Nosocomial candidaemias due to species other than Candida albicans in cancer patients. Aetiology, risk factors, and outcome of 45 episodes within 10 years in a single cancer institution.

Forty-five cases of fungaemia due non-albicans Candida spp. (NAC) in a single National Cancer Institution within 10 years were analysed for aetiology, risk factors and outcome. There had been 12 cases of fungaemia that were due to C. krusei, 14 due to C. parapsilosis, 7 due to C. (T.) glabrata, 6 to C. tropicalis, 2 to C. guillermondii, 2 to C. lusitaniae, 1 to C. stellatoidea, and 1 to C. rugosa. Comparison of 45 NAC fungaemia with 75 episodes of C. albicans fungaemia revealed differences only in two risk factors: previous empiric therapy with amphotericin B (16.0 vs 2.2%, P<0.01) appeared more frequently in cases of C. albicans fungaemia, and prior prophylaxis with fluconazole (8.9 vs 0%, P<0.02) was conversely more frequently observed with NAC. The incidence of other risk factors, such as underlying disease, chemotherapy, antibiotic prophylaxis or therapy, treatment with corticosteroids, catheter insertion, mucositis, cytotoxic chemotherapy, and neutropenia, was similar in both groups. There was no difference either in attributable or in overall mortality between NAC and C. albicans fungaemia in our cancer patients.
