Follow-up of exocrine pancreatic function in type-1 diabetes mellitus.

In a previous study, mild to moderate exocrine pancreatic insufficiency, as measured by the secretin-pancreozymin test, was found in 23 (43%) of 53 patients with type-1 diabetes mellitus. Of these 53 patients, 20 (7 of whom initially had an abnormal secretin-pancreozymin test) were available for a follow-up examination 11 years later. Of the 7 patients with abnormal exocrine pancreatic function at the first test, 5 remained abnormal and 2 became normal, whereas of the 13 patients with initially normal pancreatic function the test result remained normal in 11 patients and became abnormal in 2.

History of the European pancreatic club: the first 40 years 1965-2005. The scientific profile of the European pancreatic club and what stood the test of time.

The invited lectures, the symposia and panels and the printed abstracts of the meetings are the basis for analysis of the development of pancreatic research over the 40 years from 1965 to 2005. 245 invited lectures and 59 symposia, panels and round tables presented and discussed the latest state of the art at the meetings of the European Pancreatic Club (EPC). We analyze in detail the contributions to physiology and biochemistry of the pancreas, the neurohormonal control of pancreatic secretion, cell biology, stimulus-secretion coupling, and cell receptors.

History of the European pancreatic club: the first 40 years 1965-2005. The development of the European pancreatic club as a scientific society.

The European Pancreatic Club (EPC) was founded during a first symposium on December 9 and 10, 1965 in London (President H.T. Howat).

The [pre-] history of the incretin concept.

The discoverers of secretin already thought of the existence of a chemical excitant for the internal secretion of the pancreas. Numerous experiments have been performed and published between 1906 and 1935 testing the effect of injected or ingested duodenal ("secretin") extracts on fasting or elevated blood glucose levels of normal or diabetic animals and humans with contradictory results. In 1940, after a series of negative dog experiments performed by an opinion leader, the existence of an incretin was considered questionable and further research stopped for more than 20 years.

A 25-year follow-up study of glucose tolerance in first-degree relatives of type 2 diabetic patients: association of impaired or diabetic glucose tolerance with other components of the metabolic syndrome.

A follow-up study of first-degree relatives of type 2 diabetic patients presented the opportunity to study the association of components of the metabolic syndrome with oral glucose tolerance in these subjects. In 1992, 25 years after the first analysis of the cohort, we performed 75-g oral glucose tolerance tests and measured anthropometric data (body mass index, waist-hip ratio), insulin and C-peptide concentrations, and parameters of lipoprotein metabolism (free fatty acids, triglycerides, cholesterol, HDL cholesterol). Of 135 participants, 71 had normal glucose tolerance (GT), 22 had impaired GT, and 42 had diabetic GT (WHO 1985 criteria).
