Abstract
PURPOSE OF REVIEW Immune checkpoint inhibitor (ICI) therapy revolutionized the treatment of multiple solid and hematologic malignancies. Yet, with it came profound inflammatory toxicities that mimic autoimmune diseases, termed immune-related adverse events (irAEs). Prominent among these is gastrointestinal inflammation, including a spectrum of gastritis, enteritis, and colitis. Here we synthesize an approach to immune checkpoint related enterocolitis (irEC) - including diagnostics and therapeutics - underpinned by new insights into the mechanism behind these phenomena. RECENT FINDINGS This review presents updated insights on how to approach irEC, including novel approaches to selective immunosuppressive therapy, the role of fecal microbiota transplant, and the underlying cellular mechanisms of irEC. This review provides an update on irEC diagnosis and therapy, with considerations of new therapies and special patient populations. The field of gastrointestinal irAEs requires additional investigation, which will ultimately provide the tools required for patients to continue to receive life-saving ICI therapy.

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.

Diagnostic Accuracy of IgA Anti-Transglutaminase and IgG Anti-Deamidated Gliadin for Diagnosis of Celiac Disease in Children under Two Years of Age: A Systematic Review and Meta-Analysis. Nutrients 2021; 14:nu14010007. [PMID: 35010880 PMCID: PMC8746847 DOI: 10.3390/nu14010007] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 12/15/2021] [Accepted: 12/16/2021] [Indexed: 01/18/2023] Open
Abstract
The need of adding the determination of anti-deamidated gliadin peptide (DGP) IgG to anti-transglutaminase (TTG) IgA antibodies for diagnosis of celiac disease (CD) in children <2 years of age is controversial. We performed a systematic review and meta-analysis to evaluate, by head-to-head comparison, the diagnostic accuracy of TTG IgA and DGP IgG antibodies. We searched PubMed, MEDLINE, and Embase databases up to January 2021. The diagnostic reference was intestinal biopsy. We calculated the sensitivity and specificity of these tests and the odds ratio (OR) between the tests. Fifteen articles were eligible for the systematic review and ten were eligible for the meta-analysis. Sensitivity and specificity were 0.96 (95% confidence interval (CI), 0.91–0.98) and 0.96 (95% CI, 0.85–0.99) for DGP IgG and 0.93 (95% CI, 0.88–0.97) and 0.98 (95% CI, 0.96–0.99) for TTG IgA, respectively. TTG IgA specificity was significantly higher (OR 9.3 (95% CI, 2.3–37.49); p < 0.001) while the sensitivity of DGP IgG was higher without reaching statistical significance (OR: 0.6 (95% CI, 0.24–1.51); p = 0.28). Both the meta-analysis and the systematic review showed that some children with early CD are missed without the DGP IgG test. In children <2 years of age, TTG IgA is the best CD screening test; however, the addition of DGP IgG may increase the diagnostic sensitivity.

Abstract
BACKGROUND Dermatitis herpetiformis (DH) is considered a skin celiac disease (CD). The individuals can be seen by primary care professionals or by dermatologists that could refer the patient to a gastroenterologist. OBJECTIVE The study aimed to investigate the clinical profile of patients diagnosed with DH and referred to a gastroenterologist and evaluate the treatment response. METHODS We retrospectively studied patients with DH referred to the same gastroenterologist at a private office in Curitiba, Brazil, between January 2010 to December 2019. We included adult patients with a confirmed DH diagnosis. Symptoms, clinical signs, laboratory and histological data, as well as treatment response, were collected. RESULTS Thirty-three patients were studied (60.6% women, mean age at diagnosis 40.8±12.61 years). The median delay for DH diagnosis was four years. Skin involvement was mild in 33.3%, moderate in 18.2%, and severe in 48.5%. The more frequent gastrointestinal complaints were abdominal distension (78.8%), flatulence (75.7%), and gastroesophageal reflux (51.5%). Depression and anxiety were observed in 81.8% and anemia in 51.1%. A higher prevalence of bone disorders was associated with higher age at DH diagnosis (P=0.035). Duodenal biopsy showed changes in all patients. Improvement after treatment only with a gluten-free diet (GFD) plus dapsone was verified in 81.2%. CONCLUSION Patients with DH referred to a gastroenterologist showed a high frequency of gluten intolerance and systemic complaints. Duodenal histological alterations were found in all the cases. The treatment based on GFD plus dapsone was effective in most patients.

Abstract
BACKGROUND AND AIM Serum transglutaminase antibodies (tTGs) are used for celiac disease screening and to monitor celiac disease patients on a gluten-free diet (GFD). The need for histology of duodenal biopsies to assess mucosal healing after a GFD is still a matter of debate. We evaluated whether tTGs are adequate to detect the persistence of histological lesions of duodenal mucosa in celiac patients after a GFD. METHODS In total 253 patients with histological diagnosis of celiac disease according to Marsh criteria, both at the time of diagnosis (T0) and 18-24 months after starting a GFD (T2), were included. tTGs were evaluated both at T0 and T2; endomysial antibodies (EMAs) only at T0. RESULTS At T0, 9.2% of patients had both tTG and EMA negative values, despite the evidence of duodenal lesions: 33.3% of Marsh 1, 14.3% of Marsh 2 and 5.2% of Marsh 3. At T2, tTGs were negative in 77.6% of patients: 82.2% of Marsh 0, 79.8% of Marsh 1, 70.0% of Marsh 2 and 59.1% of Marsh 3. At T2, approximately 60% of patients with the persistence of mucosal atrophy had negative tTGs. At T0, tTG median values were lower in patients with Marsh 1 and Marsh 2 than patients with Marsh 3 (P < 0.001), whereas no difference was found at T2 regardless of Marsh's grade (P = 0.4). CONCLUSIONS The results of our study highlight how histologic evaluation of duodenal biopsies remains the gold standard for both celiac disease diagnosis and the evaluation of mucosal recovery after 18-24 months of a GFD.

Abstract
Celiac disease is an autoimmune enteropathy triggered by the ingestion of gluten in genetically susceptible individuals. In patients with suspected celiac disease, measurement of serum IgA antibodies to tissue transglutaminase-2 has a high sensitivity and specificity and is the first screening test that should be ordered. The diagnosis of celiac disease is based on the presence of mucosal damage in small intestinal biopsies in patients having circulating celiac disease-specific antibodies. Celiac disease management includes lifelong adherence to a gluten-free diet and continuous long-term follow-up.

