Abstract
BACKGROUND There is some evidence of a higher prevalence of coeliac disease (CD) among patients with SLE than in the general population. However, the prevalence estimates vary substantially. OBJECTIVE To investigate the prevalence of CD among patients with SLE through systematic review and meta-analysis. METHODS We performed searches in the databases of Medline, Embase, Cochrane and Web of Science Core Collection between 1 January 1990 and 9 July 2023. A total of 2053 publications were rendered in the searches, of which 68 were reviewed in full text and 14 included in the analyses. Primary analysis estimated the pooled prevalence of biopsy-verified CD in patients with SLE. In the secondary analysis, the prevalence of serological markers indicative of CD was investigated. The quality of studies was appraised using the Joanna Briggs Institute Critical Appraisal Tool. We conducted meta-regression analyses to investigate associations between the prevalence of CD in individuals with SLE and publication year, study population size, CD prevalence in the general population, proportion of females and quality assessment score. RESULTS A total of 14 studies met the inclusion criteria, of which 11 were included in the primary analysis of biopsy-verified CD. Among 1238 patients with SLE, 14 had CD. The weighted pooled prevalence of CD was 0.7% (95% CI 0.0 to 1.8). The weighted pooled prevalence of CD serological markers in 1063 patients with SLE was 3.7% (95% CI 1.4 to 6.7). In meta-regression analyses, no associations between CD prevalence and study characteristics, demographics and quality assessment scores were found. CONCLUSIONS In this meta-analysis, we found a weighted pooled prevalence of biopsy-verified CD in patients with SLE comparable with the prevalence in the general population. Our findings do not support routine screening for CD in patients with SLE. However, individual screening could be considered in cases of clinical suspicion and additional risk factors for CD.

Abstract
Introduction Celiac disease (CD) is an autoimmune disorder that is provoked by the consumption of gluten in genetically vulnerable individuals. CD affects individuals worldwide with an estimated prevalence of 1% and can manifest at any age. Growth retardation and anemia are common presentations in children with CD. The objective of this study is to estimate the prevalence of CD in multiple "at risk groups" and to characterize children with CD, presented to a tertiary hospital in Dubai, United Arab Emirates (UAE). Methods The study reviewed medical charts of all patients <18 years who had received serologic testing for CD. The study was conducted at Al Jalila Children's Specialty Hospital in Dubai, UAE, from January 2018 to July 2021. Extracted information from medical records included sociodemographics, laboratory findings, clinical presentation, and any associated co-morbidities. The European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) criteria were used to identify patients with CD. Results During the study period, 851 paediatric patients underwent serological screening for CD, out of which, 23 (2.7%) were confirmed with CD. Of the 23 patients diagnosed with CD, 43.5% had no gastrointestinal symptoms. Diabetes type 1 (30.4%) followed by iron deficiency anaemia (30%) and Hashimoto thyroiditis (9%) were the most commonly associated comorbidities. The prevalence of CD among paediatric patients with autoimmune thyroiditis (12.5%) was 1.92-times higher than that among paediatric patients with diabetes type 1 (6.5%). Conclusion The results of this study show that almost three out of every 100 paediatric patients who were screened for CD were confirmed to have the condition. These findings highlight the importance of screening children who are at risk or present symptoms suggestive of CD, to ensure early diagnosis and appropriate management.

Abstract
Proso millet is a nutritious, sustainable, and gluten free food which is currently underutilized. They can be incorporated into the grain industry and provide much needed healthy alternatives. Efficient grinding method should be adopted for easy incorporation. This study aimed to investigate the effect of three different methods of grinding namely, roller milling (RM), pin milling (PM), and hammer milling (HM) on proso millet flour rheology and baking properties for food application. The milling flow sheet was developed toward the production of the quality whole grain flour. The particle size distribution of all the flours showed bi-modal distribution except for the RM flour. The PM produced the flour with the finest particles with geometric mean diameter of 82 μm. The study also revealed that starch damage in the PM flour (4.64%) was higher than RM (2.46%) and HM flour (2.51%). The nutritional composition was not significantly affected by different grinding methods. Pasting properties of the flour were also affected by the grinding method applied. Rapid Visco Analysis profile showed pin mill flour to have a higher peak viscosity (PV) (2,295 cP) compared to HM (2,065 cP) and RM flour (2,130 cP). Finally, this study demonstrated that the production of bread from proso millet flour with desirable quality and texture is possible. The grinding method did not affect the specific volume of bread loaves and C-cell characteristics. The specific volume of the breads ranged from 2.40 to 2.52 cm3 /g. This study will help in promoting and producing value-added proso millet food products with enhanced nutritional quality.

Clin Rheumatol 2022; 41:977-990. [PMID: 35067768 DOI: 10.1007/s10067-021-06029-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 12/04/2021] [Accepted: 12/18/2021] [Indexed: 11/03/2022]
Abstract
Idiopathic pulmonary hemosiderosis (IPH) is a rare disease of unknown etiology. Due to the frequent findings of autoimmune antibodies - autoantibodies, immunologic causation of the diffuse alveolar hemorrhage in IPH has been proposed, to assess the prevalence/frequency and type of autoantibodies in pediatric patients with IPH. In addition, the patient demographics, diagnostic modalities used to diagnose IPH, treatment, and outcomes were also evaluated. Scoping review: The PubMed, Medline, and Embase databases were searched with appropriate MeSH terms to identify relevant papers consistent with the defined inclusion criteria. Thirteen observational studies comprising a total of 352 pediatric patients were included in this review. The majority of subjects were girls 217 out of 352 (61.6%). The mean and median ages of patients ranged from 3.1-6.5 years to 2.3-7 years, respectively. In the 10 studies that specified the number of patients in their cohorts with either at least one positive autoantibody or no antibody, the overall prevalence of autoantibodies was 76 out of 288 patients (26.4%). The prevalence of specific antibodies was as follows: ANA, 20.3%; ANCA, 17%; anti-dsDNA, 9.1%; RF, 12%; anti-SMA, 23.2%; and celiac antibodies, 25.9%. Cow's milk protein allergy was present in 16.2% of the children. The significance of an association between IPH and the presence of autoantibodies has not been clarified. The autoantibodies could be suggestive of an overall immune dysregulation rather than causation. However, limited evidence based on a single study suggests that the presence of ANA may be associated with a higher risk of recurrence and worse outcomes. Further research, including prospective studies, will be crucial to explore a possible genetic linkage between vasculitides, systemic rheumatologic diseases, and IPH.

