    Splenectomy may increase autoantibodies, particularly antiheart antibodies, in some patients. This suggests spleen removal might disrupt immune regulation, potentially linked to reduced suppressor T cells.

    Area of Science:

    • Immunology
    • Surgical Pathology

    Background:

    • The spleen plays a crucial role in immune system regulation.
    • Splenectomy, the surgical removal of the spleen, can have implications for immune function.
    • Autoantibodies are indicative of immune system dysregulation.

    Purpose of the Study:

    • To investigate the prevalence of autoantibodies in splenectomized individuals.
    • To explore potential correlations between splenectomy and autoantibody formation.
    • To assess the impact of splenectomy on immune regulatory processes.

    Main Methods:

    • Sera from 41 splenectomized subjects were analyzed.
    • The indirect immunofluorescence method was used to detect autoantibodies.
    • Splenectomy reasons (trauma vs. elective) and patient age were considered.

    Main Results:

    • 26% of subjects (11 out of 41) showed one or more autoantibodies.
    • Antiheart antibodies were the most frequently detected autoantibody type.
    • Higher antibody incidence was observed in splenectomy for trauma versus elective procedures.
    • Positive autoantibody results were more common in individuals splenectomized at a younger age.

    Conclusions:

    • Splenectomy may lead to the presence of autoantibodies in a significant portion of individuals.
    • The findings suggest a potential disturbance in immune regulatory mechanisms post-splenectomy.
    • Reduced suppressor T cells, due to the spleen being a major pool, are postulated as a contributing factor.
