Osmosis video - Systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease in which the body's immune system mistakenly attacks healthy tissue. SLE most often harms the heart, joints, skin, lungs, blood vessels, liver, kidneys, and nervous system. Common symptoms of SLE can include fatigue, joint pain, rash, fever, and anemia. The course of the disease is unpredictable, with periods of illness (called flare-ups) alternating with remissions. Treatment typically involves medications to manage symptoms, reduce inflammation, and suppress the immune system.
