Irisin and Triglyceride Glucose Index as Markers of Dyslipidemia in Young Adults

Indian J Clin Biochem. 2024 Jan;39(1):136-141. doi: 10.1007/s12291-022-01083-3. Epub 2022 Sep 6.ABSTRACTIrisin, is a new myokine, considered a favorable metabolic factor and inversely associated with non-communicable diseases. The biological activities of irisin are currently unknown; however, they include browning white adipose tissue, insulin sensitivity, and anti-inflammatory and antioxidant effects. Triglyceride glucose index is a notable insulin resistance marker that predicts the risk of metabolic dyslipidemia and cardiovascular risk. The study aimed to evaluate the relation of irisin and Triglyceride glucose index (TyG) in young adults to assess the cardiovascular risk. This observational cross-sectional study included 80 participants aged 18 to 35 years (male and females) with cut-off TyG > 4.5 as the prime criteria. With consent, anthropometric measurements were documented. Fasting lipid profile parameters were analyzed, and atherogenic lipid ratios and TyG index were calculated. Serum irisin was analyzed in Bio-Rad ELISA using a standardized Abbkine kit. Decreased irisin levels (0.32 ± 0.04ng/ml) and increased TyG index (4.95 ± 0.012) were observed in the participants with elevated triglyceride levels. The lipid profile parameters and atherogenic lipid ratios were observed to be elevated in males as compared to females. Correlation of irisin with lipid parameters revealed statistically significant positive correlation with HDLc (r = + 0.305) and negative correl...
