Efficacy of a Gluten-free Diet in Difficult to Manage Nephrotic Syndrome: Utility of Plasma Zonulin Levels as a Predictive Biomarker
Elevated plasma zonulin levels, which are supportive of a diagnosis of CD (celiac disease) in children with gastrointestinal symptoms, may indicate patients with difficult-to-manage NS who will benefit from initiation of a GFD (gluten free diet). This pilot study will determine whether high plasma zonulin levels can be used as a screening tool to identify patients with NS (nephrotic syndrome) who are likely to demonstrate a beneficial response to a GFD. It will provide important information about the feasibility of testing the efficacy of a GFD for this condition and assist in the design and sample size calculation for a definitive trial to test ...
Endoscopic Ultrasound-Guided Celiac Plexus Neurolysis (EUS-CPN) for Chronic Pancreatitis
Physicians need a tracking system for specific treatment modalities, and data to determine the impact of endoscopic ultrasound pain management for patients with chronic pancreatitis.
EUS-guided Celiac Plexus Neurolysis for the Treatment of Abdominal Pain in Pancreatic Cancer
Studies have shown that injecting local anesthetics in areas rich in blood vessels increases the risk of drug injection into blood vessels by mistake and increases the systemic absorption of drugs, which may increase the incidence of central nervous system and cardiovascular system toxic events caused by local anesthetics.EUS-CPN-related complications have not been clearly associated with local anesthetic adverse events.However, EUS-CPN local anesthetic injection area is located around the beginning of the abdominal trunk with abundant large and small blood vessels. The choice of local anesthetics with higher safety than bupivacaine, such...
Experiences of Disclosure in Adolescents With Coeliac Disease
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...
Fluorescence Spectroscopy for Gut Permeability Assessment
This research aims to develop portable devices - known as fluorescence spectrometers - to monitor the leakage of fluorescent dyes out of the gut into the blood stream. These devices will measure the leakiness (permeability) of the gut in a non-invasive manner and will provide an early warning that patients are at risk of infections caused by the unwanted flow of bacteria from the intestine to the rest of the body.
Genomic Resources for Enhancing Available Therapies (GREAT1.0) Study
This is a prospective, descriptive, observational research study designed to observe and document the clinical practice by domain experts, and how the knowledge of new findings that are published in the medical literature affect clinical decision making. The study will evaluate risk factors and co-variants, including genetic variants that are associated with disease progression such as pain, inflammation, organ dysfunction, disability and quality of life.
Gluten Challenge in Celiac Disease
Up till 30 participants with celiac disease on a glutenfree diet are asked to consume gluten containing cookies or bread for 3 days. Questionnaires and sampling of blood is done before, during and after.
Gluten Challenge Study in Celiac Disease Participants (MK-0000-402)
This is a gluten challenge study to characterize peripheral blood and intestinal gluten specific cluster of differentiation 4 glycoprotein (CD4+) thymus lymphocyte (T cell) subsets in participants with Celiac Disease
Gluten Free Diet in IBS
Patients with irritable bowel syndrome (IBS) often benefit from dietary changes. The effect of a gluten-free diet (GFD) on clinical symptom improvement and psychological well-being will be checked in patients with IBS. In addition, the stimulatory potential of gluten on peripheral blood monocytes will be determined. Responders will be provoked with gluten containing bars or placebo bars to confirm the diagnosis of non-celiac glutensenstitivity.
Gluten-free Oats and Gastrointestinal Health in Coeliac Disease, Part 1
The research aims to investigate the effects of gluten-free oats to the gastrointestinal health in celiac disease patients and healthy subjects. The effects of gluten-free oats on the several intestinal parameters, on the composition of the gut microbiota as well as on the metabolic profile of celiac patients and healthy controls will be studied. The study is divided into two parts. Part 1 will be conducted as a double-blind, randomized and placebo-controlled cross-over study. Healthy subjects will be recruited to the study. The aim is to recruit 15 participants for the part 1. The study will be conducted with a cross-over setting, where...
