J Transl Med 2024; 104:102028. [PMID: 38382808 DOI: 10.1016/j.labinv.2024.102028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 01/26/2024] [Accepted: 02/13/2024] [Indexed: 02/23/2024] Open
Abstract
Primary gastrointestinal (GI) T-cell and natural killer (NK)-cell lymphomas/lymphoproliferative disorders (LPD) are uncommon, and they are usually aggressive in nature. However, T-cell and NK-cell lymphoma/LPD of the GI tract with indolent clinical course has been reported over the past 2 decades. Indolent T-cell LPD was formally proposed a decade ago in 2013 and 4 years later recognized as a provisional entity by the revised fourth edition of WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues in 2017. Indolent T-cell LPD of the GI tract has been changed to indolent T-cell lymphoma of the GI tract as a distinct entity by the fifth edition of WHO Classification of Haematolymphoid Tumours, but the International Consensus Classification of mature lymphoid neoplasms prefers indolent clonal T-cell LPD of the GI tract instead. In the past decade, indolent lymphoma/LPD of the GI tract has been expanded to NK cells, and as such, indolent NK-cell LPD of the GI tract was recognized as an entity by both the fifth edition of WHO Classification of Haematolymphoid Tumours and the International Consensus Classification. The underlying genetic/molecular mechanisms of both indolent T-cell lymphoma/LPD of the GI tract and indolent NK-cell LPD of the GI tract have been recently discovered. In this review, we describe the history; salient clinical, cytohistomorphologic, and immunohistochemical features; and genetic/genomic landscape of both entities. In addition, we also summarize the mimics and differential diagnosis. Finally, we propose future directions with regard to the pathogenesis and clinical management.

Abstract
Barley (Hordeum vulgare L.) is a major cereal crop produced globally. Hordeins, the major storage proteins in barley, can trigger immune responses leading to celiac disease or symptoms associated with food allergy. Here, proteomics approaches were employed to investigate the proteome level changes of grain and malt from the malting barley cultivar, Sloop, and single-, double- and triple hordein-reduced lines. The triple hordein-reduced line is an ultra-low gluten barley cultivar, Kebari®. Using discovery proteomics, 2,688 and 3,034 proteins in the barley and malt samples were detected respectively. Through the application of targeted proteomics, a significant reduction in the quantity of B-, D-, and γ-hordeins, as well as avenin-like proteins, was observed in the ultra-low gluten malt sample. A compensation mechanism was observed evidenced by increased biosynthesis of seed storage globulins, specifically vicilin-like globulins. Overall, this study has provided insights into protein compositional changes after malting in celiac-friendly barley varieties.

[PMID: 37038158 PMCID: PMC10088139 DOI: 10.1186/s12887-023-03982-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Accepted: 03/31/2023] [Indexed: 04/12/2023] Open
Abstract
BACKGROUND This case report describes a cystic fibrosis case after 7 years of a presumed diagnosis of celiac disease without confirming laboratory tests and biopsies. Both cystic fibrosis and celiac disease cause malnutrition, malabsorption, and failure to thrive. Also, the occurrence of cystic fibrosis in celiac disease patients is higher than in the normal population. Therefore, the differentiation between the two diseases might be challenging. This article highlights the reason for the confusion between cystic fibrosis and celiac disease and emphasizes the importance of not skipping the necessary investigations no matter how difficult it is to perform them. CASE PRESENTATION This report details the case history of a patient presumed to have celiac disease for 7 years without confirming investigations. He developed multiple respiratory infections and weight loss throughout the 7 years but was only diagnosed with cystic fibrosis after hospitalization for gradual abdominal distension and productive cough. Chest CT showed atelectasis in the right upper lobe, tree-in-bud sign on both sides, and right periumbilical mass with several enlargements in the mediastinal nodes. Ascites paracentesis revealed a high SAAG gradient and low-protein fluid. The sweat chloride test resulted in a chloride level of 90 mEq/L, which confirmed the cystic fibrosis diagnosis. Subsequent genetic testing revealed the rare G85E mutation. CONCLUSION This report highlights the potential for diagnostic confusion between cystic fibrosis and celiac disease. Also, it reminds physicians about the importance of taking a detailed medical history and performing the essential investigations no matter how difficult it is to do them. Finally, it emphasizes the need to verify the patient's previous medical history in case there is no official documentation of his case. This should be considered particularly in rural areas in low-income countries where the possibility of medical malpractice should not be forgotten.

