M E Conley, C L Park, S D Douglas

    The Journal of Pediatrics
    |June 1, 1986
    PubMed
    Summary

    Childhood common variable immunodeficiency (CVID) in eight patients presented with autoimmune disease and severe infections. This distinct subset of CVID shows multisystemic disorder with significant morbidity and mortality.

    Area of Science:

    • Immunology
    • Pediatric Autoimmunity
    • Clinical Genetics

    Background:

    • Common variable immunodeficiency (CVID) is a primary immunodeficiency characterized by impaired antibody production.
    • Autoimmune diseases frequently occur in patients with CVID, but specific pediatric subsets require further definition.
    • Understanding these subsets is crucial for accurate diagnosis and management of complex pediatric cases.

    Purpose of the Study:

    • To describe the clinical and laboratory findings in a cohort of eight children with CVID and autoimmune disease.
    • To identify unique characteristics and manifestations of this specific pediatric CVID subset.
    • To highlight the association between CVID, autoimmunity, and severe infections in children.

    Main Methods:

    • Retrospective analysis of clinical data from eight pediatric patients diagnosed with CVID and autoimmune disease.
    • Review of laboratory findings, including immunophenotyping of T cells (T4/T8 ratio) and immunoglobulin levels.
    • Documentation of autoimmune manifestations, infection types, and clinical course.

    Main Results:

    • Six patients presented with early-onset symptoms including diarrhea or recurrent respiratory infections.
    • Autoimmune manifestations were diverse, including thrombocytopenia, hemolytic anemia, secretory diarrhea, arthritis, hepatitis, parotitis, and Guillain-Barré syndrome.
    • Laboratory findings revealed an elevated T4/T8 cell ratio due to decreased T8 cells, fluctuating immunoglobulin levels, and impaired B cell antibody production. Severe herpesvirus infections were noted alongside typical bacterial infections.

    Conclusions:

    • This group represents a distinct pediatric subset of hypogammaglobulinemia with CVID and multisystemic autoimmune disease.
    • The condition is characterized by significant morbidity, mortality, and a relapsing-remitting course dominated by autoimmune features.
    • Early identification and comprehensive management are essential for this complex pediatric disorder.
