    Natural killer cell activity significantly decreases in severe liver diseases like hepatic coma and chronic active hepatitis. This finding suggests monitoring NK cell function could aid in predicting outcomes and developing immunotherapies for viral hepatitis.

    Area of Science:

    • Immunology
    • Hepatology
    • Virology

    Background:

    • Viral hepatitis, including types A and B, poses a significant global health burden.
    • Liver diseases can profoundly impact immune system function.
    • Natural killer (NK) cells play a crucial role in antiviral immunity.

    Purpose of the Study:

    • To investigate the functional activity of natural killer (NK) cells in patients with various liver diseases.
    • To compare NK cell activity across different stages and types of viral hepatitis.
    • To explore the potential of NK cell activity as a prognostic marker and therapeutic target.

    Main Methods:

    • Assessed the functional activity of normal killer (NK) cells in patient cohorts.
    • Included patients with acute viral hepatitis A, acute viral hepatitis B (including hepatic coma), and chronic liver diseases (persisting and active).

  • Utilized a control group of healthy subjects for comparison.

    • Main Results:

    • A marked decrease in NK cell activity was observed in patients with hepatic coma.
    • Significantly reduced NK cell activity was also found in patients with chronic active hepatitis.
    • NK cell activity levels varied across different forms of viral hepatitis.

    Conclusions:

    • The level of NK cell activity is a potential indicator for predicting both short-term and long-term outcomes of viral hepatitis.
    • Monitoring NK cell activity may inform the development of novel immunocorrecting therapies for liver diseases.
    • NK cell function assessment is valuable in managing patients with viral hepatitis.
