    T-bet and pSTAT-1 Expression as New Markers of Celiac Disease Activity

    Reviewed and edited by a celiac disease expert.

    Celiac.com 10/28/2009 - Celiac disease is a T cell-mediated autoimmune disease, and a number of clinicians have described up-regulation of T-bet and phosphorylated signal transducers and activators of transcription (pSTAT)1, both of which are key transcription factors for the development of T helper type 1 (Th1) cells, in the mucosa of patients with untreated celiac disease.

    A team of researchers recently used transcription factor analysis to examine whether celiac patients up-regulate T-bet and pSTAT1 expressions in peripheral blood
    and whether such up-regulation may be associated with celiac disease activity.

    The research team was made up of G. Frisullo, V. Nociti, R. Iorio, A. K. Patanella, D. Plantone, A. Bianco, A. Marti, G. Cammarota, P. A.  Tonali, and A. P. Batocchi of the Department of Neurosciences at the Catholic University in Rome, Italy.

    The team used flow cytometry to analyze T-bet, pSTAT1 and pSTAT3 expression in CD4(+), CD8(+) T cells, CD19(+) B cells and monocytes from peripheral blood of 15 untreated and 15 treated celiac disease patients and 30 controls, and longitudinally in five celiac patients before and after dietary treatment.

    The team measured the results using enzyme-linked immunosorbent assay (ELISA), interferon (FN)-gamma, interleukin (IL)-17 and IL-10 production by peripheral blood mononuclear cell (PBMC) cultures.

    Patients with untreated celiac disease showed higher T-bet expression in CD4(+), CD8(+) T cells, CD19(+) B cells and monocytes and IFN-gamma production by PBMC, than either treated celiac patients or control subjects.

    CD4(+)T cells, B cells and monocytes from untreated celiac patients showed higher pSTAT1 expression than either treated celiac patients or controls. Only in monocytes from untreated patients showed increased pSTAT3 compared with treated celiac patients and controls. Data from longitudinal evaluation of transcription factors corroborated these findings.

    Flow cytometric analysis of pSTAT1 and T-bet protein expression in peripheral blood mononuclear cells could be useful and sensible markers in the follow-up of celiac disease patients to evaluate disease activity and response to dietary treatment.

    Being able to spot celiac disease early is key to achieving optimal outcomes for celiac patients. The development of simple, reliable, low-cost tests is key to that effort. Stay tuned for more developments regarding celiac disease testing, screening and diagnosis.

    In a video on celiac disease, the Dr. used "xonolin " to inhibit the absorption of gluten and yet allow vital nutrients into the cells. What are your comments on that?

    "xonolin" is a made-up word. 'Nuff said.

    Tara:

    I'm guessing 'xonolin' is a typo for 'Zonulin.' Zonulin is the molecule that helps form tight junctions between

    cells in the gut (and other places like skin). The tight junctions form a barrier between gut contents and the body. If the tight junctions are damaged (as happens in inflammation), the body is exposed to the gut contents.

    Celiac.com 01/11/2006 - There is an abundance of stories about people who begin a gluten-free diet, find that they feel better then decide they want a firm diagnosis of celiac disease. They are facing several problems. First, they may be gluten sensitive without the intestinal lesion of celiac disease. This is very likely since about twelve percent of the population is gluten sensitive, but only a little more than one percent of the general population has celiac disease. Another problem faced by gluten-free individuals who want a diagnosis is that it can take more than five years after returning to a regular gluten-containing diet before the characteristic damage of celiac disease can be seen on a biopsy1. Simply put, after beginning a gluten-free diet, only a positive biopsy is meaningful...

    Celiac.com 09/28/2007 - Celiac disease is one of the most common lifelong disorders in western countries. However, most cases in North America remain currently undiagnosed, mostly because they present unusual symptoms and because of the low number of doctors who have a sound awareness of celiac disease.
    In a large European survey, the ratio between diagnosed and undiagnosed cases, found by mass serological screening, was as high as 1 to 7 , an effect termed the ‘celiac iceberg’. In addition to having chronic symptoms that might otherwise respond to a gluten-free diet, undiagnosed patients are exposed to the risk of long-term complications of celiac disease, such as anemia, infertility, osteoporosis, or...

    Celiac.com 04/15/2009 - A recent clinical study has shown B vitamins to be beneficial for celiac sufferers following gluten-free diets. Vitamin deficiency and less than optimal health are common problems for people with celiac disease, even those who faithfully follow a gluten-free diet. Common problems associated with long-term celiac disease include general malaise, and less than optimal well-being.
    To better understand the benefits of supplemental doses of B vitamins for patients with celia disease, a team of researchers recently set out to evaluate the biochemical and clinical effects of B vitamin supplements in adults with long-term celiac disease. The research was made up of doctors C. Hallert, M. Svensson, J. Tholstrup, and B. Hultberg.
    The team assembled a group of 65 adults...

    Celiac.com 06/12/2009 - In a medical first, researchers at UCLA have made a connection between intestinal inflammation and systemic chromosome damage in mice, a discovery that may pave the way for early identification and treatment of human inflammatory disorders, some of which raise the risk for various kinds of cancer, according a study published in Cancer Research.
    Scientists discovered that local intestinal inflammation caused DNA damage to lymphocytes of the peripheral blood circulating throughout the body. So, contrary to conventional medical wisdom, chromosome damage is not limited to the immediate intestine, but involves body tissues far away from the actual inflammation. Their results showed single- and double-strand DNA breaks in the blood, and chromosome damage in peripheral...

      Celiac Maybe a Possibility?

      It seems you have proven that you cannot eat gluten. You've done what your doctors have not been able to do in 40 years. That's your low vitamin D, a common symptom with Celiac Disease. Zinc is also a common defiency. Its an antiviral. that's why zinc gluconate lozenges work against airborne viruses. Vitamin D and the Immune System+ ...

      Allergy Meds

      Hello, Target recently changed their branding on the Up & Up Loratadine and no long have it labeled gluten free. I've not been able to find any meds labeled gluten free for allergies. Some lists showed them but the the packaging isn't labeled. Wondering if anyone knows of or has a list that would be safe for Celiac kiddos.

      Weird Symptoms

      My mother also has celiac disease, and one of her symptoms for many years before her diagnosis was TMJ. I believe it took her many years on a gluten-free diet before this issue went away.

      Weird Symptoms

      Ear pain and ringing your entire life may or may not be TMJ related but could be something else. A good TMJ exam would be helpful to rule that out as a potential cause from a dentist who treats that. I have teens as well as adults of all ages who suffer from TMJ issues so it’s not a certain age when it shows up.