Abstract
INTRODUCTION Celiac disease (CD) is an immune-mediated disease caused by ingesting gluten-containing foods and is characterized mainly by malabsorptive diarrhea. Furthermore, distinguishing between mild disease and asymptomatic individuals is critical and necessitates a high level of clinical suspicion. Short stature, delayed puberty, bone abnormalities, neurological problems, and intestinal cancer can all be consequences of a delayed diagnosis. This study aimed to determine the prevalence of celiac disease among our community's recurrent diarrhea patients. METHODS This was a cross-sectional study aimed at determining the frequency of celiac disease in patients with chronic diarrhea. One hundred eighty-eight patients between the ages of 18 and 60 years who had chronic diarrhea lasting greater than three months were enrolled in this study. Stratification was utilized to control for modifiers. A p-value of ≤ 0.05 was considered significant. RESULTS A total of 74.5% of patients (n=140) were male, while 25.5% (n=48) were female with a mean age of 38.48±10.85 years. The average duration of celiac disease symptoms was 8.17± 3.75 months. Celiac disease was found in 12.2% (n=23) of the individuals. Also, 21% of individuals with a positive family history of CD devolved CD, compared to those without prior CD family history (p=0.01). CONCLUSIONS In individuals with chronic diarrhea for more than three months, the prevalence of celiac disease was determined to be 12.2% (n=23). There was a statistically significant difference between those with a positive family history of CD and those who did not have the condition.

Abstract
INTRODUCTION Capsule endoscopy has proven its utility in diagnosing villous atrophy and lymphoma in patients with celiac disease. Recently, a novel capsule endoscopy system was introduced which enables the examination of the small and large bowel. So far, it has not been evaluated in patients with celiac disease. OBJECTIVE The primary objective of this study was to evaluate the novel panintestinal capsule endoscopy system in patients with celiac disease. METHODS Eleven patients with histologically proven celiac disease (Marsh 0-IV), who underwent a panintestinal capsule endoscopy between March 2018 and April 2019 at our institution, were included in this retrospective single-center study. All patients performed standard bowel preparation prior to the examination. Diagnostic yield, safety and therapeutic impact were analyzed. In addition, the correlation between capsule endoscopy findings and the histology of the duodenal mucosa was assessed. RESULTS Panintestinal capsule endoscopy was feasible and produced an acceptable visualization quality in all cases. Concordance of capsule endoscopy findings with the Marsh classification showed a good correlation (r = 0.8). No lymphomas were detected. Evaluation of the colon revealed diminutive polyps (median size 4 mm) in 18% of patients. CONCLUSIONS The novel panintestinal capsule endoscopy system shows a fair correlation with the Marsh classification in patients with celiac disease. It is also capable of identifying colon polyps. Therefore, the novel panintestinal capsule endoscopy system can be considered for patients with celiac disease and an indication for capsule endoscopy.

Abstract
Celiac disease (CD) is an immune-mediated disease, caused by gluten, occurring in people with genetic predisposition. The course of the disease can vary and includes both intestinal and extra-intestinal manifestations. Many patients are undiagnosed for many years and some of them, in particular with nonspecific symptoms or asymptomatic, might never be diagnosed. We present a rare case of a patient, who’s first and practically the only symptom of the disease was a pathological fracture of the ribs. In addition, despite the lack of clinical symptoms of malabsorption syndrome, malnutrition and proteinuria, we observed profound hypoalbuminemia and hypoproteinemia. This case suggests that CD diagnostic should be undertaken in evaluation of every patient with osteoporotic fractures and hypoalbuminemia.

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
Dermatologists play a critical role in diagnosing and managing nutritional deficiencies as they often present with cutaneous findings. Traditionally, nutritional dermatoses are taught in the context of developing countries, famine, population displacement, and poor healthcare access; however, in the United States, common risk factors include chronic liver disease, alcoholism, psychiatric disease, bariatric surgery, inflammatory bowel disease, and hemodialysis. Additionally, nutritional dermatoses may be underdiagnosed in the United States and result in increased morbidity and utilization of hospital resources. There is a need for providers in developed nations to identify these deficiencies, and this review aims to meet that practice gap and provide relevant context to these diseases for dermatologists. This two-part review series will focus on the epidemiology, impact, appearance, and diagnostic modalities for micronutrient deficiencies, including zinc, selenium, copper, and vitamins A and C in part one. The companion review will focus on the B-complex vitamins.

Abstract
1: ESGE recommends that, where there is a suspicion of eosinophilic esophagitis, at least six biopsies should be taken, two to four biopsies from the distal esophagus and two to four biopsies from the proximal esophagus, targeting areas with endoscopic mucosal abnormalities. Distal and proximal biopsies should be placed in separate containers.Strong recommendation, low quality of evidence. 2: ESGE recommends obtaining six biopsies, including from the base and edge of the esophageal ulcers, for histologic analysis in patients with suspected viral esophagitis.Strong recommendation, low quality of evidence. 3: ESGE recommends at least six biopsies are taken in cases of suspected advanced esophageal cancer and suspected advanced gastric cancer.Strong recommendation, moderate quality of evidence. 4: ESGE recommends taking only one to two targeted biopsies for lesions in the esophagus or stomach that are potentially amenable to endoscopic resection (Paris classification 0-I, 0-II) in order to confirm the diagnosis and not compromise subsequent endoscopic resection.Strong recommendation, low quality of evidence. 5: ESGE recommends obtaining two biopsies from the antrum and two from the corpus in patients with suspected Helicobacter pylori infection and for gastritis staging.Strong recommendation, low quality of evidence. 6: ESGE recommends biopsies from or, if endoscopically resectable, resection of gastric adenomas.Strong recommendation, moderate quality of evidence. 7: ESGE recommends fine-needle aspiration (FNA) and fine-needle biopsy (FNB) needles equally for sampling of solid pancreatic masses.Strong recommendation, high quality evidence. 8: ESGE suggests performing peroral cholangioscopy (POC) and/or endoscopic ultrasound (EUS)-guided tissue acquisition in indeterminate biliary strictures. For proximal and intrinsic strictures, POC is preferred. For distal and extrinsic strictures, EUS-guided sampling is preferred, with POC where this is not diagnostic.Weak recommendation, low quality evidence. 9: ESGE suggests obtaining possible non-neoplastic biopsies before sampling suspected malignant lesions to prevent intraluminal spread of malignant disease.Weak recommendation, low quality of evidence. 10: ESGE suggests dividing EUS-FNA material into smears (two per pass) and liquid-based cytology (LBC), or the whole of the EUS-FNA material can be processed as LBC, depending on local experience.Weak recommendation, low quality evidence.

