Abstract
BACKGROUND & AIMS The clinical effects of gluten-sensitive enteropathy with villous atrophy limited to the duodenal bulb (D1) have not been delineated in adults with celiac disease. We investigated the sensitivity of D1 biopsy analysis in the detection of celiac disease, the number and sites of biopsies required to detect ultra-short celiac disease (USCD, villous atrophy limited to D1), and the clinical phenotype of USCD. METHODS We performed a prospective study of 1378 patients (mean age, 50.3 y; 62% female) who underwent endoscopy at a tertiary medical center in the United Kingdom from 2008 through 2014; routine duodenal biopsy specimens were collected from D1 and the second part of the duodenum (D2). Quadrantic D1 biopsy specimens were collected from 171 consecutive patients with a high suspicion of celiac disease (mean age, 46.5 y; 64% female). Clinical data from patients diagnosed with USCD, based on biopsy analysis, were compared with those from patients with conventional celiac disease (CCD) (villous atrophy beyond D1) and individuals without celiac disease (controls). The number of intraepithelial lymphocytes (IELs) and immune phenotypes were compared between D1 vs D2 in patients with celiac disease. RESULTS Of the 1378 patients assessed, 268 (19.4%) were diagnosed with celiac disease; 9.7% of these patients had villous atrophy confined to D1 (USCD; P < .0001). Collection of a single additional biopsy specimen from any D1 site increased the sensitivity of celiac disease detection by 9.3%-10.8% (P < .0001). Patients with USCD were younger (P = .03), had lower titers of tissue transglutaminase antibody (P = .001), and less frequently presented with diarrhea (P = .001) than patients with CCD. Higher proportions of patients with CCD had ferritin deficiency (P = .007) or folate deficiency (P = .003) than patients with USCD or controls. Patients with celiac disease had a median of 50 IELs/100 enterocytes in D1 and a median of 48 IELs/100 enterocytes (P = .7) in D2. The phenotype of IELs from patients with D1 celiac disease was indistinguishable from those of patients with D2 celiac disease. CONCLUSIONS Collection of a single additional biopsy specimen from any site in the D1 intestine increases the sensitivity of detection for celiac disease. Patients with USCD may have early stage or limited celiac disease, with a mild clinical phenotype and infrequent nutritional deficiencies.

A large variety of clinical features and concomitant disorders in celiac disease - A cohort study in the Netherlands. Dig Liver Dis 2016; 48:499-505. [PMID: 26854256 DOI: 10.1016/j.dld.2016.01.006] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2015] [Revised: 12/09/2015] [Accepted: 01/07/2016] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Celiac disease (CeD) is a gluten triggered, immune-mediated disease of the small intestine. Few clinical cohort descriptions are available, despite the diverse clinical picture. This study provides an overview of a large Dutch CeD cohort focusing on presenting symptoms, co-occurrence of immune mediated diseases (IMD) and malignancies. METHODS We performed a retrospective study in a Dutch university and a non-university medical hospital and included only biopsy proven (≥Marsh type 2 classification) CeD patients. RESULTS 412 patients were included, selected from 9468 small-bowel biopsy pathology reports and financial codes. Classical symptoms were present in approximately one third of the cohort (diarrhea (37.4%), fatigue (35.0%), weight loss (31.6%), abdominal pain (33.3%)). Atypical symptoms as constipation (10.4%) and reflux (12.4%) were reported as well. 11.7% was diagnosed without reported symptoms. In 25.2% concomitant IMD occurred (most prevalent: type 1 diabetes mellitus (4.9%), microscopic colitis (4.9%), immune mediated-thyroid disease (4.1%)). CeD patients with a concomitant IMD were diagnosed at a significantly higher age compared to those without (P=0.002). Malignancies occurred in 53 cases (12.9%), including eight Enteropathy Associated T-cell Lymphomas. CONCLUSION This is the first study describing a CeD cohort in such detail in the Netherlands and highlights the clinical heterogeneity and importance of screening for concomitant diseases in CeD.

Abstract
BACKGROUND Indications to double-balloon enteroscopy (DBE) are not standardized in celiac disease (CD). GOALS To evaluate the clinical usefulness of DBE in complicated CD. STUDY DBE findings in celiac patients with suspected small bowel (SB) complications were retrospectively evaluated in 2 tertiary referral centers (Milan and Sheffield). Demographic data of the studied cohort were compared with a database of 1000 noncomplicated CD patients. RESULTS Twenty-four CD cases (12 males, P=0.01 vs. controls) were reviewed. Mean age at CD diagnosis (y±SD) was 37±20 versus 27±18 and at SB evaluation 47±15 versus 38±13 (P<0.01 compared with controls). Indications for DBE were refractory CD (#9), gastrointestinal symptoms (#6), severe iron-deficiency anemia (#6), and long standing poor dietary adherence (#3). Two jejunal adenocarcinomas and an ileal neuroendocrine tumor were detected in presence of iron-deficiency anemia. Three type I and 3 type II refractory CD patients showed jejunal ulcerations; 2 of type II presented small white raised patches. Patchy atrophy was observed in nonadherent patients and in 2 on a gluten-free diet for a short time. Therapy was planned in 33% of patients after DBE. No adverse events were detected at follow-up [21 mo (range, 0 to 60 mo)]. CONCLUSIONS This is the largest international study on the outcomes of DBE in CD demonstrating its usefulness to exclude/confirm malignant or premalignant conditions, associated with even minor lesions. Studies are needed to understand the clinical relevance of the SB endoscopic features and to optimize DBE indications.

Abstract
BACKGROUND Several studies have shown an excess mortality in individuals with celiac disease (CD). However, it is unknown if also first-degree relatives (FDRs) to celiac patients are at increased risk of death. AIM We aimed to assess mortality in FDRs to celiac patients. METHODS Individuals with CD were identified through biopsy reports (equal to Marsh grade III). Each celiac individual was matched on sex, age, county and calendar year with up to five control individuals. Through Swedish healthcare registries we identified all FDRs (father, mother, sibling, offspring) of CD individuals and controls. Through Cox regression we calculated hazard ratios (HRs) for mortality (all-cause death, circulatory, cancer and other). RESULTS We identified 109,309 FDRs of celiac individuals and 549,098 FDRs of controls. Overall mortality was increased in FDRs to celiac individuals (HR=1.02, 95%CI=1.00-1.04, p=0.03). This corresponded to an excess risk of 5.9 deaths per 100,000 person-years of follow-up. When limiting follow-up to time since celiac diagnosis in the index individual, we found no increased risk of death (HR=1.01; 95%CI=0.98-1.03). CONCLUSION FDRs to individuals with CD are at increased risk of death. This excess risk is however minimal and unlikely to be of any clinical importance to the individual.

Abstract
OBJECTIVE A state-of-the-art assessment of duodenal biopsies by the pathologist in the diagnosis of celiac disease (CelD) is of highest importance. However, inaccurate characterization of specific features can lead to misdiagnosis. Our hypothesis is that a detailed histological report guarantees a good quality and helps in the primary diagnostic process by preventing false-positive diagnosis of CelD. MATERIAL AND METHODS A total of 52 patients primarily diagnosed with CelD and suspicion of misdiagnosis were selected for this retrospective study. External histological reports of duodenal biopsies were obtained and later reassessed by an experienced in-house pathologist. For an objective evaluation a histology quality score (HQS) was created. Both pathological reports were compared and causes for a possible misdiagnosis were analyzed. Diagnostic systems by Catassi and Korponay-Szabo were compared with each other. RESULTS The original diagnosis had been confirmed in 27% by our pathologist. The HQS was significantly lower (worse) in cases where the original diagnosis were dismissed than in confirmed CelD (p = 0.018). The new diagnostic approach by Catassi and Korponay-Szabo showed a sensitivity of 89% and 83%, respectively, a specificity of 97%, a positive predictive value of 94% and a negative predictive value of 94% and 92%, respectively. CONCLUSIONS A low quality of the histological evaluation can lead to a high probability of misdiagnosing CelD. By applying the HQS the physician can estimate whether the report is fraught with uncertainty. Ideally the score minimizes false-positive results and prevents a delay of the correct diagnosis.

