    Two plaster workers developed hypersensitivity pneumonitis, a lung disease. Immunological tests from bronchoalveolar lavage aided diagnosis and monitoring of alveolitis.

    Area of Science:

    • Pulmonary Medicine
    • Immunology
    • Occupational Health

    Background:

    • Diffuse interstitial lung disease can arise from occupational exposures.
    • Hypersensitivity pneumonitis is an immune-mediated lung disease often triggered by inhaled antigens.

    Observation:

    • Two plaster workers presented with diffuse interstitial lung disease.
    • Clinical, histological, and immunological findings suggested hypersensitivity pneumonitis.
    • Bronchoalveolar lavage revealed increased activated T cells, Natural Killer cells, and immunoglobulins.

    Findings:

    • The study highlights the diagnostic utility of bronchoalveolar lavage immunological analysis in hypersensitivity pneumonitis.
    • While the specific antigen remained uncharacterized, immunological profiles supported the diagnosis.

  • Lymphocytic predominance in bronchoalveolar lavage is crucial for diagnosing alveolitis.

    • Implications:

    • Immunological assessment of bronchoalveolar lavage is vital for diagnosing occupational lung diseases like hypersensitivity pneumonitis.
    • 99mTc-DTPA gammagraphy may serve as a useful tool for monitoring alveolitis progression in affected patients.
