Filter by:HLA-DQA1*05 variant carriers are at risk of developing antibodies against infliximab and adalimumab with reduced TNF antagonist persistence. The impact of proactive therapeutic drug monitoring (PTDM) on this association has been barely assessed. Therefor, we propose a cohort study including adult patients with Crohn's disease and ulcerative colitis treated with TNF antagonists under proactive therapeutic drug monitoring. Our hypothesis is that, proactive therapeutic drug monitoring could be an alternative to combination treatment with immunomodulators to increase TNF-antagonists' persistence in HLA-DQA1*05 carriers.
The inflammatory bowel diseases (IBD) are described as complex, recurrent inflammatory conditions which are manifested as Crohn's disease (CD) and ulcerative colitis (UC). The common symptoms of IBD include debilitating/severe diarrhea, abdominal pain, weight loss, and chronic fatigue; events that may culminate in life-threatening complications. The pathogenesis of IBD has been characterized as complex/multi-factorial that includes disruption of intestinal epithelial barrier with consequent translocation of commensal microbial products as the prime event that instigates severe immune responses and intestinal inflammation.
The effects of diet on inflammatory bowel disease is an under-studied area of research. The investigators are interested in further investigating the role that diet contributes to inflammatory bowel disease severity. The investigators will collect blood and stool samples from patients with inflammatory bowel disease (IBD) before and after diet changes. The stool samples will be analyzed using metabolomics and microbiome analysis to determine changes after the new diet has been implemented. The investigators will then compare changes in the patient's overall disease state by measuring markers of inflammation including C-reactive protein (CRP) and fecal calprotectin to determine how this diet affects the disease state.
The overall objective of this pilot intervention study is to determine the impact of grape powder (46g/day freeze dried whole grape powder provided by the California Table Grape Commission) on the gut microbiotacomposition in adult patients with the IBD subtype Crohn's disease (CD).
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract that includes ulcerative colitis (UC) and Crohn's disease (CD) . They mainly affect young populations, altering their quality of life and increasing morbidity, compared to the general population . The etiology and pathogenesis of IBD are still poorly understood. Inflammatory bowel disease (IBD) patients are at an increased risk of contracting and developing complications from hepatitis B virus (HBV) due to their weakened immune systems and frequent use of immunosuppressive medications. The traditional HBV vaccine regimen requires three doses over six months to achieve full immunity, which can be challenging for IBD patients who may have difficulty adhering to the schedule or may not respond well to the vaccine
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.
Methotrexate is one of the immunosuppressants used in chronic inflammatory bowel disease (IBD). It is indicated as monotherapy for induction and maintenance treatment of Crohn's disease (CD), or in combination with anti-tumor necrosis factor (TNF) agents for prevention of immunization. The main objective is to assess the persistence rate of methotrexate treatment in patients followed for chronic inflammatory bowel disease (IBD).
1. To compare adding dietary intervention based on MD to dietary intervention based on IBD-AID on induction of disease remission of IBD patients receiving pharmacotherapy. 2. To compare patients' adherence to dietary intervention based on MD to dietary intervention based on IBD-AID, and the impact of adherence on induction of remission among patients with IBD receiving pharmacotherapy.
Frequency of Inflammatory Bowel Diseases in children (IBD)-Crohn's disease (CD), Ulcerative colitis (UC) is constantly increasing. Pediatric-onset IBD represent a different nosological entity (from adult IBD) because of their major inflammatory activity, their significant anatomical extent and their stenotic and/or fistulizing character sometimes from diagnosis. Intestinal lesions are due to dysregulation of the intestinal immune system but the cause is unknown. The investigators hypothesize that extranuclear DNA participates in the amplification of the inflammatory response at the intestinal and blood levels during pediatric IBD through the cGAS-STING pathway. The investigators will analyse blood and fecal samples, and colonic biopsies issued from ill children and control participants on age of 6 to 17 years. The investigators think that this study will provide a better understanding of the mechanisms involved in pediatric IBD, assess the place of the cGAS-STING pathway, identify potential biomarkers of pediatric IBD and new potential therapeutic targets based in particular on the inhibition of the cGAS-STING pathway.
PSC is a liver disease that has no medical cure. Patients with PSC are at a greatly increased risk of cancer and infection. Additionally, many patients require a liver transplant. Progress towards a cure has been severely limited by an incomplete understanding of why patients develop PSC. The investigators aim to close this gap by conducting a pilot human study in patients with PSC, using statin therapy as a model