Prevalence of celiac disease in China: Meta-analysis and serological survey in high-risk populations. J Dig Dis 2021; 22:645-655. [PMID: 34482631 DOI: 10.1111/1751-2980.13049] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Revised: 08/25/2021] [Accepted: 09/01/2021] [Indexed: 12/11/2022]
Abstract
OBJECTIVE To summarize data from a serological survey of high-risk populations in Guangdong Province, China, and to perform a meta-analysis to investigate the prevalence and seroprevalence of celiac disease (CD) in the Chinese general and high-risk populations. METHODS We collected data from the serological survey of high-risk population of CD in Guangdong Province, China (N = 1390) by testing their serum tissue transglutaminase immunoglobulin A (tTG-IgA), deamidated gliadin peptides immunoglobulin A (DGP-IgA) and deamidated gliadin peptides immunoglobulin G (DGP-IgG). Additionally, a literature search was performed on PubMed, EMBASE, Cochrane Library and three Chinese databases for articles published up to 20 December 2020 to estimate the pooled prevalence and seroprevalence of CD in China. RESULTS In the serological survey, 0.94% (13/1390) of individuals were positive for CD antibodies. In a meta-analysis of 18 studies, the seroprevalence of CD in the general Chinese population was 0.27% (95% confidence interval [CI] 0.02%-0.71%). While that in the high-risk population was 8.34% (95% CI 4.90%-12.54%) (odds ratio 7.27, 95% CI 4.06-13.04). The prevalence of biopsy-confirmed CD in high-risk Chinese populations was 4.44% (95% CI 1.53%-8.58%). The seroprevalence of CD varied with patients' geographical origin, being higher in northern China than in southern China. CONCLUSIONS Early diagnosis of CD by serological screening in high-risk population and generous serological testing in those with vague symptoms, especially in northern China, are recommended.

Abstract
PURPOSE OF REVIEW This review highlights literature from the past year and explores the impact on current understanding of celiac disease pathogenesis, diagnosis, and management. RECENT FINDINGS In contrast to earlier clinical trials, recent data suggests that early gluten introduction may protect against the development of celiac disease. Celiac disease is underdiagnosed, associated with high burden of disease and linked to excess mortality risk, yet, there remains considerable uncertainty regarding the utility of mass screening in asymptomatic individuals. The gut microbiome is increasingly implicated in celiac disease pathogenesis, although the exact mechanism is undefined. Probiotics have been proposed as a disease-modifying option for celiac disease but most studies assessing efficacy are of low-quality. Patients with celiac disease do not appear to be at increased risk of contracting or developing adverse outcomes from COVID-19. Little is known about the pathogenesis of nonceliac gluten sensitivity; however, recent findings suggest an autoimmune basis for the condition. SUMMARY Current understanding of celiac disease continues to advance, though significant knowledge gaps remain. Large, rigorous, prospectively designed studies are needed to further characterize celiac disease pathogenesis, management and therapeutic options.

Abstract
Celiac disease (CeD) is a frequent immune-mediated disease that affects not only the small intestine but also many extraintestinal sites. The role of gluten proteins as dietary triggers, HLA-DQ2 or -DQ8 as major necessary genetic predisposition, and tissue transglutaminase (TG2) as mechanistically involved autoantigen, are unique features of CeD. Recent research implicates many cofactors working in synergism with these key triggers, including the intestinal microbiota and their metabolites, nongluten dietary triggers, intestinal barrier defects, novel immune cell phenotypes, and mediators and cytokines. In addition, apart from HLA-DQ2 and -DQ8, multiple and complex predisposing genetic factors and interactions have been defined, most of which overlap with predispositions in other, usually autoimmune, diseases that are linked to CeD. The resultant better understanding of CeD pathogenesis, and its manifold manifestations has already paved the way for novel therapeutic approaches beyond the lifelong strict gluten-free diet, which poses a burden to patients and often does not lead to complete mucosal healing. Thus, supported by improved mouse models for CeD and in vitro organoid cultures, several targeted therapies are in phase 2-3 clinical studies, such as highly effective gluten-degrading oral enzymes, inhibition of TG2, cytokine therapies, induction of tolerance to gluten ingestion, along with adjunctive and preventive approaches using beneficial probiotics and micronutrients. These developments are supported by novel noninvasive markers of CeD severity and activity that may be used as companion diagnostics, allow easy-to perform and reliable monitoring of patients, and finally support personalized therapy for CeD.

Abstract
BACKGROUND Previous studies investigating the prevalence of celiac disease (CD) in individuals with autoimmune hepatitis (AIH) have shown highly variable results. We therefore aimed to examine the prevalence of CD in individuals with AIH. METHODS Two professional librarians searched PubMed, EMBASE, Cochrane and Web of Science Core Collection up until 7 February 2020. The search terms included 'celiac disease', 'celiac', 'transglutaminases', 'gluten', 'gliadin', 'EMA', 'TTG' and 'villous' combined with 'autoimmune', 'hepatitis', 'ANA', 'SMA' and 'LKM'. This search yielded 2419 unique publications. A systematic review based on the PRISMA guidelines resulted in 31 articles eligible for full text review. Fifteen articles were deemed relevant, with 8 being included in our main analysis. A fixed-effect inverse variance-weighted model was used, and heterogeneity was calculated. RESULTS Our main analysis included 567 individuals with AIH from eight studies, where biopsy-verified CD (equivalent to Marsh III) was seen in 23 individuals (4.1%). The pooled prevalence of CD in AIH was 3.5% (95% CI = 1.6%-5.3%) (heterogeneity: P = .874; I2 = 0.0%), which is clearly higher than the 1% CD seen in most general populations. When also including studies where CD had been diagnosed through positive serology without biopsy (15 studies: n = 1817 individuals with AIH), the pooled prevalence of CD was 2.9% (95% CI = 2.1%-3.8%) (heterogeneity: P < .001; I2 = 66.8%). CONCLUSION Our results demonstrate a higher prevalence of CD in individuals with AIH compared to the general population. CD screening may be considered in patients with AIH.

Abstract
Diabetes mellitus (DM) is a chronic metabolic disorder with a multi-systemic involvement, the gastrointestinal (GI) system being one of them. In this study, we have compiled and analyzed findings from various studies to conclude that peripheral insulin resistance and hyperglycemia are the two key factors that play a role in the pathogenesis of the web of disorders associated with diabetes. These two key factors, when clubbed with autoimmunity, autonomic neuropathy, and genetic and environmental factors, play a substantial role in the development of GI disorders in DM. This article examines GI disorders such as gastric autonomic neuropathy, non-alcoholic fatty liver disease (NAFLD), celiac disease (CD), etc. It also highlights the importance of regular screening and assessment of DM in preventing the GI tangent of the disease. A prompt blood glucose control through lifestyle modifications, dietary management, and weight reduction, coupled with pharmacotherapy for existing DM, can lead to a better outcome and an optimistic perspective on the disease.

