Prolamins in wheat, barley, and rye cause celiac disease (CD), non‐celiac gluten sensitivity (NCGS), and wheat allergies (WA). Although rice can be a suitable alternative, gluten‐free rice flour products are less technologically advanced. However, coconut flour and xanthan gum could enhance product quality, fiber content, and functional properties. This study employed a response surface D‐optimal mixture design to investigate the impact of substituting Sadri Hashemi rice flour (RF) (15.60%–31.19%) with low‐fat desiccated coconut flour (CF) (0%–15.59%) and xanthan gum (XG) (0%–0.31%) in 17 runs based on batter weight. Eleven responses were analyzed and exhibited significant and valid models (p < 0.0001), with satisfactory coefficient of determination (R2 > 0.85) values and non‐significant lack of fit (p > 0.1). Substitution at all levels significantly increased batter viscosity (R2 = 0.990) and specific weight (R2 = 0.995). Differences in cake crumb color (ΔE) decreased when RF was substituted with CF, while maximum ΔE elevation was observed with 0.31% XG due to synergistic effects with 5.09% CF (R2 = 0.974). Increasing the RF/XG ratio (0% CF) resulted in decreased water activity (aw), while increasing CF increased aw synergistically (R2 = 0.986). Moisture and texture hardness increased significantly with RF substitution up to 7.518% CF and 0.170% XG and 8.944% CF and 0.285% XG, respectively (R2 = 0.976 and 0.993). The volume index decreased with CF and XG (R2 = 0.989). Sensory acceptances were reduced by increasing XG while improved with optimal CF levels, predicted at 6.415% (R2 = 0.997), 6.784% (R2 = 0.999), 9.001% (R2 = 0.999), and 5.924% (R2 = 0.999) for color, taste, texture, and overall acceptance, respectively. Two‐sided prediction interval confirmation runs with 95% confidence (p ≤ 0.05) validated the models' accuracy and prediction of optimized combinations. The optimized gluten‐free cake formula (23.395% RF, 7.795% CF, 0% XG) achieved an 88.0% desirability score. Developing valid regression models facilitates a comprehensive investigation of cake quality and sensory properties, ensuring a viable gluten‐free product for individuals with gluten‐related disorders.

Purpose of Review: Celiac disease is a common chronic inflammatory condition of the small bowel triggered by gluten in wheat, rye and barley in the diet. Non-celiac gluten sensitivity presents with symptoms similar to celiac disease with the ingestion of gluten or other components of wheat. In this article, we review challenges presented by a gluten free diet for the treatment of both disorders. Recent Findings: Wheat is ubiquitous in the diet and medications/products. A registered dietitian is mandatory for patient education on the gluten free diet. Naturally gluten free foods provide a healthy diet for those with celiac disease. Whole grains labelled gluten free, including oats, are encouraged in the diet as refined grains may be deficient in fiber, protein, and micronutrients, particularly folate. Gluten contamination is the most common cause of persistent symptoms in celiac disease though shared equipment of food preparation may not be as large a problem as suspected. Most with celiac disease on a gluten free diet will fully recover and gain weight that poses a problem for those overweight to start. The gluten free diet may have a negative impact on quality of life for both celiac patients and their families. Those with hypervigilance of the gluten free diet and avoidance of dining out have the lowest quality of life. Summary: The gluten free diet is currently the only effective treatment for celiac disease. A registered dietitian is needed to educate patients on the complexity of the gluten free diet with a goal of healthy eating, maintaining a healthy weight, and avoiding disordered eating or diet hypervigilance; key to a good quality of life.

Gluten-induced celiac disease (CD) is a serious autoimmune disorder whose symptoms in most gluten-sensitive populations can only be relieved by strict lifelong adherence to a gluten-free diet (GFD). Sensors for immediate, on-site and quick detection of the gluten content in foods can effectively ensure the quality of life of gluten-sensitive people. In this article, gluten sensitivity and the pathogenesis of CD are introduced, and the recognition principle of gluten detection biosensors is elaborated. Finally, the application scenarios of biosensors with three different types of signal output: colorimetry, fluorescence and electrochemistry for the rapid detection of gluten in foods are summarized in order to provide a basis for research on sensors for the rapid detection of gluten in foods.

Background: Among human leukocyte antigen (HLA)-associated disorders, celiac disease has an immunopathogenesis that is particularly well understood. The condition is characterized by hypersensitivity to cereal gluten proteins, and the disease lesion is localized in the gut. Still, the diagnosis can be made by detecting highly disease-speciic autoantibodies to transglutaminase 2 in the blood. The aim: The study aimed to determine whether interleukin 10, Igg, IgA, progesterone, oestrogen, FSH and AMH st hormones afect celiac disease. Methods: This study was performed from 1 Jan 2023 to Sept 2023 and included 89 patients and 93 controls. On days 2-5 of the menstrual cycle, measurements of serum progesterone, FSH, AMH and oestrogen hormone were performed. Laboratory investigations included immunological factors which include the measurement of interleukin 10 levels by ELISA instrument, as well as measurement Igg, IgA, and chemical factors which include progesterone, FSH, AMH, and oestrogen hormones measured by cobas e 411 analyzer. Results: Evaluation celiac patients for T. IgG, G. IgG and G. IgA was made of (96.98, 13.82, 9.73%) respectively, compared with healthy control subjects was made (8.17, 8.31, 20.68) where (p = 0.001), while evaluation celiac patients for IL-10 was made of (375.8pg\ml), compared with healthy control subjects was made (7.45pg\ ml) where (p = 0.001), also evaluation celiac patients for AMH, oestrogen, FSH and progesterone was made (3.92ng/ml, 102.64 pg/ml, 5.15 mlU/ml and 11.20 ng/ml) respectively, compared with healthy control subjects was made (3.21ng/ml, 93.69 Kg, and 23.46 Kg\m²) respectively, 2 compared with healthy control subjects was made (160.39 cm, 61.93 Kg and 23.91 Kg\m²). Conclusions: Celiac disease may efect the T. IgG, G. IgG and G. IgA, also celiac disease afects the IL-10 but does not efect AMH, oestrogen, FSH and progesterone. Recommendation: Investigate the role of other cytokines, like IL-6 or TNF-α, in celiac disease. [ABSTRACT FROM AUTHOR]

