Abstract
Celiac disease is an immune-mediated intestinal disorder that results from loss of oral tolerance (LOT) to dietary gluten. Reovirus elicits inflammatory Th1 cells and suppresses Treg responses to dietary antigen in a strain-dependent manner. Strain type 1 Lang (T1L) breaks oral tolerance, while strain type 3 Dearing reassortant virus (T3D-RV) does not. We discovered that intestinal infection by T1L in mice leads to the recruitment and activation of NK cells in mesenteric lymph nodes (MLNs) in a type I IFN-dependent manner. Once activated following infection, NK cells produce type II IFN and contribute to IFN-stimulated gene expression in the MLNs, which in turn induces inflammatory DC and T cell responses. Immune depletion of NK cells impairs T1L-induced LOT to newly introduced food antigen. These studies indicate that NK cells modulate the response to dietary antigen in the presence of a viral infection.

The engineered probiotics for the treatment of chronic diseases: A systematic review. J Food Biochem 2022; 46:e14343. [PMID: 35880960 DOI: 10.1111/jfbc.14343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 06/14/2022] [Accepted: 06/21/2022] [Indexed: 11/27/2022]
Abstract
Engineered probiotics (EPs) are a group of probiotics whose proteome is manipulated by biotechnological techniques. EPs have attracted a lot of attention in recent researches for preventing and treating chronic diseases. The current study has been conducted to provide an overview regarding the EPs application in the treatment of chronic disease by a comprehensive systematic review of the published articles up to January 2022. To retrieve the related publications, three databases (PubMed/MEDLINE, Web of Sciences, and Scopus) were searched systematically. Finally, all human (n = 2) and animal (n = 37) studies were included. The included articles evaluated the effects of EPs on treatment of arthritis (n = 3), cancer (n = 2), autoimmune encephalomyelitis (EAE; n = 6), Parkinson disease (PD; n = 1), Alzheimer diseases (AD; n = 1), colitis (n = 11), celiac disease (n = 1), diabetes (n = 8) and cardiovascular disease (CVD; n = 6). Induction of oral tolerance (OT) is the most important mechanism of EPs action in the treatment of chronic disease. Providing oral vaccine and bioactive compounds are the other mechanisms of EPs action. PRACTICAL APPLICATIONS: The current systematic review gathered evidence about the application of EPs in the treatment of chronic diseases. Evidence suggests that EPs have very broad and potent effects in the treatment of chronic and even genetic diseases.

Abstract
Activated cytotoxic CD4 T cells (HLA-DR+) play an important role in the control of EBV infection, especially in cells with latency I (EBNA-1). One of the evasion mechanisms of these latency cells is generated by gp42, which, via peripherally binding to the β1 domain of the β chain of MHC class II (HLA-DQ, -DR, and -DP) of the infected B lymphocyte, can block/alter the HLA class II/T-cell receptor (TCR) interaction, and confer an increased level of susceptibility towards the development of EBV-associated autoimmune diseases or cancer in genetically predisposed individuals (HLA-DRB1* and DQB1* alleles). The main developments predisposing the factors of these diseases are: EBV infection; HLA class II risk alleles; sex; and tissue that is infiltrated with EBV-latent cells, forming ectopic lymphoid structures. Therefore, there is a need to identify treatments for eliminating cells with EBV latency, because the current treatments (e.g., antivirals and rituximab) are ineffective.

Abstract
Celiac disease (CD) comprises over 1% of the world’s population and is a chronic multisystem immune-mediated condition manifested by digestive and/or extradigestive symptoms caused by food intake of gluten. This review looked at the risk of children diagnosed with CD developing SARS-CoV-2 infection and possible severe forms of COVID-19. A better understanding of the interaction and effects of SARS-CoV-2 infection in CD is very important, as is the role of environmental and genetic factors, but especially the molecular mechanisms involved in modulating intestinal permeability with impact on autoimmunity. CD inspired the testing of a zonulin antagonist for the fulminant form of multisystem inflammatory syndrome in children (MIS-C) and paved the way for the discovery of new molecules to regulate the small intestine barrier function and immune responses. Original published works on COVID-19 and CD, new data and points of view have been analyzed because this dangerous virus SARS-CoV-2 is still here and yet influencing our lives. Medical science continues to focus on all uncertainties triggered by SARS-CoV-2 infection and its consequences, including in CD. Although the COVID-19 pandemic seems to be gradually extinguishing, there is a wealth of information and knowledge gained over the last two years and important life lessons to analyze, as well as relevant conclusions to be drawn to deal with future pandemics. Zonulin is being studied extensively in immunoengineering as an adjuvant to improving the absorption of new drugs and oral vaccines.

Abstract
Celiac disease (CeD) is an immune condition induced by the consumption of gluten-containing foods in genetically-predisposed persons. CeD, in addition to digestive disease, is a multisystem disorder. If untreated, it is potentially can be a dangerous disorder and lead to morbidity and even mortality. At present, the only treatment option is a lifelong gluten-free diet (GFD), and all authors recommended this regimen. To the best of our knowledge, there are rare reports of the complete remission of disorder on GFD and reintroduction of a normal diet in affected patients. In this report, we describe five patients with CeD who developed complete remission of clinical symptoms, histopathological changes, and serology on a gluten-containing diet. All patients had CeD based on a positive tissue transglutaminase antibody (TTG IgA) and typical histopathological changes in duodenal biopsy with the complete disappearance of symptoms on the GFD regimen. All patients followed GFD for a mean 4 (±0.54) years. In conclusion, this study has shown that some CeD patients diagnosed in adulthood can recover a normal mucosa after a long period of the gluten-containing diet without relapsing any clinical or biological symptoms of CeD.

