Gene Expression Profile Associated With Crohn's Disease and Microbial Community

Crohn's and other inflammatory bowel diseases are painful and debilitating, but there are no known cures for the diseases.

Crohn's and other inflammatory bowel diseases are painful and debilitating, but there are no known cures for the diseases. The symptoms have to be managed by the individual with professional help. It is widely thought that IBDs develop as a result of an individual's genetic make-up, their gut microbiota, and environmental cues, though it is not fully understood how these factors promote IBDs.

A new study in the Journal of Clinical Investigation identifies a specific gene expression profile and microbial community associated with Crohn's disease. Lee Denson and colleagues at Cincinnati Children's Hospital Medical Center compared the intestines of healthy patients to pediatric Crohn's disease patients. Crohn's disease patients had altered expression of 2 genes, DUOX2 and APOA1, as well as a distinct microbial community. Furthermore, APOA1 expression and microbial abundance could be used to predict clinical outcomes in Crohn's disease patients.

Small bowel atresia - Types - Diagnosis - Treatment - Operation - Effect
The small bowel is the section of bowel between the stomach and the large bowel (colon). It is about 300cm long in a newborn baby at term and its function is to absorb food.

Volvulus
A volvulus is surgical condition that results in a loop of the bowel twisting on itself. This can be a life-threatening condition due to the loss of blood supply and accumulation of toxic gases and fluids in the portion of the obstructed bowel segment.

TNF Inhibitors for Treatment of Bowel Disease Not Associated With Cancer Risk
In a study of 56,000 patients with inflammatory bowel disease, use of a popular class of medications known as tumor necrosis factor alpha antagonists was not associated with an increased risk of cancer over a median follow-up of 3.7 years.
