Postoperative stress in neurosurgical patients significantly reduces T-helper (Th) cells, impacting antibody production and lowering resistance to infections and cancer. This immune system change highlights the severity of surgical stress.

Area of Science:

  • Immunology
  • Neurosurgery
  • Oncology

Background:

  • Neurosurgical procedures induce significant physiological stress.
  • Patient stress levels can impact immune function and clinical outcomes.
  • Understanding immune responses to surgical stress is crucial for patient management.

Purpose of the Study:

  • To evaluate the impact of neurosurgical stress on immune cell populations.
  • To assess changes in lymphocyte subpopulations, serum complement, and immune complexes.
  • To correlate immune changes with patient stress levels and potential health risks.

Main Methods:

  • Studied 31 neurosurgical patients with unaffected consciousness.
  • Compared pre- and postoperative peripheral blood lymphocyte populations (B, T, Th cells).

  • Measured serum complement and circulating immune complexes using established laboratory methods.

    • Main Results:

    • Observed a significant decrease in T-helper (Th) cells postoperatively.
    • Noted a consecutive diminution in antibody production.
    • Data suggest a link between reduced Th cells and lower resistance to infections and cancer.

    Conclusions:

    • Neurosurgical stress leads to a decline in Th cells, compromising immune surveillance.
    • Reduced antibody production is a key consequence of this immune modulation.
    • These findings underscore the importance of monitoring immune status in neurosurgical patients.
