Epidemiology and risk factors for non-Candida albicans candidemia in non-neutropenic patients at a Chinese teaching hospital.

The purpose of this study was to describe the epidemiology of nosocomial candidemia and identify risk factors involved in infections caused by non-C. albicans Candida species in a Chinese tertiary care center over a 10-year period. A total of 102 cases of nosocomial candidemia in non-neutropenic patients admitted from 1998 through 2007 were included in the study. Candida albicans remained the most common causative agent, accounting for 57.8% of all cases, followed by C. tropicalis (12.8%), C. parapsilosis (10.8%) and C. glabrata (10.8%). Comparison of C. albicans and non-C. albicans candidemia by multivariate logistic regression showed that factors independently associated with non-C. albicans candidemia included head trauma (OR, 5.34; 95% CI, 1.18-24.17; P = 0.029) and bacterial sepsis (OR, 3.58; 95% CI, 1.17-10.98; P = 0.026). Factors independently associated with C. albicans candidemia included tracheal intubation (OR, 0.26; 95% CI, 0.08-0.92; P = 0.037), and increased peripheral WBC count (OR, 0.84; 95% CI, 0.74-0.95; P = 0.006).
