Mechanisms of phosphorus and calcium homeostatic disorders in the development of cardiovascular events in patients with chronic renal diseases. The role of fibroblast growth factor 23 and Klotho

Abstract

The paper deals with the analysis of studies of the role of the bone morphogenetic proteins fibroblast growth factor 23 (FGF-23) and Klothno in the development of vascular wall calcification in chronic renal disease (CRD). FGF-23 is shown to be an important phosphaturic hormone that inhibits hypercalcemic and hyperphosphatemic effects of elevated serum vitamin D concentrations. There is evidence that there is an association between high serum FGF-23 levels and vascular wall calcification irrespective of the content of phosphorus and parathyroid hormone. Most authors regard FGF-23 as a potential uremic toxin in patients with end-stage CRD. There are data that support the renoprotective value of the morphogenetic protein Klotho whose expression in CRD is decreased.