Abstract
Celiac disease is a relatively common immunological systemic disease triggered by the protein gluten in genetically predisposed individuals. Classical symptoms like chronic diarrhea, steatorrhea, weight loss and growth retardation are nowadays relatively uncommon. Diagnostic workup includes serological tests for IgA antibodies against tissue transglutaminase 2 (anti-TG2-IgA) and total IgA and histology of duodenal biopsies. Histomorphological classification should be done according to the modified Marsh-Oberhuber classification. Diagnosis of celiac disease should be based on serological, clinical, and histological findings. The only treatment is a life-long gluten-free diet. Unchanged or recurrent symptoms under gluten-free diet may indicate refractory celiac disease. Enteropathy-associated T-cell lymphoma and adenocarcinomas of the small intestine are known complications of celiac disease.

Abstract
OBJECTIVES Although celiac disease (CeD) affects 1% of people in the northern part of India, it is believed to be uncommon in the southern and northeastern parts because of significant differences in dietary pattern and ethnicity. We estimated the prevalence of CeD in these three populations. In a subset, we also investigated differences in the prevalence of HLA-DQ 2/8 allelotype and dietary grain consumption. METHODS A total of 23,331 healthy adults were sampled from three regions of India-northern (n=6207), northeastern (n=8149), and southern (n=8973)-and screened for CeD using IgA anti-tissue transglutaminase antibody. Positive tests were reconfirmed using a second ELISA. CeD was diagnosed if the second test was positive and these participants were further investigated. A subsample of participants was tested for HLA-DQ2/-DQ8 and underwent detailed dietary evaluation. RESULTS Age-adjusted prevalence of celiac autoantibodies was 1.23% in northern, 0.87% in northeastern, and 0.10% in southern India (P<0.0001). Prevalence of CeD and latent CeD, respectively, was 8.53/1,000 and 3.70/1,000 in northern, 4.66/1,000 and 3.92/1,000 in northeastern, and 0.11/1,000 and 1.22/1,000 in the southern part. The population prevalence of genes determining HLA-DQ2 and/or -DQ8 expression was 38.1% in northern, 31.4% in northeastern, and 36.4% in southern India. Mean daily wheat intake was highest in northern (455 g) compared with northeastern (37 g) or southern part (25 g), whereas daily rice intake showed an inverse pattern. CONCLUSIONS CeD and latent CeD were most prevalent in northern India and were the least in southern India. The prevalence correlated with wheat intake and did not reflect differences in the genetic background.

Abstract
OBJECTIVES To chart trends in the presentation of celiac disease in a large cohort of Finnish children diagnosed over a period of 48 years. STUDY DESIGN Clinical and serologic data, severity of small-bowel mucosal damage, and presence of associated conditions were gathered from 596 children diagnosed with celiac disease in 1966-2013. The children were divided into 4 groups based on the year of diagnosis (before 1980, 1980-1999, 2000-2009, and 2010-2013), and the variables were compared between the periods. The incidence of celiac disease autoimmunity in 2001-2013 was calculated based on the number of new antibody-positive cases in each year. RESULTS Age at diagnosis rose from median 4.3 years before 1980 to between 7.6 and 9.0 years in the later periods. The severity of clinical presentation, in general, became milder and poor growth less common during the entire study period of 50 years. Percentages of children with classical gastrointestinal presentation decreased, and those with atypical or subclinical presentation increased after the 1990s, these changes leveling off in 2000-2013. Similarly, the severity of small-bowel mucosal damage was milder after the 1990s. The incidence of celiac disease autoimmunity increased in the early 2000s but then fluctuated without a clear trend. There were no significant secular changes in sex distribution, presence of anemia, levels of celiac antibodies, or celiac disease-associated conditions. CONCLUSIONS The clinical and histologic presentation of celiac disease in children became milder, especially in the 1980s and 1990s. However, most of these changes have reached a plateau in recent years.

Abstract
Notwithstanding a growth in popularity and consumption of gluten-free (GF) food products, there is a lack of substantiated analysis of the nutritional quality compared with their gluten-containing counterparts. To put GF foods into proper perspective both for those who need it (patients with celiac disease) and for those who do not, we provide contemporary data about cost and nutritional quality of GF food products. The objective of this study is to develop a food composition database for seven discretionary food categories of packaged GF products. Nutrient composition, nutritional information and cost of foods from 63 GF and 126 gluten-containing counterparts were systematically obtained from 12 different Austrian supermarkets. The nutrition composition (macro and micronutrients) was analyzed by using two nutrient composition databases in a stepwise approximation process. A total of 63 packaged GF foods were included in the analysis representing a broad spectrum of different GF categories (flour/bake mix, bread and bakery products, pasta and cereal-based food, cereals, cookies and cakes, snacks and convenience food). Our results show that the protein content of GF products is >2 fold lower across 57% of all food categories. In 65% of all GF foods, low sodium content was observed (defined as <120 mg/100 g). Across all GF products, 19% can be classified as source high in fiber (defined as >6g/100 g). On average, GF foods were substantially higher in cost, ranging from +205% (cereals) to +267% (bread and bakery products) compared to similar gluten-containing products. In conclusion, our results indicate that for GF foods no predominant health benefits are indicated; in fact, some critical nutrients must be considered when being on a GF diet. For individuals with celiac disease, the GF database provides a helpful tool to identify the food composition of their medical diet. For healthy consumers, replacing gluten-containing products with GF foods is aligned with substantial cost differences but GF foods do not provide additional health benefits from a nutritional perspective.

Abstract
An old saying states that ''children are not little adults" and this certainly holds true for celiac disease, as there are many peculiar aspects regarding its epidemiology, diagnosis, clinical presentations, associated diseases, and response to treatment in pediatric compared to adult populations, to such an extent that it merits a description of its own. In fact, contrary to the past when it was thought that celiac disease was a disorder predominantly affecting childhood and characterized by a malabsorption syndrome, nowadays it is well recognized that it affects also adult and elderly people with an impressive variability of clinical presentation. In general, the clinical guidelines for diagnosis recommend starting with specific serologic testing in all suspected subjects, including those suffering from extraintestinal related conditions, and performing upper endoscopy with appropriate biopsy sampling of duodenal mucosa in case of positivity. The latter may be omitted in young patients showing high titers of anti-transglutaminase antibodies. The subsequent management of a celiac patient differs substantially depending on the age at diagnosis and should be based on the important consideration that this is a lifelong condition.

Application of Deamidated Gliadin Antibodies in the Follow-Up of Treated Celiac Disease. PLoS One 2015; 10:e0136745. [PMID: 26322980 PMCID: PMC4554732 DOI: 10.1371/journal.pone.0136745] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2015] [Accepted: 08/06/2015] [Indexed: 12/31/2022] Open
Abstract
Introduction The role of serological tests such as IgA anti-transglutaminase autoantibodies has become increasingly important in celiac disease (CD) diagnosis. However, the efficiency of these tests for patient follow-up is controversial. We investigated the correlation of 12 different serological tests, including recent deamidated gliadin and actin IgA tests, with villous atrophy (VA) in a retrospective cohort of treated celiac patients. Materials and Methods Serum samples were collected from 100 treated CD patients who had intestinal biopsy in the course of their follow-up. Antibodies against transglutaminase, deamidated gliadin peptides, and native gliadin were measured, along with IgA anti-actin. The biopsy slides were all blind-reviewed and scored according to Marsh classification. Results For all deamidated gliadin and transglutaminase tests, we found that a positive result was significantly associated with persistence of intestinal VA, with a diagnostic efficacy up to 80%. Furthermore, antibodies titers directly correlated with the degree of VA, indicating a strong link between disease activity and presence of antibodies in the serum. Interestingly, the tests with the highest association with persistent VA were those for deamidated gliadin IgG. Using a test positivity pattern analysis, we were also able to identify several groups of patients with distinct antibody profiles that showed significant differences in intestinal damage and diet compliance. Conclusions Altogether, these results show that deamidated gliadin antibodies are strongly correlated with VA and should be considered valuable tools in CD follow-up and that multiplex serologic analysis for treated CD represents a promising tool for personalized patient management.

