Non-insulin dependent diabetes mellitus (NIDDM) is characterized by a specific defect in glucose recognition by the pancreatic islet beta cell. This is in clear distinction to patients with insulin dependent diabetes mellitus (IDDM) who undergo pancreatic islet beta cell death and no longer have the ability to synthesize, store, and release insulin. Defective glucose-induced first phase insulin responses in patients with NIDDM can be partially restored by exogenous insulin treatment and by other pharmacologic therapy. Thes observations provide strength for the theory of glucose desensitization of the pancreatic beta cell as an important secondary defect in the pathogenesis of abnormal insulin secretion in NIDDM. However, even though defective insulin secretion is an essential part of the pathogenesis of NIDDM, in itself it is not sufficient. A multiplicative effect is required involving interaction between tissue resistance to insulin action and defective insulin secretion whose product is the syndrome of NIDDM.
