Lupus Nephritis: Causes, Symptoms, and Treatment Options

When lupus nephritis, a type of kidney inflammation caused by systemic lupus erythematosus. Also known as SLE nephritis, it happens when the immune system attacks the kidneys, leading to damage that can worsen without treatment. This isn’t just a side effect of lupus—it’s one of the most serious complications, affecting up to 60% of people with systemic lupus erythematosus over time.

Lupus nephritis is part of a bigger picture called systemic lupus erythematosus, a chronic autoimmune disease that can target multiple organs. Unlike some forms of kidney disease that come from diabetes or high blood pressure, lupus nephritis stems from your own immune system going rogue. It doesn’t just cause swelling or fatigue—it can lead to protein in the urine, high blood pressure, and even kidney failure if ignored. The signs are often subtle at first: foamy urine, puffy ankles, unexplained weight gain, or dark-colored urine. Many people mistake these for minor issues until a blood test shows real damage.

What makes lupus nephritis tricky is that it doesn’t follow the same path for everyone. Some people have mild flare-ups that respond to steroids, while others need strong immunosuppressants like mycophenolate or cyclophosphamide. There’s no one-size-fits-all treatment, and managing it means watching for flare-ups, controlling blood pressure, and avoiding NSAIDs that can hurt the kidneys even more. The good news? Early detection and consistent care can stop it from progressing. Many patients live full lives with proper monitoring and medication.

You’ll also see how this connects to other conditions like autoimmune kidney damage, a broader category that includes diseases where the immune system attacks kidney tissue. While lupus nephritis is the most common cause, others like IgA nephropathy or vasculitis can look similar. That’s why accurate diagnosis matters—biopsies, urine tests, and blood markers like anti-dsDNA and complement levels help doctors tell the difference.
