Serum protein changes after surgery mimic trauma but differ in detail. Acute-phase reactant proteins (APRPs) increase post-surgery, with higher levels indicating complications, particularly sepsis.

Area of Science:

  • Biochemistry
  • Surgical Medicine
  • Immunology

Background:

  • Surgery induces physiological stress, leading to changes in serum protein concentrations.
  • These protein changes are comparable to those seen after injury or trauma.
  • The detailed patterns of protein alteration can vary based on surgical outcomes.

Purpose of the Study:

  • To investigate alterations in 11 serum proteins post-surgery.
  • To differentiate protein change patterns between uncomplicated and complicated recovery.
  • To identify key proteins and factors influencing these changes.

Main Methods:

  • Monitoring concentrations of 11 serum proteins in surgical patients.
  • Comparing protein profiles in patients with and without surgical complications.

  • Analyzing the impact of sepsis on acute-phase reactant protein (APRP) levels.

    • Main Results:

    • Five APRPs showed marked increases, peaking 2 days post-surgery in uncomplicated cases.
    • Significant differences in APRP patterns were observed between complicated and uncomplicated recovery groups.
    • Alpha-1 antichymotrypsin (ACT) and C-reactive protein were notably higher in patients with complications, with ACT showing the clearest distinction.
    • Sepsis emerged as a primary driver of APRP changes during recovery.
    • Preoperative APRP levels did not predict complication risk.

    Conclusions:

    • Post-surgical serum protein profiles, particularly APRPs, can indicate recovery status.
    • Elevated ACT concentrations are a strong indicator of surgical complications.
    • The development of sepsis significantly influences APRP dynamics.
    • Inflamed tissue localization may affect APRP behavior during recovery.