Introduction: Gluten sensitivity (GS) is present in approximately 1% of the Malaysian population (Yap et al., PLoS One, 10, 2015, e0121908). GS is associated with several neurological conditions including epilepsy. Individuals with GS often exhibit a genetic predisposition associated with human leukocyte antigens (HLA) (Cecilio & Bonatto, Arq Bras Cir Dig, 28, 2015, 183). The purpose of this study was to investigate the prevalence of GS based on HLA genotyping in patients with epilepsy (PWE). Method: In total, 50 PWE and 50 controls were recruited. DNA was extracted from the venous blood samples and genotyped for HLA‐DQ2.2, DQ2.5, DQ7 and DQ 8. In this study, GS was diagnosed if any subject showed positive for one or more of the HLA‐DQ alleles. The type of epilepsy and number of antiseizure medication (ASM) used were recorded. Results: Only 2 alleles (HLA‐DQ 2.2 & HLA‐DQ8) were detected among 46 out of 100 subjects. 18 PWE and 19 controls were positive for HLA‐DQ8 (p = 0.836). 9 of the PWE, but no controls were positive for HLA‐DQ 2.2 (p = 0.003). 8 of these 9 PWE who were positive for HLA‐DQ 2.2 were also positive for HLA‐DQ8 (double positive), and these patients required multiple ASM for seizure control (p = 0.006). Conclusion: HLA‐DQ2.2 was seen highly prevalent in PWE. The double positives required more than one ASM for seizure control postulating malabsorption of ASM in these individuals. These findings suggest that HLA‐DQ genotyping may be a valuable additional test in PWE especially in those needing more than one ASM. Prescribing gluten‐free diet (GFD) to PWE with GS may potentially be an additional measure to achieve seizure control. [ABSTRACT FROM AUTHOR]

Background: A prior small-scale single center study suggested an association between celiac disease (CD)-type immunity and refractory temporal lobe epilepsy (TLE) with hippocampal sclerosis (HS). The present study addresses this putative association in a large, well-characterized group of drug-resistant epilepsy (DRE) patients. These patients were grouped based on the spectrum of CD and gluten sensitivity-associated antibodies. Methods: In this cross-sectional study, 253 consecutive adult epilepsy patients (135 females, 118 males; age 16–76 years) were categorized into three groups: (i) CD-positive group with either prior diagnosis of CD or CD-specific TG2/EmA antibodies, (ii) AGA-positive group with antigliadin antibodies (AGA) but without CD, and (iii) CD/AGA-negative group without any gluten sensitivity-associated antibodies or CD. Clinical and immunological findings were then compared among the groups. Results: TLE with HS was more common in the CD-positive group compared to CD/AGA-negative group (31.8% versus 11.9%, P = 0.019). Autoimmune disorders were more common in the AGA-positive group than in the CD/AGA-negative group (P = 0.025). Considering HS lateralization; left lateralization was more common in CD-positive group compared to CD/AGA-negative group (71.4% versus 25%, P = 0.030). TG6 seropositivity did not differ among the groups (P > 0.05). Conclusions: This study provides further evidence linking TLE with HS and CD-type autoimmunity suggesting that CD-type immune response to gluten can be one potential mechanism as a disease modifier leading to DRE and HS. Understanding these immunological factors is imperative for developing immunomodulatory or dietary treatments for DRE potentially preventing HS progression. [ABSTRACT FROM AUTHOR]

Neuralgic amyotrophy (NA) is a syndrome of abrupt onset severe pain in the shoulder usually on one side, followed by rapidly progressive weakness and wasting in the upper limb in asymmetric, patchy distribution due to multifocal neuropathy of brachial plexus. Atypical forms may present with involvement of other peripheral nerves including lumbosacral plexus, intercostal and phrenic nerves, and less frequently cranial nerves (CN) which can also be involved.[1] Here we presenting a case of atypical NA affecting bilateral upper limbs with CN involvement in a known patient of celiac disease.

We report on a group of patients with gluten sensitivity with and without coeliac disease presenting with unexplained sensory symptoms in the absence of structural pathology. Methods: The patients were selected from the gluten neurology clinic based at the Royal Hallamshire Hospital, Sheffield, UK, on the basis of sensory symptoms but normal neuroaxis imaging and peripheral nerve evaluation. Results: A total of 30 patients were identified with a mean age at presentation of 47 years. The prevalence of enteropathy was 78%. The sensory disturbance was characterised by tingling at 50%, numbness at 27%, pain at 20%, burning at 13% and "buzzing" feeling at 7%. The distribution of the sensory symptoms included hands and feet in 27% of the patients, torso in 27%, legs only in 23%, face in 17% and arms only in 10%. For five patients, the sensory disturbance was migratory and affected different parts of the body at any given time. After the introduction of a gluten-free diet, 77% of patients noted significant improvement in their sensory symptoms. In one-third of the patients, there was a complete resolution of the sensory symptoms. Conclusion: Unexplained sensory symptoms can be seen in patients with gluten sensitivity and respond to strict adherence to a gluten-free diet. [ABSTRACT FROM AUTHOR]

