Poor prognosis of Candida tropicalis among non-albicans candidemia: a retrospective multicenter cohort study, Korea

To evaluate clinical features and prognostic factors of non-albicans candidemia, we conducted a retrospective multicenter cohort study at 7 university hospitals in Korea from January 2010 to February 2016. A total of 721 patients with non-albicans candidemia were included in the analysis. C. tropicalis was most commonly identified (36.5%), followed by C. glabrata (27.2%), C. parapsilosis (25.7%), and C. krusei (2.4%). Clinical presentation of C. tropicalis candidemia was most severe with highest median C-reactive protein level (10.1 mg/dL) and Acute Physiology and Chronic Health Evaluation II score (14, both P ≪ 0.05). C. tropicalis showed the highest 14- and 30-day mortality (28.9% and 44.1%). In multivariate analysis, C. tropicalis infection was significantly related with 14- (P = 0.005) and 30-day mortality (P = 0.033). In conclusion, C. tropicalis infection presented most severely and showed worst clinical outcome among non-albicans candidemia.
