Association Between the Triglyceride-Glucose Index and Serum Uric Acid to High-Density Lipoprotein (HDL) Cholesterol Ratio in Type 2 Diabetes Mellitus in Gabes City, Tunisia.

Background Type 2 diabetes mellitus (T2DM) is a significant risk factor for cardiovascular diseases (CVD). The triglyceride-glucose index (TyGi) is a novel biomarker for insulin resistance, strongly linked to CVD. Elevated serum uric acid levels and the uric acid to high-density lipoprotein cholesterol ratio (UHR) are emerging as markers of metabolic syndrome and cardiovascular risk in T2DM. This study aimed to explore the association between the TyGi and UHR in T2DM patients. Objectives The aim of this study is to compare metabolic parameters in T2DM patients and assess the association between the TyGi and serum UHR. Methodology A cross-sectional case-control study was conducted at the University Hospital of Gabes, Gabes City, Tunisia with 50 T2DM patients and 50 gender-matched healthy controls. Inclusion criteria included adults aged 30-75 years with a confirmed diagnosis of T2DM on stable medication for at least three months. Exclusion criteria included other types of diabetes, significant liver or kidney disease, recent cardiovascular events, endocrine disorders, and substance abuse. Metabolic and biochemical parameters, including fasting blood sugar, postprandial blood sugar, glycosylated hemoglobin, lipid profile, and renal function, were measured. The TyGi and serum UHR were calculated and analyzed for correlations. Results T2DM patients exhibited significantly higher fasting blood sugar, postprandial blood sugar, glycosylated hemoglobin, TyGi, and serum UHR compared to controls, indicating impaired glycemic control and adverse lipid profiles. The UHR showed a positive correlation with a strong negative correlation with HDL and a positive correlation with uric acid levels. The linear regression analysis indicated a weak positive trend between the TyGi and serum UHR, although not statistically significant. Conclusion This study underscores the importance of the TyGi and serum UHR as biomarkers for evaluating metabolic and cardiovascular risk in T2DM. Further research is needed to explore their combined utility in clinical practice for early detection and management of cardiovascular complications in diabetic patients.
