Lupus nephritis is an inflammation of the kidney caused by systemic lupus erythematosus (SLE), a disease of the immune system. Apart from the kidneys, SLE can also damage the skin, joints and nervous system.

Signs and symptoms

Sufferers of lupus nephritis may, or may not have symptoms of kidney disease, but it can manifest itself through weight gain, high blood pressure, dark urine, or swelling around the eyes, legs, ankles, or fingers.

Diagnoses

Diagnoses may utilize blood and urine tests, X-rays and scans of the kidneys, and a kidney biopsy.

Treatment

Medicines can decrease swelling, lower blood pressure, and decrease inflammation by suppressing the immune system. Patients may need to limit protein, sodium, and potassium intake in their diet.
