Active clinical trials for "Colitis, Ulcerative"

Ulcerative colitis (UC) is an inflammatory disease involving the colonic mucosa, with bleedings and ulcerations. Consequences are destroyed mucosal barrier and increased permeability. Several cytokines are described to mediate the progressive course of ulcerative colitis and it is considered nowadays an immunologic disease. Patients with UC have often low levels of vitamin D and elevated prevalence of osteoporosis. In vitro studies demonstrate that vitamin D has an immunomodulating effect, and may have a direct healing action on colonic mucosa has been described in animal studies. One can therefore rise a hypothesis that vitamin D supplementation could be crucial in patients with UC. To our knowledge, it has not been performed randomized clinical trials to study these possible effects of vitamin D and it has not been studied the effects of vitamin D on the relapse frequency and immunological composition of colic mucosa in patient with moderate to severe ulcerative colitis. Objectives for our study are as follows: To examine if high-dose vitamin D supplementation in patients with moderate to severe ulcerative colitis: reduces relapse frequency and increase the duration of the Infliximab induced remission mediates and changes the cytokines composition in the colic mucosa decreases the excretion of calprotectin in feces and reduces the concentration of inflammation markers augments bone mass

In this study, the investigators aim to evaluate the role of intestinal ultrasound in evaluation of the therapeutic response to biological therapy in patient with ulcerative colitis

Rationale: Existing literature suggests an impaired health-related physical fitness (HRPF) (i.e., body composition, aerobic capacity, muscular strength, muscular endurance, and flexibility) in patients with inflammatory bowel disease (IBD). However, previous studies did not assess HRPF with the 5- component multidimensional concept. HRPF is not routinely screened for and measured within the IBD population in clinical practice. The lack of a simple screening tool and assessment method for HRPF validated for the IBD population hinders the ability to distinguish patients with IBD with adequate physical fitness from those who might benefit from physical exercise interventions targeting specific components. Gold standard measures are too expensive and too complex to implement in daily practice and therefore a screening tool and a simpler assessment battery for HRPF validated in patients with IBD are needed. It is necessary to obtain more objective insights into the specific components of HRPF affected in patients with IBD, and its association with patient-, disease-, and treatment-related factors in order to implement systematic screening in routine care and subsequently offer tailored physical exercise interventions. Objective: The main objective of this study is to validate a simple screening tool and a best-practice assessment battery for the different components of HRPF against gold standard measures. Secondary objectives are to objectively assess the incidence of specific components affected in patients with IBD compared to healthy control subjects and to explore the association between these components of HRPF affected and patient-, disease-, and treatment-related factors.

The purpose of this study is to evaluate association between ozanimod exposure during pregnancy and subsequent maternal, fetal, and infant outcomes.

This will be a prospective, multi-center, randomized, single blind study to collect and evaluate post-market clinical data on the SprayShield Adhesion Barrier System as an adjuvant to good surgical technique for the reduction of postoperative adhesion formation following major open abdominal surgery.

Aim of study: Primary Outcomes: Patients with ulcerative colitis-associated upper gas- trointestinal inflammation may require specific treat- ment for the gastroduodenal lesions. Hence, recogni- tion and detection of the upper gastrointestinal lesions are important. Here we describe 2 cases of ulcerative colitis and summarize the results of our investigation of the prevalence of upper gastrointestinal involvement detected by esophagogastroduodenoscopy. We also analyzed the macroscopic and microscopic features of the upper gastrointestinal lesions Secondary Outcomes: correct and timely treatment of upprt GIT lesions in UC .

A diagnostic tool that identifies biomarkers that predict response prior to and during induction of ozanimod will have a major impact on improving outcomes in UC patients. Using SOMAscan from SomaLogic (Boulder, CO), our study aims to discover serum protein biomarkers in UC patients that predict response to ozanimod and to gain insight into the pathophysiological mechanisms underlying ozanimod response.

The purpose of this clinical study is the development of physiologic endpoint of inflammation in pediatric patients diagnosed with inflammatory bowel disease (IBD), specifically subtypes Crohn's disease (CD) and ulcerative colitis (UC). The novel medical device evaluates the patient's sensory response to each of the three sensory nerve fiber types. Data from the device provides an assessment of disease activity and a more precise approach to treatment.

The purpose of this research study is to determine whether starting the drug vedolizumab earlier than its FDA approved use can lead to better control of UC then using older drugs that we have historically used to treat UC. Vedolizumab is FDA-approved to be used after initial Corticosteroid treatments have failed or other UC treatments have failed. We will study if using vedolizumab as an early treatment for your UC will allow you to get off corticosteroids and prevent UC from worsening and requiring surgery. Vedolizumab is given intravenously initially every 2 weeks and then every 8 weeks.

Crohn's disease and Ulcerative colitis are chronic disease that are usually diagnosed at young age. The diseases and the associated treatment can impact on patient's sexual function, fertility, pregnancy, and delivery. This study aims to assess the impact of inflammatory bowel diseases on these aspects in female patients.
