Filter by:Ulcerative Colitis (UC) is a chronic Inflammatory Bowel Disease characterized by chronic inflammation of the colon. Composition of gut microbiota of UC patients is abnormal (dysbiosis). Ulcerative Colitis patients have an increased risk of Clostridioides difficile infection (CDI) and CDI complications (colectomy, death, recurrence). The reason for this increased risk in IBD patients is not fully understood. The decrease in the proportion of secondary bile acids, induced by microbiota dysbiosis in patients with UC could favor C. difficile infection. The main objective of the study is to describe the composition of bile acids (primary and secondary) in children followed for UC during relapse with or without CDI and to compare it to children with UC in remission and healthy controls. The composition of fecal microbiota will be also describe to correlate dysbiosis and bile acid abnormalities. And finally some fecal biomarkers will be study : short chain fatty acids, metabolic pathway of Tryptophan, and fecal Calprotectin.
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 compare the safety and efficacy of nicotinamide mononucleotide (NMN) and placebo in patients with mild ulcerative colitis (UC). The main question it aims to answer is Whether NMN can alleviate the intestinal pathology of UC patients, so as to play a role in UC treatment or adjuvant therapy. Participants will be randomized into two groups, an NMN group or a placebo group. Patients in the NMN group were treated with NMN intervention for 8 weeks. The placebo group received a placebo intervention for 8 weeks.
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.
Ulcerative colitis (UC) is considered a subcategory of inflammatory bowel disease and the exact cause of ulcerative colitis remains undetermined. the condition appears to be related dysregulated immune response and consequent activation of inflammatory cascades, which are often affected by genetic susceptibility and environmental factors, and 20% to 40% of patients with UC also exhibit extraintestinal manifestations involving the joints, skin, eyes, or hepatobiliary tract
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.
A randomised, double-blind, double-dummy, multicentre, phase III, non inferiority trial of an oral mesalazine formulation in patients with active mild to moderate ulcerative colitis for the induction of remission.
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)
