What are the causes of Lupus Nephritis?

Systemic lupus erythematosus (SLE, or lupus) is an autoimmune disease. This means there is a problem with the body's immune system.

Normally, the immune system helps protect the body from infection or harmful substances. But in people with an autoimmune disease, the immune system cannot tell the difference between harmful substances and healthy ones. As a result, the immune system attacks otherwise healthy cells and tissues.

SLE may damage different parts of the kidney. This can lead to disorders such as:

  • Interstitial nephritis
  • Nephrotic syndrome
  • Membranous glomerulonephritis
  • Kidney failure
What are the symptoms of Lupus Nephritis?

Symptoms of lupus nephritis include:

  • Blood in the urine
  • Foamy appearance to urine
  • Swelling (edema) of any area of the body
  • High blood pressure

What are the current treatments for Lupus Nephritis?

The goal of treatment is to improve kidney function and to delay kidney failure.

Medicines may include drugs that suppress the immune system, such as corticosteroids, cyclophosphamide, mycophenolate mofetil, or azathioprine.

You may need dialysis to control symptoms of kidney failure, sometimes for only a while. A kidney transplant may be recommended. People with active lupus should not have a transplant because the condition can occur in the transplanted kidney.

Efficacy of Belimumab and Rituximab Compared to Rituximab Alone for the Treatment of Primary Membranous Nephropathy (ITN080AI)

This damage can cause the loss of too much protein in the urine. Drugs ...
