They are variously affiliated with the Department of Gastroenterology, Royal Hallamshire Hospital, Sheffield, U.K., the Academic Unit of Gastroenterology at the University of Sheffield in Sheffield, U.K., the Department of Medical Epidemiology and Biostatistics at Karolinska Institutet in Stockholm, Sweden, and the Department of Pediatrics of Örebro University Hospital at Örebro University in Örebro, Sweden.

    For their population-based cohort study, Dr. Kurien and colleagues analyzed data from Swedish National Patient Register between 1964 and 2009. 

    Their team identified all 42,539 patients diagnosed with type 1 diabetes before age 31 years of age. They used small intestinal biopsy reports showing villous atrophy to identify 947 type 1 diabetes patients with celiac disease between 1969 and 2008 (55.1% women; mean age of celiac disease diagnosis, 12 years).

    The research team then selected up to five type 1 diabetes patients as controls for each patient with both type 1 diabetes and celiac disease, and matched them for age, sex and birth year. They selected 4,584 in all; 54.5% women. They then used Cox regression analysis to calculate hazard ratios for future thyroid disease, with celiac disease as a time-dependent variable.

    They found that, over an average 13 years of follow-up, 90 patients in the group with both type 1 diabetes and celiac disease developed autoimmune thyroid disease (either hypothyroid or hyperthyroid); with an average age at thyroid disease diagnosis of 25 years old.

    In total, nearly 11% of patients in the type 1 diabetes and celiac disease group were diagnosed with thyroid disease at some stage of life vs. 7.2% of patients with type 1 diabetes without celiac disease.

    Patients with both type 1 diabetes and celiac disease faced an increased risk for hypothyreosis (HR = 1.66; 95% CI, 1.3-2.12) and hyperthyreosis (HR = 1.71; 95% CI, 0.95-3.11). The RR for thyroid disease in patients with both type 1 diabetes and celiac disease was 1.67 (95% CI, 1.32-2.11).

    The team found the highest risk levels for thyroid disease in patients from 1964-1975, which they attributed to poor screening for thyroid disease in type 1 diabetes patients during that time.

    The researchers noted that the highest risks in patients with more than ten years of celiac disease, which suggests that long-term double autoimmunity is a risk factor for autoimmune thyroid disease.

    Celiac.com 03/01/2010 - Common autoimmune disorders often coexist in the same subjects, and to cluster in families. A research team recently set out to quantify the risk of diagnosis of coexisting autoimmune diseases in more than 3000 index cases with clinically proven Graves' disease or Hashimoto's thyroiditis.
    The research team included Kristien Boelaert, PhD, Paul R. Newbya, Matthew J. Simmonds, PhD, Roger L. Holder, Jacqueline D. Carr-Smith, Joanne M. Heward, PhD, Nilusha Manjia, Amit Allahabadia, MD, Mary Armitage, DM, Krishna V. Chatterjee, PhD, John H. Lazarus, MD, Simon H. Pearce, PhD, Bijay Vaidya, PhD, Stephen C. Gough, PhD, and Jayne A. Franklyn, PhD.
    To establish the prevalence of coexisting autoimmune disorders, the team conducted a cross-sectional multi-center study of 3286 Caucasian subjects from UK hospital thyroid clinics. 2791 of those had Graves' disease, 495 had Hashimoto's thyroiditis.
    The team used a comprehensive questionnaire to obtain complete personal and parental history for each subject, including information on common autoimmune disorders, and parental history of hyperthyroidism or hypothyroidism.
    The frequency of other autoimmune disorders was 9.67% for patients with Graves' disease and 14.3% for those with Hashimoto's thyroiditis index cases (P=.005).
    Rheumatoid arthritis was the most common coexisting autoimmune disorder, striking 3.15% of patients with Graves' disease, and 4.24% of Hashimoto's thyroiditis cases.
    However, both conditions carried substantially higher relative risks for nearly all other autoimmune diseases (>10 for pernicious anemia, systemic lupus erythematosus, Addison's disease, celiac disease, and vitiligo).
    Cases of Graves' disease showed relative “clustering” among index subjects with parental hyperthyroidism, while cases of Hashimoto's thyroiditis showed relative “clustering” among index subjects with parental hypothyroidism.
    Relative risks for most other coexisting autoimmune disorders were markedly increased among parents of index cases.
    This study is one of the largest so far to quantify the risk of diagnosis of coexisting autoimmune diseases among more than 3000 index cases with clinically proven Graves' disease or Hashimoto's thyroiditis.
    These results emphasize the the importance of screening for other autoimmune diagnoses when patients with autoimmune thyroid disease show new or nonspecific symptoms.

    Celiac.com 03/03/2010 - A team of researchers set out to assess long-term outcomes of thyroid function and autoimmunity in a large population of children with celiac disease.
    The research team included Alessandra Cassio, MD, Giampaolo Ricci, MD, Federico Baronio, MD, Angela Miniaci, MD, Milva Bal, MD, Barbara Bigucci, MD, Veronica Conti, MD, and Alessandro Cicognani, MD.
    To accomplish this, they conducted a longitudinal, retrospective study at the Pediatric Department, University of Bologna, Italy (duration of follow-up, 8.9 +- 4.0 years).
    In all, the team examined one hundred thirty-five consecutive patients diagnosed between June 1990 and December 2004 and followed on a gluten-free diet.
    To be included, researchers required study subjects to maintain good dietary compliance and duration of follow-up for at least 3 years. A total of 101 patients showed no positive antithyroid titers during the follow-up, while 86 remained euthyroid; 15 showed high thyroid-stimulating hormone values at diagnosis that normalized in 11 cases after 12 to 18 months of gluten withdrawal. A total of 31 patients showed persistently positive antibody titers, with 23 of those (74%) remained consistently euthyroid during the follow-up and 8 (26%) had a subclinical hypothyroidism.
    Children with growth retardation or gastroenterological symptoms at diagnosis and different lengths of gluten exposure showed similar rates of positive antibodies.
    In children with celiac disease, antithyroid antibodies have a low clinical value for predicting the development of thyroid hypo-function during the indicated surveillance period. They encourage a more comprehensive follow-up.

