title: [Osteoprotegerin and fibroblast growth factor 23 in the development of cardiovascular events in chronic kidney disease].
abstract: OBJECTIVE
  To study the role of the bone mineral metabolic mediators osteoprotegerin (OPG) and fibroblast growth factor 23 (FGF-23) in the mechanisms of cardiovascular events (CVEs) in chronic kidney disease (CKD).
  
  
  METHODS
  Sixty-eight patients (30 men and 38 women) aged 38 to 64 years (mean age 49 +/- 6.3 years) with Stages III-VD CKD were examined. The stages of CKD were determined in accordance with the NKF-K/DOQI guidelines; glomerular filtration rate was calculated using the CKD-EPI formula. Serum OPG and FGF-23 were examined in all the patients, by applying commercial enzyme immunoassay kits. Doppler echocardiography was performed to evaluate the morphofunctional state of the left ventricle (LV).
  
  
  RESULTS
  As renal failure progressed from Stage III to Stage VD CKD, the examined patients had higher serum OPG and FGF-23 concentrations. The levels of OPG and FGF-23 and the morphofunctional indicators of LV lesion, blood pressure, and anemia showed a strong direct correlation that preserved its significance in analyzing the factors in question in relation to the function of the kidneys and the pattern of cardiovascular system lesion.
  
  
  CONCLUSIONS
  The morphogenetic proteins OPG and FGF-23 seem to play a significant role not only in bone remodeling processes, but also in the development of CVEs in CKD.
