Something about the focus on rituximab in the CFS world is confusing me. as this drug is meant to target B cells, in effect, killing them off, why arent other immunomodulator/suppresant drugs given a focus alongside this one. I have not been following research on this drug and CFS, so forgive me, but why this drug, and not even some of the other drugs that target b cells, either ant cd20 drugs, or ones that work in another mechanism. Some of the MS drugs seem to have a likelyhood of co -success with CFS, at least based on mechanism of action. Why rituximab?
