Filter by:This study will evaluate pharmacokinetics, pharmacodynamics and safety of etrolizumab in pediatric patients of 4 to <18 years of age with moderate to severe ulcerative colitis (UC) or with moderate to severe Crohn's disease (CD).
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
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.
Ulcerative colitis (UC) belongs to the group of inflammatory bowel disease (IBD) and is characterized by a chronic relapsing disease course. As uncontrolled intestinal inflammation can lead to severe disease complications, treatment of UC has evolved from sole treatment of symptoms up to histological remission which is marked by the absence of histological inflammation. To correctly assess and quantify the degree of histological inflammation in IBD patients remains difficult. Digital holographic microscopy (DHM) is a new imaging technique belonging to quantitative phase contrast imaging. It is based on the detection of optical path-length delays in a stain-free manner, thereby providing a refractive index which directly correlates to tissue density. This study aims to evaluate the role of DHM for quantifying the degree of histological inflammation in endoscopically acquired biopsies of UC patients in a prospective clinical trial. From 28 UC patients, the investigators will obtain endoscopically acquired colonic biopsies. The investigators will assess the degree of inflammation in these biopsies using DHM and in addition to this an experienced histopathologist will determine the degree of inflammation in these biopsies using a histological scoring system (Nancy-Score = goldstandard). Finally, the investigators will directly correlate the results from DHM analysis to the histological analysis using the Nancy-Score.
Alterations in the intestinal microbiota have been associated to disease pathogenesis in ulcerative colitis. Refractory disease to standard medical therapy as corticosteroids often leads to an unfavourable course in patients suffering from this disorder. This study proposal aims at investigating changes in the intestinal microbiota that can predict a therapy refractory course of ulcerative colitis (UC) and may be used to identify high risk patients in an early phase of their disease.
The primary objectives of this study are to evaluate the potential for preoperative pharmacogenomics (PGx) testing to positively influence postoperative opioid use through visual analog scale (VAS) guided administration of narcotic equivalent and lower pain scores as measured by OBAS in patients undergoing major abdominal surgery.
The purpose of this observational study is to assess the safety and effectiveness of biosimilar Infliximab in patients with inflammatory bowel disease (IBD) in Saudi Arabia where no visits or intervention(s) additional to the daily practice will be performed.
Ulcerative colitis (UC) is an entity of complex etiology where environmental, genetic and intestinal microflora-related factors trigger and perpetuate a chronic inflammation of the gastrointestinal tract. It is suspected that an alteration in primary intestinal microbial colonization (dysbiosis) could trigger, or at least contribute to, said oversized immune response. The hypothesis is that the administration of a series of fibers, could improve the bacterial diversity and repair the dysbiosis that has been seen in patients affected by ulcerative colitis, improving the clinical evolution of it. The primary objective of the present study is to know the impact on the microbiota of patients with UC in remission derived from the administration of dietary fibers. The RETOS study is a pilot project in which a population of patients with UC is tested for the effect on the composition of the microbiota that would have the administration of various combinations of fibers, in addition to the tolerability and acceptance by the patient. The clinical applicability derived from this intervention would be to improve the diversity of intestinal flora of patients with ulcerative colitis.
Ulcerative colitis (UC) is a chronic inflammatory disorder of the gastrointestinal tract of unknown etiology. UC is characterized by recurring episodes of inflammation limited to mucosal and submucosal layers of the colon. The object of the present study was to determine the prevalence of intestinal protozoa and helminthes in UC patients, and the role of this changes in aetiopathogenesis of diseases. Patients will be examined before and after therapy. Parasites and protozoa prevalence and intensity will be detected by triple coproscopy.Microbiological study will be conducted before therapy for detection pathogenic bacteria only from UC patients infected with B. hominis . If intestinal pathogenic bacteria are found, participants will be excluded from further investigation.
Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) characterized by chronic inflammation limited to colonic mucosa. Its pathogenesis is not still clear, even if a multifactorial aetiology has been advocated. The aim of this study is to evaluate the long-term efficacy of two different doses of VSL#3® added on standard therapy (5-ASA) in maintaining remission in an adult population of patients with UC, compared with the standard therapy (5-ASA) plus placebo. The investigators hypothesized that adding VSL#3® to mesalamine would lead to higher remission rate at long-term evaluation.