Abstract
AIMS This study aimed to explore dietitians' perspectives on the evidence surrounding the relationship between diet and 'gut health' and the current and emerging role of dietetics practice in this area. METHODS A qualitative descriptive methodology was used. Online semi-structured interviews were conducted with Australian dietitians, focused on the perspectives related to gut health management in dietetics practice. Inductive thematic analysis was employed, commencing with initial coding by two researchers, and further coding leading to development of emergent themes. Divergent data were discussed and considered in analysis. RESULTS Fourteen interviews were conducted (2 males, 12 females). An overarching theme identified that current evidence is insufficient to direct dietetics practice change regarding gut health. Six subthemes on dietetics practice in 'gut health' emerged including (a) practice is multifaceted, (b) current practice aligns with dietary guidelines, (c) symptom management remains the primary concern, (d) evidence-based information is sought, (e) translational evidence is required for practice change and (f) there is a role for dietetics in gut health research and translation. CONCLUSIONS Dietitians do not appear confident in their practice regarding gut microbiome-related management and recognise there is currently limited translatable research to inform practice. Evidence to date suggests that recommendations for positive gut health do not differ substantially from Australian Dietary Guidelines. Dietitians will need additional education if further evidence emerges, however they demonstrated a strong commitment to evidence-based practice.

Abstract
Celiac disease (CD) is a multiorgan autoimmune disorder of the chronic intestinal disease group characterized by duodenal inflammation in genetically predisposed individuals, precipitated by gluten ingestion. The pathogenesis of celiac disease is now widely studied, overcoming the limits of the purely autoimmune concept and explaining its hereditability. The genomic profiling of this condition has led to the discovery of numerous genes involved in interleukin signaling and immune-related pathways. The spectrum of disease manifestations is not limited to the gastrointestinal tract, and a significant number of studies have considered the possible association between CD and neoplasms. Patients with CD are found to be at increased risk of developing malignancies, with a particular predisposition of certain types of intestinal cancer, lymphomas, and oropharyngeal cancers. This can be partially explained by common cancer hallmarks present in these patients. The study of gut microbiota, microRNAs, and DNA methylation is evolving to find the any possible missing links between CD and cancer incidence in these patients. However, the literature is extremely mixed and, therefore, our understanding of the biological interplay between CD and cancer remains limited, with significant implications in terms of clinical management and screening protocols. In this review article, we seek to provide a comprehensive overview of the genomics, epigenomics, and transcriptomics data on CD and its relation to the most frequent types of neoplasms that may occur in these patients.

Abstract
Celiac disease (CD) is a chronic autoimmune condition with intestinal and extra-intestinal features. Extra intestinal features including hematological, neurological, and endocrine symptoms are seen more frequently in elder children. A 4 years 7 months old male child presented in clinic with history of abdominal pain and diarrhea on and off for 1 year. On examination, he was hemodynamically stable, pale, and malnourished with distended abdomen. He was investigated for CD, Anti TTG IgA <0.1 (positive >10), Anti TTG IgG 13 (positive >10). To confirm celiac disease, Esophagogastroduodenoscopy (EGD) was done which was consistent with diagnosis of Celiac disease (MARSH Type 3a). Gluten free diet was advised. Later, after 12 days he again presented with jaundice, fever, anorexia, and dark colored urine and irritability. He was admitted for fulminant hepatic failure, his workup revealed direct hyperbilirubenemia, ANA +ve, and hyper IgG. Liver biopsy confirmed autoimmune hepatitis. Further workup for anemia showed reticulocyte count 7.1, LDH 423, direct and indirect coombs test was positive confirming autoimmune hemolytic anemia. Child responded well to Azathioprine and prednisolone with clinical improvement. We report a rare presentation of celiac disease with polyautoimmunity in a young child. Case reports of autoimmune hepatitis with CD patients have been reported in adult patients. Association of celiac disease with autoimmune hemolytic anemia and autoimmune hepatitis is a distinct and rare condition.