Goblet Cell Derived RELM-β Recruits CD4+ T Cells during Infectious Colitis to Promote Protective Intestinal Epithelial Cell Proliferation. PLoS Pathog 2015; 11:e1005108. [PMID: 26285214 PMCID: PMC4540480 DOI: 10.1371/journal.ppat.1005108] [Citation(s) in RCA: 71] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2015] [Accepted: 07/23/2015] [Indexed: 12/15/2022] Open
Abstract
Enterohemorrhagic Escherichia coli and related food and waterborne pathogens pose significant threats to human health. These attaching/effacing microbes infect the apical surface of intestinal epithelial cells (IEC), causing severe diarrheal disease. Colonizing the intestinal luminal surface helps segregate these microbes from most host inflammatory responses. Based on studies using Citrobacter rodentium, a related mouse pathogen, we speculate that hosts rely on immune-mediated changes in IEC, including goblet cells to defend against these pathogens. These changes include a CD4+ T cell-dependent increase in IEC proliferation to replace infected IEC, as well as altered production of the goblet cell-derived mucin Muc2. Another goblet cell mediator, REsistin-Like Molecule (RELM)-β is strongly induced within goblet cells during C. rodentium infection, and was detected in the stool as well as serum. Despite its dramatic induction, RELM-β’s role in host defense is unclear. Thus, wildtype and RELM-β gene deficient mice (Retnlb-/-) were orally infected with C. rodentium. While their C. rodentium burdens were only modestly elevated, infected Retnlb-/- mice suffered increased mortality and mucosal ulceration due to deep pathogen penetration of colonic crypts. Immunostaining for Ki67 and BrDU revealed Retnlb-/- mice were significantly impaired in infection-induced IEC hyper-proliferation. Interestingly, exposure to RELM-β did not directly increase IEC proliferation, rather RELM-β acted as a CD4+ T cell chemoattractant. Correspondingly, Retnlb-/- mice showed impaired CD4+ T cell recruitment to their infected colons, along with reduced production of interleukin (IL)-22, a multifunctional cytokine that directly increased IEC proliferation. Enema delivery of RELM-β to Retnlb-/- mice restored CD4+ T cell recruitment, concurrently increasing IL-22 levels and IEC proliferation, while reducing mucosal pathology. These findings demonstrate that RELM-β and goblet cells play an unexpected, yet critical role in recruiting CD4+ T cells to the colon to protect against an enteric pathogen, in part via the induction of increased IEC proliferation. Food and water-borne bacterial pathogens such as enterohemorrhagic Escherichia coli (EHEC) target the epithelial cells that line the inner surface of their host’s intestines, causing inflammation and diarrhea. While professional immune cells including T lymphocytes are well known for promoting host defense, we hypothesized that as the cells in closest contact with these bacterial pathogens, intestinal epithelial cells also play an active and essential role in protecting the host during infection. Infecting mice with Citrobacter rodentium, a mouse specific relative of EHEC, we noted a dramatic upregulation in the expression and secretion of the mediator RELM-β by a subset of epithelial cells called goblet cells. Compared to wildtype mice, mice lacking RELM-β showed less epithelial cell proliferation and suffered significantly more intestinal damage during infection. Rather than directly causing epithelial cell proliferation, we found RELM-β instead recruited T lymphocytes to the infected intestine. Upon reaching the intestine, the T lymphocytes produced the cytokine interleukin-22, which directly increased epithelial cell proliferation. Taken together, these findings indicate that epithelial/goblet cells play a critical role in orchestrating the host response to an intestinal pathogen, by recruiting T lymphocytes and by promoting epithelial proliferation to limit the intestinal damage suffered during infection.

Prevalence of abnormal liver function tests in celiac disease and the effect of a gluten-free diet in the US population. Am J Gastroenterol 2015; 110:1216-22.

Abstract
OBJECTIVES Guidelines recommend routine screening of liver function tests (LFTs) in patients diagnosed with celiac disease (CD). However, little is known about the prevalence of liver disorders in CD outside of Europe. Our aims were to estimate the prevalence of LFT abnormalities in CD and to evaluate the effect of a gluten-free diet (GFD) on LFTs. METHODS Adult patients with biopsy-proven CD were identified from a prospectively maintained database and matched with healthy controls. LFT levels for women and men were defined as abnormal based on the Third National Health and Nutrition Examination Survey (NHANES III) criteria. Data on demographics, coexisting liver diseases, and laboratory work-ups including aspartate transaminase (AST) and alanine transaminase (ALT) values at the time of diagnosis and on a GFD were recorded. Subsequently, data from this cohort were compared with data from 7,789 individuals participating in the National Health and Nutrition Examination Survey, 2009-2010. Univariate logistic regression, Wilcoxon signed-ranks, Student's t-test, χ(2), and Fischer's exact test were used for statistical analysis. RESULTS In 463 CD patients with ALT or AST levels at the time of CD diagnosis, 40.6% had elevated LFTs compared with 24.2% of treated CD patients (P<0.001) and 16.6% of matched controls (P<0.001). Similarly, 36.7% of CD patients on the NHANES database had abnormal ALT values compared with 19.3% of non-celiac patients (P=0.03). Approximately, 78.6% of CD patients with elevated LFTs at diagnosis normalized LFTs on a GFD after a mean duration of 1.5±1.5 years. CONCLUSIONS Forty percent of individuals will have elevated LFTs at CD diagnosis; however, the majority will normalize with standard CD therapy. LFTs should be checked in all patients with CD and coexisting liver disorder should be considered in patients whose LFTs have not improved within a year on a GFD.

J Nutr 2015; 145:1604-13.

Abstract
BACKGROUND The integrity of the epithelial layer in the gastrointestinal tract protects organisms from exposure to luminal antigens, which are considered the primary cause of chronic intestinal inflammation and allergic responses. The common wheat-associated fungal toxin deoxynivalenol acts as a specific disruptor of the intestinal tight junction network and hence might contribute to the pathogenesis of inflammatory bowel diseases. OBJECTIVE The aim of the current study was to assess whether defined galacto-oligosaccharides (GOSs) can prevent deoxynivalenol-induced epithelial dysfunction. METHODS Human epithelial intestinal Caco-2 cells, pretreated with different concentrations of GOSs (0.5%, 1%, and 2%) for 24 h, were stimulated with 4.2-μM deoxynivalenol (24 h), and 6/7-wk-old male B6C3F1 mice were fed a diet supplemented with 1% GOSs for 2 wk before being orally exposed to deoxynivalenol (25 mg/kg body weight, 6 h). Barrier integrity was determined by measuring transepithelial electrical resistance (TEER) and intestinal permeability to marker molecules. A calcium switch assay was conducted to study the assembly of epithelial tight junction proteins. Alterations in tight junction and cytokine expression were assessed by quantitative reverse transcriptase-polymerase chain reaction, Western blot analysis, or ELISA, and their localization was visualized by immunofluorescence microscopy. Sections of the proximal and distal small intestine were stained with hematoxylin/eosin for histomorphometric analysis. RESULTS The in vitro data showed that medium supplemented with 2% GOSs improved tight junction assembly reaching an acceleration of 85% after 6 h (P < 0.05). In turn, GOSs prevented the deoxynivalenol-induced loss of epithelial barrier function as measured by TEER (114% of control), and paracellular flux of Lucifer yellow (82.7% of prechallenge values, P < 0.05). Moreover, GOSs stabilized the expression and cellular distribution of claudin3 and suppressed by >50% the deoxynivalenol-induced synthesis and release of interleukin-8 [IL8/chemokine CXC motif ligand (CXCL8)] (P < 0.05). In mice, GOSs prevented the deoxynivalenol-induced mRNA overexpression of claudin3 (P = 0.022) and CXCL8 homolog keratinocyte hemoattractant (Kc) (Cxcl1) (P = 0.06) as well as the deoxynivalenol-induced morphologic defects. CONCLUSIONS The results demonstrate that GOSs stimulate the tight junction assembly and in turn mitigate the deleterious effects of deoxynivalenol on the intestinal barrier of Caco-2 cells and on villus architecture of B6C3F1 mice.

