Systemic lupus erythematosus
Systemic lupus erythematosus (also known as lupus or SLE) is an autoimmune disease that can potentially affect many parts of the body including joints, skin, eyes and kidneys. Lupus is mild in many people but is life-threatening in others. People with lupus often have disease flares, in which symptoms worsen, followed by a period of remission, in which symptoms improve. Blood tests are nearly always abnormal which helps to make a diagnosis. Treatments target the abnormal immune system to reduce symptoms, control inflammation, and minimize organ damage. Long term follow up is usually required.
