your right, Radeck. The numbers aren't there.
And Lew, I wasn't putting this up to freak you out...seriously! We may learn in the future that what you did prior to stenting with tysabri was the right thing to do! I've talked to Dr. Cooke and Marie about this, and someday there will be a perfect protocol involving immune intervention, stenting and follow up care. We don't have it yet. In any event, now that your perfusion time and mean transit time have improved with better venous flow, I'm sure there are no worries.
I'm really more commenting on the fact that I haven't seen any medical research as to WHY PML occurs in MS brains. What's the mechanism of action? Why the brain? That's all.
Just saw Sarah's post...thanks for the clarification! It's just immune- as seen in HIV...nevermind!
