During the period 2001-2010, a total of 154 episodes of candidaemia were noted in 111 of 2574 patients with haematological malignancies at the National Taiwan University Hospital (Taipei, Taiwan). Patients with acute lymphoblastic leukaemia had a significantly higher rate of candidaemia than patients with other haematological malignancies (odds ratio = 2.69; P < 0.001). Candida tropicalis was the most common Candida species (n = 51; 46%), followed by Candida albicans (n = 35; 32%), Candida parapsilosis (n = 13; 12%), Candida glabrata (n = 8; 7%) and Candida krusei (n = 4; 4%). Persistent candidaemia was initially identified in 21 patients (18.9%) and was frequently associated with central venous catheter-related infection (52% vs. 24%; P = 0.017). Multivariate analysis revealed that shock (P < 0.001), allogeneic transplantation (P = 0.033) and elderly age (>= 60 years) (P = 0.041) were independent prognostic factors of 30-day overall survival in patients with haematological malignancy and candidaemia. Minimum inhibitory concentrations (MICs) of a total of 103 non-duplicate blood isolates of Candida spp., including 82 isolates from 82 patients without persistent candidaemia and 21 isolates causing first episodes among 21 patients with persistent candidaemia, to nine antifungal agents were determined using the broth microdilution method. Among the 103 Candida isolates, 53 (51.5%), 94 (91.3%) and 102 (99.0%) were susceptible to itraconazole, fluconazole and voriconazole, respectively. All Candida isolates were susceptible to caspofungin, and 2 (15%) of the 13 C. parapsilosis isolates were not susceptible to micafungin or anidulafungin. The MIC90 (MIC for 90% of the organisms) of posaconazole was 0.03 mg/L for C. albicans, 0.5 mg/L for C. tropicalis, 0.12 mg/L for C. parapsilosis and 2 mg/L for C. glabrata. (C) 2012 Elsevier B.
