Active clinical trials for "Crohn Disease"

The purpose of this study is to explore the microflora characteristics of different ecological loci and multiple metabolic pathways in Crohn's disease patients with different disease course states.

The investigators intend to assess the role of several biomarkers in the prediction of relapse in IBD. Clinical, laboratory and endoscopic data will be gathered and a predictive score will be derived in order to assess the relapse risk at 1 year.

Abdominal pain is a common symptom in patients with Crohn disease (CD). Pain is multifactorial, may result from inflammation but persists in many patients during remission. The aim of our study is to determine the epidemiology of pain in CD patients and define the characteristics of pain : localisation, temporal and sensorial characteristics, neuropathic component, impact on quality of life and mood.

Patients with Crohn's disease generally have nutritional risks and malnutrition. The investigators will conduct a multicenter cross-sectional study to discover nutritional status and body composition of Chinese adult patients with CD.

The study has not yet been completed

A multi-center observational study based at referral centers and community hospitals within the US. Patients' blood will be collected at enrollment for testing with PredictSURE IBD™, which will occur at a later date. Patients will be prospectively followed up for 12 months with clinicians treating according to local standard of care, with a step-up or accelerated step-up regimen. Clinicians and patients will be blinded to the biomarker results.

The management of anal fistula in Crohn Disease is complex. In aim to obtain the healing of the anal fistula, different approaches can be proposed but the best strategy is not yet determined. The aim was to describe the therapeutic management of anal fistula in Crohn Disease.

the aim of this preliminary observational study is to compare external exposomes from 10 teeth issued through 10 subjects living in high incidence of crohn's disease area and 10 teeth issued through 10 subjects living in low incidence of crohn's disease area.

Crohn's disease is a chronic inflammatory transmural bowel disorder characterized by high rate of postoperative anastomotic complications and recurrences. Surgery itself can influence immunologic function and trigger inflammatory response, which may result in the flare of Crohn's disease soon after surgery (within one month), especially near the anastomosis. Early flare-up of Crohn's disease can negatively impact the outcomes of operation. However, due to the the complexity of perioperative period and dangerous of invasive examine, it is difficult to distinguish disease flare from postoperative complications. In this study, the investigators aim to development a diagnostic method of flare-up within one month after surgery, which can help us to detect and then treat disease flare in time.

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.
