Onset of Gluten Intolerance Related to a Virus?

This article from Finland is interesting. "Recent research findings indicate a possible connection between virus infections, the immune system and the onset of gluten intolerance, also known as coeliac disease."

I watched a child regress into autism (and gluten intolerance) following a chicken pox vaccine. I've always thought there was a relationship between the two. I wonder if the sore throat thing that we have a lot is related to chicken pox, and the doctor says that my theory may be right, but there's no way to test for it.
