Brief Summary:
An experimental mechanistic study. The overall objective is to gain new knowledge about mechanisms involved in adaptation to recurrent hypoglycaemia in diabetes by investigating patients with type 1 diabetes and healthy controls. The knowledge to be obtained may feed into experimental hypoglycaemic clamp studies to further elucidate the effect of the adaptations during acute hypoglycaemia. Ultimately, it may lead to intervention studies aiming at the maintenance of functional capability during hypoglycaemia in patients with type 1 diabetes to reduce their risk of severe hypoglycaemia.
Detailed Description:
Study rationale The risk of severe hypoglycaemia is a major daily concern for people with diabetes treated with insulin. Severe hypoglycaemia is the main barrier in achieving the recommended glycaemic targets and may indirectly be the main driver for late diabetic complications and related morbidity, mortality and health care costs. In people with diabetes, recurrent exposure to insulin-induced mild hypoglycaemia leads to significant adaptive physiologic responses. While the metabolism of the brain and hormonal responses to hypoglycaemia have been studied extensively, this study will as the first, systematically investigate the chronic adaptation of peripheral metabolism to recurrent hypoglycaemia in diabetes. Knowledge about such responses can lead to interventions that attenuate the devastating effects of acute hypoglycaemia induced by insulin in people with diabetes. Thereby, the risk of developing severe hypoglycaemia can be reduced which ultimately will improve long-term diabetes outcomes and reduce health care costs.
Hypothesis Patients with type 1 diabetes that are exposed to high-frequent recurrent hypoglycaemia will adapt their metabolism in a way, which supports the preservation of brain fuelling.
Objectives
Primary objective The overall objective is to gain new knowledge about mechanisms involved in adaptation to recurrent hypoglycaemia in diabetes by investigating patients with type 1 diabetes and healthy controls. The knowledge to be obtained may feed into experimental hypoglycaemic clamp studies to further elucidate the effect of the adaptations during acute hypoglycaemia. Ultimately, it can lead to intervention studies aiming at the maintenance of functional capability during hypoglycaemia in patients with type 1 diabetes to reduce their risk of severe hypoglycaemia.

* To study the consequences of recurrent hypoglycaemia on glucagon and adrenaline sensitivity
* To study the consequences of recurrent hypoglycaemia on epigenetic profiles
* To study the consequences of recurrent hypoglycaemia on oxidative stress
* To study the psychological factors associated with recurrent hypoglycaemia
