Definition    Return to top

Goodpasture syndrome is a rare disease that involves rapidly progressive kidney failure along with lung disease.

However, some forms of the disease involve just the lung or kidney, not both.

Causes    Return to top

Goodpasture syndrome is an autoimmune disorder, a condition that occurs when the immune system mistakenly attacks and destroys healthy body tissue. Persons with this syndrome develop substances that attack a protein called collagen in the tiny air sacs in the lungs and the filtering units (glomureli) of the kidney.

These substances are called anti-glomerular basement membrane antibodies. Glomerular basement membrane is a part of the kidneys that helps filter waste and extra fluid from the blood. Anti-glomerular basement membrane are antibodies against this membrane. They can lead to kidney damage.

Sometimes the 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 and inflammation in the kidney's filtering units.

Men are eight times more likely to be affected than women. The disease most commonly occurs in early adulthood.

Exams and Tests    Return to top

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 usually abnormal, and shows blood and protein in the urine. Abnormal red blood cells may be seen.

The following tests may also be done:

Treatment    Return to top

The main goal is to remove the antibodies from the blood. A treatment called plasmapheresis removes blood from the body and replaces it with fluid, protein, or donated plasma.

Powerful anti-inflammatory and cytotoxic medicines (such as prednisone or cyclophosphamide) may be needed.

If kidney failure becomes severe, dialysis may be needed.

Kidney transplantation may be need if you have permanent loss of kidney function. The transplant is usually not done until the level of antibodies drop.

Outlook (Prognosis)    Return to top

An early diagnosis is very important. The patient's outlook is much worse if the kidneys are already severely damaged when treatment begins.

When to Contact a Medical Professional    Return to top

Call for an appointment with your health care provider if the amount of urine you produce drops, or if you have any other symptoms of Goodpasture syndrome.

Prevention    Return to top

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