Evidence suggests a hormone peptide named adropin, is involved in lipid metabolism, insulin resistance, and obesity. However, its role in pathogenesis of type 2 diabetes mellitus (T2DM) is still unclear in humans. Therefore, we investigated whether adropin levels are altered in T2DM patients, and evaluated its association with diabetes- related parameters. Samples which collected from 180 subjects were divided into case group [n = 90] and control groups [n = 90]. The mean age was [43.17 ±11.13] years. Men (n=81) and femanl (n=99) were participated in case-control study. Serum adropin levels were determined by ELISA. The mean serum adropin level was significantly higher [P<0.01] in the control group compared to case group [6.9±1.3 vs. 5.8±1.2] respectively. The result shown there was a significant difference [P-value<0.001] between body mass index and adropin. adropin with high significant negative correlation [P-value<0.001] between adropin and body mass index, fasting blood sugar, glycated hemoglobin, insulin, and homeostatic model assessment for insulin resistance also a significant negative correlation was found between the adropin and low-density lipoprotein, triglyceride, very low-density lipoprotein and no significant with cholesterol, high-density lipoprotein.
