Leukocyte lysosomal function in sepsis.

G Konn, H S Himal

    Surgery, Gynecology & Obstetrics

    Summary
    This summary is machine-generated.

    Postoperative infection risk may be indicated by changes in leukocyte lysosomal enzyme release and myeloperoxidase activity. These markers may decrease before infectious complications arise in surgical patients.

    Area of Science:

    • Biochemistry
    • Immunology
    • Surgical Pathology

    Background:

    • Elective operations carry a risk of postoperative infectious complications.
    • Leukocyte function, including lysosomal enzyme release and myeloperoxidase activity, is crucial for immune response.

    Purpose of the Study:

    • To investigate leukocyte lysosomal enzyme release, lysosome latency, and myeloperoxidase activity in patients undergoing elective surgery.
    • To determine if these leukocyte parameters correlate with the development of postoperative infectious complications.

    Main Methods:

    • Assessed leukocyte lysosomal enzyme release, lysosome latency, and myeloperoxidase activity.
    • Studied 117 patients undergoing elective operations and 17 control patients.
    • Monitored patients for infectious complications in the postoperative period.

    Main Results:

    • Fifteen patients developed postoperative infectious complications.
    • In these 15 patients, percentage lysosomal enzyme release and myeloperoxidase activity significantly decreased and remained low by the 7th postoperative day.
    • In four patients, these alterations preceded the clinical diagnosis of infectious complications.

    Conclusions:

    • Abnormal leukocyte lysosomal enzyme release and myeloperoxidase activity may serve as indicators for patients at risk of developing infectious complications after elective surgery.
    • These biochemical markers could play a role in the pathophysiology of postoperative infections.
