Active clinical trials for "Crohn Disease"

Patients with chronic inflammatory diseases (CID) followed in gastroenterology, dermatology and rheumatology have physiopathological, epidemiological and therapeutic focal points. The pathologies concerned are inflammatory bowel diseases (IBD - Crohn's disease [MC] and ulcerative colitis [RCH]), chronic inflammatory skin diseases (psoriasis or Verneuil's disease) and chronic inflammatory rheumatic diseases (rheumatoid arthritis [RA] and spondyloarthritis [SpA] including psoriatic arthritis [PsA]). Presenting one of these diseases is associated with a higher risk of having a second inflammatory pathology, whether the latter is ophthalmological, dermatological, rheumatological or gastroenterological. An association of extra-articular manifestations is observed in 10 to 30% of patients with SpA, and an association of extra-intestinal manifestations is observed in approximately 30% of patients with IBD. No common database for chronic systemic inflammatory diseases currently exists in France.

Natural Language Processing and machine learning are examples of artificial intelligence tools. This study will check if these tools correctly identify people with Crohn's disease with complex perianal fistulas from their medical records.

To develop and train a convolutional neural network to detect and characterize disease severity of inflammatory bowel disease during endoscopy

The cause of CD could be different according to age at onset of CD symptoms. Indeed we know that some very young patients at CD diagnosis have particular genetic variants as abnormalities of the IL10R that are regarded as quite monogenic disease. In the other way, the microbiota also undergoes substantial changes at the extremes of life, in infants and older people and the ramifications of which are very few being explored. The comparison of microbiota by principal component analysis and genetic profile of patients with CD beginning at the extremes of life could help us to better known physiopathology of CD according to age and provide arguments that CD beginning at the extremes of life could be different diseases. The aim of the study is to ascertain through population-based study the hypothesis that gut microbiota is different between paediatric-onset and elderly-onset CD patients in relation with genetic and environmental mechanisms. The results will provide a better knowledge of the etiopathogenic ways in CD and propose a personalized therapeutic care based on age at CD onset (i.e. according to the gut bacteria involved).

The aim of this study is to identify new genes in Chinese patients that help investigators to understand the biological pathway and functions in a population in whom the incidence of Inflammatory Bowel Disease (IBD) is increasing. And to explore the genetic variations in Chinese patients with IBD.

Inflammatory bowel disease (IBD) is a chronic inflammatory condition for gastrointestinal tract. There have been numerous studies to reveal dysbiosis of fecal/mucosal microbiome composition in IBD patients but actual trend of dysbiosis is strikingly different among patient's ethnicity. In this background, the investigators have composed a prospective cohort of Korean IBD patients in a large academic referral IBD center. Using an integrated multi-omics bioinformatic analysis, the investigators aim to explore gut microbial signatures along with distinct clinical/genetic features, and their potential interplay in patients with IBD.

The precise and noninvasive evaluation of disease activity among patients with Crohn's disease is not easy, especially for children. It deals with clinical, biological, histological and radiological parameters. Bowel sounds (BS) when evaluated by a stethoscope are modified by several factors including surgery, infection, drugs or intestinal inflammation. These factors can interact on intestinal motricity. There is a direct relationship between gastrointestinal motility and characteristics of BW. The study of BS using a stethoscope is a simple method, although operator dependent and subjective,with a wide inter and intraindividual variability. Some studies among adults showed interest in the spectral analysis of BS to assess gastrointestinal motility. This more precise and reproducible method is not operator dependent. To date, no such study has evaluated the correlation between disease activity and the spectral pattern of BS. of this project is to assess the correlation between disease activity and the spectral pattern of BS in pediatric Crohn's disease.

Crohn's disease (CD) is a life-long chronic inflammatory bowel disease (IBD) that may affect any site of the gastrointestinal tract, most frequently the ileum and colon. It is characterized by transmural inflammation and it can lead to strictures, due to activation of reparation of inflamed tissues and consequent fibrosis, or penetrating lesions, such as fistulas, between two different intestinal tracts or between intestine and surrounding organs. Fistula occurrence can lead to formation of abdominal or pelvic abscesses. Such complications cause intestinal damage and usually require surgery, leading to disability, impairment of patients' quality of life, with significant impact on direct and indirect health-care costs

The SIMBA Capsule is a small, single-use, ingestible capsule that allows for the non-invasive sampling of small bowel contents using purely mechanical means. The study will compare the microbial and metabolomics analysis from the sample collected with the capsule series, to same-participant symptom questionnaires and stool microbial analysis.

This is a longitudinal, observational study that aims to identify the microbial and human molecular triggers of IBD flares via stool, saliva, and blood metatranscriptomes, whole blood proteome, and collected clinical metadata. This study is direct to participant and will not utilize clinical sites.
