Abstract
Background: Celiac disease (CD) is a multifactorial, immune-mediated enteropathic disorder that may occur at any age with heterogeneous clinical presentation. In the last years, unusual manifestations have become very frequent, and currently, it is not so uncommon to diagnose CD in subjects with overweight or obesity, especially in adults; however, little is known in the pediatric population. This systematic review aims to evaluate the literature regarding the association between CD and overweight/obesity in school-age children. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. An electronic database search of articles published in the last 20 years in English was carried out in Web of Sciences, PubMed, and Medline. The quality of the included studies was assessed by using the STrengthening the Reporting of OBservational studies in Epidemiology statement. Results: Of the 1396 articles identified, 9 articles, investigating overweight/obesity in children/adolescents affected by CD or screening CD in children/adolescents with overweight/obesity, met the inclusion criteria. Overall, the results showed that the prevalence of overweight or obesity in school-age children (6-17 years) affected by CD ranged between 3.5% and 20%, highlighting that the coexistence of CD with overweight/obesity in children is not uncommon as previously thought. Conclusion: Although CD has been historically correlated with being underweight due to malabsorption, it should be evaluated also in children with overweight and obesity, especially those who have a familiar predisposition to other autoimmune diseases and/or manifest unusual symptoms of CD.

Abstract
In January 2020, the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) updated its guidelines for the diagnosis of paediatric coeliac disease. The revised ESPGHAN guidelines offer a more streamlined approach to diagnostic pathways for the detection of this disease in children. This article provides an update for clinicians on how to diagnose and manage coeliac disease in children based on the revised guidelines and other available literature.

Abstract
AIM To explore the perceptions and practices of Australasian paediatric gastroenterologists in diagnosing coeliac disease (CD) before and during the COVID-19 pandemic. METHODS Paediatric gastroenterologists in Australasia were invited via email to complete an anonymous online questionnaire over a 2-week period in 2021. RESULTS The questionnaire was completed by 39 respondents: 33 from Australia and six from New Zealand (NZ) equating to a 66% response rate. Thirty-four (87%) of the 39 respondents reported they currently practised non-biopsy diagnosis of CD in eligible children, while the rest diagnosed CD using biopsy confirmation only. All NZ respondents practised non-biopsy CD diagnosis. A majority of responders (76%) who practised non-biopsy CD diagnosis followed the 2020 European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) guidelines. Twenty-two (56%) respondents reported that they started using a non-biopsy CD diagnosis protocol before the pandemic and did not change their practice during the pandemic, 10 (26%) started diagnosing non-biopsy CD during the pandemic, 5 (13%) stated their practices of CD were not impacted by the pandemic and 2 (5%) did not respond on whether the pandemic changed their practice. CONCLUSION The majority of Australasian gastroenterologist respondents reported they routinely utilised the 2020 ESPGHAN diagnostic criteria in eligible children; half of them started prior to the pandemic and another quarter started this approach due to the pandemic. A minority of practitioners routinely rely only on biopsy confirmation to diagnose CD.

Abstract
Many patients report symptoms after wheat ingestion experiencing a wide spectrum of clinical manifestations. Three possible diagnoses have been recognized: celiac disease (CD), wheat allergy (WA), and non-celiac (gluten) wheat sensitivity (NCGS/NCWS). CD is a chronic immune-mediated disease of the small bowel caused by exposure to dietary gluten in genetically predisposed individuals, with a prevalence of approximately 1%. It is characterized by mucosal inflammation and atrophy following exposure to gluten and improvement after gluten withdrawal. Food allergies are immunological responses to a food antigen. WA is the expression of an immunologically mediated process that can be immunoglobulin E (IgE) or non-IgE mediated; its many symptoms include urticaria/angioedema, asthma, rhinitis, and anaphylaxis. NCGS/NCWS is characterized by gastrointestinal and/or extra-intestinal symptoms after ingestion of gluten-containing food in subjects not affected by CD or WA. The aim of this review is to help physicians and nutritionists diagnose the cause of symptoms reported after wheat ingestion, thus avoiding patient frustration, inappropriate testing, and incorrect or missed diagnoses. An algorithm for the diagnostic approach in these patients is provided, to help to diagnose CD, WA, NCGS/NCWS or to identify possible functional disorders as the wheat-sensitive irritable bowel syndrome. A personalized approach, regular follow-up, and the help of a skilled healthcare professional are mandatory for patients with symptoms following wheat ingestion is provided. A gluten-free-diet is often recommended for patients with self-reported gluten/wheat-dependent symptoms; for patients with symptoms similar to those of functional diseases while there is evidence that a low-FODMAP diet could be the first option.

Abstract
Objective Emergency interim guidance from the British Society for Gastroenterology (BSG) states that a no-biopsy strategy is possible to diagnose coeliac disease (CD) in adults with elevated transglutaminase IgA antibody (TGA-IgA) levels. We aimed to determine if the suggested TGA-IgA ≥10× ULN is safe and robust in making the diagnosis in adult patients in Scotland. We also aimed to establish if any important co-diagnoses would be missed if no biopsy was performed. Method All positive coeliac serology results for patients aged >15 years in Scotland in 2016 (Grampian 2019) were accessed. Data were collected on demographics, TGA-IgA titres, D1 sampling, histology and macroscopic findings at upper and lower gastrointestinal (GI) endoscopy. Results 1037/1429 patients with positive serology proceeded to biopsy, of which 796/1037 (76.8%) were diagnosed as CD. A total of 320/322 (99.37%) patients with TGA-IgA ≥10× ULN were diagnosed as CD giving the cut-off a positive predictive value of 99.38%. No significant co-pathology was found at endoscopy in these patients. Conclusion Our results show that a no-biopsy strategy using a cut-off of TGA-IgA ≥10× ULN is safe to diagnose CD and that no important pathology would be missed. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition 2020 and BSG COVID-19 interim guidelines are applicable to adult patients in Scotland.

Time to normalisation of tissue transglutaminase in paediatric coeliac disease is dependent on initial titre and half of patients will normalise within 12 months. Arch Dis Child 2022; 107:660-664. [PMID: 35228203 DOI: 10.1136/archdischild-2021-323250] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Accepted: 01/24/2022] [Indexed: 01/08/2023]
Abstract
BACKGROUND Coeliac disease (CD) is common. Response to a gluten-free diet is assessed through serial measurement of tissue transglutaminase (TTG) antibody titre. However, the relationship of TTG titres to symptoms and the speed of normalisation is poorly understood. METHODS Patients seen in 2020, and under follow-up in the Southampton CD clinic, had blood results, growth measures and symptom data collated. Time to normalisation, predictors of normalisation and relationship of TTG to growth/symptoms were assessed. RESULTS 57 patients were included. All had TTG results from the time of diagnosis and follow-up. All families reported dietary compliance.Median TTG at diagnosis was 100 μ/L (range 0.3-4360), 94.7% of the patients had symptoms compatible with CD. At 6-12 months after diagnosis, the median TTG was 3.8 μ/mL (range 0.3-133). In terms of response, 29 of the 57 patients (50.9%) had a TTG below 4 μ/mL (upper normal limit). A further 25 patients (43.9%) had a TTG<10 times the upper limit of normal. Ten patients (17.5%) had a persistently high TTG (median=8.55 μ/mL, range 4.1-303) after >12 months.TTG at diagnosis was correlated with TTG at 6-12 months, β=0.542, p=0.000016. Patients with TTG<10 times the upper limit of normal at diagnosis group were more likely to have normalised at 6-12 months compared with >10 times normal (85% vs 32.4%, p=0.0015). TTG titres did not correlate with growth measures (Z-scores) at diagnosis or at follow-up. CONCLUSIONS Normalisation of TTG levels occurs within 6-12 months for around half of patients. Higher TTG levels at diagnosis take longer to normalise. The role of compliance is unclear.

