title: [Clinical characteristics and pathogens of invasive fungal infections in children].
abstract: OBJECTIVE
  To study the clinical characteristics and pathogens of invasive fungal infection in children.
  
  
  METHODS
  The clinical data of 104 children who suffered from invasive fungal infections between 2008 and 2012 was retrospectively reviewed.
  
  
  RESULTS
  Of the 104 cases, 20 occurred in neonates, 48 in infants and 36 in preschool and school-aged children (old-aged children). Prematurity (70%), hyaline membrane disease (45%) and pneumonia (30%) were commonly comorbid in the neonate group. In addition, the percentage of cases receiving total parenteral nutrition was higher in the neonate group than in the other two age groups (P<0.01). Mechanical ventilation was more frequent in neonate and infant groups than in the old-aged children (P<0.01). Hematological malignancy was the most common underlying disease, and the percentage of children who had neutropenia and accepted chemotherapy was higher in the old-aged children than in the other two age groups (P<0.05). Lung infection was the most common (61.5%), followed by sepsis (14.4%) and intestinal tract infection (12.5%), while nervous system infections were found only in old-aged children. A total of 105 strains of fungi were isolated from the 104 patients, including Candida (n=90, 85.7%), Cryptococcus (n=6) and others (n=9). The most commonly isolated species was Candida albicans (n=52, 49.5%). Non-Candida albicans Candida accounted for 36.2% (n=38). The rate of susceptibility of Candida species to 5-fluorocytosine and amphotericin B was higher than fluconazole.
  
  
  CONCLUSIONS
  Invasive fungal infections can occur in children at various ages. There are differences in the risk factors for invasive fungal infections between age groups. Candida species are the main pathogens of childhood invasive fungal infections, and both Candida albicans and non-Candida albicans Candida are common. Fluorocytosine and amphotericin B are sensitive antifungal agents for infections caused by Candida species.
