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.
The goal of this clinical trial is to determine the outcome of patients with immune checkpoint inhibitor-mediated diarrhea/colitis (IMC) treated with faecal microbiota transplantation (FMT) in a randomised, placebo-controlled trial. The aim of the present study is to assess the feasibility, pilot efficacy, and safety of FMT for patients with IMC. Participants will be treated two times with capsule FMT or placebo capsules in a 1:1 ratio. The intervention treatment will be an add-on to the patients' standard treatment for IMC. Researchers will compare the FMT-treated group to the placebo-treated group to see if FMT promotes remission of IMC.
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.
Microscopic colitis (MC) is an inflammatory bowel disease characterized by chronic non-bloody watery diarrhoea and a macroscopically normal colonic mucosa upon endoscopic exploration (colonoscopy). The diagnosis is performed by microscopic examination of mucosal biopsies that reveal specific histopathological change. Between 4-20% of patients with chronic non-bloody diarrhoea who undergo colonoscopy with serial biopsies are diagnosed with MC. It has long been hypothesized that the microbiome plays a key role in the pathogenesis of MC. In patients with collagenous colitis, faecal stream diversion results in inflammation and histological remission, followed by disease relapse after intestinal transit is reconstructed. Moreover, studies carried out with faecal samples obtained after colonoscopy have demonstrated microbiome changes (reduced alpha diversity and higher microbial dysbiosis index) in patients with active MC. To avoid potential bias due to the effect of colonic lavage prior to colonoscopy in microbiota composition, the researchers of the present study previously evaluated the microbiome in faecal samples obtained before the diagnostic colonoscopy in patients with active MC. The results confirmed a reduced alpha diversity in diarrhoea groups; however, there were no differences between MC, bile-acid diarrhoea and functional diarrhoea. The microbial dysbiosis index was significantly higher in MC compared to the other diarrheal groups, but no bacterial species showed a significantly different relative abundance. On the other hand, the risk of colorectal cancer (CRC) or adenoma seems to be reduced in MC compared to controls. Growing evidence suggests microbial dysbiosis is a crucial environmental factor in the initiation of precancerous lesions of CRC such as adenomas. The objective of the current multicentric prospective study is to assess the differences in the mucosa adherent intestinal microbiome between patients with MC, non-MC chronic diarrhoea, healthy controls and patients with advanced colon adenomas. In addition to the study of the microbiome, sociodemographic variables, history of drug usage, diets and specific characteristics of diarrhoea will be collected. The hypothesis of the present study is that CM presents a specific mucosa adherent intestinal bacterial profile that may be relevant in the pathogenesis of the disease and that, additionally, may also play a protective role against the development of CRC and adenomas.
