Lupus erythematosusLupus erythematosus (also known as systemic lupus erythematosus - SLE) is an autoimmune disorder where antibodies are created against the body's own DNA.
Like other autoimmune disease, it affects mostly women and its cause is unknown. It can present with a characteristic butterfly-shaped rash of the face, causing a wolf-like appearance (lupus is Latin for wolf).
The immune system becomes hyperactive and attacks normal tissue. Lupus is a chronic disease; there are some treatments for the symptoms, but no cure is known. In lupus, autoimmune attacks result in inflammation, which in turn brings about a variety of symptoms.
