Active clinical trials for "Celiac Disease"

The study evaluates whether hypothyroid patients requiring elevated doses of levothyroxine to maintain a euthyroid state are at increased risk of having celiac disease. It also attempts to determine if there is a threshold level of levothyroxine needed to maintain a euthyroid state in patients with hypothyroidism that should prompt serologic testing for celiac disease.

The purpose of this study is to determine how well capsule endoscopy identifies changes in the small bowel mucosa of celiac disease patients.

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.

Food allergies are associated with a decrease in quality of life. Patients with FPIES often have more food avoidance than necessary. The greater the number of avoided foods, the greater the risk of eating disorders. To date, no study about quality of life or assessment of eating difficulties has been performed in a French-speaking pediatric population with FPIES or celiac disease

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).

The objective of this study is to determine whether the finger tip images captured by the EPIC ClearView device, when analyzed via the ClearView software, produce a Response Scale that characterizes trends consistent with known diagnoses identified by medical doctors. Specifically, the investigators hypothesize that the organ system involving any of a series of known active diagnoses will be identified in the EPIC ClearView Response Scale report with the intention of providing potential triage capabilities.

This study is to see if a high response to the TTG screening test for celiac disease is as accurate as the current method of diagnosing celiac disease which entails a general anesthetic and upper endoscopy to obtain biopsies of the small intestine. If the screening blood test is highly accurate, then some patients that are being evaluated for celiac disease may not require an upper GI endoscopy and can be treated more quickly. If they respond to the therapy then they will be deemed to have celiac disease.

To study the prevalence and clinical features of celiac disease in children to develop new treatment approaches and rehabilitation strategies.

This is a model development, open label, no therapeutic treatment, three sequential group, short term-gluten challenge study in subjects with celiac disease. Immune responses are evaluated following gluten challenge. Approximately fifteen subjects with celiac disease will be enrolled in up to three sequential groups (5 subjects per group).

The goal of this study is to better understand the symptoms and impacts of celiac disease (CeD). Participants use a smart phone online app to answer daily questionnaires about symptoms and life with CeD for 12 weeks. There are no blood draws, gluten challenges, medications, or doctor visits required.
