Bronchial provocation studies in farmers allergic to storage mites
Lancet (London, England)
|December 22, 1979
Summary
Farmers exposed to hay and grain dust experience allergic respiratory disease due to storage mites. These mites, found in high numbers, may cause asthma and should be considered in diagnosing farmers lung.
Area of Science:
- Agricultural science
- Allergology
- Occupational health
Background:
- Farmers are frequently exposed to dust from hay and grains.
- Allergic respiratory diseases are common in agricultural communities.
Purpose of the Study:
- To investigate the link between storage mites and allergic respiratory symptoms in farmers.
- To determine if immediate type-I hypersensitivity reactions are involved.
Main Methods:
- Clinical assessment of farmers' respiratory symptoms.
- Evaluation of exposure levels to storage mites in farming environments.
Main Results:
- Clinical responses indicated immediate type-I hypersensitivity.
- Farmers showed significant exposure to storage mites, especially during cattle feeding.
- Storage mites are implicated as a potential cause of asthma in farmers.
Conclusions:
- Storage mites are a significant factor in allergic respiratory disease among farmers.
- Consider storage mites in the differential diagnosis of farmers lung and occupational asthma.
