There are already clinics where they basically remove your immune system and give you a new one. If you don’t die in the process, you are likely to be cured of MS.
(Any existing damage will remain.)
Currently this is reserved for the most quickly progressing cases but if we can make this safer and cheaper, it might in future be applied as an early stage cure, so people can go on to live healthy lives.
That being said, Astra Zenecas approach does seem much safer, if it’s proven to be effective!
My mom passed from leukemia years ago. Or rather, from an infection as she was starting HSCT. I’m sure it’s safer than it was 30 years ago, but being without an immune system for a period of time really is still a last resort.
Of side effects of the process, or of opportunistic diseases during the transition?
A close family member suffers from MS and is on the more effective but less safe drugs available. They haven’t suffered a relapse since starting them four years ago, but they have been hospitalised twice as a result of side effects.
As we learn more about the relationship between the immune system and various seemingly unrelated diseases the research and understanding has massively increased over the last few years. I’m cautiously optimistic that better treatments aren’t far away. An ancestor was lobotomised for hysteria in the 1960s, before being diagnosed with MS.
