Cellular immunity in burns

A Y Sukhtankar, S R Sengupta

    Burns, Including Thermal Injury
    |January 1, 1982
    PubMed
    Summary
    This summary is machine-generated.

    Cellular immunity, including T-cell counts and macrophage migration inhibition factor (MIF) index, is suppressed in burn patients. Restoring these immune functions significantly enhances the body's bactericidal activity.

    Area of Science:

    • Immunology
    • Burn Medicine
    • Cellular Biology

    Background:

    • Cellular immunity plays a crucial role in the body's defense mechanisms.
    • Burn injuries significantly impair immune function, increasing susceptibility to infection.
    • Understanding these immune alterations is vital for effective burn patient management.

    Purpose of the Study:

    • To evaluate cellular immunity parameters in burn patients.
    • To assess the impact of these immune parameters on bactericidal activity.
    • To investigate the correlation between burn severity and immune response.

    Main Methods:

    • Measurement of T-cell count (per mm³ and percentage).
    • Assessment of blastoid transformation.
    • Quantification of macrophage migration inhibition factor (MIF) index.

  • Evaluation of the bactericidal index.

    • Main Results:

    • T-cell count was depressed in burn patients, correlating with burn severity.
    • Blastoid transformation and MIF index were significantly reduced, particularly in major burns (>25% TBSA).
    • Depressed cellular immunity parameters negatively impacted bactericidal index, while near-normal levels enhanced it.

    Conclusions:

    • Cellular immune functions, including T-cell count, blastoid transformation, and MIF, are compromised following burn injury.
    • These immune parameters significantly influence the bactericidal index, affecting infection control.
    • Restoration of cellular immunity towards normal limits is crucial for enhancing bactericidal activity in burn patients.
