Organising Pneumonia, including its idiopathic form Cryptogenic Organising Pneumonia, is an inflammatory lung disease. Corticosteroid therapy is effective, though relapses are common but manageable.

Area of Science:

  • Pulmonology
  • Respiratory Medicine
  • Pathology

Background:

  • Organising Pneumonia (OP) is an inflammatory and fibroproliferative lung disease.
  • Cryptogenic Organising Pneumonia (COP) is the idiopathic form, recently defined by ATS/ERS consensus.
  • Characterized by subacute onset with cough, dyspnea, fever, and constitutional symptoms.

Purpose of the Study:

  • To define the clinical, radiological, and histological features of Organising Pneumonia.
  • To outline diagnostic criteria for Organising Pneumonia.
  • To discuss therapeutic strategies and prognosis for Organising Pneumonia.

Main Methods:

  • Diagnosis relies on integrating clinical presentation, chest imaging (multifocal alveolar opacities), and lung biopsy findings (budding connective tissue).

  • Bronchoalveolar lavage often shows a mixed alveolitis (lymphocytes, neutrophils, eosinophils).
  • Evaluation involves differentiating OP from other lung diseases to avoid misdiagnosis.

    • Main Results:

    • Patients typically present with cough, dyspnea, fever, and elevated inflammatory markers.
    • Chest imaging commonly reveals migratory, subpleural alveolar opacities.
    • Lung biopsy shows characteristic fibroproliferative changes in distal airspaces.

    Conclusions:

    • Organising Pneumonia is a distinct inflammatory lung condition with specific diagnostic markers.
    • Corticosteroid therapy is generally effective, leading to good responses.
    • Relapses are frequent but manageable with prednisone, without significantly impacting long-term prognosis.
