Hi, All - I have anti-MAG antibodies, which cause peripheral neuropathy and nerve entrapment. I had a rituxan treatment two years ago that was very effective - until recently. I am told this happens and that some people end up just getting these treatments every six months for years. I decided to get another treatment. However, I can't find any information about the long-term detrimental effects of repeated treatments. Are there none? I would think that wiping out one's B-cells on a regular basis might have negative effects. Anyone know about this subject or where I could go to find out more? Thanks!
