Abstract
BACKGROUND: Candida species is an important cause of nosocomial infection in neonatal intensive care units (NICUs). However, most reports in China have been limited to single institutions. The aim of this study is to investigate the epidemiology of invasive candidiasis in multiple NICUs across China. METHODS: We retrospectively collected demographic data, clinical characteristics, microbiological results and outcome of preterm infants with invasive candidiasis discharged from 11 academic tertiary NICUs during January 2009 to December 2011. RESULTS: There were 30,045 preterm infants discharged from 11 NICUs during the study period. We detected 223 infants with invasive candidiasis, resulting in an incidence of 0.74 cases per 100 preterm discharges from NICUs. In very low birth weight infants, the incidence was 3.42 cases per 100 very low birth weight discharges. Mean gestational age of infected infants was 31.4 weeks and median birth weight was 1410 gram. Among the cohort of infants with invasive candidiasis, 214 (96.0%) infants had positive blood culture for fungus, 5 infants had positive urine culture, 3 from cerebrospinal fluid and 1 from articular effusion in the shoulder joint. Among the cohort of infants with candidemia, 48 (22.4%) infants had fungal meningitis. Candida albicans accounted for 57.4% of total positive cultures. Overall mortality attributable to invasive candidiasis was 19.3%. CONCLUSIONS: Invasive candidiasis is a common problem among preterm neonates in China, especially among very low birth weight infants and it is associated with a high mortality. The preponderance of infections was due to Candida albicans.
