Lupus is a chronic inflammatory autoimmune disorder that can affect many different body systems, including the joints, skin, kidneys, blood cells, brain, heart, and lungs. Systemic lupus erythematosus (SLE) refers to the systemic form of the disease, which includes organ-specific variants such as lupus nephritis. This disorder can be very difficult to diagnose as its signs and symptoms often mimic those of other conditions, and a physician is unlikely to ever see two cases that are alike.
