IgE in respiratory tract allergies

G Mogi, S Maeda, T Yoshida

    Transactions. Section on Otolaryngology. American Academy of Ophthalmology and Otolaryngology
    |March 1, 1977

    Summary

    This study found elevated immunoglobulin E (IgE) in allergic patients. Nasal IgE levels correlate more closely with respiratory allergy pathogenesis than serum IgE, though diagnostic value is currently limited.

    Area of Science:

    • Immunology
    • Allergy Research

    Background:

    • Elevated immunoglobulin E (IgE) is a hallmark of allergic diseases.
    • Assessing IgE in both serum and respiratory secretions is crucial for understanding allergic responses.

    Purpose of the Study:

    • To investigate the role of IgE and specific IgE antibodies in nasal allergy and bronchial asthma.
    • To compare the diagnostic utility of IgE in serum versus nasal secretions for respiratory allergies.

    Main Methods:

    • Quantified total IgE in serum and nasal secretions using Phadebas IgE kits.
    • Performed radioallergosorbent test (RAST) to measure specific IgE antibodies to mites.
    • Correlated IgE levels and specific IgE activity with skin test results (HD and mite tests).

    Main Results:

    • Significantly elevated IgE levels were observed in both serum and nasal secretions of allergic patients.
    • Specific IgE antibody activity to mites correlated significantly with skin test results.
    • IgE in nasal secretions showed a stronger association with respiratory allergy pathogenesis than serum IgE.

    Conclusions:

    • Determination of IgE and specific IgE antibodies is valuable for diagnosing and studying respiratory tract allergies.
    • Nasal IgE is more relevant to allergy pathogenesis than serum IgE, but diagnostic limitations exist due to concentration issues.
