Non-alcoholic fatty liver disease

Area of Science:

• Hepatology
• Metabolic Diseases
• Pathophysiology

Background:

• Non-alcoholic fatty liver disease (NAFLD) prevalence is rising globally, mirroring obesity rates.
• NAFLD is linked to insulin resistance and metabolic syndrome, with some cases progressing to non-alcoholic steatohepatitis (NASH).
• NASH, a severe form of NAFLD, involves liver damage, inflammation, and fibrosis, posing a significant health concern.

Purpose of the Study:

• To review the mechanisms of hepatic insulin resistance in NAFLD/NASH.
• To examine the factors determining fibrosis progression in NASH within the metabolic syndrome context.

Main Methods:

• Literature review focusing on NAFLD/NASH pathogenesis.
• Analysis of studies investigating insulin resistance in the liver.
• Examination of research on fibrotic processes in NASH.

Main Results:

• Hepatic insulin resistance is a key feature of NAFLD and NASH.
• Metabolic syndrome components significantly influence the development and progression of liver fibrosis.
• Understanding these mechanisms is crucial for identifying at-risk patients and developing therapies.

Conclusions:

• Hepatic insulin resistance and fibrosis determinants are critical areas for NAFLD/NASH research.
• Further investigation is needed to identify patients at risk and to develop effective treatments for NASH.
• Targeting metabolic pathways may offer therapeutic strategies for managing NASH progression.
