Ulcerative Colitis

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.

What is Ulcerative Colitis?

Ulcerative colitis is a chronic condition that affects the large intestines, particularly the colon. It is classified as one of the two inflammatory bowel diseases along with Crohn’s disease.

Study identifies genetic risk for fatal blood clots in IBD patients

Blood clots are the biggest cause of death in patients with inflammatory bowel disease (IBD) ─ ulcerative colitis or Crohn's disease. In a retrospective study recently published in the journal Gastroenterology, Cedars-Sinai investigators found that a combination of rare and common genetic variants in some IBD patients significantly increased their risk of developing clot-causing thromboembolic diseases.

Researchers launch clinical trial to assess therapeutic drug monitoring for patients with inflammatory diseases

New research presented at ACR Convergence, the American College Rheumatology's annual meeting, showed that patients with rheumatic diseases whose infliximab treatment was individually assessed and adjusted with a new strategy called therapeutic drug monitoring did not achieve remission at higher rates compared to those who received standard care.

New IBD safety registry established to support the completion of post-marketing safety requirements

The Pediatric IBD Foundation, ImproveCareNow, and the Critical Path Institute (C-Path) are proud to announce a collaboration establishing the Children's Registry for the Advancement of Therapeutics (CREATE™).

Study suggests a role for the hypothalamus in genetic susceptibility to IBD

Using sophisticated 3D genomic mapping and integrating with public data resulting from genome-wide association studies, researchers at Children's Hospital of Philadelphia have found significant genetic correlations between inflammatory bowel disease and stress and depression.

Severe ulcerative colitis linked to a newly-discovered strain of oral bacteria

Bacteria from the mouth could hold clues to understanding – and potentially treating – severe ulcerative colitis, a painful bowel disease.

People with depression are more likely to develop Crohn's disease

A new study, published inGut, has found depression is more common among people with Crohn's disease or ulcerative colitis in the years before they are diagnosed with these bowel conditions.

Readers and tweeters shed light on vaccine trials and bias in health care

In the piece about the AstraZeneca vaccine trial subject who suffered severe spinal cord inflammation, that person was repeatedly referred to as a "patient" ("NIH 'Very Concerned' About Serious Side Effect in Coronavirus Vaccine Trial," Sept. 14).

Intestinal microbiota offers new prospects for treating celiac disease

Celiac disease is an immune disease of the intestine that affects more than 1% of the population. It is characterised by gluten intolerance that causes inflammation of the gut, abdominal pain and diarrhoea, and can lead to weight loss and deficiencies among patients.

Tryptophan found in turkeys can accelerate intestinal healing in people with celiac disease

People with celiac disease may find themselves more comfortable with extra Thanksgiving turkey dinners.An international team of researchers led by McMaster University has found that tryptophan, an amino acid present in high amounts in turkey, along with some probiotics, may help them heal and respond better to a gluten-free diet.

Researchers identify pathogen responsible for creeping migration of fat in Crohn's patients

In many patients with Crohn's disease, abdominal fat migrates to the wall of the inflamed small intestines. What prompts the fat tissue to "creep" through the abdomen and wrap around the intestines of many patients with this inflammatory bowel disease (IBD) has been an enduring mystery.

Study shows tofacitinib drug can repair permeability defects in the intestine

A team of researchers led by biomedical scientist Declan F. McCole at the University of California, Riverside, has found that the drug tofacitinib, also called Xeljanz and approved by the FDA to treat rheumatoid arthritis and ulcerative colitis, can repair permeability defects in the intestine.
