Active clinical trials for "Crohn Disease"

This study aims to assess the effectiveness (specificity and sensitivity) of using magnetic resonance enterography (MRE) as a screening tool for axial spondyloarthritis (axSpA) in patients with Crohns disease. Patients with evidence of axSpA on MRE imaging will be assessed clinically for axSpA (including a dedicated axial magnetic resonance imaging scan of the spine and sacroiliac joints) and will be compared to a group of age and sex-matched control participants with Crohn's disease but with no evidence of axSpA on MRE imaging.

The main purpose of this study is to assess ustekinumab's ability to induce clinical response and remission ("effectiveness") at Week 16 and remission at Week 52 and Week 104 in participants with Crohn's disease (CD). Response and remission will be assessed using clinical parameters. Retention rate at week 52 and 104 will also be studied.

Crohn's disease (CD) is a lifelong condition of inflammation in the bowel. CD can affect any part of the gastrointestinal tract from mouth to anus. Symptoms can include: tiredness, stomach pain, diarrhea (which may be bloody if the disease is severe), fever, weight loss, skin rashes, arthritis and inflammation of the eye. Infliximab-IFX (Remicade®) is a medication that is used to treat CD in adults and children. In adults it has been shown that the amount of this drug a person has in their blood can show how well it is working for them. Health Canada has approved Infliximab -IFX for the treatment of CD in children 9 and older. In Canada, doctors may prescribe Inflixmab to younger children when other therapies do not resolve their disease symptoms. This is called "off-label" use of Infliximab. IFX levels in the body and consequently its efficacy can be influenced by many biological characteristics within the patient's body. In about 17% of those treated with IFX, the patient's immune response against IFX may lead to a three to fivefold increased risk of loss of response. This immune response to the medication often occurs when drug levels are undetectable in the body. Thus it is in order to achieve best results with this treatment, physicians need to be able to adjust dosing specific to each patient. A recent study has shown that 29% of children have an undetectable IFX level at the 4th medication infusion. Up to 40% of patients receiving scheduled IFX have undetectable drug level prior to their next infusion. In order to minimize the loss of response, we hope to conduct an observational cohort study of pediatric patients treated with IFX. This open label, cohort study aims to: Determine the pharmacokinetics of IFX in children with CD and the factors that affect IFX levels during the first three loading infusions Obtain data to create a model that can guide and adjust the IFX dose and frequency to achieve optimal trough level between 5 and 10 ug /ml at 14 weeks.

This study highlight genetics mutations with major effect in Crohn's Disease (CD) by WES in individuals affected and healthy individuals from EPIMAD Inserm InVS registry families.

To idetify the factors favoring the use of enteral nutrition would be helpful to select preferred patients suitable for enteral nutrition.

The purpose of this study is to assess the effectiveness of ustekinumab on extra-intestinal manifestations (EIMs) and immune-mediated inflammatory diseases (IMIDs) associated with inflammatory bowel disease (IBD) (both Crohn's Disease [CD] and Ulcerative Colitis [UC]).

Good nutritional status of patients with Crohn's disease (CD) is associated with better outcome of the disease and better health-related quality of life. The prevalence of malnutrition in patients with Crohn's disease varies and is higher in patients with active disease. Available studies in the literature have assessed the nutritional status of patients with Crohn's disease. However, sample size of available studies is small and highly heterogeneous, and most patients are hospitalized with active disease. The aim of the present study is a thorough assessment of nutritional status of 250 patients either with active Crohn's disease or in remission of the disease using multiple widely available tools and methods, in order to assess their accuracy and estimate the prevalence of multiple malnutrition phenotypes such as undernutrition, sarcopenia, sarcopenic obesity and cachexia as well as overweight and obesity. Finally, the effect of the nutritional status on the course of the disease will be investigated.

The purpose of post-marketing surveillance (PMS) is to assess the safety and effectiveness of ustekinumab (Stelara) for Crohn's disease participants under real world clinical practice.

The Manitoba Inflammatory Bowel Disease (IBD) Cohort Study participants were drawn from a population-based research registry. The cohort consisted of 388 adult enrollees with recent IBD onset who completed the baseline survey and interview in 2002 to 2003. Participants were followed every 6 months with surveys and annually with interviews. Diagnosis and disease type were verified by chart review.
