Filter by:The purpose of this study is to evaluate if the combination of oral budesonide and rectal hydrocortisone improves symptoms in patients with active ulcerative colitis. Also, we would like to determine if oral budesonide and rectal hydrocortisone has fewer and less severe side effects compared to standard steroids (prednisone).
Ulcerative colitis is an inflammatory bowel disease that afflicts up to one million people in the U.S. Symptoms include rectal urgency, bloody diarrhea, moderate to severe abdominal pain, fever, and fatigue. Melatonin is a hormone that is associated with sleep and other body functions that may be related to health. Melatonin is produced in the pineal gland and, in fact, it is produced in even greater amounts in the gut. Melatonin appears to be important in gastrointestinal tract physiology and health, and data from cell and animal experiments, and some studies in humans, suggest that supplemental melatonin may help ameliorate colitis. Given that current treatments for ulcerative colitis are not always effective, and often have serious side effects, there is considerable interest in finding alternative treatments for this disease. However, experimental data on the ability of melatonin to improve ulcerative colitis in humans are lacking. To address this, we plan to conduct a pilot clinical trial (60 adult male and female participants) that will obtain preliminary data about the effectiveness of melatonin supplementation as a treatment for ulcerative colitis in adult men and women with the disease.

Ulcerative colitis is a chronic inflammatory bowel disease caused by an imbalance between natural defence mechanisms in the intestinal mucosa and microbes in the intestinal lumen. We hypothesise that an improvement or even normalisation of this balance may be achieved by the use of vaccines and dietary oats. The combined use of oral typhoid vaccine and cholera/ETEC-vaccine is supposed to stimulate mucosal defence factors, while dietary oats modifies the microbial environment inside the intestinal lumen. Or study aim is to show if such treatment brings symptom relief to patients with ulcerative colitis.
The purpose of this study is to evaluate the efficacy of the addition of GMA apheresis to steroid conventional treatment for achieving and maintaining remission in Active steroid dependant Ulcerative Colitis patients
The primary purpose of this prospective, randomized multicenter center study is to evaluate and compare the outcomes of colorectal, coloanal and ileoanal anastomoses reinforced with a bioabsorbable staple line reinforcement material compared with standard non-reinforced colorectal, coloanal and ileoanal techniques with respect to the incidence of postoperative anastomotic leakage, anastomotic stricture and time to ileostomy closure, if applicable.
This is a confirmatory, multicentric, prospective, randomized, controlled, single-blind study in subjects with long standing ulcerative colitis in clinical remission with indication for surveillance colonoscopy. The patients are examined with the PENTAX EC-3870CIFK and EC-3870CILK confocal colonoscopes either by chromoscopy-guided endomicroscopy with targeted biopsies or by standard endoscopy with random and targeted biopsies. The aim is to investigate whether chromoscopy-guided endomicroscopy has a higher sensitivity than standard endoscopy with respect to detection of intraepithelial neoplasia (IN) and to compare the proportion of patients with at least 1 IN detected by chromoscopy-guided endomicroscopy versus standard endoscopy.
The metabolic response to ulcerative colitis, including increased proteolysis and lipolysis and changes in energy expenditure, plays a significant role in the resulting malnutrition from which these patients suffer. Tumor necrosis factor-alpha (TNF-alpha), a pro-inflammatory cytokine, has been found to be elevated in children with ulcerative colitis. TNF-alpha has been incriminated in the mechanism of weight loss in many different chronic diseases, and causes net protein and lipid catabolism. Anti-TNF-alpha antibody (infliximab) has been proven to be an effective therapy for ulcerative colitis. The purpose of this study is to determine changes in protein and lipid metabolism, as well as resting energy expenditure, before and after therapy with anti-TNF-alpha antibody (infliximab) in children with ulcerative colitis. Performing this study will better define the changes in nutrition status observed in these children following remission of active ulcerative colitis, and potentially lead to changes in medical and nutritional management of these children
There is increasing evidence that worsening of ulcerative colitis (UC) can be provoked by psychological stresses. When this protocol was devised, there had been no proper scientific studies to find out whether stress reduction can improve the course of UC. Hypnotherapy is a technique by which a practitioner induces a temporary trance-like state in patients: while they are in this state, the practitioner uses suggestion to induce relaxation as well as beneficial modification of the way in which the patient experiences the gut working. In previous studies in our lab, we have shown that a single 50 minute session of hypnosis can reduce special indicators of inflammation both in the blood-stream and in the lining of the lower bowel (rectum). Furthermore, in earlier work by others, hypnosis had been shown to be effective in the treatment of patients with irritable bowel syndrome, duodenal ulcer and indigestion unassociated with ulcers. Many patients with UC need to take the immunosuppressive drug, azathioprine, in addition to a 5ASA drug, to keep their disease under control. While azathioprine is usually effective in maintaining remission of UC, it does require regular drug checks and carries the risk of possible side-effects. We undertook a study of hypnotherapy to see whether it can prevent relapse (worsening) of UC in patients who normally need to take azathioprine to keep their UC inactive. To do this, we planned to ask 66 patients who agreed to participate in the trial to stop their azathioprine. They were then to be allocated to receive either gut-focussed hypnotherapy (44 patients) or, as a control, non-emotive educational sessions (22 patients) once a month for 3 months, with intervening self-hypnosis daily in the active arm. The numbers of patients in each group who developed relapse of their UC in a year were recorded. We diagnosed relapse from patients' diaries recording diarrhoea and bleeding, and by sigmoidoscopy. It was hoped that this clinical trial would identify a new drug-free way of reducing the chances of relapse in patients with UC.
