Summary
Textile aerography workers exposed to toxic substances developed lung damage, including bronchiolitis obliterans with organized pneumonia (BOOP) and reactive airways dysfunction syndrome, persisting for at least 18 months.
Area of Science:
- Occupational Medicine
- Pulmonology
- Toxicology
Background:
- Textile aerography involves exposure to potentially toxic and irritant substances.
- Understanding the long-term respiratory effects of such exposures is crucial for worker health.
Purpose of the Study:
- To investigate the initial and 18-month respiratory consequences of inhaling toxic and irritant agents in textile aerography workers.
Main Methods:
- Seventeen textile aerography workers underwent initial pulmonary assessment including transbronchial biopsy, video-thoracoscopy, spirometry, and CO diffusion capacity (DLCO) measurement.
- Eighteen months post-exposure, a bronchial challenge test with histamine was administered.
Main Results:
- Pathological findings included intraalveolar fibrin (41%), non-specific lesions (35%), and bronchiolitis obliterans with organized pneumonia (BOOP) (18%).
- Functional tests revealed restrictive patterns and reduced DLCO in several patients.
- Histological repairing lesions and non-specific bronchial hyperreactivity (59%) were observed, suggesting reactive airways dysfunction syndrome.
Conclusions:
- Massive inhalation of irritant/toxic substances in textile aerography workers leads to diverse pulmonary pathological responses.
- Bronchiolitis obliterans with organized pneumonia (BOOP) was a frequent finding, alongside functional impairments.
- A significant proportion of workers developed bronchial hyperreactivity, indicative of reactive airways dysfunction syndrome.
