View clinical trials related to Celiac Disease.
Filter by:Background: Celiac disease is an immune-mediated reaction to gluten, presenting with diarrhea, weight loss, abdominal complaints and a range of less common associated neurologic and psychiatric symptoms. Evidence of a link between schizophrenia and celiac disease dates back to 1961. Recent evidence shows that 5.5% (age adjusted) of persons with schizophrenia participating in the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study had a level of antibodies to tTG that is consistent with a diagnosis of celiac disease (compared to 1.1% of the comparison sample). An unexpected finding was that 23.4% (age adjusted) of the CATIE sample had antibodies to gliadin (compared to 2.9% of the comparison sample). It is hypothesized that a gluten free diet in people with schizophrenia who have Celiac disease or gluten sensitivity will have improvement in symptoms and quality of life. Objectives: The aim of this proposed pilot study is to establish the feasibility of a initiating and maintaining a Gluten-free diet in these two groups. For this study The investigators will identify 8 individuals who have positive assays to tTG antibodies and confirmed celiac disease (N=4), or positive assays for anti-gliadin antibodies (N=4). The investigators plan to consent at least 2 subjects from each group and ask them to participate in a two-week open label treatment of a gluten free diet. The groups are; 1. Celiac disease (positive tTG antibody); and 2. Positive assay on Antigliadin antibodies
The purpose of this study is to monitor of gluten-free diet compliance in celiac patients by assessment of gliadin 33-mer equivalent epitopes in feces.
The goal of this research is to conduct a pilot clinical study to image Celiac disease characteristic mucosal lesions and compare Optical Frequency Domain Imaging (OFDI) images to histologic evaluation in children, adolescents and young adults with suspected Celiac disease.
A randomized, double-blind, placebo-controlled Phase 2B study to evaluate the efficacy and safety of Larazotide Acetate in the treatment of patients with celiac disease who have persistent symptoms despite being on a gluten-free diet.
The small bowel biopsy is the cornerstone of for the diagnosis of celiac disease. In addition to being the gold standard for the initial diagnosis of celiac disease, periodic biopsies are also recommended on an ongoing basis for this life-long disease. However, biopsy evaluation is invasive and expensive. Therefore, there is a need for simple, non-invasive tests that can be performed on celiac patients with subclinical disease. The present study is based on the hypothesis that the expression and activity of cytochrome P450 CYP3A4 in the small intestinal mucosa is a sensitive measure of enteropathy. Therefore small intestinal CYP3A4 activity will be markedly different in celiac disease patients with active disease as compared to patients in remission. Small intestinal CYP3A4 activity will be measured in three ways: (i) Cmax of oral simvastatin, a widely used drug that is predominantly metabolized by small intestinal CYP3A4; (ii) AUC of oral simvastatin; and (iii) Measurement of CYP3A4 activity in two small bowel biopsies.
Direct benefits to the participants, who are diagnosed with celiac disease may be substantial and could include lessening or prevention of GI symptoms, correction of biochemical abnormalities and reduction in risk for malignancies or bone disease which are most common in untreated celiac disease. However, the precise benefit is unknown and the motivation for this proposed study. If these individuals have a positive celiac serology test at the present time there is a high likelihood that they may have celiac disease.
This exploratory study has been designed to determine the effect of the probiotic Bifidobacterium infantis vs. placebo orally administered over a period of 3 weeks on clinical features, Quality of Life parameters (QoL), intestinal permeability and inflammatory markers of patients having positive serological evidences of Celiac Disease.
A phase 2a study to evaluate the safety and efficacy of ALV003 to treat celiac disease.
The focus of this study is to create a database containing information about patients with celiac disease. This database will allow us to examine clinical and epidemiologic features of the University of Chicago Medical Center patient population. We have the largest population of patients with celiac disease in the mid-West and as such this study using information gathered from our database can greatly contribute to our current understanding of this disease.
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.
