what is active lupus
There are two types of lupus. Systemic lupus erythematosus (SLE) is the form of lupus that can harm your skin, joints, kidneys and brain and may be fatal. The other form of lupus is called discoid lupus erythematosus, which affects only your skin. Systemic lupus erythematosus (SLE) that affects the kidneys is called lupus nephritis. Lupus is an autoimmune disease, meaning your immune system (your bodyâs defense system), which usually protects the body from disease, turns against the body. This causes harm to organs and tissues, like your kidneys.