Gluten-free diet adherence and implications for the diagnosis of coeliac disease. Pathology 2022; 54:606-610.

Abstract
Coeliac disease (CD) is an autoimmune disorder caused by the ingestion of gluten containing foods in genetically susceptible individuals, with a worldwide prevalence of up to 1%. Currently, the only available treatment is a gluten-free diet (GFD). Screening for CD is primarily performed using serum based testing for anti-tissue transglutaminase (tTG) antibodies. Patients must be on a gluten containing diet at the time of testing to ensure an accurate serological result. We investigated the prevalence of a GFD in hospital clinic settings and the general population using survey data to estimate the proportion of CD patients that may be misdiagnosed for CD based on serological tests. Data were collected at clinics of a metropolitan hospital in Sydney, Australia, and the general population. Data from Medicare Benefits Scheme and tTG results from a large Australian private laboratory were reviewed for comparison. Of 778 participants who responded to the survey, 58 (7.5%) were on a GFD. More patients attending the immunology (15.9%) and gastroenterology (12.1%) clinics adopted a GFD than those attending the diabetes (2.6%) or endocrinology (6.1%) clinics, or in the general population (4.3%). More females than males excluded gluten from their diet (p<0.0001). Medicare statistics between 2013 and 2019 demonstrated an increase in CD serological testing; however, tTG data from a private pathology highlighted a stable level of elevated tTG antibodies of 3% of total tests performed. The high number of individuals on a GFD is likely impacting the ability to accurately diagnose CD using serum-based testing.

Abstract
Numerous disorders can alter the physiological mechanisms that guarantee proper digestion and absorption of nutrients (macro- and micronutrients), leading to a wide variety of symptoms and nutritional consequences. Malabsorption can be caused by many diseases of the small intestine, as well as by diseases of the pancreas, liver, biliary tract, and stomach. This article provides an overview of pathophysiologic mechanisms that lead to symptoms or complications of maldigestion (defined as the defective intraluminal hydrolysis of nutrients) or malabsorption (defined as defective mucosal absorption), as well as its clinical consequences, including both gastrointestinal symptoms and extraintestinal manifestations and/or laboratory abnormalities. The normal uptake of nutrients, vitamins, and minerals by the gastrointestinal tract (GI) requires several steps, each of which can be compromised in disease. This article will first describe the mechanisms that lead to poor assimilation of nutrients, and secondly discuss the symptoms and nutritional consequences of each specific disorder. The clinician must be aware that many malabsorptive disorders are manifested by subtle disorders, even without gastrointestinal symptoms (for example, anemia, osteoporosis, or infertility in celiac disease), so the index of suspicion must be high to recognize the underlying diseases in time.

Abstract
OBJECTIVES Celiac disease (CD) remains undiagnosed for a long time in many adult and pediatric patients. We assessed the knowledge about CD among healthcare professionals (HCPs) and CD patients in Central Europe (CE). METHODS HCPs and CD patients from 5 CE countries were asked to complete the web-based questionnaire about CD. The questions were divided into subsections on epidemiology, clinical presentation, diagnostics, treatment, and follow-up. Achieved scores of different specialists managing patients with CD were compared and regional differences in patients' knowledge were analyzed. RESULTS Questionnaire was completed by 1381 HCPs and 2262 CD patients or their caregivers from Croatia, Hungary, Germany, Italy, and Slovenia. Mean score achieved by HCPs was 50.9%, and by CD patients 56.4%. Pediatric gastroenterologists scored the highest (69.4%; P < 0.001). There were significant differences in knowledge of patients from different CE regions with German participants scoring the highest (58.3%). Members of CD societies scored higher compared with nonmembers (mean score 58% vs 53.2%; P < 0.001) and patients diagnosed less than 5 years ago scored higher compared with those diagnosed more than 10 years ago (mean score 57.3% vs 54.6%; P < 0.001). CONCLUSIONS The knowledge about CD among HCPs and CD patients is not satisfactory. Further awareness-raising and learning activities are needed to improve HCPs' knowledge and to minimize the number of unrecognized patients and unnecessary diagnostic delays. Patients should be better informed about their disease to reach higher compliance with the gluten-free diet.

