Active clinical trials for "Colitis"

This study is being done to: To attempt to increase the detection of precancerous colon tissue in patients with chronic ulcerative colitis and primary sclerosing cholangitis; To determine if an investigational scope that can look at the lining of the colon in different ways will help the doctor identify abnormal tissue in patients with chronic ulcerative colitis and concurrent primary sclerosing cholangitis; and To determine if this investigational scope can accurately detect precancerous or cancerous tissue in patients with chronic ulcerative colitis that are known to have had cancerous or precancerous tissue in the past.

Although Crohn's disease and ulcerative colitis are the main subtypes of inflammatory bowel disease, they differ substantially in disease behavior, prognosis, and treatment paradigm. However, making an accurate diagnosis of Crohn's disease versus ulcerative colitis and assessing disease activity beyond the level of mucosal inflammation remain challenging with contemporary modalities. The objective of the study is to determine the novel role of endoscopic ultrasound in A) differentiating Crohn's colitis versus ulcerative colitis and B) monitoring disease activity in these patients.

This is a prospective cohort study enrolling ulcerative colitis patients who initiate tofacitinib therapy. Investigators will collect clinical data, blood and stool samples prior to initiation of tofacitinib and, at minimum, monthly after the start of therapy. They will collect tissue from colonoscopies prior to initiation of therapy and within 6 months on therapy. Clinical characteristics and response to treatment will then be associated with genotype, blood immune profiles, stool microbiota, and cellular and molecular profiles of the biopsies to generate a treatment response model. Using predictors identified in our model, we will then attempt to validate the model and findings with the OCTAVE (Pfizer), SPARC (CCF), and RISK (CCF) data.

Monocentric, prospective observational study to assess bowel inflammation in children with chronic inflammatory bowel disease (IBD) using multispectral optoacoustic tomography (MSOT).

In this prospective, non-randomized cohort study, real-time intraoperative visualization using near-infrared-fluorescence by indocyanine green injection (ICG-NIRF) is performed at three time points during ileal pouch reconstruction. The intraoperative imaging findings are then analysed and correlated with the 30 day postoperative clinical outcome including occurrence of anastomotic leak of the pouch.

Background: The importance of cecal pathologies lie in the fact that being the first part of large intestine, any disease involving the cecum affects overall functioning of the large bowel. Primary cecal pathologies presenting as acute abdomen have not been described in any previous study in terms of presentation, management and outcome. Objectives: The objective of this study was to identify the reported causes of primary cecal pathologies presenting as acute abdomen and the various causes presenting in Indian setting, to discuss morbidity and mortality associated with cecal pathologies and to critically analyse the various management modalities employed in emergency setting.

The purpose of the study is to develop, evaluate, and optimize an interactive website (the SMART portal). The SMART portal will use IBD-specific and general assessments and interventions to reduce the burden of common barriers to treatment adherence and enhance self-management skills. This study aims to build and revise the SMART portal according to feedback and testing from participants.

The purpose of the study is to assess among others environmental and hygiene-related risk factors for microscopic colitis (MC), a common diarrheal disease.

For both induction of remission and in maintenance of remission, different doses and treatment durations are used in practice. The aim of this study is to assess how mesalazine is used in clinical practice, at which doses and for how long and how these differences impact the patient disease state and work productivity.

This phase is to register all subjects in Monroe County, New York with Inflammatory Bowel Disease (IBD) not already included to update the database for years 1990-2003. This will give us a truly population based study which will add to our knowledge of IBD epidemiology, allowing us to compare our rates with the rest of the world. We will be able to provide accurate incidence data from 1980 to 2000, and point prevalence from 12/31/2000. It will have special significance because of the relatively stable Monroe County population prior to 2000 (population in 1970=711,917; population in 2000 = 735,343).
