After consumer acceptance against various attributes of aglutenic cupcake, the product will be provided in polyethylene bags containing 28 cupcakes (35gm by weight/cupcake, 2 cupcakes for each day) providing approximately 20% daily value (DV) of energy. Cupcakes of equal weight and size made with rice flour (mostly used recipe) will be provided to the control group. Further product will be provided on follow-up visits. The compliance to a gluten free diet GFD and supplemented product will be confirmed by a Food Frequency Questionnaire (FFQ).
The goal of this clinical trial was to investigate if intestinal deamidation of gliadin from wheat bread could be hindered by adding a E304i/zinc additive. The study was a randomized double-blind 4-week crossover intervention in 20 healthy volunteers in which the participants ingested 2 bread rolls a day during the intervention weeks. The question it aimed to answer was if there was a difference in blood levels of deamidated gliadin peptides after ingestion of the reference wheat bread compared with the wheat bread containing the food additive.
Celiac disease (CD) was diagnosed for years almost exclusively in children. This is due to the fact that in adulthood it manifests in a much more attenuated form, while the classic form with severe diarrhea, malnutrition and dehydration is observed almost exclusively in children. Classic studies, carried out prior to the widespread use of serology as a CD diagnostic tool, already showed that there is variability in gluten sensitivity and that in a non-negligible proportion of cases (10%) gluten sensitivity appears to be transient. Subsequent studies, including patients diagnosed by serology or population screening studies, suggest that progression to gluten latency or tolerance may occur in a higher proportion of patients, ranging from 20 to 50% depending on the geographical region. In the first decade of the 2000s, the researchers group performed a prevalence observational cross-sectional study survey in Catalonia (autonomous region in the northeast of Spain) that accurately reflected the distribution of the reference Catalan population in terms of sex and age. The results showed a drastic and significant drop in the prevalence of CD disease in relation to age, with the prevalence of CD in children being 5 times higher than adults (1:71 vs. 1:357). Strikingly, the reduction in prevalence was especially notable in the first 4 years of life. Two possibilities were proposed to explain this unexpected finding in a disease that is lifelong: 1) The existence of an environmental effect (cohort effect) acting as a disease trigger in early childhood during the study period (e.g., bacterial or viral infections, vaccines, food policies related to gluten introduction, use of antibiotics, etc.). 2) The appearance of age-related tolerance to gluten in a proportion of cases. Interestingly, it has been suggested that immunological tolerance might be more frequent in children diagnosed with CD before the age of two. The aims of the present epidemiological study are: 1) to determine the prevalence of CD in Catalonia in children under 5 years of age and compare it with the results obtained in the previous 2004-2007 study; 2) to investigate the potential effect of environmental factors on disease prevalence; and 3) to evaluate longitudinally the appearance of tolerance to gluten in the CD cases detected. Therefore, this study has been designed using exactly the same CD screening methodology and reproducing the reference population in the same geographical area as the previous 2004-2007 study.
Celiac disease (CD) is an autoimmune disease that occurs in people who are genetically predisposed to gluten consumption (1). The prevalence of the disease is about 1-2% and it is more common in women than in men, and in children than in adults (2). The only current treatment for celiac disease is a strict, lifelong gluten-free diet. This involves the complete elimination of gluten from the diet. Gluten is not only present in some cereals such as wheat, rye, barley and oats, but is also found in many foods that have been processed. In addition to being safe, the gluten-free diet must also be balanced. Following a gluten-free diet creates psychological and social problems for the people who have to follow it (3). It has been seen in several studies that people with celiac condition can feel different and excluded, as it is difficult to eat out, to make sure that the food is gluten-free and to avoid cross-contact (4-8). Due to the complicate situation of people with celiac disease, they do not hesitate to seek information about the management of their diseas. That is why people with celiac disease turn to social networks, as a rapid, visual and accessible way to share information (9-11). In line with the objectives of the University to which the Gluten3S research group belongs to (University of the Basque Country, UPV/EHU), the group has been aware for some time of the importance of disseminating science on social networks in order to make the results of the research reach the general public. It is considered that creating a nutritional education programme about CD and Gluten-Free Diet (GFD), delivered by experts in the field, could be useful in improving knowledge and attitudes about this matter. This will empower people with CD to improve their self-care and take control of their situation. Furthermore, it is also interesting to design the programme in such a way that the impact of the intervention can be measured, always with the intention of continuous improvement and reaching people with celiac disease and their environment in an effective way. The educational intervention will be carried out for one month and is aimed at adults with coeliac disease or adults with coeliac relatives who are involved in their care. Each day a post will be uploaded to Instagram with specific, accurate and current information. The content of the intervention has been divided into 5 main blocks: 1) general concepts about CD, 2) balanced GFD, 3) food labelling, 4) cross-contact/cross-contamination, 5) new research on CD and useful resources for disease management. The evaluation of the intervention will be carried out through pre- and post-intervention questionnaires.