Abstract
BACKGROUND Celiac disease (CD) is a common cause of malabsorption that is definitively diagnosed by abnormal bowel biopsy, symptoms and histologic changes to gluten free diet. The symptoms of irritable bowel syndrome (IBS) are common in our community as the majority of people in Guilan, north of Iran, consume rice daily. Also, a number of celiac patients are unknown, and IBS are mistakenly diagnosed. OBJECTIVE This study aimed to evaluate the prevalence of CD among IBS patients. METHODS A total of 475 consecutive patients with IBS, confirmed by Rome IV, underwent celiac serological tests antitissue transglutaminase antibodies (IgA-tTG, IgG-tTG) after obtaining a written consent form. In case of positive serological tests, biopsy was performed from small intestine after endoscopyRESULTS: Thirty-one (6.53%, 95% CI: 4.55-9.22) patients were positive for celiac serology. Based on Marsh-Oberhuber criteria, out of 9 patients with positive pathology 77.78% (95% CI: 40.19-96.05) had marsh IIIc. In IBS patients cramp (0.009) and stomach fullness (0.021) were two statistically significant IBS symptoms. CONCLUSIONS We suggest physicians to consider celiac examinations for all patients with IBS symptoms, even for patients with no obvious celiac symptoms.

Abstract
BACKGROUND Celiac disease (CD) is an immune-mediated disorder of the gut in which innate and adaptive responses are involved. Antimicrobial peptides (AMPs) constitute an arsenal of innate immunity regulators of paramount importance in the gut. However, the role of AMPs in CD is unclear. AIMS To evaluate the levels of fecal β-defensin-2, fecal calprotectin (FC), and antibodies against bactericidal/permeability-increasing protein (BPI) in the serum of children with active CD and to compare them with those of healthy controls (HCs). METHODS We examined 76 children with recently diagnosed CD between the age of 2-10 years (average age: 6.1 ± 1.2 years) and 32 HC (average age: 6.2 ± 3.8 years) in this study. We evaluated the level of fecal β-defensin-2 and FC levels in coprofiltrates, and the level of anti-BPI antibodies in blood serum. Correlation relationships between the parameters were assessed according to Pearson correlation coefficient. RESULTS Fecal β-defensin-2 concentration was greater in the CD group than in HC group, amounting to 99.6 ± 15.5 ng/mL and 64.0 ± 2.4 ng/mL, respectively (p < 0.02). The level of FC in the CD children was 35.4 ± 8.1 μg/g, while that in the control group was 19.1 ± 1.1 μg/g, (p < 0.05), representing a slightly increase. The concentration of anti-BPI antibodies in the CD and HC groups was 35.9 ± 10.1 U/mL and 5.2 ± 3.2 U/mL, respectively (p < 0.002). There was a strong and direct correlation between fecal β-defensin-2 and FC (r = 0.69), as well as a direct but weak relationship between fecal β-defensin-2 and anti-BPI antibodies (r = 0.35). CONCLUSIONS Our data reinforce that fecal β-defensin-2 and anti-BPI antibodies are greatly increased in patients with active CD. These biomarkers may be components of epithelial innate immunity in the intestine, with each having a distinct functional role in intestinal6 mucosal defense.

Abstract
BACKGROUND/AIMS Celiac disease (CD) is an autoimmune and genetic disease that is triggered by gluten intolerance. We aimed to investigate whether Celiac disease have any effect on Auditory Brainstem Response (ABR) waves compare to a healthy control group, and present its association with sensorineural hearing loss (SNHL). MATERIALS AND METHODS Thirty-eight patients aged 2 to 16 years old were included in the study. The patients had confirmed diagnosis of Celiac disease through duodenal biopsies and transglutaminase Antibody (Ab) (+). The control group consisted of 18 children aged 3 to 17 years old who were all admitted to the pediatric gastroenterology department due to complaints of constipation and transglutaminase Ab (-).All children underwent Auditory-Brain-Stem-Evoked Responses (ABR). The data were gathered using click stimulus at 10/s frequency 90dB HL. RESULTS The results of ABR examination did not show any difference between the patient group and control group as regards the latency of the waves I, III, V. No difference was observed between the two groups in the interpeak latecies I-III, I-V and III-V. None of the patients was observed to have clinical hearing loss. DISCUSSION The exact pathogenesis of neurological damages observed in Celiac disease is still unknown. Humoral immune mechanisms are the most frequently attributed cause. CONCLUSION Although no significant difference was found in hearing values between the study group and healthy control group, there is a need for further research on this subject.

Abstract
BACKGROUND Long-term outcomes and monitoring patterns in real-world practice are largely unknown among patients with celiac disease.
AIM To understand patterns of follow-up and management of patients with celiac disease, and to characterize symptoms and villous atrophy after diagnosis.
METHODS A retrospective chart review study was performed using medical chart data of patients diagnosed with celiac disease. Three gastroenterology referral centers, with substantial expertise in celiac disease, participated in the United Kingdom, United States, and Norway. Demographic and clinical data were collected from medical charts. Descriptive analyses were conducted on patients with biopsy-confirmed celiac disease, diagnosed between 2008 and 2012, with at least one follow-up visit before December 31, 2017. Patient demographic and clinical characteristics, biopsy/serology tests and results, symptoms, and comorbidities were captured at diagnosis and for each clinic visit occurring within the study period (i.e., before the study end date of December 31, 2017).
RESULTS A total of 300 patients were included in this study [72% female; mean age at diagnosis: 38.9 years, standard deviation (SD) 17.2]. Patients were followed-up for a mean of 29.9 mo (SD 22.1) and there were, on average, three follow-up visits per patient during the study period. Over two-thirds (68.4%) of patients were recorded as having ongoing gastrointestinal symptoms and 11.0% had ongoing symptoms and enteropathy during follow-up. Approximately 80% of patients were referred to a dietician at least once during the follow-up period. Half (50.0%) of the patients underwent at least one follow-up duodenal biopsy and 36.6% had continued villous atrophy. Patterns of monitoring varied between sites. Biopsies were conducted more frequently in Norway and patients in the United States had a longer follow-up duration.
CONCLUSION This real-world study demonstrates variable follow-up of patients with celiac disease despite most patients continuing to have abnormal histology and symptoms after diagnosis.

