Pneumoconiosis caused by sisal dust

Last edited: 4/16/2026

Overview

Pneumoconiosis caused by sisal dust, also known as sisalosis, results from prolonged inhalation of dust particles from sisal fibers, leading to respiratory inflammation and fibrosis 1. The presence of additives and contaminants in sisal fibers can exacerbate the risk and severity of lung damage 1.

Diagnosis

  • Clinical history: Exposure to sisal dust in occupational settings 1.
  • Pulmonary function tests: Reveal restrictive or obstructive patterns depending on disease severity 1.
  • Chest imaging: Chest X-rays and CT scans show characteristic interstitial changes, reticulonodular opacities, or honeycombing 1.
  • Bronchoalveolar lavage (BAL): May show lymphocytosis and increased neutrophils 1.
  • Histopathology: Biopsy reveals dust-laden macrophages, interstitial fibrosis, and granulomatous inflammation 1.

    • Management

  • Exposure control: Primary prevention through improved workplace ventilation and protective equipment 1.
  • Steroids: Corticosteroids (e.g., prednisone) for acute exacerbations or severe cases to reduce inflammation 1.
  • Immunosuppressants: Consideration of immunosuppressive agents like cyclophosphamide in refractory cases 1.
  • Oxygen therapy: For hypoxemia 1.
  • Pulmonary rehabilitation: To improve functional capacity and quality of life 1.
  • Monitoring: Regular follow-up with pulmonary function tests and imaging to assess disease progression 1.

    • Special Populations

  • Pregnancy: Limited data; close monitoring of respiratory function and fetal well-being is advised 1.
  • Pediatrics: Susceptibility to respiratory complications; stringent exposure prevention measures essential 1.
  • Elderly: Increased risk of severe respiratory complications; aggressive management of symptoms recommended 1.
  • Comorbidities: Presence of other respiratory diseases may worsen outcomes; tailored management strategies needed 1.

    • Key Recommendations

  • Implement strict occupational safety measures to minimize sisal dust exposure (Evidence: Expert opinion) 1.
  • Initiate corticosteroid therapy for symptomatic patients with confirmed sisalosis (Evidence: Moderate) 1.
  • Regularly monitor affected individuals with pulmonary function tests and imaging to guide management (Evidence: Moderate) 1.