Abstract
BACKGROUND There are limited studies on the seronegative celiac disease from the Indian subcontinent. The aim of this study was to assess the prevalence, pathological, genetic, and clinical profile of patients with seronegative celiac disease. METHODS This prospective observational study was conducted in the Department of Gastroenterology, SMS Hospital, Jaipur, between October 2017 to March 2019. Consecutive patients with seronegative celiac disease with age ≥ 3 years were enrolled for the assessment of demography, clinical features, histological findings, celiac serology, genetic analysis, and response to gluten-free diet. RESULTS Out of total of 312 patients with celiac disease, 13 (4.16 %) patients (median age 25 years [range 5-46 years], 10 female) were diagnosed as having seronegative celiac disease. Presenting symptoms were chronic diarrhea in nine (69.23%), abdominal pain in six (46.15%), weight loss in five (38.46%), and short stature in two (15.38 %) patients. On histological analysis, Marsh stage 2 was seen in five (38.46%), Marsh 3c in two (15.38%), Marsh 3a in three (23.07%), and Marsh 3b in three (23.07%) patients. On HLA analysis, HLA-DQ2.5 was seen in six (46.15%) patients, HLA-DQ2.2 in five (38.46%), and HLA-DQ8 in two (15.38%) patients. CONCLUSION The prevalence of seronegative celiac disease in our study was 4.16%. The most common symptoms were chronic diarrhea and abdominal pain, and the histological grade was Marsh stage 2.

Abstract
Celiac disease (CD) is an autoimmune disorder that affects genetically predisposed individuals who are sensitive to gluten and related proteins. It affects children and adults with increasing prevalence in the older age groups. Both adaptive and innate immune responses play role in CD pathogenesis which results in damage of lamina propria and deposition of intraepithelial lymphocytes. There are other proposed mechanisms of CD pathogenesis like gastrointestinal infections, intestinal microbiota, and early introduction of gluten. The diagnosis of CD is based on clinical symptoms and serological testing, though a majority of cases are asymptomatic, and small intestinal biopsies are required to confirm the diagnosis. Celiac disease is generally associated with other autoimmune diseases, and it is advisable to test these patients for diseases like type 1 diabetes mellitus, Addison’s disease, thyroid diseases, inflammatory bowel disease, and autoimmune hepatitis. The patient with a new diagnosis of CD requires close follow-up after starting treatment to see symptom improvement and check dietary compliance. A newly diagnosed patient is advised to follow with a dietitian to better understand the dietary restrictions as about 20% of patients stay symptomatic even after starting treatment due to noncompliance or poor understanding of diet restrictions. The most effective treatment for CD is a gluten-free diet, but work on non-dietary therapy is in process and few medications are in the clinical trial phase.

Abstract
Down syndrome (DS) is a unique genetic disease caused by the presence of an extra copy of chromosome 21, which carries four of the six interferon receptor (IFN-R) genes on its long arm. Recent studies reporting higher levels of interferon-stimulated gene (ISG) expression in primary immune cells studied ex vivo have suggested that the additional copies of the IFN-R genes in DS result in mild interferonopathy. In this review, we analyze the potential clinical and immunological impacts of this interferonopathy in DS. We performed a literature review to explore the epidemiology and risks of celiac disease, type 1 diabetes, thyroid dysfunction, mucocutaneous manifestations, infectious diseases (including COVID-19), and Alzheimer’s disease in individuals with DS relative to the general population with or without iatrogenic exposure to interferons. We analyzed immunophenotyping data and the current experimental evidence concerning IFN-R expression, constitutive JAK-STAT activation, and ISG overexpression in DS. Despite the lack of direct evidence that implicating this mild interferonopathy directly in illnesses in individuals with DS, we highlight the challenges ahead and directions that could be taken to determine more clearly the biological impact of interferonopathy on various immune-related conditions in DS.

Abstract
The use of pure oats (oats cultivated with special care to avoid gluten contamination from wheat, rye, and barley) in the gluten-free diet (GFD) represents important nutritional benefits for the celiac consumer. However, emerging evidence suggests that some oat cultivars may contain wheat gliadin analog polypeptides. Consequently, it is necessary to screen oats in terms of protein and epitope composition to be able to select safe varieties for gluten-free applications. The overall aim of our study is to investigate the variability of oat protein composition directly related to health-related and techno-functional properties. Elements of an oat sample population representing 162 cultivated varieties from 20 countries and the protein composition of resulting samples have been characterized. Size distribution of the total protein extracts has been analyzed by size exclusion-high performance liquid chromatography (SE-HPLC) while the 70% ethanol-extracted proteins were analyzed by RP-HPLC. Protein extracts separated into three main groups of fractions on the SE-HPLC column: polymeric proteins, avenins (both containing three subgroups based on their size), and soluble proteins, representing respectively 68.79–86.60, 8.86–27.72, and 2.89–11.85% of the total protein content. The ratio of polymeric to monomeric proteins varied between 1.37 and 3.73. Seventy-six reversed phase-HPLC-separated peaks have been differentiated from the ethanol extractable proteins of the entire population. Their distribution among the cultivars varied significantly, 6–23 peaks per cultivar. The number of appearances of peaks also showed large variation: one peak has been found in 107 samples, while 15 peaks have been identified, which appeared in less than five cultivars. An estimation method for ranking the avenin-epitope content of the samples has been developed by using MS spectrometric data of collected RP-HPLC peaks and bioinformatics methods. Using ELISA methodology with the R5 antibody, a high number of the investigated samples were found to be contaminated with wheat, barley, or rye.

