Systemic lupus erythematosus--what is sle?

Autoimmune disease: A disease in which your body makes antibodies against your own cells. These antibodies cause destruction and inflammation which produce a wide variety of symptoms depending on what cells are being injured. There are some common symptoms and signs with the disease, but just about any symptom could be produced by lupus.

Systemic lupus: Lupus erythematosus is a chronic inflammatory disease of unknown cause. The immune system attacks the patient's own body (autoimmunity) and can inflame the skin, joints, kidneys, nervous system, lungs, mucous membranes, and other internal organs. A red rash is sometimes present hence the term lupus erythematosus meaning "red wolf." when more than skin and joints are involved, it is termed systemic.
