Abstract
BACKGROUND: Candidemia in children caused by non-albicans Candida (NAC) spp is increasing in prevalence, but the relevant information is limited. METHODS: All isolates of pediatric candidemia from a medical center in Taiwan between 2003 and 2015 were enrolled. The characteristics of patients with NAC and Candida albicans candidemia (CAC) were compared. RESULTS: Among the 319 episodes of candidemia occurring in 262 patients, C albicans accounted for 46.4%. The NAC and CAC groups had no significant differences in demographics, underlying diseases, most risk factors, and clinical characteristics. Patients in the NAC group were significantly more likely to have fluconazole exposure (14.0% vs 6.8%, respectively; P = .045), and NAC species accounted for 70.2% of all recurrent episodes. NAC candidemia had a longer duration of candidemia (median, 3.0 vs 1.0 days after effective antifungal treatment, respectively; P = .001), slower responses to antifungal treatment, and a higher rate of treatment failure than CAC. However, the 2 groups had similar 30-day candidemia-attributable mortality rates. After multivariate logistic regression, longer duration of central venous catheter was the independent risk factor for NAC candidemia in children (odds ratio, 1.21; 95% confidence interval, 1.08-1.35 for every 10-day increment). CONCLUSIONS: NAC species collectively have emerged as the predominant pathogens of candidemia in children. Prolonged use of a central venous catheter is associated with an increased risk of candidemia caused by NAC species.
