i dont even think they know how ritux works in RA or other autoimmune disorders but treatments with ritux isnt an issue. I believe dr k is doing extensive labs and looking closely at different aspects of the immune syste. I guess this is going to help him work out who is a candidate for treatment and who isnt as well as follow the progression of the disease alot closer with more advanced tests, he may them have answers has to how ritux is helping cfs/me which might direct him to the cause, maybe better treatments. Also dr k isnt just some doc the pulled out of a cornflakes packet, he seems very credentialled to do such work. there is no one doing this sort of work and it needs to be done.
