Active clinical trials for "Celiac Disease"

Video capsule endoscopy (VCE) is recommended as the gold standard in small bowel exploration. The efficiency of the axial-viewing (Given, Imaging) has been widely reported. The CapsoCam capsule (Capsovision, California, USA) has four cameras allowing the exploration of the small bowel through 360 degree lateral viewing. Celiac disease is the most common autoimmune enteropathy in Western countries, and is usually associated with a good response to the gluten free diet and an excellent prognosis. However, a minority of patients develop complications of the disease, such as refractory celiac disease, ulcerative jejunoileitis and neoplastic complications such as adenocarcinoma of the small bowel and enteropathy associated T cell lymphoma. In recent years, the detection of small bowel lesions has dramatically improved thank to the availability of capsule endoscopy exploration. The aim of this study was to evaluate detection rate and diagnostic concordance of the axial view capsule and CapsoCam capsules in the same patients.

The primary objective is to obtain stool samples from subjects diagnosed with , and displaying signs and/or symptoms of IBD and/or IBS will be evaluated in this study. Eligible subjects require a diagnostic colonoscopy with possible biopsy and clinical evaluation.

This case control study aims to determine whether spontaneous coronary artery dissection (SCAD) is associated with autoimmune diseases and to update the incidence of SCAD in a population-based cohort.

Computer-aided image recognition will improve the technique of endoscopic ultrasound-celiac plexus block/celiac plexus neurolysis (EUS-CPB/CPN) and improved pain relief.

The celiac disease (CD) is a disease with an immune and genetic component that is activated by the presence of gluten, and damages the intestine mucosa and causes malabsorption of food. In the oral environment the investigators see enamel defects and recurrent ulcers. Celiac patients have to keep a restrict gluten-free diet, in order to prevent the clinical symptoms of the disease (such as diarrhea, stomach ache and weight loss). It has been assumed that the patients have less cariogenic diet, and that caries prevalence is not as high as in normal population. In celiac patients the investigators find enamel defects that are characterized with pits and deep fissures and sometimes the complete loss of enamel. These defects are classified by the grading of the CD related DED's (dental enamel defects) according to Aine. These defects are symmetrical defects in the permanent dentition, in teeth that develops at the same time. The cause is thought to be hypocalcaemia or genetic. These defects were found in 42.2% of celiac patients in appose to only 5.4% in healthy population. Recurrent ulcers were found in 41% in the oral cavity of celiac patients, compare to 27% in healthy population. After changing the diet to a gluten-free diet, an improvement is seen in the presence of these ulcers.

The main purpose of this study is to assess the impact of the diagnosis of celiac disease on general health, healthcare resource utilization, quality of life and lifestyle. We hypothesize that diagnosis and subsequent dietary treatment may have positive impact on these variables.

There are no agreed endoscopic signs for the diagnosis of villous atrophy(VA) in coeliac disease(CD), necessitating biopsies and for both diagnosis and exclusion. Here we evaluated the role of near focus Narrow Band Imaging(NF-NBI) for the assessment of villous architecture in suspected CD with development and further validation of a novel NF-NBI classification.

This study series consists of four related studies and aims to explore and describe many important elements of alopecia areata over three key areas: (1) the current epidemiology of alopecia areata, (2) the prevalence and incidence of psychiatric co-morbidities in people with alopecia areata, (3) the prevalence and incidence of autoimmune and atopic conditions in people with alopecia areata, and (4) the incidence of common infections in people with alopecia areata.

Being diagnosed with coeliac disease means that individuals can no longer consume things containing gluten, such as bread or cake, or they can become very ill. This can make situations involving food challenging, such as social situations or lunch at school. The investigators know that being diagnosed with coeliac disease as a teenager can be particularly upsetting and can lead to problems such as anxiety or low mood. Research suggests that when young people are worried about the impact of their condition on their life, they can find it challenging to tell their doctor or ask for support. The investigators would like to understand the experiences of young people with coeliac disease who attend the Paediatric Gastroenterology service at a local children's hospital. The investigators are particularly interested in the reasons why young people either feel able or unable to tell their doctor that they are experiencing difficulties relating to their wellbeing during their appointments, in order to improve support for young people. This study aims to recruit young people between the ages of 11 and 16, who are attending secondary school, to ask them about the things that make it easier or more difficult to share any concerns about their wellbeing with their doctor.

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.
