title: Occurrence of infection among children with nephrotic syndrome during hospitalizations.
abstract: OBJECTIVE
  The present study was conducted to investigate the trends of childhood nephrotic syndrome (NS) admissions and factors associated with childhood NS admissions with major infections in Taiwan.
  
  
  METHODS
  A retrospective analysis was performed using Taiwan National Health Research Insurance Database (NHIRD) to explore the associated factors and health care burden for childhood NS admissions with major infections in 1997 to 2007.
  
  
  RESULTS
  Of 133,927 children, a total of 176 children had NS, which incurred 508 hospital admissions. Nineteen percent of admissions were associated with major infections. Pneumonia was the most common infection (49%), followed by urinary tract infection (UTI), bacteraemia/sepsis, peritonitis and cellulitis. Pneumonia was the most common infection among children age younger than 10 years, whereas UTI was more common among children aged greater than 10 years. NS admission with infections had longer periods of hospital length of stay and higher hospital total costs compared to those without infections. Regression analysis reveals that younger age, regional hospitals, admission hospital located in middle and south areas and admission made in spring were associated with increased risk for developing major infections.
  
  
  CONCLUSIONS
  While 19% of childhood NS admissions were associated with major infections, young age, admissions made in spring, located in middle and south Taiwan and in regional hospitals were the major associated factors for infection. Age plays an important role in risk and types of infection.
