Abstract
Objective: The aim of this study was to assess whether the micronutrients zinc and copper, provided by human milk additives, are sufficient for very low birth weight preterm infants.
Method: A phase 1 randomized double-blind controlled trial was conducted with very low birth weight preterm infants. This is a secondary analysis of copper and zinc. Sixty-six newborns were part of the initial sample, with forty participating and reaching the final stage of the study. Inclusion criteria were: gestational age less than 37 weeks, birth weight greater than or equal to 750 g and less than or equal to 1500 g, small or appropriate for gestational age, exclusively receiving human milk at a volume greater than or equal to 100 mL per kilogram per day, and hemodynamically stable. Participants were randomly assigned to two groups: intervention, Lioneo (received human milk with additive based on lyophilized human milk), n = 20, and control, HMCA (received human milk with commercial additive based on cow's milk protein), n = 20, and their serum levels of zinc and copper were measured on the first and twenty-first days.
Results: There was a reduction in intragroup zinc serum levels from the first to the twenty-first day of the study (p < 0.01). There was no intergroup difference. No difference was found in serum copper levels.
Conclusion: Human milk additives were not sufficient to maintain adequate zinc serum levels in very low birth weight newborns. It was not possible to affirm whether human milk additives were sufficient to maintain adequate serum copper levels in the studied sample. UTN: U1111-1220-0550.
