It was too bad that the audio phone signal was not very good on the recording--between that and the good doctor's accent I had to listen to a number of parts a few times to figure out what he was saying.

Dr. H was for a long time considered an "out there" maverick for claiming that for many gluten problems took the form of neurological problems rather than gastrointestinal ones, and that such neurological presenters often had a distinct genetic immunological profile. As more and more research has been done, notably in the US and Italy, though, a lot of his ideas seem to be being borne out (one is reminded to peruse JCCglutenfree's The Gluten File for a lot of the links to papers/studies on this).
