Abstract
INTRODUCTION: Cases of invasive Trichosporon infections have increasingly emerged; it is now the second leading cause of yeast bloodstream infections after Candida spp., particularly in the immunosuppressed population, where it often causes breakthrough fungemia with high mortality. METHODS: We present a case report of a breakthrough Trichosporon asahii infection in a patient with acute myeloid leukemia and review all of the cases of breakthrough Trichosporon spp. infections published in the literature to date. RESULTS: We extracted 68 cases of breakthrough Trichosporon spp. infections, wherein 95.5% patients had hematological malignancy, 61.8% of them occurred in the presence of echinocandins, 22% of triazoles, 13.2% of amphotericin and 3% of other combinations of antifungals. The most prevalent manifestation was fungemia (94%); 82.8% of these were associated with the presence of a central venous catheter. The overall mortality was 68.7%; the patients who survived recovered from the neutropenic event. CONCLUSIONS: Invasive trichosporonosis is an acute fatal condition that occurs in immunosuppressed patients, usually under antifungal selective pressure. Typically, neutropenia and its underlying diseases are associated with adverse outcomes.
