Comparative assessment of the HSI in patients with gastroenterological pathology and metabolic syndrome with overweight and obesity: molecular mechanisms, clinical validation, and pathophysiological correlations
GASTROENTEROLOGY AND DIETOLOGY
Abstract
The article presents a comparative assessment of the Hepatic Steatosis Index (HSI) in patients with gastrointestinal pathology and metabolic syndrome. The molecular mechanisms linking the increase in body mass index to steatosis progression are analyzed, including insulin resistance, lipotoxicity, and dysfunction of the gut-liver axis. Special attention is paid to the validation of HSI as a non-invasive biomarker reflecting hepatocyte metabolic health. It is demonstrated that the index effectively stratifies risks and correlates with systemic inflammation markers, serving as an accessible and pathogenetically substantiated screening tool for metabolic-associated steatotic liver disease in clinical practice.
