Key Points about Extrinsic Allergic Alveolitis:

  • Definition: Extrinsic Allergic Alveolitis (also known as Hypersensitivity Pneumonitis) is an inflammatory lung disease caused by inhalation of organic dusts, leading to an immune-mediated response in the lungs.
  • Causes: Common causes include exposure to moldy hay (farmer’s lung), bird droppings (bird fancier’s lung), and other organic particles.
  • Symptoms: Acute episodes include cough, shortness of breath, and fever, while chronic exposure can lead to progressive lung scarring.
  • Diagnosis: Diagnosis involves a combination of patient history (exposure to known triggers), imaging (e.g., chest X-ray, CT), and pulmonary function tests showing restrictive lung disease.
  • Management: Avoidance of the triggering antigen is the primary management, along with corticosteroids for severe cases.
  • Complications: Chronic exposure can lead to pulmonary fibrosis, respiratory failure, and long-term disability if untreated.
