Small Intestinal Intraepithelial Gamma/Delta T-Lymphocytes Occur Inversely to Lymphomas in Refractory Celiac Disease

Celiac.com 01/20/2009 - Refractory celiac disease is a serious condition that occurs when celiac symptoms and intestinal damage continue even when the patient consumes a gluten-free diet.

There are two types of refractory celiac disease (RCD). In RCD type I,  immuno-phenotype of intraepithelial lymphocytes (IELs) are normal and polyclonal, while RCD) type II, is noted for the presence of an abnormal intraepithelial lymphocyte (IEL) population (CD7+ CD3− CD4/8-cytoplasmic CD3+). More than half of people with this condition develop enteropathy-associated T-cell lymphoma (EATL), a rare but virulent form of cancer with high mortality rates.

A team of doctors recently set out to examine the relationship between lymphoma development and intraepithelial gamma/delta T-lymphocytes in the small intestine of patients with all types of celiac disease, as compared to the general population.

The team was made up of Wieke H.M. Verbeek, M.D., B. Mary E. von Blomberg, Ph.D., Petra E.T. Scholten, B.Sc., D. Joop Kuik, M.Sc., Chris J.J. Mulder, M.D. Ph.D., and Marco W.J. Schreurs, Ph.D., all from Amsterdam’s VU University Medical Center.

A certain type of IELs called TCRγ/δ+ IELs may play an important role in repairing mucosa, maintaining homeostasis, and guarding against tumor development. TCRγ/δ+ IELs in the human intestine have recently shown promise in the regulation of uncomplicated celiac disease.

In the study, the research team wanted to see if patients with RCD II had fewer TCRγ/δ+ IELs than either RDC I, or celiac disease, an thus provide a possible explanation for ongoing mucosal damage and inflammation, and the development of abnormal T cells that tend to morph into EATL.

The team used a method called multi-parameter flow cytometric immuno-phenotyping on IELs obtained from recent small bowel biopsy specimens from a fairly large, distinct celiac disease and control groups (N = 87).

Patients with RCD II showed a much lower ratio of TCRγ δ+ IELs compared to either RCD I or celiac disease patients. Whereas, patients with uncomplicated celiac disease showed significantly higher numbers of TCRγ δ+ IELs than were found in the control group. The results showed the relationship between TCRγ δ+ IELs and aberrant IELs to be negative. It is interesting to note that TCRγ δ+ IELs numbers do rise in RCD II patients after effective treatment.

The negative relationship between TCRγ δ+ and abnormal IELs, together with their known role in regulating uncomplicated celiac disease, suggests that TCRγ δ+ IELs may play a crucial role in helping the body to repair mucosa, maintain homeostasis and possibly even guard against tumor development.

These cells may serve as important markers, along with the abnormal T cells, to help distinguish between types of celiac disease, and to gage the effectiveness of treatment efforts.

So I've been gluten free for 6 months. I gave it up the day of my endoscopy and never looked back. I was a fairly silent Celiac. My blood work was always normal (never anemic, malnourished), I didn't have all the horrible symptoms that others do. I think I caught it early and that those things were definitely coming. Since going gluten-free I notice that my belly is better. I still have days where it's not great, but in the last month I've noticed that it's consistently pretty good. I don't hardly ever get stomach aches. I've lost 16 lbs and I'm never bloated. Those things are good. But, aside from that, I don't feel much different than I did before. I'm still tired a lot. But I have two kids under 4 and I run a non-profit. I have horrible anxiety and that's only increased since finding out about my Celiac (it's health anxiety and it freaked me out big time that I have an AI disorder). I feel like my complexion looks the same (never had an issue with that). I just read stories on here that talk about how the brain fog lifted quickly, or how people don't feel tired anymore, etc. I'm still a zombie sometimes. Has anyone else has this experience? Maybe my body was doing such a good job compensating for my Celiac that I wasn't really very symptomatic to begin with - and that the tiredness I feel isn't due to gluten. Oh, FYI, I had a full thyroid panel done in December and it was all normal.

Your daughter could have non celiac gluten sensitivity. That would correspond to negative celiac tests coupled with positive reaction to the gluten free diet. Whilst there are similarities to celiac presentation it appears that neuro symptoms are more common in ncgs patients. That seems to be the case for me anyway! The condition is as yet poorly understood but there is progress being made, check out a topic I just started on the pre diagnosis thread with some info and links. The remarks by umberto Volta in particular are just about the best summation I've yet seen on where the research is at. I will post a link later.

The gi may be able to see some signs of celiac visually but the chances are you will have to wait a couple of weeks for the biopsies before there's any confirmation. The damage to the villi is too small to detect with naked eye I think. as long as your eating some gluten each day you will have done all you can for a diagnosis. Not long now so go ahead and treat yourself to a nice cheesecake, fish and chips etc.

check out CoQ10, not related to celiac (as far as I know) but for balance issues.

remind your hubby, "if mama ain't happy, ain't nobody gonna be happy."