Abstract
Drinks are important in the human diet. The most promising ones include fermented beverages enriched with bioactive substances of their raw materials and with products of their fermentation. Gluten-free foods, too, are becoming popular as there are more and more people worldwide suffering from coeliac disease. The paper presents the results of theoretical and experimental research on developing a technology of a fermented soft drink based on rice as a gluten-free raw material. The domestic cultivars of husked and unhusked rice described in the paper are Agat, Prestizh, and Premium. Their physical, biological, and physicochemical parameters have been studied, and their amino acid and vitamin composition, the content of macronutrients and trace elements have been determined. According to the research results, it is practical to use rice of the Agat variety in the technology of fermented beverages. Compared with the samples of Premium and Prestizh, the extractivity of Agat is higher by 2–5%, and as to the soundness of its kernels and the husk content, it exceeds them, respectively, by 2.5 and 5.5%. The fat content, which reduces the amount of esters formed during fermentation and adversely affects the foam retention of a drink, was lower in Agat by 28–37%. The content of protein compounds, vitamins, macronutrients and trace elements in grain is essential for the technology of fermented beverages. It has been established that Agat is higher in amino acids than other varieties are: by 5.7% (husked) and by 18% (unhusked). The highest content of vitamins has been found in Agat rice (on average, by 9.4% more of them). Compared with the other cultivars, unhusked Agat rice is higher in the macronutrients and trace elements that are vital for yeast activity: calcium – by 28%, magnesium – by 24%, iron – by 10–18%, copper – by 16.6%. The optimal initial concentration of yeast cells in the wort is 3–5 million/cm3. When using husked rice, the acidity of the wort at the end of fermentation was higher by 7.6% than it was in the wort made with unhusked rice. When comparing different varieties of rice, the acidity values of the fermented wort did not differ significantly. All samples had high sensory qualities characteristic of fermented beverages.

Abstract
The incidence of celiac disease has been increasing in recent years. Celiac disease is an autoimmune enteropathy that emerges mostly in the childhood period. This disorder is a chronic condition of the small intestine due to gluten intake in individuals with genetic predisposition. In the treatment of celiac disease, gluten-free diet therapy is applied. However, the adaptation process to the diet may create difficulties for patients. Compliance with diet is much more difficult among patients with celiac disease in childhood and adolescence than in adult patients. Children and adolescents face distinct difficulties in their homes, at school, and in their social lives. Besides following dietary treatment, children and adolescents living with celiac disease need peer support to manage their daily routines. In this article, we aimed to discuss the problems experienced by children and adolescents living with celiac disease and nursing approaches to these problems.

Abstract
Celiac disease (CD) is a chronic intestinal immune-mediated disease occurring in genetically susceptible individuals who are exposed to gluten. Although it primarily affects the small intestine, CD has been associated with a wide spectrum of extraintestinal manifestations, including thromboembolism and cardiovascular events. The risk of ischemic stroke, myocardial infarction, and thromboembolism, such as deep vein thrombosis and pulmonary embolism, is higher in patients with CD, while there is accumulating evidence that gluten-free diet in CD patients decreases the risk of these complications. The pathogenetic mechanism of increasing hypercoagulability in CD is multifactorial and involves hyperhomocysteinemia due to malabsorption of vitamins B12, B6, and folic acid; endothelial dysfunction; acceleration of atherosclerosis; chronic inflammation; thrombocytosis; and thrombophilia. Therefore, in cases of thromboembolic complications and cardiovascular disease of obscure etiology, clinicians' awareness of possible celiac disease is warranted.

Abstract
Gluten-related neurological disorders (GRND) represent a spectrum of neurological manifestations that are triggered by gluten. In coeliac disease, a T-cell mediated enteropathy is triggered by gluten in genetically predisposed individuals. The underlying pathological mechanism of the neurological dysfunction is not yet clear. The aim of this review is to collate existing neuropathological findings in GRND as a means of aiding the understanding of the pathophysiology. A systematic search of the Pubmed Database yielded 188 articles, of which 32 were included, containing 98 eligible cases with a description of pathological findings in GRND. In gluten ataxia, loss of Purkinje cells, atrophy, gliosis and astrocytosis were apparent, as well as diffuse lymphocytic infiltration and perivascular cuffing with lymphocytes. In patients with large-fiber neuropathy, nerve biopsies revealed axonopathy, loss of myelinated fibers and focal and perivascular infiltration by inflammatory cells. Inflammatory infiltrate was also observed in muscle in myopathy and in cerebrum of patients with encephalopathy and patients with epilepsy. Such changes were not seen in skin biopsies from patients with small fiber neuropathies. The findings from this systematic review suggest an immune mediated pathogenesis for GRND. Future research should focus on the characterization of the inflammatory cell infiltrates and identifying target epitopes.

Abstract
The article is devoted to the study of the influence of hydrocolloids and animal protein concentrates on the formation of the foam-like structure of gluten-free non-yeast dough as the main factor for bread quality formation. The use of CMC in a concentration of 0.5% is found to be appropriate. The bread volume increases to 236 cm3.100g-1 in comparison with the control sample in water – 202 cm3.100g-1. It is proved that the suggested additives in the amounts of 0.5 ‒ 1.0% Helios-11 and 0.5% CMC solution cause 100% resistance of egg white foam. In this case, the foaming ability increases with the addition of Helios-11 only in amounts up to 1.0%, then decreases for higher amounts of Helios-11 or in the presence of CMC. This can be explained by the increase in density of the whipping mass and the ability of both additives to thicken solutions. In the presence of the additives, the foamy texture of the dough changes. The number of large pores (0.7 – 1.5 mm) decreases almost fourfold, and the number of small and very small pores (0.1 ‒ 0.5 mm) increases significantly. The index of form resistance of the control sample is 32, and in the presence of 0.5% CMC with 0.5 ‒ 1.0% APC is 20 ‒ 21, which indicates a decrease in the surface tension of the aqueous solutions with additives, to a large extent, in the case of joint use.