Abstract
BACKGROUND Celiac disease (CeD) and inflammatory bowel disease (IBD) are accompanied by impaired immune responses. To study the immune regulation of these diseases, we evaluated the expression levels of pro-inflammatory (IL-8 and IL-17 A) and anti-inflammatory (IL-10) cytokines in intestinal biopsy specimens of CeD and IBD patients in comparison to healthy subjects. METHODS AND RESULTS Intestinal biopsies were collected from 33 patients with IBD, 47 patients with CeD, and 20 healthy individuals. Total RNA was extracted and mRNA expression levels of IL-8, IL-17 A and IL-10 were assessed by qPCR. P-value < 0.05 was considered statistically significant. The expression levels of IL-8 and IL-17 A were higher in biopsies of IBD (UC and CD) and CeD patients compared to the control group (P < 0.05). IBD patients (UC and CD) had higher IL-8 intestinal level than CeD patients (P < 0.0001 and P = 0.0007, respectively). The expression of IL-10 was significantly down-regulated in intestinal biopsies of CeD and IBD patients compared with controls (P < 0.001). In addition, the expression level of this cytokine was significantly lower in IBD patients (P < 0.001 for UC patients and P < 0.0001 for CD patients) than CeD group. CONCLUSIONS The three selected pro- and anti-inflammatory cytokines showed a similar expression pattern in both IBD and CeD patients. As IBD and CeD are immune-mediated disorders and are accompanied by inflammatory events, the understanding of the similarities and differences among them can help researchers to find out useful candidate therapeutic protocols. We suggest that larger cohort studies be organized to achieve more insights into this regulation.

Abstract
Anti-tissue transglutaminase antibodies (anti-tTG) play a vital role in the screening process for coeliac disease (CD). Levels above 30 U/ml suggest a possible diagnosis of CD, prompting further investigation, usually by taking a duodenal biopsy. We report an unusual case of 39-year-old male twins, one presenting with iron deficiency anaemia and the other asymptomatic, with anti-tTG antibodies of >4,965.5 U/ml, an extraordinary level. A duodenal biopsy confirmed a diagnosis of CD and following the adoption of a gluten-free diet, anti-tTG levels were found to decrease back to normal levels. This case demonstrates how CD can cause significant biochemical and histological pathology, but present with mild or no symptoms.

Abstract
Previous studies have shown a relationship between vitamin D and celiac disease (CD), however little evidence is available examining the direct effects of vitamin D on pathological features of this disease. In this study we evaluated the effect of oral administration of different doses of native vitamin D3 (cholecalciferol) in enteropathic mice. Female non-obese diabetic (NOD)/ShiLt.J mice were fed standard or gluten-free diet and administered gliadin (5 μg/kg) to induce a celiac pathology. Healthy control (gluten-free diet, without gliadin) and control for pathology (standard diet, with gliadin) were administered olive oil. All other experimental groups received gliadin and standard diet plus oral cholecalciferol (5, 10, 20, 50 and 130 μg/kg). Serum levels of 25(OH)D3, calcium and zonulin and expression of vitamin D receptor (VDR), CD3 and zonula occludens-1 (ZO-1) by immunohistochemistry as well as intestinal histological and histomorphometric analyses were undertaken. Although no difference in serum levels of 25(OH)D3, calcium or zonulin was observed in cholecalciferol-treated mice vs. healthy controls, a significant improvement in intestinal mucosa pathological features in mice administered cholecalciferol was observed by histological analysis. Villi length was also significantly increased by cholecalciferol in a dose-dependent manner. Immunohistochemical staining revealed increased expression of CD3 and ZO-1 in celiac mice compared to mice receiving high dose (130 μg/kg) cholecalciferol. These findings show the effect of oral cholecalciferol on signature features of CD in a mouse model of CD. Further dose-ranging studies to investigate the efficacy of cholecalciferol for the treatment of CD are warranted.

Abstract
PURPOSE This study aimed to evaluate the diagnosis and determine major and minor criteria of celiac disease (CD) with the malabsorption patterns (MABP) in the small intestine and colon on computed tomography (CT) and additional CT findings. METHODS This retrospective study was conducted with 116 patients diagnosed with CD, 14 CD patients recovering with treatment, and 35 control patients with non-CD. All patients had CT examinations and histopathological diagnoses. The sensitivity, specificity, PPV, NPV, and accuracy values of each CT finding defined in the literature were statistically evaluated. According to the patient and control groups, the numerical values of the findings and the sensitivity and specificity values were measured according to this cut-off value. The distribution of CT findings according to pathological Marsh data was evaluated in CD patients. RESULTS Sensitivity and specificity were found to be higher in small bowel MABP findings, mesenteric hypervascularity, and increased SMV/aorta diameter. There was a numerically significant difference in MDCT findings between the control and pathological Marsh groups. In the ROC analysis performed in terms of the total numerical values of each MDCT finding observed between the groups, it was found that there were more than 7 MDCT findings, 100% sensitivity, and 92% specificity. The presence of four major and three minor criteria or three major and four minor criteria were considered significant. CONCLUSIONS Being aware of CT findings below the iceberg that may suggest CD in abdominal CT examinations performed in patients with atypical clinical and malabsorption findings or other nonspecific findings may prevent diagnostic delay and unnecessary procedures.

