Abstract
BackgroundAsprosin, a newly identified adipokine, is pathologically increased in individuals with insulin resistance. However, the available evidence on the association of asprosin and type 2 diabetes mellitus (T2DM) status is still scarce. Therefore, this study aimed to determine the relationship between serum concentrations of asprosin and T2DM status.MethodsThis observational study was performed based on 194 adults (97 newly diagnosed T2DM and 97 healthy individuals). Anthropometric and biochemical variables were determined in all participants. Serum concentrations of asprosin were measured using enzyme-linked immunosorbent assay (ELISA).ResultsIn patients with T2DM, the serum concentrations of asprosin were significantly higher than the healthy controls (4.18 [IQR: 4.4] vs. 3.5 [IQR: 1.85], P < 0.001). The concentrations of asprosin were significantly correlated with body mass index (BMI) and fasting blood glucose (FBG) in healthy subjects and with BMI, FBG, hemoglobin A1c (HbA1c), homeostatic model assessment of insulin resistance (HOMA-IR), and quantitative insulin check index (QUICKI), triacylglycerol (TAG) and total cholesterol/high-density lipoprotein cholesterol (TC/HDL-C) ratio in the T2DM group. In fully adjusted model, the odds ratio (OR) of T2DM with serum concentrations of asprosin was approximately 1.547 (95% CI 1.293–1.850, P < 0.001) compared to the control group. Multiple stepwise regression analysis indicated that FBG and HOMA-IR were independently associated with asprosin in T2DM.ConclusionOur findings indicated that serum concentrations of asprosin are increased in patients with T2DM. Also, asprosin is correlated with insulin resistance and TC/HDL-C ratio (atherosclerotic risk factor of cardiovascular diseases) in patients with T2DM.
Highlights
Asprosin, a newly identified adipokine, is pathologically increased in individuals with insulin resistance
fasting blood glucose (FBG), hemoglobin A1c (HbA1c), TAG, LDL-C and fasting insulin concentrations, LDL-C/high-density lipoprotein cholesterol (HDL-C) and total cholesterol (TC)/HDL-C ratio and homeostatic model assessment of insulin resistance (HOMA-IR) were significantly higher in patients with type 2 diabetes mellitus (T2DM) than in the control group
We found that only in T2DM patient HbA1C, HOMA-IR, quantitative insulin check index (QUICKI), TAG and TC/HDL-C are in correlation with asprosin in serum
Summary
A newly identified adipokine, is pathologically increased in individuals with insulin resistance. The available evidence on the association of asprosin and type 2 diabetes mellitus (T2DM) status is still scarce. Adipokines are cytokines secreted from adipose tissue, which affect a broad spectrum of biological processes [4,5,6,7]. Some of these adipokines, such as resistin and leptin, antagonize insulin function in peripheral tissues, especially in the liver and skeletal muscles, which leads to insulin resistance [7,8,9,10]. The balance between adipokines is thought to play an important role