Abstract
Celiac disease (CD) is an immune-mediated gastrointestinal disorder driven by innate and adaptive immune responses to gluten. Patients with CD are at an increased risk of several neurological manifestations, frequently peripheral neuropathy and gluten ataxia. A systematic literature review of the most commonly reported neurological manifestations (neuropathy and ataxia) associated with CD was performed. MEDLINE, Embase, the Cochrane Library, and conference proceedings were systematically searched from January 2007 through September 2018. Included studies evaluated patients with CD with at least one neurological manifestation of interest and reported prevalence, and/or incidence, and/or clinical outcomes. Sixteen studies were included describing the risk of gluten neuropathy and/or gluten ataxia in patients with CD. Gluten neuropathy was a neurological manifestation in CD (up to 39%) in 13 studies. Nine studies reported a lower risk and/or prevalence of gluten ataxia with a range of 0%⁻6%. Adherence to a gluten-free diet appeared to improve symptoms of both neuropathy and ataxia. The prevalence of gluten neuropathy and gluten ataxia in patients with CD varied in reported studies, but the increased risk supports the need for physicians to consider CD in patients with ataxia and neurological manifestations of unknown etiology.

Abstract
GOAL The goal of this study is to determine factors associated with performance of duodenal biopsy during upper endoscopy. BACKGROUND Celiac disease (CD) prevalence approaches 1% in the United States and Europe, yet CD remains underdiagnosed, in part because of low rates of duodenal biopsy during upper endoscopy. We aimed to identify patient and provider factors associated with performance of duodenal biopsy during upper endoscopy. STUDY In our hospital-based endoscopy suite, we identified all patients not previously diagnosed with CD who underwent upper endoscopy during a 5-year period for one of the following indications: abdominal pain/dyspepsia, gastroesophageal reflux (GERD), anemia/iron deficiency, diarrhea, and weight loss. We employed univariate and multivariate analysis to determine the association between clinical factors and the performance of duodenal biopsy. RESULTS Of 8572 patients included in the study, 4863 (57%) underwent duodenal biopsy. Of those who underwent duodenal biopsy, 24 (0.49%) were found to have CD. On multivariate analysis, age, gender, indication, gross endoscopic appearance, physician affiliation with a celiac disease center, and absence of a participating trainee were all significantly associated with the performance of duodenal biopsy. There was wide variability among providers, with duodenal biopsy rates ranging from 27% to 91% during these procedures. CONCLUSIONS A duodenal biopsy is more likely to be performed in younger patients, females, and for key indications such as weight loss, diarrhea, and anemia. Providers varied widely in the performance of duodenal biopsy. Further study is warranted to better understand the decision to perform duodenal biopsy and to determine the optimal scenarios for its performance.

Abstract
Historically, a gluten-free diet was recommended only for those with celiac disease or IgE-mediated wheat allergy. With changes in food allergy labeling in the United States and the publication of several best-selling books, gluten-related disorders have come to the forefront of popular culture. As a result, there has been a dramatic increase in the number of gluten-free diet followers, many for nontraditional reasons. As "going gluten-free" has become mainstream, it is imperative that health care providers acquire the knowledge to identify true gluten-related disorders to effectively counsel their patients and minimize potential complications from following such a restrictive diet.

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

Abstract
Celiac disease (CD) is known to be more prevalent in first-degree relatives of patients. In this retrospective cohort study of 609 relatives between 1994 and 2016, we investigated the effect of sex, HLA type, and age at time of index celiac diagnosis. Pearson's chi-square test and Kaplan-Meier survival analysis were used as statistical analyses. CD screening was carried out for 427 relatives (70%), resulting in a prevalence of 15%. HLA typing in 335 relatives showed HLA-DQ2/DQ8 positivity in 87.5%. In 63% of children and all parents, celiac disease was diagnosed at first screening. It was diagnosed significantly more often in females, HLA-DQ2 homozygosity, and children (all p < 0.05). In children aged 0-1 year at time of index diagnosis, celiac disease was diagnosed after consecutive screening in 58%, after 3.9 ± 2.5 (max 10) years (p < 0.001).Conclusion: Future screening policies for relatives of celiac patients should include retesting, especially in HLA-positive relatives younger than 10 years of age. In addition, one-time celiac-specific antibody testing alone could be sufficient to rule out the disease in adolescent siblings and parents of newly diagnosed celiac patients. What is Known: • Celiac disease is more prevalent in first-degree relatives of celiac patients (risk 3-12%). • HLA-DQ2 homozygous sisters/daughters are at highest risk (25%). What is New: • If younger than 10 years of age, repeated testing is necessary in HLA-DQ2/DQ8-positive first-degree relatives when celiac disease is diagnosed in a family. • One-time celiac-specific antibody testing alone could be sufficient to rule out the disease in adolescent siblings and parents of newly diagnosed celiac patients.

Abstract
Celiac disease is an autoimmune disorder in which the lining of the gastrointestinal tract is damaged by an immune-mediated response to gluten proteins (Allen, 2015). It is a polygenetic disease that only appears in genetically susceptible individuals (Newton & Singer, 2012). It is a worldwide concern, with North America having a high prevalence rate (Liu et al., 2017). Celiac disease can present in a spectrum of manifestations, making it difficult to identify and diagnosis (Reilly & Green, 2012). High-risk populations include those with a positive family history as well as individuals with other autoimmune disorders (Newton & Singer, 2012). Screening and diagnosis are completed with a blood test followed by a biopsy of the small intestinal lining (Zevit & Shamir, 2014). Currently, the only treatment for celiac disease is a strict, gluten-free diet. Further research is warranted in areas of environmental risk factors and treatments (Allen, 2015; Newton & Singer, 2012).

Abstract
BACKGROUND Familial Mediterranean fever and celiac disease share some common clinical features such as abdominal pain, diarrhea, arthralgia and arthritis. Also, both of the diseases are associated with many inflammatory and autoimmune diseases. Previous studies have shown the association between familial Mediterranean fever (FMF) and different clinical conditions. OBJECTIVE We aimed to investigate the relationship between celiac disease and colchicine-resistant familial Mediterranean fever (crFMF) disease. METHODS This prospective study was conducted at the Department of Pediatric Gastroenterology and Pediatric Rheumatology from October 2015 to August 2016. A total of 24 patients with crFMF were included in the study. We used 60 sex- and age-matched healthy subjects as a control group. Levels of total IgA and tissue transglutaminase (tTG) IgA antibody were measured in both groups. Those with increased level of tTG IgA were tested for anti-endomysium IgA antibodies (EMA). Gastroduodenoscopy and intestinal biopsy were planned for a definite diagnosis of celiac disease in patients with positive EMA. RESULTS Of the 24 patients in this study, 18 (75.0%) were female. Only 4 (16.6%) of 24 patients were positive for tTG IgA. Patients with positive tTG IgA were then tested for EMA IgA antibodies and none of them had a positive result. Only one (1.6%) subject from the control group was positive for tTG IgA but EMA positivity was not detected. CONCLUSION We did not found celiac disease in 24 children with crFMF. Since crFMF disease is rarely seen in general population, further studies with more patients are needed to provide more precise interpretation.

