Oligoclonal IgG bands (OCGB) are characteristic of multiple sclerosis (MS). Most patients show OCGB exclusively in cerebrospinal fluid (CSF). Others have serum bands with additional ones in CSF. Moreover, IgM bands against myelin lipids (LS-OCMB) associate with aggressive relapsing-remitting MS (RRMS). We studied oligoclonal bands in 424 MS patients. Most primary progressive (PPMS) patients showed serum OCGB with additional bands in CSF Conversely, most RRMS and secondary progressive (SPMS) patients showed OCGB exclusively in CSF (p<0.0001). Moreover, no PPMS patient presented LS-OCMB, while 31% of RRMS and 60% of SPMS groups showed these antibodies (p<0.0001). This suggests heterogeneous autoimmune mechanisms in MS.
