CONTEXTNesfatin-1 is a neuroendocrine peptide with potent anorexigenic activity in rodents. The potential role of nesfatin-1 on the regulation of energy balance, metabolic functions and inflammation is currently debated in obese humans. In the present study, nesfatin-1 fluctuations and their associations with metabolic factors were investigated in severely obese patients who underwent biliopancreatic diversion with duodenal switch (BPD/DS) and severely obese controls (SOC).BASIC PROCEDURESSixty severely obese patients who underwent BPD/DS and 15 SOC (matched for BMI and age) were included in the study. Associations between nesfatin-1 levels and body composition, glucose metabolism, lipid profile as well as inflammatory markers were evaluated at baseline and over a post-surgery12-month (12M) period.MAIN FINDINGSBody weight was reduced at 6M and at 12M in BPD/DS patients (P<0.001). Nesfatin-1 levels were reduced at 6M (women: P<0.05) and at 12M (men and women; P<0.001) in BPD/DS patients. At baseline, nesfatin-1 levels negatively correlated with weight, fat (FM) and fat-free mass (FFM) in the whole population (combined BPD/DS and SOC patients). At 12M, nesfatin-1 concentrations positively correlated with weight, FM, fasting insulin, insulin resistance, total cholesterol, LDL-cholesterol, triglyceride and apoB values. At 12M, % changes in nesfatin-1 were positively associated with % changes in weight, FM, FFM, fasting insulin, insulin resistance, total cholesterol, LDL-cholesterol, apoB and C-reactive protein.CONCLUSIONNesfatin-1 levels decrease following BPD/DS-induced weight loss and are significantly associated with parameters of metabolic health.
