COmparison of MicroBiota AccordIng to Age in Crohn's Disease (COMeBACk)
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...
Contrast Enhanced Ultrasound in Human Crohn's Disease-Lumason
The investigators plan to compare contrast-enhanced ultrasound to CT and MRI for the detection and quantification of intestinal inflammation in the the setting of pediatric small bowel Crohns disease
Contribution of a Non Medicamentous Approach by Hypnosis on Quality of Life in Crohn Disease
Evaluation of hypnosis therapy efficacy in addition to pharmacologic standard treatment of Croh disease during remission by the evaluation of quality of life;
Control Crohn Safe Trial
Crohn's disease (CD) is a chronic disease with a heterogeneous clinical presentation, relapse rate and treatment response. Insufficient control of mucosal inflammation results in irreversible bowel damage and complications and at present no markers are available to predict such a complicated disease course at diagnosis. Therefore, to prevent overtreatment of low risk patients, step-up treatment with subsequent introduction of corticosteroids, thiopurines maintenance and TNF-blockers if a previous category fails is standard care. Combination treatment with thiopurines and a TNF-blocker is more effective than monotherapy but associated...
COVID-19 Vaccination in Rheumatic Disease Patients
The research is being done to study the immune responses to COVID-19 vaccination in patients with rheumatic diseases.
Crohn's Disease Endoscopic REmission Definition in an Objective Way
The CDEIS (Crohn's disease endoscopic index of severity) and its derivative, SES-CD (single endoscopic score for Crohn's disease) were constructed to evaluate the endoscopic severity of Crohn's disease (CD). The current therapeutic goal in CD is endoscopic remission, which is thought to be predictive of a favourable evolution of the disease. However, up to now there is no measure of endoscopic remission, objectively constructed and validated, not even a consensus for its definition. An objective measure of endoscopic remission is necessary, notably for the evaluation of new treatments, a request of the regulatory agencies (FDA and ...
Data Collection Study of Patients With Non-Malignant Disorders Undergoing UCBT, BMT or PBSCT With RIC
This is a data collection study that will examine the general diagnostic and treatment data associated with the reduced-intensity chemotherapy-based regimen paired with simple alemtuzumab dosing strata designed to prevented graft failure and to aid in immune reconstitution following hematopoietic stem cell transplantation.
Decoding Personalized Nutritional, Microbiome and Host Patterns Impacting Clinical and Prognostic Features in Crohn's Disease
The study is 3 arms observational study with no intervention that aims to understand the link between Crohn's disease, microbiome and diet in children. 150 children newly diagnosed with Crohn's disease will participate in the study and their data will be used to create an algorithm about their microbiome, disease, diet, etc. 100 other children newly diagnosed will participate in the study and their data will be use to validate the algorithm. The investigators will be recruiting 50 healthy participants: 20 that are undergoing an endoscopy for abdominal pain and 30 that comes to the physician for different reasons. After...
Defining Predictors of RT Response to Vedolizumab in IBD
The overall goal of the study is to develop data that can convincingly guide clinicians on the use and efficacy of vedolizumab in patients with small bowel CD. There is an unmet need to identify response to vedolizumab in small bowel CD using objective endpoints. Current data suggest that MR enterography may meet this unmet need. There is an additional unmet need to develop predictive models incorporating both clinical and baseline radiological and endoscopic variables with higher discriminatory performance in identifying longer term clinical remission with vedolizumab. Finally, this proposal is strengthened by the exploratory...
Detection of Herpesvirus DNA (CMV, EBV, HHV-6 and HSV) in Colonic Tissue: Impact on Ulcerative Colitis Flare-up
Flare-up of ulcerative colitis (UC) is characterized by the inflammation of colon mucosa that requires the use of immunosuppressive therapies. In previous studies, the active role of cytomegalovirus (CMV) has been demonstrated, with a correlation between the cytomegalovirus DNA ((deoxyribonucleic acid) load in the inflamed tissue and the resistance to successive lines of immunosuppressive therapy (Roblin et al., Am J Gastroenterol 2011). The main aim of this monocentric prospective study is to evaluate the DNA viral load by qPCR (Polymerase Chain Reaction) of 3 herpesviruses (Epstein-Barr virus, herpes virus 6 and herpes simplex) ...
