Title: A novel appetite peptide, nesfatin-1 in patients with non-alcoholic fatty liver disease.
Abstract: BACKGROUND AND AIMS: Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver pathology worldwide and is strongly associated with obesity and insulin-resistance and food intake. Nesfatin-1 is a new peptide that controls appetite and food intake. The objective of this research was to examine the serum concentrations of nesfatin-1 in NAFLD. MATERIAL AND METHODS: Thirty NAFLD patients who had elevated liver enzymes and 40 age- and sex-matched healthy subjects were included in this study. NAFLD was diagnosed and graded with the findings of liver ultrasound scan. Nesfatin-1 concentrations were measured using an ELISA method and the relationship between nesfatin-1 and metabolic parameters were investigated. The subjects were divided into two groups according to their body mass index (&#8805;&#8201;30 and <&#8201;30) and nesfatin-1 concentrations were examined between both groups. RESULTS: Serum nesfatin-1 concentrations in NAFLD patients were lower than healthy controls (0.26&#8201;&#177;&#8201;0.14 ng/ml, 0.38&#8201;&#177;&#8201;0.18 ng/ml, respectively, and p =&#8201;0.008). We found a negative correlation between nesfatin-1 and fasting glucose and body mass index. In obese subjects, serum nesfatin-1 concentrations were significantly lower when compared with non-obese subjects (0.26&#8201;&#177;&#8201;0.12 ng/ml, 0.37&#8201;&#177;&#8201;0.19 ng/ml, respectively; p =&#8201;0.014). In addition, we showed that nesfatin-1 concentrations in subjects with insulin resistance were significantly lower in comparison with insulin-sensitive ones (0.27&#8201;&#177;&#8201;0.17 ng/ml, 0.38&#8201;&#177;&#8201;0.17 ng/ml, respectively; p =&#8201;0.015). CONCLUSION: Our study has shown that nesfatin-1 concentrations were reduced in NAFLD. The results of this study indicate that nesfatin-1 may have a significant role in NAFLD.