Celiac disease (CD) is a systemic autoimmune gluten-dependent enteropathy in subjects with HLA DQ2/8. CD prevalence is more than 1% with a progression to 2% in adulthood. Among the group at risk such as first-degree relatives, subjects with autoimmune diseases (eg type 1 diabetes) or with syndromes (Down's disease, Turner) the prevalence reaches 5-8%. Recently, in pediatrics CD diagnostic criteria have been modified and the intestinal biopsy can be omitted in presence of a specific clinical and laboratory picture. In the remaining pediatric cases and in all adult patients, the biopsy is fundamental for the diagnosis. The clinical manifestation of CD not always depends on the enteropathy and on the related symptoms, but it can be characterized by extra-intestinal symptoms (eg chronic fatigue, anemia, arthralgia, cerebellar ataxia, alterations of dental enamel) that often hamper a rapid CD recognition delaying the diagnosis especially in adults. Symptoms are not always related to intestinal injury and may be present even when intestinal mucosa is normal. This condition is known as potential CD in which serum IgA anti-transglutaminase antibodies (anti-ttg) are generally positive at low concentrations (eg higher 2-3 times than the cut-off) or positive occasionally. In this clinical context, the gluten-free diet is an effective therapy able to improve the clinical picture and to stop the anti-ttg production. Recent observations, especially in pediatric field, have shown that in potential CD the immunological analysis of intestinal biopsies is characterized by the presence of anti-ttg deposits in the intestinal mucosa which predict the development of intestinal atrophy in a time span of 3- 5 years. Furthermore, these deposits disappear with the diet-therapy. In pediatric field, the diagnostic specificity of mucosal anti-ttg (anti-ttg-m) is between 95-98%, while the sensitivity is 100%. In adults, anti-ttg-m show 100% sensitivity in typical celiac disease (characterized by high serum anti-ttg concentrations and intestinal mucosa atrophy), while no results are available about potential celiac disease. Moreover, in adults data about the specificity of anti-ttg-m in infectious, oncological and inflammatory diseases of the gastro-intestinal tract are not available. The main study objectives are to evaluate anti-ttg-m sensitivity in patients with typical celiac disease and anti-ttg-m specificity in patients with oncological and inflammatory bowel diseases.
Coeliac disease (CD) is a systemic process of autoimmune nature related to the existence of a permanent intolerance to gluten and manifests itself in genetically susceptible individuals. It has a global prevalence of 0.5-1.5%. The diagnosis of CD should be made in patients following a normal gluten-containing diet and is based on coeliac serology and histopathological changes of the small intestinal mucosa. However, nowadays many patients come to their doctor to rule out CD after having started a gluten-free diet (GFD) with improvement of symptoms. In this scenario, making the diagnosis of CD remains a challenge, as it must be considered that most CD-associated changes revert after gluten withdrawal. An essential finding of CD is the increased number in total intraepithelial lymphocytes (IEL) in the duodenal mucosa, later characterized by an expansion of γδ+ and CD8+ IEL coupled to a decrease in CD3- IEL. An accurate quantification of the γδ+ subset became possible with the introduction of flow cytometry. In 2002, Spanish investigators proposed a diagnostic algorithm for paediatric CD that included the combined use of a high percentage of γδ+ and a low percentage of CD3- IEL, which was termed the coeliac lymphogram, which has been shown to be very accurate for the diagnosis of CD. Thus, the use of flow cytometric phenotyping of IEL may strengthen the diagnosis of CD when it is not straightforward. This study will provide information about the potential usefulness of T-cell flow cytometric coeliac patterns as CD biomarkers to confirm the diagnosis of CD in patients who have already started a GFD. These results may help to make decisions in specific situations of routine clinical practice, avoiding bothersome gluten reintroduction and delays in diagnosis.
