Refractory Celiac Disease: Unlocking the Origin of Aberrant Lymphocytes

Celiac.com 10/25/2012 - Abnormal intraepithelial lymphocytes (IELs) are the main feature of refractory celiac disease type II (RCDII). However, researchers still don't know exactly how these abnormal IELs originate.

The pair were Victor F. Zevallos, and Detlef Schuppan, of the center for Molecular and Translational Medicine, Department of Medicine I at the University Medical Center of Johannes Gutenberg University Mainz, in Mainz, Germany.

Their commentary focuses on efforts by a separate research team, Schmitz, et al., which had already used a broad spectrum of cell specific markers, RNA array and immunological techniques, to explore abnormal IEL cell lines from four RCDII patients, and compare them with IELs from the fetal intestine, the intestine of children and adults and the thymus.

IELs are highly varied lymphocytes cells with innate and adaptive features that live in the small and large intestine. IELs play an important role in maintaining gut tolerance to common food antigens versus defense against pathogens.

A number of nutritional factors influence the development and spread of IELs, especially vitamins and their active metabolites, such as retinoic acid, and phytochemicals such as ligands of the aryl hydrocarbon receptor from cruciferous vegetables.

However, when IELs activate and expand uncontrollably in response to chronic inflammatory conditions in the gut, they trigger mucosal damage, which can lead to celiac disease, and in some cases, to malignant cancers.

Up to 5% of people with celiac disease, especially those who are over fifty years old when diagnosed, continue to suffer from clinical symptoms and villous atrophy even when following a gluten-free diet.

After excluding ongoing gluten consumption and other potential underlying diseases, all four patients studied by Schmitz could be diagnosed with RCD, which is classically classified as type I or type II, based on the histological co-expression of CD3 and CD8 in RCDI, or absence of such co-expression in RCDII.

They may be eating other grains that have a type of gluten in ithem. I can't eat corn and such things myself.

Abnormal IELs appeared on my lips about one year before clinical symptoms of celiac disease. The dermatologist called them Fordice spots. She had no idea that they might be related to celiac disease.

Hi! My daughter is 19 was diagnosed at age 16. It took about 12-18 month s for her to fully heal from the damage and feel "normal" again. Also because of the damage done she had reactions to dairy, so you may want to try no or minimum dairy until youre fully healed. Just a suggestion. Hope you start feeling well soon!

Hi yall! New to this blog, but really glad it exists because I have lots of questions. First off, I'm Allie! I'm 17 and newly diagnosed Celiac after about 3 years of searching for answers. I initially went gluten-free on the recommendation of a friend, I felt better in about a month and then my pediatric gastroenterologist had me do the gluten challenge, and my symptoms were the worst they have ever been, and ones I barely noticed before became very present. I did the biopsy and was diagnosed, it's been about 2 weeks and my symptoms are still pretty bad, although my diet has no known sources of gluten or cross contamination. Wondering if anyone has any input on healing post gluten challenge, any tips or how long it took for you would be quite helpful! Thanks

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.