Abstract
Food allergies present numerous challenges to coping in everyday life. Even simple things like planning a lunch with a friend can be stressful for people with food allergies. But are some people more adversely impacted by having a food allergy than other people? This paper addressed this question by investigating whether individual differences in the Big Five personality traits (neuroticism, extraversion, openness, agreeableness, and conscientiousness) are related to food allergy-related problems in everyday life among adults with food allergies. Participants were 108 adults (85% female; mean age = 40.2; age range 18–87) with a physician-diagnosed food allergy [most commonly to gluten (54.6%), peanuts (21.3%), cow's milk (16.7%), and shellfish/seafood (16.7%)]. Participants completed an initial online survey that measured demographics, food allergy information, and personality traits using the Big Five Inventory (John et al., 1991). For 2 weeks, participants completed a daily online survey that queried the occurrence of 25 food allergy issues that day and participants' overall stress and mood that day. Neuroticism did not predict more frequent allergy issues or greater stress/poorer mood on days with more allergy issues. Instead, higher openness to experience predicted a range of issues including going hungry because there is no safe food available, problems finding suitable foods when grocery shopping, feeling anxious at social occasions involving food, being excluded, and feeling embarrassed and poorly understood about their food allergy. Conscientious people were less embarrassed or self-conscious about their food allergy, but they had more problems eating out, and their positive mood was more impaired by allergy issues than their less conscientious peers. Extraversion and agreeableness played minor roles. Personality testing can identify people that may have difficulty living with food allergies–such as those higher in openness to experience.

Abstract
BACKGROUND Celiac disease is a chronic autoimmune enteropathy caused by gluten ingestion. While its prevalence in Western countries is reported to be as high as 1%, the prevalence has not been evaluated in a large-scale study of a Japanese population. The aim of our study was to clarify the possible presence of celiac disease in a Japanese non-clinical population as well as in patients showing symptoms suggestive of the disease. METHODS Serum samples were collected from 2008 non-clinical adults and 47 patients with chronic unexplained abdominal symptoms between April 2014 and June 2016. The anti-tissue transglutaminase (TTG) immunoglobulin A antibody titer was determined as a screening test for celiac disease in all subjects, and individuals with a value of >2 U/mL subsequently underwent testing for the presence of serum endomysial IgA antibody (EMA) as confirmation. Those testing positive for EMA or with a high concentration (>10 U/mL) of TTG were further investigated by histopathological examinations of duodenal mucosal biopsy specimens and HLA typing tests. RESULTS Of the 2008 non-clinical adults from whom serum samples were collected, 161 tested positive for TTG, and all tested negative for EMA. Four subjects who had a high TTG titer were invited to undergo confirmatory testing, and the histopathological results confirmed the presence of celiac disease in only a single case (0.05%). Of the 47 symptomatic patients, one (2.1%) was found to have a high TTG titer and was diagnosed with celiac disease based on duodenal histopathological findings. CONCLUSION The presence of celiac disease in a non-clinical Japanese population was low at 0.05% and was rarely found in patients with unexplained chronic abdominal symptoms.

Abstract
BACKGROUND AND STUDY AIMS Many people with celiac disease are undiagnosed and there is evidence that insufficient duodenal samples may contribute to underdiagnosis. The aims of this study were to investigate whether more samples leads to a greater likelihood of a diagnosis of celiac disease and to elucidate factors that influence the number of samples collected. PATIENTS AND METHODS We identified patients from two community hospitals who were undergoing duodenal biopsy for indications (as identified by International Classification of Diseases code) compatible with possible celiac disease. Three cohorts were evaluated: no celiac disease (NCD, normal villi), celiac disease (villous atrophy, Marsh score 3), and possible celiac disease (PCD, Marsh score < 3). Endoscopic features, indication, setting, trainee presence, and patient demographic details were evaluated for their role in sample collection. RESULTS 5997 patients met the inclusion criteria. Patients with a final diagnosis of celiac disease had a median of 4 specimens collected. The percentage of patients diagnosed with celiac disease with one sample was 0.3 % compared with 12.8 % of those with six samples ( P = 0.001). Patient factors that positively correlated with the number of samples collected were endoscopic features, demographic details, and indication ( P = 0.001). Endoscopist factors that positively correlated with the number of samples collected were absence of a trainee, pediatric gastroenterologist, and outpatient setting ( P < 0.001). CONCLUSIONS Histological diagnosis of celiac disease significantly increased with six samples. Multiple factors influenced whether adequate biopsies were taken. Adherence to guidelines may increase the diagnosis rate of celiac disease.

Abstract
Although many people have symptoms of celiac disease, it can take a while to diagnose. Villous atrophy may be present long before any gastrointestinal symptoms. An important point to acknowledge is that celiac disease could be identified earlier in some women with a positive family history. The disease also could be the cause of some women's reproductive problems. Primary care providers, using comprehensive history taking, are in the unique position to identify individuals who may have celiac disease, assist women in gaining knowledge about a gluten-free diet, order diagnostic testing, and refer to a gastroenterologist. The positive change in fertility with a simultaneous improvement of nutrient deficiencies shortly after adopting a gluten-free diet indicates a possible link between such nutrients and sex hormone function. High levels of homocysteine, which can negatively impact fertility, have also been linked to individuals with problems, such as celiac disease, that decrease vitamin B12 absorption. The purpose of this article is to review the literature and the evidence-based care guidelines for comprehensive screening, diagnostics, and pathophysiology of celiac disease, with a specific focus on the female reproductive system, anemia management, and gluten-free diet integration.

