[Effect of the amino acid content of breast milk supplements on the amino acid profile in the plasma of newborn infants: human albumin in comparison with Eoprotin].
The influence of amino acid composition of two human milk fortifiers (Eoprotin, Milupa AG, Germany, and human albumin) on plasma amino acid profiles was studied in 28 preterm infants after a 14-day feeding period. The concentrations of total essential amino acids increased in both feeding groups significantly if compared to the period without supplementation; only the concentrations of methionine and phenylalanine in the eoprotin group and those of threonine, methionine and isoleucine in the human albumin group did not increase significantly. However, only the concentrations of isoleucine (Eoprotin: 79 +/- 19 mumol/l; human albumin: 45 +/- 20 mumol/l, p < 0.001) and methionine (Eoprotin: 26 +/- 10 mumol/l, human albumin: 16 +/- 10 mumol/l, p = 0.014) were significantly different between the two feeding groups. There was a significant correlation between the differences in the serum concentrations and the ones of each essential amino acid concentration in the fortifiers (r = 0.951). The results indicate that the amino acid composition of human milk fortifiers must be taken into consideration to achieve optimal nutritional management of preterm infants.
