Background: An exclusive human milk-based diet has been shown to decrease necrotizing enterocolitis and improve outcomes for infants ≤1250 g birth weight. Studies have shown that infants who received an exclusive human milk diet with a donor-human milk-derived cream supplement (cream) had improved weight and length velocity when the cream was added to mother's own milk or donor-human milk when energy was <20 kcal/oz using a human milk analyzer. Our objective was to compare growth and cost outcomes of infants ≤1250 g birth weight fed with an exclusive human milk diet, with and without human milk cream, without the use of a human milk analyzer., Methods: Two cohorts of human milk-fed premature infants were compared from birth to 34 weeks postmenstrual age. Group 1 (2010-2011) received a donor-human milk fortifier, whereas Group 2 (2015-2016) received donor-human milk fortifier plus the commercial cream supplement, if weight gain was <15 g/kg/d., Results: There was no difference in growth between the 2 groups for weight (P = 0.32) or head circumference (P = 0.90). Length velocity was greater for Group 1 (P = 0.03). The mean dose of donor-human milk fortifier was lower in Group 2 (P < 0.001). Group 2 saved an average of $2318 per patient on the cost of human milk products (P < 0.01)., Conclusions: Infants receiving a human milk diet with cream supplementation for growth faltering achieve appropriate growth in a cost-effective feeding strategy., (© 2019 American Society for Parenteral and Enteral Nutrition.)

Objective: To evaluate the growth of premature infants fed a postdischarge diet of human milk (HM) complemented with transitional formula (TF) as compared with those fed TF only., Study Design: In this prospective cohort study, 51 infants' diets and anthropometrics were collected at discharge and at 12-15 months corrected gestational age., Results: Post discharge, infants in both groups exhibited similar growth velocities and changes in z-scores. The duration of infants' HM consumption was not correlated with weight gain (r = -0.25, p = 0.26). The duration of complementary TF feeds also did not correlate with increased growth (r = -0.11, p = 0.44). Both groups achieved catch-up growth and displayed growth velocities that significantly exceeded the upper limit of the World Health Organization (WHO) weight growth standard (p < 0.001)., Conclusions: Preterm infants receiving HM and complementary TF post discharge had growth velocities at or exceeding weight gain projected by the WHO growth standard for term infants.