Abstract
Background There is a clinical need to develop biomarkers of small bowel damage in coeliac disease and Crohn’s disease. This study evaluated intestinal fatty acid binding protein (iFABP), a potential biomarker of small bowel damage, in children with coeliac disease and Crohn’s disease. Methods The concentration iFABP was measured in plasma and urine of children with ulcerative colitis, coeliac disease, and Crohn’s disease at diagnosis and from the latter two groups after treatment with gluten free diet (GFD) or exclusive enteral nutrition (EEN), respectively. Healthy children (Controls) were also recruited. Results 138 children were recruited. Plasma but not urinary iFABP was higher in patients with newly diagnosed coeliac disease than Controls (median [Q1, Q3] coeliac disease: 2104 pg/mL 1493, 2457] vs Controls: 938 pg/mL [616, 1140], p = 0.001). Plasma or urinary iFABP did not differ between patients with coeliac on GFD and Controls. Baseline iFABP in plasma decreased by 6 months on GFD (6mo GFD: 1238 pg/mL [952, 1618], p = 0.045). By 12 months this effect was lost, at which point 25% of patients with coeliac disease had detectable gluten in faeces, whilst tissue transglutaminase IgA antibodies (TGA) continued to decrease. At diagnosis, patients with Crohn’s disease had higher plasma iFABP levels than Controls (EEN Start: 1339 pg/mL [895, 1969] vs Controls: 938 pg/mL [616, 1140], p = 0.008). iFABP did not differ according to Crohn’s disease phenotype. Induction treatment with EEN tended to decrease (p = 0.072) iFABP in plasma which was no longer different to Controls (EEN End: 1114 pg/mL [689, 1400] vs Controls: 938 pg/mL [616, 1140], p = 0.164). Plasma or urinary iFABP did not differ in patients with ulcerative colitis from Controls (plasma iFABP, ulcerative colitis: 1309 pg/mL [1005, 1458] vs Controls: 938 pg/mL [616, 1140], p = 0.301; urinary iFABP ulcerative colitis: 38 pg/mg [29, 81] vs Controls: 53 pg/mg [27, 109], p = 0.605). Conclusions Plasma, but not urinary iFABP is a candidate biomarker with better fidelity in monitoring compliance during GFD than TGA. The role of plasma iFABP in Crohn’s disease is promising but warrants further investigation. Trial registration: Clinical Trials.gov, NCT02341248. Registered on 19/01/2015.

Evaluation of Celiac Disease by Minimally Invasive Biomarkers in a Spanish Pediatric Population. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19095020. [PMID: 35564413 PMCID: PMC9100138 DOI: 10.3390/ijerph19095020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Revised: 04/13/2022] [Accepted: 04/14/2022] [Indexed: 02/04/2023]
Abstract
Background: The diagnosis of celiac disease (CD) has been substantially improved with the availability of highly sensitive CD-specific IgA-TG2, Ig-GDP, and IgA-EMA. The European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) published (2012) and updated (2020) diagnostic criteria for CD in order to simplify CD diagnosis and to avoid biopsies in selected patients. Methods: A prospective study including 5641 pediatric patients (0–16 years old) from January 2012 to January 2019 was performed. CD diagnosis was made according to the ESPGHAN algorithm. The objective of this study was to evaluate the utility of biomarkers and the relationship between TGA-IgA and EMA titers. Results: CD diagnoses were confirmed in 113 patients, 110 were IgA-TG2-positive and 3 (2.7%) had IgA deficiency. The diagnosis was made by serologic tests in 95 (84.1%) patients. Only 18 (15.9%) patients underwent intestinal biopsy. We obtained 100% concordance between IgA-EMA and positive results for IgA-TG2 ≥ 10 ULN with IgA-EMA antibody titer ≥ 1:80. Conclusions: This study provides evidence of a positive correlation between IgA-TG2 antibody serum levels and IgA-EMA. The diagnosis could be guaranteed with strict application of IgA-TG2 values ≥ 10 ULN (confirmed by subsequent testing) plus the serological response to the gluten-free diet (GFD).

Abstract
BACKGROUND There is growing support for a biopsy avoidant approach to diagnose coeliac disease in both children and adults, using a serological diagnosis instead. AIMS To assess the diagnostic accuracy of serological tests for coeliac disease in adults and children. METHODS Seven electronic databases were searched between January 1990 and August 2020. Eligible diagnostic studies evaluated the accuracy of serological tests for coeliac disease against duodenal biopsy. Risk of bias assessment was performed using QUADAS-2. Bivariate random-effects meta-analyses were used to estimate serology sensitivity and specificity at the most commonly reported thresholds. RESULTS 113 studies (n = 28,338) were included, all in secondary care populations. A subset of studies were included in meta-analyses due to variations in diagnostic thresholds. Summary sensitivity and specificity of immunoglobulin A (IgA) anti-tissue transglutaminase were 90.7% (95% confidence interval: 87.3%, 93.2%) and 87.4% (84.4%, 90.0%) in adults (5 studies) and 97.7% (91.0%, 99.4%) and 70.2% (39.3%, 89.6%) in children (6 studies); and of IgA endomysial antibodies were 88.0% (75.2%, 94.7%) and 99.6% (92.3%, 100%) in adults (5 studies) and 94.5% (88.9%, 97.3%) and 93.8% (85.2%, 97.5%) in children (5 studies). CONCLUSIONS Anti-tissue transglutaminase sensitivity appears to be sufficient to rule out coeliac disease in children. The high specificity of endomysial antibody in adults supports its use to rule in coeliac disease. This evidence underpins the current development of clinical guidelines for a serological diagnosis of coeliac disease. Studies in primary care are needed to evaluate serological testing strategies in this setting.

Abstract
BACKGROUND Recently published paediatric guidelines for diagnosing coeliac disease do not include recommendations on the follow-up of coeliac disease patients. GOAL The aim of this study was to assess the management practices and experience of coeliac disease patients with their follow-up appointments in Central Europe. STUDY Gastroenterologists and coeliac disease patients in five Central European countries were asked to complete the web-based questionnaire focusing on coeliac disease management practices. RESULTS Answers from 147 gastroenterologists and 2041 coeliac disease patients were available for the analysis. More than half of the gastroenterologists (58.5%) schedule the first follow-up visit within 3 months after the diagnosis. At follow-up, tissue transglutaminase antibodies are checked in almost all patients (95.9%). Approximately two-thirds (60.7%) of gastroenterologists refer all of their patients to the dietitian at diagnosis. Similarly, 42.8% of coeliac disease patients reported that they had not been appointed to a dietitian. Almost one-third of coeliac disease patients (30.8%) reported that they had no follow-up appointments with gastroenterologist at all. CONCLUSIONS Follow-up of coeliac disease patients is suboptimal in Central Europe. Many patients are not followed regularly. A lot of patients are not referred to a dietitian. The recommendations on the optimal follow-up of coeliac disease patients are needed in order to improve patient care.

Abstract
BACKGROUND The application of the European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) celiac disease (CeD) guidelines by pediatric gastroenterologists in Australia and New Zealand (Australasia) is unknown. Similarly, long-term management practices for patients with CeD are also unknown in this region. AIMS This study aimed to explore the perceptions and practices of Australasian pediatric gastroenterologists in diagnosing and managing patients with CeD. METHODS Australasian pediatric gastroenterologists and trainees were invited to complete an anonymous online survey over a 3-week period. RESULTS The survey was completed by 28 respondents, 24 from Australia and four from New Zealand. Tissue transglutaminase antibody IgA was the most frequently ordered initial serologic test. Fifteen (54%) respondents relied on duodenal biopsies for the confirmation of CeD, six (21%) followed the ESPGHAN guidelines and the remaining seven offered either biopsy confirmation or no-biopsy diagnosis according to the parents' wishes. Following diagnosis, five (18%) respondents discharged patients from care, three (11%) discharged patients after one follow-up visit, one (4%) reviewed patients for 12 months, six (21%) reviewed patients until celiac antibodies normalized and children were clinically asymptomatic, and 13 (46%) reviewed patients until transition to adult care. CONCLUSION Tissue transglutaminase antibody IgA was the most common initial serologic test ordered by this group of Australasian pediatric gastroenterologists. Half of these physicians rely solely on duodenal biopsy for the confirmation of CeD diagnosis: a minority routinely use the ESPGHAN guidelines. Physicians reported a wide range of CeD follow-up practices.

