Filter by:Previous studies have showed that Coeliac Disease (CD) prevalence is significantly higher in children compared with adults. The largest epidemiologic study carried out in Spain to date (n=4230) reported a higher CD prevalence in children (1:71) than in adults (1:357) during 2004-2007. To study whether this difference was due to environmental factors influencing infancy or the development of gluten tolerance with age, a natural history study in pediatric age was initiated in 2013. Unexpectedly, the prevalence in children of 1-2 years of age was lower (1:135) than the previously reported in 2004-2007 for that age group (1:25). During follow-up, 1/3 of the asymptomatic cases showed reversion of the intestinal lesion and/or negativization of CD serological markers while continuing on a gluten-containing diet. Therefore, the development of gluten tolerance seems to have a major effect in age-related differences in CD prevalence. However, gluten tolerance phenomenon does not explain the differences found between the 2013-2019 and the 2004-2007 cohorts, suggesting that environmental factors may contribute as well. Apart from genetic factors, several environmental factors are believed to influence disease appearance, such as the time that gluten is introduced to the diet, viral infections, type of birth, antibiotic treatments, etc. Therefore, development of tolerance and environmental factors seem to equally play an important role in age-related differences in CD prevalence. However, more data is needed in order to know how environmental factors influence disease prevalence in Spain. Also, the previous studies carried in Spain were performed in specific geographical areas: Asturias, Basque Country and Catalonia using slightly different methodology and focused on different age groups, thus making results comparison and global extrapolation challenging. In this study, the investigators aim to determine global CD prevalence in Spain during 2020-2021 and: 1) compare it with the results obtained in previous studies; and 2) identify whether there are any differences associated with age, environmental factors and/or geographical area. For this purpose: a) participants are recruited based on the reference population regarding age and gender; b) recruitment is done in 5 different geographical areas in Spain: Andalusia, Asturias, Basque Country, Catalonia and Madrid; c) relevant clinical, social and environmental data is collected and d) serologic screening (anti-tissue transglutaminase (tTG) - Immunoglobulin A (IgA) antibodies detection in blood serum) with histological confirmation (small-intestinal biopsy) is used to detect CD cases and determine disease prevalence.
Aims of this study are to evaluate adolescents with celiac disease during their transition from pediatrics to adult care, and to develop better healthcare follow-up practices.
The primary aim of the study is to detect the presence of gluten immunogenic peptides (GIP) in urine samples from celiac patients on a gluten-free diet clinically responsive and non-responsive to dietary treatment and from suspected celiac patients already on a gluten-free diet.
Celiac disease (CD) is an immunological disorder that mainly affects the small intestine, generating an inflammatory process in response to the presence of gluten (a protein). Autoimmune diseases are part of a group of diseases that are difficult to diagnose without a specific protocol or consensus to detect them due to the number of symptoms and diseases with which it has a relationship. The incidence of CD in Spain -according to data from the rest of the European Economic Community, since there is no study on incidence in Spain- is assumed to be approximately 1 per 100 live births. It is more frequent in women, with a 2:1 ratio. The only treatment consists of a STRICT GLUTEN-FREE DIET FOR LIFE. This results in the disappearance of symptoms, normalization of serology and recovery of intestinal villi. Failure to follow the diet can lead to important complications which, especially in adulthood, can manifest themselves in the form of osteopenia, osteoporosis and a high risk of neoplasms in the digestive tract, mainly. The main objective is to achieve a physical and physiological improvement in menopausal or post-menopausal celiac women. The specific objectives will be to know the influence of a dietary-nutritional program combined with physical exercise in menopausal or post-menopausal celiac women on: - Physical condition (strength, endurance, functional autonomy...). - Body composition. - Psychological aspects. - Physiological parameters (heart rate, maximum oxygen consumption, blood analysis...).
To assess the prevalence of renal disease in a pediatric population of patients with celiac disease by looking for the presence of hematuria and/or proteinuria.
This is an observational study, in which newborn infants from the general population are screened at birth for HLA-conferred susceptibility to type 1 diabetes and celiac disease. The participants carrying genetic susceptibility to type 1 diabetes (approximately 9.5%) will be analyzed for diabetes-associated autoantibodies at the age of 1, 2 and 3 years, while those predisposed to celiac disease (about 14%) will be screened for tissue transglutaminase antibodies at the age of 1 and 3 years. The intention is to screen annually 10,400 newborn infants for a period of 3 years. About 988 infants are each year identified as a child at risk for type 1 diabetes, and it is expected that around 80% of the families with such a child are willing to join the autoantibody screening. Approximately 1456 infants are each year recognized as a child at risk for celiac disease, and again the expectation is that 80% of the families will join the antibody screening program.
The main aim of the study is to currently define the prevalence of celiac disease (CD) in children aged 5-10 years in 2 Italian cities (Ancona and Verona). The screening protocol is based on a 1st line genetic test (searche of HLA DQ2/DQ8 genotypes) followed by a serological diagnosis (IgA TTG and IgG DGP).
This is a phase 2, single-center prospective, double-blind, placebo-controlled, crossover study in Type 1 diabetes and celiac disease subjects attempting a GFD for at least one year prior to screening.
The investigators will see if the drug teriflunomide (which is in use in other immune disorder (multiple sclerosis)) can inhibit the immune activation in celiac disease patients during a 3 day gluten challenge. This will be measured in a blood sample.
This study aims to describe the prevalence of additional autoimmune diseases and their specific antibodies at type 1 diabetes (T1D) diagnosis, and their incidence rate during follow-up, for children and adolescents. It also aims to describe the characteristics of the pediatric cohort followed since 2014 for type 1 diabetes by one of France's centers of reference for paediatric diabetes.
