Abstract

We have previously reported that itraconazole (ITCZ) at a dose of 200 mg/day is more effective than ITCZ at a dose of 100 mg/day and is safe for prophylaxis of mycosis. In this prospective study, 37 patients with hematological malignancies were administered 200 mg/day of ITCZ for prophylaxis of mycosis during neutropenia. Although none of the patients developed mycosis, 31 patients (83.8%) of the ITCZ administered patients developed neutropenia (neutrophil < 1000/microL), and 12 patients of them showed the possibility of fugitive fungal infection. The prolonged neutropenia and low neutrophil level were observed in the patients with malignant lymphoma at stage III-IV, which suggested the necessity of prophylactic antifungal drugs. Four patients showed the adverse events which might be caused by drug interactions between ITCZ and vinca alkaloid. However adequately modified administration of ITCZ prevented these effect. There were no other obvious side effects which were supposed to be caused by prophylactic ITCZ administration. Twenty-eight patients were measured plasma concentration of ITCZ about 10 days after the beginning of administration and mean trough ITCZ level was expected to be above the effective level (250 ng/ml).