Abstract
BACKGROUND Celiac disease is a common disorder but there are few studies comparing the clinical features of the disease in adults, adolescents and children. METHODS Demographic and clinical characteristics of all patients with celiac disease referred to the Celiac Clinic were evaluated and compared in different age groups. RESULTS Of 3416 participants, 473 patients were included. 302 (63.8%) were women and 171 (36.2%) were men. Overall, 325 (68.7%) and 411 (86.9%) patients had gastrointestinal (GI) and non-GI manifestations, respectively. The most common symptom in adults was psychiatric problems (66.5%), while abdominal discomfort was the most common symptom in adolescents (45.2%) and children (53.8%). According to age groups, GI manifestations were seen in 79 (66.4%), 119 (59.8%), and 127 (81.9%) children, adolescents, and adults, respectively. Adults had significantly more GI manifestations than the other groups (PR 1.167; 95% CI: 1.094- 1.244; p < 0.001). Non-GI manifestations were seen in 90 (75.6%), 174 (87.4%), and 147 (94.8%) children, adolescents, and adults, respectively. Adults had significantly more non-GI manifestations than the other groups (PR 1.112; 95% CI: 1.060-1.168; p < 0.001). CONCLUSION Our study showed that there were significant differences in the clinical features of celiac disease between the different age groups. Considering these results may help plan for future studies.

Abstract
Coeliac disease (CD) is an autoimmune gluten-dependent condition with a prevalence of 1% in the population, if screened. However, approximately only a third of children with CD are diagnosed. When CD is suspected, serological screening with anti-tissue transglutaminase titres should be performed. Children with a positive result should be referred to a specialist in CD for confirmation of the diagnosis. The European Society for Paediatric Gastroenterology Hepatology and Nutrition revised their diagnostic guidance for CD in 2020 and this article discusses the current diagnostic pathways. Lifelong strict adherence to a gluten-free diet is necessary to prevent complications. Nurses and specialist paediatric dietitians have an important role in recognising and diagnosing CD early, as well as offering ongoing dietary and clinical support.

Abstract
BACKGROUND Rotavirus infection has been proposed as a risk factor for coeliac disease (CD) and type 1 diabetes (T1D). The UK introduced infant rotavirus vaccination in 2013. We have previously shown that rotavirus vaccination can have beneficial off-target effects on syndromes, such as hospitalised seizures. We therefore investigated whether rotavirus vaccination prevents CD and T1D in the UK. METHODS A cohort study of children born between 2010 and 2015 was conducted using primary care records from the Clinical Practice Research Datalink. Children were followed up from 6 months to 7 years old, with censoring for outcome, death or leaving the practice. CD was defined as diagnosis of CD or the prescription of gluten-free goods. T1D was defined as a T1D diagnosis. The exposure was rotavirus vaccination, defined as one or more doses. Mixed-effects Cox regression was used to estimate hazard ratios (HR) and 95% confidence intervals (CIs). Models were adjusted for potential confounders and included random intercepts for general practices. RESULTS There were 880,629 children in the cohort (48.8% female). A total of 343,113 (39.0%) participants received rotavirus vaccine; among those born after the introduction of rotavirus vaccination, 93.4% were vaccinated. Study participants contributed 4,388,355 person-years, with median follow-up 5.66 person-years. There were 1657 CD cases, an incidence of 38.0 cases per 100,000 person-years. Compared with unvaccinated children, the adjusted HR for a CD was 1.05 (95% CI 0.86-1.28) for vaccinated children. Females had a 40% higher hazard than males. T1D was recorded for 733 participants, an incidence of 17.1 cases per 100,000 person-years. In adjusted analysis, rotavirus vaccination was not associated with risk of T1D (HR = 0.89, 95% CI 0.68-1.19). CONCLUSIONS Rotavirus vaccination has reduced diarrhoeal disease morbidity and mortality substantial since licencing in 2006. Our finding from this large cohort study did not provide evidence that rotavirus vaccination prevents CD or T1D, nor is it associated with increased risk, delivering further evidence of rotavirus vaccine safety.

Abstract
INTRODUCTION Children and adolescents with type 1 diabetes mellitus (T1DM) are at high risk for the development of celiac disease (CD) because of the common genetic characteristics of both conditions. The study objectives were to investigate the frequency of the human leukocyte antigen system (HLA) for CD in pediatric T1DM patients and to determine whether HLA testing is suitable for CD screening in that population and is cost-effective as compared to serological screening for CD. PATIENTS AND METHODS A retrospective, descriptive study was conducted in 296 patients (148 girls; 148 boys) with T1DM aged <18 years who attended a Madrid hospital. Data on the frequency of genotypes DQ2/DQ8 in a subgroup of 92 patients and the additional cost of performing HLA typing for screening CD were collected. Only when the risk HLA haplotype (DQ2/DQ8) is negative no further serological screening for CD is required. RESULTS Twenty-three patients with T1DM (7.77%) also had CD. Alleles DQ2 or DQ8 were found in 91.3% of patients in whom the HLA haplotype was studied. Thus, only 8.7% with a negative haplotype would have benefited from HLA testing. The additional cost of HLA typing was € 105.2 for each patient with positive DQ2 or DQ8 in our population. CONCLUSIONS HLA typing is not a cost-effective screening method for CD in T1DM because of the frequent association of T1DM with risk genotypes for CD.

Is duodenal biopsy always necessary for the diagnosis of coeliac disease in adult patients with high anti-tissue transglutaminase (TTG) antibody titres? Frontline Gastroenterol 2021; 13:287-294.

Abstract
OBJECTIVE Avoiding duodenal biopsy in adults for coeliac disease (CD) diagnosis is controversial. Some retrospective and prospective studies have shown that CD can be reliably diagnosed in adults with serology rather than duodenal biopsies. This study aimed to check the accuracy of a cut-off value of ≥10 upper limit of normal of anti-tissue transglutaminase antibody (anti-TTG IgA) titres for CD diagnosis in adult patients. METHOD We retrospectively analysed adult patients (≥16 years) who underwent gastroscopy from 2013 to 2018 for positive coeliac serology. The relationship between titres and disease was determined by using linear models, whereas sensitivity and specificity were assessed by receiver operator curve. RESULTS We analysed 144 newly anti-TTG antibody-positive adult patients with a median age of 48.5 years (IQR 32-62); among them, 86 (60%) patients had CD (Marsh III: n=68 and Marsh II and I: n=18) with a higher prevalence in females (n=59 (69%)) and Europeans (n=60 (70%)). Fifty (58%) patients with CD had colonoscopy and five (6%) had imaging; only six patients were diagnosed with additional conditions. An anti-TTG IgA titre cut-off value of 150 U/L was 100% specific for CD in our dataset, with 70% (95% CI: 60% to 88%) sensitivity for this patient group. CONCLUSION Coeliac serology using anti-TTG IgA with titres ≥10× normal value is an excellent predictor of CD, irrespective of age, gender and ethnicity. Duodenal biopsy may not be necessary in selected adult patients with CD, especially younger than 50 years of age without additional gastrointestinal red-flag signs and symptoms.

Abstract
OBJECTIVES The 2012 European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) guidelines on celiac disease (CD) recommended a no-biopsy pathway (NBP) for symptomatic children with high immunoglobin A (IgA)-based anti-tissue transglutaminase (TGA-IgA) titers, positive anti-endomysial antibody and human leukocyte antigen (HLA)-DQ2/DQ8 status. We aimed to understand variations in practice amongst specialist pediatric gastroenterology centers (SPGIC) in the United Kingdom (UK). METHODS A survey questionnaire was sent to all UK SPGIC (n = 29) providing endoscopy services for CD diagnosis. It was divided into four main subgroups: analyzing diagnosis of CD through adherence to the ESPGHAN (2012) guidelines, post-diagnosis care and long-term follow-up and discharge from pediatric services. RESULTS All 29 responded. NBP was implemented in 28 of 29 centers. Five of 29 centers had already stopped HLA-DQ2/DQ8 testing for NBP diagnosis. Twenty six of 29 centers were performing endoscopy on screening-identified children (mostly asymptomatic, "at-risk" patients). Diagnosis was communicated by a doctor in 65% SPGIC (n = 19). Most centers (n = 23) waited 6-12 months post-diagnosis to start gluten-free oats. Routine vitamin D supplementation was commenced by 4 of 29 centers. All centers repeated TGA-IgA to assess normalization but at varying times post-GFD. Follow-up was with a combination of doctors/dieticians (n = 26). Eleven of 29 centers discharged their patient to primary care. CONCLUSIONS There was excellent uptake of ESPGHAN guidelines (2012) in the UK and adherence to guidelines is generally good. Despite published evidence and pragmatic advice from the British Society of Paediatric Gastroenterology Hepatology and Nutrition and National Institute for Health and Care Excellence, significant differences remain in diagnostic and ongoing management practice and are opportunities for research and directive evidence-based follow-up guidance.

