[Immunological abnormalities in atopic dermatitis (author's transl)].

J J Guilhou, J Meynadier, J Clot

    La Nouvelle Presse Medicale
    |October 1, 1979
    PubMed
    Summary

    Atopic dermatitis (AD) involves elevated immunoglobulin E (IgE), but its role is unclear. Research suggests potential causes include transient IgA deficiency or T cell defects, impacting cell-mediated immunity in AD patients.

    Area of Science:

    • Immunology
    • Dermatology
    • Allergy Research

    Context:

    • Atopic dermatitis (AD) is characterized by humoral immunological abnormalities, primarily elevated immunoglobulin E (IgE).
    • Elevated IgE levels in AD are inconsistent, non-specific, and their pathogenic role remains unclear.
    • Potential origins for IgE overproduction include transient neonatal immunoglobulin A (IgA) deficiency or impaired T cell regulation.

    Purpose:

    • To explore the immunological abnormalities in atopic dermatitis.
    • To investigate the potential origins of elevated IgE and defects in cell-mediated immunity in AD.
    • To discuss the correlation of these abnormalities with existing theories and their implications for treatment.

    Summary:

    • Humoral immune responses in AD show elevated IgE, though inconsistently and non-specifically.
    • Cell-mediated immunity defects, evidenced by reduced E rosettes and mitogen response, suggest a possible T suppressor cell dysfunction.
    • The study discusses the link between these immunological findings, Sczentivanyi's theory, and the role of immunopharmacological disturbances in AD.

    Impact:

    • Provides insights into the complex immunological underpinnings of atopic dermatitis.
    • Highlights potential diagnostic and therapeutic targets related to IgE regulation and T cell function.
    • Contributes to understanding the pathogenesis of AD and informs future research directions.
