    TRANSGLUTAMINASES IN INFLAMMATION AND FIBROSIS OF THE GI TRACT AND LIVER


    Jefferson Adams

    Celiac.com 03/06/2009 - A report in the February 3rd issue of Digestive and Liver Disease highlights the present understanding of transglutaminase function in gastrointestinal and liver diseases and therapeutic strategies that target transglutaminase activities.

    A team of American and Italian researchers recently set out to review the current body of literature regarding transglutaminase function in gastrointestinal and liver diseases and therapeutic strategies that target transglutaminase activities. The research team was made up of doctors L. Elli, C.M. Bergamini, C.M. Bardella, and D. Schuppan.

    They are associated with one or more of the following: Center for Prevention and Diagnosis of Celiac Disease, Fondazione IRCCS Ospedale Maggiore Policlinico, Mangiagalli e Regina Elena, in Milan, Italy; the Department of Biochemistry, University of Ferrara, Via Luigi Borsari, Ferrara, Italy; the Department of Medical Sciences, University of Milan, Italy; and the Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, USA.

    Their report in the February issue of Digestive and Liver Disease highlights the present understanding of transglutaminase function in gastrointestinal and liver diseases and therapeutic strategies that target transglutaminase activities.

    Transglutaminases are a group of eight presently recognized calcium-dependent enzymes that act as catalysts to cross-link or deamidate proteins. They play a role in key biological functions such as the healing of wounds, the repair of damaged tissue, fibro-genesis, apoptosis, inflammation and management of the cell cycle. Thus, they play a role in numerous key patho-mechanisms of autoimmune, inflammatory and degenerative diseases, a number of which involve the gastrointestinal system.

    Transglutaminase 2 is of central importance, as it is crucial to the pathogenesis of celiac disease, and influences inflammation and fibro-genesis in inflammatory bowel and chronic liver disease.

    The recent review has implications for celiac disease, collagen, Crohn's disease, extra-cellular matrix, gliadin, inflammatory bowel disease; NFkB, and ulcerative colitis.

    In an attempt to determine the frequency of liver injury in adult coeliac disease (A.C.D.) the case records of 74 consecutive patients were examined. In 13 cases histological sections of the liver were available and in 5 of these there were signs of reactive hepatitis. Histological signs of distinct hepatic injury with cirrhosis and/or chronic active hepatitis were found in 7 other patients. In 5 of these serum-IgA was normal, whereas 16 out of 20 control patients with liver cirrhosis not associated with A.C.D. had raised serum-IgA. Serum-aspartate-aminotransferase and serum-alanine-aminotransferase were determined in 53 patients; 29 had raised concentrations. In 19 patients serum-aminotransferases were repeatedly determined before and during the dietary regimen and there was a significant reduction in enzyme concentrations during treatment. The median concentration of serum-alkaline-phosphatase was also reduced during treatment but not significantly. The histological evidence of liver injury in 16% and the abnormal liver-function tests in 39% of the patients indicate that hepatic injury is common in A.C.D. Since liver-function tests or liver biopsy specimens were available for only about two-thirds of the patients, liver damage in A.C.D. may be more common than indicated by these results. The effect of a gluten-free diet on aminotransferase concentrations indicates that the liver injury may be reversible and suggests that in some A.C.D. patients, progressive liver damage may be prevented by suitable treatment. Since A.C.D. is not always recognized, the diagnosis should be considered in patients with liver disease of unknown aetiology.

    Celiac.com 06/08/2005 – Australian researchers searched Medline and other references for cases of celiac disease and liver disease from 1966 to 2003. They found six studies that reported liver biochemistry in 591 celiac disease patients—out of which a full 248 had abnormal results—the most common of which being elevated transaminases. In 115 of 130 patients with elevated transaminases a gluten-free diet returned the levels to normal.
    The researchers found a much greater association of primary biliary cirrhosis and advanced liver disease in those with celiac disease than expected, and conclude that abnormal liver biochemistry is frequent in untreated celiac disease—and those with it should undergo tissue transglutaminase screening for celiac disease—which could lead to a proper diagnosis in many cases. In rare cases celiac-induced hepatitis may progress to end-stage liver disease.

