Yes, there are a couple of similar stories involving different approaches to boosting the immune system. The trial that I am watching involves provoking a strong TNF response which then results in a deletion of the autoimmune antibodies. If it works, it would be a cure. Immune boosting could potentially do the same thing - develop a strong TNF response - so it could be a cure also, possibly. It is interesting that children with immune disorders were prone to getting Crohn's as well. It lends credence to the possibility that other causes of immune insufficiency could be causes of Crohn's also. Vietnam vets with agent orange exposure would certainly fit that picture. So would chronic vitamin D deficiency - which depresses the immune system as well. You would almost wonder if regular use of aspirin could cause it - it is known to depress the immune system too. Makes me wonder about the "aspirin for blood thinning" idea that doctors suggest to some patients.