Abstract
Background:
Functional Gastrointestinal (GI) disease is a term that refers to a range
of disease conditions involving chronic diarrhea, irritable bowel syndrome, constipation,
inflammatory bowel disease (IBD), and lactose intolerance. Statistical reports have documented
>40% of the world's population is being afflicted by functional GI disorders. Consequences of
frequent intake of antibiotics include mortality of gut microflora, antibiotic-associated diarrhea,
the establishment of antibiotic resistance, and inference with healthy bodily functions. To
overcome the harms of antibiotics, studies are being conducted to determine the potential of
probiotics as alternatives to antibiotics.
Aim of Study:
The purpose of constructing this literature review is to outline the potential
attributes of Kefir and to assess the solitary efficiency of this beverage in the amelioration of GI
disease conditions.
Methodology:
Extraction of data entailed digging of literature hubs including PubMed, PubMed
Central, Research Gate, Science Direct, and Google Scholar, employing a different combination
of keywords to retrieve substantial details. Selection criteria of the articles involved the
published reports of preceding 10 years (2012-2021) that exhibited relevancy with the topic
Conclusion:
Kefir grains having different origins provide a distinct array of antimicrobial
spectrums and are found to be effective against different pathogens. IBDs, diarrheal sicknesses,
and constipation can be alleviated by the consumption of this beverage. Moreover, the probioticantibiotic combination is also essential for the mitigation of several diseases. The synergistic
impact of several microbial strains is vital for the treatment of celiac disease. Lactose maldigestion can be relieved by the consumption of kefir having β-galactosidase enzyme activity.

Abstract
Celiac disease (CD) is a systemic disease triggered by gluten ingestion in genetically predisposed individuals. It manifests primarily as an autoimmune enteropathy associated with specific circulating autoantibodies and a human leukocyte antigen haplotype (HLA-DQ2 or HLA-DQ8). It afflicts roughly 1% of the population, though the majority of patients remain undiagnosed. Diarrhea and malabsorption are classic manifestations of CD; however, both children and adults can be paucisymptomatic and present extraintestinal manifestations such as anemia, osteoporosis, and abnormal liver tests. CD screening is not recommended for the general population, and it should be focused on high-risk groups. CD diagnosis is challenging and relies on serological tests, duodenal histology, and genetic testing. Particularly difficult presentations to manage are seronegative patients, seropositive patients without villus atrophy, and patients who have started a gluten-free diet before the diagnostic workup. The only proven treatment is a lifelong gluten-free diet. We present an in-depth review on the physiopathology and management of CD, with a particular emphasis on diagnostic challenges.

An efficient urine peptidomics workflow identifies chemically defined dietary gluten peptides from patients with celiac disease. Nat Commun 2022; 13:888.

Abstract
Celiac disease (CeD) is an autoimmune disorder induced by consuming gluten proteins from wheat, barley, and rye. Glutens resist gastrointestinal proteolysis, resulting in peptides that elicit inflammation in patients with CeD. Despite well-established connections between glutens and CeD, chemically defined, bioavailable peptides produced from dietary proteins have never been identified from humans in an unbiased manner. This is largely attributable to technical challenges, impeding our knowledge of potentially diverse peptide species that encounter the immune system. Here, we develop a liquid chromatographic-mass spectrometric workflow for untargeted sequence analysis of the urinary peptidome. We detect over 600 distinct dietary peptides, of which ~35% have a CeD-relevant T cell epitope and ~5% are known to stimulate innate immune responses. Remarkably, gluten peptides from patients with CeD qualitatively and quantitatively differ from controls. Our results provide a new foundation for understanding gluten immunogenicity, improving CeD management, and characterizing the dietary and urinary peptidomes. Gluten peptides from wheat enter the bloodstream and are excreted in urine but are yet to be chemically characterised. Here, the authors show by mass spectrometry that quantitative and qualitative differences in urinary peptides can be detected between healthy people and patients with celiac disease.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize the current literature on the subject of linear growth in children and adolescents with or at risk for type 1 diabetes mellitus (T1DM). RECENT FINDINGS Poor glycemic control in T1DM is associated with growth hormone resistance, and improving glycemic control can improve linear growth. Newer reports suggest that the increasingly popular very low carbohydrate diets, may reduce linear growth velocity. SUMMARY Linear growth during childhood is a complex process regulated influenced by genetic, hormonal, nutritional and environmental factors. Linear growth may be impaired in children with T1DM, correlating with poor metabolic control; an extreme example is Mauriac syndrome. This decrement in linear growth appears to be driven in part by a reduction in growth hormone responsiveness, leading to low insulin-like growth factor-1 (IGF-1) levels. Improving glycemic control can lead to improved IGF-1 levels and linear growth. Other factors associated with poor linear growth in T1DM include celiac disease and dietary alterations, with early reports suggesting that very low carbohydrate diets, if not carefully managed, may increase risk of attenuated linear growth. This review examines the latest data regarding the associations between T1DM and linear growth in children.

Abstract
The diagnosis of celiac disease (CD) may be delayed due to non-specific clinical symptoms. The aim of the study was to evaluate the clinical manifestation and diagnostic process of CD in Polish children and adults. Methods: The members of the Polish Coeliac Society (n = 2500) were asked to complete a questionnaire on socio-demographic factors, clinical and diagnostic aspects of CD. The analysis was based on 796 responses from patients with confirmed CD diagnosis, and included 224 (28.1%) children and 572 (71.9%) adults. Results: The mean duration of symptoms prior to CD diagnosis in children was significantly shorter than in adults (p < 0.001), and amounted to 3.1 and 9 years respectively. The most frequent symptoms before CD diagnosis were abdominal pain and bloating in children (70.4%), and chronic fatigue in adults (74.5%). Although almost all CD patients claimed to strictly avoid gluten after CD diagnosis, symptoms were still present in the majority of these respondents. No comorbid diseases were reported by 29.8% of children and by 11.7% of adults (p < 0.001). Conclusions: the results indicate that CD diagnosis is delayed in Poland, especially in adults, and clinicians should be aware of the diversity in CD presentation.

