[Permanent decrease in immune function in patients with splenectomy for trauma].

M Kukoc, A Sapunar, V Vidjak

    Acta Chirurgica Iugoslavica
    |January 1, 1989
    PubMed
    Summary

    Splenectomy for trauma alters immune responses, decreasing IgM and total complement CH50 while increasing IgA and IgG. These changes in lymphocyte populations may explain the higher sepsis risk in splenectomized patients.

    Area of Science:

    • Immunology
    • Hematology

    Context:

    • Splenectomy is a surgical procedure to remove the spleen, often performed due to trauma.
    • Post-splenectomy immune function alterations are a significant concern, particularly regarding infection risk.

    Purpose:

    • To analyze peripheral blood immune markers in trauma patients following splenectomy.
    • To compare immunoglobulin levels, complement CH50, and T/B lymphocyte populations with a control group.

    Summary:

    • Splenectomized patients showed significantly decreased IgM and total complement CH50 levels (p<0.01).
    • Conversely, IgA and IgG levels were significantly increased (p<0.001 for IgA, p<0.01 for IgG).
    • T and B lymphocyte counts were altered, with a higher total lymphocyte count in splenectomized individuals compared to controls.

    Impact:

    • The study reveals persistent immune dysregulation after splenectomy for trauma.
    • These immune changes provide a potential explanation for the increased susceptibility to sepsis in this patient cohort.
