Inflammatory Bowel Diseases (IBD) go through two phases: flare and remission. Prediction of flares and identification of patients in remission but at high risk of flare are a major issue when taking care of IBD patients. Considering close interactions between sleep, immunity and intestinal inflammation, sleep disorders could be a predictor of flares. The purpose of this study is to demonstrate that sleep efficacy decreases before IBD flare. Patients in remission will be assessed for IBD symptoms (activity scores, biological factors) and sleep disorders (actigraphy, DREEM®, questionnaires) during one year.
Crohn's disease (CD) is a chronic transmural inflammatory bowel disease. Prolonged episodes of inflammation can lead to intestinal fibrosis, leading to intestinal stenosis and obstruction. Inflammatory stenosis can be alleviated through anti-inflammatory treatment, while fibrotic stenosis requires endoscopic dilation or surgical treatment. Early detection of the presence and severity of intestinal fibrosis in CD is the key to treatment strategies. Currently, there are certain limitations in the non-invasive evaluation methods for intestinal fibrosis, and it is urgent to develop a new imaging method to achieve non-invasive diagnosis of the degree of fibrosis. Fibroblast activation protein (FAP) is a marker of intestinal fibrosis in CD. Based on the principle that fibroblast activation protein inhibitor (FAPI) can specifically bind to FAP, FAPI radioactive tracers can achieve targeted tracing and quantification of FAP in vivo. Therefore, 18F-FAPI positron emission tomography (PET) imaging technology has a good application prospect in the noninvasive diagnosis and evaluation of CD intestinal fibrosis. Based on the successful testing of 18F-FAPI PET imaging in the early stage of the project team to evaluate the nature of CD intestinal stenosis, this project intends to take patients with CD intestinal stenosis as the research object, and use postoperative histopathological analysis as a reference index to evaluate the role of 18F-FAPI combined with 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose(18F-FDG) PET imaging in the qualitative diagnosis of CD intestinal wall fibrosis, as well as the differential diagnosis ability of inflammatory and fibrous stenosis in CD patients, and establish a diagnostic model and evaluation system. Achieving a noninvasive, stable, and objective diagnosis and evaluation of the degree of intestinal fibrosis in CD patients at the molecular level will provide imaging evidence for treatment decision-making, progress, and prognosis of CD patients, and also play an important support role in the development of anti fibrosis drugs, selection of suitable patients, and efficacy evaluation.
Patients with Crohn's disease (CD) could develop complications such as stricture, intestinal fistula and abdominal abscess. Some CD patients had poor response to medical therapy. The efficacy of exclusive enteral nutrition (EEN) to these adult active CD patients is still unclear. The investigators aim to study the efficacy of EEN in induction of remission in adult active CD patients with complications or poor response to drugs.
Crohn's disease (CD) is a chronic non-specific inflammatory disease of the intestine. Infliximab (IFX) is a kind of one of the anti-tumor necrosis factor agents (anti-TNF) and is the main clinical treatment drug for Crohn's disease, but approximately 30-50% of patients develop a secondary non-response to respond within one year. The main cause of secondary non-response failure is the formation of anti-IFX anti-drug antibodies (ADA). The human leukocyte antigen (HLA) gene is a complex allele that has been associated with susceptibility to a variety of diseases. Studies have shown that HLADQA1*05 allele carriage significantly increases the immunogenicity of anti-tumor necrosis factor agents (anti-TNF) and the risk of ADA formation, resulting in a significant reduction in the efficacy of IFX. Our previous retrospective study found an increased risk of ADA, IFX failure to respond and discontinuation in patients with HLADQA1*05 variants, and that IFX in combination with immunosuppression improved clinical outcomes in wild-type genotype patients, whereas combination therapy in patients with variant genotype did not optimize clinical outcomes significantly. Therefore, we believe that the impact of HLADQA1*05 on the efficacy of IFX in the Chinese population is unclear, and the combination of immunosuppressants in patients with variant HLADQA1*05 genotype remains to be validated due to insufficient sample size. We hypothesized that HLADQA1*05 wild-type CD patients would have better clinical remission when treated with IFX than HLADQA1*05 variant patients and that the combination of immunosuppressants would improve the outcome in wild-type patients but not in variant patients. By advancing this project, we hope to provide high quality evidence on the clinical use of IFX in Crohn's disease in the Chinese population and help physicians to be more selective in the use of IFX alone or in combination with azathioprine, or to switch treatment in a timely manner.