Abstract
Celiac disease (CD) is characterized by clinical polymorphism, with classic, asymptomatic or oligosymptomatic, and extra-intestinal forms, which may lead to diagnostic delay and exposure to serious complications. CD is a multidisciplinary health concern involving general medicine, pediatric, and adult gastroenterology, among other disciplines. Immunology and pathology laboratories have a fundamental role in diagnosing and monitoring CD. The diagnosis consists of serological testing based on IgA anti-transglutaminase (TG2) antibodies combined with IgA quantification to rule out IgA deficiency, a potential misleading factor of CD diagnosis. Positive TG2 serology should be corroborated by anti-endomysium antibody testing before considering an intestinal biopsy. Owing to multiple differential diagnoses, celiac disease cannot be confirmed based on serological positivity alone, nor on isolated villous atrophy. In children with classical signs or even when asymptomatic, with high levels of CD-linked markers and positive HLA DQ2 and/or DQ8 molecules, the current trend is to confirm the diagnosis on basis of the non-systematic use of the biopsy, which remains obligatory in adults. The main challenge in managing CD is the implementation and compliance with a gluten-free diet (GFD). This explains the key role of the dietitian and the active participation of patients and their families throughout the disease-management process. The presence of the gluten in several forms of medicine requires the sensitization of physicians when prescribing, and particularly when dispensing gluten-containing formulations by pharmacists. This underlines the importance of the contribution of the pharmacist in the care of patients with CD within the framework of close collaboration with physicians and nutritionists.

Abstract
INTRODUCTION In coeliac disease (CD) micronutrient deficiencies may occur due to malabsorption in active disease and diminished intake during treatment with a gluten-free diet (GFD). This study assessed the micronutrient status in children with CD at diagnosis and follow-up. METHODS Fifteen micronutrients were analysed in 106 blood samples from newly diagnosed CD and from patients on a GFD for <6 months, 6-12 months and with longstanding disease (>12 months). Predictors of micronutrient status included: demographics, disease duration, anthropometry, gastrointestinal symptoms, raised tissue transglutaminase antibodies (TGA), multivitamin use and faecal gluten immunogenic peptide (GIP). Micronutrient levels were compared against laboratory reference values. RESULTS At CD diagnosis (n = 25), low levels in ≥10% of patients were observed for: vitamins E (88%), B1 (71%), D (24%), K (21%), A (20%) and B6 (12%), ferritin (79%), and zinc (33%). One year post-diagnosis, repletion of vitamins E, K, B6 and B1 was observed (<10% patients). In contrast, deficiencies for vitamins D, A and zinc did not change significantly post-diagnosis. Copper, selenium and magnesium did not differ significantly between diagnosis and follow-up. All samples for B2, folate, vitamin C (except for one sample) and B12 were normal. A raised TGA at follow-up was associated with low vitamins A and B1 (raised vs normal TGA; vitamin A: 40% vs 17%, p = 0.044, vitamin B1: 37% vs 13%, p = 0.028). Low vitamin A (p = 0.009) and vitamin D (p = 0.001) were more common in samples collected during winter. There were no associations between micronutrient status with GIP, body mass index, height, socioeconomic status, or gastrointestinal symptom. Multivitamin use was less common in patients with low vitamin D. CONCLUSIONS Several micronutrient deficiencies in CD respond to a GFD but others need to be monitored long-term and supplemented where indicated.

Abstract
Diarrhea in the pediatric solid organ transplantation (SOT) recipient is a frequent complaint that is associated with significant morbidity and impaired quality of life. There are limited published data regarding the specific epidemiology, diagnostic evaluation, and treatment of diarrhea after SOT in children. Pediatric SOT recipients have an increased risk of developing diarrhea because of a generalized immunosuppressed state, epidemiologic exposures, and polypharmacy. There is a need to standardize the diagnostic evaluation of diarrhea in children after SOT to facilitate an accurate diagnosis and timely treatment. Herein, we review the available published data and propose a systematic, stepwise approach to the evaluation of diarrhea in this high-risk population, focusing on timely diagnosis of both infectious and non-infectious causes, in order to provide focused management. Prospective studies are needed to better assess the true prevalence, risk factors for, etiologies, and complications of diarrhea in pediatric SOT patients that will guide optimal management. Development of effective vaccines and antiviral therapies for enteric viruses may also contribute to improved outcomes.

Classification of intestinal T-cell receptor repertoires using machine learning methods can identify patients with coeliac disease regardless of dietary gluten status. J Pathol 2021; 253:279-291.

Abstract
In coeliac disease (CeD), immune-mediated small intestinal damage is precipitated by gluten, leading to variable symptoms and complications, occasionally including aggressive T-cell lymphoma. Diagnosis, based primarily on histopathological examination of duodenal biopsies, is confounded by poor concordance between pathologists and minimal histological abnormality if insufficient gluten is consumed. CeD pathogenesis involves both CD4+ T-cell-mediated gluten recognition and CD8+ and γδ T-cell-mediated inflammation, with a previous study demonstrating a permanent change in γδ T-cell populations in CeD. We leveraged this understanding and explored the diagnostic utility of bulk T-cell receptor (TCR) sequencing in assessing duodenal biopsies in CeD. Genomic DNA extracted from duodenal biopsies underwent sequencing for TCR-δ (TRD) (CeD, n = 11; non-CeD, n = 11) and TCR-γ (TRG) (CeD, n = 33; non-CeD, n = 21). We developed a novel machine learning-based analysis of the TCR repertoire, clustering samples by diagnosis. Leave-one-out cross-validation (LOOCV) was performed to validate the classification algorithm. Using TRD repertoire, 100% (22/22) of duodenal biopsies were correctly classified, with a LOOCV accuracy of 91%. Using TCR-γ (TRG) repertoire, 94.4% (51/54) of duodenal biopsies were correctly classified, with LOOCV of 87%. Duodenal biopsy TRG repertoire analysis permitted accurate classification of biopsies from patients with CeD following a strict gluten-free diet for at least 6 months, who would be misclassified by current tests. This result reflects permanent changes to the duodenal γδ TCR repertoire in CeD, even in the absence of gluten consumption. Our method could complement or replace histopathological diagnosis in CeD and might have particular clinical utility in the diagnostic testing of patients unable to tolerate dietary gluten, and for assessing duodenal biopsies with equivocal features. This approach is generalisable to any TCR/BCR locus and any sequencing platform, with potential to predict diagnosis or prognosis in conditions mediated or modulated by the adaptive immune response. © 2020 The Authors.

Abstract
The Indian Association of Pathologists and Microbiologists (IAPM) and Indian Society of Gastroenterology (ISG) decided to make a joint consensus recommendation for handling, processing, and interpretation of SI biopsies for the diagnosis and management of celiac disease (CD) recognizing the inhomogeneous practice of biopsy sampling, orientation, processing, and interpretation. A modified Delphi process was used to develop this consensus document containing a total of 42 statements and recommendations, which were generated by sharing the document draft, incorporating expert's opinion, followed by three cycles of electronic voting as well as a full-day face-to-face virtual ZOOM meeting and review of supporting literature. Of the 42 statements, 7 statements are on small intestinal (SI) biopsy in suspected patients of CD, site and the number of biopsies; 7 on handling, fixative, orientation, processing, and sectioning in pathology laboratories; 2 on histological orientation; 13 statements on histological interpretation and histological grading; 3 on the assessment of follow-up biopsies; 2 statements on gluten-free diet (GFD)-nonresponsive CD; 4 on challenges in the diagnosis of CD; 2 statements each on pathology reporting protocol and training and infrastructure in this area. The goal of this guideline document is to formulate a uniform protocol agreed upon both by the experienced pathologists and gastroenterologists to standardize the practice, improve the yield of small bowel biopsy interpretation, patients' compliance, overall management in CD, and generate unified data for patient care and research in the related field.

