NCT ID: NCT02745457 Recruiting - Crohn's Disease Clinical Trials

Body Composition in Children With Inflammatory Bowel Disease

Start date: April 2016
Phase: N/A
Study type: Observational

Background: Growth impairment is commonly seen in children diagnosed with inflammatory bowel diseases (IBD), mainly those with Crohn's disease (CD). There is general consensus in the literature that body composition, composed of fat mass and lean mass is altered in children with IBD compared with controls. Evidence regarding the effect of different therapeutic approaches on body composition in children with IBD is scarce and inconsistent. Furthermore, most studies used anthropometric measures and dual energy X-ray absorptiometry (DEXA) for body composition assessment, while information on the usefulness of air displacement plethysmography (ADP) for this assessment is lacking. Objectives: To assess body composition in children with IBD by ADP and DEXA at diagnosis and at various intervals during follow up. Design: A prospective cohort study. Setting: Pediatric gastroenterology institute, Schneider Children's Hospital. Participants: Children 6 year to 17 years who are diagnosed with either CD or ulcerative colitis (UC). Main outcome measures: Accuracy of ADP in comparison to DEXA and percentage of fat mass and lean mass at diagnosis and during treatment. Secondary outcome measures: Correlation of body composition to skin fold, mid arm circumference measurements, BMI, inflammatory markers, gender, disease activity and physical activity.

NCT ID: NCT02742597 Recruiting - Hypertension Clinical Trials

Patient-Centred Innovations for Persons With Multimorbidity - Ontario

PACEinMM-ON
Start date: January 2016
Phase: N/A
Study type: Interventional

The aim of Patient-Centred Innovations for Persons With Multimorbidity (PACE in MM) study is to reorient the health care system from a single disease focus to a multimorbidity focus; centre on not only disease but also the patient in context; and realign the health care system from separate silos to coordinated collaborations in care. PACE in MM will propose multifaceted innovations in Chronic Disease Prevention and Management (CDPM) that will be grounded in current realities (i.e. Chronic Care Models including Self-Management Programs), that are linked to Primary Care (PC) reform efforts. The study will build on this firm foundation, will design and test promising innovations and will achieve transformation by creating structures to sustain relationships among researchers, decision-makers, practitioners, and patients. The Team will conduct inter-jurisdictional comparisons and is mainly a Quebec (QC) - Ontario (ON) collaboration with participation from 4 other provinces: British Columbia (BC); Manitoba (MB); Nova Scotia (NS); and New Brunswick (NB). The Team's objectives are: 1) to identify factors responsible for success or failure of current CDPM programs linked to the PC reform, by conducting a realist synthesis of their quantitative and qualitative evaluations; 2) to transform consenting CDPM programs identified in Objective 1, by aligning them to promising interventions on patient-centred care for multimorbidity patients, and to test these new innovations' in at least two jurisdictions and compare among jurisdictions; and 3) to foster the scaling-up of innovations informed by Objective 1 and tested/proven in Objective 2, and to conduct research on different approaches to scaling-up. This registration for Clinical Trials only pertains to Objective 2 of the study.

NCT ID: NCT02735941 Not yet recruiting - Crohn's Disease Clinical Trials

Study on Cannabinoid Receptor Expression in Gastrointestinal Diseases

Start date: April 2016
Phase: N/A
Study type: Observational

The purpose of the study is to investigate phospholipid ligands and their receptors in inflammatory bowel diseases and colon cancer. Several new species of lipids have been recently discovered which are able to transmit information to cancer cells in the large intestine. The lipids and their responsive receptors build an axis that is thought to influence the development of inflammation and cancer.

Pilot Study of Fecal Transplantation Using a Unique Diet for Donor and Recipient in Moderate to Severe Treatment Refractory Colitis in Inflammatory Bowel Disease

Start date: November 2016
Phase: Phase 4
Study type: Interventional

Changing the microbiota has become the most intriguing target for intervention in inflammatory bowel disease (IBD). Dietary therapy is successful in mild to moderate Crohn's disease and may be effective in mild to moderate ulcerative colitis (UC) as well, though dietary interventions in UC are just getting underway. However these interventions are less likely to be effective for the more severely inflamed or refractory end of the spectrum. Fecal transplantation (FT) has been suggested as a method to treat refractory IBD, but most studies have been unsuccessful in establishing remission and especially prolonged remission. The investigators hypothesize that this is due to selection of random donors and the inability to maintain an optimal microbiota eco system post transplant. Diet is a powerful tool to modulate the microbiota. The investigators propose to modify FT using a novel protocol and approach that we have developed. We have developed a unique diet that is geared to rectify dysbiosis in UC and damage to the mucous layer in active UC. The investigators intend to condition both donor and recipient with the diet to achieve optimal conditions for transplant to succeed for both donor and recipient .The investigators intend to evaluate this protocol in adults with active UC that are refractory to medications. The investigators will start with a randomized controlled trial involving 76 subjects, however in the first pilot stage The investigators will enroll 34 patients, and extend the study if there is a trend for better outcomes with the dietary conditioning protocol. Furthermore, The investigators hope to identify successful donors during this period to use during the study extension.