    Celiac.com 06/22/10 - A research team set out to examine gut diseases and prognostic factors tied to non-cirrhotic intrahepatic portal hypertension. The team included C. E. Eapen, Peter Nightingale, Stefan G. Hubscher, Peter J. Lane, Timothy Plant, Dimitris Velissaris, and Elwyn Elias.
    The prognosis for non-cirrhotic intrahepatic portal hypertension (NCIPH) is usually benign. Assessment of a cohort study followed-up at a tertiary referral center leads the research team to hypothesize that gut-derived prothrombotic factors may contribute to the pathogenesis and prognosis of NCIPH.
    The team conducted a retrospective analysis of celiac disease indicators in 34 NCIPH patients. They also looked for associated gut conditions.
    Survival rates for transplant-free NCIPH patients from first presentation of symptoms was 94% (SE: 4.2%) at one year, 84% (6.6%) at 5-years, and 69% (9.8%) at 10-years.
    Sixteen of the patients (53%) showed decompensated liver disease. Three (9%) patients suffered ulcerative colitis, while five of 31 (16%) had clinical celiac disease. Kaplan–Meier analysis showed that celiac disease patients was a predictor of lower transplant-free survival (p = 0.018) rates.
    Multivariable Cox regression analysis revealed that other predictors of reduced transplant-free survival included older age at first NCIPH presentation, hepatic encephalopathy, and portal vein thrombosis.
    Just over one-third (36%) of patients with NCIPH showed substantially higher initial serum IgA anticardiolipin antibody (CLPA), compared to 6% with Budd–Chiari syndrome (p = 0.032 using Fisher’s exact test) and no celiac disease patients without concomitant liver disease (p = 0.007).
    In addition to noting factors affecting prognosis, the team found that just over half (53%) of NCIPH cases resulted in liver failure.

    Celiac.com 03/16/2015 - Researchers don't really have too much data on celiac disease in patients with cryptogenic cirrhosis or idiopathic noncirrhotic intrahepatic portal hypertension (NCIPH).
    In India, a research team recently set out to look for celiac disease in patients with portal hypertension. The research team included Rakhi Maiwall, Ashish Goel, Anna B. Pulimood, Sudhir Babji, J. Sophia, Chaya Prasad, K. A. Balasubramanian, Banumathi Ramakrishna, Susy Kurian, G. and John Fletcher.
    For their study, the team enrolled 61 consecutive patients with portal hypertension having cryptogenic chronic liver disease, including 14 with NCIPH, along with 59 patients with hepatitis B- or C-related cirrhosis as control subjects.
    They looked at tissue transglutaminase (tTG) antibody and duodenal histology in study patients. They found six cases of celiac disease, including two NCIPH patients, while they found none in control subjects.
    Duodenal biopsies for a significant percentage of the remaining study subjects showed villous atrophy, crypt hyperplasia, and lamina propria inflammation, not accompanied by raised intraepithelial lymphocytes (IELs), far more commonly than in controls.
    Study subjects with portal hypertension having cryptogenic chronic liver disease showed an unexpectedly high rate of tTG antibody positivity (66%), as compared to 29% in controls (p-value < 0.001), which could indicate false-positive test result.
    This study showed that 10% of patients with unexplained portal hypertension (cryptogenic chronic liver disease) had associated celiac disease. In addition, an unexplained enteropathy was seen in a significant proportion of study patients, more so in patients with cryptogenic chronic liver disease. This finding warrants further investigation.