This is a decentralized study to primarily explore a novel objective digital biomarker (i.e., Gluten Dependency Index) for celiac disease-related responses triggered by gluten exposure using a wearable biosensor. This study also explores a novel objective blood biomarker specific to celiac disease activity and evaluates participant symptoms, lifestyle and an objective comprehensive measurement (e.g., activity, stress and sleep) in celiac disease participants. Approximately 170 well-controlled celiac disease participants (Cohort A) and 40 celiac disease participants with persistent symptoms (Cohort B) will be monitored for 13 and 8 weeks in the observation period, respectively, in a home-based setting using the wearable biosensor along with a mobile platform including some electronic questionnaires. The wearable biosensor continuously records biosensor data. These data will be used to develop a new algorithm for Gluten Dependency Index and calculate the Gluten Dependency Index, Activity Value, Stress Value, or Sleep Time. Participants will report celiac disease-related symptoms, diet (including any accidental gluten exposures), exercise, menstruation questionnaires in CDSD and mobile platform questionnaire (MPFQ), which is originally designed by the Sponsor. All participants both in Cohort A and B are required to maintain gluten-free diet throughout the study. Only participant who are enrolled in Cohort A will be required gluten challenge.
The investigators conducted a retrospective, observational cohort study which enrolled CD subjects aged 2-18y, diagnosed between Jan 2016 and Dec 2020. Demographic and laboratory data were collected at diagnosis and 1y after adherence to GFD. ID was determined according to hemoglobin and ferritin levels. The investigators compared CD subjects with and without ID at CD diagnosis in relation to TTG normalization at 1y.
Celiac is a chronic autoimmune disease that is treated with a gluten-free diet. Adolescents with celiac disease were affected differently by the restrictions during the COVID-19 pandemic. The aim of this study was to determine the compliance with a gluten-free diet during in adolescents with celiac disease during the Covid-19 pandemic and identify the associated factors. The sample of this study consisted of 85 adolescents in the 10-19 age group diagnosed with celiac disease. Research data were collected by online questionnaires (Google Forms) between January and April 2022. Sociodemographic and disease-related data of adolescents who were compliant and those who were non-compliant with a gluten-free diet during the COVID-19 pandemic were compared.
Celiac disease is a chronic immune-based intestinal pathology. Its prevalence is 1% and its incidence has increased in recent years. This disease usually causes gastrointestinal and/or extraintestinal symptoms, which can only be reduced by following a strict, lifelong gluten-free diet. In addition, the social life of people with celiac disease is impaired due to the impact of the gluten-free diet on daily activities. An adequate Nutrition Education program can improve the physical and social health of these people. Moreover, considering the high impact this disease has on the people close to the celiac patient, and due to the important role that general population has in the care and inclusion of persons with celiac disease, education should be directed to general population. Therefore, the purpose of ZELIAKIDE program is to promote Nutrition Education in general population. In particular, the specific aims are 1) to promote the social inclusion of people with celiac disease by raising awareness among the general population, and 2) to promote a balanced diet and an interest in science and research among children. ZELIAKIDE is an intervention aimed at children and focused on the school environment, and is based on Inquiry Based Learning (IBL) methodology. Inquiry-based Teaching-Learning Sequence (TLS) has been created to internalize and integrate competences related to celiac disease, gluten, gluten-free diet, balanced diet and healthy lifestyle. In addition, this TLS aims to develop scientific competence through activities that promote science and the research process. Although nutrition education programs for children have proven to be effective, it has been observed that children's interest in science has decreased. The investigators therefore aim to implement a nutrition education programme based on previous experiences that promotes science skills and stimulates children's interest in science.
