This study will collect tissue specimens to be used for research on inflammatory bowel disease. The tissues will be used to explore why people get inflammatory bowel disease and to try to develop new treatments based on the study results. Tissue from patients with IBD will be compared with that from patients who do not have the disease
Patients who undergo bowel surgery for inflammatory bowel disease (IBD) or another bowel disorder may be eligible for this study. Patients with IBD must be at least 4 years of age; those with another disorder must be 18 years of age or older.
Participants undergo bowel surgery for their disease. Some of the intestinal tissue removed during the surgery that is not needed for medical care, such as for pathological examination, is provided to researchers for study under this protocol. In addition, patients with IBD provide a blood sample for genetic testing. Several genetic variations, or mutations, may increase the risk of developing IBD; blood samples from patients may help identify these variations.
Our ongoing natural history studies of the etiology and immune abnormalities of the group of diseases known collectively as the inflammatory bowel diseases require access to clinical samples of intestinal tissue as well as blood samples for genotyping. This protocol provides a mechanism for procurement of intestinal samples obtained at the time of medically-indicated surgical procedures from patients with IBD or some other non-IBD diagnosis (to act as a control group). In addition it allows for the procurement of blood for DNA preparation as more IBD susceptibility genes are discovered and we further our work on association of genetic polymorphisms/mutations with the phenotype and immune abnormalities observed in our IBD patients.

The aim of this study is to compare medical and surgery treatment in IBD patients and healthy controls, by assessing the endothelial and cardiac function and the inflammation status.
We evaluated the impact of variations in ATG16L1 and NOD2 and genes on serologic responses in patients with inflammatory bowel disease (IBD).
Inflammatory bowel diseases (IBDs) are a group of heterogeneous inflammatory conditions affecting the gastrointestinal tract. Although there is considerable evidence linking the gut microbiota to inte...
An association between inﬂammatory bowel diseases (IBD) and increased susceptibility to sexual dysfunction (SD) was reported in a number of studies.
Inflammatory bowel diseases (IBDs) are commonly diagnosed during the reproductive years. IBD first manifested during pregnancy (pregnancy-onset IBD [POIBD]) is still an undescribed entity. The aim of ...
Inflammatory bowel disease (IBD) mainly consists of Crohn's disease (CD) and ulcerative colitis (UC). About 10%-15% of patients with IBD cannot be firmly diagnosed with CD or UC; hence, they are initi...
A species of Faecalbacterium, previously classified in the FUSOBACTERIUM genus, that is a major constituent of the GUT MICROBIOTA in healthy humans. It has anti-inflammatory activity and reduced numbers of this species occur in patients with INFLAMMATORY BOWEL DISEASES such as CROHN DISEASE.
Chronic, non-specific inflammation of the GASTROINTESTINAL TRACT. Etiology may be genetic or environmental. This term includes CROHN DISEASE and ULCERATIVE COLITIS.
A drug that is used in the management of inflammatory bowel diseases. Its activity is generally considered to lie in its metabolic breakdown product, 5-aminosalicylic acid (see MESALAMINE) released in the colon. (From Martindale, The Extra Pharmacopoeia, 30th ed, p907)
Surgical creation of an external opening into the ILEUM for fecal diversion or drainage. This replacement for the RECTUM is usually created in patients with severe INFLAMMATORY BOWEL DISEASES. Loop (continent) or tube (incontinent) procedures are most often employed.
A gamma-emitting radionuclide imaging agent used in the evaluation of regional cerebral blood flow and in non-invasive dynamic biodistribution studies and myocardial imaging. It has also been used to label leukocytes in the investigation of inflammatory bowel diseases.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
