Systemic lupus erythematosus (SLE) is a long-term autoimmune-disorder that may affect the skin, joints, kidneys, brain, and other organs.
Autoimmune-disorder is when the body's immune system mistakenly attacks healthy tissue. When Lupus is present, it leads to long-term (chronic) inflammation.
Lupus is much more common in women than men. It may occur at any age, but appears most often in people between the ages of 10 and 50. African Americans and Asians are affected more often than people from other races.
