Changes in insulin sensitivity and glucose metabolism during therapy with recombinant human growth hormone in short children born small for gestational age show a negative correlation with baseline measurements.
Recombinant human growth hormone (rhGH) is an effective therapy for children with short stature born small for gestational age (SGA); however, insulin resistance can develop during treatment. This retrospective analysis assessed the effect of rhGH treatment (0.067 mg/kg/day) on glucose metabolism and insulin secretion in children with short stature born SGA, and measured whether baseline characteristics correlated with changes in insulin resistance or glucose sensitivity during treatment. Baseline glucose area under the concentration-time curve (AUC) was negatively correlated with the change in glucose AUC (p<0.001). Similar negative correlations were seen between baseline insulin AUC and the change in insulin AUC during treatment (p<0.001); and between baseline HOMA-IR (homeostatic model of insulin resistance) and the change in HOMA-IR during treatment (p<0.001). Small but significant changes, not thought to be clinically significant, were seen in indicators of insulin sensitivity during rhGH treatment. Glucose levels remained within the normal range during oral glucose tolerance testing.
