Ulcerative colitis is a common inflammatory disease of the colon characterized by inflammation and ulceration of the large bowel and rectum. The condition impairs the ability of the large bowel to absorb water which results in diarrhea, the main symptom of the condition.
Ulcerative colitis is a relapsing and remitting condition, meaning symptoms can die down for long periods but then flare-up from time to time. These flare-ups can be sudden and severe. During a period of relapse, symptoms may include bloody diarrhea, abdominal pain and a sudden urge to defecate. Other symptoms include wind, loss of appetite, weight loss, fever and fatigue.
Currently, there is no cure for the condition apart from surgery. However, certain treatments such as corticosteroids or immunosuppressants may be used to ease symptoms by reducing inflammation. Surgery for severe ulcerative colitis that does not respond to treatment involves completely removing the large bowel and re-routing the small bowel so that waste can still be expelled. This procedure is called a colectomy.
In the UK, the incidence of ulcerative colitis is around 1 in 500 and the condition is equally common among males and females. Symptoms can develop at any age, but onset usually occurs between 15 and 30 years of age.
Around 500,000 people in the UK live with Inflammatory Bowel Disease (IBD), a life-long, chronic condition characterized by sporadic bouts of gut inflammation causing debilitating symptoms.
Ulcerative colitis is an inflammatory bowel disease (IBD) that causes inflammation and ulcers (sores) in the digestive tract. Ulcerative colitis affects the innermost lining of the colon and rectum.
An international team led by the Case Western Reserve University School of Medicine has discovered novel properties of the protein Gasdermin B that promotes repair of cells lining the gastrointestinal tract in people with chronic inflammatory disorders like Crohn's disease and ulcerative colitis.
Microplastics -; tiny pieces of plastic less than 5 mm in length –– are everywhere, from bottled water to food to air. According to recent estimates, people consume tens of thousands of these particles each year, with unknown health consequences.
A grant from the Novo Nordisk Foundation of up to 300 million euro now enables the establishment of a major international research center focused on stem cell medicine.
The cliché "you are what you eat" has been used for hundreds of years to illustrate the link between diet and health. Now, an international team of researchers has found the molecular proof of this concept, demonstrating how diet ultimately affects immunity through the gut microbiome.
Scientists from the Francis Crick Institute unraveled a basic role of glial cells in the nervous system of the gut in retaining a healthy intestine.
A new study reported in Nature Communications shows that a consortium of bacteria, developed to complement lacking or poorly represented functions in the imbalanced microbiome of inflammatory bowel disease (IBD) patients, inhibited and treated chronic immune-mediated colitis in humanized mouse models.
More Canadians suffer from inflammatory bowel disease (IBD) than anywhere else in the world, yet current treatments often have debilitating side effects and are not always effective.
For all their importance as a breakthrough treatment, the cancer immunotherapies known as checkpoint inhibitors still only benefit a small minority of patients, perhaps 15 percent across different types of cancer. Moreover, doctors cannot accurately predict which of their patients will respond.
Scientists from the Lerner Research Institute at Cleveland Clinic have designed an innovative, patient-derived model of ulcerative colitis that will help scale up studies into new therapies for chronic inflammatory bowel disease.
A potential preventive treatment for Crohn's disease, a form of inflammatory bowel disease, has been demonstrated in a mouse model and using immune-reactive T cells from patients with Crohn's disease.
A Rutgers study has discovered that vitamin D regulates calcium in a section of the intestine that previously was thought not to have played a key role.
Using sophisticated 3D genomic mapping and integrating with public data resulting from genome-wide association studies (GWAS), researchers at Children's Hospital of Philadelphia (CHOP) have found significant genetic correlations between inflammatory bowel disease (IBD) and stress and depression.
Severe ulcerative colitis - a form of inflammatory bowel disease (IBD) - has been linked to a newly-discovered strain of oral bacteria, a study led by UNSW Sydney has found.
The results obtained are encouraging and the researchers could make headway in a multifunctional cell therapy system to treat inflammatory bowel disease.
Scientists from King's College London have discovered an unexpected tissue reparative role for a rare immune cell type in the gut that could tip toward fibrosis or cancer if dysregulated.
Inflammatory bowel disease (IBD) is a group of intestinal disorders affecting an estimated six to eight million people worldwide.
Enzymes used by bacteria to break down mucus in the gut could provide a useful biomarker for intestinal diseases, according to new research published in Nature Communications.
In a new study, researchers have compared diseased colon with healthy tissue to better understand how inflammatory bowel disease (IBD) is linked to an increased risk of colorectal cancers, at a molecular level.