Alterations in Intestinal Microbiota of Children With Celiac Disease at the Time of Diagnosis and on a Gluten-free Diet. Gastroenterology 2020; 159:2039-2051.e20. [PMID: 32791131 PMCID: PMC7773982 DOI: 10.1053/j.gastro.2020.08.007] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Revised: 07/15/2020] [Accepted: 08/02/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND AND AIMS It is not clear whether alterations in the intestinal microbiota of children with celiac disease (CD) cause the disease or are a result of disease and/or its treatment with a gluten-free diet (GFD). METHODS We obtained 167 fecal samples from 141 children (20 with new-onset CD, 45 treated with a GFD, 57 healthy children, and 19 unaffected siblings of children with CD) in Glasgow, Scotland. Samples were analyzed by 16S ribosomal RNA sequencing, and diet-related metabolites were measured by gas chromatography. We obtained fecal samples from 13 children with new-onset CD after 6 and 12 months on a GFD. Relationships between microbiota with diet composition, gastrointestinal function, and biomarkers of GFD compliance were explored. RESULTS Microbiota α diversity did not differ among groups. Microbial dysbiosis was not observed in children with new-onset CD. In contrast, 2.8% (Bray-Curtis dissimilarity index, P = .025) and 2.5% (UniFrac distances, P = .027) of the variation in microbiota composition could be explained by the GFD. Between 3% and 5% of all taxa differed among all group comparisons. Eleven distinctive operational taxonomic units composed a microbe signature specific to CD with high diagnostic probability. Most operational taxonomic units that differed between patients on a GFD with new-onset CD vs healthy children were associated with nutrient and food group intake (from 75% to 94%) and with biomarkers of gluten ingestion. Fecal levels of butyrate and ammonia decreased during the GFD. CONCLUSIONS Although several alterations in the intestinal microbiota of children with established CD appear to be effects of a GFD, specific bacteria were found to be distinct biomarkers of CD. Studies are needed to determine whether these bacteria contribute to pathogenesis of CD.

Abstract
BACKGROUND Environmental enteropathy is an example of a poorly-understood intestinal disorder affecting millions of children worldwide, characterized by malabsorption and stunting. Although there is increasing interest in non-invasive means of assessing intestinal structure and function, the potential value of intestinal biopsy for histology, immunostaining, RNA sequencing and epigenetic work means that endoscopic biopsy remains extremely valuable. We here report our experience in the BEECH (Biomarkers of Environmental Enteropathy in CHildren) study of stunting in Zambia, in the belief that it may help address the knowledge gap regarding the safety of endoscopic biopsy in vulnerable young children. METHODS We report our experience of safety in 119 children undergoing endoscopic biopsy in the BEECH study in Lusaka Children's Hospital, Lusaka, and discuss ethical considerations in this light. RESULTS Upper gastrointestinal endoscopy was performed on children with stunting (length-for-age z score -2 or less) not responsive to nutritional interventions. Conscious sedation was provided by anaesthetists. Of 119 children, 5 (4%) developed transient desaturation, but no serious adverse events were experienced; no clinical, demographic or anaesthetic characteristics were identified as predictive of desaturation. Two children derived clinically useful information from the endoscopy, one life-saving. Of 105 lactase tests, 59 (54%) showed hypolactasia. DISCUSSION Children with stunting underwent endoscopy safely, and some derived clinical benefit. Safety and the possibility of clinical benefit are usually felt to be preconditions for the ethical justification for endoscopy for research in children, and we believe that these conditions were met in this study.

Abstract
Coeliac disease (CD) is an autoimmune condition, characterised by an immunological response to ingestion of gluten in genetically susceptible individuals, affecting about 1% of the population in many regions of the world. Increased knowledge regarding the pathogenesis, improved diagnostic techniques and increased awareness over the years have transformed our understanding of CD such that it is no longer a rare enteropathy, but rather a common multisystem disorder which affects individuals of all ages and results in wide-ranging clinical manifestations. Only a minority of children now present with the classical clinical picture of profound diarrhoea and malnutrition. An increasing number of children with CD present with either mild, non-specific gastrointestinal symptoms or extra-intestinal manifestations or even be asymptomatic, as in many screening-detected children. Knowledge about these diverse manifestations and a high index of suspicion is essential so that appropriate investigations can be undertaken, diagnosis established and treatment initiated. Although traditionally small bowel biopsy is considered essential for the diagnosis, recent guidelines from various professional bodies have paved the way to a biopsy-free diagnosis in a subset of symptomatic children. Life long, strict gluten-free diet still remains the only effective treatment at present, although several novel therapeutic agents are in various phases of clinical trials.

Abstract
INTRODUCTION Coeliac disease (CD) is a systemic immune-mediated disorder triggered by gluten in genetically predisposed individuals. CD is diagnosed using a combination of serology tests and endoscopic biopsy of the small intestine. However, because of non-specific symptoms and heterogeneous clinical presentation, diagnosing CD is challenging. Early detection of CD through improved case-finding strategies can improve the response to a gluten-free diet, patients' quality of life and potentially reduce the risk of complications. However, there is a lack of consensus in which groups may benefit from active case-finding. METHODS AND ANALYSIS We will perform a systematic review to determine the accuracy of diagnostic indicators (such as symptoms and risk factors) for CD in adults and children, and thus can help identify patients who should be offered CD testing. MEDLINE, Embase, Cochrane Library and Web of Science will be searched from 1997 until 2020. Screening will be performed in duplicate. Data extraction will be performed by one and checked by a second reviewer. Disagreements will be resolved through discussion or referral to a third reviewer. We will produce a narrative summary of identified prediction models. Studies, where 2×2 data can be extracted or reconstructed, will be treated as diagnostic accuracy studies, that is, the diagnostic indicators are the index tests and CD serology and/or biopsy is the reference standard. For each diagnostic indicator, we will perform a bivariate random-effects meta-analysis of the sensitivity and specificity. ETHICS AND DISSEMINATION Results will be reported in peer-reviewed journals, academic and public presentations and social media. We will convene an implementation panel to advise on the optimum strategy for enhanced dissemination. We will discuss findings with Coeliac UK to help with dissemination to patients. Ethical approval is not applicable, as this is a systematic review and no research participants will be involved. PROSPERO REGISTRATION NUMBER CRD42020170766.

Sharp SA, Jones SE, Kimmitt RA, Weedon MN, Halpin AM, Wood AR, Beaumont RN, King S, van Heel DA, Campbell PM, Hagopian WA, Turner JM, Oram RA. A single nucleotide polymorphism genetic risk score to aid diagnosis of coeliac disease: a pilot study in clinical care. Aliment Pharmacol Ther 2020; 52:1165-1173. [PMID: 32790217 DOI: 10.1111/apt.15826] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 01/05/2020] [Accepted: 05/10/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Single nucleotide polymorphism-based genetic risk scores (GRS) model genetic risk as a continuum and can discriminate coeliac disease but have not been validated in clinic. Human leukocyte antigen (HLA) DQ gene testing is available in clinic but does not include non-HLA attributed risk and is limited by discrete risk stratification. AIMS To accurately characterise both HLA and non-HLA coeliac disease genetic risk as a single nucleotide polymorphism-based GRS and evaluate diagnostic utility. METHODS We developed a 42 single nucleotide polymorphism coeliac disease GRS from a European case-control study (12 041 cases vs 12 228 controls) using HLA-DQ imputation and published genome-wide association studies. We validated the GRS in UK Biobank (1237 cases) and developed direct genotyping assays. We tested the coeliac disease GRS in a pilot clinical cohort of 128 children presenting with suspected coeliac disease. RESULTS The GRS was more discriminative of coeliac disease than HLA-DQ stratification in UK Biobank (receiver operating characteristic area under the curve [ROC-AUC] = 0.88 [95% CIs: 0.87-0.89] vs 0.82 [95% CIs: 0.80-0.83]). We demonstrated similar discrimination in the pilot clinical cohort (114 cases vs 40 controls, ROC-AUC = 0.84 [95% CIs: 0.76-0.91]). As a rule-out test, no children with coeliac disease in the clinical cohort had a GRS below 38th population centile. CONCLUSIONS A single nucleotide polymorphism-based GRS may offer more effective and cost-efficient testing of coeliac disease genetic risk in comparison to HLA-DQ stratification. As a comparatively inexpensive test it could facilitate non-invasive coeliac disease diagnosis but needs detailed assessment in the context of other diagnostic tests and against current diagnostic algorithms.

