Active clinical trials for "Colitis"

Background There are no prospective trials comparing the two main reconstructive options after colectomy for Ulcerative colitis, ileal pouch anal anastomosis and ileorectal anastomosis. An attempt on a randomized controlled trial has been made but after receiving standardized information patients insisted on choosing operation themselves. Methods Adult Ulcerative colitis patients subjected to colectomy eligible for both ileal pouch anastomosis and ileorectal anastomosis are asked to participate and after receiving standardized information the get to choose reconstructive method. Patients not declining reconstruction or not considered eligible for both methods will be followed as controls. The CRUISE study is a prospective, non-randomized, multi-center, controlled trial on satisfaction, QoL, function, and complications between ileal pouch anal anastomosis and ileorectal anastomosis. Discussion Reconstruction after colectomy is a morbidity-associated as well as a resource-intensive activity with the sole purpose of enhancing function, Quality of Life and patient satisfaction. The aim of this study is to provide the best possible information on the risks and benefits of each reconstructive treatment.

The purpose of this study is to determine if a sustainable non-elemental diet can be used as a probiotic tool to alter the dysbiotic microbiome found in individuals with ulcerative colitis and thereby decrease disease activity.

The study is on indefinite HOLD due to the loss of funding that occurred during the pandemic emergency. Subsequently, a key collaborator left our institution, and as a near-term result, the protocol awaits reactivation. Three patient subjects were enrolled, all 3 patients/subjects were cured of the infection, and there were no adverse events or sequelae observed or reported. The aim of the study continues to confirm and extend the work of Trede and Rask-Madsen (Lancet 1989;1:1156-1160) that administration of a defined fecal microbiota will lead to rapid and sustained resolution of C. difficile-associated chronic relapsing diarrhea. FDA required 4 non-geriatric qualified patients to be studied before including the elderly. However, C. difficile-associated chronic relapsing diarrheal illness is predominantly a disease of the elderly, so this requirement GREATLY impeded timely enrollment. No protocol deviations have occurred. The current rationale behind FMT for CDI is that the introduction of microbes from a healthy donor should allow for the restoration of a normal microbial community in the diseased host with consequent suppression of C. difficile colonization and disease pathogenesis. The first modern use of FMT was reported in a 1958 case series of 4 patients with pseudomembranous enterocolitis. The first case of confirmed CDI treated with FMT was reported in 1983; treatment was curative. Until 1989, retention enemas were the most common technique for FMT. Alternative methods for delivering FMT have included fecal infusion via duodenal tube (1991), rectal tube (1994), and colonoscopy (1998). FMT for recurrent CDI has been used successfully, whether administered by nasogastric tube, rectal administration by colonoscopy, or rectal tube, including self-administration at home by enema. FMT has proven to be remarkably effective and remarkably safe without any significant problems (see below and attached reviews and meta-analyses). Increasing interest is emerging regarding the changes in the intestinal microbiota associated with CDI. In 2008 Chang et al. constructed small (< 200 sequences per subject) 16S rRNA gene libraries from the stools of 4 patients with first-time CDI and 3 patients with recurrent CDI. Based on 16S rRNA gene classification, they found that the fecal microbiomes of patients with an initial episode of CDI were similar at the phylum level to healthy subjects (i.e., the majority of sequences belonged to dominant fecal phyla Bacteroidetes and Firmicutes), while a major reduction or loss of Bacteroidetes was observed in patients with recurrent CDI. The loss of the Bacteroidetes was accompanied by the expansion of other phyla, including Proteobacteria and Verrucomicrobia, which are normally minor constituents of the fecal microbiota. Khoruts et al. (2010) compared the microbiota of a patient with recurrent CDI before and after FMT by using terminal-restriction fragment length polymorphism and clone-based 16S rRNA gene sequencing. Before transplantation, the patient's microbiota was deficient in members of Bacteroides and instead was composed of atypical fecal genera such as Veillonella, Clostridium, Lactobacillus, Streptococcus, and unclassified bacteria similar to Erysipelothrix. Two weeks after the infusion of donor fecal suspension, the bacterial composition of her feces approached normal and was dominated by Bacteroides sp. strains. In 1989, Tvede and Rask-Madsen used a combination of nine normal fecal organisms to treat 6 patients with chronic relapsing C. difficile diarrhea. These investigators cultivated 10 strains of bacteria, including Enterococcus (Streptococcus) faecalis (1108-2), Clostridium inoculum (A27-24), Clostridium ramosum (A3I-3), Bacteroides ovatus (A40-4), Bacteroides vulgatus (A33-14), Bacteroides thetaiotaomicron (A33-12), Escherichia coli (1109), E. coli (1108-1), Clostridium bifermentans (A27-6), and Blautia producta (Peptostreptococcus productus) (1108-2) in broth for 48 h to a concentration of approximately 10 to the 9th power bacteria/mL. Two mL from each bacterial culture were admixed with 180 mL saline that had been pretreated in an anaerobic chamber for 24 h; the bacterial suspension was then instilled rectally. This procedure was followed promptly by a decline of C. difficile to undetectable levels by culture and the loss of detectable toxin from the stools. Normal bowel function was restored within 24 hours, and abdominal symptoms disappeared. Stool cultures and toxin assays for C. difficile remained negative during a year of follow-up. It is especially important to note that feces from none of the 6 patients contained Bacteroides sp.

This phase II trial studies the effect of atorvastatin in treating patients with ulcerative colitis who have a dominant-negative missense P53 mutation and are at risk of developing large intestinal cancer. Patients with ulcerative colitis are known to have an increased risk of developing large intestinal cancer. Better ways to control ulcerative colitis and more knowledge about how to prevent colon cancer are needed. Atorvastatin is a drug used to lower the amount of cholesterol in the blood and to prevent stroke, heart attack, and angina (chest pain). It blocks an enzyme that helps make cholesterol in the body. It also causes an increase in the breakdown of cholesterol. The information gained from this study may help doctors learn more about atorvastatin as an agent in cancer prevention, and may help to improve public health.

Inflammatory bowel diseases (IBD), which include Crohn's disease (CD) and ulcerative colitis (UC), are chronic immune-related diseases. IBD symptoms frequently overlap with symptoms of functional GI disorders such as irritable bowel syndrome (IBS) and defecatory disorders, and these symptoms are common in patients with active disease, and also in quiescent disease. Underdiagnosis of abnormal anorectal function may result in an inappropriate escalation of IBD therapy. In this study, the investigators aim to evaluate if damage from chronic inflammation in UC results in anorectal damage such as hypersensitive, hyperactive, poorly compliant rectum, and hypotensive sphincter. If this is the case, early aggressive treatment of the disease is needed. Another important point in this study is to find out which of the anorectal symptoms are due to a hypersensitive, hyperactive, and poorly compliant rectum and not due to mucosal inflammation. The diagnosis of abnormal anorectal function via manometry may help to give the appropriate treatment, such as biofeedback or pharmacological treatment such as loperamide or tricyclic anti-depressants. This may avoid escalation or replacing effective IBD therapy unnecessarily.

PHASE: IV DESCRIPTIVE: Randomized, interventional, open label multicenter trial POPULATION: Moderate to severe ulcerative colitis STUDY TREATMENTS: Patients will all receive Adalimumab 160/80/40mg EOW until V1 (W14) followed by 40mg EOW until V2 (W26) and could be optimized up to 80mg EOW (or 40 EW according to patient and/or investigator preference) for two months and then could be optimized up to 80mg EOW (or 40 EW according to patient and/or investigator preference) and azathioprine (2.0/2.5 mg/kg/ day) or methotrexate (25 mg EW) until V3 (W 38). OBJECTIVES: To assess the impact of a treat to target treatment follow up by e-Monitoring and fecal calprotectin dosing at home associated to an appropriate patient education versus standard treatment follow up at W48 in patients requiring a treatment with adalimumab (Humira®).

This is a small pilot study of the fermented soybean extract MicrSoy-20(MS-20) to confirm its ability to improve UC severity with the treatment of standard therapies. The primary endpoint, structural alteration of gut microbiota during the trial will be analyzed. Secondary endpoints aim to observe the changes of partial Mayo score, patient response of medication of UC treatments, biomarker changes in blood, and safety after taking MS-20.

Prospective, single-center, sham-controlled, double-blinded 12-week study designed to evaluate the safety and efficacy of the RAVANS device in subjects with Ulcerative Colitis. The goal of the study is to distinguish sham (no stimulation) versus treatment (stimulation) response and to identify treatment responders. The study will last 12 weeks with in-clinic visits at 0 weeks and 12 weeks, and a telehealth-visit at week 6. Additionally, unscheduled visits may occur based on the needs of the subject or at the discretion of the investigator. Subjects will be randomized 2:1 to treatment or sham, and will stimulate at home twice per day.

This study examines how a fermentable dietary fibre known to promote butyrate production impacts intestinal barrier function, intestinal microbiota, intestinal inflammation, and gastrointestinal symptoms in patients with microscopic colitis.

The purpose of this study is to determine if Aquamin® works as a potential treatment to improve symptoms and if it will induce remission in patients with mild Ulcerative Colitis and extend remission in Ulcerative Colitis in remission.
