    AbstractOmentin-1 regulates inflammation, lipid accumulation, endothelial dysfunction, and atherosclerosis; the latter factors contribute to the occurrence of major adverse cardiac and cerebrovascular events (MACCE). This study aimed to explore the predictive implication of serum omentin-1 for MACCE risk in patients receiving hemodialysis. A total of 319 patients receiving hemodialysis and 160 healthy controls were prospectively enrolled in this study. Omentin-1 from serum was detected by enzyme-linked immunosorbent assay. MACCE was recorded during follow-up (median 18.9 months; range 1.9-62.9 months) in patients receiving hemodialysis. Omentin-1 was reduced in patients receiving hemodialysis versus healthy controls (P < 0.001). In patients receiving hemodialysis, omentin-1 was negatively related to C-reactive protein, total cholesterol, and low-density lipoprotein cholesterol (all P < 0.05); whereas omentin-1 was not related to other clinical characteristics. Notably, the 1-year, 2-year, 3-year, 4-year, and 5-year accumulating MACCE rates in patients receiving hemodialysis were 7.9%, 18.3%, 25.9%, 36.1%, and 41.4%, respectively. Interestingly, high omentin-1 related to decreased accumulating MACCE rate (P = 0.003), which was further validated by multivariate Cox regression analysis (hazard ratio = 0.458, P = 0.006). Additionally, by direct comparison, omentin-1 was reduced in hemodialysis patients who experienced MACCE compared to those who did not (P < 0.001); meanwhile, the receiver operator characteristic curve displayed that omentin-1 had an acceptable ability to estimate MACCE risk with an area under the curve (95% confidence interval) of 0.703 (0.628-0.777). Serum omentin-1 reflects reduced inflammation and lipid accumulation, as well as predicts decreased MACCE risk in patients receiving hemodialysis.