Abstract
Gluten is a common dietary component with a complex protein structure. It forms incomplete products of digestion, which have the potential to mount an immune response in genetically predisposed individuals, resulting in celiac disease. It also has been linked with nonceliac gluten sensitivity and irritable bowel syndrome due to wheat allergy. A gluten-free diet is an effective treatment of these conditions; however, it can lead to micronutrient and mineral deficiencies and a macronutrient imbalance with higher sugar and lipid intake. Recent popularity has led to greater availability, but increasing cost, of commercially available gluten-free products.

Abstract
The prevalence of coeliac disease in the general population is 0.5–1%; however, most patients remain undiagnosed until adult age. In some cases, the onset is represented by sub-clinical signs, some of which can be found in the mouth. The aim of this research was to identify any associations between the clinical characteristics of coeliac disease and oral manifestations. A structured questionnaire was administered to a group of 237 individuals with coeliac disease. 100% of the subjects fully completed the questionnaire. Among them, 182 (76.7%) were female, 64 patients (27%) were aged 15 to 24 years, 159 (67%) were aged 25 to 55 and 14 (6%) were aged 56 and over. Significant associations were observed in caries prevalence and dentin sensitivity; in addition, an inappropriate diet was related to oral manifestations; following a gluten-free diet could be important to control the gingival bleeding levels and to manage oral symptoms associated to coeliac disease. In general, the presence of inflammatory symptoms in the mouth seems to be associated with general symptoms of inflammation related to coeliac disease.

Abstract
The purpose of this study is to understand the health-related quality of life (HRQoL) in patients with celiac disease (CD) and analyze its main determinants. A transversal descriptive study of 738 patients with celiac disease was carried out. A series of questionnaires were answered related to their HRQoL, adherence to a gluten-free diet (GFD), and self-efficacy beliefs among other relevant variables. Regression analyses were carried out in order to explore the predictive variables in adherence to the GFD and HRQoL. A total of 61.2% showed a good HRQoL, and the main predictors of HRQoL were specific self-efficacy, adherence to the diet, risk perception, time since diagnosis, and age. While 68.7% of participants showed good or excellent adherence to the GFD, and the main predictors of adherence were specific self-efficacy, perceived adoption of recommended behaviors, HRQoL and gender. The HRQoL of patients with CD, and adherence to the GFD in Spain, are good. It is the self-efficacy expectation, measured specifically and not generally, which is the best predictor of both adherence and HRQoL. It is necessary to develop programs to improve the HRQoL of patients with CD that focus on improving specific self-efficacy.

Abstract
In coeliac disease, the diagnostic work-up is based on a combination of clinical, histopathological and serological evaluation. Among the serological tests, the presence of tissue transglutaminase (tTG) IgA antibodies is the cornerstone owed to a high sensitivity and specificity. Recently, Immunodiagnostic Systems Ltd (IDS) introduced the fully automated chemiluminescent autoimmune assays for use on the IDS-iSYS Multi-Discipline Automated System. In this study, we aimed to compare the performance of the IDS-iSYS assay to the Thermo Fisher Phadia assay and to establish the upper reference limit of tTG IgA in a healthy population from Denmark based on the IDS-iSYS assay. We discovered a total imprecision of CV = 12.2% (2.87 AU/mL) and CV = 10.6% (47.55 AU/mL). Moreover, we compared the performance of IDS-iSYS assay to Thermo Fisher Phadia assay in 236 samples from unselected patients submit for tTG IgA testing and found a concordance of 97% (p < .0001). Furthermore, in 150 healthy blood donors, we established the upper reference limit of 3.26 AU/mL (95% CI: 3.10 - 3.90) was identified. Our study validates the performance of the IDS-iSYS tTG IgA assay and demonstrates results in concordance with the established Thermo Fisher Phadia. Furthermore, it provides estimates for the upper reference interval limit of the tTG-IgA.

Abstract
AbstractThis article consists of a study of the literature and an assessment of available data on the production of gluten-free beer and its constituents. The article shows how the FAO/WHO Codex Alimentarius Commission for Nutrition and Foods for Special Dietary Uses defines celiac disease, gluten-free products, and gluten-free beer. It describes diet-dependent diseases, which require a gluten-free diet, and groups of potential consumers of gluten-free beer. This article describes the use of oats as a raw material for the production of brewing malt and its usefulness in the production of beer. It specifies how the technological process of standard beer production needs to be modified so that the product meets the requirements of patients with celiac disease. The article also provides an overview of literature data on the production of gluten-free beer from pseudocereal malts, such as sorghum malt, buckwheat malt, amaranth malt, and quinoa malt.

