The main goal is to remove the harmful antibodies from the blood. A treatment called plasmapheresis removes whole blood from the body and replaces the plasma with fluid, protein, or donated plasma. Removing harmful antibodies may reduce inflammation in the kidneys and lungs.
Corticosteroid medications (such as prednisone) and other drugs that suppress or quiet the immune system may be used.
Controlling blood pressure is the most important way to delay kidney damage. You may get medicines to control high blood pressure, such as angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs).
You may be told to limit salt and fluids to control swelling. A low to moderate protein diet may be recommended in some cases.
You should be closely watched for signs of kidney failure. If kidney failure becomes severe, you may need dialysis.
If you permanently lose kidney function, you may need a kidney transplant. A transplant is not done until the level of harmful antibodies drops.
