Abstract
The Restoring Insulin Secretion (RISE) Study found that compared to adults (A), youth (Y) with early DM (33 Y, 104 A) or IGT (53 Y, 250 A) have higher insulin and C-peptide responses, even after adjusting for differences in insulin sensitivity. To better understand these differences, we compared mathematical modeling data from OGTTs to those from a hyperglycemic clamp within the RISE Study. Modeled measures were the dose-response relationship between glucose and insulin secretion (glucose sensitivity [GS], rate sensitivity [RS]) and the oral glucose insulin sensitivity index (OGIS). Clamp measures were insulin sensitivity (steady state glucose infusion rate/insulin [M/I]), acute (0-10 minutes) C-peptide (ACPRg) and insulin (AIRg) responses to glucose, steady-state C-peptide (SSCP) at plasma glucose of 11.1 mmol/L, and arginine-stimulated maximum C-peptide (ACPRmax) response at glucose >25 mmol/L. Linear regression models were fit to assess relationships between OGTT model and clamp measures by age group.
