Coffee-workers' lung

Last edited: 4/22/2026

Overview

Coffee-workers' lung, also known as coffee dust lung disease, refers to respiratory conditions affecting workers in coffee processing environments due to inhalation of coffee bean dust, potentially leading to hypersensitivity pneumonitis or chronic obstructive pulmonary disease (COPD)-like symptoms 1.

Diagnosis

  • Clinical History: Exposure to coffee bean dust in occupational settings 1.
  • Pulmonary Function Tests (PFTs): Reveal restrictive or obstructive patterns depending on the severity and chronicity 1.
  • Bronchoalveolar Lavage (BAL): May show lymphocytosis indicative of hypersensitivity 1.
  • Pulmonary Imaging: Chest X-rays or CT scans can show interstitial changes or emphysema-like features 1.
  • Specific IgE Testing: Elevated levels for coffee allergens can support the diagnosis 1.
  • Bronchoprovocation Tests: Useful in confirming hypersensitivity pneumonitis 1.

    • Management

  • Avoidance of Exposure: Primary prevention by improving workplace ventilation and dust control measures 1.
  • Corticosteroids: First-line treatment for acute exacerbations or severe cases, typically oral prednisone tapering over weeks 1.
  • Immunosuppressants: Considered in refractory cases, such as azathioprine or methotrexate, under specialist guidance 1.
  • Oxygen Therapy: For patients with hypoxemia 1.
  • Pulmonary Rehabilitation: To improve functional capacity and quality of life 1.
  • Regular Monitoring: Ongoing PFTs and clinical assessments to manage disease progression 1.

    • Special Populations

  • Pregnancy: Limited data; avoidance of exposure critical; symptomatic management similar to non-pregnant adults 1.
  • Pediatrics: Not specifically addressed in provided abstracts; general principles of exposure avoidance apply 1.
  • Elderly: Increased susceptibility to respiratory complications; close monitoring and supportive care essential 1.
  • Comorbidities: Presence of COPD or other respiratory conditions may complicate management; tailored approach advised 1.

    • Key Recommendations

  • Implement strict workplace dust control measures to prevent exposure 1 (Evidence: Expert opinion).
  • Initiate corticosteroid therapy for confirmed cases of hypersensitivity pneumonitis 1 (Evidence: Moderate).
  • Regularly monitor affected workers with pulmonary function tests and clinical evaluations 1 (Evidence: Moderate).