Abstract
Introduction: Duodenal eosinophilia is a key feature of functional dyspepsia, particularly in those with early satiety. Duodenal eosinophilia is also recognised in coeliac disease, although its relevance to symptoms is not understood. We aimed to determine if duodenal eosinophilia is present in patients with coeliac disease presenting with dyspepsia, and whether other histological characteristics were associated with clinical features on presentation.Methods: The coeliac study population comprised 61 patients with a new presentation of coeliac disease to a single centre from 2003 to 2013. A standard symptom assessment was documented for all patients. The control population (55 adults) presenting for endoscopy without coeliac disease was drawn from the same centre with similar demographics for age and gender. Duodenal biopsies from both groups were assessed for eosinophil counts and histological features.Results: Dyspepsia was present in 18.0% of coeliac patients and early satiety in 24.6%. The eosinophil counts were significantly higher in the stomach (12.1/mm2 vs. 4.0/mm2, p < .001) and duodenum (60.4/mm2 vs. 18.0/mm2, p < .001) of coeliac patients compared with controls. There was no significant difference in the mean duodenal eosinophil count in coeliac disease with and without early satiety (55.4/mm2 vs. 66.9/mm2, p = .51). Duodenal eosinophilia was not associated with the severity of coeliac enteropathy. The degree of villous atrophy was associated with iron deficiency at presentation (p = .01), but not symptoms.Conclusions: Although duodenal eosinophil counts are higher in coeliac disease than controls, we were not able to demonstrate an association with presenting symptoms or markers of disease severity.

Abstract
BACKGROUND & AIMS There is debate over the presence and prevalence of brain injury in patients with celiac disease. To validate previous reports, we investigated the prevalence of neuropsychological dysfunction in persons with celiac disease included in the National UK Biobank, which contains experimental medical data from 500,000 adults in the United Kingdom. METHODS Biobank participants with celiac disease (n = 104; mean age, 63 years; 65% female) were matched with healthy individuals (controls, n = 198; mean age, 63 years; 67% female) for age, sex, level of education, body mass index, and diagnosis of hypertension. All participants were otherwise healthy. We compared scores from 5 cognitive tests and multiple choice responses to 6 questions about mental health between groups using the t test and chi-squared analyses. Groupwise analyses of magnetic resonance imaging brain data included a study of diffusion tensor imaging metrics (mean diffusivity, fractional anisotropy, radial diffusivity, axial diffusivity), voxel-based morphometry, and Mann-Whitney U comparisons of Fazekas grades. RESULTS Compared with control individuals, participants with celiac disease had significant deficits in reaction time (P = .004), and significantly higher proportions had indications of anxiety (P = .025), depression (P = .015), thoughts of self-harm (P = .025), and health-related unhappiness (P = .010). Tract-based spatial statistics analysis showed significantly increased axial diffusivity in widespread locations, demonstrating white matter changes in the brains of participants with celiac disease. Voxel-based morphometry and Fazekas grade analyses did not differ significantly between groups. CONCLUSIONS In an analysis of data from the UK Biobank, we found participants with celiac disease to have cognitive deficit, indications of worsened mental health, and white matter changes, based on analyses of brain images. These findings support the concept that celiac disease is associated with neurologic and psychological features.

Abstract
Celiac disease (CD) is an immunological disorder that mainly affects the small intestine, generating an inflammatory process in response to the presence of gluten (a protein). Autoimmune diseases are part of a group of diseases that are difficult to diagnose without a specific protocol or consensus to detect them due to the number of symptoms and diseases with which it has a relationship. Therefore, the aim of this review was to analyze the diagnostic tools of CD used in middle-aged women, to compare the use and effectiveness of the different tools, and to propose a strategy for the use of the tools based on the results found in the literature. The present research followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The search was conducted in the following databases: Scielo, PubMed, Web of Science, and Worldwide Science org. In the initial literature search, 2004 titles and relevant abstracts were found. Among them, 687 were duplicates, leaving 1130 articles. Based on the inclusion criteria, only 41 articles passed the selection process; 4 main types of analyses appear in the studies: blood tests, questionnaires, clinical history, and biopsy. It can be said that none of the analyses have a 100% reliability since most of them can present false negatives; therefore, the best way to diagnose celiac disease up to now is through a combination of different tests (Immunoglobulin A and small intestinal biopsy).

