Systemic lupus erythematosus (SLE), commonly referred to as simply "lupus," is an autoimmune disorder where the body's immune system attacks healthy tissue. Lupus affects somewhere between 20 to 150 people per 100,000, with variations among different racial and ethnic groups. The disease often causes arthritic symptoms in the joints, which can be debilitating in some cases.
