Conclusions
At the 6th IDF Congress in Stockholm in 1967, a hypothesis for the pathogenesis of maturity-onset diabetes under the title ‘What is inherited — what is added?’ was put forward.
Investigations over the past 10 years, on the whole, tend to confirm our concept that the capacity of the pancreatic beta-cell to respond to a standardized glucose infusion with insulin production, to a major degree, is genetically controlled. Therefore, our original idea that impaired insulin response to glucose is a marker of genetic diabetes in all its stages (prediabetes, chemical diabetes, manifest diabetes) seems plausible. Accordingly, a malfunction in the transmission of information about the blood glucose level in the extracellular fluid to those sites in the cells which regulate insulin release, would be the primary defect in genetic diabetes.
Our studies suggest that, due to increased sensitivity of the liver to insulin in the portal vein, most prediabetics retain a relatively normal — although somewhat low — glucose tolerance. This compensatory mechanism becomes insufficient and glucose intolerance is precipitated, e.g., when the demand for insulin release is increased. This occurs when the sensitivity of the body for insulin diminishes as in the case of obesity, acromegaly and pregnancy and, maybe, also during the process of aging.
