摘要

Background. Ascorbic acid (AA) supplementation has been suggested to afford erythropoietin hyporesponsiveness and high levels of ferritin in haemodialysis (HD) patients. However, little is known about the possible side effects of this policy on vascular calcification (VC). VC, induced by a high-phosphate and uraemic milieu, is characterized by a passive deposition of calcium–phosphate (Ca-P) and an active transformation of vascular smooth muscle cells (VSMCs) in osteoblastic-like cells. The aim of these studies was to characterize the combined effects of AA and P on VC.
