    It's fairly common for people with celiac disease to develop iron deficiency anemia (IDA), but researchers don't know much about the frequency with which primary care physicians test for celiac disease in patients with IDA.

    A team of researchers recently set out to describe how primary care doctors approach testing for celiac disease in asymptomatic patients with IDA.

    The research team included Marisa Spencer, Adrienne Lenhart, Jason Baker, Joseph Dickens, Arlene Weissman, Andrew J. Read, Seema Saini, and Sameer D. Saini.

    They are variously affiliated with the Department of Internal Medicine, University of Michigan, Ann Arbor, Michigan, United States of America; the Department of Internal Medicine, Henry Ford Health System, in Detroit, Michigan, United States of America; the Department of Statistics, University of Michigan, Ann Arbor, Michigan, United States of America; the Research Center at the American College of Physicians, in Philadelphia, Pennsylvania, United States of America; Department of Internal Medicine, University of Michigan, Ann Arbor, Michigan, United States of America, Ambulatory Care, Veterans Affairs Medical Center, Ann Arbor, Michigan, United States of America.

    For their study, the team began by electronically distributing a survey to primary care doctors who are members of the American College of Physicians. The survey asked whether doctors would test for celiac disease, either by serologic testing, referral for esophagogastroduodenoscopy [EGD], or referral to GI) in hypothetical patients with new IDA, including: (1) a young Caucasian man, (2) a premenopausal Caucasian woman, (3) an elderly Caucasian man, and (4) a young African American man.

    The team chose the scenarios to assess differences in testing for celiac disease based on age, gender, and race. They used multivariable logistic regression to identify independent predictors of testing.

    Testing for celiac disease varied significantly according to patient characteristics, with young Caucasian men being the most frequently tested (61% of respondents reporting they would perform serologic testing in this subgroup (p

    Interestingly 80% of doctors surveyed said they would definitely or probably start a patient with positive serologies for celiac disease on a gluten-free diet prior to confirmatory upper endoscopy, which is contrary to guideline recommendations.

    This survey indicates that primary care doctors are under-testing for celiac disease in patients with IDA, regardless of age, gender, race, or post-menopausal status. The majority of primary care doctors surveyed do not strictly adhere to established guidelines regarding a confirmatory duodenal biopsy in a patient with positive serology for celiac disease.

    Clearly, even with all of the advances in celiac disease awareness and with more refined protocols, primary care doctors have some work to do when it comes to testing IDA patients for celiac disease, and even more work to do in following proper referral guidelines before putting patients on a gluten-free diet.

    I have had two endoscopies (and colonoscopies) since reporting in 2012 that I'd had a major change in my bowel habits. Between the two endos, I was hospitalized for cellulitis-almost-sepsis—likely encouraged by what turned out was severe asymptomatic anemia: They hung three bags of iron to get me closer to normal range. I reported before both endos that I had switched to a gluten-free diet because I could no longer tolerate gluten. Neither doctor took a sample to biopsy for celiac disease.

    Celiac.com 08/18/2009 - Many of you know that DQ8 is one of the two major genes which may lead to celiac disease. You may also know that celiac disease is often associated with various other autoimmune diseases. What you may not know is that DQ8 may be the direct cause of these other autoimmune diseases, for these autoimmune diseases are found in increased incidence not just in celiac disease, but also with DQ8 itself.
    What follows is a list I have compiled showing the various diseases that are found in increased frequency among people who have the DQ8 gene (DQB1*0302). I will show the reference number next to each, and the corresponding references will appear below:

    Celiac disease (1) Scleroderma (2) Rheumatoid arthritis (1) Autoimmune thyroiditis (3) Pemphigus (4) Lupus (6) Pemphigoid (5) Focal myositis (7) Multiple sclerosis (8) Myasthenia gravis (1) Insulin dependant latent autoimmune diabetes of adults and adult Type 1 diabetes (9) Type 1 juvenile diabetes (1) Sjogren’s syndrome (10) Addisons’s disease (11) Complex regional pain syndrome with dystonia (12) Latex allergy (13)
    This list is not intended to be exhaustive. It is a starter list. Hopefully more research will be done on these, including carefully controlled research as to whether gluten plays any role in triggering these other autoimmune diseases even in the absence of gluten blood antibodies or positive duodenal biopsies. I, for one have DQ8 and numerous of these autoimmune diseases, even though my gluten blood antibodies and duodenal biopsies are negative. We who have this gene need to know for certain #1 whether a gluten free diet will help prevent the triggering of these other various autoimmune diseases, and #2 whether a gluten-free diet will help mitigate autoimmune symptoms that have already developed. I feel no better on the gluten-free diet than before I started it a year and a half ago. However, if I had not been on the diet, perhaps I would be feeling even worse now. Only controlled research will give us the answer.References:

