[Nosocomial infection due to Trichosporon asahii: clinical revision of 22 cases].
Twenty two cases of nosocomial infection caused by Trichosporon asahii, detected during a period of six years (1999-2005) is described. The patients were predominantly males with an average age of 47.3 years-old. The predominant diseases in the study group were respiratory insufficiency, cancer, diabetes, chronic renal insufficiency, cirrhosis and AIDS. The main predisposing conditions were antibiotic therapy, mechanical ventilation, urethral catheterization, catheter, corticoids, transplant, immunosuppressive therapy, chemotherapy, granulocytopenia, surgical procedures and continuous ambulatory peritoneal dialysis. The most used antifungal drugs were fluconazole and amphotericin B. In some cases several antifungals were administered. Five patients did not receive antifungal treatment, and one patient received granulocyte colony stimulating factor (G-CSF). Nine patients showed clinical improvement, nine died and the progress of four patients is unknown. T. asahii is an emergent pathogen in patients with immunodeficiency and its presence in these type hosts can not be considered colonization, as there is an important risk of invasive infection. So, in susceptible patients to develop trichosporonosis it is advisable to take into consideration this disease especially in intensive clinical care units.