It is challenging to make diagnosis of non-celiac gluten sensitivity/non-celiac wheat sensitivity (NCGS/NCWS) in clinical practice, since there is no biomarker and diagnosis is based on response to gluten-free-diet (GFD). We used anti-gliadin antibody (AGA) for screening patients with IBS for gluten-sensitivity. 492 Adult-patients with IBS underwent screening for celiac disease and gluten-sensitivity using IgA anti-tissue transglutaminase antibody and IgA-AGA and IgG-AGA, respectively. Patients with positive AGA (IgA and/or IgG) were invited to follow GFD, those willing were put on GFD for 6-weeks. Responsive patients were given gluten re-challenge. Diagnosis of NCGS was confirmed if they had recurrence of symptoms. Of 492 patients with IBS, AGA was positive in 61(12.4 %), hence suspected to have gluten-sensitivity. Of 31 who agreed to participate and followed GFD for 6-weeks, 17 (54.8 %) had complete (>30 % improvement) and 10(32.2 %) had partial (>20 % improvement) response. All 17 complete-responders were given gluten re-challenge for 6-weeks, symptoms recurred in all and hence were confirmed to have NCGS/NCWS. Significant decrease in AGA levels occurred almost in all GFD-responders. 12.4 % IBS patients have biological evidence of gluten/wheat-sensitivity. Almost 87 % patients with IBS having AGA responded to GFD. The value of AGA may further be explored as a biomarker for screening for the presence of NCGS, before recommending this test for the clinical practice. [ABSTRACT FROM AUTHOR]

Individuals with childhood apraxia of speech (CAS) were reported to have genetic variations related to gluten sensitivity and some neuroanatomic changes, which could be associated with alterations in neurotransmitters levels such as glutamate and gamma-aminobutyric acid (GABA). The aim was to measure the levels of antigliadin immunoglobulin A (IgA) antibody, glutamate, and GABA in the plasma of children with CAS compared with children with delayed language development (DLD) and neurotypical (NT) children. The participants (N = 120) were in three groups: Group I for CAS (N = 30), Group II for DLD (N = 60), and Group III for NT (N = 30). The abilities of children in Groups I and II were evaluated. The plasma levels of antigliadin IgA, glutamate, and GABA were determined by enzyme-linked immunosorbent assay. The intelligence quotient and expressive language age in Group I were low compared with Group II (P = 0.001; 0.004). The levels of antigliadin IgA and glutamate in Group I were higher compared with the other two groups, whereas the level of GABA was lower (P < 0.0001). An imbalance between glutamate and GABA was found in Group I. In Group II, no measures differed from NTs except lower GABA levels (P = 0.0007). The elevated levels of antigliadin IgA antibody and glutamate demonstrated high sensitivity and specificity, differentiating children with CAS from children with DLD and NT children. The low levels of GABA contributed to the imbalance between the excitatory and inhibitory neurotransmitters' levels detected in children with CAS. [ABSTRACT FROM AUTHOR]

Background: Gluten sensitivity (GS) is one of the gluten-related disorders (GRDs). Patients with GS may have serum antibodies against tissue transglutaminase (tTG) (IgA and IgG) without any evidence of enteropathy. We aimed to evaluate both tTG-6 and tTG-2 antibodies to determine the prevalence of seropositive tTG-2 and tTG-6 antibodies in patients with multiple sclerosis (MS). Methods: In this cross-sectional study, we carried out serological tests (IgA & IgG anti-tTG-6 and tTG-2 antibodies) in patients with MS. Results: Seventy-two patients with MS were included in this study. Of them, seropositive patients for total (IgA + IgG) of tTG-6 and tTG-2 autoantibodies were 9.7% (95% CI, 4.2-18) and 5.6% (95% CI, 1.4-12.5), respectively. Conclusion: Anti-tTG-6 antibody testing may be necessary for early diagnosis of GS in patients with MS. More studies with larger sample sizes are warranted to confirm these data.

The popularity of "free-from" food products (FFFPs), which exclude several ingredients such as lactose, gluten, or sugar, is increasing globally. However, experts agree that avoiding these ingredients without medical reasons can lead to nutritional deficiencies. A representative consumer survey was conducted in Hungary (n = 1002); it focused on behaviors related to FFFPs, particularly lactose- and gluten-free products. This study revealed that consumers often consider "free-from" claims during shopping. Lactose- and gluten-free foods were popular, even among those without specific dietary needs. A distinct "free-from consumer group" (7.8% of the sample, predominantly women) was identified, who consume both lactose- and gluten-free foods frequently. However, only 15.4% of the group had medical reasons for their preference, such as lactose intolerance or gluten sensitivity. The majority (75.6%) chose these products without medical justification, relying on self-diagnosis, through the involvement of family members, or the belief that they were healthier. This consumer group accounts for nearly 6% of Hungary's adult population, exceeding 470,000 individuals. Extrapolating these figures to other European countries suggests that 25–30 million EU citizens might be in a similar situation, highlighting the need for improved health education and awareness-raising campaigns to prevent imbalanced nutrition and foster the recognition and treatment of real health problems.

Abstract Objective Health literacy levels among the general population predict better health outcomes and uptake of health services. Inequities in health literacy and uptake of health services are often observed in deprived neighborhoods. There is a paucity of data on literacy regarding celiac disease in Kuwait. Therefore, the present survey aims to address this paucity of data. Results We conducted a survey of 350 respondents in six governates of Kuwait. Although around 51% of respondents were aware of peanut allergy and gluten sensitivity, less than 15% were aware of celiac disease. More than 40% of respondents reported that a gluten-free diet should be promoted for everyone. Better awareness regarding CD was associated with Kuwaiti nationality, higher education levels and higher age. Among different governates, residents of Al-Asimah reported the highest awareness levels, while the rest of the governates did not differ significantly. While eating behavior did not significantly predict awareness regarding CD.

