Asprosin is positively associated with metabolic syndrome in hemodialysis patients: a cross-sectional study

Abstract

AbstractIntroduction Metabolic syndrome (MS) has a high prevalence in hemodialysis patients. High asprosin levels are associated with the accumulation of adiposity and an increase in body weight, which may drive the development of this syndrome. The relationship between asprosin and MS in patients on hemodialysis has not been investigated.Materials and Methods We enrolled hemodialysis patients at the hemodialysis center of one hospital in May 2021. MS was defined by the International Diabetes Federation. Fasting serum asprosin levels were measured. ROC curve, multivariate logistic regression and Spearman’s rank correlation analyses were performed.Results In total, 134 patients were included, with 51 with MS and 83 without MS. Among the patients with MS, there was a significantly higher proportion of women (54.9%), prevalence of DM (p < 0.001), waist circumference (p < 0.001), BMI (p < 0.001), triglycerides (p < 0.001), and low-density lipoprotein cholesterol(p < 0.050), and PTH (p < 0.050) contents and a lower diastolic pressure(p < 0.050) and high-density lipoprotein cholesterol level (p < 0.001) than those in patients without MS. The patients with MS exhibited significantly higher serum asprosin levels than the non-MS patients [502.2 ± 153.3 ng/ml vs. 371.5 ± 144.9 ng/ml, p < 0.001]. The AUC for the serum asprosin level was 0.725 (95% confidence interval: 0.639, 0.811). Multivariate logistic regression analysis revealed that asprosin was independently and significantly positively associated with MS (OR = 1.008, p < 0.010). Asprosin levels tended to rise as the number of diagnostic criteria of MS increased (p for trend <0.001).Conclusions Fasting serum asprosin is positively correlated with MS and could be an independent risk factor for MS in hemodialysis patients.
