  • Title: Itraconazole in neutropenic patients.
    Author: van't Wout JW.
    Journal: Chemotherapy; 1992; 38 Suppl 1():23-6. PubMed ID: 1319311.
    Abstract:
    Treatment of fungal infections in neutropenic patients continues to be a major problem for the clinician. Treatment of such infections with amphotericin B is difficult, because of its many side-effects. In a neutropenic mouse model, itraconazole appeared to be as effective as amphotericin B against Candida albicans, and was more effective than amphotericin B in treating an Aspergillus infection in a patient with chronic granulomatous disease. In a randomized, comparative trial of itraconazole and amphotericin B as treatment for Candida and Aspergillus infections, 32 neutropenic patients were evaluated. Patients received either oral itraconazole, 200 mg twice daily, intravenous amphotericin B, 0.6 mg/kg/day, or in some cases of Candida infection intravenous amphotericin B, 0.3 mg/kg/day, plus flucytosine, 150 mg/kg/day. The causative organism of fungal infection was Candida spp. in 16 patients and Aspergillus spp. in 13 patients; 27 patients had pneumonia. The median duration of treatment was 13 days with amphotericin B and 20 days with itraconazole. Nine of 16 patients responded to amphotericin B, and 10 of 16 patients responded to itraconazole. Of the patients with Aspergillus infection, 6/8 treated with itraconazole and 2/5 treated with amphotericin B responded. Three patients with Aspergillus infection died in the amphotericin B arm and none in the itraconazole arm; 2 patients treated with itraconazole died from candidal infections. Absorption of itraconazole was unreliable in these seriously ill patients with disturbed gastrointestinal function. These results suggest that itraconazole could be an effective drug against systemic fungal infections in neutropenic patients. One retrospective study also suggest that itraconazole is superior to ketoconazole in prophylaxis for Aspergillus infections. Further studies are needed.
