Blood biochemical profile of very preterm infants before and after trophic feeding with exclusive human milk or with formula milk.

Objectives: To determine whether feeding type of trophic feeds affect haematological and biochemical markers in the very preterm infant.

Design And Methods: Fifty-six very preterm infants were enrolled in this retrospective study (30 infants were included in the only human milk-fed group and 26 in the formula-fed group). Routine haematological and biochemical variables were collected in both groups on days 1 and 4 of life and fourteen serum markers were measured.
