Summary

Patients with biliary lithiasis, especially acute cholecystitis and icteric choledocholithiasis, exhibit impaired cell-mediated immunity. This anergy correlates with increased risk of postoperative septic complications.

Area of Science:

  • Immunology
  • Gastroenterology
  • Surgical Oncology

Background:

  • Biliary lithiasis, encompassing gallstones and bile duct stones, can impact immune function.
  • Assessing cell-mediated immunity preoperatively is crucial for predicting surgical outcomes.

Purpose of the Study:

  • To evaluate the preoperative cell-mediated immune response in patients with biliary lithiasis.
  • To identify factors associated with immune dysfunction in these patients.
  • To correlate immune status with the incidence of postoperative septic complications.

Main Methods:

  • A prospective study involving 428 subjects (212 controls, 216 patients) with biliary lithiasis.
  • Delayed hypersensitivity response assessed using the Multitest, classifying subjects as immunocompetent, relatively anergic, or anergic.

  • Analysis of potential causative factors including hemoglobin, hematocrit, and bilirubin levels.

    • Main Results:

    • Significant differences in immune response were observed between controls and patients with various forms of biliary lithiasis.
    • Acute cholecystitis and icteric choledocholithiasis showed high incidences of cell-mediated immune failure (71% and 82%, respectively).
    • Low hemoglobin/hematocrit levels were linked to anergy in acute cholecystitis; elevated bilirubin correlated with anergy in choledocholithiasis.

    Conclusions:

    • Patients with acute cholecystitis and icteric choledocholithiasis frequently exhibit impaired cell-mediated immunity.
    • Jaundice appears associated with immune failure in choledocholithiasis.
    • Anergic states strongly correlate with the development of postoperative septic complications, highlighting the need for immune assessment.
