Evaluation of the Diagnostic Potential of Artificial Intelligence-assisted Fecal Microbiome Testing...
Inflammatory Bowel DiseasesMicrobiota1 moreThe goal of this clinical trial is to evaluate the diagnostic potential of Artificial Intelligence-assisted Fecal Microbiome Testing for the diagnosis of inflammatory bowel disease. The main question it aims to answer is: • Is Artificial Intelligence-assisted Fecal Microbiome Testing a reliable screening test for inflammatory bowel disease? Participants will be asked to provide fecal samples to be analyzed with next-generation sequencing techniques. If there is a comparison group: Researchers will compare the diagnostic performance of AI-assisted Fecal Microbiome Testing with colonoscopy to see the correlation between the results of both interventions.
Multimodal Ultrasound in Inflammatory Bowel Diseases
Inflammatory Bowel DiseasesThe role of intestinal ultrasound in treatment monitoring has recently gained increasing interest thanks to its non-invasiveness, cost-effectiveness and largely availability. Moreover, new ultrasonographic tools, particularly dynamic contrast-enhanced ultrasound (D-CEUS) and shear wave elastography (SWE) can provide further useful information, such as a quantitative estimation of bowel intramural microvacularization and tissue stiffness. Aim of this study is to evaluate the role of D-CEUS and SWE in predicting deep remission at 12 months from treatment induction in IBD.
Tight Control Management in Perianal Crohn's Disease
Inflammatory Bowel DiseasesPerianal FistulaPerianal Crohn's disease (pCD) affects around one-third of patients with Crohn's disease (CD) during their disease course. It represents a distinct disease phenotype and causes significant morbidity, often requiring multiple surgical interventions. However, treatment of pCD is still challenging and unsatisfactory. Only approximately one-third of pCD patients responded to biologic treatment. Overall, medical therapy with anti-TNF could only achieve prolonged remission in 30-40% of pCD cases. At the same time, surgical treatment could only lead to a favourable outcome in around 50% of patients with a higher recurrence rate in patients with complex than in simple fistulae. Recently, combination of optimal medical therapy with surgical therapy (drainage of sepsis and insertion of seton), with radiological guidance, has been suggested as the standard management so as to improve the outcomes of complex pCD. Magnetic resonance imaging (MRI) is considered to be the gold standard imaging technique for perianal CD. It can visualise the anal sphincter and the pelvic floor muscles, as well as the fistula tracts and abscesses. Previous studies using MRI to monitor treatment response to anti-TNF revealed that radiological healing lagged behind clinical remission by a median of 12 months and that long-term maintenance therapy is probably required to prevent recurrence despite a clinically healed external opening. Therefore, we hypothesize that serial monitoring with MRI is important. Recently, there has been some advance in the surgical treatment of perianal Crohn's disease. FiLaCTM uses a radial-emitting disposable laser fibre for endofistular therapy. Recent systemic review and meta-analysis showed that the primary success rate was 73.3% (11/15) in patients with perianal Crohn's fistula. There has been breakthrough in the management of luminal Crohn's disease. The CALM study has showed that timely escalation of anti-TNF on the basis of clinical symptoms combined with biomarkers in patients with luminal Crohn's disease resulted in better clinical and endoscopic outcomes than symptom-driven decision alone. It is unsure whether this approach is also applicable to patients with perianal Crohn's disease.
Peer Mentoring to Improve Self-management in Youth With IBD
Pediatric Crohns DiseasePediatric Ulcerative Colitis1 moreThis study is a multi-site randomized controlled clinical trial evaluating the efficacy of a peer mentoring program for improving the self-management of youth with IBD. The primary outcomes are youth QOL and functioning in typical life activities. Secondary outcomes are disease outcomes, including disease severity and clinical outcomes (hospital admissions, clinic appointments, missed appointments, procedures). Mentor and parent QOL will also be assessed as secondary outcomes. Mechanisms that may contribute to the effects of the Mentoring Program will be investigated: Parent and child self-efficacy, illness uncertainty, coping, social support and child perceived stigma. Sex will be explored as a moderator. A total of 200 youth and their parents and 100 mentors will be enrolled. Eligibility criteria for youth include age 10-17 years, parent and child English fluency, and no documented neurodevelopmental disorder or history of hospitalization for a psychiatric or behavioral disorder. Mentors will be ≥16 years, ≥1 year post-diagnosis of IBD and managing their IBD well. They will be rigorously screened via online application, interview, checks of references, driving records, and social media, background check, and successful completion of a 3-hour training. Youth will be randomly assigned to the Mentoring Program or an "Educational Activity" comparison group, with baseline assessments occurring prior to randomization. Follow-up assessments will occur post-intervention and 6 months later. The Mentoring Program consists of year-long, 1:1 mentee-mentor relationships with group educational activities, online educational information, and a parent support component. Mentors and mentees are expected to have weekly contact (e.g., text, phone), with in-person contact 1 - 2 times per month. Group activities target self-management skills through experiential opportunities, modeling, and direct instruction. Educational topics include nutrition, stress, IBD and school, and disease management, and are taught by experts in each content area. They also provide opportunities to socialize with other mentors and mentees: lunch and games are provided before or after the educational event. The Educational Activity comparison group consists of separate educational group events on the same topics (with no social time), educational information posted online, and monthly encouragement to engage in activities in the community.
