These lesions were the result of endothelial cell prolifera-tion and at times were associated with localized fibrinoid changes in the glomerular basement membrane. At this stage of lupus nephritis the tubules, blood vessels, and interstitial tissue were usually normal. The early glomerular lesion was

Not only is this antibody a valuable asset for the diagnosis of systemic lupus erythematosus, but it may also contribute to its pathogenesis. Consistent with this view is that titer of anti-dsDNA antibody reflects the presence of lupus nephritis.

Lupus nephritis is a major contributor to morbidity and mortality in systemic lupus erythematosus, but little is known about the pathogenic processes that underlie the progressive decay in renal function. A common finding in lupus nephritis is thickening of glomerular basement membranes associated with immune complex deposition.
