Doctors say a stem cell transplant could be a "game changer" for many patients with multiple sclerosis.
Louise Willetts, 36, from Rotherham, is now symptom-free and told me: "It feels like a miracle." A total of 100,000 people in the UK have MS, which attacks nerves in the brain and spinal cord.
Prof Richard Burt, lead investigator, Northwestern University Chicago, told me: "The data is stunningly in favour of transplant against the best available drugs - the neurological community has been sceptical about this treatment, but these results will change that." Prof John Snowden, haematologist and director of blood and bone marrow transplantation at Sheffield's Royal Hallamshire Hospital, told me: "We are thrilled with the results - they are a game changer for patients with drug resistant and disabling multiple sclerosis".
Prof Basil Sharrack, neurologist and director of MS research at Royal Hallamshire Hospital, told me: "This is interim analysis, but with that caveat, this is the best result I have seen in any trial for multiple sclerosis." "The worst time was not being able to get out of bed because I had no stability in my body - I struggled to walk and even spent time in a wheelchair.
Dr Susan Kohlhaas, director of research at the MS Society, said the stem cell transplant HSCT "will soon be recognised as an established treatment in England - and when that happens our priority will be making sure those who could benefit can actually get it".