    07/29/2013 - Rates of celiac disease in Caucasian populations of European origin are pretty well documented, but little is known about its prevalence in non-Caucasians.
    Also, data shows that celiac disease is one likely cause of iron-deficiency anemia, but little is known about how celiac disease might contribute to iron deficiency in Caucasians, and especially non-Caucasians.
    A team of researchers recently looked at for links between celiac disease and iron deficiency in both caucasians and non-caucasians.
    The study team included Joseph A. Murray, Stela McLachlan, Paul C. Adams, John H. Eckfeldt, Chad P. Garner, Chris D. Vulpe, Victor R. Gordeuk, Tricia Brantner, Catherine Leiendecker–Foster, Anthony A. Killeen, Ronald T. Acton, Lisa F. Barcellos, Debbie A. Nickerson, Kenneth B. Beckman, Gordon D. McLaren, and Christine E. McLaren.
    To find individuals with iron deficiency and to determine celiac disease rates, the team assessed samples collected from participants in the Hemochromatosis and Iron Overload Screening study. They looked at blood samples from white men 25 years or older and women 50 years or older who participated in the Hemochromatosis and Iron Overload Screening study.
    Individuals with serum ferritin levels ≤12 μg/L were group as iron deficient, while those with serum ferritin levels >100 μg/L in men and >50 μg/L in women served as a control group.
    The team analyzed all samples for human recombinant tissue transglutaminase immunoglobulin A; positive results were confirmed by an assay for endomysial antibodies.
    The team assessed patients with positive results from both celiac disease tests as having untreated celiac disease. They excluded from analysis all subjects with a positive result from only one of the two tests.
    They analyzed HLA genotypes and frequencies of celiac disease between Caucasians and non-Caucasians with iron deficiency.
    In all, the team found 14 cases of celiac disease among the 567 study subjects (2.5%), and just 1 case of celiac disease among the 1136 control subjects (0.1%; Fisher exact test, P = 1.92 × 10−6). The case of celiac disease in the control group was in a Caucasian control subject. There were no cases of celiac disease found in non-Caucasian controls.
    All 14 of the cases of celiac disease found by the team were in the Caucasian group of 363 (4%). There were no cases of celiac disease in the non-Caucasian group of 204 cases (P = .003).
    Overall, individuals with iron deficiency were 28-times more likely to have celiac disease (95% confidence interval, 3.7–212.8) than were healthy control subjects. Also, and interestingly, 13 of 14 cases with celiac disease carried the DQ2.5 variant of the HLA genotype.
    This study shows that celiac disease is linked with iron deficiency in Caucasians. In fact, among Caucasians, celiac disease is rare among individuals without iron deficiency.
    It also shows that celiac disease is rare among non-Caucasians—even among individuals with common features of celiac disease, such as iron deficiency.
    The study team recommends that doctors conduct celiac screening on men and postmenopausal women with iron deficiency.

    Celiac.com 09/05/2013 - Current medical science describes diarrhea as a classical symptom of celiac disease, while anemia is described as an atypical or silent manifestation.
    However, there was actually very little information that accurately compares the severity of celiac disease between patients who present with anemia against those who present with diarrhea.
    A team of researchers recently set out to determine whether people with anemia have more severe celiac disease than people with diarrhea.
    The research team included H.A. Daya, B. Lebwohl, S.K. Lewis, and P.H. Green. They are affiliated with the Celiac Disease Center, Department of Internal Medicine at the Columbia University College of Physicians and Surgeons in New York.
    For their study, the researchers selected a study group of 727 patients from a database of celiac disease patients evaluated at a tertiary referral center between 1990 and 2011. They used the degree of villous atrophy and clinical and serologic parameters to determine the severity of the celiac disease for each patient.
    The team compared patients according to mode of presentation and sex. They also conducted age and sex-adjusted multivariable analyses to assess the association between the mode of celiac disease presentation and cholesterol level, bone density, severity of villous atrophy, erythrocyte sedimentation rate (ESR), and level of anti-tissue transglutaminase (anti-tTG).
    They found that just over three-quarters of the patients presented with diarrhea, while just under one-quarter presented with anemia; 92% of which was iron deficient anemia.
    Multiple regression analysis showed that celiac disease with anemia was associated with lower levels of total cholesterol (P=.02) and high-density lipoprotein (P=.002), and a higher ESR (P=.001) and level of anti-tTG (P=.01).
    In women only, celiac disease with anemia was associated with a lower level of cholesterol.
    Anemic patients were more than twice as likely to have severe villous atrophy and a low bone mass density at time they were diagnosed with celiac disease than were patients who presented with diarrhea.
    So, the results show that celiac disease patients who present with anemia have more severe disease than those who present with diarrhea. There also seem to be sex-specific differences with respect to the connection between anemia and the various features of celiac disease, such as cholesterol.

