    Summary

    Phospholipid-based hepatoprotectors combined with prednisolone mitigate immune suppression in rats with toxic hepatitis. This combination counters thymus atrophy and enhances immune cell activity, offering a potential therapeutic strategy.

    Area of Science:

    • Toxicology
    • Immunology
    • Pharmacology

    Background:

    • Toxic hepatitis, induced by tetrachloromethane, causes significant immune system impairment.
    • Glucocorticoids like prednisolone, while effective, can have immunosuppressive side effects.

    Purpose of the Study:

    • To investigate the effects of phospholipid-containing hepatoprotectors (eplir and essentiale) in combination with prednisolone on the immune system in a rat model of toxic hepatitis.

    Main Methods:

    • Induction of toxic hepatitis in rats using tetrachloromethane.
    • Administration of phospholipid hepatoprotectors (eplir, essentiale) concurrently with prednisolone.
    • Assessment of immune parameters including thymus atrophy, blood lymphocyte counts, splenic blastogenesis, and mononuclear cell receptor activity (C3b, Fc(gamma)).

    Main Results:

    • The combination therapy significantly decreased the immunosuppressive effects of prednisolone.
    • Observed improvements included reduced thymus atrophy and increased numbers of blood lymphocytes and splenic blasts.
    • Enhanced functional activity of mononuclear cells was noted, indicated by increased C3b and Fc(gamma) receptor expression.

    Conclusions:

    • Hepatoprotectors containing phospholipids can counteract the immunosuppressive effects of prednisolone in toxic hepatitis.
    • This combination therapy may offer a beneficial approach to managing immune function during liver injury treatment.
