[Chronic kidney disease (CKD) and bone. Impact of diabetes mellitus on the development of CKD-MBD].Clin Calcium. 2009 Apr; 19(4):502-7.CC
Chronic kidney disease-mineral and bone disorder (CKD-MBD) develops as renal function deteriorates. The presence of diabetes mellitus as comorbidity modulates the severity of CKD-MBD. The prevalence of vascular calcification, which becomes higher in diabetic CKD patients than in non-CKD counterparts, increases cardiovascular mortality in diabetic patients. The main factor which causes vascular calcification in diabetic CKD patients is poor glycemic control, in contrast to hyperphosphatemia in non-diabetic CKD patients. Diabetes directly impairs osetoblasts to decrease bone mass, suppresses bone turnover to impair bone quality by impairing secretion of parathyroid hormone and increase AGE-modification of bone collagen. Therefore, therapeutic regimens for CKD-MBD should be considered specifically for diabetic CKD patients since the mode of its development differs between diabetic and non-diabetic CKD patients.
