Immunoglobulin A Nephropathy

IgA nephropathy (nuh-FROP-uh-thee), also known as Berger's disease, is a kidney disease that occurs when an antibody called immunoglobulin A (IgA) builds up in your kidneys. This results in local inflammation that, over time, can hamper your kidneys' ability to filter waste from your blood.

IgA nephropathy usually progresses slowly over years, but the course of the disease varies from person to person. Some people leak blood in their urine without developing problems, some eventually achieve complete remission and others develop end-stage kidney failure.

No cure exists for IgA nephropathy, but certain medications can slow its course. Keeping your blood pressure under control and reducing your cholesterol levels also slow the disease.
