OBJECTIVE: Invasive Trichosporon infection has been increasingly recognized in patients with hematologic malignancies. Our study aims to clarify the clinical characteristics of this disease and factors influencing patient prognosis. PATIENTS AND METHODS: We retrospectively analyzed 33 cases of Trichosporon fungemia (TF) in patients with hematologic malignancies treated at our collaborating five hospitals in Japan between 1992 and 2007. RESULTS: The majority of these patients had acute leukemia (82%), neutropenia (85%), and a history of intensive chemotherapy (91%). TF occurred as a breakthrough infection during antifungal therapy in 30 patients (91%), 18 of whom were receiving micafungin. The surveillance cultures of most patients were negative for Trichosporon. Only a few patients exhibited elevated levels of 1,3-beta-d-glucan before positive blood culture. Twenty-five patients (76%) died of this infection. The resolution of infection was associated with neutrophil recovery (P = 0.0001), absence of hyperglycemia (P = 0.023), and azole inclusive therapy (P = 0.031). Survival was significantly longer in patients receiving antifungal therapies containing azole than in those who did not receive azole (P = 0.0034). CONCLUSIONS: At present, the diagnosis of invasive trichosporonosis depends on blood culture studies, and the mortality of this disease is high; however, azole therapy and control of blood glucose level, together with hematopoietic recovery could help in improving the clinical outcome. When we use antifungals lacking anti-Trichosporon activity, sufficient care should be taken to prevent the development of breakthrough trichosporonosis.