Abstract
Diet has long been understood to have an intricate association with atopic dermatitis, although much remains unelucidated. Skin barrier dysfunction with dysbiosis and consequent impairment of immune tolerance likely underly the pathogenesis of coincident atopic dermatitis and food allergy. There is a wide range of possible skin reactions to food, complicating the diagnosis and understanding of food allergies. Many patients, parents, and providers incorrectly suspect diet as causative of atopic dermatitis symptoms and many have tried elimination diets. This frequently leads to inaccurate labeling of food allergies, contributing to a dangerous spiral of inappropriate testing, referrals, and dietary changes, while neglecting established atopic dermatitis treatment essentials. Alternatively, certain dietary supplements or the introduction of certain foods may be beneficial for atopic dermatitis management or prevention. Greater consensus on the role of diet among providers of patients with atopic dermatitis is strongly encouraged to improve the management of atopic dermatitis.

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
Celiac disease, an autoimmune condition causing gluten intolerance and disrupted absorption of nutrients, predisposes to osteoporosis. The release of pro-inflammatory cytokines, calcium malabsorption, and the activation of osteoclasts represent the main mechanisms responsible for bone derangement. This is evidenced by the low T-score on dual-energy x-ray absorptiometry (DXA) scans in these patients. However, these changes are reversible with the early initiation of a gluten-free diet. Hence, it is important for physicians to consider screening for celiac disease panel in patients presenting with osteoporotic features with no clear etiology.

Abstract
Exocrine pancreatic insufficiency (EPI), an important cause of maldigestion and malnutrition, results from primary pancreatic disease or is secondary to impaired exocrine pancreatic function. Although chronic pancreatitis is the most common cause of EPI, several additional causes exist. These include pancreatic tumors, pancreatic resection procedures, and cystic fibrosis. Other diseases and conditions, such as diabetes mellitus, celiac disease, inflammatory bowel disease, and advanced patient age, have also been shown to be associated with EPI, but the exact etiology of EPI has not been clearly elucidated in these cases. The causes of EPI can be divided into loss of pancreatic parenchyma, inhibition or inactivation of pancreatic secretion, and postcibal pancreatic asynchrony. Pancreatic enzyme replacement therapy (PERT) is indicated for the conditions described above presenting with clinically clear steatorrhea, weight loss, or symptoms related to maldigestion and malabsorption. This review summarizes the current literature concerning those etiologies of EPI less common than chronic pancreatitis, the pathophysiology of the mechanisms of EPI associated with each diagnosis, and treatment recommendations.

Abstract
The gluten-free diet (GFD) has gained popularity beyond its main medical indication as the treatment for gluten-induced immune-mediated disorders such as celiac disease (CD), dermatitis herpetiformis, gluten ataxia, wheat allergy, and non-celiac gluten sensitivity. However, the diet carries some disadvantages such as elevated costs, nutritional deficiencies, and social and psychological barriers. The present work aims to review indications, proven benefits, and adverse events of a gluten-free diet. Close follow-up with patients following the diet is recommended. More data is needed to assess the effectiveness of the diet in managing mental and cognitive disorders and to establish a connection between the brain and gluten.

Abstract
Celiac disease (CD) is not commonly associated with obesity; however, many patients are overweight or obese at time of diagnosis. As the number of people in the United States with obesity continues to rise, it is not known if the prevalence of obesity among patients with CD has also increased. This study utilized an electronic health record database incorporating over 360 individual hospitals in the United States (Explorys Incorporated, Cleveland, OH). Adult patients who had an esophagogastroduodenoscopy at least 1 day prior to reporting of CD from the years 2014 to 2018 formed the study population. From 2014 to 2018, 13,410 patients had a diagnosis of CD. The prevalence of obesity was 45,000/100,000 persons in this CD population. Prevalence of class I (BMI 30-34.9), II (BMI 35-39.9), and III (BMI > 40) obesity in patients with CD continued to rise over the 5-year span. Class I obesity had the highest prevalence and Class II the highest prevalence increase when obesity classes were compared. Clinicians should be aware of obesity as a comorbidity of increasing prevalence when providing longitudinal care for patients with CD.

Abstract
BACKGROUND Celiac disease, an immune-mediated inflammation of the small intestine, occurs in genetically predisposed individuals, and is caused by sensitivity to dietary gluten and related proteins. The global prevalence is approximately 1%. Celiac disease is frequently associated with extra-intestinal manifestations, including iron deficiency anemia, dermatologic eruptions, type 1 diabetes mellitus, thyroid disease, and connective tissue disorders, but is rarely associated with cardiomyopathy. CASE PRESENTATION Our case describes a 33-year-old woman, who presented with exertional dyspnea and fatigue, and was diagnosed with severe iron deficiency anemia and dilated cardiomyopathy, secondary to celiac disease. CONCLUSION High clinical suspicion is needed to identify celiac disease in patients diagnosed with dilated cardiomyopathy, as an improvement in cardiac function has been reported with strict adherence to a gluten-free diet.

