Among the studies for blood tests, the highest sensitivity and specificity reported to date is testing circulating erythrocytes [9] (s=98.3%, e=89.5%). Also a good result was obtained using methylation patterns of circulating cell debris are specific for a number of conditions, including RRMS [ 10 ] There are ongoing efforts to be able to ...
Multiple sclerosis patients do not have it in blood, but it has been shown that 13% of tested patients reacted with the epitope AQPaa252-275. It is not known if these antibodies define distinct MS subsets, or are simply markers of astrocytic damage
Unusual types of MS have been described; these include Devic's disease, Balo concentric sclerosis, Schilder's diffuse sclerosis, and Marburg multiple sclerosis. There is debate on whether they are MS variants or different diseases. [31] Multiple sclerosis behaves differently in children, taking more time to reach the progressive stage. [5]