Part 1 of this study is a 3-arm, randomized, active-controlled, parallel-group, multicenter, double-blind, double-dummy, 16-week study to compare the efficacy and safety of infliximab (IFX), as monotherapy or in combination with azathioprine (AZA) versus AZA monotherapy in adults with moderate to severe active ulcerative colitis (UC). Participants who qualify at the Baseline Visit will be eligible to be randomized to one of the three active treatment groups. Participants in the IFX/AZA combination therapy and IFX monotherapy cohorts will receive IFX infusions at Weeks 0, 2, and 6 and daily oral AZA/placebo, respectively; participants in the AZA cohort will receive daily oral AZA and placebo infusions at Weeks 0, 2, and 6. At Week 8, all participants will be evaluated for response. Participants responding to IFX treatment at Week 8, either as monotherapy or in combination with AZA, will receive one more IFX infusion at Week 14; non-responders to IFX therapy will receive placebo infusions at Weeks 8 and 10 and one additional IFX infusion at Week 14. Participants responding to AZA monotherapy at Week 8 will continue on AZA therapy and receive one placebo infusion at Week 14; nonresponders to AZA will be eligible to receive IFX at Weeks 8, 10, and 14. Part 2: Participants in remission on IFX monotherapy or IFX/AZA treatment at Week 16 will be randomized to either maintenance or intermittent open-label IFX treatment; randomization will be stratified based on oral AZA/placebo treatment in Part 1. Oral AZA/placebo treatment will continue to be double-blinded. All participants will continue to receive oral AZA/ placebo for the duration of the study. Participants randomized to maintenance IFX treatment will receive scheduled IFX infusions every 8 weeks beginning at Week 22 (Week 6 for direct entry). If participants lose response, or if treatment has to be discontinued because of an adverse event, these participants are considered treatment failures, and should be followed up for safety at the scheduled 6-month visits (Weeks 38, 62, and 94 [Weeks 22, 46, and 78 for direct entry]). These participants will receive standard of care per their personal physician. Participants randomized to intermittent IFX treatment will be evaluated every 8 weeks. Participants will receive IFX only upon relapse of disease. Treatment with IFX will be initiated at Weeks 0, 2, and 6 of the individual treatment cycle and will continue every 8 weeks until remission is regained. Throughout the study, individual treatment cycles will be repeated whenever a subject relapses. In addition, to facilitate enrollment into Part 2, participants who received treatment outside of Part 1 and who are in remission on IFX with or without AZA/6-mercaptopurine (6-MP) will be allowed to enter directly into Part 2. In the Czech Republic, direct entry into Part 2 of the study is not allowed. A higher than expected incidence of serious infusion reactions observed in the intermittent treatment arm of another study (Protocol P04563, NCT0358670) conducted in participants with moderate to severe psoriasis resulted in the termination of that study. Based on the similarities in study design between the intermittent treatment arm of P04563 and the intermittent treatment arm of Part 2 of this study, enrollment to Part 2 of this study was put on hold, for precautionary reasons. At the same time, all participants already enrolled in the intermittent treatment arm of Part 2 were asked to discontinue from the trial. In October 2009, a decision was made by the sponsor to terminate the whole study (Part 1 and 2). At that time, participants enrolled in Part 1 of the study were allowed to complete their treatment up to Week 16.
The aim of this double blind, placebo controlled, study is to evaluate activity consistent with efficacy provided by 14 days administration of GI270384X, and to provide preliminary pharmacokinetics and safety/tolerability of 14 days administration of GI270384X in patients with mild to moderate active ulcerative colitis (UC).
