Serum complement C4 in chronic hepatitis C: correlation with histopathologic findings and disease activity

Area of Science:

• Hepatology
• Immunology
• Virology

Background:

• Chronic hepatitis C (HCV) can lead to severe liver conditions like cirrhosis and cancer.
• Current diagnostic markers for HCV often lack correlation with disease severity and liver histology.
• There is a need for reliable tests to assess HCV disease activity and correlate with liver biopsy findings.

Purpose of the Study:

• To investigate the relationship between serum complement levels and liver biopsy findings in patients with chronic hepatitis C.
• To determine if complement C3c and C4 levels can serve as indicators of disease activity in HCV.

Main Methods:

• A study included 70 chronic hepatitis C patients and 30 healthy controls.
• Patients were categorized based on transaminase levels; those with high levels underwent liver biopsy.
• Serum complement C3c and C4 levels were analyzed against biopsy results and other clinical data.

Main Results:

• Serum complement C3c and C4 levels were significantly lower in patients with high transaminases.
• Complement C4 levels showed a significant correlation with alanine aminotransferase and histological activity index.
• No correlation was found between complement C4 levels and liver fibrosis, or C3c levels with histological markers.

Conclusions:

• Serum complement C4 levels are associated with the histological activity index in chronic hepatitis C.
• Complement C4 may serve as a potential biomarker for assessing liver disease activity in HCV patients.
