Brief Summary:
Patients accepted for the waiting list for single pancreas transplantation suffer from severe glucose instability with hyperglycemia due to diabetes type 1, but do not have significant diabetes-related complications. Pancreas transplantation restores normoglycemia in diabetes type 1 patients with unstable control of glycemia. Both hypo- and hyperglycemic events are abolished, and 70-80 % of the patients obtain satisfactory HbA1c levels (HbA1c 5.0-6.0 %) without the need of exogenous insulin. Endothelial dysfunction is considered as an early and potentially reversible stage in the atherosclerotic process. The endothelium is involved in homeostasis, leucocyte adhesion and vasomotor activity. Reduced endothelium-dependent vasodilation is associated with increments in cardiovascular risk factors, and endothelial dysfunction is a predictor for future cardiovascular disease. It has also been hypothesized that endothelial dysfunction may be involved in the impaired glycemic control by reducing the availability of glucose in peripheral muscles.Establishing normoglycemia by pancreas transplantation alone in previously diabetic type 1 patients has recently been shown to improve left ventricular ejection fraction, assessed by Doppler echocardiographic examination. In diabetic patients receiving a new pancreas it is possible to assess the effect of changing blood glucose excursions on cardiovascular risk factors, including endothelial function, without the use of antidiabetic drugs (exclude pleiotropic effects).
The primary objective of the present study is to assess if endothelial function (assessed by flow-mediated dilatation of arteria brachialis) is improved when hyperglycemia is reversed by single pancreas transplantation in patients with type 1 diabetes.
Secondary objectives are to investigate the changes in the following parameters by reversal of hyperglycemia by pancreas transplantation; Peripheral arterial tonometry, serum/plasma concentrations of endothelial dysfunction markers, blood pressure, lipid and lipoprotein concentrations.
