Antifungal prophylaxis with itraconazole in neutropenic patients with acute leukaemia.
The efficacy of antifungal prophylaxis with itraconazole capsules and its serum concentrations were evaluated in patients intensively treated for acute leukaemia. A consecutive group of patients without systemic antifungal prophylaxis (January 1993 to August 1994, period 1) was compared with another consecutive group of patients (period 2) who received itraconazole capsules (September 1994 to April 1995 400 mg/day, from May 1995 onwards 600 mg/day). All patients admitted with acute leukaemia and standard or high-dose chemotherapy were included into the study. Clinical endpoint was mortality from proven fungal infection. Seventy-six patients and 148 courses of cytotoxic chemotherapy were analysed in the control group as well as 47 patients and 112 treatment courses in the intervention group. Antifungal prophylaxis led to a significant decrease of mortality from invasive fungal infections (8.8%-0.9%, P = 0.005). The median trough concentration of itraconazole of all measurements was 520 ng/ml (range 230-793) in patients who received 400 mg/day and 760 ng/ml (370-1200) in patients receiving a dosage of 600 mg/day (P = 0.002). These findings suggest that itraconazole is an effective drug for antifungal prophylaxis but also that a considerable number of patients do not reach the desired trough levels (>500 ng/ml) with itraconazole capsules.
