Background:The liver is the major metabolic organ which plays vital role in maintaining glucose homeostasis. Aberrant liver metabolism leads to non-alcoholic fatty liver disease (NAFLD).It adversely builds up insulin resistance, dyslipidaemia, and is probably the most common cause of derangement of liver enzymes and lipid profile in type 2 diabetes mellitus (T2DM).The current study was undertaken to explore the relationship between liver enzymes and lipid profile in pre-diabetes and T2DM. Materials and methods: A total of 618 subjects (203-control, 206-Prediabetes and 209-type 2 diabetes mellitus) were enrolled in this cross-sectional study. Blood pressure and anthropometric indices like height, weight, Body mass index and waist circumference were measured in all subjects. Biochemical parameters like fasting plasma glucose, HbA1c, Lipid profile, liver enzymes-AST, ALT, ALP and GGT were estimated in all the study subjects. Results: In both males and females, the mean levels of BMI, WC, SBP, HbA1c, FPG, GGT, TGL and VLDL showed significant p Value. In Pre-diabetes, both GGT and ALT showed significant positive correlation with TC, TGL, LDL-C and VLDL-C. HDL-C showed negative correlation with ALT. In T2DM, ALT showed significant positive correlation with total cholesterol and LDL-C. GGT showed significant positive correlation with TC, TGL, LDL-C and VLDL-C.
Conclusion:By looking at the level of routine blood parameters like Liver enzymes and lipid profile in impaired glycaemia patients, it is possible to assess the extent of liver damage and also the risk of cardiovascular accident .Thereby development of type 2 diabetes mellitus can be prevented at an early stage itself..
