[T-rosette test in Wilson's disease].

    Summary
    This summary is machine-generated.

    Patients with Wilson's disease exhibit impaired T-lymphocyte function, indicated by lower T-cell counts and reduced delayed hypersensitivity responses. This immune dysfunction may explain B-lymphocyte hyperactivity in Wilson's disease.

    Area of Science:

    • Immunology
    • Hepatology
    • Genetics

    Background:

    • Wilson's disease is a genetic disorder of copper metabolism.
    • Immune system dysregulation is suspected in Wilson's disease pathogenesis.
    • T-lymphocyte function in Wilson's disease requires further investigation.

    Purpose of the Study:

    • To evaluate T-lymphocyte counts and function in patients with Wilson's disease.
    • To assess delayed hypersensitivity responses in Wilson's disease patients.
    • To explore the link between T-lymphocyte abnormalities and B-lymphocyte hyperactivity.

    Main Methods:

    • Rosette formation test for T-lymphocyte quantification.
    • Skin tests using Candida albicans antigen for delayed hypersensitivity.
    • Dinitrochlorobenzene (DNCB) immunization for sensitization assessment.

    Main Results:

    • Significantly lower T-lymphocyte counts in Wilson's disease patients compared to controls.
    • Reduced frequency of positive delayed hypersensitivity reactions to Candida albicans.
    • Lower incidence of positive DNCB immunization reactions in patients.

    Conclusions:

    • T-lymphocyte functions are disturbed in Wilson's disease.
    • Impaired T-cell mediated immunity is a feature of Wilson's disease.
    • This T-lymphocyte dysfunction may contribute to B-lymphocyte hyperactivity.
