[Immunologic and hematologic sequelae of splenectomy].

J Wybran

    Acta Chirurgica Belgica
    |May 1, 1983
    PubMed
    Summary

    Splenectomy in children can cause elevated platelets and increase infection risk, especially if done before age 6. Early intervention with antibiotics and immunizations can mitigate these severe consequences.

    Area of Science:

    • Pediatric Hematology
    • Pediatric Immunology
    • Surgical Consequences

    Context:

    • Splenectomy, the surgical removal of the spleen, is performed in children for various hematological and oncological conditions.
    • The spleen plays a crucial role in immune surveillance and hematological regulation.
    • Understanding the post-splenectomy sequelae is vital for managing pediatric patients.

    Purpose:

    • To summarize the hematological and immunological consequences of splenectomy in children.
    • To highlight the risks associated with early-life splenectomy.
    • To discuss potential therapeutic measures to mitigate adverse outcomes.

    Summary:

    • Hematological changes include persistent thrombocytosis (elevated platelet counts) and leukocytosis (elevated white blood cell counts).
    • Immunological impairment, particularly in children under 6-7 years old, leads to an increased susceptibility to overwhelming post-splenectomy infection (OPSI).
    • Mechanisms involve impaired antibody production and reduced clearance of encapsulated bacteria by the reticuloendothelial system.

    Impact:

    • Informs clinical practice regarding the timing and management of pediatric splenectomy.
    • Emphasizes the importance of prophylactic measures like vaccinations and antibiotic therapy.
    • Highlights the need for long-term monitoring of children who have undergone splenectomy.
