Serum I-FABP as Marker for Enterocyte Damage in Celiac Disease

Celiac.com 03/22/2013 - Enterocyte damage is one of the common features of celiac disease, and often results in malabsorption. Presently, doctors don't know very much about the recovery of enterocyte damage and its clinical consequences. Serum intestinal fatty acid binding protein (I-FABP) is a marker that allows researchers to study enterocyte damage.

Photo: CC--KezzeA research team set out to determine the severity of enterocyte damage in adult-onset celiac disease, how it responds to a gluten-free diet, and the correlation among enterocyte damage, celiac disease autoantibodies and histological abnormalities during the course of disease.

The research team included M. P. M. Adriaanse, G. J. Tack, V. Lima Passos, J. G. M. C. Damoiseaux, M. W. J. Schreurs, K. van Wijck, R. G. Riedl, A. A. M. Masclee, W. A. Buurman, C. J. J. Mulder, and A. C. E. Vreugdenhil. They are affiliated with the Department of Paediatrics & Nutrition and Toxicology Research Institute Maastricht (NUTRIM) at Maastricht University Medical Centre in Maastricht, the Netherlands.

For their study, the team first determined I-FABP blood levels in 96 biopsy-proven adults with celiac disease, and in 69 patients following a gluten-free diet. They used 141 individuals with normal antitissue transglutaminase antibody (IgA-tTG) levels as a control group.

They found that levels of I-FABP were related to the degree of villous atrophy (Marsh grade) and IgA-tTG. Patients with untreated celiac disease showed higher I-FABP levels (median 691 pg/mL) compared with control subjects (median 178 pg/mL, P < 0.001) and correlated with Marsh grade (r = 0.265, P < 0.05) and IgA-tTG (r = 0.403, P < 0.01).

I-FABP blood levels in patients following a gluten-free diet dropped substantially, but not within the range found in control subjects, even though they showed normalization of IgA-tTG levels and Marsh grade. Celiac patients with elevated I-FABP levels who did not respond to gluten-free diet showed persistent histological abnormalities.

The team's main finding was that enterocyte damage, as assessed by serum I-FABP, correlates with the severity of villous atrophy in celiac disease at the time of diagnosis.

Even though enterocyte damage improves upon treatment with a gluten-free diet, the majority of patients still show substantial enterocyte damage despite the absence of villous atrophy and low IgA-tTG levels.

Thus, they conclude that elevated I-FABP levels that do not respond to a gluten-free diet likely point to histological abnormalities and warrant further evaluation.

It would be interesting to repeat this study with the addition of a probiotic combined with a gluten-free diet compared to gluten-free diet alone.

It is likely that they are not studying the fact that all grains have gluten in them. Does not matter the type of grain for the most part.

Over the last 1.5 years I have had a rash that will not go away. The rash is around the neck, hairline on the front of my head, the back of my scalp, elbows, knees, shins, parts of my ankle, and buttock. The rash seem to get very itchy during the evening. I did have a skin biopsy completed and blood tests last year and they came back negative. I was on oral steroids when I had the test would this possible skew the results? Also its seems the body parts that are exposed to the sun seem to have the rash. Some Pictures http://s1084.photobucket.com/user/Richard_Brandys/library/

Yes the first has wheat gluten in the ingredients, the second via the wheat flour. Here in the UK manufacturers HAVE to highlight gluten sources. Check the ingredients and if WHEAT, BARLEY, or RYE are mentioned *usually highlighted, italicised or underlined, then you will know there's gluten. Most of iceland's processed foods will probably be gluten filled to be honest. Any breadcrumbed or battered foods for instance. Ps, you and me both have another disease, the british one of apologising You don't need to, you're very welcome here and all of your questions are valid and understandable. It's going to get better

Hi, I am deeply sorry for posting on here again. As I am scheduled for an Endoscopy on the 9th May, I wanted to make sure that my gluten intake is being kept the same. I was wondering if the ingredients to these products contain gluten even though dextrose is in one of them? http://groceries.iceland.co.uk/iceland-32-breaded-chicken-nuggets-448g/p/52275 Chicken Breast Fillet (60%), Water, Wheat Flour, Breadcrumbs (Wheat Flour, Dextrose, Salt, Yeast), Rapeseed Oil, Salt, Wheat Gluten, Sugar, Yeast Extract, Garlic Powder, Onion Powder, White Pepper, Dried Sage. http://groceries.iceland.co.uk/iceland-10-breaded-chicken-burgers-550g/p/52276 Chicken Breast Fillet (60%), Water, Wheat Flour, Breadcrumbs (Wheat Flour, Dextrose, Salt, Yeast), Rapeseed Oil, Salt, Wheat Gluten, Sugar, Yeast Extract, Garlic Powder, Onion Powder, White Pepper, Dried Sage. Thank you for all your help so far,

JMG got it down pretty much, the painful and gluten effects from eating it should clear up in a month, damage symptoms you might notice some differences as early as 2-4months but most do not noticed major improvements til about 6 months to a year. I have been gluten-free for over 3 years all my villi have healed according to the doctor on my last scope. It is very important to not cheat and avoid any kind of CC as it can set you back weeks or months. I would suggest a whole foods only diet for the first month or two, no dairy, simple stews, soups, etc. make for easy to digest and simple meals. Check out the 101 thread for some good information. PS a new combo crockpot, steamer, rice cooker combo and liners for a crock pot will be a life saver for making simple meals and easy clean ups. Quick cook microwave ware will also be handy making sure you have gluten-free cooked meals if you can not get new cookware immediately. I normally suggest cleaning out the entire house, scrubbing down knobs, handles, on the drawers, sink, fridge, cubbards etc. throw out condiment jars, checking ingredients on everything in the house including your hygiene and makeup. Putting in drawer organizers for new utensils, throwing out scratched glass, teflon, plastic, and steel cookware. Throwing out any Tupperware, and cutting boards, some utensils that can not be cleaned well. Some times you can save cast iron and stainless steel cook ware if you can run it in your ovens cleaning cycle over 600F. Gluten is a protein like blood if you can not clean a item where a CSI team will not find it give it up, it is not a germ that can be killed with disinfectant. I use freezer paper for clean prep surfaces, also makes clean up a breeze, I tend to use gloves alot also when fixing foods,

Hi Allie and welcome First off, I know 3 years was a long wait, but at 17 you've figured out celiac way before many people do. That should make a big impact on minimising its effects and helping you with the diet, so, bizarrely enough, congratulations! A lot of good advice has been brought together in this thread: Don't worry that your symptoms are bad now. As you follow the diet your body will begin healing itself and you're still very young so hopefully this will go really smoothly. Think in terms of the next 6 months rather than weeks however, recovery will likely take a little time. Eat as healthily as you can, lots of whole foods and try to avoid the gluten free processed substitutes as your digestive system needs all the help it can get at this moment. You may want to avoid dairy as well for now and think about reintroducing it later. This site has been really helpful to me and others. I hope you find it just as useful. Best of luck! ps, your increased reaction to gluten during the challenge phase was perfectly normal. Many find that reintroducing it much worse than the initial affects and take some time to get over the challenge. That's why you'll see lots of posts here urging folks to 'stay on gluten' till their testing is complete! PPS( ) Inasmuch as your post can convey emotion, your's seemed positive Stay that way! At times the diet can be a bit isolating and some friends and family may struggle to understand. I'm sure it will be difficult at times making good choices and staying vigilant when everyone around you doesn't have to think twice. Stick with it, your health is paramount and it will be worthwhile. In time your good friends will get it and those that don't aren't worth worrying about. There are great foods you can eat and if not, learn to cook them yourself