    Celiac.com 04/24/2018 - Did you know in 2017 alone, the United States had OVER TENS OF THOUSANDS of people evacuate their homes due to natural disasters such as fires, floods, hurricanes, tornadoes and tsunamis? Most evacuation sites are not equipped to feed your family the safe gluten free foods that are required to stay healthy.  Are you prepared in case of an emergency? Do you have your Gluten Free Emergency Food Bag ready to grab and go?  
    I have already lived through two natural disasters. Neither of which I ever want to experience again, but they taught me a very valuable lesson, which is why I created a Gluten Free Emergency Food Bag (see link below). Here’s my story. If you’ve ever lived in or visited the Los Angeles area, you’re probably familiar with the Santa Ana winds and how bitter sweet they are. Sweet for cleaning the air and leaving the skies a brilliant crystal blue, and bitter for the power outages and potential brush fires that might ensue.  It was one of those bitter nights where the Santa Ana winds were howling, and we had subsequently lost our power. We had to drive over an hour just to find a restaurant so we could eat dinner. I remember vividly seeing the glow of a brush fire on the upper hillside of the San Gabriel Mountains, a good distance from our neighborhood. I really didn’t think much of it, given that it seemed so far from where we lived, and I was hungry! After we ate, we headed back home to a very dark house and called it a night. 
    That’s where the story takes a dangerous turn….about 3:15am. I awoke to the TV blaring loudly, along with the lights shining brightly. Our power was back on! I proceeded to walk throughout the house turning everything off at exactly the same time our neighbor, who was told to evacuate our street, saw me through our window, assuming I knew that our hillside was ablaze with flames. Flames that were shooting 50 feet into the air. I went back to bed and fell fast asleep. The fire department was assured we had left because our house was dark and quiet again. Two hours had passed.  I suddenly awoke to screams coming from a family member yelling, “fire, fire, fire”! Flames were shooting straight up into the sky, just blocks from our house. We lived on a private drive with only one way in and one way out.  The entrance to our street was full of smoke and the fire fighters were doing their best to save our neighbors homes. We literally had enough time to grab our dogs, pile into the car, and speed to safety. As we were coming down our street, fire trucks passed us with sirens blaring, and I wondered if I would ever see my house and our possessions ever again. Where do we go? Who do we turn to? Are shelters a safe option? 
    When our daughter was almost three years old, we left the West Coast and relocated to Northern Illinois. A place where severe weather is a common occurrence. Since the age of two, I noticed that my daughter appeared gaunt, had an incredibly distended belly, along with gas, stomach pain, low weight, slow growth, unusual looking stool, and a dislike for pizza, hotdog buns, crackers, Toast, etc. The phone call from our doctor overwhelmed me.  She was diagnosed with Celiac Disease. I broke down into tears sobbing. What am I going to feed my child? Gluten is everywhere.
    After being scoped at Children's Hospital of Chicago, and my daughters Celiac Disease officially confirmed, I worried about her getting all the nutrients her under nourished body so desperately needed. I already knew she had a peanut allergy from blood tests, but just assumed she would be safe with other nuts. I was so horribly wrong. After feeding her a small bite of a pistachio, which she immediately spit out, nuts would become her enemy. Her anaphylactic reaction came within minutes of taking a bite of that pistachio. She was complaining of horrible stomach cramps when the vomiting set in. She then went limp and starting welting. We called 911.
    Now we never leave home without our Epipens and our gluten free food supplies. We analyze every food label. We are hyper vigilant about cross contamination. We are constantly looking for welts and praying for no stomach pain. We are always prepared and on guard. It's just what we do now. Anything to protect our child, our love...like so many other parents out there have to do every moment of ever day!  
    Then, my second brush with a natural disaster happened, without any notice, leaving us once again scrambling to find a safe place to shelter. It was a warm and muggy summer morning, and my husband was away on a business trip leaving my young daughter and me to enjoy our summer day. Our Severe Weather Alert Radio was going off, again, as I continued getting our daughter ready for gymnastics.  Having gotten used to the (what seemed to be daily) “Severe Thunderstorm warning,” I didn’t pay much attention to it. I continued downstairs with my daughter and our dog, when I caught a glimpse out the window of an incredibly black looking cloud. By the time I got downstairs, I saw the cover to our grill literally shoot straight up into the air. Because we didn’t have a fenced in yard, I quickly ran outside and chased the cover, when subsequently, I saw my neighbor’s lawn furniture blow pass me. I quickly realized I made a big mistake going outside. As I ran back inside, I heard debris hitting the front of our home.  Our dog was the first one to the basement door! As we sat huddled in the dark corner of our basement, I was once again thinking where are we going to go if our house is destroyed. I was not prepared, and I should have been. I should have learned my lesson the first time. Once the storm passed, we quickly realized we were without power and most of our trees were destroyed. We were lucky that our house had minimal damage, but that wasn’t true for most of the area surrounding us.  We were without power for five days. We lost most of our food - our gluten free food.
    That is when I knew we had to be prepared. No more winging it. We couldn’t take a chance like that ever again. We were “lucky” one too many times. We were very fortunate that we did not lose our home to the Los Angeles wildfire, and only had minimal damage from the severe storm which hit our home in Illinois.
      
