Hepatitis C (HCV) liver biopsy analysis reveals distinct morphological changes in acute and chronic infections. These histopathological findings, including cell degeneration, necrosis, and inflammation, offer key diagnostic clues for identifying HCV.

Area of Science:

  • Hepatology
  • Virology
  • Pathology

Background:

  • Hepatitis C virus (HCV) infection is a significant global health concern.
  • Accurate diagnosis relies on serological and molecular methods, but liver biopsy remains crucial for staging and assessing disease severity.
  • Understanding the histopathological features of HCV is vital for patient management.

Purpose of the Study:

  • To investigate and characterize the morphological changes in liver biopsies of patients diagnosed with hepatitis C.
  • To correlate histopathological findings with clinical presentations of acute and chronic hepatitis C.
  • To identify diagnostic clues from liver biopsy in hepatitis C patients.

Main Methods:

  • Analysis of liver biopsies from 70 patients with a clinical diagnosis of hepatitis C.

  • Patients were confirmed positive for anti-HCV antibodies and/or HCV RNA.
  • Histopathological examination focused on cellular changes, inflammation, necrosis, and fibrosis in acute and chronic hepatitis C cases.

    • Main Results:

    • Acute hepatitis C showed focal liver cell degeneration, focal necrosis with T-lymphocyte infiltration, sinusoidal inflammation, and lymphoid aggregation with bile duct damage in 60% of cases.
    • Chronic active hepatitis (CAH) exhibited dense lymphoid aggregates in enlarged portal tracts, bridging necrosis and fibrosis, lobular inflammation, focal necrosis, fatty degeneration, and sinusoidal cell hyperplasia.
    • Seventeen cases of chronic persistent hepatitis (CPH) and 33 cases of CAH were identified.

    Conclusions:

    • Distinct morphological changes observed in liver biopsies can aid in the diagnosis of hepatitis C.
    • Histopathological patterns differ between acute and chronic hepatitis C, with CAH showing more severe changes like bridging fibrosis and lobular inflammation.
    • These findings underscore the importance of liver biopsy in the comprehensive evaluation of hepatitis C infection.