Abstract
OBJECTIVES The aim of the present study was to evaluate any potential correlation between anti-tissue transglutaminase antibodies of type immunoglobulin A (tTG-IgA) and the degree of gluten-induced enteropathy in children participating in a screening study for celiac disease (CD) and to assess to what extent the revised European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) guidelines cover this group of patients. METHODS The present study is a substudy of a cross-sectional CD screening study, Exploring the Iceberg of Celiacs in Sweden, a 2-phased study performed during 2005 to 2006 and 2009 to 2010. The 13,279 participating children had a blood test obtained, and those with positive tTG-IgA were recommended a small intestinal biopsy. The tTG-IgA levels at the time of biopsy were compared with those at the assessment of the biopsy. RESULTS There were 267 children included, of whom 230 were diagnosed as having CD. Of all of the children, 67 children had low tTG-IgA levels (<5 U/mL), of whom 55% had Marsh 3 lesions. All of the children with tTG-IgA levels exceeding 10 times the upper limit of normal values of 5 U/mL, that is, 50 U/mL, were diagnosed as having CD. Lowering the cutoff to 3 U/mL, all but 1 child with 30 U/mL got CD diagnosis. CONCLUSIONS By adopting the revised ESPGHAN criteria, biopsies could have been omitted in one-fourth of all of the patients. Our results indicate that the criteria may be useful even in screened children. Further studies are needed to confirm whether the 2012 ESPGHAN guidelines should be revised to also apply to the populations being screened.

Abstract
CONTEXT Clinical presentation of celiac disease is extremely variable and the diagnosis relies on serologic tests, mucosal intestinal biopsy and clinic and serologic response to a gluten-free diet. OBJECTIVES To correlate the endoscopic and histological aspects of adult patients with suspicion of celiac disease and to evaluate the interobserver histological agreement. METHODS Endoscopic aspects of 80 adult patients were evaluated and correlated with the histological features according the Marsh-Oberhuber classification system. The interobserver histological agreement was based on kappa values. RESULTS The symptoms of the patients varied largely, with prominence for chronic diarrhea, present in 48 (60%) patients. The endoscopic aspects related with the duodenal villous atrophy had been observed in 32 (40%) patients. There were confirmed 46 cases of celiac disease, with prevalence of 57.5%. The sensitivity, specificity, positive predictive value and negative predictive value of the endoscopic markers for celiac disease diagnosis were of 60.9%, 88.2%, 87.5% and 62.5%. There was moderate interobserver histological agreement (kappa = 0.46). CONCLUSIONS The endoscopic markers of villous atrophy, although not diagnostic, had assisted in the suspicion and indication of the duodenal biopsies for diagnosis proposal. Histology is sometimes contradictory and new biopsies or opinion of another professional can provide greater diagnostic agreement.

Abstract
The publication of papers on the topic of gluten related disorders has substantially increased over the last few years. This has motivated healthcare professionals to pay attention not only to celiac disease and wheat allergy but also to a condition termed nonceliac gluten sensitivity (NCGS). Until now this condition has been diagnosed clinically on the basis of exclusion criteria and clinical response to gluten withdrawal. In addition, recent research in this field has shown that other food components distinct from gluten are implicated in NCGS cases, thereby changing our general understanding of NCGS diagnosis in either individuals on gluten containing diets or those already following a gluten-free diet with no proper diagnostic work-up of celiac disease. With this in mind, the assessment of NCGS will require extensive knowledge of celiac disease manifestations and the laboratory tests commonly performed during diagnosis of celiac disease.

Abstract
Microscopic enteritis (ME) is an inflammatory condition of the small bowel that leads to gastrointestinal symptoms, nutrient and micronutrient deficiency. It is characterised by microscopic or sub-microscopic abnormalities such as microvillus changes and enterocytic alterations in the absence of definite macroscopic changes using standard modern endoscopy. This work recognises a need to characterize disorders with microscopic and submicroscopic features, currently regarded as functional or non-specific entities, to obtain further understanding of their clinical relevance. The consensus working party reviewed statements about the aetiology, diagnosis and symptoms associated with ME and proposes an algorithm for its investigation and treatment. Following the 5th International Course in Digestive Pathology in Bucharest in November 2012, an international group of 21 interested pathologists and gastroenterologists formed a working party with a view to formulating a consensus statement on ME. A five-step agreement scale (from strong agreement to strong disagreement) was used to score 21 statements, independently. There was strong agreement on all statements about ME histology (95%-100%). Statements concerning diagnosis achieved 85% to 100% agreement. A statement on the management of ME elicited agreement from the lowest rate (60%) up to 100%. The remaining two categories showed general agreement between experts on clinical presentation (75%-95%) and pathogenesis (80%-90%) of ME. There was strong agreement on the histological definition of ME. Weaker agreement on management indicates a need for further investigations, better definitions and clinical trials to produce quality guidelines for management. This ME consensus is a step toward greater recognition of a significant entity affecting symptomatic patients previously labelled as non-specific or functional enteropathy.

Mucosal histopathology in celiac disease: a rebuttal of Oberhuber's sub-division of Marsh III. GASTROENTEROLOGY AND HEPATOLOGY FROM BED TO BENCH 2015; 8:99-109.

Abstract
Individuals with particular genetic backgrounds develop immune responses to wheat proteins and become 'gluten-sensitised'. Mucosal pathology arises through activated mucosal T lymphocytes, resulting in a graded, adverse reaction between particular genes and wheat proteins. Given these varied influences, the Marsh Classification broadly itemises those stages through which a normal mucosa (Marsh 0) evolves in becoming 'flat' (Marsh I, II, III). Recently, Oberhuber and colleagues suggested that Marsh III lesions required subdividing into a, b, c categories. We critically examined these subdivisions by means of correlative light and scanning electron microscopy (SEM). Our results demonstrate that Oberhuber's classification is untenable. In our view deriving from our observations, the artificial subdivisions proposed by those authors actually reflect misinterpretations of the true architectural contours of flat mucosae. Although these workers refer to "villous projections", SEM demonstrates that no such structures are present on flat - or immediately recovering - mucosae. Our data revealed on the surfaces of flat (Marsh III) mucosae, large open "basins", surrounded by raised collars - the latter, when viewed in histological section, being easily misconstrued as "villi". It seems that with subsequent upward growth, these collars coalesce into low ridges, thence becoming broader and higher convolutions. It is noticeable that there are more open spaces on the surfaces of flat mucosae than was appreciated hitherto. We conclude that Oberhuber's revisions of Marsh III into three subcategories (a, b, c), are misinterpretations of the histological appearances of flattened mucosae. Therefore, histopathologists when classifying celiac mucosae, since they add nothing either of diagnostic, nor prognostic, value should resist these subcategories.

Abstract
BACKGROUND/AIM In celiac disease (CD), there is increased mRNA coding for tissue transglutaminase (tTG) and interferon gamma (IFNα). In seronegative celiac patients, the mucosal immune complexes anti-tTG IgA/tTG are found. We assayed tTG- and IFNα-mRNA in the mucosa of patients with a clinical suspicion of seronegative CD and correlated the values with intraepithelial CD3 lymphocytes (IELs). MATERIALS AND METHODS Distal duodenum specimens from 67 patients were retrieved and re-evaluated for immunohistochemically proven CD3 IELs. Five 10 μm sections were used for the extraction and assay of tTG and IFNα coding mRNA levels using reverse transcriptase real-time polymerase chain reaction (RT-PCR). Samples from 15 seropositive CD patients and 15 healthy subjects were used as positive and negative controls. Results were expressed as fold-change. RESULTS Our series was divided into three groups based on IEL count: >25 (14 patients: group A), 15-25 (26 patients: group B), and 0-15 (27 patients: Group C). tTG-mRNA levels were (mean ± SD): CD = 9.8 ± 2.6; group A = 10.04 ± 4.7; group B = 4.99 ± 2.3; group C = 2.26 ± 0.8, controls = 1.04 ± 0.2 (CD = group A > group B > group C = controls). IFNα-mRNA levels were: CD = 13.4 ± 3.6; group A = 7.28 ± 3.6; group B = 4.45 ± 2.9; group C = 2.06 ± 1.21, controls = 1.04 ± 0.4. CONCLUSIONS Our results suggest that tTG- and IFNγmRNA levels are increased in both seropositive and potential seronegative patients with CD, showing a strong correlation with the CD3 IEL count at stage Marsh 1. An increase in both molecules is found even when IELs are in the range 15-25 (Marsh 0), suggesting the possibility of a "gray zone" inhabited by patients which should be closely followed up in gluten-related disorders.