    Celiac.com 06/09/2014 - Anemia is extremely common in patients with celiac disease. In some cases, anemia may be the sole manifestation of celiac disease, but there is no good data on rates of celiac disease in Indian patients with nutritional anemia. A research team recently examined rates of celiac disease among nutritional anemia patients at a care center in India. The team included A. Kavimandan, M. Sharma, A.K. Verma, P. Das, P. Mishra, S. Sinha, A. Mohan, V. Sreenivas, S. Datta Gupta, and G.K. Makharia.
    For their study, the team conducted positive celiac disease screens on adolescent and adult patients presenting with nutritional anemia. They also prospectively screened for celiac disease using IgA anti-tissue transglutaminase antibody (anti-tTG Ab). Subjects with positive antibody screens received upper gastrointestinal endoscopy and duodenal biopsy.
    In all, the team screened ninety-six patients. Of these patients, 80 had iron deficiency anemia, 11 had megaloblastic anemia, and 5 had dimorphic anemia. Seventy-three patients were receiving hematinics and 36.4 % had received blood transfusions. Nineteen patients had histories of chronic diarrhea persisting for an average of about ten years. Of those, the team found 13 patients with positive IgA anti-tTG Ab screens, 12 of whom agreed to duodenal biopsy.
    Ten patients showed villous atrophy (Marsh grade 3a in three, 3b in one, and 3c in six), while two patients showed no villous atrophy. In all, ten patients with nutritional anemia, defined as iron deficiency 9, vitamin B12 deficiency 1, were also diagnosed with celiac disease.
    Multivariate logistic regression showed age, duration of symptoms, and presence of diarrhea to be the main predictors of celiac disease. The team put all patients with celiac disease on gluten-free diet, supplemented with iron and vitamin B. All patients showed significant improvement in hemoglobin concentration.
    The team recommends celiac disease screening, and appropriate follow-up in all cases of unexplained nutritional anemia.

    Celiac.com 06/15/2018 - There seems to be widespread agreement in the published medical research reports that stuttering is driven by abnormalities in the brain. Sometimes these are the result of brain injuries resulting from a stroke. Other types of brain injuries can also result in stuttering. Patients with Parkinson’s disease who were treated with stimulation of the subthalamic nucleus, an area of the brain that regulates some motor functions, experienced a return or worsening of stuttering that improved when the stimulation was turned off (1). Similarly, stroke has also been reported in association with acquired stuttering (2). While there are some reports of psychological mechanisms underlying stuttering, a majority of reports seem to favor altered brain morphology and/or function as the root of stuttering (3). Reports of structural differences between the brain hemispheres that are absent in those who do not stutter are also common (4). About 5% of children stutter, beginning sometime around age 3, during the phase of speech acquisition. However, about 75% of these cases resolve without intervention, before reaching their teens (5). Some cases of aphasia, a loss of speech production or understanding, have been reported in association with damage or changes to one or more of the language centers of the brain (6). Stuttering may sometimes arise from changes or damage to these same language centers (7). Thus, many stutterers have abnormalities in the same regions of the brain similar to those seen in aphasia.
    So how, you may ask, is all this related to gluten? As a starting point, one report from the medical literature identifies a patient who developed aphasia after admission for severe diarrhea. By the time celiac disease was diagnosed, he had completely lost his faculty of speech. However, his speech and normal bowel function gradually returned after beginning a gluten free diet (8). This finding was so controversial at the time of publication (1988) that the authors chose to remain anonymous. Nonetheless, it is a valuable clue that suggests gluten as a factor in compromised speech production. At about the same time (late 1980’s) reports of connections between untreated celiac disease and seizures/epilepsy were emerging in the medical literature (9).
    With the advent of the Internet a whole new field of anecdotal information was emerging, connecting a variety of neurological symptoms to celiac disease. While many medical practitioners and researchers were casting aspersions on these assertions, a select few chose to explore such claims using scientific research designs and methods. While connections between stuttering and gluten consumption seem to have been overlooked by the medical research community, there is a rich literature on the Internet that cries out for more structured investigation of this connection. Conversely, perhaps a publication bias of the peer review process excludes work that explores this connection.
    Whatever the reason that stuttering has not been reported in the medical literature in association with gluten ingestion, a number of personal disclosures and comments suggesting a connection between gluten and stuttering can be found on the Internet. Abid Hussain, in an article about food allergy and stuttering said: “The most common food allergy prevalent in stutterers is that of gluten which has been found to aggravate the stutter” (10). Similarly, Craig Forsythe posted an article that includes five cases of self-reporting individuals who believe that their stuttering is or was connected to gluten, one of whom also experiences stuttering from foods containing yeast (11). The same site contains one report of a stutterer who has had no relief despite following a gluten free diet for 20 years (11). Another stutterer, Jay88, reports the complete disappearance of her/his stammer on a gluten free diet (12). Doubtless there are many more such anecdotes to be found on the Internet* but we have to question them, exercising more skepticism than we might when reading similar claims in a peer reviewed scientific or medical journal.
    There are many reports in such journals connecting brain and neurological ailments with gluten, so it is not much of a stretch, on that basis alone, to suspect that stuttering may be a symptom of the gluten syndrome. Rodney Ford has even characterized celiac disease as an ailment that may begin through gluten-induced neurological damage (13) and Marios Hadjivassiliou and his group of neurologists and neurological investigators have devoted considerable time and effort to research that reveals gluten as an important factor in a majority of neurological diseases of unknown origin (14) which, as I have pointed out previously, includes most neurological ailments.
    My own experience with stuttering is limited. I stuttered as a child when I became nervous, upset, or self-conscious. Although I have been gluten free for many years, I haven’t noticed any impact on my inclination to stutter when upset. I don’t know if they are related, but I have also had challenges with speaking when distressed and I have noticed a substantial improvement in this area since removing gluten from my diet. Nonetheless, I have long wondered if there is a connection between gluten consumption and stuttering. Having done the research for this article, I would now encourage stutterers to try a gluten free diet for six months to see if it will reduce or eliminate their stutter. Meanwhile, I hope that some investigator out there will research this matter, publish her findings, and start the ball rolling toward getting some definitive answers to this question.

