystic fibrosis. As T. mycotoxinivorans has not previously been recognized as a respiratory pathogen, the significance of its recovery from sputum samples was not initially appreciated. Genetic analysis of archived clinical samples found three additional cases of T. mycotoxinivorans infection which had previously been identified as other members of the genus. An additional isolate of T. mycotoxinivorans was identified from a clinical sample on initial testing. Three of these four cases were also patients with cystic fibrosis. All isolates had MICs at 48 h of amphotericin B of > or = 1 microg/ml and of echinocandins of > or = 16 microg/ml, but they displayed various susceptibilities to the triazoles. In summary, Trichosporon mycotoxinivorans is a newly recognized human pathogen that is associated with cystic fibrosis.Journal of clinical microbiology 08/2009; 47(10):3091-7. · 4.16 Impact Factor
