title: Postnatal inositol levels in preterm infants.
abstract: OBJECTIVE
  To measure plasma inositol levels in preterm infants fed formula containing inositol at levels close to those in human milk.
  
  
  METHODS
  Plasma inositol levels were measured in 72 preterm infants fed formula containing 1110 mumol/L inositol and in cord blood of 12 healthy term infants. Preterm infant plasma levels were measured four times: (1) within the first 7 days of life, (2) intermediate enteral feeding, (3) at hospital discharge, and (4) 2 months after hospital discharge.
  
  
  RESULTS
  Inositol concentrations in term cord blood samples were significantly lower than in preterm initial feeding, intermediate feeding, and discharge samples. Initial concentrations in blood of preterm infants were higher than in all other groups, and were significantly lower among infants with gestational ages of 31 to 33 weeks compared with those of 28 to 30 or 31 to 33 weeks. Days of parenteral nutrition were a significant predictor of inositol levels in the full feeding sample, with lower levels associated with prolonged parenteral nutrition. Clinical outcomes were not related to plasma inositol levels.
  
  
  CONCLUSIONS
  Feeding preterm formula with inositol levels close to those reported for human milk may not prevent the postnatal decline in preterm infant plasma inositol levels.