Abstract
Background:Although it is acknowledged that patients with celiac disease can develop neurological complications such as ataxia, the association of antigliadin antibodies in the etiology of sporadic ataxia and the usefulness of this testing in diagnosis of ataxia is controversial.Methods:We investigated this association by testing for the presence of IgG and IgA antigliadin antibodies in 56 ataxic patients and 59 controls. The ataxia patients were subsequently classified into three groups: sporadic, hereditary and MSA.Results:Of the total ataxic patients, 6/56 (11%) were positive for either IgG or IGA antigliadin antibodies compared to the controls of which 5/59 (8%) were positive (p = 0.68). In a subgroup analysis, 4/29 (14%) of the samples in the sporadic ataxic subgroup were positive for antigliadin antibodies (IgG or IgA) compared to control (p = 0.44). Similar negative results were found in the remaining subgroup analyses.Conclusions:These results do not support an association between antigliadin antibodies and sporadic ataxias.

Abstract
INTRODUCTION The only current treatment for celiac disease is a strict gluten-free diet. The ubiquitous presence of gluten in groceries, however, makes the diet burdensome and difficult to maintain, and alternative treatment options are thus needed. Here, the important role of transglutaminase 2 (TG2) in the pathogenesis of celiac disease makes it an attractive target for drug development. AREAS COVERED The present paper gives an overview of TG2 and addresses its significance in the pathogenesis of celiac disease. Moreover, the article summarizes preclinical studies performed with TG2 inhibitors and scrutinizes issues related to this therapeutic approach. EXPERT OPINION Activation of TG2 in the intestinal mucosa is central in celiac disease pathogenesis and researchers have therefore suggested TG2 inhibitors as a potential therapeutic approach. However, a prerequisite for such a drug is that it should be specific for TG2 and not affect the activity of other members of the transglutaminase family. Such compounds have already been introduced and tested in vitro, but a major obstacle to further development is the lack of a well-defined animal model for celiac disease. Nonetheless, with encouraging results in preclinical studies clinical trials with TG2 inhibitors are eagerly awaited.

Abstract
Background Smoking status has been linked to several chronic inflammatory conditions but earlier research on smoking and celiac disease (CD) is contradictive. There are little data on moist snuff use and CD. The purpose of this study was to investigate the association between smoking, moist snuff use and later CD. Methods We identified individuals with biopsy-verified CD (villous atrophy, histopathology stage Marsh III) through biopsy-reports from Sweden’s 28 pathology departments. Data on smoking and moist snuff were collected from the Swedish construction worker database “Bygghälsan” that includes preventive health care check-up data. Through poisson regression we calculated relative risks (RRs) for later CD according to smoking status (n = 305,722), and moist snuff status (n = 199,200) adjusting for age, sex and decade. Results During follow-up 488 individuals with smoking data, and 310 with moist snuff data had a diagnosis of CD. The risk of CD was independent of smoking status with all RRs being statistically insignificant and ranging between 0.9 and 1.0. Compared to non-smokers, neither current smokers (RR = 0.93; 95% CI = 0.76-1.14) nor ex-smokers (RR = 0.98; 95% CI = 0.75-1.28) were at increased or decreased risk of CD. Risk estimates were similar in moderate smokers (RR = 0.92; 0.72-1.16) and heavy smokers (RR = 0.95; 0.74-1.24), and did not change when we examined the risk more than ten years after health examination (RR-moderate: 0.90; and RR-heavy: 0.95; both p > 0.05). Moist snuff use was not associated with later CD (RR = 1.00; 0.78-1.28), or with CD after more than ten years of follow-up (RR = 1.05; 0.80-1.38). Conclusions We found no association between smoking, moist snuff use and future CD.

Abstract
BACKGROUND Currently, the only treatment for celiac disease (CD) is a lifelong gluten-free diet (GFD). Research has been carried out in various countries into the nutritional adequacy of the GFD in terms of macro- and micronutrients, mostly presenting conflicting results. However, no data for Germany are available to date. AIM To elucidate the nutritional composition of a GFD and to compare it with non-GFD in a representative German non-CD population. METHODS AND PATIENTS A total of 1,000 patients who were members of the German Celiac Society (DZG) were invited to fill out a prospective 7-day food diary and a questionnaire. Data from 88 patients aged 14-80 years were analyzed and compared to the DACH reference values and to data from the German National Diet and Nutrition Survey (NVS II). RESULTS No significant difference was observed for the intake of energy and macronutrients in male celiac patients compared to the NVS II. Only the fiber intake of male patients was significantly lower than that of the general population. Female patients, however, showed a significantly higher fat intake, but lower carbohydrate consumption. The average daily micronutrient intake of male and female patients, specifically of vitamin B1, B2, B6, folic acid, magnesium and iron, was significantly lower in celiac patients compared to the NVS II. CONCLUSION This study reveals inadequate nutrient intake by male and female celiac patients in Germany. Based on our findings, regular (laboratory) monitoring of celiac patients should be recommended.

Estimated levels of gluten incidentally present in a Canadian gluten-free diet. Nutrients 2014; 6:881-96.

Abstract
Avoiding exposure to gluten is currently the only effective treatment for celiac disease. However, the evidence suggests that for most affected individuals, exposure to less than 10 mg/day is unlikely to cause histological changes to the intestinal mucosa. The daily diet of people with celiac disease does not rely solely on gluten-free pre-packaged foods, but also on naturally gluten-free grains (e.g., rice, buckwheat, ...) and foods with grain-derived ingredients (i.e., flour and starches) used for cooking and baking at home. The objective of this study was to estimate the level of incidental gluten potentially present in gluten-free diets from a Canadian perspective. We have conducted gluten exposure estimations from grain-containing foods and foods with grain-derived ingredients, taking into consideration the various rates of food consumption by different sex and age groups. These estimates have concluded that if gluten was present at levels not exceeding 20 ppm, exposure to gluten would remain below 10 mg per day for all age groups studied. However, in reality the level of gluten found in naturally gluten-free ingredients is not static and there may be some concerns related to the flours made from naturally gluten-free cereal grains. It was found that those containing a higher level of fiber and that are frequently used to prepare daily foods by individuals with celiac disease could be a concern. For this category of products, only the flours and starches labelled “gluten-free” should be used for home-made preparations.

Abstract
Background Celiac disease can present in children and adults with a variety of manifestations including a rare complication known as ulcerative jejunitis. The latter has been associated with refractory celiac disease in adult onset patients. The objective of this case report is to describe the first pediatric case of ulcerative jejunitis in celiac disease, diagnosed by capsule endoscopy, which was not associated with refractory celiac disease. Case presentation The 9 year old girl presented with a history of abdominal pain and vomiting. Laboratory investigations revealed a slightly elevated IgA tissue transglutaminase antibody level in the setting of serum IgA deficiency. Initial upper endoscopy with biopsies was not conclusive for celiac disease. Further investigations included positive IgA anti-endomysium antibody, and positive HLA DQ2 typing. Video capsule endoscopy showed delayed appearance of villi until the proximal to mid jejunum and jejunal mucosal ulcerations. Push enteroscopy with biopsies subsequently confirmed the diagnosis of celiac disease and ulcerative jejunitis. Immunohistochemical studies of the intraepithelial lymphocytes and PCR amplification revealed surface expression of CD3 and CD8 and oligoclonal T cell populations. A repeat capsule study and upper endoscopy, 1 year and 4 years following a strict gluten free diet showed endoscopic and histological normalization of the small bowel. Conclusion Ulcerative jejunitis in association with celiac disease has never previously been described in children. Capsule endoscopy was essential to both the diagnosis of celiac disease and its associated ulcerative jejunitis. The repeat capsule endoscopy findings, one year following institution of a gluten free diet, also suggest that ulcerative jejunitis is not always associated with refractory celiac disease and does not necessarily dictate a poor outcome.

Abstract
Malabsorption encompasses dysfunctions occurring during the digestion and absorption of nutrients. A small proportion of patients presents with chronic diarrhoea. A clinical history supportive of malabsorption may guide investigations toward either the small bowel or pancreas. Serological testing for coeliac disease will determine most cases without invasive investigations. In the clinical context of persisting weight loss and malnutrition, small bowel enteropathy may be investigated with small intestinal biopsies. Small bowel absorptive capacity and permeability might be measured by oral sugar-mix ingestion. Further, approaches to the investigation of malabsorption might also involve the detection in faeces of a substance that has not been absorbed. A variation of the latter is the use of breath testing which relies on the breakdown of the malabsorbed test substance by colonic flora. Measurement of protein absorption is difficult and unreliable; it is, therefore, rarely advocated in clinical settings. No single biological marker confirming a diagnosis of small bowel malabsorption or small bowel integrity is presently available in clinical practice. Plasma citrulline concentration, an amino acid not incorporated into endogenous or exogenous proteins, has been extensively used in research studies and supportive results are establishing its concentration as a reliable quantitative biomarker of enterocyte absorptive capacity.

