Filter by:The objectives were: (1) To demonstrate the efficacy of adalimumab in the long-term maintenance of clinical remission in participants with Crohn's disease; and (2) To delineate the long-term safety of adalimumab when administered to participants with Crohn's disease.
Wireless Capsule Endoscopy has been the most reliable diagnostic standard for small bowel Crohn's disease. Endoscopic healing is an important endpoint to measure response to treatment.
Using scintigraphic imaging including planar scintigraphy and SPECT, this study will evaluate the utility of two different ex vivo 99mTc-HMPAO labelled mononuclear cell populations in order to select the optimal methodology (using PBMC or purified lymphocyte subpopulations) for future drug intervention studies in Crohn's disease. Two parallel exploratory approaches will be investigated to enrich for lymphocyte populations expressing leukocyte trafficking inhibitors. In the first, whole blood will be fractionated on a ficoll gradient to purify a heterogeneous population of all the peripheral blood mononuclear cells (PBMC) for labelling. Secondly, further enrichment will be attempted using depletion of PBMC fractions of monocytes and B cells.
IBD is caused by an abnormal immune response to the gut bacteria in people who are genetically predisposed. There has been a huge increase in the number of people diagnosed with IBD since World War II, likely due to changes in our environment. It is possible that the abundance of vitamin D in the body may be one of those environmental factors that the investigators can control to make patients with IBD better. Vitamin D acts on cells of the immune system and causes many effects, including the production of a "natural antibiotic" called cathelicidin. The investigators know that when people are supplemented with vitamin D, levels of cathelicidin produced by these immune cells increase. By supplementing children with Crohn's disease with vitamin D, the investigators may be able to alter their immune system "naturally," making their disease better. A consensus of vitamin D experts believes that vitamin D levels need to reach a level of 40-70 ng/mL in the blood in order to have effects on the immune system. Raising vitamin D levels to this range is one of the goals in the current study.
Background: The marijuana plant Cannabis has been used for centuries in the medicinal treatment of many disorders and is still the subject of medical research and public debate. Cannabinoids have been purported to alleviate a variety of neurological conditions such as MS-related symptoms including spasticity, pain, tremor and bladder dysfunction. Other neurological conditions like chronic intractable pain, dystonic movement disorders and Tourette's Syndrome were all reported to be alleviated by cannabis use. Cannabis has been used to treat anorexia in AIDS and cancer patients. In gastroenterology cannabis has been used to treat symptoms and diseases including anorexia, emesis, abdominal pain, gastroenteritis, diarrhoea, intestinal inflammation and diabetic gastroparesis. Cannabinoids have also a profound anti inflammatory effect, mainly through the CB2 receptor. Cell mediated immunity may be impaired in chronic marijuana users. And a potent anti-inflammatory effect of cannabis was observed in rats . Studying the functional roles of the endocannabinoid system in immune modulation reveals that there are no major immune events which do not involve the endocannabinoid system. Cannabinoids shift the balance of pro-inflammatory cytokines and anti-inflammatory cytokines towards the T-helper cell type 2 profiles (Th2 phenotype), and suppress cell-mediated immunity whereas humoral immunity may be enhanced. They are therefore used for various inflammatory conditions including rheumatoid arthritis and asthma. In a mouse model of colitis cannabinoids were found to ameliorate inflammation and there are many anecdotal reports about the effect of cannabis in inflammatory bowel disease. However, there are no methodical reports of the effect of cannabis on inflammatory bowel disease. The aim of the proposed study is to examine in a double blind placebo controlled fashion the effect of smoking cannabis on disease activity in patients with IBD.
There are many anecdotal reports about improvement of Inflammatory bowel diseases (IBD) with cannabis smoking. The most effective anti inflammatory compound known today is cannabidiol. cannabidiol can be extracted from the cannabis plant, it has no central effect and is fat soluble so it can be given as drops in oil. Doses of up to 500mg did not cause any side effects. The aim of the proposed study is to examine in a double blind placebo controlled fashion the effect of cannabidiol on disease activity in patients with IBD.
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).
Assess if the implementation of a treatment algorithm will improve the management of Crohn's disease (CD) in comparison to usual care based gastroenterology practices.
The purpose of this study is to determine if increasing the dose and/or dosing frequency of certolizumab pegol (Cimzia) is effective in regaining and optimizing response in patients with moderate to severe Crohn's disease.
The aim of this study is to evaluate three diagnostic methods for assessing small bowel disease in patients with suspected or known Crohn's disease. All patients are examined with ileo-colonoscopy, capsule endoscopy, MRI and CT of the small bowel within 14 days. However, capsule endoscopy is not performed in patients with stenosis detected at ileo-colonoscopy, MRI and/or CT. All investigations are described in a similar pre-defined and standardized fashion and the radiologist and physician responsible for describing the findings at MRI, CT and capsule endoscopy are blinded to the findings at ileo-colonoscopy. The physician in charge of treatment receives a randomised result of either MRI, CT or capsule endoscopy. Thereafter patients are followed during 12 months to evaluate differences in clinical outcome depending on the randomized result. In combination with the diagnostic validity and inter-observer agreement of MRI, CT and capsule endoscopy we seek to establish the optimal diagnostic strategy in these two patient categories.
