Anti-Tissue Transglutaminase (tTG) Antibodies Also Found in Inflammatory Bowel Disease

Clin Chem Lab Med. 2004;42(10):1092-7

Celiac.com 01/22/2005 - A study by Italian researchers has found that anti-tissue transglutaminase (tTG) antibodies, once considered to be identical to anti-endomysial antibodies (EMA) in celiac disease, can also be found in patients with inflammatory bowel disease. The researchers looked at serum and intestinal tTG levels in 49 patients with Crohns disease, 29 patients with ulcerative colitis, 45 patients with celiac disease, 85 autoimmune patients as disease controls, and 58 volunteers as healthy controls. Additionally, Immunoglobulin A (IgA) anti-recombinant human tissue transglutaminase and anti-endomysial antibody detection in sera and fecal supernatants, along with adsorption of positive sera with recombinant human tissue transglutaminase, were performed on all patients.

The researchers detected an increase in tTG concentration in all patients with celiac disease, and also low positive values in those with Crohns disease and ulcerative colitis, however the EMA were only detected in those with celiac disease. According to the researchers, the "Data highlight that both circulating and intestinal anti-tissue transglutaminases are detectable in inflammatory bowel disease, and that they are related to disease activity. These features underline that, in addition to anti-tissue transglutaminase, an anti-endomysial antibody test is necessary in the diagnostic work-up of celiac sprue, especially in patients with known inflammatory bowel disease."

This study supports others that have found that the sole use of tTG to diagnose celiac disease may lead to misdiagnoses, and EMA testing must be performed to make an accurate celiac disease diagnosis.

Might want to look into a keto diet, I have UC on top of celiacs and keto is working great Yeah I have major nerve and brain issues with gluten, gluten ataxia with nerve issues and brain issues. Seems to cause my body to attack my brain and nerve system. My brain stumbles fogs, and starts looping, the confusion causes me to become really irritable, I call it going Mr Hyde. Like my mind will start looping constantly on thoughts and not move driving me literally mad, or it used to. Now days it is primary the numbness anger but the gut issues and sometimes random motor loss limit me motionless to the floor now days for the duration of the major anger effects. Used to be a lot more mental then painful gut. I did a mental trauma post on it on while back where I came out about all my mental issues with gluten.

^^^^^^ good info, tips and tricks^^^^^^^^^ yes, crumbs will make you sick. also, breathing flour/pancake mix, etc that is in the air because eventually, you're going to swallow some.

Hello I was diagnosed Dec 15 of last year and went totally gluten-free the next day. I actually got worse before I got better - it's a steep learning curve - but now, 4 1/2 months later I'm finally seeing improvement. Hang in there.

Called my GI doctor today to make sure he is going to look at my small intestine and do biopsy for Celiac for my EGD and he is. Thanks for the tip everyone about have to start eating gluten again. The office told me to break my gluten free diet and start eating gluten everyday until my EGD. Here's to being miserable again for a few weeks ???

I can completely relate! The horrible mental effects that I have been living with for years is the absolute worst side effect of eating gluten, HANDS DOWN. Worse than the endless tummy aches, worse than the constant diarrhea, worse than the week long migraines, worse than the daily fatigue and body pain.... I honestly though there was something seriously wrong with me and hated my life because of how I felt mentally. I always felt like I was drowning, not in control of my thoughts, trapped in some unexplained misery. My head was always so cloudy, and I was mad because I always felt so slow and stupid. I would feel so lethargic and sad and empty while at the same time be raging inside, wanting to rip out of my own skin. I was mean, terrible, would snap at the people closest to me for no good reason and just felt like I hated everyone and everything. Think of how crappy you feel when you have a terrible cold and flu - I felt that crappy, but mentally. Some days were really bad, some were mild. I always thought it was because I was getting a migraine, or because I had a migraine, or because I had just overcome a migraine, because I didn't sleep well, because....always a random reason to justify why we have all these weird unrelated symptoms before we get diagnosed. I'm happy to say that I have been gluten-free for about 2 months now and though I am not symptom free, the first thing that improved was my mood. I no longer feel foggy and miserable. For the first time in years, my head is clear, I can actually think, and I feel positive and like I am in control of what's going on in my head. I don't hate the world. I don't spend every day bawled up on the corner of the couch depressed and angry. The release of these horrible symptoms is enough to never make me want to cheat, no matter what I have to miss out on. So insane how a little minuscule amount of a stupid protein can wreck such havoc.