Abstract
Celiac disease (CD) is a chronic immune-mediated intestinal disease with genetic susceptibility. It is characterized by inflammatory damage to the small intestine after ingestion of cereals and products containing gluten protein. In recent years, the global prevalence rate of CD has been approximately 1%, and is gradually increasing. CD patients adhere to a gluten-free diet (GFD) throughout their entire life. However, it is difficult to adhere strictly to a GFD. Untreated CD may be accompanied by gastrointestinal symptoms, such as diarrhea, abdominal pain, and extraintestinal symptoms caused by secondary malnutrition. Many studies have suggested that CD is associated with intestinal tumors such as enteropathy-associated T-cell lymphoma (EATL), small bowel cancer (SBC), and colorectal cancer. In this study, we reviewed related studies published in the literature to provide a reference for the prevention and treatment of intestinal tumors in patients with CD. Compared with the general population, CD patients had a high total risk of SBC and EATL, but not colorectal cancer. The protective effect of GFD on CD-related malignancies is controversial. Further studies are needed to confirm whether GFD treatment can reduce the risk of intestinal neoplasms in CD.

Abstract
AIMS Coeliac disease (CD) is an autoimmune disorder with a prevalence ≤2% that causes an immune reaction to gluten. Growth retardation (GR) generally accompanies CD due to gastrointestinal complications and should be treated as early as possible along with initiation of a gluten-free diet. The aim of this study was to determine the indicators of GR in patients with CD. METHODS This single-centre retrospective study included paediatric outpatients with CD. All patients were diagnosed with CD via serological analysis and upper gastrointestinal endoscopy if necessary. Patient records were obtained from Adana City Training and Research Hospital. Patients that were diagnosed with GR accompanying CD were given oral nutritional supplements and followed-up every 3-6 months. Statistical relationships between demographics, and anthropometric measurements, duration of breastfeeding, gluten contact time, diet duration, presenting complaints and serological findings were evaluated. RESULTS This study included 169 paediatric outpatients between ages 1 and 18. Longer symptom duration and shorter breastfeeding duration were significantly correlated with GR accompanying CD (P = 0.007 and P = 0.029, respectively). Vomiting was the only symptom that was correlated with the presence of GR (P = 0.010). Helicobacter pylori infection was not correlated with the presence of GR (P = 0.277). CONCLUSIONS GR should be treated as early as possible to reduce the severity of CD and a 6 months sole breastfeeding followed by solid foods accompanied by breastfeeding for 2 years is crucial for preventing GR. Moreover, vomiting as a presenting complaint in patients with CD might be indicative of the presence of GR.

Abstract
Developing deep learning models to analyze histology images has been computationally challenging, as the massive size of the images causes excessive strain on all parts of the computing pipeline. This paper proposes a novel deep learning-based methodology for improving the computational efficiency of histology image classification. The proposed approach is robust when used with images that have reduced input resolution, and it can be trained effectively with limited labeled data. Moreover, our approach operates at either the tissue- or slide-level, removing the need for laborious patch-level labeling. Our method uses knowledge distillation to transfer knowledge from a teacher model pre-trained at high resolution to a student model trained on the same images at a considerably lower resolution. Also, to address the lack of large-scale labeled histology image datasets, we perform the knowledge distillation in a self-supervised fashion. We evaluate our approach on three distinct histology image datasets associated with celiac disease, lung adenocarcinoma, and renal cell carcinoma. Our results on these datasets demonstrate that a combination of knowledge distillation and self-supervision allows the student model to approach and, in some cases, surpass the teacher model's classification accuracy while being much more computationally efficient. Additionally, we observe an increase in student classification performance as the size of the unlabeled dataset increases, indicating that there is potential for this method to scale further with additional unlabeled data. Our model outperforms the high-resolution teacher model for celiac disease in accuracy, F1-score, precision, and recall while requiring 4 times fewer computations. For lung adenocarcinoma, our results at 1.25× magnification are within 1.5% of the results for the teacher model at 10× magnification, with a reduction in computational cost by a factor of 64. Our model on renal cell carcinoma at 1.25× magnification performs within 1% of the teacher model at 5× magnification while requiring 16 times fewer computations. Furthermore, our celiac disease outcomes benefit from additional performance scaling with the use of more unlabeled data. In the case of 0.625× magnification, using unlabeled data improves accuracy by 4% over the tissue-level baseline. Therefore, our approach can improve the feasibility of deep learning solutions for digital pathology on standard computational hardware and infrastructures.

Abstract
Background Prevalence of chronic gastrointestinal diseases has been rising amongst ethnic minority populations in Western countries, despite the first-generation migrants originating from countries of low prevalence. Differences caused by genetic, environmental, cultural, and religious factors in each context may contribute towards shaping experiences of ethnic minority individuals living with primary bowel conditions. This review aimed to explore the experiences of ethnic minority patients living with chronic bowel conditions. Methods We conducted a systematic scoping review to retrieve qualitative, quantitative, and mixed methods studies from eight electronic databases, and manually searched reference lists of frequently cited papers. Results Fourteen papers met the inclusion criteria: focussing on inflammatory bowel disease, irritable bowel syndrome, and coeliac disease. Core themes were narratively analysed. South Asians had limited understanding of inflammatory bowel disease and coeliac disease, hindered by language and literacy barriers, particularly for older generations, suggesting that culturally relevant information is needed. Family support was limited, and Muslim South Asians referred to religion to understand and self-manage inflammatory bowel disease. Ethnic minority groups across countries experienced: poor dietary intake for coeliac disease and inflammatory bowel disease, cultural conflict in self-managing diet for inflammatory bowel disease which increased anxiety, and there was a need for better quality of, and access to, healthcare services. British ethnic minority groups experienced difficulties with IBD diagnosis/misdiagnosis. Conclusions Cultural, religious, and social contexts, together with language barriers and limited health literacy influenced experiences of health inequalities for ethnic minority patients living with chronic bowel diseases.

