Disordered glucose and insulin metabolism in patients with insulinoma. 1975

S W Shen

The response of plasma glucose and insulin to infusion of glucose and of epinephrine plus propranolol were examined in normal subjects and in two patients with surgically proven insulin-secreting islet cell tumors. The plasma immunoreactive insulin concentration in the two patients was both inappropriate and independent of the plasma glucose concentration. Their insulin secretion was neither increased by physiologic stimulants nor decreased by pharmacologic inhibitors of insulin secretion. There are diagnostic uses for these data as well as theoretical implications. We propose a physiological approach to establish the diagnosis of insulin-secreting islet cell tumors.

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).

D007516 Adenoma, Islet Cell A benign tumor of the pancreatic ISLET CELLS. Usually it involves the INSULIN-producing PANCREATIC BETA CELLS, as in INSULINOMA, resulting in HYPERINSULINISM.

D010180 Pancreatectomy Surgical removal of the pancreas. (Dorland, 28th ed) Pancreatectomies
D010190 Pancreatic Neoplasms Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
