New Inflammatory Bowel Disease Testing Protocol could Speed up Diagnosis

Serial home tests would reduce unnecessary colonoscopy testing. Patients with suspected inflammatory bowel disease (IBD) could benefit from better testing protocols that would reduce the need and lengthy wait for potentially unnecessary colonoscopies, a new study has found.

In a paper published in Frontline Gastroenterology, researchers from the Birmingham NIHR Biomedical Research Centre (BRC) at the University of Birmingham tested a new protocol to improve IBD diagnosis combining clinical history with multiple home stool tests.

In the two-year study involving 767 participants, patients were triaged and had repeated faecal calprotectin (FCP) tests and the research team found that the use of serial FCP tests were able to strongly predict possible IBD as well as Crohn’s Disease an...

Anti-inflammatory nanoparticles mimic glycocalyx. Chronic inflammatory bowel disease (IBD), such as Crohn’s disease and ulcerative colitis, is on the rise worldwide. The benefits of current medications are limited by problematic side effects. In the journal Angewandte Chemie, a South Korean research team has now introduced a new method of treatment. It is based on nanoparticles that mimic a special carbohydrate layer (glycocalyx) located on inflamed bowel cells, and which trigger anti-inflammatory effects in the diseased sites in the intestine.

Stomach cramps and severe diarrhea, often accompanied by significant weight loss, are some o...

Pathogenic Bacteria use a Sugar in the Intestinal Mucus Layer to Infect the Gut, study shows

The Citrobacter rodentium (orange) rely on sugars in the intestinal mucus layer (green).
Harmful gut bacteria like Citrobacter rodentium (orange) rely on sugars in the intestinal mucus layer (green).

A new study by researchers at the University of British Columbia (UBC) and BC Children’s Hospital shows the sugar sialic acid, which makes up part of the protective intestinal mucus layer, fuels disease-causing bacteria in the gut.

The findings, published in PNAS, suggest a potential treatment target for intestinal bacterial infections and a range of chronic diseases linked to gut bacteria, including inflammatory bowel disease (IBD), celiac disease, IBS and short bowel syndrome.

“Bacteria need to find a place in our intestines to take hold, establish and expand, and then they need to overcome all the different defenses that normally protect our gut,” says Dr...

Brigham researchers studying how and why certain cell types proliferate in the gut found that xanthine, which is found in coffee, tea and chocolate, may play a role in Th17 differentiation. Insights may help investigators better understand gut health and the development of conditions such as inflammatory bowel disease.

The gut is home to a cast of microbes that influence health and disease. Some types of microorganisms are thought to contribute to the development of inflammatory conditions, such as inflammatory bowel disease (IBD), but the exact cascade of events that leads from microbes to immune cells to disease remains mysterious.

A new study by investigators from Brigham and Women’s Hospital explores exactly what lead...