NCT ID: NCT02729233 Not yet recruiting - Ulcerative Colitis Clinical Trials

Predicting Clinical Response to Golimumab With Mucosal Barrier Dysfunction

Start date: May 2016
Phase: N/A
Study type: Interventional

Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease (IBD). UC is an ongoing disease of the colon or large intestine. Studies have shown that leakiness of the gut plays a major role in the development of UC. Leakiness of the gut is a condition that is a result of damage to the intestinal lining, making it less able to protect its internal environment as well as to filter needed nutrients and other substances. Some bacteria, toxins, and waste not normally absorbed may get into the blood stream. Golimumab is an FDA approved medication used for the treatment of moderate to severe ulcerative colitis. The investigators have evidence to suggest that measuring the leakiness of the gut using a tool called a confocal laser endomicroscope may be able to predict how well a patient's body will respond to treatment of UC with golimumab. Confocal laser endomicroscopy (CLE) is an FDA approved technique that can look at the cells of a patient's gut during colonoscopy to assess the leakiness of gut. The objective of this study is to determine how the leakiness of the gut in patients with UC can predict response to golimumab therapy.

NCT ID: NCT02721823 Not yet recruiting - Ulcerative Colitis Clinical Trials

Randomized Controlled Trial of Stress Reduction and Lifestyle Modification for Ulcerative Colitis

MBMCol
Start date: March 2016
Phase: N/A
Study type: Interventional

Patients with ulcerative colitis often suffer significant limitations to their quality of life, which are also conditioned by particular stress and psychosocial accompanying symptoms of the disease. A multimodal program for stress-reduction and lifestyle-modification has been shown to be effective in promoting the quality of life. The study will examine the promotion of the quality of life of patients with ulcerative colitis and the positive Influence on stress, psychological symptoms and physiological parameters. 92 patients with ulcerative colitis will be randomized in an Intervention group and a control group for 10 weeks. The primary outcome is the disease-specific quality of life, the secondary outcomes are stress, psychological symptoms, inflammatory parameters, disease activity parameters, bowel parameter and the microbiome.

The Role of CD4+ T Cell Subsets in the Mechanism of Action of Vedolizumab in Ulcerative Colitis

Start date: May 2016
Phase: N/A
Study type: Observational

The cause of Inflammatory Bowl Disease (IBD) is not known, but studies from patients with IBD have found that these patients make unusually strong immune responses to their own intestinal tissues and to bacteria that normally live in the healthy gut. These overactive immune responses might result from an imbalance of T-lymphocytes, which are a type of white blood cell that recognize and respond to threats like infection or damaged tissues. In healthy tissues, a type of T-lymphocytes called T-regulatory cells control excess inflammation by preventing other T cells, called T-effector cells from responding. We believe that T-regulatory cells are somehow less active in IBD, resulting in damage to intestinal tissues by the T-effector cells. T-lymphocytes, including both T-regulatory and T-effector cells, are guided to different parts of the body by 'alpha4beta7-integrin' molecules. Vedolizumab or Entyvio works by blocking this homing molecule so that T cells do not reach the intestine, but stay in the blood where they cannot aggravate your IBD. This study will help in understanding how Vedolizumab helps to heal or decrease the symptoms of your Ulcerative Colitis. The effect of Vedolizumab on different types of T cells in the human intestine has not yet been studied. However, the investigators think that Vedolizumab will shift the balance of T cells in the intestine towards more healing T-regulatory cells and less damaging T-effector cells. The purpose of this study is to measure the different types of T cells in participants' blood and intestinal tissue before and during Vedolizumab treatment.

NCT ID: NCT02693730 Recruiting - Ulcerative Colitis Clinical Trials

Phenotyping IBS: Perceptions and Modulations of Visceral Sensations

PMVS-P
Start date: January 2016
Phase: N/A
Study type: Observational

The purpose of this research study is to improve the understanding of irritable bowel syndrome (IBS) and its underlying cause. The investigators will use magnetic resonance imaging (MRI) to observe differences in the brain between people diagnosed with IBS compared to healthy controls and people with ulcerative colitis, a disease group that has already been characterized. By doing this correlative and comparative study, the investigators hope to gain knowledge on IBS in order to keep the field moving in the right direction and becoming one step closer to discovering effective treatments.
