NCT01083043

Brief Summary

It is well known that lowering average blood glucose decreases the risk of diabetic complications involving the small vessels, such as those found in the eyes, nerves and kidney. It is less clear however, if controlling fluctuations in blood glucose will further help to prevent such complications. The purpose of this study is to examine the relationship between extreme fluctuations in glucose and damage to the blood vessel lining.

Outcome Measures

Primary Outcomes (1)

  • Serum levels of endothelial dysfunction biomarkers and glycemic variability

    The following biomarkers are studied: soluble e-selectin, vascular cell adhesion molecule-1, intercellular adhesion molecule-1 and asymmetric dimethylarginine. These analytes are highly correlated to endothelial dysfunction.

    Day 3 of study enrollment

Secondary Outcomes (1)

  • Metabolic parameters and glycemic variability

    Day 3 of study enrollment

Study Arms (1)

Type 2 Diabetes Mellitus
