The Effect of Rapid and Slow Glucose Fall on the Subsequent Glucose Production in People With Type 1 Diabetes — RaSlo-19  

Type 1 Diabetes Clinical Trial

Official title:
The Effect of Rapid and Slow Glucose Fall on the Subsequent Glucose Production in People With Type 1 Diabetes

Clinical Trial Summary

In the effort of better understanding the glucose control in people with type 1 diabetes, in-depth insight into the physiology of hepatic glucose production and its influencing factors is essential. Previously, a number of potential influencing factors of hepatic glucose production have been investigated, including insulin-on-board, low carbohydrate diet, preceding ethanol intake, exercise and multiple stimulations of hepatic glucose production. Previous post-hoc analysis of dual-hormone closed-loop systems has indicated that the rate of fall in blood glucose influences the following stimulation of hepatic glucose response. However, the rate of fall in blood glucose is highly related to insulin levels, which may explain those findings. Thus, in this study the investigators want to examine whether the different rates of fall in blood glucose with similar insulin levels on board affect the hepatic glucose response in individuals with type 1 diabetes. In the study, which will be conducted at Steno Diabetes Center Copenhagen, participants will complete two study visits. On each visit, a hypoglycemic clamp technique will be used to lower the blood glucose levels of the participants (using either a rapid or slow decline rate), whereupon hepatic glucose production will be stimulated using low-dose glucagon. The study days are divided into four phases: 1) preparation phase, 2) hyperinsulinemic euglycemic phase (stabilization of blood glucose), 3) hyperinsulinemic hypoglycemic phase (rapid or slow decline in blood glucose) and 4) post-glucagon administration phase. This design will allow the investigators to examine whether differences in hepatic glucose response exist depending on preceding rate of fall in blood glucose. We hypothesize that the rate of fall in blood glucose does not affect the hepatic glucose production.
