What is Goodpasture syndrome?
Goodpasture syndrome is a rare autoimmune disease that affects the lungs and kidneys. In this condition, the immune system mistakenly attacks healthy tissue instead of protecting the body from infection.
The disease can cause bleeding in the lungs and inflammation in the kidneys. Without prompt treatment, it may lead to serious kidney damage or kidney failure.
The exact cause of Goodpasture syndrome is not fully understood. Experts believe a combination of genetics and environmental triggers may play a role. Smoking, certain chemical exposures, and respiratory infections have all been linked to a higher risk of developing the condition.
Symptoms
Symptoms of Goodpasture syndrome can appear suddenly and may become severe quickly. Some people first notice breathing problems, while others develop signs of kidney disease.
Common symptoms may include:
- Fatigue or weakness
- Shortness of breath
- Pale skin
- Nausea
- Coughing up blood
- Blood in the urine
- Foamy urine from excess protein
- Burning or discomfort during urination
- Swelling in the legs, feet, or face
How is it diagnosed?
Healthcare providers diagnose Goodpasture syndrome by reviewing your symptoms, medical history, and test results. Because the disease can progress quickly, early testing is important.
Diagnostic testing may include:
- Blood tests to check kidney function and look for specific antibodies
- Urine tests to detect blood or protein
- Chest X-rays or other imaging to examine the lungs
- A kidney biopsy to confirm inflammation and damage
- In some cases, a lung biopsy
How is it treated?
Treatment focuses on stopping the immune system from attacking the lungs and kidneys while protecting organ function.
Many people begin treatment with medications such as corticosteroids and immunosuppressants to reduce inflammation and slow the immune response. Providers may also use plasmapheresis, a treatment that filters harmful antibodies from the blood.
If kidney damage becomes severe, dialysis may be needed to help the body remove waste and extra fluid. In advanced cases, a kidney transplant may be considered.
Early treatment can improve outcomes and may help prevent permanent organ damage. Lung symptoms often improve with treatment, but kidney problems may last longer if significant damage has already occurred.
