ABSTRACT: Background and Objectives In the last few decades,Nonalcoholic Fatty Liver Disease (NAFLD) has become a common health issue that leads to serious complications like cirrhosis, cardiovascular disease, etc. Insulin resistance (IR) is the key pathogenic factor for NAFLD. The young medicos being habituated in stressful and sedentary lifestyle and representative of the youth as well can fully justify their selection as study population and help to build social awareness by emphasizing the importance of early lifestyle modifications in preventing or delaying the severe complications of NAFLD. This study is aiming to find out if there is any correlation of hepatic steatosis with IR, Alanine Transaminases (ALT), Aspartate Transaminases (AST) or Gama Glutamyl Transferases (GGT) and also to identify if one enzyme is better correlating with hepatic steatosis than others in the scenario of Insulin Resistance among young medicos. METHODS: 132 medical students of North Bengal Medical College, aged between 18-25 years were included in this institution based observational cross-sectional study. Their Fasting Insulin, glucose, ALT, AST, GGT were measured, and IR was calculated by the Homeostatic Assessment of Insulin Resistance (HOMA-IR) calculator. Sonography was done to assess Hepatic steatosis. RESULTS: Among 132 subjects normal, grade 1 and grade 2 fatty changes have been found in 67.4%, 25%, and 7.6% of the study population respectively. The Grouping was done using the cut-off value of IR (i.e. subjects with IR<1.525 vs. IR≥1.525). Significant differences were found in the mean values of ALT, AST, GGT between groups. Significant positive concordances were found between enzymes ALT, GGT, and hepatic steatosis in subjects having IR ≥ 1.525.Regression analysis showed that higher GGT values have a stronger positive correlation with hepatic steatosis than ALT among the same. Interpretation and Conclusion From this study, we can interpret that subjects having higher GGT values are better associated with steatosis than those having higher ALT values and can lead us to the conclusion that GGT might be an important independent marker for NAFLD associated with IR. Furthermore, such observations may suggest considering GGT as a marker for assessing the severity of fatty liver irrespective of etiopathogenesis, though the population-based vivid evaluation is highly recommended.