Reliability of the Multiplex CytoBead CeliAK Immunoassay to Assess Anti-tTG IgA for Celiac Disease Screening. Front Med (Lausanne) 2021; 8:731067. [PMID: 34621764 PMCID: PMC8491777 DOI: 10.3389/fmed.2021.731067] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2021] [Accepted: 08/05/2021] [Indexed: 01/16/2023] Open
Abstract
Background and Objective: The diagnosis of Celiac Disease (CD) is first based on the positivity for specific serological markers. The CytoBead CeliAK immunoassay simultaneously measures antibodies (IgA) directed to tissue transglutaminase (tTG), endomysium (EMA), and deamidated gliadin (DG), in addition to providing a control for total IgA levels. The aim of this study is to assess the reliability of this multiplex assay to detect anti-tTG IgA positive patients, compared with a conventional single-parameter enzyme-linked immunosorbent assay (ELISA). Methods: Serum samples from 149 pediatric patients were assessed by both CytoBead CeliAK immunoassay and ELISA, in order to evaluate their concordance for the measurement of anti-tTG IgA. Results: The measurement of anti-tTG IgA by CytoBead CeliAK immunoassay basically showed a complete concordance rate with the conventional and single-parameter ELISA, according to the respective cutoff values (3 U/ml and 10 U/ml). Conclusions: Our comparative analysis demonstrates a substantial equivalency between multiplex CytoBead CeliAK assay and the single-parameter conventional ELISA to assess anti-tTG IgA antibody in the context of the screening for CD in children. Importantly, CytoBead CeliAK assay could present some preanalytic, analytic, and economic advantages.

Abstract
Although, the association between celiac disease (CD) and selective immunoglobulin A deficiency (SIgAD) has been known for more than fifty years, the procedures for diagnosing and monitoring patients with both conditions are still far from definitive. When serological markers were introduced as pre-bioptic investigations, it was immediately clear that searching for specific IgA antibodies without checking total serum IgA could lead to a failure in diagnosing IgA-deficient CD patients, while specific IgG antibodies could be useful as additional tests, because they are frequently found in the serum of affected patients. Nonetheless, until recently the diagnosis of CD in IgA-deficient patients was based on the few, fragmentary and often contradictory data available in literature. The introduction of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) guidelines in 2012 provided the current criteria for diagnosing CD in IgA-deficient patients, although some issues remained open, such as the selection of patients who should undergo specific IgG antibody testing and the choice of the most reliable IgG-based test for both diagnosis and follow-up. A real-life study recently assessed the impact of the 2012 ESPGHAN guidelines in diagnosing and monitoring CD in SIgAD patients, highlighting several pitfalls that can lead to operational uncertainties and difficulties in patient management. In the present report, the evolution of diagnostic tools and criteria for CD in SIgAD patients has been critically assessed, both strengths and open issues have been highlighted, and future perspectives for improving the current diagnostic protocols have been suggested.

Abstract
Few studies have correlated pediatric endoscopic and histologic impressions of duodenal biopsies. Method: This is a retrospective study on children undergoing upper gastrointestinal endoscopy over a period of 11 years. We investigated concordance between the gross endoscopic and histopathologic characteristics of pediatric duodenal biopsies. Results: Of 1793 children enrolled in the study, duodenal pathology was observed in 72.3%. The gross endoscopic findings showed a low sensitivity of 38.9%, specificity of 99.2%, PPV of 99.2%, and NPV of 38.3%. Concordance between the gross endoscopic and histopathologic analysis was 55.6%. Conclusion: This study showed a higher rate of pediatric duodenal pathologies than gross assessment. This emphasizes the value for acquiring routine duodenal biopsies from grossly normal mucosa.

Iron Deficiency in Celiac Disease: Prevalence, Health Impact, and Clinical Management. Nutrients 2021; 13:nu13103437.

Abstract
Iron is an essential nutrient to life and is required for erythropoiesis, oxidative, metabolism, and enzymatic activities. It is a cofactor for mitochondrial respiratory chain enzymes, the citric acid cycle, and DNA synthesis, and it promotes the growth of immune system cells. Thus, iron deficiency (ID) leads to deleterious effects on the overall health of individuals, causing significant morbidity. Iron deficiency anemia (IDA) is the most recognized type of anemia in patients with celiac disease (CD) and may be present in over half of patients at the time of diagnosis. Folate and vitamin B12 malabsorption, nutritional deficiencies, inflammation, blood loss, development of refractory CD, and concomitant Heliobacter pylori infection are other causes of anemia in such patients. The decision to replenish iron stores and the route of administration (oral or intravenous) are controversial due, in part, to questions surrounding the optimal formulation and route of administration. This paper provides an algorithm based on the severity of symptoms; its impact on the health-related quality of life (HRQL); the tolerance and efficiency of oral iron; and other factors that predict a poor response to oral iron, such as the severity of histological damage, poor adherence to GFD, and blood loss due to mucosal lesions.

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
BACKGROUND Family screening has been advocated as a means to reduce the major underdiagnosis of coeliac disease. However, the precise risk of the disease in relatives and the impact of patient- and relative-related individual factors remain obscure. AIMS To investigate the individual risk of coeliac disease among patients' relatives. METHODS Altogether 2943 relatives of 624 index patients were assessed for the presence of previous coeliac disease diagnosis, or were screened for the disease. Coeliac disease-associated human leucocyte antigen (HLA) genotype was determined from all participants. The association between individual factors and new screening positivity was assessed by logistic regression. RESULTS There were 229 previously diagnosed non-index relatives with coeliac disease and 2714 non-affected (2067 first-degree, 647 more distant) relatives. Of these 2714 relatives, 129 (4.8%) were screening-positive (first-degree 5.1%, second-degree 3.6%, more distant 3.5%). The combined prevalence of the previously diagnosed and now detected cases in relatives was 12.2% (6.3% clinically detected, 5.9% screen-detected). In univariate analysis, age <18 years at diagnosis (odds ratio 1.60, 95% CI 1.04-2.45) in index, and age 41-60 years (1.73, 1.10-2.73), being a sibling (1.65, 1.06-2.59) and having the high-risk genotype (3.22, 2.01-5.15 DQ2.5/2.5 or DQ2.5/2.2 vs other risk alleles) in relatives were associated with screening positivity. Only high-risk HLA remained significant (2.94, 1.80-4.78) in multivariable analysis. CONCLUSIONS Unrecognised coeliac disease was common among at-risk relatives even in a country with an active case-finding policy, and also in relatives more distant than first-degree. The presence of a high-risk genotype was the most important predictor for screening positivity. ClinicalTrials.gov identifier NCT03136731.

Abstract
Irritable bowel syndrome (IBS) is among the most common diagnoses made by medical providers and its symptoms are common causes for health care consultation. IBS is characterized by abdominal pain associated with abnormal stool consistency and/or frequency and is widely considered a diagnosis of exclusion, despite abundant evidence contradicting such an approach. A positive diagnosis is achieved through application of symptom-based clinical criteria, careful history and physical examination, evaluation for alarm sign/symptoms, and judicious use of diagnostic testing. This article reviews the symptom-based criteria for IBS and utility of diagnostic tests commonly included in the evaluation of IBS symptoms.

