Oral Calcitriol for Reduction of Mild Proteinuria in Patients With CKD
March 28, 2013 updated by: Jing Chen, Huashan Hospital
Phase 4 Study of Oral Calcitriol for Reduction of Mild Proteinuria in Patients With CKD
The safety and efficacy of Caltriol on mild proteinuria (<1.0g/d) reduction in CKD patients.

Status
Unknown
Conditions
Intervention / Treatment
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.
