Background and purpose: 

Candida guilliermondii is rarely isolated from clinical specimen. C. guilliermondii fungemia is seldom reported in the literature. The aims of this study were to report the clinical features, antifungal susceptibility, and outcomes of patients with C. guilliermondii fungemia. 



From 2003 to 2015, we retrospectively analyzed the clinical and laboratory data of patients with C. guilliermondii fungemia in a tertiary hospital in mid-Taiwan. We performed a multivariable logistic regression analysis to identify the risk factors of mortality. The Sensititre YeastOne microtiter panel assessed the susceptibility of antifungal agents. 



In this study, we identified 36 patients with C. guilliermondii fungemia. The median age of patients was 50.5 years (range, 17 days to 96 year) and 20 cases (56%) were male. The incidence of C. guilliermondii fungemia was 0.05 per 1000 admissions. Malignancy was the most common co-morbidity, and 25 (69%) patients had central venous catheter in place. Thirty-day overall mortality was 16.7%. In multivariate logistical regression analysis, catheter retention was an independent risk factor of mortality. According to epidemiological cutoff values, most clinical isolates (21/22, 95.5%) belonged to the wild-type MIC distributions for amphotericin B and flucytosine; however, the isolates were less susceptible to fluconazole (68%) and echinocandins (77–91%). 



Despite the lower mortality rate associated with C. guilliermondii fungemia, the removal of a central venous catheter remained an independent factor influencing the outcome of patients. The clinical significance of less susceptibility of C. guilliermondii to triazoles and echinocandins remains to be elucidated.
