[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].

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.
