To elucidate the association between serum sclerostin and vascular calcification (VC) in maintenance dialysis patients with chronic renal failure (CRF). Methods?? Blood samples were collected from 94 maintenance dialysis patients at our hospital between March and May 2017 and the related clinical biochemical data were measured using standard auto-analyzer techniques. Serum sclerostin level was measured using a quantitative sandwich enzyme-linked immunosorbent assay (ELISA) method. Chest computed tomography (CT) was performed to measure VC. The association between sclerostin level and VC was analyzed. Results?? Serum sclerostin level was significantly higher in dialysis patients with VC than in those patients without VC [(121.23±53.13) vs. (81.84±30.20)pmol/L, P<0.01]. The serum sclerostin level (OR=1.038, P<0.01) was associated with VC determined by multivariate logistic regression. Receiver operating characteristic curve suggested that the cut-off number of sclerostin level predicting VC was 91.27pmol/L, and the sensitivity and specificity were both 0.71. The sensitivity was 0.91 and the specificity was 0.74 when sclerostin level was combined with age, diabetes, calcium and iPTH to predict VC. Conclusion? ?Serum sclerostin level is higher in dialysis patients with VC compared with those without VC, and it is associated with VC in dialysis patients, suggesting that it has some value in predicting VC %K sclerostin %K 慢性肾衰竭 %K 维持性血液透析 %K 血管钙化< %K br> %K sclerostin %K chronic renal failure %K dialysis %K vascular calcification %U http://yxxb.xjtu.edu.cn//oa/darticle.aspx?type=view&id=201803011