Introduction: Gluten is the combination of gliadin and glutenin within a fraction of wheat. Its fraction is used in food processing because of its unique structure-building attributes. The gluten in wheat flour forms a three-dimensional protein network when mixed and hydrated properly. Even those without a diagnosis of an illness linked to gluten are beginning to follow a GFD. Methodology: This study aimed to examine the knowledge and use of the gluten-free diet among the general population of Saudi Arabia. This cross-sectional study included participants 18 years and older. Frequencies and percentages were used for descriptive data. Results: A total of 793 were included in the study. More than half of the participants knew what gluten and gluten-free diet are. Females demonstrated a greater awareness of gluten-free diet and their use (%). Other questions on the prevalence of gluten-free diet use showed that 5% follow it rigorously, while 10.3% follow it with lapses. Conclusion: The majority of the respondents were aware of the gluten diet; mostly, the gluten-free diet was followed due to health-related lifestyles. Future research on a broader scale in SA is highly needed to better understand the Saudi population. [ABSTRACT FROM AUTHOR]

Coeliac disease (CD) and non-coeliac gluten sensitivity (NCGS) cause symptoms like those seen in patients with fibromyalgia (FM) and functional gastrointestinal disorders. There is no consistent data on frequency of these symptoms and no study performed duodenal biopsies to investigate CD/NCGS in Brazilian FM patients. Therefore, we sought to verify the prevalence of CD/NCGS in FM patients and the association between gastrointestinal manifestations and FM symptoms. Sixty-two individuals with FM (ACR2010) were recruited from FM outpatient clinics of a tertiary hospital. Clinical evaluation included the Widespread Pain Index (WPI), Severity Symptom Scale (SS), Polysymptomatic Distress Scale (PDS), and Fibromyalgia Impact Questionnaire (FIQ). Subjects were screened for the presence of coeliac antibodies and upper gastrointestinal endoscopy (duodenal biopsies) was performed for diagnosis of CD/NCGS. 46 (74.2%) women reported at least one digestive symptom: constipation, abdominal distension, loss of weight/inappetence, and nausea/vomiting. Fourteen (31.8%) presented macroscopic duodenitis and 2(4.5%) had duodenal lymphocytic infiltrates, but none met CD criteria. In 1(1.6%) patient NCGS was confirmed. There was association between presence of any digestive symptom and WPI and SS (fatigue, waking up tired, cognition), but no difference on FIQ between patients with and without gastrointestinal symptoms. Gastrointestinal complaints were frequent and associated with increased degree of polysymptomatic distress in FM patients, but presence of these symptoms was not related to overall impact of FM over different dimensions of the patient's life. Moreover, the prevalence of CD/NCGS was very low. This suggests that screening for CD in Brazilian FM patients might not be cost-effective, since the frequency of CD/NCGS was very low.

Celiac disease (CD) is a chronic, autoimmune disorder that affects the small intestine in response to ingesting gluten with long-term effects on multiple systems. Ways in which nurses can empower patients and families to manage CD within the scope of their practice are described. [ABSTRACT FROM AUTHOR]

In a previous study we used asymmetric-flow field-flow fractionation to determine the polymer mass (Mw), gyration radius (Rw) and the polydispersity index of glutenin polymers (GPs) in wheat (Triticum aestivum). Here, using the same multi-location trials (4 years, 11 locations, and 192 cultivars), we report the factors that are associated with the conformation (Conf) of the polymers, which is the slope of Log(Rw) versus a function of Log(Mw). We found that Conf varied between 0.285 and 0.740, it had low broad-sense heritability (H 2=16.8), and it was significantly influenced by the temperature occurring over the last month of grain filling. Higher temperatures were found to increase Rw and the compactness and sphericity of GPs. Alleles for both high- and low-molecular-weight glutenin subunits had a significant influence on the Conf value. Assuming a Gaussian distribution for Mw, the number of polymers present in wheat grains was computed for different kernel weights and protein concentrations, and it was found to exceed 1012 GPs per grain. Using atomic force microscopy and cryo-TEM, images of GPs were obtained for the first time. Under higher average temperature, GPs became larger and more spherical and consequently less prone to rapid hydrolysis. We propose some orientations that could be aimed at potentially reducing the impact of numerous GPs on people suffering from non-celiac gluten sensitivity. [ABSTRACT FROM AUTHOR]

Aims: Previous studies have reported conflicting results regarding prevalence of elevated LC (2–70%) in celiac disease (CD). This systematic review and meta-analysis assessed the prevalence of elevated LC at time of CD diagnosis and associated response to GFD. We also report the prevalence of CD in patients with unexplained elevation of LC. Methods: Studies assessing LC (aspartate aminotransferase [AST] and alanine aminotransferase [ALT]) in CD patients were eligible. Studies with < 50 cases or in pediatric populations were excluded. Results: In total, 20 studies assessing prevalence of elevated LC in 4,265 participants with newly diagnosed CD (mean age = 35.6 ± 6.5 years, 69.8% female) were included. Pooled prevalence of elevated LC was 18.7% (95% CI 13.8–24.8; I2 = 95%). Normalization of elevated LC was seen in 83.1% (95% CI 73.4–89.7; I2 = 79%, 11 studies) of patients after GFD. On meta-regression, age at CD diagnosis, gender, and Marsh grading were not associated with elevated LC. Among 979 participants (7 studies) with unexplained elevation of LC, pooled seroprevalence and biopsy-proven CD was 6.4% (95% CI 2.9–10.3, I2 = 71%) and 4.5% (95% CI 2.6–7.7, I2 = 67%), respectively. Conclusion: Elevated LC are seen in approximately one-fifth of patients at CD diagnosis with majority normalizing after GFD. Age, gender, and degree of intestinal damage are not predictive of elevated LC. In the appropriate clinical scenario, liver tests should be serially monitored in CD reserving workup for additional causes after a trial of GFD. Patients with unexplained elevation of liver tests should be screened for celiac disease. [ABSTRACT FROM AUTHOR]

Whatever the type of food intolerance and allergy, with the correct adherence to a moderate diet, there are additional costs. It’s no secret, because with daily shopping, anyone can find that the price of gluten-free products is higher than that of non-gluten-free foods. For a conscious shopper, this can be 20%, but for a family it can be as much as 30 or 50% if the whole family wants to eat gluten-free. However, it is also worth examining what is the reason for the larger-than-usual price difference, in which case people need to understand the production process and sourcing to get an answer. It is usually made from less commonly grown raw materials, which are more difficult to obtain and more expensive. These plants often require more manual labour, which can result in higher prices. Care must be taken to avoid cross-contamination at the processing plant as well as during transport - this can also lead to additional costs. Not to mention that it should also be prepared separately in restaurants to rule out the possibility of cross-contamination.

