PRV-015 in Gluten-free Diet Non-responsive Celiac Disease
This study will evaluate the efficacy and safety of PRV-015 in adult patients with non-responsive celiac disease (NRCD) who are on a gluten-free diet (GFD).

Rapid Technique for the Detection of Intestinal Anti-transglutaminase Antibodies
Intestinal Celiac Disease (CD)-antibodies have been described as the best marker to reveal progression toward villous atrophy and could become the diagnostic marker to make prompt diagnosis in the wide clinical spectrum of CD reducing the delay in diagnosis and treatment. The introduction of either anti-endomysial antibodies (EMA) assay or rapid anti-Transglutaminase 2 (TG2) test on supernatant of mechanically lysed biopsy samples in the clinical practice would improve the diagnosis of CD, especially in clinically challenging scenarios. The availability of an accurate test for identifying intestinal CD-antibodies that do not need the...

Response to Different Wheat Genotypes in Not-celiac Wheat Sensitivity
Non-celiac gluten sensitivity (NCGS) is a condition where intestinal and extraintestinal symptoms are triggered by gluten ingestion in the absence of celiac disease and wheat allergy. Despite the great interest in NCGS, much remains unknown about the pathogenesis. Some studies seem to suggest that wheat components other than gluten (i.e. amylase/trypsine inhibitors, ATIs) can cause the symptoms, and therefore the term "non-celiac wheat sensitivity" (NCWS) has been proposed instead of NCGS. It is believed that this condition is worldwide increasing, due to the evolution of wheat breeding (i.e. consumption of wheats with high gluten...

Safety and Efficacy of Fecal Microbiota Transplantation
The gut microbiota is critical to health and functions with a level of complexity comparable to that of an organ system. Dysbiosis, or alterations of this gut microbiota ecology, have been implicated in a number of disease states. Fecal microbiota transplantation (FMT), defined as infusion of feces from healthy donors to affected subjects, is a method to restore a balanced gut microbiota and has attracted great interest in recent years due to its efficacy and ease of use. FMT is now recommended as the most effective therapy for CDI not responding to standard therapies. Recent studies have suggested that dysbiosis is associated with...

Study of the Safety, Tolerability, Pharmacokinetics and Biomarker of DONQ52 in Celiac Disease Patients
This study is to characterize the safety and tolerability of an investigational drug called DONQ52 and consists of a single ascending dose part (Part A) and a multiple ascending dose part (Part B) in well-controlled celiac disease patients.

Supplementation With B. Infantis for Mitigation of Type 1 Diabetes Autoimmunity
Investigator initiated, randomised, placebo-controlled, double-blind, multi-centre primary intervention study to assess whether daily administration of B. infantis EVC001 from age 7 days to 6 weeks (+14 days) until age 12 months (+ 14 days) to children with elevated genetic risk for type 1 diabetes reduces the cumulative incidence of beta-cell autoantibodies in childhood.

Systems Biology of Gastrointestinal and Related Diseases
This is a longitudinal observational study on patients with gastrointestinal and related disease. The study will be conducted for at least 10 years, following each participant over time, as they either go through relapses and remissions, or progression of their disease.

T Cell Receptor (TCR) Sequencing and Transcriptional Profiling in Adult Celiac Disease Patients Undergoing Gluten Challenge
The primary objectives are: - Characterize the T cell receptor (TCR) repertoire in duodenal biopsy samples of participants pre- and post-challenge. - Compare for each patient the TCR repertoire of duodenal biopsy samples with the peripheral blood TCR repertoire of each study participant - Characterize the transcriptome of duodenal biopsy samples and blood from study participants pre- and post-challenge The secondary objectives are: - Ex vivo identification and validation of DQ-restricted gliadin specific TCRs. - Characterize the gluten-challenge induced changes in small...

The Effect of Gluten-free Diet on Parkinsonism
Recent data suggest that the brain-gut axis, chronic intestinal inflammation and microbiome may contribute to the pathogenesis of neurodegenerative diseases with alfa-synucleinopathy, which include Parkinson's disease (PD) and Multiple system atrophy (MSA). Environmental factors e.g. diets, microbiome, metabolites and immune mechanisms may play important role in pathogenesis of these diseases. In the human arm of this project, the investigators will address effects of an anti-inflammatory gluten-free diet (GFD) on motor and non-motor symptoms as well as its effects on immune and metabolomic characteristics in patients with PD and...

Tissue Destruction and Healing in Celiac Disease
The purpose of this clinical study is to learn more about celiac disease pathogenesis and clinical symptoms. In particular, this study will examine the interactions between biological factors such as, intestinal epithelial cells, microbiota, immune system, genetics, and gluten and their effect on celiac disease clinical symptoms, and severity of tissue destruction and its ability to heal in individuals with celiac disease. Information collected in the study will help researchers to generate better resources to advance celiac disease patient care.