An updated overview of spectrum of gluten-related disorders: clinical and diagnostic aspects. BMC Gastroenterol 2020; 20:258. [PMID: 32762724 PMCID: PMC7409416 DOI: 10.1186/s12876-020-01390-0] [Citation(s) in RCA: 42] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2020] [Accepted: 07/21/2020] [Indexed: 02/06/2023] Open
Abstract
The incidence of gluten-related disorders (GRDs) continues to increase and its global prevalence is estimated at approximately 5% of the population. Celiac disease (CD), dermatitis herpetiformis (DH), gluten ataxia (GA), wheat allergy (WA), and non-celiac gluten sensitivity (NCGS) are the five major GRDs that present with a wide range of clinical manifestations. The diagnosis of GRDs can be challenging because the typical and atypical clinical manifestations of the GRDs overlap. In this review, the current definitions of gluten-related disorders, focusing on their clinical features, diagnostic and therapeutic approaches are presented. We concluded that GRDs are usually diagnosed using a combination of clinical features, serological tests, and histopathological findings. Treatment usually involves dietary modification.

An Overview of International Guidelines Focusing on the Long-Term Management of Coeliac Disease. GASTROINTESTINAL DISORDERS 2020.

Abstract
Coeliac disease (CD) is an autoimmune disorder characterised by, but not isolated to, intestinal enteropathy in response to exposure to gluten in predisposed individuals. The mainstay of the management of CD is a strict, lifelong gluten free diet (GFD). Although numerous publications have focused on pathways to guide the diagnosis of CD, recommendations for the care of patients after diagnosis are less well established. This manuscript aimed to review the available published guidelines focusing on the ongoing management and follow-up of patients after diagnosis with CD and commencement of a GFD. All available guidelines recommend strict adherence to a GFD with most recommending an annual review by a specialist clinician, focusing on symptoms, adherence and growth. In addition to monitoring micronutrient status, some guidelines suggest monitoring bone mineral density in at-risk groups and screening for other autoimmune disorders. The benefit of multi-disciplinary input was outlined in many guidelines, in particular, the involvement of a specialist dietitian to provide nutritional counselling and support. While the available guidelines provide key messages, they highlight a lack of strong evidence and some inconsistences. Further evidence is required to support high quality, best-practice management strategies that will optimise the outcomes of patients with CD.

Abstract
The fatty acid-binding proteins play a major role in intracellular transportation of long-chain fatty acids. Nine fatty acid-binding proteins have been identified, with each having individual tissue-specific functions in addition to regulation of fatty acids. This review focuses on the three fatty acid-binding proteins found in the gastrointestinal tract and discusses their role as diagnostic or disease monitoring markers in neonatal necrotizing enterocolitis, acute mesenteric ischemia, celiac disease, and inflammatory bowel disease. Of these three fatty acid-binding proteins, intestinal fatty acid-binding protein is of the most interest due to its exclusive expression in the gastrointestinal tract. The elevation of intestinal fatty acid-binding protein in blood and urine reflects enterocyte damage, regardless of the underlying cause. The short half-life of intestinal fatty acid-binding protein also means it is a relatively sensitive marker. In contrast, there is currently less evidence to support liver fatty acid-binding protein and ileal bile acid-binding protein as sensitive biomarkers in these conditions. More extensive studies with specific endpoints are required to validate the roles of these fatty acid-binding proteins in gastrointestinal diseases.

Nutrition Assessment, Interventions, and Monitoring for Patients with Celiac Disease: An Evidence Analysis Center Scoping Review. J Acad Nutr Diet 2020; 120:1381-1406.

Abstract
The objectives of this scoping review were to identify and characterize studies examining nutrition assessment, interventions, and measures to monitor gluten-free diet (GFD) adherence/compliance in patients with celiac disease (CD). An electronic literature search of four databases (Cochrane Database for systematic reviews, CINAHL, Embase, and Ovid MEDLINE) was conducted to identify articles examining nutrition care in CD individuals. Except for narrative review, grey literature, and case study/report, all types of peer-reviewed articles published between January 2007 and August 2018 were eligible. There were a total of 10,823 records; 10,368 were excluded during the first round of screening due to irrelevancy and/or duplication. Of the 455 full-text articles that were assessed, 292 met the criteria and were included. Most of the studies were observational studies (n=212), followed by experimental trials (n=50), evidence-based practice guideline (EBPG)/report/statement (n=16), and systematic review (SR) (n=14). Nine original studies examined assessment, focusing mainly on different tools/ways to assess GFD adherence. The majority of the included original articles (n=235) were in the nutrition intervention category with GFD, oats, and prebiotics/probiotics as the top-three most studied interventions. There were eight SRs on GFD and five on oats. One SR and 21 original studies investigated the effectiveness of different measures to monitor GFD adherence/compliance. Although recent CD EBPGs were identified, different methods with varying levels of rigor, in terms of literature search and assessment of evidence strength, were used. Based on this scoping review, interventions focused on gluten-free diet and oats have been significantly covered by either SRs or EBPGs. Studies related to prebiotics/probiotics and education program/counseling focused interventions, as well as assessment, in CD patients have increased in recent years. Thus, it might be beneficial to conduct SRs/EBPGs focused on these topics to guide practitioners.

The Use of Biopsy and "No-Biopsy" Approach for Diagnosing Paediatric Coeliac Disease in the Central European Region. Gastroenterol Res Pract 2019; 2019:9370397.

Abstract
Objectives The current European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) guidelines introduced the option to diagnose coeliac disease (CD) in children and adolescents without upper endoscopy if the defined criteria are met. The aim of our study was to evaluate how frequently paediatric gastroenterologists in Central Europe used the “no-biopsy” approach and how often the duodenal biopsy could have been omitted. Methods Medical records of patients aged < 19 years diagnosed with CD in 2016 from five European countries were analysed, focusing on levels of transglutaminase antibodies (TGA) at the time of diagnosis and on whether the diagnosis was confirmed using duodenal biopsy or “no-biopsy” approach. Clinical presentation and delays until final diagnosis were analysed according to diagnostic approach. Results Data from 653 children (63.9% female, median age: 7 years, range: 7 months-18.5 years) from Croatia, Hungary, Germany, Italy, and Slovenia were analysed. One fifth (n = 134) of included children were asymptomatic at diagnosis. Of 519 symptomatic children, 107 (20.6%) were diagnosed by the “no-biopsy” approach. Out of the remaining 412 children who underwent duodenal biopsies, 214 (51.9%) had TGA ≥ 10 times upper level of normal (ULN) and would have been eligible for the “no-biopsy” approach. Signs and symptoms of malabsorption were more frequent in children diagnosed without duodenal biopsies. There were no differences in diagnostic delays with respect to the diagnostic approach. Conclusion In this cohort, about 60% of symptomatic CD patients could have been diagnosed without duodenal biopsies. The aim of the “no-biopsy” approach was to make the diagnostic procedure less challenging without compromising its reliability. However, this option was applied only in 20%, in spite of fewer burdens to the family and reduced costs. The reasons for this discrepancy are unknown. Physicians should be made more aware about the reliability of CD diagnosis without biopsies when the ESPGHAN guidelines for CD diagnosis are followed.

Abstract
PROBLEM Which is the prevalence and seroprevalence of celiac disease (CD) in women with recurrent reproductive failure? METHOD OF STUDY Retrospective study performed in a single infertility clinic from September 2016 to December 2017. A total of 690 women with unexplained history of recurrent miscarriage and/or recurrent implantation failure were consecutively recruited. IgA anti-transglutaminase 2 (TG2) antibody data were collected, as well as IgG anti-TG2 and IgA/IgG anti-deamidated gluten peptide (DGP) data in most cases, and IgG anti-gliadin antibodies occasionally. In selected women, HLA-DQ genotyping was requested. Biopsy was suggested to all women with positive serological results or belonging to CD risk groups. Reproductive outcomes were recorded from women with high suspicion of CD and a control group comprised of 49 women. RESULTS Anti-TG2-positive women comprised 1% of the sample. An additional 4% was observed considering less-specific antibodies (31 women). Only 39% of sero-positive women accepted duodenal biopsy. HLA and biopsy data discarded CD in 14 sero-positive cases (37%), only one with anti-TG2 antibodies. CD was suggested in 10 sero-positive and three sero-negative women (1.9%). Compared with controls, the live birthrate of the studied women with probable CD was significantly decreased before gluten removal of the diet (P = .015), but significantly increased after that (P = .020). CONCLUSION One percent CD prevalence should be expected after anti-TG2 serological screening. However, more sensitive approaches should be explored, especially considering the potential beneficial effect of the gluten-free diet on the reproductive outcomes of women with CD.

