 Attempts to modulate the immune response with regard to coeliac disease are mostly still in phase I of clinical testing; one agent (CCX282-B) has been evaluated in a phase II clinical trial on the basis of small-intestinal biopsies taken from people with coeliac disease before and after gluten exposure.Although popularly used as an alternative treatment for people with autism, there is no good evidence that a gluten-free diet is of benefit.In the subset of people who have gluten sensitivity there is limited evidence that suggests that a gluten free diet may improve some autistic behaviors.