The goal of this clinical trial is to test the ATH-063 drug (single and multiple doses) in Healthy Subjects. The clinical trial aims to evaluate the below. 1. Safety of the drug 2. Tolerability of the drug 3. Pharmacokinetics (PK) (how the human body affects the drug) 4. Pharmacodynamics (PD) (how the drug affects the human body) This will be a single center, Phase 1, First-In-Human, Randomized, Double-Blind (neither the subjects nor the experimenters know which subjects are in the test and control groups), Placebo (a look-alike substance that contains no active drug) - Controlled Study.
Crohn disease is an inflammatory bowel disease. A surgical procedure is required in about 80% of cases. Surgery doesn't cure from Crohn's disease but the type of surgery remains important as there are several intraoperative risk factors for recurrence. Among these factors the microscopic inflammation at the resection margins. This is a crucial point, if the resection is too large there is a risk of short bowel syndrome, if the resection is too short (microscopic inflammation at resection site), there is a higher risk of postoperative recurrence (75% vs 46% at 18 months). Surgeons have to do a limited resection (2cm from macroscopic crohn disease). However this macroscopic non inflammatory resection margin can be microscopically inflammatory (up to 80%). Thus it is useful to evaluate if there is a microscopic inflammation at the resection margin. Moreover there is an increase interest for the role of the mesentery for recurrence but its role remains unclear. It is of interest to clarify the border between the inflammatory and non-inflammatory mesentery. Cellvizio is a confocal laser endomicroscopy providing the possibility of obtaining in vivo high-magnification images of the gut epithelium. This allows real-time examination of the gastrointestinal mucosa at the cellular and subcellular level. Cellvizio has never been used during surgery for Crohn disease. The aim of this study is to evaluate the intraoperative use of Cellvizio (using the CelioFlex microsonde) with an intravenous injection of fluorescein to determine the best ileal resection margins in Crohn disease.
The purpose of this study is to learn about the safety of the safety of the study medicine called infliximab for the possible treatment of rheumatoid arthritis (RA), ulcerative colitis (UC, Crohn's disease, or psoriasis. RA is a kind of joint disease that causes pain and swelling. UC causes inflammation and sores (also called ulcers), in the lining of the rectum and colon. Chron's disease is a disease that lasts for a long time and causes severe irritation in your digestive tract. Psoriasis is a skin disease that gives you a dry, scaly rash. The study includes patient's data from the database who: - Have at least 90 days of look-back period - Have any of these diseases (RA, UC, Crohn's disease, or Psoriasis) in the 90-day look back period - Are 15 years of age or older at the time of first dosing All the patient's data included in this study would have received infliximab as intravenous (into veins) injection.
The purpose of this study is to evaluate the effectiveness of guselkumab treatment compared with placebo (an inactive substance with no medicine) in preventing recurrence of Crohn's disease in participants after surgery.
Crohn's disease (CD) is a condition that causes inflammation (swelling, redness) of the lining and wall of the small intestine, large intestine, or both. CD may be associated with abdominal cramps/pain, diarrhea, blood in the stool, weight loss, or delayed growth in children. While the exact cause of CD is not certain it is thought that the immune system located in the intestine reacts abnormally to the large number of bacteria contained there. The investigators think that diet, exposure to antibiotics early in life, and having a family history of CD puts people at increased risk for developing CD. In order to decrease the inflammation doctors use what is called biologic therapy with anti-TNF molecules that can be given through an intravenous or shots. TNF is a chemical made by white blood cells that is involved in inflammation. When this type of treatment is given early after diagnosis it is more effective than when it is given later. The investigators have learned that it is important to give the optimum (ideal) amount of this medicine guided by certain blood tests. The investigators also know that not everyone responds to this therapy but do not understand the reasons for this variability between people. The CAMEO study has been started to help understand what factors are important in determining whether a child with CD completely heals the inflammation after anti-TNF therapy. The investigators will do that by measuring certain markers of inflammation in the blood and stool and by looking at a person's genes (DNA) and how inflammation is controlled in the intestine. These inflammation tests will be done before, during, and after one year of anti-TNF therapy. The investigators will determine how much healing has taken place by comparing the results of the colonoscopy and a special type of MRI that are both done before anti-TNF and then again one year later. The goal in treating CD is to heal both the lining and the wall of the intestine. Children ages 6-17 years who are thought to have CD and are about to undergo their diagnostic colonoscopy are eligible to be enrolled. If they are found to indeed have CD and start an anti-TNF medicine within 6 months they can continue in the study. There are no increased risks of participating in this study beyond those normally associated with having CD and its treatment. By better understanding why the bowel does or does not heal, doctors will be better able to provide personalized care.