Abstract
Children with celiac disease (CD) are susceptible to reduced bone mineral density (BMD). Our target is to assess the severity of vitamin D deficiency in CD children on a gluten-free diet (GFD), and to evaluate the effectiveness of adding an innovative GF meal, on the clinical and bone biochemical indices of CD patients. 50 CD children who were diagnosed and followed up at Pediatric gastroenterology clinic, Specialized pediatric hospital, Cairo University; by serology and biopsy of the duodenum were included in this prospective study. CD children were on GFD for at least one year. As a control group, 40 healthy children were enrolled. Thorough clinical examination, anthropometric assessment, a complete history and 24 hours dietary recall were done for all the participants in this work. We introduced our innovative GF meal to CD patients twice/day, for 3 consecutive months. Venous blood samples were withdrawn from patients at the study beginning and after 3 months for detection of serum vitamin D, calcium, phosphorous and alkaline phosphatase levels. The anthropometric measurements, serum vitamin D, and calcium were markedly decreased in CD children than that of controls. In CD patients, a significant increase in anthropometric parameters, vitamin D and calcium were found. While there was a significant decline of serum alkaline phosphatase, and a slight decrease in serum phosphorus at the study end. The innovative gluten-free prepared meal confirmed to be of high nutritional value in the management of vitamin D deficiency and improvement of bone indices in CD patient.

Abstract
AIM In 2012, revised criteria for diagnosing childhood coeliac disease were published by the European Society for Paediatric Gastroenterology, Hepatology and Nutrition and incorporated into the revised Swedish guidelines the same year. These made it possible, in certain cases, to diagnose coeliac disease without taking small bowel biopsies. This survey assessed the extent to which the new guidelines were implemented by Swedish paediatric clinics two years after their introduction. METHODS In October 2014, we distributed a paper questionnaire including five questions on diagnostic routines to the 40 paediatric clinics in university or regional hospitals in Sweden that perform small bowel biopsies. RESULTS All 36 (90%) clinics that responded used anti-tissue transglutaminase antibodies as the initial diagnostic test and some also used serological markers. Most clinics (81%) used endoscopy and took multiple duodenal biopsies, whereas only a few (19%) occasionally employed a suction capsule. Almost all clinics (86%) omitted taking small bowel biopsies in symptomatic children with repeatedly high coeliac serology and positive genotyping, thereby avoiding the need for invasive endoscopy under anaesthesia. CONCLUSION The 2012 Swedish Paediatric Coeliac Disease Diagnostic Guidelines had been widely accepted and implemented in routine health care two years after their introduction.

Abstract
To ascertain the knowledge, awareness, and practices pertaining to celiac disease (CD) among the Indian pediatricians. A survey link containing a questionnaire was shared through electronic mail using a pediatric database. The survey was kept active for 6 months; all responses received at the end of the survey were analyzed. Two hundred and seventy one pediatricians out of more than 10,000 chose to respond to the survey. Most pediatricians agreed that more patients with CD are being diagnosed than earlier. The reasons for higher detection of CD were perceived to be higher index of clinical suspicion by pediatricians (86.7%) followed by increased awareness among parents (45.8%). Most pediatricians opined that clinical manifestations which prompted to a diagnosis of CD were failure to thrive (96.2%) and chronic diarrhea (81.4%). Knowledge about atypical manifestations of celiac disease was low. Though knowledge about the common association of CD with type 1 diabetes (62.1%) and autoimmune hepatitis (55.8%) was there, awareness about its association with other uncommon conditions was lacking. Though 68% of the pediatricians were of the opinion that the confirmation of diagnosis by a mucosal biopsy is necessary, 26.5% of respondents believed that only a positive serology was sufficient for a diagnosis. A trial of gluten-free diet (GFD) was thought to be a logical step if serology was positive by 31.3% of respondents. While 87.7% of pediatricians advocated lifelong adherence to GFD, 12.3% felt that GFD could be discontinued in the future. This web-based survey revealed that though pediatricians are seeing increasing number of celiac disease patients, there is a need to increase awareness regarding the disease, its associated conditions, the need for mucosal biopsy to confirm the diagnosis and the necessity of lifelong adherence to GFD.

Abstract
BACKGROUND Celiac disease (CD) is a lifelong condition with significant morbidity and requires an accurate diagnosis. Guidelines for pediatric CD were revised by the European and British Societies of Paediatric Gastroenterology Hepatology and Nutrition in 2012 and 2013, respectively. New recommendations introduced non-biopsy pathway (NBP) of diagnosis for a selective group of symptomatic children whose anti-tissue transglutaminase (anti-tTG) antibody titer is greater than ten times upper limit of normal. A clear understanding of the guidelines amongst consultant pediatricians will ensure all children with suspected CD receive a prompt and secure diagnosis. The aim of this study was to establish the interpretation and implementation of the revised guideline for CD amongst consultant general pediatricians in Southwest England (SWE) during the study period. METHODS Telephone/email survey was conducted amongst consultant general pediatricians (n ≈ 140) working in 12 secondary care hospitals across SWE. The survey included eight questions incorporating three main themes: understanding of diagnostic pathway particularly for non-biopsy diagnosis, awareness of laboratory tests involved, and variations in practice in relation to the revised guidelines. RESULTS Responses were available from 101/140 (72%). One hundred respondents were aware of the revised guidelines for diagnosing CD. However, only 17 respondents stated all the criteria of the guideline required for diagnosis by NBP, with further 17 seeking immediate advice from a specialist. Forty-four listed both the criteria for HLA-DQ2/DQ8 testing applicable to pediatricians. Forty-nine out of 100 pediatricians would commence gluten-free diet only after all the results were available. Thirty-three pediatricians also considered asymptomatic children with high anti-tTG titer eligible for diagnosis of CD by NBP. CONCLUSIONS There is a need for improved understanding of revised CD guidelines amongst consultant general pediatricians especially while using the NBP and requesting HLA-DQ2/DQ8 testing.

Prevalence of celiac disease in a large cohort of young patients with type 1 diabetes. Pediatr Diabetes 2019; 20:414-420. [PMID: 30737863 DOI: 10.1111/pedi.12827] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2018] [Revised: 12/01/2018] [Accepted: 01/27/2019] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Serological screening for celiac disease (CD) allows the identification of individuals genetically predisposed, as type 1 diabetes mellitus (T1DM). However, the diagnosis is confirmed by intestinal biopsy. The aim was to determine the prevalence of immunoglobulin-A anti-tissue transglutaminase antibodies (IgA-tTG) and CD in a large cohort of young T1DM patients. METHODS Screening for CD was randomly conducted in 881 T1DM by IgA-tTG and total IgA. Individuals with positive antibodies were referred to endoscopy/duodenal biopsy. RESULTS The age of the cohort at the screening was 14.3 ± 5.9 years and at T1DM onset was 7.9 ± 4.4 years. The prevalence of positive serology was 7.7%. Median IgA-tTG levels were 117.7 U/mL (interquartile range [IQR] 35.7-131.5 U/mL). Of the 62 duodenal biopsy, CD was diagnosed in 79.0%, yielding an overall prevalence of 5.6%. The mean age of CD patients was 15.6 ± 6.5 years and, at T1DM onset was 6.3 years (4.0-9.9 years). The modified Marsh-Oberhuber histological classification was 22.5% (3a), 36.7% (3b), and 40.8% (3c). In the biopsy-proven patients, T1DM onset occurred at slightly younger ages (6.3 vs 9.7 years, P = 0.1947), gastrointestinal (GI) manifestations, predominantly abdominal pain and distension, were more prevalent (71.4% vs 38.5%, P = 0.027) and higher IgA-tTG titers (128.0 vs 26.3 U/mL, P = 0.0003) were found than in those with negative-biopsies. CONCLUSION Our results demonstrate the prevalence of 7.7% of IgA-tTG and 5.6% of CD in T1DM patients in South Brazil and, emphasize the importance of the screening in high-risk individuals. Furthermore, the presence of GI manifestations and higher IgA-tTG titers strongly suggest the diagnosis of CD.

