    Abstract:
    Protein-energy wasting (PEW) contributes to mortality in hemodialysis (HD) patients. Adipokines regulate energy homeostasis and body weight. Circulating gelsolin can modulate inflammation and is correlated with HD mortality. Whether adipokines and gelsolin play important roles in PEW remains unclear. Based on the criteria proposed by the International Society of Renal Nutrition and Metabolism, we examined the associations between PEW and biomarkers (gelsolin, leptin, adiponectin, interleukin-6, tumor necrosis factor alpha [TNF-α]) in 188 stable HD patients. Patients with PEW had significantly lower serum leptin levels, and tended to have higher adiponectin, TNF-α, and lower gelsolin levels. Logistic regression analysis revealed that gelsolin, leptin, adiponectin, and blood urea nitrogen were independently associated with PEW score. Serum creatinine, TNF-α, gender, renin-angiotensin system (RAS) blockade, and lipid-lowering agents were not associated with PEW score. Patients on lipid-lowering agents had lower PEW scores and those with RAS blockade had higher PEW scores. Our study confirms that gelsolin, adiponectin, and leptin are significant associates with PEW in HD patients. Further understanding of how these factors contribute to PEW may help design novel therapeutic strategies for PEW in chronic kidney disease.
