Safety and efficacy of itraconazole in prevention of fungal infections in neutropenic patients.

In a non-randomized study the efficacy of itraconazole in preventing fungal infections in neutropenic patients was investigated. Forty-seven patients with acute leukemia or advanced lymphoblastic lymphoma were enrolled. Ninety-two episodes of severe neutropenia after chemotherapy were observed. Mean duration of neutropenia was 24 days. Norfloxacin was administered as prophylaxis against gram-negative infections and itraconazole 200 mg b.i.d. as antifungal prophylaxis. Surveillance cultures of throat, urine, feces and vagina or prepuce were performed regularly. Four patients died, two patients due to heart failure, two patients due to staphylococcal pneumonia. Only in one case Candida albicans was cultured from bronchoalveolar lavage fluid. No systemic mycosis or Aspergillus fumigatus pneumonia was documented. In a similar group of patients treated in the preceding 18 months nystatin was used as antifungal prophylaxis. In this group of patients six cases of Aspergillus fumigatus pneumonia, two cases of Candida albicans fungemia and one case of Candida glabrata pneumonia occurred of which six patients died. Itraconazole seems to be effective in preventing fungal infections in neutropenic patients and is well tolerated.
