Cardiovascular risk profile after simultaneous pancreas and kidney transplantation.

The positive influence of simultaneous pancreas and kidney transplantation (PKT) on the development of diabetic microvascular lesions is well established. On the other hand, little is known on its impact on diabetic macrovascular disease, which is still the major cause of death in diabetes, including patients after PKT. In order to evaluate the influence of PKT on the cardiovascular risk profile, we performed a cross-sectional study on 55 patients.

Impact of pancreas and kidney transplantation on determinants of blood and plasma viscosity.

Simultaneous pancreas and kidney transplantation (PKT) is associated with a deterioration of hemorheology. We investigated the determinants of plasma and blood viscosity (hct. 35%) after PKT (n = 49), in type 1 diabetes (n = 26) and in healthy controls (n = 24).

Formation of plasma advanced glycosylation end products (AGEs) has no influence on plasma viscosity.

Plasma viscosity is mainly determined by large non-spherical proteins. In Type 1 diabetes mellitus, plasma viscosity increases with deterioration of diabetic control. Since protein glycation and formation of advanced glycosylation end products (AGEs) alter the structural and functional properties of proteins, AGEs might influence the rheological properties of plasma proteins.

Influence of glycemic control on viscosity and density of plasma and whole blood in type-1 diabetic patients.

The hemorheological properties of blood play an important role in determining blood flow. Blood inertia, as characterized by blood density, controls blood flow in the large arteries, whereas blood viscosity becomes increasingly important with decreasing vessel diameter. In order to evaluate the impact of glycemic control on the rheological properties of blood, we examined viscosity (shear range: 600-0.
