In chronic hepatitis B, a decrease in total T lymphocytes was observed in HBsAg-positive patients. Active T lymphocytes increased in healthy individuals with a history of hepatitis B.

Area of Science:

  • Immunology
  • Hepatology
  • Virology

Background:

  • Chronic hepatitis B (CHB) is a significant global health concern.
  • Understanding immune responses in CHB is crucial for treatment and prognosis.
  • Hepatitis B surface antigen (HBsAg) serostatus is a key indicator in hepatitis B infection.

Purpose of the Study:

  • To investigate lymphocyte subpopulations and immune markers in chronic hepatitis patients.
  • To compare immune profiles between chronic active hepatitis (CAH), chronic persistent hepatitis (CPH), and healthy individuals with past acute hepatitis B.

Main Methods:

  • Analysis of lymphocyte subpopulations (T lymphocytes, B lymphocytes) and leukocyte migration inhibition.
  • Measurement of serum HBsAg and immunoglobulins (IgG, IgA, IgM).

  • Clinical, biochemical, and histological diagnosis of hepatitis B patients.

    • Main Results:

    • A reduced count of total T lymphocytes was found in HBsAg-seropositive chronic hepatitis patients.
    • An elevated number of active T lymphocytes was observed in HBsAg-seronegative healthy individuals with a history of acute viral hepatitis B.

    Conclusions:

    • Immune dysregulation, specifically T-lymphocyte alterations, is implicated in chronic hepatitis B pathogenesis.
    • Distinct T-lymphocyte profiles may differentiate disease states and recovery in hepatitis B infection.
