| Outline of Final Research Achievements |
In patients with systemic lupus erythematosus (SLE), neuropsychiatric manifestations (NPSLE) is a refractory disorder, because their disease-specific markers and treatment strategy are not well determined. The present study shows a certain subset of NPSLE, which has a link of cerebrospinal fluid (CSF)-autoantibodies, CSF-inflammatory mediators, and blood brain barrier (BBB) permeabilities. Especially, CSF-IL-6 concentration was elevated in association with anti-NR2 antibodies by BBB injury. Also, anti-U1RNP antibodies may activate IFN-α production intrathecally and up-regulate CSF-IL-6 in the presence of CSF-anti-NR2 antibodies. We can conclude that both anti-NR2 and U1RNP antibody detections in NPSLE may be useful not only for diagnosis, but also treatment decision in primary NPSLE patients.