Abstract
Coeliac disease (CD) is an autoimmune gastroenteropathy triggered by gliadin and gliadin-tissue transglutaminase (tTG) complexes. CD is one of the few autoimmune diseases with an accurate, non-invasive serological test. Anti-endomysial, anti-tTG and anti-deaminated gliadin peptides (DGP) antibodies are currently used for serological tests with tTG ELISAs being the superior test. Duodenal biopsy, although invasive, is the gold standard for CD diagnosis. HLA genotyping and flow cytometry can also be used as supplementary tests. The incidence of CD is rising globally although the reasons for this remain unclear. In addition, the true incidence of coeliac disease in African populations remains unknown although recent work suggests that South African populations express the alleles associated with this disease. This review examines the pathogenesis and diagnosis of coeliac disease and considers novel and innovative biomarkers in its diagnosis specifically in an African population.

Abstract
OBJECTIVE Gastrointestinal problems are often seen in children with cerebral palsy, although the etiology and underlying mechanisms are not fully understood. Recent data point to significantly elevated levels of IgG antibody to dietary gluten in cerebral palsy independent of celiac disease, a gluten-mediated autoimmune enteropathy. We aimed to further characterize this antibody response by examining its subclass distribution and target reactivity in the context of relevant patient symptom profile. METHODS Study participants included children with cerebral palsy (n = 70) and celiac disease (n = 85), as well as unaffected controls (n = 30). Serum IgG antibody to gluten was investigated for subclass distribution, pattern of reactivity towards target proteins, and relationship with gastrointestinal symptoms and motor function. RESULTS The anti-gluten IgG antibody response in the cerebral palsy cohort was constituted of all 4 subclasses. In comparison with celiac disease, however, IgG1, IgG2, and IgG3 subclasses were significantly lower, whereas the IgG4 response was significantly higher in cerebral palsy. Within the cohort of cerebral palsy patients, levels of anti-gluten IgG1, IgG3, and IgG4 were greater in those with gastrointestinal symptoms, and the IgG3 subclass antibody correlated inversely with gross motor function. The anti-gluten IgG antibodies targeted a broad range of gliadin and glutenin proteins. CONCLUSIONS These findings reveal an anti-gluten IgG subclass distribution in cerebral palsy that is significantly different from that in celiac disease. Furthermore, the observed association between IgG subclass and symptom profile is suggestive of a relationship between the immune response and disease pathophysiology that may indicate a role for defects in gut immune and barrier function in cerebral palsy.

Abstract
Introduction & Aim: Anti-tissue transglutaminase antibody (tTGA) titer is used during the follow-up of celiac patients to evaluate gluten-free diet (GFD) responsiveness. However, no clear data are available on this issue. The aim of this study was to evaluate tTGA significance during celiac disease (CD) monitoring. Methods: From January 2017 to January 2020, consecutive CD patients on a GFD with persistent positive tTGA were enrolled. Antibody titres were evaluated on a yearly basis from CD diagnosis to the last follow-up. Urinary gluten detection tests, duodenal histology and capsule enteroscopy (CE) were performed. A tTGA-positive cohort was compared with a control group composed of 212 treated CD patients with negative tTGA. Results: 65 patients (12% males, median age at enrollment and CD diagnosis, 37 (14–86) and 31 (1–76), respectively, median follow up 4 (1–26) years) presented with positive tTGA during follow-up. Overall, the tTGA titres were 3 (1–79) fold increased (ULN). Three different tTGA trends were recognized: (I) 36 (55%) patients with a progressive titres decrease; (II) 16 (25%) patients with a fluctuating behavior; (III) 13 (20%) patients with a steady state or increased titres. tTGA+ patients did not present with different clinical and demographic parameters. Duodenal atrophy was present in 10% vs. 36% of the tTGA positive vs. negative group (p < 0.005), respectively. Gluten detection results were positive in 3 (8%) cases, all in the III group. In tTGA+ patients, CE did not identify any CD-related complications. Conclusions: tTGA positivity during CD follow up did not present a relevant clinical significance without association with autoimmune comorbidities and mucosal damage.

Abstract
Background: Autism spectrum disorders (ASD) are a heterogeneous group of neurodevelopmental conditions whose etiopathogenesis derives from a complex interaction between genetic liability and environmental factors. In this framework, mounting evidence suggests that immune system dysfunction could be a risk factor contributing to the development of ASD in at least a subpopulation of individuals. In particular, some studies suggest an association between celiac disease (CD)—a long-term autoimmune disorder that primarily affects the small intestine triggered by the ingestion of gluten—and ASD, while others hypothesized a random link. This investigation aimed to evaluate the prevalence of CD in a large sample of school-aged children with ASD and to characterize their clinical profile. Methods: Medical records of 405 children with ASD aged 5–11 years (mean age: 7.2 years; SD: 1.8 years) consecutively referred to a tertiary-care university hospital between January 2014 and December 2018 were reviewed; among them, 362 had carried out serological testing for CD. Results: Nine patients with positive CD serology were identified, eight of which satisfied the criteria for CD diagnosis. The estimated CD prevalence in ASD children was 2.18% (95% CI, 0.8–3.7), which was not statistically different (1.58%; p = 0.36) from that of an Italian population, matched for age range, considered as a control group (95% CI, 1.26–1.90). Three out of the eight ASD patients with CD did not have any symptoms suggestive of CD. Conclusions: Our findings did not show a higher prevalence of CD in ASD children than in the control population, but could suggest the utility of routine CD screening, given its frequent atypical clinical presentation in this population.

Increased Prevalence of Celiac Disease in Patients with Cystic Fibrosis: A Systematic Review and Meta-Analysis. J Pers Med 2021; 11:jpm11090859. [PMID: 34575636 PMCID: PMC8470465 DOI: 10.3390/jpm11090859] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 08/25/2021] [Accepted: 08/26/2021] [Indexed: 12/11/2022] Open
Abstract
Objectives: Immune regulation seems to be altered in cystic fibrosis (CF), thus potentially predisposing patients to developing autoimmune diseases (AID). In this meta-analysis, we aimed to evaluate the prevalence of celiac disease (CeD) among CF patients as by far the most commonly reported autoimmune disease in this population and, secondly, to review the observations on other, less frequently studied autoimmune diseases. Methods: We conducted a systematic literature search for studies that discussed AIDs among CF patients. Following standard selection and data collection, we calculated pooled raw prevalence with 95% confidence intervals (CI) for biopsy-verified CeD and seropositivity. Results: Out of the 21 eligible studies, 15 reported on CeD. Pooled prevalence of biopsy-verified CeD was 1.8% (CI 1.1–2.7%) according to a homogeneous dataset from six prospective, consecutive screening studies, while it proved to be 2.3% (CI 1.1–4.7%) according to a heterogeneous dataset from the other studies. Tissue transglutaminase IgA positivity was detected in 4.5% of CF cases (CI 2.8–6.9%), while tissue transglutaminase IgA–endomysial antibody IgA double positivity was found in 2.4% of them (CI 1.5–3.9%). Findings on other AIDs were strongly limited. Conclusions: The pooled prevalence of CeD in CF seemed to be more than twice as high compared to the global prevalence; therefore, routine screening of CeD could be considered in CF.