Abstract
BACKGROUND & AIMS Celiac disease is an immune-mediated enteropathy characterized with high heterogeneity in presentation among genetically predisposed individuals. In recent years, a change in the phenotypic presentation of celiac disease has been reported. We studied clinical presentation, from 1960 through 2015, in Ireland, which has a high incidence of celiac disease. METHODS We performed a retrospective analysis of medical charts from patients diagnosed with celiac disease at 5 secondary referral centers in Ireland from 1960 through 2015 (n = 749; median age, 56 years; age range, 18-91 years). The cohort was divided into 5 groups based on year of diagnosis (≤1985, 1986-1995, 1996-2005, 2006-2010, or 2011 and later). We collected findings from clinical presentation at diagnosis; serology tests; small intestinal biopsy analyses; and patients' demographic, clinical, and family data. Presentations at diagnosis were classified according to the Oslo criteria as follows: classical (patients presenting with malabsorption), nonclassical (no signs or symptoms of malabsorption at presentation), or subclinical (below the threshold of clinical detection). The primary outcome was change in clinical presentation of celiac disease over time. RESULTS Of the 749 patients studied, 512 were female and 237 were male (ratio of 2.2:1). Female patients were diagnosed at younger ages than male patients (42 vs 47 years, respectively; P = .004), and had more immune-mediated conditions than male patients (35.7% for female patients vs 21.5% for male patients; P < .001). For patients diagnosed as adults (after the age of 18 years), the median age of diagnosis increased from 34.0 years during the period ≤1985 to median ages of 44-46 years after 1985 (P < .002). A smaller proportion of patients presented with classical features of celiac disease after 2010 (48.4%) than ≤1985 (85.2%); the proportion of patients with nonclassical or subclinical celiac disease increased from 14.8% ≤1985 to 51.6% after 2010 (P = .006 for each). Biopsies categorized as Marsh 3c decreased, from 52.2% in the period 1996-2005 to 22.5% in the period after 2010 (P = .003). The prevalence of associated thyroid disease has decreased during the study period, from 36.6% ≤1985 to 17.1% after 2010 (P = .039), whereas body mass index at diagnosis increased from 21.5 kg/m2 ≤1985 to 24.8 kg/m2 after 2010 (P < .001). CONCLUSIONS We found the clinical presentation of celiac disease changed significantly in Ireland from 1960 through 2015. The age of presentation in adulthood increased over this time period, as did the proportions of patients with nonclassical or subclinical disease.

Abstract
BACKGROUND Newborns at high risk of celiac disease (CD) were recruited in Italy in the context of the PreventCD study and closely monitored for CD, from 4 months up to a mean age of 8 years at follow-up. The aim of our study was to investigate intestinal T-cell reactivity to gliadin at the first clinical and/or serological signs of CD. METHODS Gliadin-reactive T-cell lines were generated from intestinal biopsies of 19 HLA-DQ2-or HLA-DQ8-positive children. At biopsy, 11 children had a diagnosis of acute CD, two of potential CD, and six were non-celiac controls. Immune reactivity was evaluated against gliadin and known immunogenic peptides from α-, γ-, or ω-gliadins. The role of deamidation by transglutaminase (tTG) in determining the immunogenicity of gliadin was also investigated. RESULTS Most of the children with CD (either acute or potential) had an inflammatory response to gliadin. Notably, signs of T-cell reactivity to gliadin were also found in some non-celiac subjects, in which IFN-γ responses occurred mainly when regulatory IL-10 and TGF-β cytokines were blocked. Interestingly, PreventCD children reacted to gliadin peptides found active in adult CD patients, and tTG deamidation markedly enhanced gliadin recognition. CONCLUSIONS T cells reactive to gliadin can be detected in the intestine of children at high risk of developing CD, in some cases also in the presence of a normal mucosa and negative CD-associated antibodies. Furthermore, children at a very early stage of CD recognize the same gliadin epitopes that are active in adult CD patients. Tissue transglutaminase strongly enhances gluten T-cell immunogenicity in early CD.

Abstract
Celiac disease is induced by the consumption of gluten containing cereals (wheat, spelt, barley, rye). With a prevalence of ~ 1 %, it is the most common non-infectious chronic inflammatory intestinal disease worldwide. It manifests in all age groups, either classically with abdominal pain, diarrhoea and growth failure or weight loss, more commonly with indirect consequences of malabsorption, such as anaemia and osteoporosis, or with associated autoimmune diseases like type 1 diabetes, autoimmune thyroiditis or dermatitis herpetiformis. The pathogenesis of celiac disease is well explored. Gluten, the cereal storage protein, is not completely digested and reaches the intestinal mucosa where it activates inflammatory T cells, which cause atrophy of the resorptive villi. This T‑cell activation requires a genetic predisposition (the molecules HLA-DQ2 or -DQ8 on antigen-presenting immune cells). Moreover, the enzyme tissue transglutaminase (TG2) which is released in the mucosa increases the immunogenicity of the gluten peptides by a deamidation reaction. The test for serum antibodies to the autoantigen TG2 is one of the best diagnostic markers in medicine, which in combination with endoscopically obtained biopsies, secures the diagnosis of celiac disease. Despite these tools celiac disease is severely underdiagnosed, with 80-90 % of those affected being undetected. The untreated condition can lead to grave complications. These include the consequences of malabsorption, cancers (especially intestinal T‑cell lymphoma), and likely also the promotion of autoimmune diseases. The therapy of celiac disease, a strict gluten-free diet, is difficult to maintain and not always effective. Alternative, supporting pharmacological therapies are urgently needed and are currently in development.

Abstract
Gluten derived from wheat and related triticeae cereals possesses distinct amino acid sequences that provoke the immunopathogenic features of celiac disease (CD) in genetically susceptible individuals. However, the role of oat-derived gluten, or avenins, in CD pathogenesis remains a disputed matter, as evidenced by a lack in harmonized legislation regarding gluten classification in relation to gluten-free labeling. In this study, we have analyzed a panel of pure oat cultivars using a sandwich ELISA based on the R5 monoclonal antibody (mAb), which binds to canonical epitopes occurring within celiagenic peptides present in triticeae-derived gluten but reportedly not present in avenins. We have identified three varieties of oats that reproducibly bind R5 antibodies and levels indicating the presence of gluten at more than the 20 ppm gluten regulatory threshold. Nested assessment using Western blot analysis and alternative gluten detection systems corroborated these results. Collectively, these data suggest that select oat varieties may prove problematic to patients with CD and to food companies and regulatory agencies and will extend our basic understanding of current gluten detection systems.