Celiac disease is an immune-mediated illness to gluten exposure in genetically susceptible patients. It is characterized by chronic lymphocytic inflammation of the small bowel leading to villous atrophy and its associated complications. The global prevalence of celiac disease is increasing, due in part to improved screening tests and simplified diagnostic criteria. Novel therapies are being developed and include proteolytic enzymes, sequestering agents, and immunotherapies. A strict gluten-free diet, however, remains the mainstay of treatment. In this comprehensive review, we discuss the epidemiology, definitions, diagnosis, and treatment of celiac disease.

BackgroundParoxysmal gluten-sensitive dyskinesia is a subtype of movement disorder classified as canine paroxysmal dyskinesia (cPD), which until now has only been described in Border Terriers (BT).ObjectivesOur aim was to report cPD with positive gluten serology in dog breeds other than BT.AnimalsThirty-one client-owned dogs with suspected cPD were examined in this study.MethodsThe hospital records of the dogs where the serum was tested for modified gliadin peptide immunoglobulin G (gliadin IgG) and tissue transglutaminase-2 immunoglobulin A (transglutaminase-2 IgA) were studied. A total of 31 dogs were presented to the clinic with cPD. A work-up consistent with Tier 1 or Tier 2 confidence levels for canine epilepsy was undertaken in all dogs. The dogs' diets and episode descriptions or videos in 16/31 cases were additionally studied. A follow-up was held to inquire about the dogs' wellbeing and response to the diet changes.ResultsFourteen of the 31 dogs tested positive for gluten sensitivity with either gliadin IgG or transglutaminase-2 IgA or both ratios elevated. In seven dogs, serology was classified as questionable with gliadin IgG or transglutaminase ratios mildly elevated. Ten dogs tested negative. According to the owners' reports, five of the dogs that tested positive had no more episodes after changing to a strictly gluten-free diet, with one of the dogs relapsing twice after being fed treats containing gluten. Three dogs had a reduction in episode frequency of >50%, and two dogs had shorter and less intense episodes.ConclusionA considerable subset of dog breeds presented for presumed cPD showed laboratory signs of gluten sensitivity and responded to a gluten-free diet.

Gluten is a structural protein for bakery products and its lack causes undesirable changes in the texture, color, and porosity of these products. Therefore, the use of gluten alternatives such as hydrocolloids, enzymes, and proteins, are essential in providing these products. The aim of this research was to evaluate the properties of gluten-free bread (physicochemical properties such as specific volume and porosity, stiffness, extensibility, and color parameter, as well as sensory properties) in the presence of 0, 0.5, 1, and 1.5% concentrations of gums including Cress seed gum (C) and Basil gum (B) compared to Hydroxypropyl Methylcellulose (HPMC) (H). The results indicated that adding gums to bread decreased stiffness and color parameters and increased specific volume, extensibility, and sensory properties. Based on the comparison between C, B and HPMC, basil gum could improve volume, porosity, and sensory score more than C and H. Also, the HPMC was more effective on the color parameter of gluten-free bread. Based on the results, addition of basil gum to the gluten-free bread recipe could improve the crumb texture, specific volume, sensory properties, as well as overall quality of the product. Basil gum as a novel gum increased water absorption, texture, and the best results were obtained in 1% basil gum. The results of bread quality parameters indicated C0B1H0 had high specific volume and porosity. Therefore, basil seed gum can be a novel and useful gluten substitute for gluten-free bread baking purposes. [ABSTRACT FROM AUTHOR]

Several studies have reported improved disease symptomatology in ulcerative colitis (UC) patients consuming a gluten free diet. This observation coupled with diversity depletion in the gut microbiota of UC patients led us to hypothesize that UC-associated enteric microbes differentially metabolize dietary gluten to produce immunogenic products that promote inflammation. Gluten concentration in stool was determined using gluten-specific ELISA, and gluten intake was assessed by food frequency questionnaire (FFQ) in UC (n = 12) and healthy controls (HC; n = 13). Gluten-metabolizing bacteria were isolated on minimal media supplemented with 1% gluten from UC and HC and identified by 16S rRNA profiling. Cell-free culture media from gluten metabolizing gut bacterial isolates was assessed for immunogenicity in vitro using HT29 colonocytes. Compared to HC, UC patients did not consume gluten differently (Mann–Whitney; p > 0.10) and exhibited equivalent levels of gluten in their feces (Mann–Whitney; p = 0.163). The profile of gluten-degrading bacteria isolated from UC stool was distinct (Chi-square; p ≤ 0.0001). Compared with Enterococcus isolates, products of gluten degradation by Bacillus strains induced higher IL8 and lower occludin (Mann–Whitney; p = 0.002 and p = 0.059, respectively) gene expression in colonocytes irrespective of whether they originated from UC or healthy gut. Members of HC and UC microbiota exhibit gluten-degrading ability, metabolites of which influence genes involved in inflammation and barrier function in enteric colonocyte cultures. Preliminary findings of this study warrant further investigations into the mechanisms by which gut microbiota contribute to UC pathogenesis through gluten degradation. [ABSTRACT FROM AUTHOR]

