Immunological evaluation of children undergoing tonsillectomy.

D Gogoi, O P Gupta, M K Agarwal

    The Journal of Otolaryngology
    |December 1, 1979
    PubMed
    Summary

    Tonsillectomy for chronic tonsillitis did not alter serum immunoglobulin levels (IgG, IgA, IgM). However, it normalized lymphocyte counts and improved cell-mediated immunity, indicating a positive impact on immune response.

    Area of Science:

    • Immunology
    • Otolaryngology
    • Cellular Biology

    Background:

    • Chronic tonsillitis is a common condition requiring surgical intervention.
    • The immunological consequences of tonsillectomy are not fully understood.
    • Evaluating immune status pre- and post-tonsillectomy is crucial for understanding its impact.

    Purpose of the Study:

    • To investigate the immunological changes following tonsillectomy in patients with chronic tonsillitis.
    • To assess serum immunoglobulin levels and cell-mediated immune responses before and after surgery.

    Main Methods:

    • Study included 80 patients undergoing tonsillectomy and 20 healthy controls.
    • Serum IgG, IgA, and IgM levels were measured.
    • Peripheral absolute lymphocyte count was assessed.

  • Skin tests using recall antigens (PPD, Candida) and a contact sensitizing agent (2:4 DNCB) were performed.

    • Main Results:

    • No significant changes were observed in serum IgG, IgA, and IgM levels post-tonsillectomy.
    • Peripheral absolute lymphocyte count was elevated pre-operatively compared to controls, normalizing after surgery.
    • Cell-mediated immune response, assessed via skin tests, showed improvement following tonsillectomy.

    Conclusions:

    • Tonsillectomy does not significantly affect humoral immunity as measured by serum immunoglobulins.
    • Tonsillectomy appears to modulate the immune system by normalizing lymphocyte counts and enhancing cell-mediated immunity.
