Goodpasture syndrome; Rapidly progressive glomerulonephritis with pulmonary hemorrhage; Pulmonary renal syndrome; Glomerulonephritis - pulmonary hemorrhage DefinitionAnti-glomerular basement membrane disease (anti-GBM disease) is a rare disorder that can involve quickly worsening kidney failure and lung disease. Some forms of the disease involve just the lungs or the kidneys. Anti-GBM disease used to be known as Goodpasture syndrome. CausesAnti-GBM disease is an autoimmune disorder. It occurs when the immune system mistakenly attacks and destroys healthy body tissue. People with this syndrome develop substances that attack a protein called collagen in the tiny air sacs in the lungs and the filtering units (glomeruli) of the kidneys. These substances are called antiglomerular basement membrane antibodies. The glomerular basement membrane is a part of the kidneys that helps filter waste and extra fluid from the blood. Antiglomerular basement membrane antibodies are antibodies against this membrane. They can damage the basement membrane, which can lead to kidney damage. Sometimes, this disorder is triggered by a viral respiratory infection or by breathing in hydrocarbon solvents. In such cases, the immune system may attack organs or tissues because it mistakes them for these viruses or foreign chemicals. The immune system's faulty response causes bleeding in the air sacs of the lungs and inflammation in the kidney's filtering units. SymptomsSymptoms may occur very slowly over months or even years, but they often develop very quickly over days to weeks. Loss of appetite, fatigue, and weakness are common early symptoms. Lung symptoms may include:
Kidney and other symptoms include:
Exams and TestsA physical exam may reveal high blood pressure and signs of fluid overload. Your health care provider may hear abnormal heart and lung sounds when listening to the chest with a stethoscope. Urinalysis results are often abnormal and show blood and protein in the urine. Abnormal red blood cells may be seen. The following tests may also be done:
TreatmentThe main goal is to remove the harmful antibodies from the blood. Treatment may include:
You may be told to limit your intake of salt and fluids to control swelling. In some cases, a low-to-moderate protein diet may be recommended. Support GroupsMore information and support for people with anti-GBM disease and their families can be found at:
Outlook (Prognosis)An early diagnosis is very important. The outlook is much worse if the kidneys are already severely damaged when treatment begins. Lung damage can range from mild to severe. Many people will need dialysis or a kidney transplant. Possible ComplicationsUntreated, this condition can lead to any of the following:
When to Contact a Medical ProfessionalContact your provider for an appointment if you are producing less urine, or you have any other symptoms of anti-GBM disease. PreventionNever sniff glue or siphon gasoline with your mouth, which exposes the lungs to hydrocarbon solvents and can cause the disease. ReferencesPhelps RG, Turner AN.