Abstract
The prevalence of celiac disease (CD) among Japanese population has been unknown, whereas it has been increasingly recognized in the US and in the European countries. The aim of the present study is to identify possible cases with CD among Japanese population and clarify the relevance of screening for the disease. We conducted a serologic screening for the disease among 710 Japanese patients and 239 healthy volunteers at a local tertiary teaching hospital, using an anti-tissue transglutaminase IgA (TTG-IgA) test, and histological examination of the small intestines from the TTG-IgA positive subjects. There were no TTG-IgA positive sera among the healthy volunteers. Twenty of the patients (2.8%), including eight with malignant lymphoma, were tested positive for TTG-IgA. The histological examination of the eleven patients among those with positive TTG-IgA, seven showed villous atrophy and partial lymphocytes infiltration in the mucosa, which could be compatible to mucosal changes observed in CD. Five of them had non-Hodgkin lymphoma in the gastrointestinal tracts. Serologic tests using TTG-IgA might be relevant to screen for those with undiagnosed CD among Japanese population.

Abstract
The indication for a small intestinal biopsy is usually the work-up of malabsorption, a clinicopathologic picture caused by a number of infectious and noninfectious inflammatory conditions. The biopsy is generally taken through an endoscope, by either forceps or suction, from the duodenum or proximal jejunum. Depending upon the underlying condition, morphological abnormalities are seen in malabsorption range from normal mucosa with increased intraepithelial lymphocytes (gluten-sensitive enteropathy, viral gastroenteritis, food allergies, etc.), villous shortening with crypt hyperplasia (celiac disease (CD), treated CD, tropical sprue, and bacterial overgrowth), to completely flat mucosa (CD, refractory sprue, enteropathy-induced T-cell lymphoma, and autoimmune enteropathy). Infectious agents that affect gastrointestinal tract can be grouped as food-borne and water-borne bacteria, opportunistic infections (bacterial, fungal, and viral), viral infections (extremely rarely biopsied), and parasitic and helminthic infections. The majority of these infections are, however, self-limited. Although biopsy is more invasive, the use of this procedure allows detection of other causes, including Whipple's disease, other protozoan forms of diarrhea (e.g., cryptosporidiosis, isosporiasis, or cyclosporiasis), Crohn's disease, or lymphoma that may also present as diarrhea and malabsorption.

Abstract
CONTEXT The data on status of apoptosis in patients with celiac disease are conflicting. Furthermore, complex interaction between intrinsic and common apoptotic pathways, apoptotic inhibitors, and epithelial cell proliferation is largely unclear for patients with celiac disease. OBJECTIVES To determine the role of apoptosis and epithelial cell regeneration in celiac disease. DESIGN Twenty-five treatment-naïve patients with celiac disease and 6 patients with functional dyspepsia, as controls, were included and duodenal biopsy specimens from all were subjected to immunohistochemistry with markers of intrinsic apoptotic pathway (AIF, H2AX, p53), common pathway (CC3, M30), apoptotic inhibitors (XIAP, Bcl2), and epithelial proliferation (Ki-67). Apoptotic and proliferation indices were calculated. RESULTS Expression of end-apoptotic products, that is, H2AX in the cell nuclei (P = .01) and M30 in the cell cytoplasm (P < .01), was significantly upregulated in celiac disease in comparison to controls. Cleaved caspase-3 was also upregulated in villous cytoplasm in celiac disease. Apoptotic inhibitor Bcl2 was significantly down-regulated in celiac disease in comparison to controls. In addition, Ki-67 proliferation index was upregulated both in the crypts and villous mucosal epithelium in comparison to the crypts of the controls. CONCLUSIONS Treatment-naïve patients with celiac disease have significantly higher level of apoptosis that involves both the common and intrinsic apoptotic pathways. Increased apoptosis and unequaled cell regeneration in crypts probably results in villous atrophy. Down-regulation of apoptotic inhibitors in treatment-naïve celiac disease imparts an additional pro-apoptotic effect.

Immunohistochemical stains for CD3 and CD8 do not improve detection of gluten-sensitive enteropathy in duodenal biopsies. Mod Pathol 2013; 26:1241-5.

Abstract
Patients with gluten-sensitive enteropathy usually have increased numbers of duodenal intraepithelial lymphocytes even if the villous architecture is normal. Some authors advocate the use of CD8 and CD3 immunohistochemical stains to improve detection of intraepithelial lymphocytosis, yet the added value of immunohistochemistry when biopsies appear normal remains unproven. The purpose of this study was to evaluate the utility of CD3 and CD8 immunostains in detecting intraepithelial lymphocytosis among duodenal biopsies originally interpreted to be normal based on routine evaluation. We identified 200 duodenal biopsies from 172 patients, all of which were accompanied by a clinical question of gluten-sensitive enteropathy. Five well-oriented villi from each biopsy were assessed. Intraepithelial lymphocytes present in hematoxylin and eosin (H&E)-stained slides were counted and compared with the number of CD3 and CD8 immunopositive cells present in the villous epithelium. Results were expressed as the mean number of intraepithelial lymphocytes or immunopositive cells present per 20 villous tip enterocytes. Review of H&E-stained slides revealed a mean of 2.1 ± 0.1 intraepithelial lymphocytes, compared with 3.2 ± 0.1 CD3-positive and 2.1 ± 0.1 CD8-positive intraepithelial cells (P=<0.001 and 1, respectively), although none of the cases displayed sufficient numbers of intraepithelial lymphocytes to be considered abnormal (ie, ≥ 12/20 enterocytes) by any method. The number of intraepithelial lymphocytes detected by H&E evaluation or immunohistochemistry did not correlate with results of serologic studies for markers of gluten sensitivity. We conclude that immunostains for T cell markers do not improve detection of gluten-sensitive enteropathy when H&E-stained sections are normal.

Abstract
Celiac disease (CD) is an immune-mediated enteropathy triggered by the ingestion of cereal gluten proteins. This disorder is associated with imbalances in the gut microbiota composition that could be involved in the pathogenesis of CD. The aim of this study was to characterize the composition and diversity of the cultivable duodenal mucosa-associated bacteria of CD patients and control children. Duodenal biopsy specimens from patients with active disease on a gluten-containing diet (n = 32), patients with nonactive disease after adherence to a gluten-free diet (n = 17), and controls (n = 8) were homogenized and plated on plate count agar, Wilkins-Chalgren agar, brain heart agar, or yeast, Casitone, and fatty acid agar. The isolates were identified by partial 16S rRNA gene sequencing. Renyi diversity profiles showed the highest diversity values for active CD patients, followed by nonactive CD patients and control individuals. Members of the phylum Proteobacteria were more abundant in patients with active CD than in the other child groups, while those of the phylum Firmicutes were less abundant. Members of the families Enterobacteriaceae and Staphylococcaceae, particularly the species Klebsiella oxytoca, Staphylococcus epidermidis, and Staphylococcus pasteuri, were more abundant in patients with active disease than in controls. In contrast, members of the family Streptococcaceae were less abundant in patients with active CD than in controls. Furthermore, isolates of the Streptococcus anginosus and Streptococcus mutans groups were more abundant in controls than in both CD patient groups, regardless of inflammatory status. The findings indicated that the disease is associated with the overgrowth of possible pathobionts that exclude symbionts or commensals that are characteristic of the healthy small intestinal microbiota.

Abstract
BACKGROUND Evaluation of intraepithelial duodenal lymphocytosis (IDL) is important in celiac disease (CD). There is no established cut-off value for increased number of IELs in the bulb.We therefore investigated the relation between IEL counts in the bulb and duodenal specimens in non-celiac subjects. METHODS The number of CD3+ IELs was determined in specimens from the second part of the duodenum and from the bulb in 34 non-celiac subjects. The numbers of IELs in the villus tip and sides were counted and the quotient tip/side was calculated. HLA DQ2/DQ8 and serum antibodies against transglutaminase were analysed. RESULTS The mean number of IELs per 100 enterocytes (95% CI) in specimens was 14.7 (11.8-17.6) in the bulb, and 21.2 (17.0-25.5) in the second part of the duodenum (p<0.01). There was no difference in IEL count or distribution comparing patients carrying or lacking HLA DQ2/DQ8. CONCLUSIONS IEL count in non-celiac, HLA DQ2/DQ8 positive or negative patients is significantly lower in the bulb than in the second part of the duodenum. These findings implicate that the site of biopsy should be taken into account when considering duodenal lymphocytosis.

