Diagnosing chronic viral hepatitis requires indirect markers of immune response, not just virus detection. Monitoring viral load and immune markers helps determine treatment timing for better patient outcomes.

Area of Science:

  • Hepatology
  • Immunology
  • Virology

Background:

  • Specific etiological diagnosis of chronic viral hepatitis is challenging.
  • Directly identifying cytotoxic T lymphocytes is not feasible for routine diagnosis.
  • Virus markers alone do not confirm hepatitis-induced liver damage.

Purpose of the Study:

  • To identify reliable surrogate markers for diagnosing chronic viral hepatitis.
  • To explore the utility of indirect markers of host antiviral immune response.
  • To establish optimal methods for monitoring patients and initiating antiviral treatment.

Main Methods:

  • Analyzing kinetics of viral load (viraemia) and liver enzymes (aminotransferases).
  • Investigating IgM antibodies against viral antigens as potential diagnostic markers.

  • Utilizing quantitative and dynamic analyses of hepatitis virus markers.

    • Main Results:

    • Indirect markers, such as IgM antibodies, are needed to confirm viral hepatitis diagnosis.
    • Rapid changes in viraemia and aminotransferases reflect disease dynamics.
    • Liver histology changes are slower compared to viral and immune markers.

    Conclusions:

    • Indirect markers of antiviral immune response are crucial for accurate viral hepatitis diagnosis.
    • Kinetic analysis of variable parameters (viraemia, immune response) is key to understanding liver cell necrosis.
    • Quantitative and dynamic monitoring of hepatitis virus markers is essential for patient management and treatment timing.