Abstract
OBJECTIVES To determine the incidence of self-reported non-coeliac wheat sensitivity (SR-NCWS) and factors associated with its onset and resolution; to describe the prevalence of factors associated with gluten avoidance. DESIGN Longitudinal cohort study; analysis of responses to self-administered validated questionnaires (Digestive Health and Wellbeing surveys, 2015 and 2018). SETTING, PARTICIPANTS Subset of an adult population sample randomly selected in 2015 from the electoral rolls for the Newcastle and Gosford regions of New South Wales. MAIN OUTCOME MEASURES Prevalence of SR-NCWS (2015, 2018) and incidence and resolution of SR-NCWS, each by demographic and medical factors; prevalence of gluten avoidance and reasons for gluten avoidance (2018). RESULTS 1322 of 2185 eligible participants completed the 2018 survey (response rate, 60.5%). The prevalence of SR-NCWS was similar in 2015 (13.8%; 95% CI, 12.0-15.8%) and 2018 (13.9%; 95% CI, 12.1-15.9%); 69 of 1301 respondents (5.3%) reported developing new onset (incident) SR-NCWS between 2015 and 2018 (incidence, 1.8% per year). Incident SR-NCWS was significantly associated with a diagnosis of functional dyspepsia, and negatively associated with being male or older. Gluten avoidance was reported in 2018 by 24.2% of respondents (20.5% partial, 3.8% complete avoidance); general health was the most frequent reason for avoidance (168 of 316 avoiders, 53%). All 13 participants with coeliac disease, 56 of 138 with irritable bowel syndrome (41%), and 69 of 237 with functional dyspepsia (29%) avoided dietary gluten. CONCLUSIONS The prevalence of SR-NCWS was similar in 2015 and 2018. Baseline (2015) and incident SR-NCWS (2018) were each associated with functional gastrointestinal disorders. The number of people avoiding dietary gluten exceeds that of people with coeliac disease or SR-NCWS, and general health considerations and abdominal symptoms are the most frequently reported reasons for avoidance.

Abstract
Celiac disease (CD) is an immune-mediated gastrointestinal (GI) disorder driven by innate and adaptive immune responses to gluten. Presentation of CD has changed over time, with non-GI symptoms, such as anemia and osteoporosis, presenting more commonly. With improved screening and diagnostic methods, the reported prevalence of CD has increased globally, and there is considerable global variation in diagnostic and treatment practices. The objective of this study was to describe the current state of CD diagnosis and treatment patterns. A targeted review of literature from MEDLINE, Embase, the Cochrane Library, and screening of relevant conference abstracts was performed. The generally recommended diagnostic approach is GI endoscopy with small bowel biopsy; however, in selected patients, biopsy may be avoided and diagnosis based on positive serology and clinical symptoms. Diagnosis often is delayed; the average diagnostic delay after symptom onset is highly variable and can last up to 12 years. Barriers to accurate and timely diagnosis include atypical presentation, lack of physician awareness about current diagnostic criteria, misdiagnosis, and limited access to specialists. Currently, strict adherence to a gluten-free diet (GFD) is the only recommended treatment, which is not successful in all patients. Only one-third of patients are monitored regularly following diagnosis. Unmet needs for CD include improvements in the accuracy and timeliness of diagnosis, and the development of treatments for both refractory CD and GFD nonresponsive CD. Further research should investigate the impact of education about gluten-free eating and the availability of gluten-free foods support adherence and improve outcomes in patients with CD.

