Pathogenesis and management of vascular calcification in CKD and dialysis patients.

Abstract

Patients with chronic kidney disease (CKD) have a predisposition to develop vascular calcification due to dysregulated homeostatic mechanisms, which lead to an imbalance in the circulatory promoters and inhibitors of vascular calcification, leading to a net calcification stress. These factors promote ectopic calcification and induce vascular smooth muscle cells to undergo osteogenic differentiation and actively calcify the vascular media. The article summarizes clinically relevant pathogenic mechanisms of vascular calcification in patients with CKD and in dialysis patients and summarizes novel therapeutic interventions. In addition to the management of traditional cardiovascular risk factors, patients with CKD-mineral and bone disorder need close attention in the management of the mineral metabolism to prevent adverse effects on the bone and vascular compartments. This article reviews current evidence and therapeutic guidelines in the management of mineral metabolism in CKD and dialysis.