Gluten-related disorders in humans comprise different entities, including coeliac disease. Patients typically have measurable titers of anti-gliadin IgG or IgA (AGAs) and anti-transglutaminase-2 IgA (TG2). In addition to intestinal symptoms, human patients often show various neurological complications. In dogs, the neurological manifestation is rarely reported. Here we describe the muscle and nerve biopsies of an 11-year-old, male Border Terrier presenting with lower motor neuron signs submitted for histological examination. Examination of the biopsies showed an oligofocal lymphohistiocytic and plasmocytic myositis and a diffuse neuropathy of mixed nodo-paranodal and demyelinating type. Suspecting a neuromuscular form of breed-related gluten hypersensitivity, measurements of AGAs and TG2 antibodies were performed. Both titers ranged above control values. Hence, a gluten-related neuromyopathy was diagnosed. A gluten-free diet was prescribed and a complete disappearance of clinical signs was observed. Gluten-related disorders should be considered as a differential diagnosis in dogs with intestinal and neuromuscular signs. [ABSTRACT FROM AUTHOR]

Cerebellar manifestations have been described in patients with gluten sensitivity (GS)-related disorders. A better understanding of the neurological manifestations of GS requires the use of neuroimaging techniques. We performed a systematic review on neuroimaging findings in GS patients with cerebellar symptoms. We also included a specific search on neuroimaging findings in GS patients with cerebellar manifestations on a gluten-free diet (GFD). PubMed, Embase, and Bireme were systematically searched to identify studies assessing neuroimaging features of adults with cerebellar manifestations and GS with or without enteropathy on a GFD. Ten studies with a total of 222 adult-GS patients were included. Magnetic resonance imaging was used in 100% of the studies. Cerebellar atrophy was evaluated in 7 studies and observed in 63% of the patients. White matter abnormalities were described in 2 studies. Single-photon emission computed tomography was used in 2 studies, and decreased cerebellar perfusion was detected in 92% of the included patients. No study employed nuclear medicine after the start of GFD. Magnetic resonance spectroscopy (MRS) was performed in 2 studies before and after GFD. An increase in the Naa/Cr ratio in cerebellar vermis was seen in 98% of the cases on a strict GFD. Cerebellar atrophy was found to be a prevalent condition in GS patients. MRS demonstrated to be useful in the follow-up of GS patients with cerebellar manifestations on a GFD. Prospective studies using nuclear medicine imaging are needed to study brain changes in GS patients on a GFD. [ABSTRACT FROM AUTHOR]

The popularity of “free-from” food products (FFFPs), which exclude several ingredients such as lactose, gluten, or sugar, is increasing globally. However, experts agree that avoiding these ingredients without medical reasons can lead to nutritional deficiencies. A representative consumer survey was conducted in Hungary (n = 1002); it focused on behaviors related to FFFPs, particularly lactose- and gluten-free products. This study revealed that consumers often consider “free-from” claims during shopping. Lactose- and gluten-free foods were popular, even among those without specific dietary needs. A distinct “free-from consumer group” (7.8% of the sample, predominantly women) was identified, who consume both lactose- and gluten-free foods frequently. However, only 15.4% of the group had medical reasons for their preference, such as lactose intolerance or gluten sensitivity. The majority (75.6%) chose these products without medical justification, relying on self-diagnosis, through the involvement of family members, or the belief that they were healthier. This consumer group accounts for nearly 6% of Hungary’s adult population, exceeding 470,000 individuals. Extrapolating these figures to other European countries suggests that 25–30 million EU citizens might be in a similar situation, highlighting the need for improved health education and awareness-raising campaigns to prevent imbalanced nutrition and foster the recognition and treatment of real health problems.

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

Celiac disease (CD) is an immune condition that patients have to deal for lifelong. It affects almost 1% of the general population and determines lifestyle and social changes due to diet control and restrictions. Gluten ingestion in patients with CD determines bloating, abdominal pain, constipation, nausea and vomiting conducting to anaemia, osteoporosis, neurological problems, herpetiform dermatitis can occur later in life. The incidence of CD increased especially for women (17.4 cases of 100,000 for one year); for men, the incidence is 7.8 per 100,000 people in one year. More and more children are also diagnosed with celiac disease, 21.3 per 100,000 person-years compared to 12.9 per 100,000 in adults. Wheat allergy, gluten sensitivity and celiac disease represent medical conditions that are correlated with cereal consumption and become of increased interest for consumers in order to have an appropriate diet or a preventive one. Gluten free diet (GFD) become more popular among consumers and its popularity is increasing, health practitioners started to question if there is a real health benefit for everyone or just a medical nutrition therapy for those in need.

Popular media messaging has led to increased public perception that gluten‐containing foods are bad for health. In parallel, 'ancient grains' have been promoted with claims that they contain less gluten. There appears to be no clear definition of 'ancient grains' but the term usually includes einkorn, emmer, spelt and Khorasan wheat. Gluten is present in all wheat grains and all can induce coeliac disease (CD) in genetically susceptible individuals. Analyses of 'ancient' and 'modern' wheats show that the protein content of modern bread wheat (Triticum aestivum) has decreased over time while the starch content increased. In addition, it was shown that, compared to bread wheat, ancient wheats contain more protein and gluten and greater contents of many CD‐active epitopes. Consequently, no single wheat type can be recommended as better for reducing the risks of or mitigating the severity of CD. An estimated 10% of the population of Western countries suffers from gastrointestinal symptoms that lack a clear organic cause and is often referred to as irritable bowel syndrome (IBS). Many of these patients consider themselves gluten sensitive, but in most cases this is not confirmed when tested in a medical setting. Instead, it may be caused by gas formation due to fermentation of fructans present in wheat or, in some patients, effects of non‐gluten proteins. A significant overlap of symptoms with those of CD, IBS and inflammatory bowel disease makes a medical diagnosis a priority. This critical narrative review examines the suggestion that 'ancient' wheat types are preferred for health and better tolerance. [ABSTRACT FROM AUTHOR]