Abstract
BACKGROUND Coeliac crisis is a life-threatening presentation of coeliac disease. Severe diarrhoea, weight loss, electrolyte imbalances and malnutrition are prominent features. Although mainly a disease of childhood, it can on the rare occasion be diagnosed in adults. CASE PRESENTATION A 25-year-old female with severe generalised oedema, lower extremity weakness, hypokalemia and profound hypoalbuminemia was referred with an initial diagnosis of nephrotic syndrome. Three months previously she had given birth to a healthy child following an uneventful pregnancy. She did not have proteinuria. She had a history of diarrhoea with gluten-containing food since childhood but lacked a formal diagnosis of coeliac disease. A duodenal biopsy confirmed the suspected diagnosis. Coeliac crisis was diagnosed with life-threatening multisystem involvement. Introduction of a gluten-free diet abolished all disease symptoms and ameliorated laboratory parameters at six months' follow-up. CONCLUSION Coeliac crisis is a rare, yet dangerous presentation of coeliac disease in adults. As this case suggests, it can present with generalised oedema and hypoalbuminemia mimicking nephrotic syndrome. Rapid diagnosis is the key to successful treatment.

Abstract
OBJECTIVES To investigate the frequency of coeliac disease (CD)-specific human leucocyte antigen (HLA) genotypes in paediatric patients with type 1 diabetes (T1D), who are known to have a higher prevalence of CD than the general population, and to evaluate whether HLA genotyping is a suitable first-line screening method for CD. STUDY DESIGN The study was a multicentre observational analysis of patients with T1D aged <20 years of whom a subgroup had undergone HLA genotyping. Patient data were retrieved from the Diabetes Prospective Follow-up database, a large diabetes follow-up registry. The present analysis included data from 439 centres throughout Germany, Austria, Switzerland and Luxembourg. RESULTS In March 2017, the database contained 75 202 patients with T1D (53% male, mean age (SD) 14.6 (4.1) years, mean age at diagnosis 8.8 (4.3) years and mean diabetes duration 5.8 (4.3) years). 1624 patients had undergone coeliac-specific HLA genotyping, of whom 1344 (82.8%) were positive for HLA-DQ2, HLA-DQ8 or both, while 17.2% had no coeliac-specific HLA-markers. 26.6% of at-risk patients had a clinical suspected diagnosis of CD, and 3.6% had biopsy-proven CD. CONCLUSIONS Genotyping for HLA-DQ2, HLA-DQ8 or both is positive in the vast majority (>80%) of patients with T1D. Therefore, screening for coeliac-specific HLA genotypes as a first-line test is not a suitable method to exclude CD in T1D. Regular screening for coeliac-specific antibodies in T1D is still recommended.

Abstract
AIM To analyze the relationships between pre-diagnosis coeliac serology, duodenal histopathology, primary presenting symptoms, coeliac-related comorbidity and response to treatment in a modern cohort with new diagnosis of coeliac disease (CD).
METHODS A retrospective cohort study including 99 participants diagnosed with CD between 1999 and 2013. All patients had the following data recorded: baseline characteristics, coeliac serology, small bowel histopathology. A subset of this cohort underwent a repeat small bowel biopsy. Independent associations were assessed with logistic regression.
RESULTS The mean age at diagnosis was 43 years (Interquartile range 30-53 years) and 68% of the cohort was female. At diagnosis 49 (49%) patients had total villous blunting (MS 3c), 12 (12%) had subtotal villous blunting (MS 3b), and 29 (29%) had partial villous blunting (MS 3a). The prevalence of symptoms pre diagnosis was not related to the severity of villous blunting (P = 0.490). 87 (88%) of the cohort underwent repeat small bowel biopsy after a median of 7 mo (IQR 6-11 mo). 34 (39%) patients had biopsy results ≥ MS 3a which compared to 90 (90%) at the initial biopsy. 24 (71%) of this group reported adherence to a gluten free diet (GFD). Persistent MS ≥ 3a at repeat biopsy was not associated with symptoms (P = 0.358) or persistent positive coeliac serology (P = 0.485).
CONCLUSION Neither symptoms nor serology predict the severity of the small bowel mucosal lesion at CD diagnosis. Whilst a GFD was associated with histological improvement many patients with newly diagnosed CD had persistent mucosal damage despite many months of gluten restriction. Negative CD serology did not exclude ongoing mucosal injury.

A Serological Diagnosis of Coeliac Disease Is Associated with Osteoporosis in Older Australian Adults. Nutrients 2018; 10:nu10070849.

