Autoimmunity and multiple sclerosis (MS)
| Evidence used to support the concept of autoimmunity in MS | Comments |
|---|---|
| Predominance of women affected, as in rheumatoid arthritis and systemic lupus erythematosus | Predominance of women also seen in non-autoimmune disorders such as migraine |
| Association of other autoimmune diseases in affected individuals and families | Not proven in large epidemiological studies of MS |
| Association with HLA haplotypes | The strongest HLA links are observed with hereditary haemochromatosis and narcolepsy, metabolic and neurodegenerative diseases respectively |
| Antimyelin antibodies in serum | Antimyelin antibodies can be detected in neurological disorders other than MS, and some antimyelin antibodies have a reparative function |
| Oligoclonal bands in cerebrospinal fluid | These bands are reported in other neurological diseases such as subacute sclerosing panencephalitis and neurosyphilis, conditions that are not autoimmune. Oligoclonal-band-negative cases of MS have been reported |
| Specific T-cell response identified during MS relapses | No T-cell response is unique or specific in MS |
| Partial therapeutic response of relapses to beta-interferons, glatiramer and other immunotherapies | Relapse prevention in MS may not translate into disability prevention. No immunotherapy has reduced long-term disability in MS |
