Plasma insulin clearance was studied in a patient with autoantibodies to the insulin receptor, manifesting persistent hyperinsulinemia associated with alternating hyper- and hypoglycemia. In the postabsorptive period, the plasma glucose level gradually decreased. To prevent the development of hypoglycemia, glucose was infused and the glycemic level was clamped at 50 mg/dl without insulin infusion. The plasma C-peptide level was below the detectable range during the clamp, indicating no appreciable secretion of insulin. The plasma insulin level declined exponentially with a markedly prolonged disappearance rate (half-time: 3.0 h) during the study. These results indicate that hyperinsulinemia in the postabsorptive period in this patient is attributable to the impairment of plasma insulin clearance through receptor-mediated mechanisms, and also confirm that the receptor plays the principal role in plasma insulin removal.

UI MeSH Term Description Entries
D007328 Insulin A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D011972 Receptor, Insulin A cell surface receptor for INSULIN. It comprises a tetramer of two alpha and two beta subunits which are derived from cleavage of a single precursor protein. The receptor contains an intrinsic TYROSINE KINASE domain that is located within the beta subunit. Activation of the receptor by INSULIN results in numerous metabolic changes including increased uptake of GLUCOSE into the liver, muscle, and ADIPOSE TISSUE.