Abstract
BACKGROUND Epidemiological studies of adult glioma have identified genetic syndromes and 25 heritable risk loci that modify individual risk for glioma, as well increased risk in association with exposure to ionizing radiation and decreased risk in association with allergies. In this analysis, we assess whether there is a shared genome-wide genetic architecture between glioma and atopic/autoimmune diseases. METHODS Using summary statistics from a glioma genome-wide association studies (GWAS) meta-analysis, we identified significant enrichment for risk variants associated with gene expression changes in immune cell populations. We also estimated genetic correlations between glioma and autoimmune, atopic, and hematologic traits using linkage disequilibrium score regression (LDSC), which leverages genome-wide single-nucleotide polymorphism (SNP) associations and patterns of linkage disequilibrium. RESULTS Nominally significant negative correlations were observed for glioblastoma (GB) and primary biliary cirrhosis (rg = -0.26, P = .0228), and for non-GB gliomas and celiac disease (rg = -0.32, P = .0109). Our analyses implicate dendritic cells (GB pHM = 0.0306 and non-GB pHM = 0.0186) in mediating both GB and non-GB genetic predisposition, with GB-specific associations identified in natural killer (NK) cells (pHM = 0.0201) and stem cells (pHM = 0.0265). CONCLUSIONS This analysis identifies putative new associations between glioma and autoimmune conditions with genomic architecture that is inversely correlated with that of glioma and that T cells, NK cells, and myeloid cells are involved in mediating glioma predisposition. This provides further evidence that increased activation of the acquired immune system may modify individual susceptibility to glioma.

Abstract
The protein/peptide profiles of gluten during yogurt fermentation were evaluated using an optimized multiplex-competitive ELISA by preparing yogurts incurred with gluten at different concentrations and by varying certain fermentation conditions. Analysis indicated that epitope-specific responses with antibody binding to glutenin epitopes decreased less during longer fermentation times or at higher starter culture concentrations relative to gliadins. Incomplete proteolysis was observed after 24 h of fermentation, which became more efficient as fermentation time was increased. Western blot confirmed the results of ELISA. Cluster analysis indicated that out of the investigated parameters, fermentation time is the only parameter that could affect the overall gluten protein/peptide profiles during yogurt fermentation. This parameter needs consideration in evaluating the suitability of calibrant(s) to be used with the multiplex-competitive ELISA or any other methods to ensure accurate quantitation of gluten in yogurts and potentially in other foods with similar fermentation chemistry. A small-scale multilaboratory evaluation indicated that the multiplex-competitive ELISA has good analytical reproducibility (average interlaboratory % CV of 28-41%).

Abstract
Celiac disease is a chronic inflammatory condition characterized by activation of the immune system in response to deamidation of gluten peptides brought about by tissue transglutaminase-2 (TG2). Overexpression of interleukin-15 (IL-15) in the intestinal epithelium and the lamina propria leads to the dysregulation of the immune system, leading to epithelial damage. The goal of this study was to develop an RNA interference therapeutic strategy for celiac disease using a combination of TG2 and IL-15 gene silencing in the inflamed intestine. TG2 and IL-15 silencing siRNA sequences, along with scrambled control, were encapsulated in a nanoparticle-in-microsphere oral system (NiMOS) and administered in a poly(I:C) mouse model of celiac disease. Single TG2 and IL-15 siRNA therapy and the combination showed effective gene silencing in vivo. Additionally, it was found that IL-15 gene silencing alone and combination in the NiMOS significantly reduced other proinflammatory cytokines. The tissue histopathology data also confirmed a reduction in immune cell infiltration and restoration of the mucosal architecture and barrier function in the intestine upon treatment. Overall, the results of this study show evidence that celiac disease can be potentially treated with an oral microsphere formulation using a combination of TG2 and IL-15 RNA interference therapeutic strategies.

Abstract
OBJECTIVE Celiac disease is a chronic disease that affect small bowel by making its villi become atrophic. Various environmental and genetic factors have been identify as inducing factors for celiac disease. Most of the patients has one of the HLA DQ forms. Although the prevalence of these genes are variable in different areas of the world, we do not have a comprehensive information about this issue in our region. Thus the aim of present study is to investigate the prevalence of HLA DQ typing of patients who visited Emam Reza Gastroenterology clinic of Shiraz(IRAN). METHODS In this case-control study all under 18 years old children who were diagnosed with celiac disease and have visited Emam Reza gastroenterology clinic were investigated. The diagnosis of celiac disease was made by history, physical exam, serologic test, and histopathology of duodenal biopsy. Blood sample was taken and HLA typing performed using PCR method at Motahari clinic cytology laboratory. Also those people who neither them self nor their first degree relatives were not case of celiac disease and underwent HLA typing for other reason were identified as control group. The statistical analysis was done using SPSS 18 software. The p value < 0.05 was identified as statistically significant. RESULTS A total of 139 patients with celiac disease and 146 normal children were studied. The mean age of the patient with celiac disease were 9.1 years old with standard deviation of 3.4 years old. 64% of the celiac patients were girls and 36% were boys. While this proportion was 54.4% for boy and 48.6% for girls in control group. The most common HLA in celiac patients group were HLA DQ2 and 8 but the most common ones in control group were HLA DQ 8 and 5. Failure to Thrive were the most common signs of the celiac patients with a prevalence of 60 children. Total IgA titer were normal in 98.6% of the patients and TTG IgA titer were positive in 93.5% of the patients. The most common co existing disease with the celiac disease were diabetes with a prevalence of 30 children (66.7%). CONCLUSION present study reveals that the prevalence of the HLA DQ2 and 8 among patients with celiac disease is 72.6% and 53% in our normal population.

