NCT ID: NCT04985981 Suspended - Colorectal Cancer Clinical Trials

The Prediction of Anastomotic Insufficiency Risk After Colorectal Surgery (PANIC) Study

Start date: April 1, 2021
Phase:
Study type: Observational [Patient Registry]

The Prediction of Anastomotic Insufficiency risk after Colorectal surgery (PANIC) study aims to establish a machine-learning-based application that allows for accurate preoperative prediction of patients at risk for anastomotic insufficiency after colon and colorectal surgery.

NCT ID: NCT04225819 Suspended - Ulcerative Colitis Clinical Trials

Adjunctive Treatment With Vitamin D3 in Patients With Active IBD

ACTIVATED
Start date: October 1, 2020
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04143490 Suspended - Ulcerative Colitis Clinical Trials

Effects of Exercise in Patients With Ulcerative Colitis

Start date: November 4, 2019
Phase: N/A
Study type: Interventional

The aim of this study is to investigate the effects of moderate to high intensity exercise on gut function and inflammatory markers in patients with Ulcerative Colitis (UC), and to compare them with individuals of matched age who do not suffer from Inflammatory Bowel Disease. Participants will be asked to complete 60 minutes of continuous cycling at a moderate to high intensity followed by a three hour recovery period. Gastrointestinal function will be measured using a non-invasive breath test. Blood samples will be collected at multiple time-points during the visit and these samples will be measured for markers of immune function and intestinal integrity.

NCT ID: NCT03358706 Suspended - Ulcerative Colitis Clinical Trials

A Study to Evaluate the Effect of Ustekinumab on Cytochrome P450 Enzyme Activities Following Induction and Maintenance Dosing in Participants With Active Crohn's Disease or Ulcerative Colitis

Start date: February 2, 2018
Phase: Phase 1
Study type: Interventional

The purpose of this study is to evaluate the potential effects of an intravenous (IV) induction and subcutaneous (SC) maintenance administration of ustekinumab on the pharmacokinetic (PK) of a cocktail of representative probe substrates of cytochrome P450 (CYP) enzymes (CYP3A4, CYP2C9, CYP2C19, CYP2D6, and CYP1A2) in participants with Active Crohn's disease (CD) or Ulcerative Colitis (UC).

NCT ID: NCT02361957 Suspended - Ulcerative Colitis Clinical Trials

The Effect of the Multispecies Probiotic Ecologic 825 Versus Placebo in Ulcerative Colitis Patients

CUPIDO
Start date: November 2014
Phase: N/A
Study type: Interventional

RATIONALE: The underlying etiology in inflammatory bowel diseases such as Ulcerative Colitis is not yet fully understood. Studies suggest a relation between higher intestinal permeability and aberrant changes of the epithelium. Dysbiosis of the intestinal microbiota might be the cause. Probiotics may restore the balance of the intestinal microbiota. In theory this could improve intestinal permeability and therefore reduce disease activity and maintain remission in patients with Ulcerative Colitis. OBJECTIVE: To investigate whether a specifically designed multispecies probiotic mixture (ecologic 825®), as adjuvant therapy, can contribute to an improvement of intestinal permeability, microbiota composition, disease activity and inflammatory markers in ulcerative colitis. STUDY DESIGN: 12-wk placebo-controlled randomized double-blind intervention with 2 parallel arms. STUDY POPULATION: Adults diagnosed with left sided Ulcerative Colitis or Pancolitis in remission or mild stage of the disease. For inclusion of the patients the Patient Simple Clinical Colitis Activity Index (P-SCCAI) will be used. INTERVENTION: Patients will receive either two daily dosages of 3 g of Ecologic® 825 or two daily doses of 3 g of the placebo, containing only the carrier material (both produced by Winclove Probiotics). MAIN STUDY PARAMETERS/ENDPOINTS: Main study parameter is intestinal permeability measured by several techniques: the lactulose/mannitol absorption test (L/M test), LPS levels in blood serum and faecal zonulin. Secondary, inflammation will be measured from faecal calprotectin and blood c-reactive protein (CRP) levels. Furthermore samples will be stored to measure cytokine concentrations in serum and to analyse the microbial composition of the faecal samples using the HITchip. For the disease related quality of life the irritable bowel disease questionnaire (IBD-Q) and SF-36 will be used. All parameters will be measured at three time points; t=0, t=6 and t=12 weeks.
