Hi habib,
I would not expect any doctor to be familiar with LDN for use in AS. While it is an older medication used to treat something else entirely, for use in treating autoimmune diseases, it is still experimental/trial stages. At this point, I don't think there have been any studies conducted for the purpose of treating the AS patient population, so it is still unknown for this and would be considered an 'off-label' use of the med, where it is being prescribed for some. At the low doses required, it is considered very safe.
I am sure if an LDN study for AS gets completed, one of our members will post it up for us in a heartbeat!
Take care,
mig
