Active clinical trials for "Colitis"

The purpose of this study is to gain insights in the pharmacokinetics of golimumab in moderate to severe Ulcerative Colitis after subcutaneous administration, during induction and maintenance treatment the investigators will collect blood and stool samples at different time points.

Irritable bowel syndrome is responsible for chronic abdominal pain, diarrhea and/or constipation. It is a very frequent problem. However, the exact cause of irritable bowel syndrome remains unknown. The purpose of this study is to look for a different cerebral response by magnetic resonance imaging after rectal stimulation in patients with irritable bowel syndrome compared to healthy subjects and to patients with digestive organic disease. Our hypothesis is that irritable bowel syndrome could be a problem of cerebral integration of visceral stimulation.

This study aims to characterize the Portuguese population of patients with moderate-to-severe UC receiving advanced therapies, by describing clinical and sociodemographic characteristics, and remission outcomes . The clinical, biochemical, endoscopic, and histological outcomes will also be described, as well as frequency of selected EIM, comorbidities and the uptake of preventive care measures and hospitalizations .

Background: Bacteria and other microorganisms that live in the intestines (the gut microbiome) play an important role in a person s health. The gut microbiome helps to regulate the immune system and control inflammation. Imbalances in the gut microbiome have been linked to illnesses such as inflammatory bowel disease (IBD). People diagnosed with IBD can have serious health problems. Researchers want to know more about how the gut microbiome affects the development and progression of IBD in children. In this natural history study, they will compare the gut microbiomes of healthy children with those who have IBD. Objective: To collect stool and samples of intestine tissue from children with and without IBD undergoing colonoscopy. Eligibility: People under 21 years old who are having a colonoscopy at the Inova Health System or Pediatric Specialists of Virginia. Design: Participants will fill out a questionnaire. They will answer questions about their history. Topics may include how they were fed as infants; how they were born; and how often they took antibiotics. Stool and tissue samples from the intestines will be taken during the participants colonoscopy. They may also give samples of blood and urine. Participants may be asked to provide additional stool, blood, and urine samples. They may do this up to 3 times per year. These samples may be collected at the clinic; they may also be collected at home and mailed to the researchers. If they have more colonoscopies, participants may be asked for more tissue samples. Participants will be enrolled for up to 10 years. ...

This study is being done to assess the clinical course and treatment options for Crohn's Disease (CD) and ulcerative colitis (UC) in the populations of Eastern Europe, Middle East, and North Africa.

To collect and store blood and biopsy samples obtained from CD or UC patients exposed to adalimumab and diagnosed with Hepatosplenic T-cell Lymphoma (HSTCL), for the purpose of identifying potential biomarkers and genetic mutations in patients who have developed HSTCL.

The purpose of this study is to develop a predictive model that will allow optimized dosing of infliximab for individual patients

The aim of the present study was to describe the incidence and prevalence of IBD in non Jewish Israel population

Provide pre-approval single patient Expanded Access (Compassionate Use) of Etrasimod for patients.

An accurate assessment of disease activity is crucial for the treatment of patients with ulcerative colitis (UC). Recent studies have reported that the Simple Clinical Colitis Activity Index (SCCAI) correlates well with Mayo score. A recent report demonstrated that SCCAI has a significant correlation with the degree of health-related quality of life in UC patients. It is also reported that the self-administered SCCAI through the web-based input tool at home is highly correlated with the SCCAI assessed by physician. The aim of this study was to investigate the relationship between self-administered web-based SCCAI and the health-related quality of life of UC patients.
