Active clinical trials for "Crohn Disease"

The purpose of this Registry study is to evaluate the long-term safety and effectiveness of adalimumab in CD subjects who are treated as recommended in the product label.

Measurement of the quality of life (QoL) of children and adolescents with inflammatory bowel diseases (IBD) has had little attention, despite the importance of understanding key factors affecting QoL, especially for measuring the effects of clinical trials to improve IBD outcomes. The main purpose of this pilot study is to examine the impact of clinical severity and treatment social factors on the quality of life (QoL) of a diverse population of children and adolescents with inflammatory bowel disease (IBD). Secondary purposes include determining the effects of sociodemographic factors on QoL and exploring the concordance of views of parents and children of QoL. The study aims are to 1) determine the associations of of clinical characteristics (condition type, activity/severity, and treatment) with specific components of general health-related quality of life and IBD-specific QoL; 2) describe the effects of sociodemographic characteristics (SES, age, and gender) on these measures; and 3) compare the views of different observers (parent and child with IBD) of the child's QoL. The study will apply both general and condition-specific QoL measures among a random sample of 250 children and adolescents with IBD, ages 5-18 years, in six clinical sites. We will obtain measures of QoL from both the child and a parent in each case. The study will obtain additional data regarding the subjects' clinical condition (condition type, severity/activity, treatment [including surgery], age of onset) and socioeconomic status (household structure and income). Main analyses will compare general and specific measures of QoL and examine the influence of clinical and sociodemographic variables on QoL, through multivariate regression techniques. We will also examine the differences in child and parent assessments of QoL. The information from this study will provide a stronger base for future studies of treatment and natural history of IBD. It will help to clarify the life domains that are affected by IBD and will inform interventions to improve QoL for children with IBD.

Six sites of the Pediatric Inflammatory Bowel Disease Consortium (plus 2 additional sites) will participate in this study. The participating sites will be that of the Principal Investigator (PI), Emory University School of Medicine, Atlanta, GA (Benjamin D. Gold, MD); Texas Children's Hospital / Baylor College of Medicine (George Ferry, MD and Tony Olive, MD); Children's Hospital of Philadelphia, Philadelphia, PA (Bob Baldassano, MD); University of Chicago Children's Hospital, Chicago, IL (Barbara Kirschner, MD); University of California, San Francisco (Mel Heyman, MD); Mass General Hospital / Harvard University (Harland Winter, MD); V.A. Stanford University School of Medicine, Stanford, CA (David Relman, MD); Children's Center For Digestive Healthcare, Atlanta, GA (Stanley Cohen, MD); and Centers for Disease Control and Prevention, Atlanta, GA (Drs. Jeannette Guarner, Siobhan O'Connor and Thomas Shinnick) The duration of study is 2 yrs. Objectives: Improve the methods to collect biopsies from the colon and ileum, tissue storage techniques and best methods to detect specific infections in children with Crohn's disease; Determine if there are specific infectious agents that are more common in children with Crohn's disease, and; Determine if there are types of children with Crohn's disease (e.g., children living in Boston, African American children) who may be more at risk for getting the infections. The study design involves children ages 6 months through 17 11/12 years of age who are undergoing a clinically-indicated colonoscopy. Subjects will be grouped into cases and controls. Any child ages 6 mos through 17 11/12 years of age, undergoing a clinically-indicated colonoscopy as determined by the treating physician, is eligible for enrollment. About 500 patients will be enrolled in this study. Cases will consist of those children within the defined age group, who are undergoing diagnostic colonoscopy and have the definitive diagnosis of Crohn's disease. Children who have the diagnosis of indeterminate colitis or ulcerative colitis for the purpose of this R03, will be excluded as cases and from initial analysis, but will have tissue specimens banked for subsequent evaluation for infectious agents. Controls will consists of children within the defined age group, undergoing clinically indicated colonoscopy and who are not diagnosed with Crohn's disease, ulcerative colitis or indeterminate colitis (e.g., juvenile polyps, irritable bowel syndrome or functional bowel disease). Stool specimen (5ml/1 tsp) will be collected to test for different types of bacteria A questionnaire will be administered to each research volunteer. Each subject's medical information (i.e. diagnosis, disease stage, and laboratory results) will be stored electronically in a separate access-based database. A unique identifier will be assigned to each patient entered into the study and will also be used for blinding of the specimens analyzed by the pathologist and by molecular assays for infectious agents. Colonoscopy will be performed by the treating pediatric gastroenterologist and biopsies obtained in the usual standard of care. Clinical biopsies from the rectum, left, right, transverse colon and cecum will be placed in formalin containing vials as per standard of care for the clinical pathologist and diagnostic evaluation.

