ABSTRACT
Non-alcoholic fatty liver disease (NAFLD) has emerged as one of the lethal causes of chronic liver disease globally. NAFLD can ultimately progress to non-alcoholic steatohepatitis (NASH) given persistent cellular insult. The crux of the problem lies in fat accumulation in the liver, such as increased fatty acid substrates owing to consumption of a high-fat diet, altered gut physiology, and excess adipose tissue. Being the hepatic manifestation of metabolic syndrome, insulin resistance is also among one of the many stimuli. Therefore, drugs, such as glucagon-like peptide-1 receptor agonist (GLP-1 RA) can play a significant role in reducing inflammation, in addition to weight loss and dietary habits. In this review article, we have reviewed the role of exenatide, liraglutide, and semaglutide in the management of NASH. Two of the agents, exenatide and semaglutide, have a predominant role in reducing alanine aminotransferase (ALT) levels, therefore reducing inflammation and promoting weight loss. However, these agents have a lesser impact on the degree of fibrosis. Liraglutide, on the other hand, has been shown to significantly decrease the degree of fibrosis and has been found helpful in reversing mild degrees of steatosis. Therefore, these agents warrant attention to the new perspective that has been presented so that future guidelines may incorporate and streamline individualized therapy.