    In 2017 alone, FEMA (Federal Emergency Management Agency) had 137 natural disasters declared within the United States. According to FEMA, around 50% of the United States population isn’t prepared for a natural disaster. These disasters can happen anywhere, anytime and some without notice. It’s hard enough being a parent, let alone being a parent of a gluten free family member. Now, add a natural disaster on top of that. Are you prepared?

    Celiac.com 04/23/2018 - A team of researchers recently set out to learn whether celiac disease patients commonly suffer cognitive impairment at the time they are diagnosed, and to compare their cognitive performance with non-celiac subjects with similar chronic symptoms and to a group of healthy control subjects.
    The research team included G Longarini, P Richly, MP Temprano, AF Costa, H Vázquez, ML Moreno, S Niveloni, P López, E Smecuol, R Mazure, A González, E Mauriño, and JC Bai. They are variously associated with the Small Bowel Section, Department of Medicine, Dr. C. Bonorino Udaondo Gastroenterology Hospital; Neurocience Cognitive and Traslational Institute (INECO), Favaloro Fundation, CONICET, Buenos Aires; the Brain Health Center (CESAL), Quilmes, Argentina; the Research Council, MSAL, CABA; and with the Research Institute, School of Medicine, Universidad del Salvador.
    The team enrolled fifty adults with symptoms and indications of celiac disease in a prospective cohort without regard to the final diagnosis.  At baseline, all individuals underwent cognitive functional and psychological evaluation. The team then compared celiac disease patients with subjects without celiac disease, and with healthy controls matched by sex, age, and education.
    Celiac disease patients had similar cognitive performance and anxiety, but no significant differences in depression scores compared with disease controls.
    A total of thirty-three subjects were diagnosed with celiac disease. Compared with the 26 healthy control subjects, the 17 celiac disease subjects, and the 17 disease control subjects, who mostly had irritable bowel syndrome, showed impaired cognitive performance (P=0.02 and P=0.04, respectively), functional impairment (P<0.01), and higher depression (P<0.01). 
    From their data, the team noted that any abnormal cognitive functions they saw in adults with newly diagnosed celiac disease did not seem not to be a result of the disease itself. 
    Their results indicate that cognitive dysfunction in celiac patients could be related to long-term symptoms from chronic disease, in general.

    Celiac.com 04/21/2018 - Dear Friends and Readers,
    I have been writing articles for Scott Adams since the 2002 Summer Issue of the Scott-Free Press. The Scott-Free Press evolved into the Journal of Gluten Sensitivity. I felt honored when Scott asked me ten years ago to contribute to his quarterly journal and it's been a privilege to write articles for his publication ever since.
    Due to personal health reasons and restrictions, I find that I need to retire. My husband and I can no longer travel the country speaking at conferences and to support groups (which we dearly loved to do) nor can I commit to writing more books, articles, or menus. Consequently, I will no longer be contributing articles to the Journal of Gluten Sensitivity. 
    My following books will still be available at Amazon.com:
    Gluten-free Cooking for Dummies Student's Vegetarian Cookbook for Dummies Wheat-free Gluten-free Dessert Cookbook Wheat-free Gluten-free Reduced Calorie Cookbook Wheat-free Gluten-free Cookbook for Kids and Busy Adults (revised version) My first book was published in 1996. My journey since then has been incredible. I have met so many in the celiac community and I feel blessed to be able to call you friends. Many of you have told me that I helped to change your life – let me assure you that your kind words, your phone calls, your thoughtful notes, and your feedback throughout the years have had a vital impact on my life, too. Thank you for all of your support through these years.

