title: Serum alpha-tocopherol concentrations in preterm infants receiving less than 25 mg/kg/day alpha-tocopherol acetate supplements.
abstract: Alpha-tocopherol (aT) concentrations were determined in 52 preterm infants receiving less than 25 mg/kg/day alpha-tocopherol acetate (aTA) supplements through intravenous hyperalimentation solutions, lipid, and oral aTA. One fourth of the study infants had aT concentrations greater than 3.5 mg/dl at least once, and an association between concentrations greater than 3.5 mg/dl and necrotizing enterocolitis was demonstrated. In contrast, another one fourth of the infants' concentrations remained less than 0.5 mg/dl through the first postnatal week. The highly variable serum tocopherol concentrations correlated with total serum lipid content but not with plasma aTA hydrolysis activity.
