NCT06244849
Crohn's disease (CD) belongs to chronic inflammatory bowel diseases (IBD) affecting over 2 million individuals in the North America and 3.2 million in Europe with an increasing incidence rate in newly industrialized countries experiencing a westernization of lifestyle (1). This highly disabling disease affects patients' life in several ways with severe complications requiring surgery for half of them and is responsible for considerable economic burdens (2,3). Decades of research displayed that CD pathogenesis is determined by inappropriate immune responses towards luminal microbiota in genetically susceptible hosts. Genome-wide association studies (GWAS) have identified autophagy as one of the main pathways associated with susceptibility to CD (4-6). Autophagy is a dynamic process of the lysosomal catabolism, called autophagy flux, which is crucial to degrade and recycle obsolete and deleterious cytosolic components of the cell (7). Autophagy is also the main cell-autonomous process to fight intracellular microorganisms by degrading them, and by contributing to antimicrobial host immune responses. However, the functional consequences of polymorphisms affecting autophagy-associated genes on the dynamic process of autophagy and its real impact on CD pathogenesis remain largely unknown. In addition, CD is associated with a gut microbiota dysbiosis, as exemplified by the higher prevalence of AIEC (a bacterium eliminated by autophagy) in ileal mucosa of CD patients (8-10). Hence, autophagy defect, linked to autophagy SNPs, could contribute to CD-related dysbiosis and to CD activity and severity. Beyond, CD-associated abnormalities of the autophagy flux may affect the composition of the autophagic cargoes, as well as the one of other vesicular pathway, such as exosomes, known to influence autophagy. These impairments could affect at longer term both cell activities and immune responses, especially in antigen presenting cells, which drive host immune responses. The TOPIC project concerns translational research, in which we plan to generate a prospective cohort of CD patients giving up the unique opportunity to collect clinical data, to analyse simultaneously the autophagy flux, genetic variants of interest (from blood samples) and intestinal microbiota (from intestinal samples) and allowing to perform more fundamental studies. The results of the fundamental part will allow a better understanding of the pathophysiology of CD, and ultimately better management of these patients.
NCT06421116
This project aims to develop and validate a model of human organoids derived from patients with Spondyloarthritis, focusing on synovial and intestinal tissues as targets of the gut-joint axis. The tissue marker profile of patient-derived organoids studied by gene expression, immunohistochemistry, and cytokine production profile will be compared with that of controls in order to test for the presence of specific biomarkers.
NCT04912999
The inflammatory bowel diseases (IBDs), ulcerative colitis (UC) and Crohn's disease (CD), are characterized by lifelong relapsing-remitting gastrointestinal inflammation, with symptoms of abdominal pain, diarrhea, and rectal bleeding during active disease. Medical therapy reduces intestinal inflammation and ameliorates symptoms. Clinical remission is defined when symptoms are resolved. In these periods, patients are able to perform daily activities more freely and lead a normal lifestyle. Biochemical remission (normalization of CRP and fecal Calprotectin) and endoscopic remission (no visual signs of inflammation of the mucosa in endoscopy) are the goals of IBD treatment. Unfortunately, 30-40% of patients will relapse during 6 months from achieving remission. Risk factors for disease exacerbation are still unknown, and no guidelines exist as to the prevention of relapse and maintenance of remission in IBD patients. In addition to the above, sleep disturbances and disturbances in the circadian rhythm can be a potential cause of flare-up. Sleep disorders cause changes in immune function, which later affect the course of the disease in IBD. This back affects the sleep pattern, so that a cycle is created, which may perpetuate the inflammation. The interactions between sleep and inflammation are complex. An effective immune system affects sleep, and sleep disorders affect the functioning of the immune system. Furthermore, changes in the biological clock and sleep deprivation have been directly shown to worsen ulcerative colitis in laboratory animals. In people with sleep disorders, high levels of inflammation were found. However, it is difficult to dissect the cause and effect for these associations, given their complex interactions. Therefore we are planning to conduct a prospective study to assess variety of factors that might be associated with the activity of IBD.
NCT06407674
At enrollment, after informed consent form will be discussed and signed, subjects will undergo complete disease assessment. In this study, 150 adult subjects with IBD will be enrolled at the Gastroenterology Department of the San Raffaele Hospital (50 patients with Crohn's disease, 50 with Ulcerative colitis not undergoing proctocolectomy, and 50 with Ulcerative colitis undergoing proctocolectomy with ileal pouch-anal anastomosis). All the patients will perform routine investigations with Ileocolonoscopy (IC), according to the current standard of care indications and ECCO guidelines, and they will be assessed by both Intestinal Ultrasound (IUS) and Trans-perineal ultrasound (TPUS). Blood and stool samples will be obtained for fecal calprotectin (FC) and C-reactive protein (CRP) measurements, respectively, as normal clinical practice. All the procedures of this study are performed routinely in clinical practice. All the procedures are performed in a single day-visit for the patient.
