OBJECTIVES: To investigate the clinical characteristics and treatment outcomes of adult patients with Candida parapsilosis sensu lato candidaemia.
METHODS: We evaluated data in the mycology database of the National Taiwan University Hospital and on patients diagnosed with candidaemia due to C. parapsilosis sensu lato species from 2000 to 2012. Isolates were identified to the species level by conventional identification methods, MALDI-TOF and gene sequencing analysis.
RESULTS: A total of 323 adult patients with candidaemia caused by C. parapsilosis sensu lato species were evaluated, including 256 (79.3%) patients with C. parapsilosis sensu stricto, 34 (10.5%) with Candida orthopsilosis and 33 (10.2%) with Candida metapsilosis. There were 222 men and 101 women and the median age was 60 years (range 18-103 years). Among them, 178 (55%) had an underlying diagnosis of cancer. The overall 30 day mortality rate was 25% (n = 80). Multivariate analysis revealed that shock (P < 0.001), antifungal therapy (P = 0.002), central catheter removal (P = 0.02) and abdominal surgery (P = 0.043) were independent prognostic factors for patients with candidaemia due to C. parapsilosis sensu lato species. There were no significant differences in 30 day mortality rate among patients with candidaemia caused by the three different species (P = 0.770). All isolates of C. metapsilosis, C. orthopsilosis and C. parapsilosis sensu stricto were susceptible to voriconazole. WT isolates were susceptible to itraconazole, posaconazole and amphotericin B.
CONCLUSIONS: There were no significant differences in 30 day mortality among patients with candidaemia caused by C. parapsilosis sensu stricto, C. metapsilosis or C. orthopsilosis. The currently used antifungal agents exhibited good in vitro activities against C. parapsilosis sensu lato species isolates.
