Brief Summary:
The purpose of this study is to obtain information on whether raising levels of HDL-cholesterol (the "good" cholesterol) can improve how blood vessels work in kidney disease. This may help us understand the causes leading to high rates of heart disease in kidney disease and also ways to reduce this risk.