Citrulline is an amino acid produced in the intestine and in the liver, but the liver does not contribute significantly to circulating citrulline concentrations. The intestine is thus the only organ that normally releases significant amounts of citrulline into the blood. The investigators have designed a study looking at the value of measuring plasma citrulline concentration in patients with Crohn's disease and short bowel or normal intestinal length. Measuring the plasma citrulline concentration in short bowel patients may help to distinguish between patients who need permanent parenteral feeding from patients with just transient intestinal dysfunction. It may also help the investigators in understanding the small bowel intestinal length remaining and the absorptive integrity. In patients with normal intestinal length and Crohn's disease, it may be a reliable marker of small bowel damage and could be applied to establish therapeutic improvements. It has been demonstrated to strongly correlate (inversely) with severity on intestinal biopsies. The investigators hypothesise that the plasma citrulline concentration is a marker for small bowel absorptive integrity and an appropriate surrogate for functional length of the small intestine. Controlled data do not yet exist to establish the place of plasma citrulline in the assessment of small bowel function in man.

Inflammatory bowel disease (IBD) patients under the age of 50 can have a greater risk than the general population above age 50. IBD patient are commonly treated with immunosuppression that increases the risk for Herpes Zoster. A new HZ vaccine is available that could decrease the risk of HZ in IBD patients.

Inflammatory bowel diseases (IBD) is a chronic inflammatory condition of the gastrointestinal tract that significantly affects quality of life of patients. Several studies have reported that the loss of work productivity is significantly higher than that of the general population due to disease-related symptoms and various factors in patients with inflammatory bowel disease in Western countries, but there is few data in Korea. Therefore, this study is to assess the effect of disease on sick leave, work disability and health related quality of life in Korean patients with inflammatory bowel disease by using validated questionnaires.

The primary objective of this study is to evaluate candidate predictors of persistence on adalimumab (Imraldi®) participants diagnosed with immune-mediated inflammatory disease in Europe (EU). The secondary objectives of this study are to describe participant clinical characteristics at baseline, utilization of Imraldi® over time, biologic drug effectiveness over time, participant satisfaction with biologic administration, routine laboratory values and clinical evaluation measurements over time, use of relevant concomitant medication use over time, immunogenicity of biosimilars and to summarize safety events.

This is an interventional randomized ope-label two-arm trial on the peri-operative use of immunonutrition in Crohn's Disease (CD) patients undergoing colorectal elective surgery.The aim of the trial is to assess the effectiveness of immunonutrition therapy in decreasing the rate of post-operative infective complications and 6 months endoscopic disease recurrence.

Ano-perineal lesions are the first signs of Crohn's disease in 1/3 to 1/2 of cases. They are most often associated with a poor prognosis of the disease and their management is complex and difficult because of the dilapidated and recurrent nature of lesions with significant repercussions on continence and quality of life. The treatment of these lesions is most often medical and surgical, consisting of drainage of the suppurative lesions and/or the use of biotherapy +/- combined with an immunosuppressant.

The M2iSH laboratory showed with two previous clinical trials that Crohn's Disease (CD) macrophages present i) a defect to control Adherent-Invasive Escherichia coli (AIEC) infection related to polymorphisms associated with CD; ii) a CD - specific cytokine secretion profile after an AIEC infection and intestinal inflammation dependent; iii) a modification of the response of CD macrophages at a basal state and after the AIEC infection. These results consolidate the hypothesis of a defect specific to CD macrophages. That's why, the primary purpose of this study is to realize a proteomic analysis of macrophages of CD patients infected or not with AIEC and to compare them to Ulcerative Colitis (UC) patients and healthy volunteers.