Abstract
BACKGROUND AND OBJECTIVES Celiac disease is an autoimmune disease occurring in about 1 in 100 people worldwide. Early diagnosis and efficient treatment are crucial in mitigating the complications that are associated with untreated celiac disease, such as intestinal lymphoma and malignancy, and the subsequent high morbidity. The current diagnostic methods using small intestinal biopsy histopathology, endoscopy, and video capsule endoscopy (VCE) involve manual interpretation of photomicrographs or images, which can be time-consuming and difficult, with inter-observer variability. In this paper, a machine learning technique was developed for the automation of biopsy image analysis to detect and classify villous atrophy based on modified Marsh scores. This is one of the first studies to employ conventional machine learning to automate the use of biopsy images for celiac disease detection and classification. METHODS The Steerable Pyramid Transform (SPT) method was used to obtain sub bands from which various types of entropy and nonlinear features were computed. All extracted features were automatically classified into two-class and multi-class, using six classifiers. RESULTS An accuracy of 88.89%, was achieved for the classification of two-class villous abnormalities based on analysis of Hematoxylin and Eosin (H&E) stained biopsy images. Similarly, an accuracy of 82.92% was achieved for the two-class classification of red-green-blue (RGB) biopsy images. Also, an accuracy of 72% was achieved in the classification of multi-class biopsy images. CONCLUSION The results obtained are promising, and demonstrate the possibility of automating biopsy image interpretation using machine learning. This can assist pathologists in accelerating the diagnostic process without bias, resulting in greater accuracy, and ultimately, earlier access to treatment.

Abstract
We report on the case of a 61-year-old male who initially presented with a progressive myoclonus and an intention tremor and was subsequently diagnosed with celiac disease. His neurological symptoms improved with anti-epileptic therapy and a gluten-free diet. Possible explanations include a milder disease phenotype or an epileptic component to his myoclonic movement disorder. This case highlights findings of a progressive myoclonic movement disorder, likely linked to celiac disease, and stresses the importance of a gluten-free diet in the management of the neurological manifestations of celiac disease.

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
OBJECTIVES During the past decades, there has been a shift in the clinical presentation of coeliac disease (CD) to nonclassical, oligosymptomatic, and asymptomatic forms. We assessed clinical presentation of CD in children and adolescents in Central Europe. METHODS Paediatric gastroenterologists in 5 countries retrospectively reported data of their patients diagnosed with CD. Clinical presentation was analyzed and the differences among very young (<3 years) and older children and adolescents were studied. RESULTS Data from 653 children and adolescents (median age 7 years 2 months; 63.9% girls) from Croatia, Germany, Hungary, Italy, and Slovenia were available for the analysis. One fifth (N = 134) of all children were asymptomatic. In symptomatic children, the most common leading symptom was abdominal pain (33.3%), followed by growth retardation (13.7%) and diarrhoea (13.3%). The majority of symptomatic children (47.6%; N = 247) were polysymptomatic. Abdominal pain was the most common symptom in polysymptomatic (66.4%) as well as in monosymptomatic children (29.7%). Comparing clinical presentation of CD in very young children (younger than 3 years) with older children (3 years or older), we found that symptoms and signs of malabsorption were significantly more common in younger (P < 0.001), whereas abdominal pain and asymptomatic presentation were more common in older children and adolescents (both P < 0.001). CONCLUSION In children with CD, abdominal pain has become the most common symptom. However, in younger children, symptoms of malabsorption are still seen frequently. This raises a question about the underlying mechanism of observed change in clinical presentation in favour of nonclassical presentation and asymptomatic disease at certain age.

Gut-Ex-Vivo system as a model to study gluten response in celiac disease. Cell Death Discov 2021; 7:45.

Abstract
Celiac disease (CD) is a complex immune-mediated chronic disease characterized by a consistent inflammation of the gastrointestinal tract induced by gluten intake in genetically predisposed individuals. Although initiated by the interaction between digestion-derived gliadin, a gluten component, peptides, and the intestinal epithelium, the disorder is highly complex and involving other components of the intestine, such as the immune system. Therefore, conventional model systems, mainly based on two- or three-dimension cell cultures and co-cultures, cannot fully recapitulate such a complex disease. The development of mouse models has facilitated the study of different interacting cell types involved in the disorder, together with the impact of environmental factors. However, such in vivo models are often expensive and time consuming. Here we propose an organ ex vivo culture (gut-ex-vivo system) based on small intestines from gluten-sensitive mice cultivated in a dynamic condition, able to fully recapitulate the biochemical and morphological features of the mouse model exposed to gliadin (4 weeks), in 16 h. Indeed, upon gliadin exposure, we observed: i) a down-regulation of cystic fibrosis transmembrane regulator (CFTR) and an up-regulation of transglutaminase 2 (TG2) at both mRNA and protein levels; ii) increased intestinal permeability associated with deregulated tight junction protein expression; iii) induction and production of pro-inflammatory cytokines such as interleukin (IL)-15, IL-17 and interferon gamma (IFNγ); and iv) consistent alteration of intestinal epithelium/villi morphology. Altogether, these data indicate that the proposed model can be efficiently used to study the pathogenesis of CD, test new or repurposed molecules to accelerate the search for new treatments, and to study the impact of the microbiome and derived metabolites, in a time- and cost- effective manner.

