Cell-mediated immunity in amoebic liver abscess.

B M Gandhi, H Gupta, M Irshad

    The Journal of Tropical Medicine and Hygiene
    |August 1, 1986
    PubMed
    Summary

    Amoebic liver abscess is linked to a temporary weakening of cell-mediated immunity, allowing parasite invasion. Treatment reverses this immunodepression, restoring the host

    Area of Science:

    • Immunology
    • Infectious Diseases
    • Hepatology

    Background:

    • Amoebic liver abscess (ALA) is a significant global health concern.
    • The role of cell-mediated immunity in ALA pathogenesis requires further elucidation.

    Purpose of the Study:

    • To investigate cell-mediated immunity in patients with amoebic liver abscess.
    • To assess immune status before and after treatment for ALA.

    Main Methods:

    • Leukocyte migration inhibition test (LMIT) was performed on 26 ALA cases.
    • T-cell counting was conducted in 23 ALA cases.
    • Tests were repeated post-treatment and compared with healthy controls and Entamoeba histolytica cyst passers.

    Main Results:

    • Patients with ALA exhibited a transient state of immunodepression.
    • This immune suppression may facilitate Entamoeba histolytica invasion.
    • Immune responses normalized after successful treatment and clinical recovery.

    Conclusions:

    • Cell-mediated immunity plays a crucial role in host defense against amoebic liver abscess.
    • Transient immunodepression is a key factor in ALA development.
    • Therapeutic interventions can restore immune function in ALA patients.