    Celiac.com 04/20/2018 - A digital media company and a label data company are teaming up to help major manufacturers target, reach and convert their desired shoppers based on dietary needs, such as gluten-free diet. The deal could bring synergy in emerging markets such as the gluten-free and allergen-free markets, which represent major growth sectors in the global food industry. 
    Under the deal, personalized digital media company Catalina will be joining forces with Label Insight. Catalina uses consumer purchases data to target shoppers on a personal base, while Label Insight works with major companies like Kellogg, Betty Crocker, and Pepsi to provide insight on food label data to government, retailers, manufacturers and app developers.
    "Brands with very specific product benefits, gluten-free for example, require precise targeting to efficiently reach and convert their desired shoppers,” says Todd Morris, President of Catalina's Go-to-Market organization, adding that “Catalina offers the only purchase-based targeting solution with this capability.” 
    Label Insight’s clients include food and beverage giants such as Unilever, Ben & Jerry's, Lipton and Hellman’s. Label Insight technology has helped the Food and Drug Administration (FDA) build the sector’s very first scientifically accurate database of food ingredients, health attributes and claims.
    Morris says the joint partnership will allow Catalina to “enhance our dataset and further increase our ability to target shoppers who are currently buying - or have shown intent to buy - in these emerging categories,” including gluten-free, allergen-free, and other free-from foods.
    The deal will likely make for easier, more precise targeting of goods to consumers, and thus provide benefits for manufacturers and retailers looking to better serve their retail food customers, especially in specialty areas like gluten-free and allergen-free foods.

    Celiac.com 04/19/2018 - Previous genome and linkage studies indicate the existence of a new disease triggering mechanism that involves amino acid metabolism and nutrient sensing signaling pathways. In an effort to determine if amino acids might play a role in the development of celiac disease, a team of researchers recently set out to investigate if plasma amino acid levels differed among children with celiac disease compared with a control group.
     
    The research team included Åsa Torinsson Naluai, Ladan Saadat Vafa, Audur H. Gudjonsdottir, Henrik Arnell, Lars Browaldh, and Daniel Agardh. They are variously affiliated with the Institute of Biomedicine, Department of Microbiology & Immunology, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden; the Institute of Clinical Sciences, Sahlgrenska Academy at the University of Gothenburg, Gothenburg, Sweden; the Department of Pediatric Gastroenterology, Hepatology and Nutrition, Karolinska University Hospital and Division of Pediatrics, CLINTEC, Karolinska Institute, Stockholm, Sweden; the Department of Clinical Science and Education, Karolinska Institute, Sodersjukhuset, Stockholm, Sweden; the Department of Mathematical Sciences, Chalmers University of Technology, Gothenburg, Sweden; the Diabetes & Celiac Disease Unit, Department of Clinical Sciences, Lund University, Malmö, Sweden; and with the Nathan S Kline Institute in the U.S.A.
    First, the team used liquid chromatography-tandem mass spectrometry (LC/MS) to analyze amino acid levels in fasting plasma samples from 141 children with celiac disease and 129 non-celiac disease controls. They then crafted a general linear model using age and experimental effects as covariates to compare amino acid levels between children with celiac disease and non-celiac control subjects.
    Compared with the control group, seven out of twenty-three children with celiac disease showed elevated levels of the the following amino acids: tryptophan; taurine; glutamic acid; proline; ornithine; alanine; and methionine.
    The significance of the individual amino acids do not survive multiple correction, however, multivariate analyses of the amino acid profile showed significantly altered amino acid levels in children with celiac disease overall and after correction for age, sex and experimental effects.
    This study shows that amino acids can influence inflammation and may play a role in the development of celiac disease.
