Prognosis in systemic lupus erythematosus

Conclusions In SLE, morbidity is universal and fatality is significant. One cannot learn too much about the prognostic markers for this disorder. The identification by means of renal biopsy of subclasses of lupus nephritis spurred the development of new treatment regimens that have improved outcomes. While proliferative nephritis remains a marker of serious renal involvement, the newer indices that attempt to quantify the activity and chronicity of the renal lesion, as well as greater awareness of the importance of tubulointerstitial involvement and improvement in the amount of subendothelial electron-dense deposits with therapy, will likely permit further fine-tuning of the treatment of individual patients with lupus nephritis.Neuropsychiatric involvement in SLE is another major determinant of financial costs, morbidity and death. Unfortunately, our knowledge of the prognostic markers for this more heterogeneous group of manifestations is less advanced than for lupus renal involvement. Additional studies are needed urgently to determine the factors that predict the subsequent development of the different forms of neuropsychiatric lupus. The determinants will likely differ among the various forms of neuropsychiatric lupus, thereby permitting different preventative or treatment regimens to be developed.The role of social factors, particularly socioeconomic status, has attracted attention in the United States. The lessons are likely applicable elsewhere. Additional studies to identify social factors that can be modified may bring tangible benefits to SLE patients in this decade.Although not universally accepted, it does appear that as more SLE patients survive the acute disease, there is an inordinately high risk of developing vascular diseases, including coronary artery disease, stroke and peripheral vascular disease. As with neuropsychiatric lupus, the determinants may differ depending on the specific vascular disease. Better knowledge of these determinants will permit a further improvement in the overall prognosis for patients with SLE.
