[The efficacy and safety of activated vitamin D for CKD-MBD]

Metabolic bone disorders that are represented by secondary hyperparathyroidism occur with the progression of chronic kidney disease(CKD). The administration of activated vitamin D is expected to improve high-turnover bone disorders and is widely used for the management of bone mineral diseases in patients with CKD and end-stage renal disease. CKD is an underlying disease of secondary osteoporosis and coexists with primary osteoporosis at a high rate. With regard to osteoporosis patients with renal insufficiency, the administration of activated vitamin D is also thought to reduce the fracture incidence by both increasing bone mass and reducing falls.
