| [ Summary ] | Klotho deficiency and FGF-23 increase followed by vitamin D decrease and PTH increase are closely associated with the development of CKD-MBD. These changes are regarded as an attempt to maintain phosphorus homeostasis with reduced functional nephron number. Renal bone disease is characterized by reduced bone volume, increased woven texture of bone and microcrack, which potentially lead to bone pain and fragile bone. Various kinds of vitamin D compounds and/or calcimimetic agents have been used for the treatment of renal hyperparathyroidism, however, parathyroidectomy is often more effective for patients refractory to conservative therapy with high turnover bone disease. Post-parathyroidectomy management is also very important for the improvement of high bone turnover. In this review paper, recent progresses in basic and clinical studies and unsolved problems in CKD-MBD are discussed. | |
