Filter by:A prospective observational study to assess the energy needs of Ulcerative Colitis patients undergoing total proctocolectomy with ileoanal j-pouch anastomosis.
The goal of this clinical trial is to evaluate the possible beneficial effect of silymarin in Ulcerative Colitis adult patients receiving mesalamine. This is trial that will be conducted on 44 adult patients with newly diagnosed Ulcerative Colitis. Patients will be enrolled after obtaining an informed consent from them or their guardians. Patients will be recruited from Rajhy Hospital Outpatient Clinics and Health Insurance Outpatient Clinics at Mabarra Hospital in Assiut, Egypt. The patients will be randomized based on hospital admission days into two groups: - Group Ⅰ (control group): 22 patients will receive mesalamine (4g\day induction & 2g\day maintenance) only for 6 months. - Group Ⅱ (silymarin group): 22 patients will receive mesalamine (4g\day induction & 2g\day maintenance) and silymarin (140 mg\day) for 6 months. The primary outcome will be clinical improvement defined as a 2 point or more decrease in the Mayo score from baseline. The secondary outcomes will be the change in the level of fecal calprotectin, superoxide dismutase and TNF-α.
First-in-human study to provide an assessment of the safety, tolerability, pharmacokinetics (PK), including food effects and a drug-drug interaction, and pharmacodynamics (PD) of OD-07656 after administration of ascending single and multiple oral doses to healthy male and female participants in view of treating inflammatory bowel disease (IBD) (including Crohn's disease and ulcerative colitis), Blau syndrome, and spondyloarthritis
The ULTRAZ study is designed to better understand the mode of action of S1P receptor modulators. The alteration of leukocyte trafficking due to S1P receptors such as ozanimod is mainly investigated in rodent studies. Several previous studies show a reduced total leukocyte count in peripheral blood and only two study reported the effect of leukocyte subgroups before and after treatment with ozanimod. The change in leukocyte subgroups in peripheral blood as well as colonic mucosa and lymph nodes have not been investigated to our knowledge. Therefore, the aim of this study is to explore the changes in these three compartments.
1. characterize the response to current medical therapy in adult with ulcerative colitis . 2. Detect prognostic factors of response of biological therapy in adult with ulcerative colitis
The purpose of this study is to evaluate the efficacy, safety, and pharmacokinetics of vixarelimab compared with placebo in participants with moderate to severe UC who have demonstrated inadequate response to, loss of response to, or intolerance to prior conventional or advanced therapy.
ROSETTA STUDY: This study will evaluate the safety, tolerability, and efficacy of Rosnilimab in subjects with moderate to severe ulcerative colitis (UC)
The purpose of this retrospective observational cohort study is to assess pregnancy and infant outcomes in three groups: the first is women with ulcerative colitis (UC) who were exposed to ozanimod during pregnancy; the second is women with UC exposed to conventional therapy during pregnancy; the third is women with UC exposed to advanced therapy during pregnancy. This study will use data from a large US healthcare claims database.
The intestinal epithelial barrier is one of the most important security checkpoints of our body that constrains harmful factors from invading mucosal surfaces and facilitates the absorption of nutrients and water. Its correct functioning is essential for maintaining gut tissue homeostasis and proper immunity. However, such an equilibrium may be interrupted, resulting in an uncontrolled entrance of pathogenic stimuli that in turn activate a persistent gut immune response, with detrimental consequences for both local and systemic immunity. Alterations in the composition and functionality of the gut microbiome seem to be a central factor in affecting gut barrier integrity thus influencing intestinal permeability. The microbiome composition is impacted by dietary habits and environmental pollution and conditions, hygiene, genetic asset, and physical activity, which could interact in concert leading to dysbiosis, thereby influencing the immune response through the production of several metabolites. Chronic inflammatory diseases, including ulcerative colitis (UC) and type 1 diabetes (T1D), share microbiota dysbiosis, among pathologic characteristics, that may arise, be provoked, or be exacerbated because of barrier leakage. Therefore, these two chronic diseases may be considered prototype pathologies where the intrinsic connection between intestinal dysbiosis and the barrier leakage impact each other during the pathogenesis.
Crohn's Disease (CD) and Ulcerative Colitis (UC) are chronic inflammatory bowel diseases (IBD). Adalimumab is a human monoclonal antibody against TNF-alpha, a pro-inflammatory cytokine that mediates the inflammatory response in IBD upon binding to the TNF receptors. Primary non-response to adalimumab is high in both CD and UC. Currently, there are no predictors of response to adalimumab and the actual mechanism of action has not yet been elucidated. To gain better understanding of the drug targeting of adalimumab in IBD, the University Medical Center Groningen (UMCG) developed fluorescently labeled adalimumab (adalimumab-680LT). This study aims to assess the safety and the optimal dose of adalimumab-680LT to visualize and potentially quantify the local drug concentration and predict treatment response in IBD patients using in vivo and ex vivo fluorescence molecular imaging (FMI).
