[Cellular immunity in pollinosis patients].

    Summary

    Seasonal pollinosis (hay fever) in 107 patients showed reduced T-lymphocytes and increased B-cells, indicating a weakened immune response. These immunological changes suggest a secondary immune deficiency in hay fever patients during peak pollen seasons.

    Area of Science:

    • Immunology
    • Allergy Research

    Background:

    • Pollinosis, commonly known as hay fever, is an allergic reaction affecting numerous individuals during specific seasons.
    • Understanding the immunological underpinnings of pollinosis exacerbations is crucial for developing targeted therapies.

    Purpose of the Study:

    • To investigate the specific immunological alterations in patients experiencing seasonal pollinosis exacerbations.
    • To characterize changes in lymphocyte populations and their functional markers during the spring-summer allergy season.

    Main Methods:

    • Analysis of lymphocyte subsets, including T-lymphocytes and B-lymphocytes, in 107 patients with seasonal pollinosis.
    • Assessment of lymphocyte activity markers, such as "active" lymphocytes, theophyllin-sensitive lymphocytes, and histamin-sensitive cells.
    • Evaluation of B-cell differentiation status and autorosette-forming lymphocyte counts.

    Main Results:

    • Patients exhibited T-lymphopenia (reduced T-lymphocytes) and an increased number of 0-lymphocytes.
    • A reduction in "active" and theophyllin-sensitive lymphocytes, as well as histamin-sensitive cells, was observed.
    • The study noted an increase in low-differentiated B-cells and a decrease in autorosette-forming lymphocytes.

    Conclusions:

    • The observed immunological shifts in pollinosis patients suggest a state of secondary immunological insufficiency.
    • The specific pattern of immune changes aligns with a relative hyposuppressor variant of immune deficiency.
    • These findings highlight the complex immune dysregulation occurring during seasonal allergic exacerbations.
