Evaluation of serum levels of Irisin as a marker of endothelial dysfunction in patients with type 2 diabetes mellitus

INTRODUCTION: Insulin resistance and obesity have been associated with irisin, a protein in fat cells. The levels of irisin in patients with type 2 diabetes mellitus (T2DM) were significantly lower than those in non‐diabetics. This study aimed to examine the relationship between serum irisin levels...

Sumario:INTRODUCTION: Insulin resistance and obesity have been associated with irisin, a protein in fat cells. The levels of irisin in patients with type 2 diabetes mellitus (T2DM) were significantly lower than those in non‐diabetics. This study aimed to examine the relationship between serum irisin levels and endothelial dysfunction in patients with T2DM. METHODS: There were 90 participants in this study. We matched 65 patients with T2DM with 25 healthy control participants. A series of tests were performed on the participants, including fasting blood glucose, 2 hours postprandial blood glucose, glycated haemoglobin, triglycerides (TG), total cholesterol, high‐density lipoprotein cholesterol (HDL‐C), low‐density lipoprotein cholesterol (LDL‐C), TG/HDL‐C ratio and albumin/creatinine ratio. In addition to measuring high‐sensitivity C‐reactive protein (hs‐CRP). Enzyme‐linked immunosorbent assay (ELISA) technique was used for estimating irisin concentrations. RESULTS: Flow‐mediated dilation (FMD) was significantly lower in patients with T2DM; however, there was a non‐statistically significant difference between healthy controls and patients with T2DM regarding serum Irisin level. CRP and LDL levels were inversely correlated with circulating irisin levels. In a stepwise regression analysis, only the hs‐CRP and LDL were statistically significant in predicting irisin level. CONCLUSIONS: In patients with T2DM, serum levels of irisin were inversely correlated with hyperglycaemia, body mass index and per cent body fat; this suggests that detecting irisin levels early can prevent cardiovascular diseases from progressing. According to the study results, serum irisin serves as a predictive marker for early cardiovascular disease, thus preventing the disease from progressing. There is a need for further research in order to understand how irisin contributes to the development of atherosclerosis and the development of diabetic complications.
