Systemic lupus erythematosus (SLE) is an autoimmune disease that leads to t
he formation and deposition of immune complexes throughout the body, which
are pathogenic for the disease. Different forms of glomerulonephritis can o
ccur in patients with SLE and can contribute significantly to the associate
d morbidity and, ultimately, mortality from the disease. Over the past two
decades, there have been significant strides in our understanding of the di
sease and in treatments that attempt to control the formation and depositio
n of anti-DNA auto-antibodies and immune complexes, as well as the subseque
nt inflammatory cascade mediated through various cellular and humoral pathw
ays leading to progressive renal damage and end-stage renal disease. In thi
s chapter, we review the current understanding of the pathogenesis and trea
tment of lupus nephritis in its various stages and discuss the experimental
and human data regarding some of the potential newer forms of therapy. We
discuss data regarding the use of steroids, azathioprine, cyclophosphamide,
cyclosporine A, mycophenolate mofetil, gammaglobulin, plasmapheresis, LJP
394, flaxseed oil, bindarit, anti-CD40 ligand, and CTLA4Ig.
