NCT04082559
Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases (IBD) currently affecting over 5 million patients globally, mostly young adults. These conditions are often debilitating, disabling and may markedly affect patient's quality of life. Despite important advances in research, the pathogenesis of IBD remains obscure, the incidence-rising, the condition - incurable, and drugs have a modest effect. The common denominator may be environmental factors, specifically diet and the microbiome, which remain a fundamental unmet need in IBD care as high quality randomized trials and mechanistic research are limited. Up to a quarter of patients with UC may undergo complete large bowel resection due to disease complications. In order to preserve bowel continuity, this surgery includes a restorative part with creation of a reservoir ("pouch") from normal small bowel instead of the resected rectum. The majority of these patients develop small intestinal inflammation in the previously normal small bowel creating the pouch ("pouchitis"). Based on our results from previous studies, we hypothesized that personalized antibiotics and dietary interventions will modify microbial composition and result in significantly improved outcomes, specifically resolution of inflammation and prolonged remission rates in patients with a pouch. Aims: 1. Compare the effect of two antibiotic treatments on clinical, inflammatory and microbiological outcomes of patients with pouch inflammation. 2. Evaluate the effect of combined microbiome-targeted antibiotic and dietary intervention as treatment and prevention strategy in patients after pouch surgery. 3. Evaluate the effect of a microbiome-targeted dietary intervention as prevention strategy in patients after pouch surgery. 4. Identify predictors for response to specific antibiotic and dietary interventions.

The primary objective of this study is to evaluate long-term effectiveness of adalimumab in pediatric participants starting a treatment for Crohn's disease in real life conditions, namely to describe the time to loss of clinical benefit in a time to event approach. Main secondary objectives are to describe growth and pubertal development and to describe long-term safety. The participants will be followed-up up to 10 years.
NCT04349449
The purpose of this study is to describe physician-reported clinical effectiveness outcomes, as determined by Harvey-Bradshaw Index (HBI) assessment, in biologic-naive participants with CD over 12 months following treatment initiation with vedolizumab.
NCT03725124
This study explores the lived experiences of family planning for women with inflammatory bowel disease (IBD) and their partners during the reproductive stages of pre-conception, pregnancy and the postnatal period through qualitative interviews. Insights from existing literature alongside findings from interviews and focus groups with patients and healthcare providers to develop an intervention to address the issues and support needs as identified by study participants.
NCT03565432
Inflammatory bowel diseases (IBD) is a chronic inflammatory condition of the gastrointestinal tract that significantly affects quality of life of patients. Several studies have reported that the loss of work productivity is significantly higher than that of the general population due to disease-related symptoms and various factors in patients with inflammatory bowel disease in Western countries, but there is few data in Korea. Therefore, this study is to assess the effect of disease on sick leave, work disability and health related quality of life in Korean patients with inflammatory bowel disease by using validated questionnaires.

This study is designed to explore the expression of cell-surface markers in the following seven disease areas: (a) systemic lupus erythematosus, (b) Sjogren's syndrome, (c) multiple sclerosis, (d) systemic sclerosis, (e) Crohn's disease, (f) ulcerative colitis and (g) inflammatory myositis.
NCT01876264
The trial will investigate if removing an additional length of small bowel will result in lower risk of recurrence at the surgical join (anastomosis), thereby decreasing the need for further surgery in the future.
NCT04297566
This study offers a questionnaire to patients with Crohn's disease in order to assess their physical activity and / or sport as well as their eating habits in order to assess the impact of these lifestyle habits on activity and the symptoms of the disease.
NCT03689257
This is a prospective, observational, multicenter, population-based incidence cohort study which will enroll cases of inflammatory bowel disease IBD (Crohn´s disease CD, ulcerative colitis UC, or indeterminate colitis) diagnosed in adults over 18 months in Spain. In addition, each incident case that gave his/her informed consent, will be followed up for 12 months to determine changes in phenotype or disease location, the need for immunosuppressive and biologic treatments, and the need for hospital admissions and surgery during the first year after diagnosis. Also, samples of of blood, urine and stool will be collected during the first year after diagnosis
NCT01155362
The primary objective of the study is to estimate the treatment effect of PDA001 (evaluating 3 different PDA001 dosings) versus placebo in subjects with moderate-to-severe Crohn's Disease. The secondary objective of the study is to assess the safety and tolerability of PDA001 versus placebo in the above-mentioned patient population.
NCT03939117
The aim of this study is to evaluate if an intraoperative protocol for Ultrasound scan (USS) is feasible and safe in patients undergoing elective surgery for ileocolic CD. The results of this study could guide the development of a larger randomised trial.
