Major trauma and surgery can cause immunodeficiency, decreasing key immune cells and proteins. Further research is needed to identify predictive markers for infections and improve treatments beyond intravenous immunoglobulins.

Area of Science:

  • Immunology
  • Trauma Surgery

Background:

  • Post-trauma and post-surgery immunodeficiency syndromes are linked to frequent infections after severe injuries and major operations.
  • Understanding these syndromes is crucial for managing patient outcomes and preventing complications.

Purpose of the Study:

  • To investigate the immunological changes following polytrauma and major surgery.
  • To identify potential predictive parameters for infection risk in these patients.

Main Methods:

  • Analysis of immunoglobulin levels, complement factors (C3C, C4, C Factor B), and circulating immune cells (lymphocytes, CD3, CD4, CD8, NK cells).
  • Assessment of mononuclear cell function, including stimulatory capacity to mitogens and spontaneous thymidine uptake.
  • Correlation of immunological changes with surgery type and infection rates.

Main Results:

  • Significant decreases observed in immunoglobulins, complement factors, lymphocyte counts, and mononuclear cell stimulatory capacity.
  • Elevated levels of acute phase proteins, neopterin, interleukin-2 receptors, and increased spontaneous thymidine uptake by mononuclear cells.
  • The extent and duration of these immune alterations varied based on the type and extent of surgery.

Conclusions:

  • Polytrauma and major surgery induce complex immunodeficiency syndromes characterized by specific immunological shifts.
  • Current understanding of crucial factors and predictive markers for infection remains incomplete.
  • Further research is essential to develop targeted immunomodulatory strategies to complement existing treatments like intravenous immunoglobulins for infection prevention.
