Active clinical trials for "Crohn Disease"

The purpose of the study is to investigate phospholipid ligands and their receptors in inflammatory bowel diseases and colon cancer. Several new species of lipids have been recently discovered which are able to transmit information to cancer cells in the large intestine. The lipids and their responsive receptors build an axis that is thought to influence the development of inflammation and cancer.

Prognostic factors in Inflammatory Bowel Diseases (IBD) are currently mainly based on clinical factors (disease extension, perianal involvement, need for surgery, use of immunomodulators…). All of immunological markers (or serological) of IBD have a diagnostic role in indeterminate colitis (ulcerative colitis vs crohn's disease) but they never have been considered as predictors of IBD course in adults. Among the most used, anti-neutrophil cytoplasm antibodies (ANCA) and Anti-Saccaromyces cerevisiae antibodies (ASCA) allow the distinction between ulcerative colitis (ANCA+/ASCA-) and Crohn's disease (ANCA-/ASCA+), and their combined use has a sensitivity and a specificity of about 85%. However, 10 other antibodies have been identified and recently evaluated individually in IBD and especially in pediatric Crohn's disease: anti-ompC, anti-I2, anti-flagellins, anti-glycan (anti-laminaribioside carbohydrate antibodies (ALCA), anti-mannobioside carbohydrate antibodies (AMCA), anti-chitobioside carbohydrate antibody (ACCA), anti-chitin and anti-laminarin), anti-goblet cells and anti-C.albicans specific mannans antibodies. These complementary tests improve the reliability of the diagnosis. In a previous cross-sectional work on a cohort of 195 IBD patients, the investigator showed a prognostic role of some of anti-glycan Abs and especially a correlation with a pejorative form of the disease both in Crohn's disease than in Ulcerative Colitis (UC) and a prediction of corticodependency in IBD.

The primary objective of this study is to retrospectively compare the perioperative and short-term (discharge through 30 days) outcomes of intracorporeal and extracorporeal anastomosis in minimally invasive right colectomies for benign and malignant disease. The secondary objective of this study is to retrospectively compare the rates of incisional hernia (up to 6 month post procedure) between intracorporeal and extracorporeal arms.

The primary objective is to obtain stool samples from subjects diagnosed with , and displaying signs and/or symptoms of IBD and/or IBS will be evaluated in this study. Eligible subjects require a diagnostic colonoscopy with possible biopsy and clinical evaluation.

The purpose of this study is to establish the incidence of sub-optimal response to anti-TNF therapy in UC and CD participants.

Nearly three-quarters of patients with Crohn's disease have small bowel involvement and 80% of them will have complications that will require a surgical procedure, usually an ileocolonic resection with ileocolonic anastomosis. The rate of recurrence at the anastomosis site and in the ileum after surgery, whether symptomatic or not, is high, at least 60% in one year and 80% within three years. The gold standard for monitoring being ileocolonoscopy, endoscopic surveillance is recommended in these patients, once between 6 to 12 months after surgery and then every 2 years. The MRI enterography is a validated technique for the assessment of small bowel Crohn's disease. The enterography MRI is a validated technique for the assessment of small bowel Crohn's disease. The MRI enteroclysis was evaluated in two studies compared to endoscopy, with excellent performance in terms of recurrence detection sensitivity and suggested as an alternative to it to avoid an invasive procedure repeated in these patients. The MRI enterography (without enteroclysis) does not provide as good distension of the bowel loops as MRI enteroclysis because it relies on the principle of oral ingestion prior to the examination of large amounts of liquid. However, it is much better tolerated by the patient, does not involve radiation that exists with enteroclysis, is much simpler to use and requires no special equipment to magnetic fields.

A study to describe the one-year persistence in participants treated by Flixabi (infliximab) or Imraldi (Adalimumab) as prescribed by the physician for each of the 5 following indications: Rheumatoid Arthritis (RA), Ankylosing Spondylitis (AS), Psoriatic Arthritis (PsA), Crohn's Disease (CD) [adults and children] and Ulcerative Colitis (UC) [adults for both treatments and children only for Flixabi].

The incidence of Crohn's disease (CD) increased the last few years, especially in children, with 20% percent of CD patients diagnosed during childhood. The CD is a chronic disease without curative treatment, medical or surgical, and evolution is longer in children, avoid iterative digestive resections and their consequences in these patients is a major issue. The beginning of the disease at pediatric age is considered to be a poor prognostic factor and is considered to be more aggressive than that of adults: more extensive, more active and requiring more immunosuppressive treatments, with a more frequent dependence on corticosteroids and a shorter delay between the beginning of symptoms and the first surgery. After 5 years of evolution, 13 to 50% of patients with early pediatric MC have undergone intestinal resection. The Paris' classification defined 3 phenotypes or behaviors in pediatric Crohn's disease. Penetrating phenotype (B3) is a heterogeneous group defined by the presence of intra-abdominal perforation, fistulas or abscesses. The B3 phenotype is a risk factor for pejorative evolution in CD with a risk increased of surgical resection. In the pediatric population, the natural history of patients with penetrating CD is unknown. Most studies focus on CD beginning at pediatric age but with penetrating complications occurring in adulthood or pediatric penetrating CD but with relatively short follow-up. The risk of recurrence of the penetrating disease after a first complication in childhood is unknown, the factors influencing this risk also. And, there is no consensus either concerning optimal B3 management in children, and the practices are variable from specialist to specialist. After describing the pediatric population with penetrating CD, the aim of this study was to know the incidence of bowel resection for B3 episode. The secondary aims were to describe the immediate management and long-term evolution of these patients and to identify risk factors for adverse evolution.

The purpose of this program is to provide early access to ustekinumab where it is commercially unavailable for the treatment of participants with moderately to severely active Crohn's disease who have failed treatment with conventional Crohn's disease therapy (example, immunomodulators or corticosteroids) and Tumor Necrosis Factor alpha (TNF alpha) antagonist therapy (e.g., infliximab, adalimumab, certolizumab pegol, or their biosimilars), or who are intolerant to, or have a contraindication to these treatments. During the course of this early access program (EAP), through the reporting of serious adverse events (SAEs) and non-serious adverse drug reactions (ADRs) by participating physicians, information on the safety and tolerability of ustekinumab will be captured.

This case control study aims to determine whether spontaneous coronary artery dissection (SCAD) is associated with autoimmune diseases and to update the incidence of SCAD in a population-based cohort.
