Since the latest McDonald criteria were established, the prognostic role of cerebrospinal fluid (CSF) and visual evoked potentials (VEP) in CIS patients is still poorly defined. We conducted a monocentric investigation including patients with CIS in the time from 2010 to 2015. Follow-ups of 120 patients revealed that 42% converted to MS. CIS patients with positive oligoclonal bands (OCB) were more than twice as likely to convert to MS as OCB negative patients (hazard ratio = 2.6). The probability to develop MS was even higher when a quantitative intrathecal IgG synthesis was detected (hazard ratio = 3.8). In patients with OCB, VEP did not add further information concerning the conversion rate to MS. In patients with optic neuritis and negative OCB, a significantly higher rate converted to MS when VEP were delayed. In conclusion, the detection of an intrathecal IgG synthesis increases the conversion probability to MS. Pathological VEP can help to predict the conversion rate to MS in patients with optic neuritis without an intrathecal IgG synthesis.<\/jats:p>","DOI":"10.3390\/ijms18102061","type":"journal-article","created":{"date-parts":[[2017,9,27]],"date-time":"2017-09-27T10:52:25Z","timestamp":1506509545000},"page":"2061","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Clinically Isolated Syndrome According to McDonald 2010: Intrathecal IgG Synthesis Still Predictive for Conversion to Multiple Sclerosis"],"prefix":"10.3390","volume":"18","author":[{"given":"Philipp","family":"Schwenkenbecher","sequence":"first","affiliation":[{"name":"Clinical Neuroimmunology and Neurochemistry, Department of Neurology, Hannover Medical School, 30625 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anastasia","family":"Sarikidi","sequence":"additional","affiliation":[{"name":"Clinical Neuroimmunology and Neurochemistry, Department of Neurology, Hannover Medical School, 30625 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lena","family":"B\u00f6nig","sequence":"additional","affiliation":[{"name":"Clinical Neuroimmunology and Neurochemistry, Department of Neurology, Hannover Medical School, 30625 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulrich","family":"Wurster","sequence":"additional","affiliation":[{"name":"Clinical Neuroimmunology and Neurochemistry, Department of Neurology, Hannover Medical School, 30625 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Bronzlik","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Neuroradiology, Hannover Medical School, 30625 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8077-481X","authenticated-orcid":false,"given":"Kurt-Wolfram","family":"S\u00fchs","sequence":"additional","affiliation":[{"name":"Clinical Neuroimmunology and Neurochemistry, Department of Neurology, Hannover Medical School, 30625 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Refik","family":"Pul","sequence":"additional","affiliation":[{"name":"Clinical Neuroimmunology and Neurochemistry, Department of Neurology, Hannover Medical School, 30625 Hannover, Germany"},{"name":"Department of Neurology, University Clinic Essen, 45147 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2504-5398","authenticated-orcid":false,"given":"Martin","family":"Stangel","sequence":"additional","affiliation":[{"name":"Clinical Neuroimmunology and Neurochemistry, Department of Neurology, Hannover Medical School, 30625 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Skripuletz","sequence":"additional","affiliation":[{"name":"Clinical Neuroimmunology and Neurochemistry, Department of Neurology, Hannover Medical School, 30625 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,9,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"157","DOI":"10.1016\/S1474-4422(11)70274-5","article-title":"Clinically isolated syndromes","volume":"11","author":"Miller","year":"2012","journal-title":"Lancet Neurol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1221","DOI":"10.1016\/S0140-6736(02)08220-X","article-title":"Multiple sclerosis","volume":"359","author":"Compston","year":"2002","journal-title":"Lancet"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1013","DOI":"10.1177\/1352458514568827","article-title":"Conversion from clinically isolated syndrome to multiple sclerosis: A large multicentre study","volume":"21","author":"Kuhle","year":"2015","journal-title":"Mult.