Abstract
OBJECTIVE Coeliac disease is defined by gluten responsiveness, yet there are few data on gluten challenge (GC) in adults on a gluten-free diet. Lack of data regarding the kinetics of responses to gluten is a limitation in clinical practice and research when GC is performed. DESIGN 20 adults with biopsy-proven coeliac disease participated. The study included two run-in visits followed by a 14-day GC at a randomly assigned dose of 3 or 7.5 g of gluten/day. Study visits occurred 3, 7, 14 and 28 days after starting GC. Duodenal biopsy was performed during the run-in and at days 3 and 14 of GC. Villous height to crypt depth ratio (Vh:Cd) and intraepithelial lymphocyte (IEL) count/100 enterocytes were measured by two pathologists. Antibodies to tissue transglutaminase and deamidated gliadin peptides, lactulose to mannitol ratio (LAMA) and symptoms were assessed at each visit. RESULTS Significant reduction in Vh:Cd (2.2-1.1, p<0.001) and increase in IELs (32.6-51.8, p<0.001) were seen from baseline to day 14. Antibody titres increased slightly from baseline to day 14 of GC but markedly by day 28. LAMA did not change significantly. Gastrointestinal symptoms increased significantly by day 3 and returned to baseline by day 28. No differences were seen between the two gluten doses. CONCLUSIONS 14 day GC at ≥ 3 g of gluten/day induces histological and serological changes in the majority of adults with coeliac disease. These data permit accurate design of clinical trials and indicate that many individuals will meet coeliac diagnostic criteria after a 2-week GC.

Abstract
The existence of mild forms of celiac disease (CD) can make the histology-based diagnosis difficult to reach. Since anti-endomysium (EMA) and anti-tissue transglutaminase (anti-tTG) are detectable in culture supernatants of duodenal biopsies from CD patients, our aim was to assess if this system can support the histology in the diagnostic work-up. A total of 559 suspected CD patients underwent serum EMA/anti-tTG detection, upper endoscopy with duodenal biopsy sampling, histologic analysis, and organ culture to detect EMA/anti-tTG in supernatants. A subgroup of 30 patients with organ culture positive results were put on a gluten-free diet (GFD). Their gluten-dependency was evaluated by the psychological general well-being and beck depression inventory indexes. Statistical analysis was performed by Cohen k inter-test, Friedman test, and Dunn multiple comparison. Two hundred forty-one out of 559 (43.1%) patients showed intestinal villous atrophy, whereas serum and organ culture EMA/anti-tTG were positive in 293/559 (52.4%) and 334/559 (59.7%) patients, respectively. The strength of agreement resulted good for serology vs histology (k = 0.730), good for organ culture vs histology (k = 0.662), and very good for serology vs organ culture (k = 0.852). After 12 months of GFD, psychological general well-being index significantly increased, and beck depression inventory index significantly decreased (P < 0.001 for each one). Data highlight the organ culture system as a useful tool to assist the histology in diagnosing CD, mainly in cases without villous atrophy or in seronegative patients. The marked improvement in quality of life after a GFD further supports the reliability of this system in diagnosing CD.

Abstract
OBJECTIVES Between 1984 and 1996, Sweden experienced an "epidemic" of clinical celiac disease in children <2 years of age, attributed partly to changes in infant feeding. Whether infant feeding affects disease occurrence and/or the clinical presentation remains unknown. We investigated and compared the total prevalence of celiac disease in 2 birth cohorts of 12-year-olds and related the findings to each cohort's ascertained infant feeding. METHODS A 2-phase cross-sectional screening study was performed in which 13 279 children from 2 birth cohorts participated: children born during the epidemic (1993) and children born after the epidemic (1997). Previously diagnosed cases were reported and confirmed. Blood samples were analyzed for serological markers and children with positive values were referred for small intestinal biopsy. Infant feeding practices in the cohorts were ascertained via questionnaires. Prevalence comparisons were expressed as prevalence ratios. RESULTS The total prevalence of celiac disease was 29 in 1000 and 22 in 1000 for the 1993 and 1997 cohorts, respectively. Children born in 1997 had a significantly lower risk of having celiac disease compared with those born in 1993 (prevalence ratio: 0.75; 95% confidence interval: 0.60-0.93; P = .01). The cohorts differed in infant feeding (specifically, in the proportion of infants introduced to dietary gluten in small amounts during ongoing breastfeeding). CONCLUSIONS A significantly reduced prevalence of celiac disease in 12-year-olds indicates an option for disease prevention. Our findings suggest that the present infant feeding recommendation to gradually introduce gluten-containing foods from 4 months of age, preferably during ongoing breastfeeding, is favorable.

Abstract
Background The objective of this study was to compare celiac disease (CD)– specific antibody tests to determine if they could replace jejunal biopsy in patients with a high pretest probability of CD. Methods This retrospective study included sera from 149 CD patients and 119 controls, all with intestinal biopsy. All samples were analyzed for IgA and IgG antibodies against native gliadin (ngli) and deamidated gliadin peptides (dpgli), as well as for IgA antibodies against tissue transglutaminase and endomysium. Results Tests for dpgli were superior to ngli for IgG antibody determination: 68% vs. 92% specificity and 79% vs. 85% sensitivity for ngli and dpgli, respectively. Positive (76% vs. 93%) and negative (72% vs. 83%) predictive values were also higher for dpgli than for ngli. Regarding IgA gliadin antibody determination, sensitivity improved from 61% to 78% with dpgli, while specificity and positive predictive value remained at 97% (P < 0.00001). A combination of four tests (IgA anti-dpgli, IgG anti-dpgli, IgA anti- tissue transglutaminase, and IgA anti-endomysium) yielded positive and negative predictive values of 99% and 100%, respectively and a likelihood ratio positive of 86 with a likelihood ratio negative of 0.00. Omitting the endomysium antibody determination still yielded positive and negative predictive values of 99% and 98%, respectively and a likelihood ratio positive of 87 with a likelihood ratio negative of 0.01. Conclusion Antibody tests for dpgli yielded superior results compared with ngli. A combination of three or four antibody tests including IgA anti-tissue transglutaminase and/or IgA anti- endomysium permitted diagnosis or exclusion of CD without intestinal biopsy in a high proportion of patients (78%). Jejunal biopsy would be necessary in patients with discordant antibody results (22%). With this two-step procedure, only patients with no CD-specific antibodies would be missed.

Abstract
BACKGROUND This study investigated whether a dot immunoassay (DIA) can provide simultaneous detection of anti-tissue transglutaminase (tTG), anti-deamidated gliadin (DG) and total IgA antibodies, as required in the work-up of celiac disease (CD) patients. METHODS Celiac disease patients (n=111) consecutively diagnosed from 2001 to 2011 at the Children's Hospital and Institute of Immunology (Technical University Dresden) were tested for anti-tTG, anti-DG and total IgA by enzyme-linked immunosorbent assay (ELISA) and DIA retrospectively. Blood donors (n=45) and non-CD individuals with low IgA serum levels (n=8) were included as controls. Antibodies to endomysial antigens (EmA) were assessed by indirect immunofluorescence (IIF). RESULTS Four (3.6%) of 111 CD patients demonstrated an IgA deficiency with total IgA below 50 mg/L by ELISA. Total IgA of the 107 IgA-non-deficient CD patients varied from 70 to 6000 mg/L. All four IgA-deficient CD patients were detected by a reduced reaction control of DIA and demonstrated positive anti-tTG or anti-DG IgG by DIA or ELISA. Detection of anti-tTG and anti-DG by DIA and ELISA showed a very good agreement (IgA: κ=0.972, 0.856, respectively; IgG: 0.921, 0.895, respectively). CONCLUSIONS Immunodot assay is a reliable and easy-to-use technique for the detection of IgA-deficient CD patients. Simultaneous assessment of anti-tTG and anti-DG IgA antibodies, and IgA deficiency by DIA can improve the efficacy of CD serology.

