Background

  • Diffuse Alveolar Hemorrhage (DAH) is a life-threatening condition.
  • It is a subset of Pulmonary hemorrhage involving the microcirculation involving alveolar microvasculature.
  • Most commonly the result of systemic vasculitis. [1]

Clinical Features

  • Hemoptysis
  • Anemia
  • Diffuse lung infiltrates
  • Acute respiratory failure

Differential Diagnosis

Idiopathic small vessel vasculitis

  • Wegener's granulomatosis
  • Churg-Straus syndrome
  • Microscopic polyangitis

Primary immune complex-mediated vasculitis

  • Goodpasture's syndrome
  • Henoch-Schonlein purpura

Secondary vasculitis

  • Systemic lupus erythematosus
  • Rheumatoid arthritis
  • Mixed connective tissue disease
  • Polymyositis/Dermatomyositis

Acute lung transplant rejection

Drug induced (ie. chemotherapy, amiodarone, propylthiouracil)

ARDS

Coagulopathy

Pulmonic veno-occlusive disease

Mitral stenosis

Diagnosis

Management

General principles

  • Airway stabilization if large volume hemoptysis or problems with oxygenation/ventilation (>8.0 ETT preferable)
  • IV corticosteroids - high dose Methylprednisilone Q6H[2]
  • Bronchoscopy to obtain BAL and localize source of bleeding if localizable
  • Management of Hemoptysis
