A National Kidney Foundation answered. Kidney damage from lupus can be mild or severe. It can cause damage to the filtering units (glomeruli) of the kidney. Since these filtering units clear your blood of waste, damage to them can cause your kidneys to work poorly or not at all.
Systemic lupus erythematosus (SLE) that affects the kidneys is called lupus nephritis. Lupus is an autoimmune disease, meaning your immune system (your bodyâs defense system), which usually protects the body from disease, turns against the body. This causes harm to organs and tissues, like your kidneys.
