[Liver fibrosis : clinics, diagnostics and management]

Area of Science:

• Hepatology
• Pathology
• Biochemistry

Context:

• Liver fibrosis stems from chronic liver damage, leading to parenchymal scarring.
• It complicates all chronic liver diseases, with 20-40% progressing to cirrhosis.
• Clinical presentation is often nonspecific, with diagnosis frequently incidental via elevated liver enzymes.

Purpose:

• To review the current understanding and diagnostic approaches to liver fibrosis.
• To discuss therapeutic strategies for managing liver fibrosis and its progression.
• To highlight the ongoing research into novel, non-specific interventions for fibrosis regression.

Summary:

• Liver fibrosis is characterized by liver scarring due to chronic damage, progressing to cirrhosis in a significant portion of cases.
• Diagnosis often relies on elevated liver enzymes, with liver biopsy as the gold standard, though non-invasive markers are emerging.
• Current treatments focus on etiology-specific therapies, but research is exploring non-specific interventions for fibrosis regression based on molecular fibrogenesis pathways.

Impact:

• Improved understanding of liver fibrosis diagnosis and progression.
• Potential for earlier detection and intervention in chronic liver diseases.
• Advancement of novel therapeutic strategies targeting fibrosis regression beyond etiology-specific treatments.
