AbstractThis study was planned to investigate the relationship between birth weight and insulinlike growth factor-I (IGF-I),IGF binding protein-3 (IGFBP-3), and leptin levels in neonates with normal growth (appropriate for gestational age: AGA) and retarded growth (small for gestational age: SGA); and to evaluate these growth factors’ effects in early postnatal growth. All newborns were full-term: gestational age 38-41 weeks. Of 50 neonates, 25 were SGA. IGF-I, IGFBP-3 and leptin levels were measured in maternal serum and venous cord blood at birth and at 15 days of life of neonates using specific RIAs. Maternal serum leptin concentrations were significantly higher than cord blood leptin concentrations (p <0.001). Maternal serum IGF-I, IGFBP-3 and leptin levels did not show correlations with birth weight. In contrast, there were significantly positive correlations between birth weight and venous cord blood IGF- I, IGFBP-3 and leptin levels (p <0.001). In the SGA group, the newborns with a slow postnatal growth pattern had lower umbilical cord serum IGF-I levels compared with newborns with a normal growth pattern. A similar result was also found in the AGA group. Similar results were not found for serum leptin and IGFBP-3.In conclusion, cord blood IGF-I, IGFBP-3 and leptin levels play an important role in the regulation of fetal and neonatal growth. It is likely that IGF-I has a more important role than the other factors in early postnatal growth.

Low Birth Weight Infants

Concentrations of 11 plasma proteins were measured in 28 healthy, growing, very low birth weight, appropriate-for-gestational-age infants fed varying levels of human milk protein intake (range 1.7 to 3.9 g/kg per day). Significant positive correlations were found between ween mean protein intake and concentrations of 7 of the plasma proteins studied (transthyretin, retinol-binding protein, and transferrin: P &lt; .001; vitamin D-binding protein and apolipoprotein B: P &lt; .01; albumin and apolipoprotein A I: P &lt; .05). A weak negative correlation with mean protein intake was seen for the plasma level of orosomucoid, whereas no significant correlations were found for the plasma concentrations of fibronectin and α1-antichymotrypsin. Protein intake, not energy intake, constituted the main contribution to the changes in the concentrations of transthyretin, retinol-binding protein, and transferrin. The levels of plasma transthyretin and transferrin were also strongly correlated with weight and length growth of the infants during the study as well as with other indicators of protein nutritional status such as preprandial concentrations of plasma amino acids and serum and urine urea. These data indicate that of the 11 plasma proteins studied, transthyretin, transferrin, and retinol-binding protein are the most suitable to evaluate protein nutritional status in very low birth weight infants.