    Celiac.com 06/14/2018 - Refractory celiac disease type II (RCDII) is a rare complication of celiac disease that has high death rates. To diagnose RCDII, doctors identify a clonal population of phenotypically aberrant intraepithelial lymphocytes (IELs). 
    However, researchers really don’t have much data regarding the frequency and significance of clonal T cell receptor (TCR) gene rearrangements (TCR-GRs) in small bowel (SB) biopsies of patients without RCDII. Such data could provide useful comparison information for patients with RCDII, among other things.
    To that end, a research team recently set out to try to get some information about the frequency and importance of clonal T cell receptor (TCR) gene rearrangements (TCR-GRs) in small bowel (SB) biopsies of patients without RCDII. The research team included Shafinaz Hussein, Tatyana Gindin, Stephen M Lagana, Carolina Arguelles-Grande, Suneeta Krishnareddy, Bachir Alobeid, Suzanne K Lewis, Mahesh M Mansukhani, Peter H R Green, and Govind Bhagat.
    They are variously affiliated with the Department of Pathology and Cell Biology, and the Department of Medicine at the Celiac Disease Center, New York Presbyterian Hospital/Columbia University Medical Center, New York, USA. Their team analyzed results of TCR-GR analyses performed on SB biopsies at our institution over a 3-year period, which were obtained from eight active celiac disease, 172 celiac disease on gluten-free diet, 33 RCDI, and three RCDII patients and 14 patients without celiac disease. 
    Clonal TCR-GRs are not infrequent in cases lacking features of RCDII, while PCPs are frequent in all disease phases. TCR-GR results should be assessed in conjunction with immunophenotypic, histological and clinical findings for appropriate diagnosis and classification of RCD.
    The team divided the TCR-GR patterns into clonal, polyclonal and prominent clonal peaks (PCPs), and correlated these patterns with clinical and pathological features. In all, they detected clonal TCR-GR products in biopsies from 67% of patients with RCDII, 17% of patients with RCDI and 6% of patients with gluten-free diet. They found PCPs in all disease phases, but saw no significant difference in the TCR-GR patterns between the non-RCDII disease categories (p=0.39). 
    They also noted a higher frequency of surface CD3(−) IELs in cases with clonal TCR-GR, but the PCP pattern showed no associations with any clinical or pathological feature. 
    Repeat biopsy showed that the clonal or PCP pattern persisted for up to 2 years with no evidence of RCDII. The study indicates that better understanding of clonal T cell receptor gene rearrangements may help researchers improve refractory celiac diagnosis.