NCT00855907
Fatty liver is known to be one of the most frequent liver pathologies in IBD patients (35-40%). Despite this fact, there are only few publications that evaluated the prevalence of fatty liver in IBD patients. Moreover, the pathogenesis of this phenomenon in IBD has not been widely investigated. The paradox of lean patients and fatty liver can be explained by high use of steroids, by rapid weight loss, and by the abundance of TNFα cytokine in IBD patients that causes insulin resistance. The aim of the study: To evaluate the frequency of fatty liver in a cohort of IBD patients and to learn its risk factors. Methods: One hundred consecutive IBD patients treated at the Tel Aviv Sourasky Medical Center will be recruited. Patients will fill up a questionnaire regarding their disease, demographic data, other co-morbidities and medications and risk factors for metabolic syndrome. Each patient will undergo blood examinations in order to assess inflammation, and metabolic status. Fatty liver will be assessed by liver ultra-sonography.
NCT00353639
This study will evaluate and compare the genes of the telomere repair complex in healthy control subjects, patients with blood diseases, and patients with inflammatory bowel disease to identify what, if any, changes are associated specifically with inflammatory bowel disease. Patients between 2 and 80 years of age with ulcerative colitis or regional enteritis may be eligible for this study. Participants are recruited from the practice of Dr. Stuart Danovitch, Washington, D.C. Researchers have established that minor differences in a specific set of genes called the telomere repair complex are related to immune-mediated diseases of the bone marrow. NIH researchers are now interested in whether inflammatory bowel disease and other autoimmune diseases show a similar pattern of genetic differences. Participants provide a cell sample for evaluation of the telomere repair complex. The sample is collected via buccal swab, a gentle scraping of the inside of the cheek, and stored for use in research.
NCT03847753
Mental disorders have been shown to be associated with a number of general medical conditions (also referred to as somatic or physical conditions). The investigators aim to undertake a comprehensive study of comorbidity among those with treated mental disorders, by using high-quality Danish registers to provide age- and sex-specific pairwise estimates between the ten groups of mental disorders and nine groups of general medical conditions. The investigators will examine the association between all 90 possible pairs of prior mental disorders and later GMC categories using the Danish national registers. Depending on whether individuals are diagnosed with a specific mental disorder, the investigators will estimate the risk of receiving a later diagnosis within a specific GMC category, between the start of follow-up (January 1, 2000) or at the earliest age at which a person might develop the mental disorder, whichever comes later. Follow-up will be terminated at onset of the GMC, death, emigration from Denmark, or December 31, 2016, whichever came first. Additionally for dyslipidemia, follow-up will be ended if a diagnosis of ischemic heart disease was received. A "wash-out" period will be employed in the five years before follow-up started (1995-1999), to identify and exclude prevalent cases from the analysis. Individuals with the GMC of interest before the observation period will be considered prevalent cases and excluded from the analyses (i.e. prevalent cases were "washed-out"). When estimating the risk of a specific GMC, the investigators will consider all individuals to be exposed or unexposed to the each mental disorder depending on whether a diagnosis is received before the end of follow-up. Persons will be considered unexposed to a mental disorder until the date of the first diagnosis, and exposed thereafter.
NCT03998449
Assessment of the immunogenicity and safety of immunization against cholera in children with inflammatory bowel disease.
NCT02322307
HealthPROMISE is a mobile application (app) for patients that allows regular tracking of symptoms by patients and communicates them to physicians. The purpose of this randomized controlled trial is to determine the impact of the HealthPROMISE application on improving patient outcomes. The trial will look at how much patients use the application, whether physicians change treatment in response to new information from patients, and how the patients quality of life change over the span of the study. The investigators hypothesize that HealthPROMISE will enhance physician-patient communication and improve clinical outcomes.
NCT02825914
Casein glycomacropeptide (CGMP) has anti-inflammatory properties in experimental rodent colitis and using human in vitro inflammation models. Its use as a food ingredient has proven safe and with no influence on dietary intake. In a pilot study the investigators found, that orally administered CGMP seems to have a beneficial effect comparable to that of mesalazine in active distal ulcerative colitis. The investigators wish to evaluate the effects in a larger group of patients with active ulcerative colitis by studying the clinical effects and assessing the anti-inflammatory and microbiome modulating properties.
NCT03262727
The purpose of this study is to investigate the effect of BMS-986165 in combination with an oral contraceptive in healthy female patients.
NCT03264690
This study will be conducted to observe the difference in microbiome composition between healthy participants and inflammatory bowel disease (IBD) participants with no anti-tumor necrosis factor (anti-TNF) treatment.
NCT04296500
This study aimed to identify inflammatory bowel disease (IBD) patterns based on presenting symptoms and to suggest algorithms for determining pattern and herbal prescriptions for corresponding patterns. The investigators collected symptom data of 67 IBD patients who achieved and maintained clinical remissions after they had taken herbal medicine prescriptions. Prescriptions were categorised into 5 patterns, which were named after main features and symptoms of included patients. Associations between presenting symptoms and patterns were visualised using a term frequency inverse document frequency (TF-IDF) method. Determining IBD patterns from symptoms of patients was analysed and charted by decision tree modeling.
