Background: Insulin resistance plays a significant role in the pathogenesis of type 2 diabetes mellitus (T2DM). Irisin, an adipo-myokine, is found to increase insulin sensitivity by adaptive thermogenesis. Various studies have found that endocrine and exocrine functions of the pancreas are affected in T2DM. This case-control study with 180 participants aimed to find any association of serum irisin with insulin resistance and pancreatic profile in newly diagnosed T2DM. Methods: Fasting blood sugar (FBS) and pancreatic profile were measured by Auto Analyzer, serum insulin by chemiluminescence assay, serum irisin by Enzyme-Linked Immunoassay (ELISA) kit, and insulin resistance by Homeostatic Model Assessment of Insulin Resistance (HOMA-IR). Results: Significantly lower irisin levels were observed in T2DM patients compared to healthy individuals (p =0.001*). A positive correlation was found between serum irisin and insulin resistance in T2DM patients, whereas a negative correlation was found in healthy controls. In some cases, serum amylase and lipase positively correlated with irisin, whereas a negative association was observed in controls. Conclusion: This study concludes a protective role for irisin in combating insulin resistance and improving pancreatic function in T2DM, but more extensive studies are required to prove it.
