Abstract:
Declining renal function is an independent risk factor for all-cause mortality in cardiovascular disease. Visfatin has been described as a marker of inflammation and endothelial dysfunction, but whether circulating visfatin levels are predictive to a subsequent decline in renal function remains unclear. METHODS In total, 200 nondiabetic, non-proteinuric hypertensive outpatients with initial serum creatinine (Sc r ) ≤1.5mg/dl were enrolled. Plasma visfatin concentration and endothelial function estimated by brachial artery flow-mediated dilatation (FMD) were determined in the study subjects. The primary endpoints were the occurrence of renal events including doubling of Sc r , 25% loss of glomerular filtration rate (GFR) from baseline values, and the occurrence of end-stage renal disease during follow-up. RESULTS The mean annual rate of GFR decline (ΔGFR/y) was −1.26±2.76ml/min/1.73 m 2 per year during follow-up (8.6±2.5 years). At baseline, plasma visfatin was negatively correlated with estimated GFR. In longitudinal analysis, the ΔGFR/y was correlated with visfatin, baseline GFR, FMD, systolic blood pressure, and fasting blood glucose (FBG). Multivariate analysis indicated that increased visfatin ( r = −0.331, P & lt;0.001), baseline GFR ( r = −0.234, P = 0.001), FMD ( r = 0.163, P = 0.015), and FBG ( r = −0.160, P = 0.015) are independent predictors of ΔeGFR/y. Cox regression model analysis showed that visfatin (hazard ratio (HR), 1.09; 95% confidence interval (CI), 1.05–1.13, P & lt;0.001), FBG (HR, 1.01; 95% CI, 1.00–1.02, P = 0.020), and FMD (HR, 0.87; 95% CI, 0.76–1.00, P = 0.049) were independently associated with the risk of developing future renal events. CONCLUSIONS Increased circulating visfatin are associated with subsequent decline in renal function in nondiabetic hypertensive patients.
