Tysabri is a monoclonal antibody aimed at reducing the capabilities of the immune system, since if you believe that MS is a totally auto-immune disease, you also think that the body's immune system has gone haywire and is attacking the body itself.
Taking antibiotics does not effectively strengthen the immune system, but by Killing the CPn infection which causes so many diseases in genetically inclined people, it helps the immune system to work properly. For instance, I used also to have asthma and hayfever and very bad reactions to mosquito and cat flea bites. Now I don't have any of that: I still get bitten as much by mosquitoes, but I hardly notice, whereas before I would get great big weeping blisters on my arms or legs.
Do you know how many people tried your ABX regime yet?
How about their outcomes? Is there a quick overview available somewhere on the internet (like name, regime, duration of ABX intake, statechange)?
Do some people get worse on ABX?
Could you say something about an average improvement (like 1 EDSS or so)?
Lots of people are trying it and many end up writing to me, however, there has only been one small trial at Vanderbilt University, involving people with SPMS and this didn't use metronidazole. You can find it somewhere in the antibiotics section here. The best place to look is on CPn Help. You won't find a table, you will have to look through both Patient Stories and people's blogs. The people who immediately spring to mind, apart from myself, are Katman, who posts here as well, and LifeontheIce, who also posts in both places. Katman is married to a doctor, like me, and 'Ice is one.
I don't know of anyone who gets worse on ABX, unless they are non-compliant. It is possible that someone with RRMS might get a relapse in the early stage of treatment, especially if they get a bout of flu or something similar, but by no means everyone.
No worries about spelling my name wrong, the most usual mistake is just to leave the last letter off completely!
