Prevalence and levels of autoantibodies in cerebrospinal fluid from patients with NPSLE and controls.

NPSLE = neuropsychiatric systemic lupus erythematosus; SLE-surgical = lupus patients who underwent elective surgery; SLE-septic meningitis = lupus patients with septic meningitis, Non-autoimmune = patients without autoimmune diseases. 1P<0.004 versus all SLE groups 2P<0.007 versus all SLE groups 3P<0.005 versus Central NPSLE and SLE-septic meningitis 4P = 0.006 versus SLE-septic meningitis 5P<0.05 versus all the other groups 6P<0.02 versus Central NPSLE 7The NMDAR antibody was measure in 34 SLE-CNS patients, 5 SLE-PNS, 12 SLE-surgical, 5 SLE-septic meningitis, and 25 Non-autoimmune patients. 8Autoantibodies levels represent the mean (±SD) among the patients in whom they were positive. The number of patients in each group for a particular antibody corresponds to the prevalences displayed in the upper panel.
