Filter by:The goal of the study is to evaluate strategies that target the microbiota for the treatment of Ulcerative Colitis , This study will involve a novel diet that the investigators developed , based on the hypothesis that UC involves dysbiosis , underutilzation of certain metabolic pathways and use of pathways that increase risk of inflammation . The investigators have postulated that manipulation of colonic bacterial metabolism with this diet will induce remission in UC without involving additional immune suppression.
A disturbance in the diversity of gut bacterial composition could be linked to several immune mediated diseases including inflammatory bowel diseases (IBD). IBD can be classified into Crohn's Disease (CD) and Ulcerative Colitis (UC). Both these diseases occur from abnormal immune reaction to resident gut bacteria.The process of fecal microbiota transplantation (FMT) where fecal bacteria from a healthy individual is transferred into a recipient, has recently received attention as an alternative therapy for individuals affected with these life-altering diseases. In this study, the investigators will perform fecal transplantation on the subjects meeting inclusion criteria, to determine the efficacy and safety of this therapy in subjects with IBD (CD and UC) who are not responding to first line therapy, and are in a flare.
To evaluate safety and efficacy of two adalimumab dosing regimens for induction and maintenance (standard and higher dosing) in achieving clinical remission in subjects with moderately to severely active ulcerative colitis.
The aim of this study is to a.) evaluate whether early serum infliximab levels are predictive of avoidance of colectomy, b) evaluate whether serum albumin levels correlate with serum infliximab levels, and c) evaluate whether serum tumor necrosis factor levels are inversely correlated with serum infliximab levels. In patients hospitalized for severe ulcerative colitis and treated with high-dose infliximab, we predict that early serum infliximab levels (24, 48, and 72 hour) will be positively associated with clinical response and avoidance of colectomy.
This study aims to evaluate the effect of vitamin D3 supplementation on disease activity and quality of life in IBD patients deficient in vitamin D, and also help determine the optimal dose of vitamin D3 for them. Hypothesis: Supplementation of vitamin D3 in IBD patients with hypovitaminosis D can improve their quality of life and decrease IBD activity.
This is an observational cohort study with two time points (baseline and after at least 6 months of treatment with a non-corticosteroid immunosuppressive agent for inflammatory bowel disease (IBD)). Approximately 40 participants, both male and female, 18 years of age and older will be recruited from the Pittsburgh IBD Cohort. Participants will have a histological diagnosis of IBD (Ulcerative Colitis (UC) or Crohn's Disease (CD)) and will be attending for colonoscopy prior to starting a non-corticosteroid immunosuppressive agent as part of standard medical care. Immediately following the colonoscopy, an anal exam will be performed for research purposes to include: 1. Perianal inspection 2. Anal canal HPV swab 3. Anal cytology 4. Digital anal examination 5. High resolution anoscopy (HRA) and biopsy of all lesions with visual criteria consistent with high-grade anal dysplasia 6. For female participants a self- or clinician-taken vaginal swab for HPV typing. These procedures will be repeated at routine colonoscopy following at least 6 months but within 12 months of non-corticosteroid immunosuppressive treatment.
