Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by the production of autoantibodies that can affect multiple organ systems, leading to inflammation and damage. It is clinically significant due to its varied presentations, which can complicate diagnosis and management, often requiring a multidisciplinary approach. A key association is the increased risk of renal involvement, manifesting as lupus nephritis, which can lead to significant morbidity if untreated.
