Anti-GBM disease (Goodpasture disease)
Anti-glomerular basement membrane (anti-GBM) disease is a rare autoimmune disorder in which antibodies attack basement membranes in the kidney glomeruli and sometimes the lungs. It can cause rapidly progressive glomerulonephritis and life-threatening pulmonary hemorrhage, so early recognition and treatment are critical.

Names & terminology
How this entity may be named or searched
- Anti-GBM disease
- Preferred pathophysiologic term for disease caused by circulating antibodies against glomerular basement membrane.
- Goodpasture disease
- Common historical/clinical synonym for anti-GBM antibody disease.
- Goodpasture syndrome
- Sometimes used more broadly for pulmonary–renal syndrome; not every pulmonary–renal syndrome is caused by anti-GBM antibodies.
- Pulmonary hemorrhage
- Bleeding into the lung airspaces can occur with or without obvious coughing of blood.
Structured entity profile
Clinical profile
Overview
Anti-GBM disease develops when the immune system produces antibodies against a target within basement membranes, particularly in kidney glomeruli and lung alveoli. Kidney injury can progress over days to weeks, producing a rapidly progressive form of glomerulonephritis. Lung involvement can cause diffuse alveolar hemorrhage, which may be clinically obvious or may present mainly as breathlessness and falling hemoglobin. [1] [2]
The condition is rare—NIDDK cites roughly one new case per million people per year. Because outcome depends strongly on kidney function at treatment and the amount of irreversible injury already present, suspected anti-GBM disease is a nephrology emergency rather than a diagnosis to confirm slowly in routine follow-up. [1] [2]
Symptoms and warning signs
Kidney symptoms may include dark or bloody urine, swelling, reduced urine output, nausea, fatigue and high blood pressure, although laboratory abnormalities can precede obvious symptoms. Lung bleeding can cause cough, shortness of breath, chest discomfort or coughing blood; some patients have substantial alveolar bleeding without dramatic hemoptysis. Pallor and fatigue may reflect anemia. [1]
SYMPTOM MATRIX
Think pulmonary–renal syndrome when kidney injury and lung bleeding occur together
Either organ can dominate the initial presentation.
- Blood in urine
- Protein in urine
- Rapidly rising creatinine
- Reduced urine output
- Edema / high blood pressure
- Cough
- Shortness of breath
- Coughing blood
- Falling hemoglobin / anemia
- New diffuse lung infiltrates
- Rapid kidney failure
- Very low urine output
- Coughing blood with breathlessness
- Low oxygen or diffuse pulmonary hemorrhage
- Severe fluid or electrolyte complications
Suspected anti-GBM disease usually requires urgent nephrology assessment and treatment planning.
Diagnosis
Blood testing for anti-GBM antibodies is central. Urinalysis typically shows hematuria and proteinuria, and blood tests assess creatinine, potassium, hemoglobin and inflammatory or autoimmune alternatives. Because some patients have overlapping ANCA-associated vasculitis, ANCA testing is usually included in a pulmonary–renal syndrome work-up. [1] [2]
Kidney biopsy usually shows crescentic glomerulonephritis and characteristic strong linear staining for IgG along the glomerular basement membrane. The biopsy also estimates how much kidney tissue is still salvageable and helps guide prognosis. Chest imaging and respiratory evaluation assess pulmonary hemorrhage when lung involvement is suspected. [1] [2]
Diagnostic pathway
Confirm antibody disease quickly while staging kidney and lung injury
Testing and treatment may proceed in parallel when the presentation is strongly suggestive.
A small minority of clinically compatible cases may have negative circulating antibody assays, making biopsy particularly important.
Risk factors and possible triggers
Anti-GBM disease is autoimmune and is not contagious. Cigarette smoking and inhaled hydrocarbon exposure have been associated with pulmonary involvement in susceptible people. Respiratory infection or lung injury may also precede disease in some patients, but most cases cannot be reduced to one avoidable trigger. [1]
Overlap with ANCA-associated vasculitis
Some patients are positive for both anti-GBM antibodies and ANCA. These “double-positive” cases can have features of both diseases: acute anti-GBM-type organ injury plus a higher long-term relapse tendency associated with ANCA vasculitis. Identifying overlap affects follow-up even after the acute antibody level becomes negative. [2]
Treatment and management
Standard treatment for active, organ-threatening anti-GBM disease combines plasma exchange, which removes circulating antibodies, with corticosteroids and another immunosuppressive agent to suppress new antibody production. Treatment is generally continued until circulating anti-GBM antibodies are no longer detectable and the acute inflammatory phase is controlled. [1] [2]
Dialysis supports patients with severe kidney failure but does not treat the autoimmune process itself. Kidney recovery is less likely when presentation is very advanced, particularly with dialysis dependence and extensive irreversible crescentic damage, so treatment intensity is individualized. Kidney transplantation is possible after disease is inactive, typically after a sustained period without detectable antibodies. [1] [2]
Treatment & care hub
Remove antibody, stop new antibody production, support failing organs
Anti-GBM disease is one of the classic indications for urgent plasma-exchange-based therapy.
Remove circulating anti-GBM antibody
Repeated exchanges lower antibody burden during active disease.
Stop further antibody production
Corticosteroids plus another immunosuppressive agent are commonly used.
Dialysis for severe kidney failure
Dialysis treats complications while the autoimmune process is addressed.
Manage pulmonary hemorrhage
Oxygen, transfusion and critical-care support may be required in severe bleeding.
Treatment choices depend on kidney salvageability, pulmonary hemorrhage and overall clinical status and should be made by specialist teams.
Prognosis and kidney recovery
Outcome is strongly linked to kidney function and biopsy findings at diagnosis. Patients treated before advanced kidney failure have a better chance of preserving kidney function. Severe presentation with dialysis dependence and extensive crescentic or scarred glomeruli is associated with lower renal recovery, although pulmonary hemorrhage can often respond well to treatment. [1] [2]
Follow-up after the acute episode
Clinicians follow anti-GBM antibody levels, kidney function, urinalysis, blood counts and respiratory status. Classic isolated anti-GBM disease has a relatively low relapse rate once antibodies disappear, while double-positive ANCA cases need longer vasculitis-oriented surveillance. Smoking cessation is especially important in anyone with prior pulmonary hemorrhage. [1] [2]
Rare disease
Anti-GBM disease is reported in roughly 1 person per million each year
Its rarity makes rapid recognition of the pulmonary–renal pattern especially important.
Common questions
Frequently asked questions
Goodpasture disease is a common name for anti-GBM antibody disease, although “Goodpasture syndrome” is sometimes used more broadly for pulmonary–renal syndromes.
Diagnosis uses anti-GBM antibody testing, kidney and urine tests, and usually kidney biopsy showing characteristic linear IgG staining.
The same autoimmune target is present in lung alveolar basement membranes, so capillary injury can cause pulmonary hemorrhage.
Plasma exchange removes circulating anti-GBM antibodies while immunosuppressive medicines reduce new antibody production.
Recovery is possible, especially when treatment begins before advanced irreversible injury; prognosis is worse with dialysis dependence and extensive chronic damage at presentation.
