Counter-Regulatory Impairment and the Effect of Microvascular Insulin Transfer in Type 1 Diabetes Mellitus
Completed · Not applicable
Conditions studied: Diabetes Mellitus, Type 1
In brief
The researchers plan to test the following hypothesis: A good level of glucose control in Type 1 Diabetes Mellitus (T1DM) is dependent on two levels of feedback from the body: 1. the transport of insulin through small blood vessels: suggesting that hypoglycemia leads to increased insulin sensitivity which then causes recurrent hypoglycemia; 2. the endocrine level, defined as insulin-glucose interaction and hormonal counter-regulation. The researchers plan to investigate the relationships between hypoglycemia, insulin transport, and counter-regulation. This study will ultimately lead to a better understanding of risk for recurrent hypoglycemia.

You may qualify if…
- Participated in and satisfied all of the inclusion criteria of NCT00315939
- 18 years of age or older
- Have Type 1 Diabetes Mellitus defined by American Diabetes Association criteria or judgment of physician
- Since our major goal is the investigation of hypoglycemia, we will preferentially recruit patients with a history of severe hypoglycemia/moderate hypoglycemia anticipating that approximately (\~) half of the recruited subjects will have had two or more severe or moderate hypoglycemia episodes in the past 12 months
