Background
- Goodpasture syndrome (60%): diffuse alveolar hemorrhage + acute glomerulonephritis
- Goodpasture disease: glomerulonephritis alone (30%,) pulmonary symptoms alone (10%,)
- Anti-GBM disease is most precise term for both entities
- Type II hypersensitivity causing linear IG deposition in glomerular and alveolar BM
- Triggered by:
- Sepsis
- URI
- Inhalation injury
- Smoking
- Pulmonary edema
Clinical Features
- Constitutional symptoms prior to pulmonary/renal complications
- Pulmonary
- Renal: glomerulonephritis
- Hematuria, proteinuria, RBC casts
- Symptoms are often rapidly progressive
Differential Diagnosis
Hemoptysis
- Infectious
- Neoplastic
- Lung cancer
- Metastatic cancer
- Cardiovascular
- Pulmonary embolism
- Congestive heart failure
- Pulmonary hypertension
- AV malformation
- Mitral stenosis
- Alveolar hemorrhage syndromes
- Hematologic
- Uremia
- Platelet dysfunction (ASA, clopidogrel)
- Anticoagulant therapy
- Traumatic
- Foreign body aspiration
- Ruptured bronchus
- Inflammatory
- Miscellaneous
- Cocaine inhalation (crack lung)
- Catamenial pneumothorax
- Goodpasture syndrome
- Cystic fibrosis
- Epistaxis
- Blood-laced mucus from the sinus or nose area
- Upper GI bleeding
Causes of Glomerulonephritis
- Poststreptococcal glomerulonephritis
- Hemolytic-uremic syndrome
- Henoch-Schonlein purpura
- IgA nephropathy
- Lupus nephritis
- Alport syndrome
- Goodpasture syndrome
- Paraneoplastic
Evaluation
- Pulmonary
- Depends whether patient stable or not, massive hemoptysis or not
- Consider: CXR vs CT chest w/contrast, CBC, coags, T&S, bronchoscopy
- Renal:
- Urinalysis, CBC, Chemistry, Albumin (often reduced in acute glomerulonephritis,) C3, C4, ASO, ANCA
Management
- See Hemoptysis
- Massive: intubate (ideally ETT >8.0), angio or bronch to identify and stop localized source, consider nebulized TXA
- Correct coagulopathy
- Methylprednisolone 1g + plasmapheresis
- See Glomerulonephritis, consult nephrology
- Plasmapheresis shown to be beneficial [1]
- In severe cases may need:
- Rheumatology eval: Immunosuppressants
Disposition
Admit for:
- Decompensated disease
- Massive hemoptysis
- Acute glomerulonephritis