Abstract
Previously thought to be mainly a disorder of childhood and early adult life, coeliac disease (CeD) is increasingly diagnosed in older adults. This may be important given the association between CeD and osteoporosis. The primary aim of this study was to determine the seroprevalence of undiagnosed CeD (‘at-risk serology’) in an older Australian community and relate this to a diagnosis of osteoporosis and fractures during a follow-up period of 12 years. We included participants from the Hunter Community Study (2004–2007) aged 55–85, who had anti-tissue transglutaminase (tTG) titres, human leukocyte antigen (HLA) genotypes, and bone mineral density measurements at baseline. Follow-up data included subsequent diagnosis of CeD and fractures using hospital information. ‘At-risk’ serology was defined as both tTG and HLA positivity. Complete results were obtained from 2122 patients. The prevalence of ‘at-risk’ serology was 5%. At baseline, 3.4% fulfilled criteria for a diagnosis of osteoporosis. During a mean of 9.7 years of follow-up, 7.4% of the cohort suffered at least one fracture and 0.7% were subsequently diagnosed with CeD. At-risk serology was significantly associated with osteoporosis in a multivariate model (odds ratio 2.83, 95% confidence interval 1.29–6.22); there was insufficient power to look at the outcome of fractures. The results of this study demonstrate that at-risk CeD serology was significantly associated with concurrent osteoporosis but not future fractures. Most individuals with a serological diagnosis of CeD were not diagnosed with CeD during the follow-up period according to medical records. Coeliac disease likely remains under-diagnosed.

Abstract
Gluten‐related disorders are a complex group of diseases that involve the activation of the immune system triggered by the ingestion of gluten. Among these, celiac disease, with a prevalence of 1 %, is the most investigated, but recently, a new pathology, named nonceliac gluten sensitivity, was reported with a general prevalence of 7 %. Finally, there other less‐prevalent gluten‐related diseases such as wheat allergy, gluten ataxia, and dermatitis herpetiformis (with an overall prevalence of less than 0.1 %). As mentioned, the common molecular trigger is gluten, a complex mixture of storage proteins present in wheat, barley, and a variety of oats that are not fully degraded by humans. The most‐studied protein related to disease is gliadin, present in wheat, which possesses in its sequence many pathological fragments. Despite a lot of effort to treat these disorders, the only effective method is a long‐life gluten‐free diet. This Review summarizes the actual knowledge of gluten‐related disorders from a translational chemistry point of view. We discuss what is currently known from the literature about the interaction of gluten with the gut and the critical host responses it evokes and, finally, connect them to our current and novel molecular understanding of the supramolecular organization of gliadin and the 33‐mer gliadin peptide fragment under physiological conditions.

Potter MDE, Walker MM, Talley NJ. Non-coeliac gluten or wheat sensitivity: emerging disease or misdiagnosis? Med J Aust 2017; 207:211-215.

Abstract
Non-coeliac gluten or wheat sensitivity (NCG/WS) is a condition characterised by adverse gastrointestinal and/or extra-intestinal symptoms associated with the ingestion of gluten- or wheat-containing foods, in the absence of coeliac disease or wheat allergy. Up to one in 100 people in Australia may have coeliac disease but many more report adverse gastrointestinal and/or extra-intestinal symptoms after eating wheat products. In the absence of validated biomarkers, a diagnosis of NCG/WS can only be made by a double-blind, placebo-controlled, dietary crossover challenge with gluten, which is difficult to apply in clinical practice. Of people self-reporting gluten or wheat sensitivity, only a small proportion (16%) will have reproducible symptoms after a blinded gluten challenge of gluten versus placebo in a crossover dietary trial and fulfil the current consensus criteria for a diagnosis of NCG/WS. A wide range of symptoms are associated with NCG/WS, including gastrointestinal, neurological, psychiatric, rheumatological and dermatological complaints. The pathogenesis of NCG/WS is not well understood, but the innate immune system has been implicated, and there is overlap with coeliac disease and the functional gastrointestinal disorders (irritable bowel syndrome and functional dyspepsia). Identification of NCG/WS is important as gluten-free diets carry risks, are socially restricting and are costlier than regular diets.
