Abstract
Objective: Developmental programming alters growth and metabolic outcome in children born small for gestational age (SGA). We explored insulin and glucose metabolism in SGA children treated with a fixed GH dose over 1 year. Methods: In the North European Small for Gestational Age Study (NESGAS), 110 short SGA children received GH at 67 mu g/kg/day for 1 year. Insulin secretion was assessed by acute insulin response (AIR), insulin sensitivity (IS) by HOMA and disposition index (DI) by insulin secretion adjusted for IS. Results: First-year GH therapy led to increases in height and IGF-I standard deviation score (SDS), and reductions in IS (p < 0.0001). Compensatory increases in AIR (p < 0.0001) were insufficient and resulted in reduced... (More)
Objective: Developmental programming alters growth and metabolic outcome in children born small for gestational age (SGA). We explored insulin and glucose metabolism in SGA children treated with a fixed GH dose over 1 year. Methods: In the North European Small for Gestational Age Study (NESGAS), 110 short SGA children received GH at 67 mu g/kg/day for 1 year. Insulin secretion was assessed by acute insulin response (AIR), insulin sensitivity (IS) by HOMA and disposition index (DI) by insulin secretion adjusted for IS. Results: First-year GH therapy led to increases in height and IGF-I standard deviation score (SDS), and reductions in IS (p < 0.0001). Compensatory increases in AIR (p < 0.0001) were insufficient and resulted in reduced DI (p = 0.032). Children in the highest IGF-I SDS tertile at baseline were the least insulin sensitive at baseline (p = 0.024) and 1 year (p = 0.006). IGF-I responses after 1 year were positively related to AIR (r = 0.30, p = 0.007) and DI (r = 0.29, p = 0.005). Conclusion: In SGA children treated with a high GH dose for 1 year, baseline IGF-I levels were related to IS whilst gains in height and IGF-I responses were associated with insulin secretion. Defining heterogeneity in IGF-I in SGA children may be useful in predicting growth and metabolic response. Copyright (C) 2013 S. Karger AG, Basel (Less)
