Systemic Lupus Erythematosus with Lupus Nephritis
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect various parts of the body, including the skin, joints, and organs. When it involves the kidneys, it's known as lupus nephritis, which can lead to kidney inflammation and damage, causing symptoms like swelling, high blood pressure, and changes in urine.
