Systemic lupus erythematosus (SLE), also called lupus, is an autoimmune disorder in which the body's immune system (the cells in the body that fight infection) incorrectly attack the
body's own tissues and organs, leading to inflammation and damage. Lupus most
commonly affects women of childbearing age but also occurs in children, adolescents,
and men. The cause of lupus is unknown, but it has been associated with genetic,
environmental, and infectious causes. The disorder may affect almost all organs
in the body, with the kidney being most commonly involved. The disorder may
be mild in some cases (for example, only involving the skin) and very severe
in other cases (affecting multiple organs, including the brain). The disease
course is characterized by flares (intervals of active
disease) and remissions (intervals of inactive disease).
The June 22/29, 2005, issue of JAMA includes an article
that describes the available treatments for the kidney disease associated
with lupus.