NCT04898530
The purpose of the study is to understand the diet patterns, preferences, and impact of diet on daily living in our patients with IBD in Central Texas.
NCT02263703
Genital HPV is the necessary cause for cervical cancer, as well as a major contributing cause of several other cancers and conditions. There are now effective vaccines against the main oncogenic HPV types, HPV16 and 18. Most research and discussion has focused on targeting the vaccine to young women and older adolescents. Based on this, a national free HPV vaccination program for adolescent girls commenced in 2007, in Australia. However, at the time of commencement, there had been no research on the use of this vaccine in immunosuppressed. Therefore, information on the immunogenicity, safety and duration of efficacy of HPV vaccine when administered to immunosuppressed children is needed. This trial looked at a 3 dose schedule of quadrivalent HPV vaccine in a range of immunosuppressed children, with the endpoint being immunogenicity, followed for 5 years for duration of immunity.
NCT06392061
The study is a single-center, randomized, single-blinded, controlled trial conducted at ZHUMC's endoscopy unit. It aims to assess the short-term effects of probiotic administration on disease course, quality of life, and nutritional status among patients diagnosed with inflammatory bowel disease (IBD), specifically ulcerative colitis (UC) and Crohn's disease (CD). Patients with UC and CD will be recruited from the endoscopy unit's outpatients and divided into two groups: a control group and an intervention probiotic group. The intervention probiotic group will receive the probiotic intervention for 2 months. During the study period, two visits will be scheduled for all patients. At each visit, medical and nutrition surveys will be filled out, and body composition measurements will be conducted. These assessments will help evaluate the impact of probiotic administration on the participants' disease progression, their quality of life, and their nutritional status. Overall, the study aims to provide insights into the potential benefits of probiotic supplementation in managing IBD and improving the well-being of patients with these conditions.
NCT02647866
The purpose of this study is to determine the safety and tolerability of administration of multiple ascending doses of KHK4083 and to select the highest dose tolerated by subjects with moderately active Ulcerative Colitis (UC) followed by a Long-term Extension Therapy (LTE) phase for eligible subjects with a clinical response.
NCT03558048
This study will measure Prostate Specific Antigen (PSA) values in men with Inflammatory Bowel Disease (IBD) before, during, and following a flare. In addition, the effect of any PSA increase will be analyzed and correlated to the location of disease (rectal vs. other). Study findings may help men with IBD by identifying pitfalls in prostate cancer screening for this population and help to stratify and understand the effect IBD has on the prostatic milieu. By optimizing how men with IBD are screened for prostate cancer, future unnecessary healthcare encounters and expenditures may be reduced for this patient group.
NCT01790061
The gut microbiota is considered to constitute a "microbial organ" which has pivotal roles in the intestinal diseases and body's metabolism. Evidence from animal and human studies strongly supports the link between intestinal bacteria and inflammatory bowel diseases (IBD). Dozens of studies reported its efficacy in treatment of severe Clostridium difficile colitis. Preliminary studies using FMT for Ulcerative Colitis (UC), Crohn's diseases, irritable bowel syndrome (IBS) and constipation have also met with some success. This is an initial step into investigating the potential efficacy of standardized fecal bacteriotherapy through mid-gut (at least below duodenal papilla) for UC, the investigators propose to determine the efficiency and safety of FMT in a series of 500 patients with moderate to severe UC (Montreal classification).
NCT05221281
Background: Transition in care is defined as the "purposeful and planned movement of adolescents and young adults with a chronic medical condition from pediatric to adult-oriented healthcare systems/care providers." Currently, there is no Level 1 evidence of an intervention to improve the care of transitioning adolescents and young adults (AYAs) with inflammatory bowel disease (IBD). The development of a transition program using a biopsychosocial approach will improve the standards for healthcare delivery to transitioning IBD patients. This is a protocol for a structured randomized controlled trial (RCT) to assess the efficacy and impact of a multimodal intervention focused on improving patient function, transition readiness and outcomes among AYA patients with IBD being cared for at pediatric centers in Canada. Methods: This multi-center RCT is a type 1 hybrid effectiveness-implementation trial to evaluate effectiveness of the intervention and how it can be implemented more widely after the trial. We will include patients aged 16.0 to 17.5 years. The intervention program consists of 4 core components: 1) individualized assessment, 2) transition navigator, 3) virtual patient skills-building with a focus on building resilience, self-management and self-efficacy, and 4) a virtual structured education program. The control group will undergo standard-of-care defined by each participating center. The primary outcome will be the IBD Disability Index, a validated measure to assess patient functioning. Secondary outcomes include transition readiness, anxiety and depression scales, and health service utilization rates. Additionally, we will identify the effectiveness of an evidence-based implementation approach and related barriers and facilitators for the intervention program. Discussion: The type 1 hybrid effectiveness-implementation design will allow us to develop a feasible, sustainable, and acceptable final intervention model. The intervention will consist of modules that can be accessed in an online, virtual platform. The implementation will not depend on individual hospital resources, allowing centralization of interventions and funding. The authors anticipate that the main study limitation will relate to study subjects not completely adhering to every component of the intervention, which will be evaluated and addressed using the implementation science approach.
