Association of Liver Aminotransferases with Lipid Profile in Patients with Type II Diabetes Mellitus

Reduced insulin secretion in Type II Diabetes Mellitus (T2DM) results in fat accumulation in hepatocytes and increase in liver enzymes. The hepatocyte destruction due to non-alcoholic fatty liver is associated with increased risk of cardiovascular diseases. Therefore, the aim of this study is to evaluate the association of liver transaminases with lipid profile in T2DM patients compared to healthy subjects.

A total of 1000 subjects (500 males and females with T2DM and 500 healthy subjects) participated in this case-control study. Diagnosis of T2DM was made based on the World Health Organization (WHO) criteria. Fasting blood samples (5 ml) were obtained from all subjects in the morning and the serum was extracted for the assessment of biochemical parameters was used to compare parameters between healthy and T2DM patients. Data were analyzed by SPSS version 20 and using Mann-Whitney test and Spearman correlation coefficient.

The serum total cholesterol (TCH), triglyceride, Alanine Aminotransferase (ALT), Aspartate Transaminase (AST), TCH/high density lipoprotein (HDL-C) ratio and atherogenecity index plasma were significantly higher in T2DM group compared to healthy individuals (p≤0.006). Among the lipid profile parameters only Risk ratio (TCH/HDL-C) was positively correlated with ALT (p=0.037) while no significant correlation was observed for other variables (P>0.05)

T2DM Patients have higher lipid profile, atherogenecity index and liver enzymes compared to healthy individuals. Furthermore, TCH/HDL-C was significantly correlated with ALT.
