Nervous system involvement in systemic lupus erythematosus

Abstract

Gibson, T., and Myers, A. R. (1976).Annals of the Rheumatic Diseases, 35, 398-406. Nervous system involvement in systemic lupus erythematosus. In a retrospective analysis of 80 patients with systemic lupus erythematosus (SLE) seen over a 10-year period, 41 (51%) exhibited neurological manifestations. Nervous system involvement was characterized by a significantly greater involvement of black patients (P < 0·02), a higher incidence of renal failure after the first appearance of neurological features (P < 0·05), and a significantly worse 10-year survival rate (P < 0·05). Specific neurological investigations were generally unhelpful in diagnosis. The finding of hypoglycorrhachia in 4 patients was striking and may have pathogenetic significance. The lack of a specific diagnostic test for central nervous system involvement may have hindered recognition of a cerebral abscess in one patient. Treatment with massive doses of corticosteroids was not obviously more effective than treatment with smaller doses. Autopsy findings showed scattered small cerebral infarcts but vasculitis was apparent in only one case.
