Hepatocyte growth factor and chronic hepatitis C

Area of Science:

• Hepatology
• Biochemistry
• Immunology

Background:

• Hepatocyte growth factor (HGF) is a cytokine involved in liver regeneration and fibrosis.
• Serum HGF levels can indicate liver damage and dysfunction in various liver diseases.
• Chronic hepatitis C (CHC) is a significant global health concern with complex disease progression.

Purpose of the Study:

• To investigate serum HGF levels in patients with CHC.
• To analyze the correlation between HGF and biochemical, histological, and virological parameters in CHC.
• To assess HGF's utility in monitoring treatment response in CHC.

Main Methods:

• Serum HGF concentration was measured using ELISA in 45 CHC patients.
• Correlations were analyzed between HGF levels and liver necroinflammatory/fibrosis scores, liver function tests, and viral load.
• HGF levels were also examined in a subgroup undergoing antiviral therapy.

Main Results:

• Serum HGF concentrations were significantly elevated in CHC patients compared to healthy controls.
• Higher HGF levels were associated with significant liver fibrosis (F ≥ 2), older age, lower platelet count, and elevated AST and GGT.
• Multivariate analysis identified HGF as an independent predictor of significant fibrosis, with performance comparable to existing non-invasive markers.

Conclusions:

• Serum HGF concentration is a valuable biomarker correlating with liver fibrosis severity in CHC patients.
• HGF levels are insensitive to therapeutic changes and cannot be used to monitor the effectiveness of antiviral therapy in CHC.