Abstract
We aimed to assess the frequency of celiac disease (CD) in patients with Familial Mediterranean Fever (FMF). This prospective study was carried out from October 2015 to March 2016 and included 303 patients with FMF. We used 98 sex- and age-matched healthy subjects as a control group. Levels of total IgA and tissue transglutaminase (tTG) IgA antibody were measured in all groups. Those with increased level of tTG IgA were tested for anti-endomysium IgA antibodies (EMA). Patients with positive EMA underwent gastro-duodenoscopy and intestinal biopsy for a definite diagnosis of CD. Only 9 of 303 patients (2.9%) were positive for tTG IgA. Patients positive for tTG IgA were then tested for EMA and only one of them (0.3%) had a positive result. This patient underwent gastro-duodenoscopy. The pathological report was compatible with Marsh 0 classification score for the diagnosis of CD. Two subjects from the control group were positive for tTG IgA but none of them had positive EMA antibodies. We did not find CD in the large cohort of childhood FMF patients. The prevalence of CD did not show association with presence of childhood FMF in this study and CD would not be a considerable complication of childhood FMF.

Abstract
ABSTRACT Objective: To investigate the nutritional status variation and symptomatology of patients with celiac disease and non-celiac gluten sensitivity after specialized dietary advice Methods: This prospective study included 80 patients with celiac disease and non-celiac gluten sensitivity. Clinical, metabolic, and nutritional variables were collected from medical records, and the symptomatology was investigated by the Metabolic Screening Questionnaire. The variables were assessed on two occasions (T1 - before dietary advice and T2 - after dietary advice) with an interval of three months between T1 and T2 Results: The median age was 42 years. The prevalences of celiac disease and non-celiac gluten sensitivity were 66.2% and 33.8%, respectively. Normal weight prevailed at T1 (58.8%) and T2 (56.3%), but 30.0% of the patients at T1 and 34.9% of the patients at T2 had excess weight. The two conditions had similar symptomatology. The most frequent signs and symptoms on both occasions involved the gastrointestinal tract, followed by energy/activity and emotions. All symptoms decreased significantly after the introduction of a proper diet Conclusion: The patients were normal weight on both study occasions (T1 and T2), and the symptoms improved after dietary advice. Thus, we reinforce the importance of proper dietary management in both clinical conditions to make dietary adjustments that improve these individuals' symptomatology.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccines are currently utilised globally in national immunisation programmes. While evidence from clinical trials and epidemiological studies suggest that the HPV vaccines are both effective and safe, concerns about the safety of the vaccine and scientifically unproven associations with severe adverse events following immunisation have led to dramatic decreases in vaccine uptake in Japan and acceptance issues in other countries. AIM In Scotland, we utilised hospital admissions data to assess the impact of the HPV immunisation programme on the incidence of 60 diagnoses between 2004 and 2014 in both girls and boys; with boys acting as a comparator group. METHODS Tabular and graphical outputs of the number of admissions, the incidence and the incidence ratio of 59 diagnoses were created to assess trends before and after the introduction of the HPV vaccine. Data linkage was utilised to investigate further the increase in Bell palsy diagnoses. RESULTS Fifty-four diagnoses showed no change in incidence following the introduction of the national immunisation programme, and while small increases in incidence were observed for Bell palsy, coeliac disease, ovarian dysfunction, juvenile onset of type 1 diabetes, demyelinating disease and juvenile rheumatoid arthritis, none was statistically significant. CONCLUSIONS Consistent with previous evidence, we present disaggregate data that reiterate the safety of both HPV vaccines.

[PMID: 26356552 DOI: 10.3238/arztebl.2015.0553] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 04/28/2014] [Revised: 07/02/2015] [Accepted: 07/02/2015] [Indexed: 12/19/2022]
Abstract
BACKGROUND Untreated celiac disease is associated with increased morbidity and mortality. Until now, no up-to-date figures have been available on the prevalence of celiac disease among children and adolescents in Germany, or on the percentage of undiagnosed cases. METHODS To estimate the prevalence of celiac disease, serum samples obtained from 2003 to 2006 from participants in the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) were studied for celiac disease-specific autoantibodies and total IgA. RESULTS Of the 12 741 study participants aged 1 to 17 years (6546 boys, 6195 girls), 9 (0.07%) had a reported history of celiac disease. An elevated concentration of serum autoantibodies to tissue transglutaminase was found in 91 children with a normal IgA concentration and in 7 with IgA deficiency. The prevalence of undiagnosed celiac disease, based on positive autoantibody findings, was 0.8% (95% confidence interval 0.6-1.0%), and the overall prevalence of the disease was 0.9%. Seropositive children and adolescents had lower ferritin and red blood cell folate concentrations than seronegative ones; they also tended to be shorter and to weigh less as reflected by age- and sex-standardized z-scores. CONCLUSION The 0.9% prevalence of celiac disease in Germany, as determined from a combination of serological findings and clinical histories, is similar to reported prevalences elsewhere in Europe and North America. Pediatricians, primary care physicians, internists, and other specialists should be aware of the broad spectrum of clinical manifestations of this disease. Children who have symptoms suggestive of celiac disease or belong to a group at risk for it should be tested for antibodies against tissue transglutaminase, as should symptomatic adults after the exclusion of other possible causes. It is not yet clear whether asymptomatic adults from high-risk groups should be tested.

Celiac disease diagnosis still significantly delayed - Doctor's but not patients' delay responsive for the increased total delay in women. Dig Liver Dis 2016; 48:1148-54. [PMID: 27401607 DOI: 10.1016/j.dld.2016.06.016] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2016] [Revised: 06/02/2016] [Accepted: 06/10/2016] [Indexed: 12/11/2022]
Abstract
BACKGROUND There is insufficient data on diagnostic delay and associated factors in celiac disease (CeD) as well as on its potential impact on the course of disease. METHODS Specifically taking its two components - patients' and doctors' delay - into account, we performed a large systematic patient survey study among unselected CeD patients in Switzerland. RESULTS We found a mean/median total diagnostic delay of 87/24 months (IQR 5-96), with a range from 0 up to 780 months and roughly equal fractions of patients' and doctors' delay. Both mean/median total (93.1/24 vs. 60.2/12, p<0.001) and doctors' (41.8/3 vs. 23.9/2, p<0.001) diagnostic delay were significantly higher in female vs. male patients, whereas patients' delay was similar, regardless of preceding irritable bowel syndrome diagnosis. Patients with a diagnostic delay shorter than 2 years were significantly less often in need of steroids and/or immunosuppressants, substitution for any nutritional deficiency but more often free of symptoms 6 and 12 months after diagnosis. CONCLUSIONS There is a substantial diagnostic delay in CeD, which is associated with a worse clinical outcome and significantly longer in female patients. This increased diagnostic delay in women is due to doctors' but not patients' delay and cannot be explained by antecedent IBS prior to establishing the CeD diagnosis.

