Is a persistent adenovirus infection involved in coeliac disease?
Recent evidence has implicated adenovirus 12 in the aetiology of coeliac disease so that persistent infection by this virus must be considered. We have undertaken a search for adenovirus DNA in duodenal biopsy samples from a total of 26 coeliac and non-coeliac patients. We could find no evidence of persistent virus DNA by Southern blot techniques even under conditions which approach a sensitivity of one copy of virus genome per cell, and use either adenovirus 12 or 41 DNA.