Objective: Celiac disease (CD) is an autoimmune-mediated disease characterized by small intestinal mucosal damage after gluten exposure in genetically predisposed individuals. Although it is known that the prevalence of CD in siblings of celiac patients is more common than the normal population, there are limited studies on the frequency of non-celiac gluten sensitivity (NCGS) and wheat allergy (WA). In this study, we aimed to investigate the prevalence of CD, NCGS and WA in siblings of children with CD. Material and Methods: Siblings of patients diagnosed with CD in our pediatric gastroenterology clinic were examined for CD, NCGS and WA. CD diagnosed according to The European Society for Paediatric Gastroenterology Hepatology and Nutrition guideline. NCGS was diagnosed with the disappearance of symptoms related to gluten intake with gluten elimination, while WA was diagnosed with the absence of wheat-related symptoms after wheat removal from the diet and wheat-specific immunoglobulin E assays. Demographic and clinical features and laboratory parameters of the cases were recorded. Results: 50 siblings of 59 celiac patients eligible for the study [25 males (50%), mean age±standard deviation; 11.5±3.66 years (4-17 years)] were included. Three of the siblings [6%, 95% confidence interval (CI): 1.56-17.54) were diagnosed with CD, and 7 (14%, 95% CI: 6.28-27.36) were diagnosed with NCGS. There was no sibling with a diagnosis of WA. Conclusion: In our study, both CD and NCGS were found to have a higher prevalence in siblings of CD patients. When screening siblings of patients with CD, cases with symptoms and normal serology and endoscopy findings should be evaluated for NCGS. [ABSTRACT FROM AUTHOR]

Whatever the type of food intolerance and allergy, with the correct adherence to a moderate diet, there are additional costs. It's no secret, because with daily shopping, anyone can find that the price of gluten-free products is higher than that of non-gluten-free foods. For a conscious shopper, this can be 20%, but for a family it can be as much as 30 or 50% if the whole family wants to eat gluten-free. However, it is also worth examining what is the reason for the larger-than-usual price difference, in which case people need to understand the production process and sourcing to get an answer. It is usually made from less commonly grown raw materials, which are more difficult to obtain and more expensive. These plants often require more manual labour, which can result in higher prices. Care must be taken to avoid cross-contamination at the processing plant as well as during transport - this can also lead to additional costs. Not to mention that it should also be prepared separately in restaurants to rule out the possibility of cross-contamination. [ABSTRACT FROM AUTHOR]

&lt;b&gt;Background and Objective:&lt;/b&gt; Autism Spectrum Disorder (ASD) is a range of neurodevelopmental disabilities that lack a clear etiology. To date, studies investigating the role of immune reactivity to gluten in ASD have been inconsistent. This study aimed to compare levels of gluten reactivity markers in 319 ASD patients to 172 of their unaffected siblings and 322 of unrelated healthy controls (UHC). &lt;b&gt;Materials and Methods:&lt;/b&gt; Patients younger than 12 years old diagnosed with ASD via experienced child psychiatrists and neuro-pediatricians were recruited and gluten reactivity markers and gastrointestinal (GI) complaints commonly found in children with ASD were also investigated. Serum levels of anti-gluten and anti-tissue transglutaminase IgA (anti-TTG IgA) were measured via ELISA. &lt;b&gt;Results:&lt;/b&gt; No significant differences were detected in IgA levels and IgG levels for anti-TTG among all groups (p<0.05). The anti-gliadin IgG levels were significantly higher in ASD patients and their siblings compared to the UHC group (p<0.05). Also, those IgG levels were not associated with any GI complaints or Electroencephalogram (EEG) abnormalities (p>0.05). &lt;b&gt;Conclusion:&lt;/b&gt; The data suggested gluten sensitivity has no role in ASD pathophysiology or its comorbid symptoms.

Several studies have reported improved disease symptomatology in ulcerative colitis (UC) patients consuming a gluten free diet. This observation coupled with diversity depletion in the gut microbiota of UC patients led us to hypothesize that UC-associated enteric microbes differentially metabolize dietary gluten to produce immunogenic products that promote inflammation. Gluten concentration in stool was determined using gluten-specific ELISA, and gluten intake was assessed by food frequency questionnaire (FFQ) in UC (n = 12) and healthy controls (HC; n = 13). Gluten-metabolizing bacteria were isolated on minimal media supplemented with 1% gluten from UC and HC and identified by 16S rRNA profiling. Cell-free culture media from gluten metabolizing gut bacterial isolates was assessed for immunogenicity in vitro using HT29 colonocytes. Compared to HC, UC patients did not consume gluten differently (Mann–Whitney; p > 0.10) and exhibited equivalent levels of gluten in their feces (Mann–Whitney; p = 0.163). The profile of gluten-degrading bacteria isolated from UC stool was distinct (Chi-square; p ≤ 0.0001). Compared with Enterococcus isolates, products of gluten degradation by Bacillus strains induced higher IL8 and lower occludin (Mann–Whitney; p = 0.002 and p = 0.059, respectively) gene expression in colonocytes irrespective of whether they originated from UC or healthy gut. Members of HC and UC microbiota exhibit gluten-degrading ability, metabolites of which influence genes involved in inflammation and barrier function in enteric colonocyte cultures. Preliminary findings of this study warrant further investigations into the mechanisms by which gut microbiota contribute to UC pathogenesis through gluten degradation.