NCT04885920
Inflammatory bowel disease consists of either ulcerative colitis (UC) or Crohn's disease (CD). The main aim of this study is to describe real-world treatment patterns in adults with moderate to severe ulcerative colitis or Crohn's disease when treated with vedolizumab. This will include the administration choices which can either be an infusion through a vein (intravenous or IV), or an injection just under the skin (subcutaneous injection, or SC). Treatment will be determined by the study doctor according to routine clinical practice.
NCT06362174
The research group have previously evaluated the benefit of serial consecutive capsule endoscopy as monitoring tool for Crohn's disease in remission, demonstrating its superior accuracy for disclosing inflammation and for prediction of flares in comparison to other diagnostic modalities such as magnetic resonance enterography and inflammatory biomarkers. Subsequently, deep learning algorithms had developed to provide excellent accuracy for identification and grading of ulcers and intestinal strictures on capsule endoscopy still images. The investigators will advance this knowledge using a parallel two-parts approach.
NCT06353633
In this study, children and adolescents with active Crohn's disease are placed in two intervention groups, the first group receives only an exclusion diet and the second group receives an exclusion diet plus formula.
NCT05291039
This study aims to assess trough, TREM-1 levels and efficacy of IFX and ADA in IBD patients.
NCT05657197
In patients with inflammatory bowel diseases (IBD), characterized by relapsing intestinal inflammation, chronic fatigue is a burdensome and highly prevalent symptom. The aetiology is thought to be multifactorial, including complex interactions of psychological and physical factors such as immunological profiles and gut microbiota. Unfortunately, specific treatment strategies are currently lacking. Since fatigued patients have an impaired physical fitness and are less physically active than patients without fatigue, it is hypothesised that physical exercise might be an effective complementary treatment for patients with IBD suffering from fatigue. During a previous pilot cohort study, significant improvements in fatigue complaints and quality of life were observed following a personalised and intensive exercise program. In this study, a multicenter randomized controlled trial will be performed to further investigate this assumed beneficial effect of intensive physical exercise.
NCT04567628
The purpose of this study is to determine if a relationship exists between Week 6 vedolizumab therapeutic drug monitoring (TDM) and Week 30 Faecal calprotectin (FCP).
NCT03449069
The purpose of this study is to determine the safety of using an autologous mesenchymal stromal cell (MSC) coated fistula plug in people with fistulizing Crohn's disease. Autologous means these cells to coat the plug come from the patient.
NCT05394272
Paediatric and adolescent patients with chronic pain associated with their medical condition will be invited to participate in this study. Most patients for this study will be recruited from gastroenterology and hepatology clinics at KCH. Therefore the rationale for the study is primarily with consideration of each of these medical conditions all with the common symptom of chronic pain. Inflammatory bowel disease disorders(IBD), such as Crohn's Disease and Ulcerative Colitis, disorders of gut-brain interaction (DGBI) all experience chronic pain. however children with DGBI do not have an underlying specific lesion causing the pain. The chronic pain is the disease. In addition to this Chronic pancreatitis in children and adolescents can cause severe pain. All of these groups of patients suffer with chronic pain and this can result in failure to thrive and have a negative impact on quality of life. There is a need for further development of a non - pharmacological approach to support these patients with their symptoms of pain and in turn improve quality of life. This study is designed to evaluate the benefits of a complementary natural therapy for paediatric and adolescent patients registered at King's College Hospital, with a diagnosis of a disease or disorder with associated symptoms of chronic pain. The age group is 5-18 years old. The therapy to be evaluated is an energy therapy (Pranic Healing). This therapy is non -invasive, non- touch, non- pharmacological and natural. The study will assess the benefits these patients experience with their symptoms of pain after 8 weeks of weekly energy therapy sessions each session is 30 minutes and 3 visits each 4 weeks apart. Qualitative and Quantitative data will be collected and evaluated.
NCT02517684
The purpose of this study is to determine whether a top-down treatment approach, prescribing infliximab (IFX) and azathioprine (AZA) at diagnose, yields better outcome in comparison to the usual step-up treatment approach, starting with prednison and AZA or exclusive enteral nutrition (EEN) and AZA, in moderate-to-severe pediatric Crohn's disease (CD) patients.
