Goodpasture syndrome

Goodpasture syndrome is a rare disease that can involve quickly worsening kidney failure and lung disease.

Some forms of the disease involve just the lung or the kidney.

Causes

Goodpasture syndrome 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.

Symptoms

Symptoms 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:

  • Coughing up blood
  • Dry cough
  • Shortness of breath

Kidney and other symptoms include:

Exams and Tests

A physical examination may reveal signs of high blood pressure and fluid overload. The 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:

Treatment

The main goal is to remove the harmful antibodies from the blood. Treatment may include:

  • Plasmapheresis, which removes harmful antibodies to help reduce inflammation in the kidneys and lungs.
  • Corticosteroid medicines (such as prednisone) and other drugs, which suppress or quiet the immune system.
  • Medicines such as angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), which help control blood pressure.
  • Dialysis, which may be done if kidney failure can no longer be treated.
  • A kidney transplant, which may be done when your kidneys no longer function.

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.

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 Complications

Untreated, this condition can lead to any of the following:

When to Contact a Medical Professional

Call for an appointment with your provider if you are producing less urine, or you have any other symptoms of Goodpasture syndrome.

Prevention

Never sniff glue or siphon gasoline with your mouth, which exposes the lungs to hydrocarbon solvents and can cause the disease.
