Abnormalities of lung function in hay fever

E J Morgan, D R Hall

    Thorax
    |February 1, 1976
    PubMed
    Summary

    Hay fever sufferers may have reversible small airway issues. Measuring dynamic compliance at different breathing rates effectively detects these lung function abnormalities when symptoms are active.

    Area of Science:

    • Pulmonary Medicine
    • Allergy and Immunology

    Background:

    • Hay fever (allergic rhinitis) affects many individuals.
    • Small airway dysfunction can be a subtle complication of respiratory conditions.

    Purpose of the Study:

    • To investigate potential small airway abnormalities in subjects with hay fever symptoms.
    • To assess the utility of various pulmonary function tests in detecting these abnormalities.

    Main Methods:

    • Studied 20 subjects with hay fever symptoms.
    • Performed pulmonary function tests including dynamic compliance, closing capacity, residual volume, transfer factor, and maximal expiratory flow-volume curves.
    • Repeated tests during winter when symptoms resolved.

    Main Results:

    • Frequency dependence of compliance, indicating small airway issues, was observed in 40% of symptomatic subjects.
    • Conventional pulmonary function tests remained within normal limits for all subjects.
    • Small airway abnormalities detected by frequency dependence of compliance resolved when hay fever symptoms subsided.

    Conclusions:

    • Reversible small airway abnormalities are common in subjects experiencing hay fever symptoms.
    • Dynamic compliance measurement at varying respiratory frequencies is a sensitive method for detecting these abnormalities.
    • These findings highlight the importance of assessing small airway function in allergic rhinitis management.
