Asthma from plexiglas powders

B Kennes, P Garcia-Herreros, P Dierckx

    Clinical Allergy
    |January 1, 1981

    Summary
    This summary is machine-generated.

    A patient developed severe asthma from inhaling plexiglas dust at work. Specific inhalation challenges confirmed plexiglas as the trigger, leading to obstructive responses and improvement upon reduced exposure.

    Area of Science:

    • Occupational Medicine
    • Pulmonology
    • Toxicology

    Background:

    • Occupational asthma is a significant cause of respiratory morbidity.
    • Identifying specific workplace allergens is crucial for effective management.
    • Plexiglas (polymethyl methacrylate) is widely used in various industries.

    Observation:

    • A patient presented with severe asthma symptoms.
    • Workplace exposure to industrial products was investigated.
    • Specific inhalation challenge testing was performed.

    Findings:

    • The patient exhibited a specific and reproducible asthmatic reaction solely to plexiglas dust.
    • Pulmonary investigations ruled out alveolitis.
    • An immediate and a late obstructive respiratory response was observed post-challenge.

  • The patient was not atopic and lacked a history suggestive of chronic occupational disease.

    • Implications:

    • Plexiglas dust can be a potent occupational asthma trigger.
    • Early identification and reduction of exposure are key to managing plexiglas-induced asthma.
    • This case highlights the importance of targeted inhalation testing in diagnosing occupational respiratory diseases.