Abstract
Background Before diagnosis, people with coeliac disease suffer reduced quality of life, which improves substantially after the disease has been diagnosed. Delayed diagnosis is common. The aim of this study was to assess changes over time in prevalence of coeliac disease symptoms/associated medical conditions, time to diagnosis, quality of life and its determinants before and after diagnosis in the United Kingdom. Methods A postal questionnaire was designed in 2015 and sent to 4000 individuals with diagnosed coeliac disease, requesting information on respondents’ socio-demographic and clinical characteristics, and their quality of life pre- and post-diagnosis using the EQ-5D instrument. Data were analysed and compared with results from a survey conducted in 2006 using descriptive analyses, univariate and multivariable regression methods. Results The survey response rate was 40%. Sixty-five percent of respondents reported at least 4 symptoms pre-diagnosis, a significant reduction by 13 percentage points (95% CI: -16.9, − 9.4; p-value: < 0.001) compared to 2006. Pre-diagnosis mean duration of symptoms was 12.8 years (SD: 15.3), a non-significant reduction of 0.6 years (95% CI: -2, 0.8; p-value: 0.426) compared to 2006. There was a significant improvement of 0.20 (95% CI: 0.18, 0.22; p-value: < 0.001) in quality of life from pre- (0.65) to post-diagnosis (0.85). Pre-diagnosis values were significantly higher by 0.09 (95% CI: 0.06, 0.12; p-value: < 0.001) than in 2006. Number of symptoms and low income were associated with decreased quality of life. Conclusions Undiagnosed coeliac disease is associated with a substantial decrement in quality of life. Time to diagnosis has not significantly shortened over the decade 2006–2015, but symptoms are less severe when diagnosis occurs. Harmonising clinical guidelines for intensified active case finding will help improve quality of life of people with coeliac disease.

Abstract
OBJECTIVE Medical nutrition therapy (MNT), by lifelong compliance with a gluten-free diet, is likely the only treatment for celiac disease (CD). Clinical practice guidelines (CPGs) regarding the management of CD emphasize the role of MNT over other treatment options. The aim of the present study was to review and critically appraise CD-specific MNT CPGs and identify areas in need of improvement for better adherence and outcomes. METHODS A comprehensive search was performed using PubMed, Guidelines International Network (GIN), Google Scholar, gray literature, and websites of CD scientific organizations for CPGs, consensus and practice papers on the dietary management of CD, published in the English language. RESULTS A total of 12 CPGs were retrieved and critically appraised by three independent reviewers using the Appraisal of Guidelines Research & Evaluation (AGREE) II instrument. All CPGs were of low quality based on AGREE II. Among the 12 CPGs, the National Institute for Health and Care Excellence guidelines achieved the highest score and were unanimously recommended without modifications by the three reviewers, whereas the American Gastroenterology Association, Alberta Health Services, British Society of Paediatric Gastroenterology, Hepatology and Nutrition, Clinical Resource Efficiency Support Team, and Federation of International Societies of Pediatric Gastroenterology, Hepatology and Nutrition guidelines received the lowest scores. CONCLUSIONS The present study reveals the low quality of guidelines regarding the MNT of CD patients, indicating the need for updated and improved guidelines taking into consideration the proposed items of AGREE II.

Abstract
OBJECTIVE The aim of the present study was to investigate the frequency of celiac disease (CD) in patients with juvenile systemic lupus erythematosus (JSLE) and the potential association of JSLE and CD. METHODS This was a cross-sectional study performed from October 2015 to October 2017. A total of 50 patients with JSLE were included in the study. The levels of total IgA and tissue transglutaminase (tTG) IgA antibody were measured in all patients. Subjects with increased tTG were further evaluated for anti-endomysial antibodies (EMAs). Gastroduodenoscopy and intestinal biopsy were performed in those with increased EMA levels to confirm the diagnosis of CD. RESULTS The study included 44 (88.0%) female and 6 (12.0%) male patients. Of the 50 patients, 30 (60.0%) received corticosteroids, and only 4 (8.0%) received no therapy at the time of the study. Only 3 (6.0%) patients were positive for tTG IgA. Patients with positive tTG IgA were then tested for EMA IgA antibodies, and none of them had a positive result. CONCLUSION We did not find CD in children with systemic lupus erythematosus. Studies with more patients with JSLE are needed to conclude a more precise result.

Abstract
Coeliac disease (CD) is an immune-mediated systemic disorder caused by the ingestion of gluten. In children, it may present with intestinal or extra-intestinal manifestations such as diarrhoea, weight loss, iron deficiency anaemia or faltering growth. Diagnosis is confirmed by small bowel biopsies showing histological changes consistent with enteropathy. In 2012, the European Society for Paediatric Gastroenterology, Hepatology and Nutrition revised the CD guidelines and suggested that, in a selective group of symptomatic children, CD can be diagnosed without the need for small-bowel biopsies. Management of CD is through strict adherence to a life-long gluten-free diet (GFD). CD is of great public health significance as its prevalence in developing countries has been found to be similar to that in developed countries. Early recognition and treatment improves prognosis. Patients and families require long term support to enable effective adherence to a GFD lifestyle. This alone can be challenging, but through support of health professionals and dietitians, can improve patient outcomes. In resource-limited settings medical professionals need to be creative in formulating cheaper and locally sourced gluten free options in close cooperation with the dietitians thereby ensuring availability of gluten free food items at affordable prices. In this paper, we gave an overview of the subject followed by authors' view to emphasize the need for improved awareness in resource-limited settings.

Abstract
AIM Elevated levels of anti-tissue transglutaminase (anti-tTG) antibody may spontaneously normalise in children with newly diagnosed type 1 diabetes, even if they eat gluten. The prevalence of this phenomenon and predictors of a subsequent coeliac disease (CD) diagnosis were determined. METHODS The medical records of children diagnosed with type 1 diabetes at Ha'Emek Medical Centre, Israel, from 2007 to 2015, were retrospectively reviewed for elevated anti-tTG antibody levels. Demographic, clinical, laboratory and histological findings were compared between CD patients and those with transient coeliac serology. RESULTS Of 425 patients with new onset type 1 diabetes, 34 (8%) had elevated anti-tTG antibodies: CD was diagnosed in 14, anti-tTG normalisation occurred in 13 and duodenal biopsies did not suggest CD in seven without anti-tTG antibody normalisation. Protective factors for a subsequent CD diagnosis were older age (p = 0.009) and mildly elevated anti-tTG antibody levels at the time of the type 1 diabetes diagnosis (p = 0.007), and decreased anti-tTG levels within six months of diagnosis (p = 0.03). CONCLUSION Serological follow-up of a diet containing gluten is recommended for children who have newly diagnosed type 1 diabetes and slightly elevated anti-tTG antibodies with no symptoms that suggest CD.

Abstract
AIM Coeliac disease is a common but markedly under-diagnosed condition, which may lead to serious long-term complications if untreated. Both the diagnostic yield and true incidence have significantly increased during the last few decades and it is now one of the most common chronic gastrointestinal conditions in children. The aim of this review was to summarise the current concepts on screening for coeliac disease in children and adolescents. METHOD We conducted a non-systematic literature review of papers published about coeliac disease screening since the year 2000. RESULTS Our review showed that the diagnostic yield could be significantly improved by screening for at-risk groups, or even the whole population, but these approaches remain controversial. Evidence suggests that screening for certain high-risk groups could be beneficial, but untargeted mass screening is not currently recommended. However, whether the benefits of an early diagnosis would overcome the challenges of lifelong dietary treatment, especially in asymptomatic individuals who consider themselves healthy, are unclear. CONCLUSION There is moderate evidence that screening certain at-risk groups for coeliac disease could be beneficial, but more studies in different settings are needed before large-scale population screening can be recommended.

Abstract
Small bowel capsule endoscopy (SBCE) can identify macroscopic changes of coeliac disease and assess the extent of disease in the small bowel beyond the duodenum. SBCE has a good sensitivity for the detection of coeliac disease in comparison to histology owing to several ideal features such as a high magnification. It also plays a useful role in detecting complications in patients with refractory coeliac disease. Several studies have been carried out on transforming images obtained from small bowel capsule endoscopy to enable the automated detection of features related to coeliac disease. This review discusses the current roles played by small bowel capsule endoscopy in coeliac disease. It identifies future potential roles of this technique and describes in great detail the role of computational analysis in the detection of coeliac disease and how it can be adapted to current available technology.
