Gastro Hep Advances The Microbiome in Quiescent Crohn’s Disease With Persistent Symptoms Show Disruptions in Microbial Sulfur and Tryptophan PathwaysVolume 3, Issue 2P167-1772024This research investigates how the gut's microbial community, or microbiome, differs in individuals with Crohn's disease (CD) who have persistent symptoms despite being in a state of quiescent disease (no inflammation). The study found that patients with symptoms had a less-diverse microbiome and significant disruptions in key metabolic pathways, particularly those involving sulfur and tryptophan. Specifically, these patients showed an increase in bacteria usually found in the mouth and those that produce sulfide, while also showing a decrease in beneficial microbes that produce compounds like butyrate and indole. These findings suggest that lasting alterations to the microbiome, even after inflammation subsides, may be the underlying cause of persistent symptoms in quiescent CD.
