Mortality in lupus nephritis.

The principal causes of death of 68 patients with lupus glomerulonephritis were reviewed. Renal failure (40%), vascular events (25%), and infections (16%) were the predominant causes. Diffuse proliferative glomerulonephritis was associated with an increased frequency of renal failure. A bimodal pattern of early deaths due to active lupus and sepsis and late deaths from vascular events was found superimposed on a constant rate of death from renal failure.
