<<Disclaimer: Verify this information before applying it to your situation.>> Hi All-- Brief background: I've been blood tested for CD three times with negative results on the antibodies, but positive on the malabsorption; two biopsies negative for sprue, but showing "minimal flattening." I've been gf for 8 weeks now - trips to the ER for pain and vomiting have stopped, and my liver enzymes have returned to nearly normal. My GI told me that he recommended staying on the gf diet, though he can't give a definite dx of celiac. He also said that there is a bacteria that can cause this "minimal flattening" of the villa, usually found in diabetics or those who have had gastrointestinal surgery - the bacteria travels to the usually sterile small intestine. There is a breath test to detect this bacteria. Does anyone know what bacteria he may be referring to? I tested negative via biopsy for H. pylori, so I don't think this is what he's thinking of (unless he has forgotten that I tested negative for H. pylori). My doc is 70 miles away and I correspond with his nurse. I've asked her what this bacteria is, but she hasn't replied yet. Thanks for any thoughts anyone might have...I'm stumped. Cheers, Ayn
