ASSOCIATION BETWEEN NONALCOHOLIC FATTY PANCREATIC DISEASE AND TRIGLYCERIDE/GLUCOSE INDEX

•Non-alcoholic fatty pancreatic disease is associated with insulin resistance. •The triglyceride-glucose index has been used as a reliable marker for the diagnosis of insulin resistance. •The triglyceride-glucose index correlates positively with the degree of non-alcoholic fatty pancreatic disease. Background - Nonalcoholic fatty pancreatic disease (NAFPD) is an increase of fat in the pancreas, and has an important association with insulin resistance (IR) and type 2 diabetes mellitus. Research has confirmed that the triglyceridemia/glycemia (TyG) index determines IR as much as does the hyperinsulinemic-euglycemic clamp assessment as the homeostasis model testing of IR (HOMA-IR). Objective - To eva-luate the association between degree of NAFPD and TyG index. Methods - In 72 patients undergoing ultrasound of abdomen with a diagnosis of NAFPD, insulin, glucose, and triglycerides levels were evaluated. The HOMA-IR and TyG indexes were used as a reference for IR. The degrees of NAFPD and the TyG index were presented through the receiver operating characteristics (ROC) curves in order to evaluate the association between different degrees of NAFPD, and the correlation of NAFPD with HOMA-IR was also evaluated. Results - There was a statistically significant correlation between the degree of NAFPD and the TyG index. The AUROC curve for the TyG index for predicting the degree of NADPD was 0.855 (0.840-0.865). The intensity-adjusted probabilities of the degree of NAFPD were more strongly associated with TyG values when compared with HOMA-IR. Conclusion - In this study the TyG index correlated positively with the degree of NAFPD, performing better than HOMA-IR.
