"This research highlights the importance of the microbiome-gut-brain axis and our understanding of chronic abdominal pain. Development of new disease classifiers based on microbiome data enables precision diagnostics to be developed for IBS and similar disorders. Although other studies have found differences in the gut microbiomes of patients with IBS, this study is the first to combine deep microbiome analysis with development of new diagnostic strategies," explained James Versalovic, MD, PhD, of the Department of Pathology & Immunology at Baylor College of Medicine and the Department of Pathology at Texas Children's Hospital, Houston, TX, USA. The term microbiome refers to the genetic material of all the microbes -- bacteria, fungi, protozoa, and viruses -- that live on and inside the human body.

Samples for this study were obtained from 23 preadolescent children with IBS (age 7 to 12 years) and 22 healthy controls. Participants were asked to maintain daily pain and stool diaries for two weeks and to provide stool (fecal) samples.

Investigators - Differences - Composition - Genes - Metabolites

Investigators found that there are differences in bacterial composition, bacterial genes, and fecal metabolites in children with IBS compared to healthy controls. In addition to identifying correlations of these factors with abdominal pain, they generated a highly accurate classifier using metagenomic and metabolic markers that distinguishes children with IBS from healthy controls with 80 percent or greater accuracy. This classifier assesses specific metabolites, types...