    Celiac.com 06/13/2018 - There have been numerous reports that olmesartan, aka Benicar, seems to trigger sprue‐like enteropathy in many patients, but so far, studies have produced mixed results, and there really hasn’t been a rigorous study of the issue. A team of researchers recently set out to assess whether olmesartan is associated with a higher rate of enteropathy compared with other angiotensin II receptor blockers (ARBs).
    The research team included Y.‐H. Dong; Y. Jin; TN Tsacogianis; M He; PH Hsieh; and JJ Gagne. They are variously affiliated with the Division of Pharmacoepidemiology and Pharmacoeconomics, Department of Medicine, Brigham and Women's Hospital and Harvard Medical School in Boston, MA, USA; the Faculty of Pharmacy, School of Pharmaceutical Science at National Yang‐Ming University in Taipei, Taiwan; and the Department of Hepato‐Gastroenterology, Chi Mei Medical Center in Tainan, Taiwan.
    To get solid data on the issue, the team conducted a cohort study among ARB initiators in 5 US claims databases covering numerous health insurers. They used Cox regression models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for enteropathy‐related outcomes, including celiac disease, malabsorption, concomitant diagnoses of diarrhea and weight loss, and non‐infectious enteropathy. In all, they found nearly two million eligible patients. 
    They then assessed those patients and compared the results for olmesartan initiators to initiators of other ARBs after propensity score (PS) matching. They found unadjusted incidence rates of 0.82, 1.41, 1.66 and 29.20 per 1,000 person‐years for celiac disease, malabsorption, concomitant diagnoses of diarrhea and weight loss, and non‐infectious enteropathy respectively. 
    After PS matching comparing olmesartan to other ARBs, hazard ratios were 1.21 (95% CI, 1.05‐1.40), 1.00 (95% CI, 0.88‐1.13), 1.22 (95% CI, 1.10‐1.36) and 1.04 (95% CI, 1.01‐1.07) for each outcome. Patients aged 65 years and older showed greater hazard ratios for celiac disease, as did patients receiving treatment for more than 1 year, and patients receiving higher cumulative olmesartan doses.
    This is the first comprehensive multi‐database study to document a higher rate of enteropathy in olmesartan initiators as compared to initiators of other ARBs, though absolute rates were low for both groups.

    Celiac.com 06/12/2018 - A life-long gluten-free diet is the only proven treatment for celiac disease. However, current methods for assessing gluten-free diet compliance are lack the sensitivity to detect occasional dietary transgressions that may cause gut mucosal damage. So, basically, there’s currently no good way to tell if celiac patients are suffering gut damage from low-level gluten contamination.
    A team of researchers recently set out to develop a method to determine gluten intake and monitor gluten-free dietary compliance in patients with celiac disease, and to determine its correlation with mucosal damage. The research team included ML Moreno, Á Cebolla, A Muñoz-Suano, C Carrillo-Carrion, I Comino, Á Pizarro, F León, A Rodríguez-Herrera, and C Sousa. They are variously affiliated with Facultad de Farmacia, Departamento de Microbiología y Parasitología, Universidad de Sevilla, Sevilla, Spain; Biomedal S.L., Sevilla, Spain; Unidad Clínica de Aparato Digestivo, Hospital Universitario Virgen del Rocío, Sevilla, Spain; Celimmune, Bethesda, Maryland, USA; and the Unidad de Gastroenterología y Nutrición, Instituto Hispalense de Pediatría, Sevilla, Spain.
    For their study, the team collected urine samples from 76 healthy subjects and 58 patients with celiac disease subjected to different gluten dietary conditions. To quantify gluten immunogenic peptides in solid-phase extracted urines, the team used a lateral flow test (LFT) with the highly sensitive and specific G12 monoclonal antibody for the most dominant GIPs and an LFT reader. 
    They detected GIPs in concentrated urines from healthy individuals previously subjected to gluten-free diet as early as 4-6 h after single gluten intake, and for 1-2 days afterward. The urine test showed gluten ingestion in about 50% of patients. Biopsy analysis showed that nearly 9 out of 10 celiac patients with no villous atrophy had no detectable GIP in urine, while all patients with quantifiable GIP in urine showed signs of gut damage.
    The ability to use GIP in urine to reveal gluten consumption will likely help lead to new and non-invasive methods for monitoring gluten-free diet compliance. The test is sensitive, specific and simple enough for clinical monitoring of celiac patients, as well as for basic and clinical research applications including drug development.
