    Green coffee allergen exposure can cause immediate asthma and reduced lung function in coffee workers. Bronchoprovocation testing, skin tests, and IgE levels indicate respiratory sensitivity to green coffee dust.

    Area of Science:

    • Occupational Medicine
    • Pulmonary Immunology
    • Allergy and Immunology

    Context:

    • Coffee workers frequently report respiratory symptoms attributed to their work environment.
    • Exposure to green coffee dust is a potential occupational hazard.
    • Understanding the mechanisms of respiratory reactions is crucial for worker health.

    Purpose:

    • To investigate the respiratory effects of green coffee allergen exposure in symptomatic coffee workers.
    • To evaluate the utility of bronchoprovocation testing, skin prick tests, and serum IgE levels in diagnosing hypersensitivity.
    • To identify indicators of respiratory system sensitivity to green coffee dust.

    Summary:

    • Nine coffee workers with job-related respiratory symptoms underwent bronchoprovocation testing with green coffee allergen.

    Related Experiment Videos

  • Four workers experienced immediate asthmatic reactions and significant reductions in ventilatory capacity, particularly in FEF25-75 and FEV1.
  • Eight workers had elevated total IgE levels, and six showed positive skin prick test reactions to green coffee allergen.

    • Impact:

    • Bronchoprovocation testing with green coffee allergen is a valuable diagnostic tool.
    • Skin tests and total IgE serum levels can further indicate respiratory sensitivity.
    • Findings support the identification and management of occupational asthma in the coffee industry.