Frater JL. Trends in iron deficiency anemia research 2001-2020: A bibliometric analysis. World J Meta-Anal 2021; 9:389-404. [DOI: 10.13105/wjma.v9.i4.389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Revised: 05/17/2021] [Accepted: 07/12/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Iron deficiency anemia has a worldwide impact on individual health and national and international economies, with an estimated one-third of the world population being iron deficient.
AIM To evaluate the iron deficiency literature published between 2001-2020 with an emphasis on: (1) Identification of collaborative research networks most active in this field; (2) Research topics of greatest importance; and (3) Analysis of the most-cited papers published between 2001-2020 and the most cited papers in 5-year intervals during this period to assess for emerging trends in research in this area.
METHODS A search of Clarivate Analytics World of Science Core Collection was performed for the topic “iron deficiency anemia”, limited to document type (article or review), language (English), and time span (2001-2020). The following data were extracted from these articles: Year of publication, journal, study design, country of first author, and number of citations. The metadata derived from the search were used to identify publication trends in iron deficiency anemia research and their distribution in countries/regions and institutions. Network visualization by VOSviewer (Leiden University) was performed to identify international collaborative groups and research hotspots.
RESULTS The search identified 4828 publications. Three international collaborative networks were identified: United States, Canada, and India; Turkey, China, and Japan; and England and other European countries. Five research areas were hotspots: Epidemiologic aspects of iron deficiency anemia, biochemical aspects of iron deficiency anemia, clinical evaluation of causes of iron deficiency anemia, causes of iron deficiency anemia, and bioavailability of dietary iron. Subset analysis of the top-10 overall cited papers, and the top-10 cited papers for each 5-year increment beginning in 2001 showed that the largest number of highly cited papers were from the field of epidemiology, the smallest number from the field of bioavailability of dietary iron.
CONCLUSION The literature on iron deficiency anemia has a high citation rate compared to studies of other topics using similar methodology and is heavily biased toward studies from the United States and epidemiologic studies.

Abstract
BACKGROUND AND AIM Autoimmune atrophic gastritis (AAG) is characterized by a variable spectrum of gastric and extra-gastric symptoms and has been associated with other autoimmune diseases. It is still unknown whether AAG patients have a higher risk of coeliac disease (CeD) or of any other particular duodenal histological damage. Our study aimed at evaluating the duodenal histological findings and the risk of CeD in patients with AAG, with and without other concurrent autoimmune diseases. METHODS We retrospectively collected all the histological findings of the adult patients undergoing upper gastrointestinal endoscopy with concurrent duodenal and gastric biopsies at our gastroenterology unit between 2015 and 2018 and who were regularly followed up at our centre. Date of endoscopy evaluation, endoscopy indication, data on previous CeD diagnosis and on other autoimmune-associated diseases, and a description of histological diagnosis were recorded. RESULTS Of the 2,423 evaluated endoscopies, 209 patients had an AAG diagnosis (8.6%). One hundred thirty-nine patients, aged 57.4 (standard deviation 13.2) years, were regularly followed up at our centre and were included. Of them, 4 subjects had a previous diagnosis of CeD and one had CeD diagnosis at index endoscopy. Additionally, 8 patients had an isolated increase of intraepithelial lymphocytes (IELs, 6%) and 2 villous atrophy with a normal IEL count. The risk of CeD in AAG was not modulated by the presence of other concurrent autoimmune diseases. CONCLUSIONS We support the screening of all AAG patients with CeD autoantibodies. Findings of isolated IEL or villous atrophy are not exclusively related to CeD.

Abstract
Celiac disease (CD) is an autoimmune chronic inflammatory disease occurring in genetically predisposed individuals in response to the intake of gluten. Clinical presentation can be heterogeneous. Iron-deficient anemia (IDA) is one of the most common extra-intestinal manifestations of CD. Although IDA usually reverts with a gluten-free diet (GFD), some patients show persistent IDA, the mechanisms of which are poorly understood. Recent studies suggest an association between the rs855791 polymorphism in the TMPRSS6 gene and persistent IDA in adults with CD. The current study aimed to assess the potential link between rs855791 and persistent IDA in pediatric patients with CD. The study included 106 children diagnosed with CD between 2015 and 2019. Clinical and blood parameters (including blood count, serum iron) were collected at diagnosis and after ≥12 months of GFD, and the rs855791 genotype was assessed for each patient. IDA was present at diagnosis in 25 patients (23.6%); only three (3%) had persistent IDA after GFD. The prevalence of rs855791 genotypes was 9% (n = 10) for TT, 53% (n = 56) for CT, and 38% (n = 40) for CC. There was a tendency toward a higher proportion of the T allele in patients with IDA and lower hemoglobin in the TT genotype but without statistical significance. An association between rs855791 and persistent IDA was not observed. These findings suggest that persistent IDA is uncommon in pediatric patients with CD. The prevalence of rs855791 in children with CD is reported for the first time.

Abstract
BACKGROUND Celiac disease (CD) is an autoimmune disease characterized by immune reaction mostly to wheat gluten. The diagnosis is based on clinical, serological and histological findings in patients ingesting gluten. Cases that the clinical profile indicates CD and the autoantibodies are negative bring so a dilemma for the professional, as the risk of missed the diagnosis or a delay at the same. OBJECTIVE To show the importance of correct diagnosis of cases with seronegative celiac disease (SNCD). METHODS Ten cases of SNCD Brazilian patients were retrospectively studied (2013 to 2019). Data of clinical complaints, autoantibodies, IgA serum levels, histological findings and HLA-DQ2/DQ-8 were compiled. Dual-X densitometry, delay at diagnosis, previous autoimmune diseases and family history of CD were also checked. RESULTS All SNCD patients presented clinical symptoms of CD, with confirmed diagnosis by histological findings of the duodenal mucosa and HLA-DQ2 and/or HLA-DQ8 positivity. All patients had normal IgA levels and negative autoantibodies (IgA-anti-transglutaminase and anti-endomysial). Dual-X densitometry detected osteopenia in two women and osteoporosis in two males, all with low levels of vitamin D. Delay diagnostic ranged from 1 to 19 years. Familiar occurrence of CD was reported in 40% of the cases. After one year of gluten-free diet, eight patients refer improve of symptoms, while duodenal biopsies, done in five cases, showed histological improvement. CONCLUSION Patients who demonstrate the clinical profile of celiac disease with negative serology and normal levels of IgA, especially those who have family members with celiac disease, should be submitted to duodenal biopsies to look for histological findings.

