Association of aspartate and alanine transaminases with dyslipidemia in newly diagnosed and long duration of type 2 diabetes mellitus subjects.

Abstract

Objective: Association between alanine transaminase (ALT) and aspartate transaminase (AST) with newly diagnosed and known type 2 diabetes mellitus (DM) and to estimate association of liver enzymes with lipid profile in type 2 DM subjects. Study Design: Prospective Clinical study. Setting: Karachi University with Collaboration of Baqai Institute of Diabetology and Endocrinology. Period: November 2018 to May 2019. Material & Methods: Total 100 people were divided into four groups; Group I: 25 healthy controls with normal glucose tolerance, Group II: 25 newly diagnosed DM, Group III: 25 known DM type 2 with <5years duration and Group IV: 25 known DM type 2 between 5-10 years duration. Baseline data was collected on predesigned questionnaire. Blood samples for biochemical parameters were analyzed using standardized laboratory techniques. Results: Group I mean age (years) was 50.78±2.34, group II 50.56±1.96, group III 50.37±1.46 and group IV 56±1.36. In Group I, ALT and AST were significantly correlated to each other’s. In group II, ALT was significantly correlated with AST, triglycerides and HDL-C, while AST correlated with ALT and HDL-C. In group III, ALT was significantly correlated with AST, while AST correlated to ALT, triglycerides and HbA1c. However, in group IV, ALT was significantly correlated with AST, LDL-C and HDL-C, and, AST with ALT, total cholesterol, LDL-C and HDL-C. Conclusion: Elevated ALT and AST- the salient markers for disease of non-alcoholic fatty liver with deranged dyslipidemia were found in known type 2 DM as well as in newly diagnosed type 2 DM subjects.