Adult Celiac Disease: Patients Are Shorter Compared with Their Peers in the General Population. Middle East J Dig Dis 2016; 8:303-309.

Abstract
BACKGROUND Delay in diagnosis of celiac disease (CD) occurs frequently, although its consequences are mostly not known. One of the presented symptoms in pediatric patients with CD is the short stature. However, far too little attention has been paid to physical features including height of adult patients with CD. This study was undertaken to evaluate whether patients suffering from CD are shorter in comparison with the general population without CD. As well, we evaluated probable correlations between demographic and physical features, main complains, serum anti tTG level, and intestinal pathology damage between short (lower quartile) versus tall stature (upper quartile) patients with CD. METHODS This was a retrospective cross-sectional study on 219 adult patients diagnosed as having CD in the Celiac Disease Center, between June 2008 and June 2014 in Mashhad, Iran. The exclusion criteria were ages less than 18 and more than 60 years. Height was compared with a group of 657 age- and sex matched control cases from the healthy population. The probable influencing factors on height such as intestinal pathology, serum level of anti-tissue transglutaminase(anti-tTG), serum vitamin D, and hemoglobin level at the time of diagnosis were assessed and were compared in short (lower quartile) versus tall stature (upper quartile) patients with CD. RESULTS Both male (n=65) and female (n=154) patients with CD were shorter than their counterpart in the general population (males: 168.5±8.6 to 171.3±7.2cm, p <0.01 and females: 154.8±10.58 to 157.8±7.2 cm, p <0.01). Spearman linear correlation showed height in patient with CD was correlated with serum hemoglobin (p <0.001, r=0.285) and bone mineral density (p<0.001) and not with serum vitamin D levels (p =0.024, r=0.237), but was not correlated with anti-tTG serum levels (p=0.97). CD patients with upper and lower quartile of height in men and women had no significant difference in the anti-tTG level and degree of duodenal pathology(Marsh grade). Anemia as main complaint was more prevalent in shorter versus taller men. CONCLUSION Adults with CD are shorter compared with healthy adults. There is a direct correlation between height and anemia and bone mineral density. This finding highlights the importance of early detection and treatment of CD.

Abstract
OBJECTIVE Type 1 diabetes (T1D) or celiac disease (CD) develops in at least 2% of the general population. Early detection of disease-specific autoimmunity and subsequent monitoring would be possible if screening tests were more widely available. Currently, screening for islet autoimmunity is available only in a research setting, and CD-specific autoimmunity screening is limited to those in high-risk groups. This study assessed the feasibility of incorporating T1D and CD autoantibody screening into a pediatric practice. METHODS Patient engagement strategies, blood collection preference, blood sample volume, rate of autoantibody detection in the general population, and parental satisfaction were assessed. Over 5 weeks, research staff recruited 200 patients, aged 2-6 yr from two pediatric practices in the Denver area to be screened for islet autoantibodies (IAs) and the transglutaminase antibody. RESULTS Of the 765 parents approached, 200 (26%) completed the same-day screening. Of the 565 subjects who did not complete the screening, 345 expressed interest, but were unable to make a participation decision. A finger stick, compared with a venous draw, was the preferred method of sample collection. Both methods yielded sufficient blood volume for autoantibody determination. IAs or the transglutaminase antibody were detected in 11 subjects. Parents expressed satisfaction with all aspects of participation. CONCLUSIONS The results of this study suggest that it is feasible to conduct this type of screening in a pediatric clinic. Such screening could lead to increased disease awareness and the possible benefits that can result from early detection.

Abstract
Gluten derived from wheat and related Triticeae can induce gluten sensitivity as well as celiac disease. Consequently, gluten content in foods labeled "gluten-free" is regulated. Determination of potential contamination in such foods is achieved using immunoassays based on monoclonal antibodies (mAbs) that recognize specific epitopes present in gluten. However, food-processing measures can affect epitope recognition. In particular, preparation of wheat protein isolate through deamidation of glutamine residues significantly limits the ability of commercial gluten testing kits in their ability to recognize gluten. Adding to this concern, evidence suggests that deamidated gluten imparts more pathogenic potential in celiac disease than native gluten. To address the heightened need for antibody-based tools that can recognize deamidated gluten, we have generated a novel mAb, 2B9, and subsequently developed it as a rapid lateral flow immunoassay. Herein, we report the ability of the 2B9-based lateral flow device (LFD) to detect gluten from wheat, barley, and rye and deamidated gluten down to 2 ppm in food as well as its performance in food testing.

Abstract
The U.S. Food and Drug Administration Office of Women's Health (FDA OWH) has supported women's health research for ∼20 years, funding more than 300 studies on women's health issues, including research on diseases/conditions that disproportionately affect women in addition to the evaluation of sex differences in the performance of and response to medical products. These important women's health issues are studied from a regulatory perspective, with a focus on improving and optimizing medical product development and the evaluation of product safety and efficacy in women. These findings have influenced industry direction, labeling, product discontinuation, safety notices, and clinical practice. In addition, OWH-funded research has addressed gaps in the knowledge about diseases and medical conditions that impact women across the life span such as cardiovascular disease, pregnancy, menopause, osteoporosis, and the safe use of numerous medical products.

Abstract
Celiac disease (CD) is characterized by small intestinal damage, which is mediated by a gluten-driven inflammatory response. Establishing a robust diagnosis is critical for improved quality of life and prevention of co-morbidities, although treatment is associated with a substantial life-long burden of care for patients and families. Unfortunately, CD remains a challenging diagnosis. As awareness of the disease increases, more diagnoses of CD are being made by primary care physicians. In fact, many patients may not present to a gastroenterologist because their symptoms are not clearly linked to a gastrointestinal pathology. Also, many patients are starting a gluten-free diet without prior testing, a circumstance that leads to even more confusion. Lastly, the number of serologic and genetic tests, and the role of endoscopy, can be confusing. The purpose of this review is to examine diagnostic testing strategies, focusing on published guidelines, for the evaluation of patients with suspected CD.
