ABSTRACT

BACKGROUND: In chronic kidney disease (CKD) cardiovascular remodeling (CVR) is very frequent compared with general population and, as suppose, may be associated with «new¼ renal risk factors. The aim of study was to estimate association of new serum biomarkers (FGF-23, Klotho) and traditional biomarker of cardiac damage-serum Troponin I (sTr-I) with signs of CVR. METHODS: One hundred thirty CKD G1-5D patients without cardiovascular disease (CVD) clinical manifestation were included. We measured serum FGF-23, Klotho and sTr-I. The instrumental methods were: echocardiography, SphygmoCor test [Pulse Wave Velocity (PWV), Central (aortic) Blood Pressure (CBP), Subendocardial Blood Supply (SBS)]. RESULTS: FGF-23 level correlated with: sTr-I (r = 0.512; p < 0.01), eccentric left ventricular hypertrophy, LVH (r = 0.543; p < 0.01), SBS (r = - 0.499; p < 0.05). There were no differences of FGF-23 level in patients with normal and high CBP. Klotho correlated with concentric LVH (r = - 0.451; p < 0.01), PWV (r = - 0.667; p < 0.001), Cardiac Calcification Score, CCS (r = - 0.581; p < 0.01). Multivariate analysis revealed positive independent association of FGF-23 with eccentric LVH (OR = 1.036, 95% CI (1.004-1.068); p = 0.038). Klotho was a negative determinant for concentric LVH (OR = 0.990, 95% CI 0.987-0.994; p < 0.001), increased PWV (OR = 0.984, 95% CI (0.977-0.991); p < 0.001) and CCS (OR = 0.991, 95% CI (0.988-0.995); p < 0.001). In addition, multivariate analysis revealed a relationship between serum Klotho (OR = 0.980, 95% CI (0.964-0.996); p = 0.016), FGF-23 (OR = 3.145, 95% CI (1.020-9.695); p = 0.046) and troponin I level. CONCLUSION: In CKD patients without CVD clinical manifestation increased serum FGF-23 level and decreased Klotho are associated with CVR: FGF-23 with eccentric LVH (independently of CBP), Klotho determinate concentric LVH, PWV and CCS. Moderately elevated sTr-I levels may be a manifestation of FGF-23/Klotho imbalance in CKD.