The impact of symptoms on quality of life before and after diagnosis of coeliac disease: the results from a Polish population survey and comparison with the results from the United Kingdom. BMC Gastroenterol 2021; 21:99. [PMID: 33663388 PMCID: PMC7934494 DOI: 10.1186/s12876-021-01673-0] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Accepted: 02/17/2021] [Indexed: 12/22/2022] Open
Abstract
Background Coeliac disease (CD) is characterised by diverse clinical symptoms, which may cause diagnostic problems and reduce the patients’ quality of life. A study conducted in the United Kingdom (UK) revealed that the mean time between the onset of coeliac symptoms and being diagnosed was above 13 years. This study aimed to analyse the diagnostic process of CD in Poland and evaluate the quality of life of patients before and after CD diagnosis. In addition, results were compared to the results of the original study conducted in the UK. Methods The study included 2500 members of the Polish Coeliac Society. The patients were asked to complete a questionnaire containing questions on socio-demographic factors, clinical aspects and quality of life, using the EQ-5D questionnaire. Questionnaires received from 796 respondents were included in the final analysis. Results The most common symptoms reported by respondents were bloating (75%), abdominal pain (72%), chronic fatigue (63%) and anaemia (58%). Anaemia was the most persistent symptom, with mean duration prior to CD diagnosis of 9.2 years, whereas diarrhoea was observed for the shortest period (4.7 years). The mean duration of any symptom before CD diagnosis was 7.3 years, compared to 13.2 years in the UK. CD diagnosis and the introduction of a gluten-free diet substantially improved the quality of life in each of the five EQ-5D-5L health dimensions: pain and discomfort, anxiety and depression, usual activities, self-care and mobility (p < 0.001), the EQ-Index by 0.149 (SD 0.23) and the EQ-VAS by 30.4 (SD 28.3) points. Conclusions Duration of symptoms prior to the diagnosis of CD in Poland, although shorter than in the UK, was long with an average of 7.3 years from first CD symptoms. Faster CD diagnosis after the onset of symptoms in Polish respondents may be related to a higher percentage of children in the Polish sample. Introduction of a gluten-free diet improves coeliac patients’ quality of life. These results suggest that doctors should be made more aware of CD and its symptoms across all age groups.

Abstract
BACKGROUND AND OBJECTIVES Based on some previous observational studies, there is a theory that suggests a potential relationship between Helicobacter pylori (H. pylori) colonization and celiac disease (CeD); however, the type of this relationship is still controversial. Therefore, we aimed to conduct a systematic review and meta-analysis to explore all related primary studies to find any possible association between CeD and human H. pylori colonization. DATA SOURCES Studies were systematically searched and collected from four databases and different types of gray literature to cover all available evidence. After screening, the quality and risk of bias assessment of the selected articles were evaluated. SYNTHESIS METHODS Meta-analysis calculated pooled odds ratio (OR) on the extracted data. Furthermore, heterogeneity, sensitivity, subgroups, and publication bias analyses were assessed. RESULTS Twenty-six studies were included in this systematic review, with a total of 6001 cases and 135512 control people. The results of meta-analysis on 26 studies showed a significant and negative association between H. pylori colonization and CeD (pooled OR = 0.56; 95% CI = 0.45-0.70; P < 0.001), with no publication bias (P = 0.825). The L'Abbé plots also showed a trend of having more H. pylori colonization in the control group. Among subgroups, ORs were notably different only when the data were stratified by continents or risk of bias; however, subgroup analysis could not determine the source of heterogeneity. CONCLUSIONS According to the meta-analysis, this negative association might imply a mild protective role of H. pylori against celiac disease. Although this negative association is not strong, it is statistically significant and should be further considered. Further investigations in both molecular and clinic fields with proper methodology and more detailed information are needed to discover more evidence and underlying mechanisms to clear the interactive aspects of H. pylori colonization in CeD patients.

Abstract
The substitution of wheat gluten in the food industry is a relevant research area because the only known treatment for celiac disease is abstinence from this protein complex. The use of gluten-free cereals in dough systems has demonstrated that the viscoelastic properties of gluten cannot be achieved without the modification of the protein fraction. The quality of the final product is determined by the ability of the modification to form a matrix similar to that of gluten and to reach this, different methods have been proposed and tested. These procedures can be classified into four main types: chemical, enzymatic, physical, and genetic. This article provides a comprehensive review of the most recent research done in protein modification of cereal and pseudocereals for gluten substitution. The reported effects and methodologies for studying the changes made with each type of modification are described; also, some opportunity areas for future works regarding the study of the effect of protein modifications on gluten-free products are presented.

Abstract
ABSTRACT Objective To determine the frequency of Human leukocyte antigen alleles and to verify the association of the presence of these alleles with symptoms and other diseases related to celiac disease in patients with autoimmune thyroid diseases. Methods A questionnaire on the symptoms and diseases associated with celiac disease was applied. Genomic deoxyribonucleic acid was extracted by collecting cells from the oral mucosa. The alleles (DQA1*0501; DQB1*0201; DRB1*04) were identified by means of the polymerase chain reaction. Results A total of 110 patients with autoimmune thyroid diseases participated in this study. It was observed that 66.4% of the individuals carried at least one of the alleles assessed and that 58.2% of the individuals were positive for at least one of the DQ2 alleles (DQA1*0501; DQB1*0201) and out of these 18.2% were positive for both DQ2 alleles (DQA1*0501; DQB1*0201). With regard to DQ8 (DRB1*04), 21.8% of the studied population was positive for this allele and 3.6% was positive for both DQ2 (DQA1*0501; DQB1*0201) and DQ8 (DRB1*04). A significant association was found between the presence of the DRB1*04 allele and gastrointestinal symptoms (p=0.02). A significant association of the DRB1*04 allele with type 1 diabetes mellitus (p=0.02) was observed. Conclusion The genetic profiles most commonly associated with celiac disease, such as DQ2 (DQA1*0501; DQB1*0201) and DQ8 (DRB1*04) were around 20.0% prevalent in the studied population. These are risk haplotypes for celiac disease especially when symptoms and diseases related to celiac disease are present. Therefore, it is important to screen patients to investigate a potential diagnosis for celiac disease.