Background/Aims Most patients with irritable bowel syndrome (IBS) report food-related aggravation of symptoms. Wheat/gluten is one of the most commonly incriminated. We studied the prevalence of self-reported wheat sensitivity in patients with IBS and in a healthy population from a region in India consuming mixed-cereal diets, correlated it with serological and human leukocyte antigen (HLA) markers of celiac disease, and evaluated the response to a wheat-free diet. Methods We surveyed 204 patients with IBS and 400 healthy persons for self-reported wheat sensitivity. Testing for IgA anti-tissue transglutaminase and HLA DQ2 or DQ8 was done in individuals who reported wheat sensitivity. Consenting persons with wheat sensitivity were put on wheat-free diet and monitored for symptom change. Results Twenty-three of 204 patients with IBS (11.3%) and none of the healthy subjects self-reported wheat sensitivity. Of 23 patients, 14 (60.9%) were positive for HLA DQ2 or DQ8 and none for anti-tissue transglutaminase antibody. After 6 weeks on wheat-free diet, all 19 participating patients reported clinical improvement; fewer patients had bloating, diarrhea, constipation, and easy fatigue. Conclusions Eleven percent of patients with IBS self-reported wheat sensitivity. None of them had positive celiac serology; 60.9% were positive for HLA DQ2 and DQ8, suggesting a possible genetic basis. All of them improved symptomatically on a wheat-free diet.

Objective: To determine the frequency and pattern of neurological features in patients diagnosed with gluten related disorder (GRD). Study Design: Cross sectional analytical study. Place and Duration of Study: Pak Emirates Military Hospital Rawalpindi, from Jan 2016 to Jun 2018. Patients and Methods: This study included cases who presented initially with neurological manifestations and later diagnosed having GRD, including coeliac disease (CD) or non-coeliac gluten sensitivity (NCGS). Cases fulfilling inclusion and exclusion criteria were selected. Record of patients was obtained from the hospital stats office. Cases were analyzed for clinical symptomatology, laboratory and neuro-radiological findings. Data was collected using performa and analysis was done using SPSS version 20. Results: Out of 31 patients, 18 (58.1%) were male and 13 (49.9%) were females. Mean age was 28.8 ± 10.4 years. Nineteen (61.3%) were diagnosed with CD while 12 (38.7%) had NCGS. Anti-TTG antibodies were detected in 17 out of 19 patients with CD, while anti Gliadin antibodies were positive in 11 out of 12 patients with NCGS. These results were statistically significant with p-value

Coeliac disease, an autoimmune disease, is caused by ingestion of gluten in genetically susceptible individuals. The currently used modified-Marsh grading, used to assess mucosal injury, is fraught with interobserver and intraobserver variability. The aim is to reduce this variability by villous length morphometry. Our prospective study was conducted on newly diagnosed cases of coeliac disease that were assessed by serohaematological profile, and duodenal biopsies were evaluated by modified Marsh grading. Villous length was measured in Grades 2, 3a and 3b using an eyepiece graticule lens calibrated with a stage micrometer. Severity of mucosal injury in different Marsh grades was significantly correlated to mean villous length, elevation of mean IgA tTG and drop in haemoglobin. [ABSTRACT FROM AUTHOR]

Gluten related disorders (GRD), which include celiac disease, non-celiac wheat sensitivity and wheat allergy are heterogeneous conditions triggered by ingestion of gluten-containing grains. Together, their prevalence is estimated to be ~5% in the general population, however, in the last years the number of diagnoses has been rapidly increasing. To this day, the gold standard treatment for these disorders is the complete removal of gluten-containing grains from the diet. Although this therapy results effective in the majority of patients, up to 30% of individuals affected by GRD continue to present persistent symptoms. In addition, gluten-free diet has been shown to have poor nutritional quality and to cause a socio-economic burden in patients' quality of life. In order to respond to these issues, the scientific community has been focusing on finding additional and adjuvant non-dietary therapies. In this review, we focus on two main gluten related disorders, celiac disease and non-celiac wheat sensitivity. We delineate the actual knowledge about potential treatments and their relative efficacy in pre-clinical and clinical trials.

Objective: Gluten neuropathy (GN) is the term used to describe peripheral neuropathy that occurs in patients with gluten sensitivity (GS) or coeliac disease (CD) in the absence of other risk factors. We aimed to describe the neurophysiological progression rate of GN across time and look into the potential role of genetic susceptibility in its development. Methods: This is a cohort study of 45 patients with GN with a mean follow-up period of 8 ± 5 years. The assessments included clinical and neurophysiological data and HLA-DQ genotyping. Results: The mean age at diagnosis was 60 ± 12 years. The majority of patients had a length-dependent neuropathy (75.6%), whereas the rest were diagnosed with sensory ganglionopathy (SG). DQA1*02-positive patients were more likely to suffer with SG compared to the DQA1*02 negative patients (60% versus 13.8%, p = 0.009). There was also a trend for statistical significance regarding the DQB1*06 allele and the DQA1*01/DQB1*06 haplotype were found more frequently in patients with GN than in healthy controls (p = 0.026 and p = 0.047, respectively). A linear effect of time on the neurophysiological findings was found in radial sensory nerve action potential (1.9% mean annual decrement, p = 0.036), sural sensory nerve action potential (3.3% mean annual decrement, p = 0.013) and tibial nerve motor compound action potential (6.5% mean annual decrement, p < 0.001) amplitudes, independently from age or gender. Conclusions: GN is a late manifestation of GS and CD. The majority of patients have the length-dependent neuropathy with a linear deterioration over time. HLA genotyping of GS and CD patients who suffer from neuropathic symptoms is recommended as it can help identifying patients at risk for developing SG. [ABSTRACT FROM AUTHOR]

Migraine is common in celiac disease (CD) and usually improves on a gluten‐free diet (GFD). The benefit for people impacted by migraine without CD is poorly evidenced. A GFD may have adverse health consequences and is expensive. [ABSTRACT FROM AUTHOR]
