IgA Nephropathy

IgA nephropathy (IgAN), a rare kidney disorder, is considered the most prevalent primary chronic glomerular disease worldwide.

It is caused by deposits of immunoglobulin A (IgA) in the kidney and characterized by hematuria (blood in the urine), proteinuria, and variable rates of progressive renal failure. Other common symptoms of IgAN may include upper respiratory tract infection, GI or urinary infection, edema, and groin pain.

IgAN affects males two to three times more often than females and is believed to affect as many as 165,000 people in the United States. It is one of the leading causes of acute nephritis in young people in the United States, Europe and Japan.1

With this disease, there is often a slow progression toward chronic kidney failure. There are no approved treatments for IgAN. Patients are currently managed with angiotensin receptor blockers and angiotensin converting enzyme inhibitors, with immunosuppression generally reserved for IgAN patients with severe proteinuria or rapid progression of renal failure.

The following organizations may be a resource for information and support for people with IgAN and those around them:
