Active clinical trials for "Colitis"

The purpose of this study is to evaluate the engraftment of donor microbiota's sulfate reducing bacteria (SRB) in subjects with active ulcerative colitis (UC) following sequential fecal microbiota transplant (FMT). Specifically this study will evaluate if low SRB donor microbiota translates to lower SRB microbiota in the UC recipient. It is widely unknown if the microbiota in UC is dysfunctional and therefore perpetuates inflammation, or if the ongoing inflammation shapes the microbiota. Patients with UC have a higher relative abundance of SRB compared to healthy controls. It is the aim of this study to determine if the microbiota in UC can be altered to favor a low SRB fraction.

The overarching goal of this study, is to create a longitudinally followed, well phenotyped cohort of patients with UC starting treatment with tofacitinib in the setting of standard of care who have linked clinical data and self-reported outcome data that will lead to evaluation of efficacy and safety of tofacitinib in the real-life setting. The specific aims for the study are: Create a prospective cohort of well phenotyped (proctitis vs. rectosigmoiditis vs. extensive) adult UC patients with serial clinical and patient-reported data collected throughout the course of 12 months of tofacitinib therapy. Enrolled patients on therapy will be followed up to 36 months after the start of therapy. To determine clinical response rates and persistence of therapy with tofacitinib for induction and maintenance therapy Describe the incidence of specific drug-associated adverse events (shingles, serious infections), hospitalizations and surgeries in the standard of care setting. Assess the correlation of various outcome measures in ulcerative colitis (Simple Clinical Colitis Activity Index (SCCAI), partial Mayo index, 6-point index) and endoscopic outcomes via the endoscopic Mayo Score

The objective of this quality improvement project is to increase the one year anastomotic integrity rate in patients having had completion proctectomy and pouch reconstruction for Ulcerative Colitis by the routine and quality controlled implementation of a multi-interventional program thereby improving long-term pouch function and survival.

Inflammatory bowel disease ((IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC)), is a chronic, immune-mediated disease characterized by recurrent episodes of relapse. The incidence of IBD is increasing worldwide and poses as a burden that reduces quality of life and has a significant impact on health care resources. The advent of monoclonal antibodies to tumor necrosis factor-α (anti-TNF) has revolutionized treatment of IBD, improving rates of remission and reducing hospitalizations and surgeries. Nevertheless, many patients do not adequately respond to these therapies or lose response over time. Thus, there is an important need for novel immunomodulating agents to improve our ability to achieve remission. Besides its traditional role in bone homeostasis, several studies have recognized the important role Vitamin D plays in modulating the immune response, cancer, and cardiovascular disease. Specifically, Vitamin D may mediate immunity by modulating autophagy in leukocytes and regulating the gut microbiome. Thus, Vitamin D may play an important role in IBD. Furthermore, evidence suggests that the effect of vitamin D may be mediated through the TNF-α pathway, suggesting a synergy with anti-TNF therapy. This is a randomized, double blind, placebo-controlled trial to study the effect of Vitamin D3 as an adjunct therapy for patients with active CD, UC, or IBD unspecified who are undergoing anti-TNF induction therapy.

Participants who are in clinical remission on 200 mg filgotinib once daily (q.d.) for at least 2 consecutive quarterly visits in the ongoing SELECTION-LTE study (GS-US-418-3899, NCT02914535), are planned to be rolled over and randomized in this study. The primary objective of this study is to evaluate the efficacy of filgotinib in participants in stable clinical remission on 200 mg filgotinib q.d. for whom the dose was decreased to 100 mg q.d. compared to participants remaining on 200 mg q.d.

To determine whether symptomatic treatment of the diarrhea in CDAD reduces morbidity and mortality of this serious nosocomial infection in patients who have antibiotic-associated diarrhea. Both C. diff positive and negative patients will be included.

In patients achieving clinical remission following a flare, artificial intelligence can reliably predict a new flare within the next 12 months utilizing clinical and objective information at day 0 and week 8. Secondary endpoints: An artificial intelligence model's precision in predicting a new flare within 2 and 3 years An artificial intelligence model's precision to rule out patients who will not experience a new flare within 1, 2 and 3 year

The purpose of this study is to evaluate the incidence, prevalence, clinical characteristics and prognosis of Crohn's disease and ulcerative colitis over time in a district of Seoul, Korea.

Constitution of a biobank of tissues, whole blood and plasma samples and stools to identify markers associated with treatment response, postoperative morbidity including neuro-cognitive and mood complications and prognosis of Inflammatory Bowel disease or colorectal cancer.

The investigators hope that the present study will highlight new transcriptomic prognostic markers of response to Ustekinumab with the ultimate goal of individualizing treatment and making a more targeted selection of UC patients who will benefit from this biological agent.