Abstract
Small bowel biopsy remains the gold standard for diagnosing celiac disease (CD). Intraepithelial lymphocytosis in the context of villous atrophy is considered a characteristic histologic finding of CD. However, studies have also indicated that the detection of intraepithelial lymphocytosis in the absence of villous atrophy is not specific for CD, having been documented in other small intestinal disorders. This review summarizes key aspects regarding the histopathologic assessment, impact of the site and number of small bowel biopsy samples on diagnosis, old and emerging classifications, and benefit of standardized pathology report in the diagnostic workup of CD.

Abstract
OBJECTIVE Small intestinal biopsy remains the gold standard in diagnosing celiac disease (CD); however, the wide spectrum of histopathological states and differential diagnosis of CD is still a diagnostic problem for pathologists. Recently, Ensari reviewed the literature and proposed an update of the histopathological diagnosis and classification for CD. MATERIALS AND METHODS In this study, the histopathological materials of 54 children in whom CD was diagnosed at our hospital were reviewed to compare the previous Marsh and Modified Marsh-Oberhuber classifications with this new proposal. RESULTS In this study, we show that the Ensari classification is as accurate as the Marsh and Modified Marsh classifications in describing the consecutive states of mucosal damage seen in CD. CONCLUSIONS Ensari's classification is simple, practical and facilitative in diagnosing and subtyping of mucosal pathology of CD.

Abstract
PURPOSE OF REVIEW To describe whether a gluten-free diet (GFD) is indicated in Marsh I gluten-sensitive enteropathy where gastrointestinal symptoms are not present. Arguments are provided to prescribe a GFD to manage extraintestinal symptoms. By contrast, there are not enough reasons to prescribe a GFD to prevent long-term complications. RECENT FINDINGS Population-based and prospective observational studies have found that lymphocytic duodenosis may be due to not just gluten-sensitive enteropathy but also due to other aetiologic factors. Marsh I type lesions may be the cause of iron-deficiency anaemia of unknown aetiology which is reverted by a GFD. A similar effect seems to occur with bone mineralization and hypertransaminasemia. The beneficial influence of a GFD reducing lymphoma and coeliac disease-related mortality remains controversial. SUMMARY An appropriate differential diagnosis of the lymphocytic duodenosis is essential before a GFD is indicated. As a third of patients remained undiagnosed, in spite of genetic study and specific coeliac serology, flow cytometry and transglutaminase antibodies in duodenal tissue may be helpful in establishing gluten-sensitive enteropathy diagnosis. Future studies should assess whether lymphoma risk is reduced by a GFD in Marsh I patients. Also a more precise benefit in bone mineralization in this setting is needed.

Abstract
BACKGROUND & AIMS Celiac disease has been associated with gastrointestinal (GI) cancers in small studies; risks have not been estimated from large populations or based on histopathology analyses. METHODS We examined the risk of GI cancers by using data from cohorts of patients with celiac disease (villous atrophy, Marsh score of 3; n = 28,882) or inflammation (Marsh score of 1-2; n = 12,860); biopsy samples were evaluated at 28 pathology centers. A third cohort included 3705 individuals with latent celiac disease (normal mucosa, but positive serology results). Data were compared with those from an age- and sex-matched population. RESULTS Of patients with celiac disease, 372 developed incident GI cancers; 347 patients with inflammation and 38 with latent celiac disease developed GI cancers. In the first year after diagnosis and initial biopsy, celiac disease was associated with 5.95-fold increase in risk of incident GI cancer (95% confidence interval [CI], 4.64-7.64); the hazard ratio [HR] for inflammation was 9.13 (95% CI, 7.19-11.6) and for latent celiac disease was 8.10 (95% CI, 4.69-14.0). After the first year, patients were at no significant increase in risk for GI cancers; the HR for celiac disease was 1.07 (95% CI, 0.93-1.23), for inflammation it was 1.16 (95% CI, 0.98-1.37), and for latent celiac disease it was 0.96 (95% CI, 0.56-1.66). The absolute risk for any GI cancer in patients with celiac disease was 101/100,000 person-years, with an excess risk of 2/100,000 person-years. CONCLUSIONS Although celiac disease, inflammation, and latent disease all increase risk for GI cancers in the first year after diagnosis, there is no increase in risk thereafter.

Abstract
OBJECTIVE Diagnostic criteria for coeliac disease (CD) from the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) were published in 1990. Since then, the autoantigen in CD, tissue transglutaminase, has been identified; the perception of CD has changed from that of a rather uncommon enteropathy to a common multiorgan disease strongly dependent on the haplotypes human leukocyte antigen (HLA)-DQ2 and HLA-DQ8; and CD-specific antibody tests have improved. METHODS A panel of 17 experts defined CD and developed new diagnostic criteria based on the Delphi process. Two groups of patients were defined with different diagnostic approaches to diagnose CD: children with symptoms suggestive of CD (group 1) and asymptomatic children at increased risk for CD (group 2). The 2004 National Institutes of Health/Agency for Healthcare Research and Quality report and a systematic literature search on antibody tests for CD in paediatric patients covering the years 2004 to 2009 was the basis for the evidence-based recommendations on CD-specific antibody testing. RESULTS In group 1, the diagnosis of CD is based on symptoms, positive serology, and histology that is consistent with CD. If immunoglobulin A anti-tissue transglutaminase type 2 antibody titers are high (>10 times the upper limit of normal), then the option is to diagnose CD without duodenal biopsies by applying a strict protocol with further laboratory tests. In group 2, the diagnosis of CD is based on positive serology and histology. HLA-DQ2 and HLA-DQ8 testing is valuable because CD is unlikely if both haplotypes are negative. CONCLUSIONS The aim of the new guidelines was to achieve a high diagnostic accuracy and to reduce the burden for patients and their families. The performance of these guidelines in clinical practice should be evaluated prospectively.

Abstract
Enteropathy-associated T-cell lymphoma (EATL), an uncommon lymphoma of intestinal intraepithelial T lymphocytes, occurs with a higher frequency in northern Europe due to association with celiac disease. Data on the occurrence of EATL in the Asian population, among whom celiac disease is very rare, are conflicting. This study aimed to characterize EATL encountered in the Chinese population in Hong Kong. Eighteen cases were identified, all fulfilling the criteria of type II rather than classical EATL. The patients, including 13 men and 5 women, had a median age of 62 years. Most presented with small bowel perforation, and there was no history of malabsorption. The clinical course was aggressive, with 14 of 16 patients dying of progressive disease or complications, usually within 1 year. The histologic features were practically identical in all cases. The central zone of the tumor showed ulceration with or without perforation and was characterized by monotonous transmural infiltration of the bowel by small-sized or medium-sized lymphoma cells with few admixed inflammatory cells and no coagulative necrosis. The peripheral zone featured lateral spread of lymphoma cells in the mucosa, accompanied by variable involvement of the submucosa and muscularis. In all cases, there was an intraepithelial lymphocytosis zone contiguous or discontinuous with the peripheral zone, which was characterized by infiltration of the intestinal epithelium by nonatypical small lymphocytes, and not accompanied by other histologic changes of enteropathy. The most common phenotype of the lymphoma cells was CD3+, CD5-, CD4-, CD8+, CD56+, TIA1+, CD30-, and Epstein-Barr virus, and 2 cases showed aberrant expression of CD20. A remarkable finding was that 14 (78%) cases expressed γδ T-cell receptor, and only 6 (33%) expressed αβ T-cell receptor (with 3 cases coexpressing both T-cell receptors and 1 case expressing neither). The immunophenotype of the intraepithelial lymphocytes was either discordant (particularly with respect to CD8 and CD56 expressions) or concordant with the lymphoma cells of the corresponding cases. Thus, this study shows that EATL occurring in the Chinese population is exclusively of type II. In contrast to several studies, intraepithelial lymphocytosis can be consistently demonstrated and this component seems to represent a precursor lesion of EATL rather than a manifestation of celiac disease. In view of the differences in epidemiology and clinicopathologic features, we believe it is justified to separate out type II EATL from the EATL category as a distinct form of lymphoma, for which we propose the designation "monomorphic intestinal T-cell lymphoma."
