Diabetic Nephropathy and other proteinuric renal diseases are the major cause of kidney disease in the United States. The degree of proteinuria is associated with risk for renal disease progression and cardiovascular outcomes. Deficiency of 1-25 Vitamin D develops early in CKD, and is undertreated. Vitamin D may have important effects on factors that drive proteinuria and renal disease progression in patients with proteinuric renal diseases. Therefore, Paricalcitol treatment may reduce proteinuria and slow renal deterioration.
