Is there a cure for celiac disease or dermatitis herpetiformis?
At this time there is no cure, and no hope for one any time soon. Once the disease has been triggered there is no way to turn it back off, though in the far future there might be hope for gene therapies or other mechanisms which could work; none of these are likely in the near future. However, while there is no actual cure, a gluten-free diet solves most of the problems associated with the disease.
