Filter by:Objective: To use clinical, genetic and genome analysis to better understand and define the genetic and environmental factors that contribute to IBD in diverse ancestries: African, African American, Black, Afro-Caribbean, Afro-Latino/a/x, Latino/a/x, Hispanic, or any other Black or Latin or indigenous ancestry.
Anti tumor necrosis factor (TNF agents), particularly infliximab and adalimumab, changed the way chronic inflammatory bowel disease (IBD) refractory to conventional therapies is treated, including in pediatric patients. However, approximately 10-30% of patients do not respond to initial therapy and up to 50% lose response over time. Variability in response to therapy may be influenced by multiple interacting factors at different levels. Recent studies showed that measurement of serum infliximab concentrations during induction therapy predicts treatment effects at one year. Therefore, therapeutic monitoring of infliximab is proposed as a useful strategy to improve clinical outcomes and optimize healthcare resources. Most commercially available methods for infliximab quantification are based on the ELISA assay, which has an assay time of at least 8 hours. Recently, commercial point-of-care devices became available with assay times of less than one hour, enabling real-time therapeutic drug monitoring; however, validation of these devices in clinical settings and comparison with standard assays are still needed, particularly in pediatric patients. In addition, some studies suggest that loss of response in patients treated with anti-TNFs may be partly due to the emergence of specific anti-drug antibodies (AAFs). A limitation of the most widely used ELISA assays is the inability to quantify drug and AAF when they are simultaneously present. Recently, innovative ELISA assays have become available to overcome this problem. However, there is a lack of comparative studies between the classical and the specific method in terms of clinical response in pediatric patients. In patients who do not respond to infliximab, especially if they have high levels of AAF, guidelines call for the use of adalimumab. For this drug, the evidence in the literature regarding therapeutic monitoring of adalimumab concentrations and association with response in pediatric patients is still very preliminary. This study, carried out in in pediatric patients with IBD, aims to: 1. validate the "point of care" infliximab assay by comparing it with reference ELISA assays; 2. evaluate the correlation of infliximab and AAF levels, as measured by the innovative ELISA assays, with response to therapy, compared to traditional assays. 3. evaluate the association between adalimumab and AAF levels and response to therapy
Inflammatory Bowel Disease (IBD) includes a group of chronic inflammatory conditions of the gastrointestinal system and is composed of Crohn's disease and ulcerative colitis. As an immune-mediated disease, IBD treatment options include the use of biologic medicines including anti-tumor necrosis alpha factor (also called anti-TNFs) medication. Despite biologic medicines being an important part of IBD management, there is inconsistency in the way these medications are used. Implementation of evidence-based, standardized biologic care pathways (BCP) can improve treatment related outcomes. Previous research has shown that using a clinical care pathway, such as a BCP, is a feasible method to support clinical decision making and may improve disease-related outcomes for patients. The researchers propose a prospective study to determine how well a BCP can be incorporated into clinical practice, improve patient health outcomes, and reduce healthcare system redundancies. Also, the impact of a BCP on outcomes for patients treated with the help of a standardized BCP compared to those in patients treated without the use of a BCP will be studied. The results of this study will inform how best to incorporate evidence-based BCPs into real-world practice and support the wide-spread adoption of BCPs in clinical practice.
Primary sclerosing cholangitis (PSC) is a progressive disease of the biliary tree, which represents one of the most frequent indications for orthotopic liver transplantation (OLTx) in developed countries. There are several lines of evidence that dietary gluten/gliadin displays chronic pro-inflammatory, LPS-like properties. Recent evidence demonstrated the protective effect of gluten- free diet (GFD) in autoimmune diseases like type 1 diabetes, irritable bowel syndrome, non-celiac gluten sensitivity and some neurological disorders. This study is intended to explore therapeutic effect of GFD on PSC and IBD in prospective self-controlled mono-centric intervention study. Hypothesis: Avoidance of gluten in diet will reduce progression, symptoms and intestinal inflammation in PSC and UC patients.
The goal of this cross-sectional study was to explore the relationship between physical and psychological stress and the quality of bowel preparation before a colonoscopy examination, in order to improve the quality of bowel preparation. The main questions it aims to answer are: Does physical and psychological stress affect the quality of colonoscopic bowel preparation, and delay disease detection? How can we improve the quality of colonoscopy？ Participants will be asked to complete a questionnaire containing their demographics, history of diseases and drugs, lifestyle habits, and physical and 14-item perceived stress scale(PSS-14). Quality of bowel preparation was assessed by the Boston bowel preparation scale（BPS）.
This research study is being done to look at the impact of a Stress Management and Resilience Training (SMART) Program on the quality of life and healthcare utilization of patients with inflammatory bowel disease.
Apart from its use to provide insight in IBS disease courses and in clinical research, ESM can provide patients with feedback about individual triggers of their symptoms, and thereby function as part of a personalized therapeutic strategy. This is also true for IBD-IBS. Treatment strategies in IBS and IBD-IBS are largely based on reassurance, identification and elimination of triggering factors, and in more severe cases pharmaco- and psychotherapy. The ESM approach has the potential to increase therapeutic efficacy in IBS and IBD-IBS and will assist patients in disease self-management. The Traqq application can provide more detailed information about the dietary pattern of IBS and IBD-IBS patients. Traqq in combination with ESM will give an overview of abdominal pain and associated symptoms and psychosocial factors are exposed to during the day. The insight provided using ESM and Traqq may improve patient understanding of their personal symptom dynamics and triggers, as well as the physician's insight into the symptom patters of the specific patients, which may aid treatment choice and eventually improve the outcome of any treatment provided in daily clinical care.
The role of intestinal ultrasound in treatment monitoring has recently gained increasing interest thanks to its non-invasiveness, cost-effectiveness and largely availability. Moreover, new ultrasonographic tools, particularly dynamic contrast-enhanced ultrasound (D-CEUS) and shear wave elastography (SWE) can provide further useful information, such as a quantitative estimation of bowel intramural microvacularization and tissue stiffness. Aim of this study is to evaluate the role of D-CEUS and SWE in predicting deep remission at 12 months from treatment induction in IBD.
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.
