TL;DR: To improve bone mineralization, VLBW infants(<1500g) have been fed a high-protein/high-mineral formula rather than a standard formula and infants with GAA were greater on E, B, or C than S.
Abstract: To improve bone mineralization, VLBW infants(<1500g) have been fed a high-protein/high-mineral formula (E)(3.0g protein/100Kcal, 950mg/L Ca, 480mg/L P) rather than a standard formula (S)(2.2g protein/100Kcal, 510mg/L Ca, 390mg/L P). Higher urine Ca/urinary creatinine (UCa/UCr) and frequent generalized aminoaciduria (GAA) have been noted. To separate the effects of protein and mineral intake two identical high mineral formulae with lower protein levels (B=2.7g, C=2.2g/100Kcal) were studied. UCa/UCr and %, infants with GAA were greater on E, B, or C than S. On C UCa/UCr and UMg/UCr were increased and serum Ca (SCa) decreased compared to E. Serum albumin was lower on B and C than either E or S although protein content of B and C are ≥ S. PTH, BUN, HCO3 were normal and bone mineral content (BMC) and growth rates (GR) did not differ. A higher protein intake may minimize urinary calcium by increasing mineral accretion or by decreasing mineral absorption. Conversely, increased mineral content may increase protein utilization or decrease protein absorption.