Study of Dietary Composition in Crohn's Disease
Inflammatory Bowel DiseasesCrohn DiseasePatients with inflammatory bowel disease (IBD) often have narrowed microbial diversity and altered composition and function of the gut microbiome. We anticipate the anti-inflammatory diet, when compared with the usual diet, to produce favorable changes in these multi-omics profiles. These findings will provide insight into the interactions between diet and host biology, while providing clues on the mechanisms of diet therapy's effect and CD pathogenesis.
Translating Scientific Evidence Into Practice Using Digital Medicine and Electronic Patient Reported...
Inflammatory Bowel Disease (IBD)Delivery of healthcare has been traditionally limited to in-person visits or hospitalizations, while patients spend the majority of their time at home or work. Digital Medicine (e.g. apps, remote monitoring, telemedicine, patient reported outcomes) has the potential to bridge this gap, but the question remains as to how to translate it to mainstream practice while providing individualized recommendations to improve population health across organizations. Through the creation of a Digital Transformation Network (DTN) for Inflammatory Bowel Disease (IBD), the study team plans to reduce digital disparities and scientifically test the impact of these technologies in a clinical trial in three CTSA sites catering to diverse populations and communities.
Postoperative Extended Venous Thromboprophylaxis in Inflammatory Bowel Disease
IBDVenous Thromboembolism4 moreInflammatory bowel disease (IBD) is a relatively common disease that effects all age groups and carries significant morbidity and mortality. The initial treatment typically involves both short and long term medication, however when this is not enough to adequately control the disease, surgery is often required. The high morbidity and mortality rates are in part due to the increased rates of venous thromboembolism (VTE) such as deep vein thrombosis (DVT) or pulmonary embolism (PE) which have been shown to develop more frequently in IBD patients compared to the general population. Undergoing abdominal surgery has also been shown to independently increase rates of DVT and PE and since the majority of patients with IBD will undergo surgery at least once in their lifetime, the relative increased risk of developing a VTE is very high. The majority of DVT and PE events in the postoperative IBD population will occur after discharge from hospital and therefore carries significant morbidity and mortality risk in a unmonitored setting. Several studies have demonstrated the benefits and safety of twice daily dosing of oral extended VTE prophylaxis agents in orthopedic and cancer postoperative patients following discharge from hospital. There have been no randomized studies which have evaluated the use of extended postoperative VTE prophylaxis in IBD patients. The purpose of this randomized placebo controlled pilot trial will be to evaluate the efficacy and safety of postoperative VTE prophylaxis in IBD patients following abdominal surgery. If this pilot trial demonstrates efficacy in reducing postoperative DVT and PE rates, safety and feasibility, clinicians will be armed with the knowledge to pursue a larger multicenter randomized trial with the intent of reducing overall morbidity and mortality in this high risk population.
Predicting Response to Iron Supplementation in Patients With Active Inflammatory Bowel Disease
Inflammatory Bowel DiseasesIron-deficiency1 moreIron deficiency anemia is the most common systemic manifestation of Inflammatory Bowel Diseases (IBD)-Crohn's disease and ulcerative colitis. Iron deficiency with or without anemia poses a diagnostic and therapeutic challenge due to chronic gastrointestinal blood loss and the inflammatory nature of IBD. Recent illumination of iron metabolism has brought attention to the systemic iron regulator-hepcidin, a peptide hormone that regulates intestinal iron absorption and systemic iron availability. Elevated hepcidin is associated with oral iron malabsorption in IBD. This study aims to evaluate whether hepcidin concentration at baseline can predict response to oral and intravenous iron therapy in patients with IBD and concomitant iron deficiency with or without anemia.
IBD Neoplasia Surveillance RCT
Colonic NeoplasmsInflammatory Bowel Diseases1 moreWe will conduct a multicenter, parallel-group, non-inferiority RCT in persons with IBD undergoing colorectal neoplasia screening with high-definition white light colonoscopy, comparing a strategy of sampling visible lesions alone to a conventional strategy of sampling both visible lesions as well as normal-appearing mucosa using non-targeted biopsies. The primary outcome is the neoplasia detection rate. The required sample size to demonstrate non-inferiority is 1952 persons.
Use of Autologous, Adult Adipose-Derived Stem/Stromal Cells in Inflammatory Bowel Disease
Inflammatory Bowel DiseasesInflammatory Bowel Disease (IBD) is a group of inflammatory conditions of the small bowel and colon. Main types include Ulcerative Colitis and Crohn's Disease. Symptoms are often difficult to distinguish except for location and nature of changes. IBD complex arises with interaction of environmental, genetic factors, immunological responses, and chronic and recurring inflammation. Many factor appear as contributory, but no single set of issues appear to explain the process. Microbiota, intestinal wall granulation or breach, dietary, genetic predisposition all appear to factors. Treatment is often reactive or suppressive medications, neither of which appears to reverse the disease processes. This study explores the value of a complex group of adipose-derived stem/stromal cells (AD-cSVF) in the disease process.
