Detailed Description:

Proteinuria is not only a capital sign of kidney disease, but also a marker of chronic kidney disease (CKD) progression. Emerging evidence in patients with CKD show that vitamin D and its analogs can reduce proteinuria or albuminuria in the presence of angiotensin-converting enzyme inhibithion. While some of the studies reported that vitamin D receptor activation has been associated with increased serum creatinine and reduced estimated glomerular filtration rates. Therefore, the investigators plan to conduct a randomized clinical study to evaluate the efficacy and safety of Calcitriol in the treatment of mild proteinuria (<1.0g/d) CKD patients,which has no specific treatment at present.
