Additional Information

Definition, EtiologyTop

Anti–glomerular basement membrane (anti-GBM) disease is a vasculitis affecting glomerular capillaries and/or pulmonary capillaries, uniquely associated with the deposition antibodies to the GBM in the membrane. Pulmonary involvement leads to pulmonary hemorrhage, whereas renal involvement results in glomerulonephritis with necrosis and crescents. Historically, the eponym “Goodpasture syndrome” has referred to the combined pulmonary and renal manifestations of anti-GBM disease.

Clinical Features and Natural HistoryTop

Clinical features:

1) General symptoms: Malaise, fever, arthralgia.

2) Symptoms of pulmonary hemorrhage (see Diffuse Alveolar Hemorrhage) can include dyspnea, cough, hemoptysis, fever, respiratory failure, and shock.

3) Symptoms of rapidly progressive glomerulonephritis: Peripheral edema, hypertension. In 30% of patients the time between the onset of renal and pulmonary symptoms is from one week to one year.

4) Other symptoms: Nausea, vomiting, diarrhea.

The disease is usually rapidly progressive and leads to acute respiratory and renal failure. The main causes of death are pulmonary hemorrhage and respiratory failure. Long-term complications include chronic kidney disease, pulmonary fibrosis, and chronic respiratory failure.

DiagnosisTop

Diagnosis is based on the clinical features, positive circulating antibodies to the GBM, and characteristic histologic features of renal biopsy specimens.

Laboratory findings reveal elevations in the erythrocyte sedimentation rate and C-reactive protein levels, normocytic or microcytic hypochromic anemia, leukocytosis (often with eosinophilia), and signs of renal involvement (creatinine, active sediment [cellular casts], proteinuria <3 g/d in urinalysis), antibodies to the GBM (in 80%-90% of patients), myeloperoxidase (MPO) antineutrophil cytoplasmic antibody (ANCA) (in 10%-40%). Chest radiographs, high-resolution computed tomography, and bronchoalveolar lavage reveal abnormalities typical for pulmonary hemorrhage.

Differential Diagnosis

1. Other causes of pulmonary-renal syndrome (see Granulomatosis with Polyangiitis).

2. Causes of diffuse alveolar hemorrhage other than vasculitis.

3. Other types of acute glomerulonephritis (see Glomerular Diseases).

4. Renal vein thrombosis with pulmonary embolism.

5. Heart failure with renal failure.

TreatmentTop

Plasmapheresis (use repeatedly until complete removal of antibodies to the GBM) with cyclophosphamide and prednisone is the standard treatment for anti-GBM disease, particularly for improving renal outcomes.Evidence 1Strong recommendation (benefits clearly outweigh downsides; right action for all or almost all patients). Moderate Quality of Evidence (moderate confidence that we know true effects of the intervention). Quality of Evidence lowered due to the observational nature of study but strong clinical effect.

In treatment of refractory disease, rituximab may be used.Evidence 2Weak recommendation (benefits likely outweigh downsides, but the balance is close or uncertain; an alternative course of action may be better for some patients). Low Quality of Evidence (low confidence that we know true effects of the intervention). Quality of Evidence lowered due to the presence of small case studies, imprecision, indirectness, and risk of bias. Shah Y, Mohiuddin A, Sluman C, et al.

From 60% to 90% of patients receiving appropriate treatment survive the acute phase of the disease. Treatment is less effective in patients presenting with renal failure. Up to 50% of patients eventually require renal replacement therapy.
