Thank you to all who responded. I am sorry this summary has taken so long.
I received a few responses

Two people wrote about giardia (parasite)

One person about celiac and lactose intolerance

I received a detailed response  on Diseases Which Resemble Celiac Disease,
taken from http://www.celiac.com/similar.html, although, not all the
diseases are discussed and I do not know if they resemble celiac disease
basd on gastro symptoms or biopsy results. I will have to look further.

If I discover anything interesting< I will post it to the group

Thanks to all
