121-OR: Insulin Clearance Is an Independent Determinant of ß-Cell Cell Function in Obese Youths

Background: Hyperinsulinemia results from β-cell ompensatory adaptation to insulin resistance and reduced insulin clearance. We examined the relationship between hepatic/peripheral insulin clearance and β-cell function in lean and obese insulin sensitive (IS) and insulin resistant (IR) adolescents. Methods: A 2-step euglycemic hyperinsulinemic clamp and an hyperglycemic clamp were performed in 153 youths (73F, 14.4±3.3y) to evaluate hepatic...
