title: Vitamin D levels in children undergoing adenotonsillectomies.
abstract: OBJECTIVE
  Because of the recent data supporting an immunoregulatory role for vitamin D, we evaluated levels of vitamin D in children undergoing adenotonsillectomies (T&A) and controls.
  
  
  METHODS
  We prospectively collected data from 47 children undergoing T&As and 15 undergoing unrelated elective procedures at a tertiary care children's hospital. Demographic and disease specific data was obtained in addition to a blood sample for the measurement of 25-hydroxy (OH)-vitamin D.
  
  
  RESULTS
  There were no differences in vitamin D levels between the groups and levels did not correlate to any disease parameters in the children undergoing T&A. The only significant differences were related to race in that African American children had significantly lower vitamin D levels compared to Caucasians.
  
  
  CONCLUSIONS
  This pilot study did not show an association between serum vitamin D and the need to have adenotonsillectomy.
