Active clinical trials for "Crohn Disease"

The IBD South Limburg (IBDSL) project was initially designed as a prospective population based cohort study. Since 1991, all new IBD cases have been enrolled in the cohort and prospectively followed. As from 2011, the cohort is being scaled up into a population based biobank and focus expanded from epidemiology towards exploring underlying biologic mechanisms and identifying markers to predict disease course or therapy response. Every adult IBD patient, diagnosed in and permanently residing in South Limburg (The Netherlands), is eligible to participate. The population based nature was reached via a multi-faceted approach; incident cases were prospectively identified through the participating hospitals, and missed patients were retrospectively identified using the nationwide histopathology registry. In 2011, over 3500 patients were included, which represents 93% of the IBD population in South Limburg. The cohort includes baseline data, such as IBD phenotype, extent, location, behaviour, extra intestinal manifestations, medication, surgery, comorbidity and demographics. Data has prospectively been updated through chart review (clinical data), questionnaires (i.e. quality of life) and linkage to the authority database (vital state, residence). The biobank includes serum, plasma, DNA, faeces, biopsies and exhaled air. We welcome new collaborations. Applications for collaboration are first to be approved by our IBD-SL committee.

This study aims to investigate the role of non-genetic factors in the pathogenesis of inflammatory bowel disease.An exploratory study to investigate differences between the epigenome, microbiota and functional immunology in twins discordant for inflammatory bowel disease.

One hundred and fifty patients with Crohn's disease involving the terminal ileum or the colon, in clinical remission, with or without endoscopic activity will be included. Thrombin generation will be measured and correlated with the simplified endoscopic activity score. The patients will be evaluated for development of deep vein thrombosis after one-year of follow-up.

Goal is to prospectively determine if stool calprotectin and change in bowel wall thickness and hyperemia, as seen on small bowel ultrasound, at week 0, 14, and 54 can be used to predict response at week 54 to infliximab in pediatric patients with small bowel Crohn's Disease.

Inflammatory Bowel Diseases (IBD) is a heterogeneous group of diseases regarding clinical presentation, disease course and treatment response. Pathogenesis is complex and multifactorial, based on interactions between genetic and environmental factors, gut microbiota and the immune system, leading to intestinal inflammation. As the immune reaction itself causes the intestinal damage, differences in components of this immune mediated inflammatory reaction between IBD patients might explain the heterogeneity in response to different therapy strategies. Identifying immune components that are associated to disease activity and prognosis would enable a more personalized treatment.

Background theme Crohn's disease (CD) and ulcerative colitis (UC) are chronic diseases that alternate flares of active inflammation with periods of clinical remission. The working capacity of patients may be affected both by disease activity and by the aggressive treatment or surgical intervention required for the management of the disease and its complications. Work disability and impairment are especially important in patients with inflammatory bowel disease (IBD) because the disease affects young individuals who are generally employed and fully active. Although there are several indexes in the literature that assess the degree of work disability due to IBD, all have a high degree of subjectivity, so none can be used to request disability pensions. Experience of the research group on the subject Our group has developed a line of research on work disability associated with IBD. Initially the investigators have studied the parameters that condition the granting of disability pensions of Spanish courts. Subsequently, a population study of the prevalence of work disability in Spain has been carried out. Finally, the investigators develop and validated a disability index for CD (published in its extensive and reduced form) and for UC (currently under review). Hypothesis The IBD generates a work disability that can be measured objectively. Establishing the parameters related to disability is essential to promote equity in administrative and judicial decisions related to the granting of disability pensions to patients with IBD. Objective Development and validation of an objective index to measure the degree of disability in IBD. Material and methods: Study 1: A self-reported and objective questionnaire of disability will be developed based on the data of the population survey already carried out by our group. Patients from a previous study (n 293) will be included. The relationship of different objective variables and disability outcomes will be analyzed with a univariate and a subsequent multivariate analysis. Alternative work disability scores will be developed. Study 2: for the validation of the questionnaire a new online interview will be performed, patients from patients' assocations will be asked to participate. Data Collection: patients will answer a online survey administered with the SurveyMonkey © platform. Participant will answer questions about demographics, disease activity, treatment and complications and data regarding disability. Patients will also complete the SCDWDQ (Short Crohn's Disease Work Disability Questionnaire), Work Productivity and Activity Index (WPAI), IBDQ-9, the EuroQol and IBD-DI (IBD disability index). Statistical analysis: psychometric properties of the index will be evaluated: Convergent validity: the Spearman correlation will be used to correlate the objective disability score with IBD-DI and SCDWDQ. Discriminant validity: it will be measured by the t-test among patients with different degrees of disability (inactive-active, hospitalization-no hospitalization, surgery-no surgery).

This is a pro- and retrospective cohort study to evaluate the natural history and outcome of various treatment options of patients with fistula. At each clinical visit parameters describing activity of a fistula, potential underlying Crohn's disease, investigations as well as the current treatment will be entered into a database. Selected patients can also be contacted by phone in the form of a structured interview. Data will be analyzed to determine treatment outcomes, characterize the natural history as well as risk factors for complications of treatment and an unfavorable disease course. The same data will be obtained and analyzed retrospectively from patients who visited the clinic prior to January 2017.

The project will consist of a multicentre, prospective, observational study with a total duration of 24 months. Clinical, endoscopic and ultrasound data will be collected in a dedicated database (on IG-IBD Register), which will be used to identify potential clinical, endoscopic and ultrasound risk factors of re-operation. These data could be merged into a shared score, to stratify patients according to the risk of post-surgical re- operation and to define an optimal therapeutic management in the post- operative period. Approximately 220 adult patients, with a defined diagnosis of CD, who underwent a surgery for CD in the previous 6 months will be enrolled.

Inflammatory Bowel Diseases (IBDs) are a set of recurrent inflammatory conditions that include the colon and small intestine. The two principal conditions include Crohn's disease (CD) and ulcerative colitis (UC). The etiology of which is likely to stem from the interplay of gut microbial imbalances and host. In this study stool cultures, saliva and skin samples will be taken from all participants.

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding Crohn's disease.
