[Some observations on farmer's lung (author's transl)]
Wiener Klinische Wochenschrift
|December 11, 1981
Summary
Farmer's lung diagnosis was confirmed in 17 patients using serological tests. Micropolyspora faeni was identified as the most common antigen triggering positive reactions in this occupational lung disease.
Area of Science:
- Immunology
- Occupational Medicine
- Pulmonology
Context:
- Farmer's lung is a hypersensitivity pneumonitis caused by inhaled organic dusts.
- Occupational exposure to antigens like Micropolyspora faeni can trigger immune responses.
- Accurate diagnosis is crucial for managing this occupational lung disease.
Purpose:
- To investigate the serological responses in patients with farmer's lung.
- To identify specific antigens responsible for positive reactions.
- To evaluate immunoglobulin levels in affected individuals.
Summary:
- Sera from 72 patients with farmer's lung symptoms were tested against various antigens.
- Precipitating antibodies were detected in 23 cases, with Micropolyspora faeni being the most frequent antigen.
- Exogen allergic alveolitis was diagnosed in 17 seropositive patients, showing elevated IgG and IgA levels.
Impact:
- This study aids in understanding the immunological basis of farmer's lung.
- It supports the classification of farmer's lung as an occupational disease in Austria.
- Findings can inform diagnostic strategies and occupational health policies for respiratory diseases.
