Active clinical trials for "Intestinal Diseases"

Malnutrition and growth retardation are major extraintestinal presentations of inflammatory bowel disease (IBD) in childhood and are especially prevalent among those with Crohn's disease. We aimed to evaluate nutritional status of children with IBD at the time of diagnosis.

The main aim of this study is to check the disease activity in people with moderate to severe ulcerative colitis and Crohn's disease. Participants will complete questionnaires about their disease and quality of life on Day 1 clinic visit. They will do this during a standard scheduled appointment with their doctor. Some of this study will also involve collecting information about participants from their medical records.

This study will examine the existence of genetic regions that are believed to bring about a risk for inflammatory bowel disease (IBD), with its subtypes of Crohn's disease and ulcerative colitis. It will identify the locations of chromosomes responsible for hereditary IBD through linkage analysis, a technique in genetic research in which the occurrence of a disorder in a family is evaluated alongside a known genetic disorder. The project will also do fine mapping of genes and examine possible genes associated with IBD. IBD is a chronic and often disabling disorder of the gastrointestinal tract, affecting about 500,000 Americans. Both Crohn's disease and ulcerative colitis share many characteristics, such as abdominal pain, bloody diarrhea, fever, fatigue, and malnutrition. But the main factors that distinguish these subtypes depend on the location and depth of inflammation. Tests and analyses can generally pinpoint some of the differences between the two, but sometimes there are major overlaps in characteristics, and the diagnosis is known as indeterminate IBD. The exact cause of IBD is not known, but genetic and environmental factors are known to contribute to risk for the disease. The single most important environmental risk factor has been smoking exposure at the time the diagnosis is made. Also, several genetic risk factors are ethnicity, family history, and polymorphisms-abilities to take on different forms-in the NOD2 gene. Patients who have a diagnosis of IBD and their family members 5 years of age and older who have or do not have that diagnosis may be eligible for this study. Participants will be asked to complete a questionnaire on their health, ethnic background, religion, habits, family medical history, and medications. Information will also be sought on the diagnosis, course, complications, and treatment of IBD, as well as risk factors. In addition, there will be collection of blood to be used for DNA preparation, storage of lymphocytes, and information on immunology.

The purpose of this study is collection and analysis of information pertaining to pregnancy outcomes in women exposed to infliximab during pregnancy, relative to the background risk in similar but non-biologic exposed patients; and information pertaining to health status, during the first year following delivery, of infants born to women following prenatal exposure to infliximab and their unexposed counterparts.

Numerous epidemiological studies have investigated the association between Helicobacter pylori (H. pylori) infection and inflammatory bowel disease (IBD) with various conflicting results. The main objective of this study is to further explore the possible association between H. pylori infection and IBD and its impact on disease course. The investigators sought to conduct a prospective observational study and enroll a total of 182 IBD patients who were screened for H. pylori infection. All the participants will be clinically evaluated at the initial visit and bimonthly for 3 months. Several factors will be explored such are diet, physical activity, life style and considering specific environmental exposures that impact the development of disease or its relapse.

Despite its known prevalence in IBD, a recent study conducted with Prof. Cacoub (unpublished) on the national health insurance database showed that iron deficiency was an under-diagnosed and under-treated co-morbidity. In chronic diseases including IBD, Transferrin Saturation Factor is only performed in approximately 10% of cases, whereas it is recommended in inflammatory situations including IBD patients (HAS 2011). The objective of this study is therefore to obtain updated French data on the prevalence of iron deficiency in patients with IBD by applying the recommendations of ECCO and French Health High Authority (determination of ferritinemia and Transferrin Saturation Factor)

Over the last few years, dysbiosis has emerged as a possible trigger of gut inflammation in inflammatory bowel disease (IBD) and a promising therapeutic target. The complex diversity of microbiota was initially highlighted by the powerful new tools in genetics, including next-generation sequencing (NGS). NGS permitted to decipher the composition of bacterial intestinal communities, but also that of the gut virome. Since then, the evidence of a dynamic instability of the enteric virome in IBD has grown considerably. IBD patients present an expansion of bacteriophages (Caudovirales) associated with decreased bacterial diversity. Moreover, gut virome richness seems to differ between Crohn's disease (CD) and ulcerative colitis (UC) patients. These insights open the gate of new diagnostic, predictive, and therapeutic approaches. However, little is known about pediatric IBD gut virome in terms of variability and evolution under the influence of different treatments (exclusive enteral nutrition, immunosuppressive therapy and biologics). The aim of this study is to evaluate the gut family viral diversity and relative abundance of eukaryotes and prokaryotes in paediatric IBD patients

The main objective was to demonstrate the existence and importance of hypercoagulability in patients with IBD, by determining the prevalence of changes in coagulation parameters and evaluating the impact of these changes on the occurrence of thromboembolic events.

The purpose of this research study is to understand the relationship between inflammatory bowel disease (IBD) and Glycogen storage disease (GSD)type Ia. GSD type Ib has been established to have an association with IBD with clinical and histologic features that mirror those of Crohn disease. Development of the disease seems to be related to the defect of neutrophil function in individuals with GSD type Ib and subsequent colonic inflammation. In the last decade, it has become a standard for patients with GSD type Ib and gastrointestinal symptoms to be evaluated for IBD. Patients with GSD type Ia were not recognized to have similar gastrointestinal symptoms until recently. The prevalence of IBD is greater in patients with GSD type Ia versus the general population.

The purpose of this study is to investigate the vaccination status, knowledge about vaccination, and attitude to vaccination of the Korean patients with inflammatory bowel diseases
