Surgical trauma triggers both hyperinflammation and immunosuppression, impacting the immune system. Effective treatment requires balancing these opposing immune responses for better patient outcomes.

Area of Science:

  • Immunology
  • Surgical Pathology

Background:

  • Surgical trauma significantly impacts both specific and non-specific immune responses.
  • Evidence suggests a complex interplay between surgical stress and immune system modulation.

Purpose of the Study:

  • To review current knowledge on mechanisms of immune dysfunction post-surgical trauma.
  • To outline strategies for treating immune dysregulation following surgery.

Main Methods:

  • Literature review of experimental and clinical studies.
  • Analysis of immune response mechanisms and therapeutic approaches.

Main Results:

  • Major surgery causes early hyperinflammation (TNF-α, IL-1, IL-6, neutrophil activation) followed by immunosuppression (monocyte deactivation, Th2 shift).

  • This immune imbalance is driven by pro-inflammatory and anti-inflammatory mediators, including IL-6, PGE2, IL-10, and TGF-β.
  • Therapeutic strategies target restoring immune balance, such as using interferon-gamma (IFN-γ) or inhibiting prostaglandin E2 (PGE2).

    • Conclusions:

    • Post-surgery immune dysfunction involves both hyperinflammation and immunosuppression.
    • Therapeutic regimens should address both phases to restore immune homeostasis.
    • Balancing immune mediators and cells is crucial for effective treatment strategies.
