Fig. 1From: BAFF Index and CXCL13 levels in the cerebrospinal fluid associate respectively with intrathecal IgG synthesis and cortical atrophy in multiple sclerosis at clinical onsetIgG and cytokine concentrations in the CSF. IgG Loc expressed in mg/dL (a), CSF CXCL13 and IL-21 concentrations (pg/mL; b, c), and BAFF Index values (d) in HC and CIS/eRRMS with (IgGOB+) or without (IgGOB−) intrathecal synthesis of IgG oligoclonal bands. IgGOB+ patients had increased CXCL13, normal IL-21, and decreased BAFF Index compared to HC and IgGOB− patients. Only significant comparison is indicated. Abbreviations: HC healthy controls, CIS/eRRMS CIS suggestive of MS or early RRMS, LP lumbar puncture, n.a. not applicable, CSF cerebrospinal fluid, S serum. IgGOB+: patients with IgG oligoclonal bands in the CSF; IgGOB−: patients without IgG oligoclonal bands in the CSFBack to article page
