Human milk-derived versus bovine milk-derived fortifier use in very low birth weight infants: growth and vitamin D status.

Background: Human milk-derived fortifier (HMDF) coupled with human milk feeding in extremely premature infants reduces the adverse outcome risks of early exposure to bovine milk ingredients but may not provide enough nutrients for adequate catch-up growth compared with bovine milk-derived fortifier (BMDF).

Objective: This study aims to compare HMDF and BMDF effects on growth parameters and serum 25-hydroxy vitamin D (25OHD) levels in preterm very low birth weight (VLBW) infants during the first 8 weeks of life.

Methods: We present a retrospective chart review of inpatient VLBW infants with birth weight <1,500 g and gestational age <32 completed weeks who received either their mother's milk or donor breast human milk fortified with HMDF or BMDF for the first 8 weeks.

Serum 25 Hydroxy Vitamin D Levels in Very Low Birth Weight Infants Receiving Oral Vitamin D Supplementation.

Background And Objective: Vitamin D supplementation in preterm infants has been recommended by American Academy of Pediatrics (AAP); however, its efficacy and safety has not been well studied. To study 25-hydroxy vitamin D (25OHD) levels as a marker of vitamin D status of very low birth weight infants while on vitamin D supplementation during neonatal intensive care unit hospitalization.

Methods: Retrospective study of preterm infants with birth weight <1500 g admitted to our unit from January 2013 to December 2015 who were on oral vitamin D3 400 IU supplementation.

Vitamin D Intake in Very Low Birth Weight Infants in Neonatal Intensive Care Unit.

It is unknown how often preterm infants in neonatal intensive care units achieve the American Academy of Pediatrics-recommended daily intake of 400 international units of Vitamin D. We studied 378 preterm infants with birth weight 1500 g or less admitted to our neonatal intensive care unit, 151 infants before and 227 infants after daily vitamin D-intake monitoring was introduced. Infants were stratified into 2 groups: extremely low birth weight (<1000 g) and Very low birth weight (1000-1500 g).