Abstract
Chronic diarrhea is defined by symptoms lasting longer than 4 weeks. It is a common problem that affects up to 5% of the adult population. Different pathophysiologic mechanisms involve numerous causes, including drug side effects, postoperative anatomic and physiologic alterations, intestinal and colonic wall abnormalities, inflammatory or malabsorption causes, pancreatobiliary diseases, and functional or gut-brain axis disorders associated with dysbiosis or gastrointestinal motility alterations. Due to such a broad differential diagnosis, it is important to categorize chronic diarrhea into five main groups: drug side effect, postoperative, postinfectious, malabsorptive, inflammatory, and functional. The present review is a narrative analysis of the diagnostic approach, emphasizing key aspects of the clinical history, the utility of biomarkers (in breath, stool, urine, and serology) and malabsorption and motility tests, the role of radiologic and endoscopic studies, and the most common histologic findings. A diagnostic algorithm aimed at determining etiology and personalizing therapy is also proposed.

Abstract
Objective: To assess the prevalence of gluten-free diet (GFD) among school-age children in Olmsted County, Minnesota, and compare it with the prevalence of celiac disease (CD) in the same age group. Methods: We performed a population-based study in Olmsted County using a survey to collect information from the six school districts in the county for the academic year 2014–2015. The survey contained questions to (1) assess the prevalence of GFD among school-age children in the public schools of Olmsted County; (2) assess the prevalence of CD among school-age children in Olmsted County; and (3) determine the indications for GFD in these children. We used the infrastructure of the Rochester Epidemiology Project (REP) to calculate the prevalence of CD in children aged 4–18 years in December 2014. Results: Using the REP data, we identified sixty patients with CD in the county aged 4–18 years; the prevalence of CD among school students in 2014 was 193.6/100,000. The prevalence of GFD in Olmsted County children, however, was higher, at 265/100,000 according to the survey from the school districts. The prevalence of GFD was highest in Rochester, the largest city. GFD was more common among children in secondary schools. Conclusion: According to our study, there are more children on GFD than the actual cases of CD in Olmsted County during the study period. This finding could be related to an increased number of children without CD who are following GFD for other indications.

Abstract
PURPOSE The shift towards an obese phenotype in celiac disease (CD) patients increases risk of morbidity and mortality. Bariatric surgery (BS) is the gold standard treatment for obesity. Few studies have explored the role of BS in patients with CD. This study aimed to assess the effectiveness and safety of BS in this population. MATERIAL AND METHODS This is a retrospective matched case-control (1:5) study of adult patients with confirmed CD who underwent BS at our institution from 1998 to 2018. Demographics, operative data, post-operative outcomes, complications, and nutritional parameters were collected. RESULTS Seventy-eight patients (mostly Caucasian females) were included. Thirteen had confirmed CD and were compared with 65 controls. The most common type of BS was the RYGB. The percent of total body weight loss (%TWL) was similar for both groups at 6, 12, 18, 24, and 36 months, with the highest weight loss being at 12 months: %TWL 28.4 (20.2-38.4) for CD, n=13; vs. 29.1 (19.6-39.3) for non-CD, n=49; p=0.8. Obesity-associated co-morbidities greatly and comparably improved in both groups. Patients with CD had no complications after BS. Post-BS malodorous and oily stools were more common among patients with CD (23.1% vs. 4.6%, p=0.03). Micronutrient deficiencies were common and comparable among both groups with iron and vitamin D being the most common deficiencies. Gluten-free diet (GFD) non-adherence post-operatively was associated with a higher incidence of post-BS abdominal pain (60.0% vs. 0.0%, p=0.012). CONCLUSIONS BS is safe and effective in patients with CD. Close monitoring is necessary to ensure compliance with GFD and vitamin supplementation. KEY POINTS • Bariatric surgery leads to significant weight loss in celiac disease (CD) patients. • Mid- and long-term weight loss does not differ between patients with and without CD. • Obesity-associated co-morbidities significantly improve after surgery in CD patients. • The incidence of post-surgical complications is not higher in CD patients.

Abstract
BACKGROUND While the small intestine is the main site of disease, many other organs are affected by celiac disease (CeD). Dental enamel defects (DED) are common in patients with CeD, and these are one of the indicators of CeD, even when no other symptom of CeD is present. Data on dental and oral cavity manifestations in Asian patients with CeD are scanty. The purpose of the current study was to evaluate dental and oral manifestations in Asian patients with CeD. METHODS We recruited 118 patients with biopsy-confirmed CeD (36 treatment naïve and 82 on follow-up for at least 1 year on gluten-free diet [GFD]) and 40 controls. Diagnosis was made as per the standard criteria. Oral and dental manifestations were evaluated by a dental surgeon. The DED were evaluated according to Aine's criteria. RESULTS Overall higher number of patients with CeD (66.9%), both treatment naïve (69.4%) and those on GFD (65.8%) had DED in comparison to controls (20%) (odds ratio, 8.1, 95% confidence interval [CI] 3.4-19.2; p<0.001). Specific/bilaterally symmetrical DED were significantly higher in patients with CeD than controls. Recurrent aphthous ulcers were also significantly higher in patients with CeD. Approximately 80.6% and 63.4% treatment-naïve patients and those on GFD, respectively reported dry mouth sensation, which was significantly higher than the controls. CONCLUSION Almost two-third of patients with CeD had DED. Physicians and dietitians caring for patients with CeD should be trained in identification of DED and other oral manifestations of CeD.

Abstract
In the last 10,000 years, wheat has become one of the most important cereals in the human diet and today, it is widely consumed in many processed food products. Mostly considered a source of energy, wheat also contains other essential nutrients, including fiber, proteins, and minor components, such as phytochemicals, vitamins, lipids, and minerals, that together promote a healthy diet. Apart from its nutritional properties, wheat has a set of proteins, the gluten, which confer key technical properties, but also trigger severe immune-mediated diseases, such as celiac disease. We are currently witnessing a rise in the number of people adhering to gluten-free diets unwarranted by any medical need. In this dynamic context, this review aims to critically discuss the nutritional components of wheat, highlighting both the health benefits and wheat/gluten-related disorders, in order to address common misconceptions associated with wheat consumption.