    Celiac.com 02/02/2012 - A team of researchers recently conducted a prospective controlled study on a gluten-free diet and autoimmune thyroiditis in patients with celiac disease.
    The research team included S. Metso, H. Hyytiä-Ilmonen, K. Kaukinen, H. Huhtala, P. Jaatinen, J. Salmi, J. Taurio, and P. Collin. They are affiliated with the Department of Internal Medicine at Tampere University Hospital in Tampere, Finland.
    Prior to the study, there had been contradictory data regarding the ways in which early diagnosis and a gluten-free diet might slow the progression of associated autoimmune diseases in celiac disease.
    The research team investigated the course of autoimmune thyroid diseases in newly diagnosed celiac disease patients, both before and after gluten-free dietary treatment.
    For their study, the team examined twenty-seven adults with newly diagnosed celiac disease, both at the time of diagnosis and after one year on gluten-free diet.
    They also recorded and examined previously diagnosed and subclinical autoimmune thyroid diseases. The team used ultrasound to measure thyroid gland volume and echo-genicity. They also measured autoantibodies against celiac disease and thyroiditis, and conducted thyroid function tests.
    As a control group, they enrolled twenty-seven non-celiac subjects, all of whom followed a normal, gluten-containing diet.
    The data showed that, upon diagnosis, ten of 27 celiac disease patients had either manifest (n = 7) or subclinical (n = 3) thyroid diseases. Only three of 27 control subjects (10/27 vs. 3/27, p = 0.055) had thyroid disease.
    After treatment with a gluten-free diet, thyroid volume continued to decrease significantly in the patients with celiac disease compared with the control subjects, indicating the progression of thyroid gland atrophy regardless of the gluten-free diet.
    Overall, celiac patients faced a higher risk of thyroid autoimmune disorders than non-celiac control subjects. Moreover, a gluten-free diet did not seem to stop or reverse the progression of autoimmune disease after one year.

    Celiac.com 05/07/2012 - People with celiac disease face a higher risk of developing primary hyperparathyroidism (PHPT) in the early years after their celiac disease is diagnosed, according to a new report from Sweden. The report appears in the The Journal of Clinical Endocrinology & Metabolism.
    A team of researchers recently set out to examine the risk of primary hyperparathyroidism (PHPT) in people with celiac disease. The researchers included Dr. Jonas F. Ludvigsson, Olle Kämpe, Benjamin Lebwohl, Peter H. R. Green, Shonni J. Silverberg and Anders Ekbom. They are affiliated with the Department of Pediatrics (J.F.L.) at Örebro University Hospital in Örebro, Sweden, the Clinical Epidemiology Unit (J.F.L., A.E.) of the Department of Medicine at Karolinska Institutet in Stockholm, Sweden; the Department of Medical Sciences (O.K.) at Uppsala University and University Hospital in Uppsala, Sweden; and Celiac Disease Center (B.L., P.H.R.G.), and Division of Endocrinology, Department of Medicine (S.J.S.) at Columbia University College of Physicians and Surgeons in New York city, USA.
    At least one other study has suggested an association between celiac disease and primary hyperparathyroidism.
    For their study, Dr. Jonas F. Ludvigsson from Orebro University Hospital and colleagues examined the risk of PHPT among 17,121 patients with biopsy-verified celiac disease. They found that patients with celiac disease faced a 1.91-fold increased risk of PHPT compared to 85,166 matched controls.
    Ignoring the first year, due to a risk of ascertainment bias, the team found that the risk level for PHPT increased 3.29-fold through 60 months, and disappeared after that period.
    The decrease in risk level over time may be due to the beneficial effect of the gluten-free diet, the team noted. For every per 100,000 person-years at risk, the absolute risk level from one to five years of follow-up was 61 cases in patient, compared with just 22 cases in controls. The overall risk level was even greater, by 2.53 times, when the outcome was restricted to PHPT with an adenoma diagnosis in the National Cancer Registry.
    A review of the data show that the increased risk of PHPT persisted after restricting the analysis to 1987 or later, which post-date changes in ICD coding. The risk for PHPT was slightly higher for women diagnosed with celiac disease after menopause than for women diagnosed earlier in life.
    Their study does not "provide any insight into the nature of the association between celiac disease and PHPT," the authors admit. They are unsure whether the association  is causal or whether celiac disease and PHPT might be tied another unidentified condition.
    Because most patients with untreated celiac disease have vitamin D and calcium deficiencies, the team expected to find a "constellation of celiac disease and elevated parathyroid hormone levels," but that they did not expect to see a connection between celiac disease with hypercalcemia and PHPT.
    The team calls for future studies to focus on thoroughly investigating the connection, so that researchers can understand all possible aspects of the link between these two conditions.

    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.
