Well this rings true to the flu type feelings I get. A good line of research to follow up methinks. Now where’s the substantial funding required?
I think people have to be aware that there are a number of gaps in the story.
Firstly, if a significant proportion of patients with ME had pathogenic autoantibodies one might expect there to be a noticeable response to rituximab and there was not at phase 3.
Perhaps most importantly there was no correlation between having autoantibodies and improving with rituximab at phase 2 either. Slightly more people with ME than normals seemed to have receptor autoantibodies but the difference was not big enough to suggest there was a causal link.
The immunoabsorption process removes all antibodies, not just the ones being tested for. So there is no evidence that it is the ones being tested for that are important.
We are let with the possibility that removing all antibodies and replacing them may make people with ME better for weeks or months. But it does not sound as if there was any clear pattern to this and there is no sham control. I think it is well worth while pursuing studies on immune cells but I am concerned about exposing people to potentially dangerous procedures without having a better rationale from the science.
