Active clinical trials for "Colitis"

Aim of the work To identify the prevalence of CMV infection in patients with steroid-refractory ulcerative colitis. To assess the clinical and endoscopic conditions in these patients.

This is a prospective observational cohort study, over 52 weeks, evaluating the the use of faecal microbiota transplantation amongst patients with Inflammatory Bowel Disease and Microscopic Colitis

Graves disease in ulcerative colitis: The connection between Graves disease and Inflammatory bowel disease is well known in the literature, but thyroid disorders have not been considered extra-intestinal manifestations of ulcerative colitis. In most cases, the diagnosis of thyroid disease has preceded that of Inflammatory bowel disease. Early studies have suggested a relationship between thyroid abnormalities and ulcerative colitis . But it is still uncertain whether the coexistence of Grave's and ulcerative colitis diseases is due to a specific reason or a coincidence.

Background theme Crohn's disease (CD) and ulcerative colitis (UC) are chronic diseases that alternate flares of active inflammation with periods of clinical remission. The working capacity of patients may be affected both by disease activity and by the aggressive treatment or surgical intervention required for the management of the disease and its complications. Work disability and impairment are especially important in patients with inflammatory bowel disease (IBD) because the disease affects young individuals who are generally employed and fully active. Although there are several indexes in the literature that assess the degree of work disability due to IBD, all have a high degree of subjectivity, so none can be used to request disability pensions. Experience of the research group on the subject Our group has developed a line of research on work disability associated with IBD. Initially the investigators have studied the parameters that condition the granting of disability pensions of Spanish courts. Subsequently, a population study of the prevalence of work disability in Spain has been carried out. Finally, the investigators develop and validated a disability index for CD (published in its extensive and reduced form) and for UC (currently under review). Hypothesis The IBD generates a work disability that can be measured objectively. Establishing the parameters related to disability is essential to promote equity in administrative and judicial decisions related to the granting of disability pensions to patients with IBD. Objective Development and validation of an objective index to measure the degree of disability in IBD. Material and methods: Study 1: A self-reported and objective questionnaire of disability will be developed based on the data of the population survey already carried out by our group. Patients from a previous study (n 293) will be included. The relationship of different objective variables and disability outcomes will be analyzed with a univariate and a subsequent multivariate analysis. Alternative work disability scores will be developed. Study 2: for the validation of the questionnaire a new online interview will be performed, patients from patients' assocations will be asked to participate. Data Collection: patients will answer a online survey administered with the SurveyMonkey © platform. Participant will answer questions about demographics, disease activity, treatment and complications and data regarding disability. Patients will also complete the SCDWDQ (Short Crohn's Disease Work Disability Questionnaire), Work Productivity and Activity Index (WPAI), IBDQ-9, the EuroQol and IBD-DI (IBD disability index). Statistical analysis: psychometric properties of the index will be evaluated: Convergent validity: the Spearman correlation will be used to correlate the objective disability score with IBD-DI and SCDWDQ. Discriminant validity: it will be measured by the t-test among patients with different degrees of disability (inactive-active, hospitalization-no hospitalization, surgery-no surgery).

Observational prospective multicenter study: baseline assessement of the disease activity by an automated endoscopic tool and follow up of 52 weeks to evaluate sustained clinical remission.

Probe-based confocal laser endomicroscopy (pCLE) is an endoscopic technique that enables to evaluate the inflammation activity of ulcerative colitis with excellent correlation with histopathology. However this requires much experience, which limits the application of pCLE. The investigators designed a computer-aided diagnosis program using deep neural network to make diagnosis automatically in pCLE examination and contrast its performance with endoscopists.

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding Ulcerative Colitis

Describe the proportion of patients with ulcerative colitis (UC) treated with vedolizumab (VDZ) who achieve mucosal healing at week 54 of treatment.

Molecular imaging with infliximab antibody with FITC has the potential to predict therapeutic responses to infliximab antibody and can be used for personalized medicine in ulcerative colitis.

Mucosal healing or histological remission is an important target for the treatment of inflammatory bowel disease. In this study, patients with mucosal healing are defined as a control group, observing their clinical outcomes for 3 years, and describing the recurrence rate. The secondary objective is to study the operative rate, glucocorticoid utilization rate, treatment escalation rate, hospitalization rate and incidence of related complications.
