Community Types of the Human Gut Virome are Associated with Endoscopic Outcome in Ulcerative Colitis.
Background: Inflammatory bowel disease [IBD] is a major debilitating disease. Recently, the gut microbiota has gained attention as an important factor involved in the pathophysiology of IBD. As a complement to the established bacterial 'enterotypes' associated with IBD, we focused here on viruses. We investigated the intestinal virome of IBD patients undergoing biological therapy for the presence of virome configurations associated with IBD, and to uncover how those configurations are associated with therapeutic success.
Methods: Viral-like particle enrichment followed by deep sequencing was performed on 432 faecal samples from 181 IBD patients starting biological therapy. Redundancy analysis and Dirichlet Multinomial Mixtures were applied to determine covariates of the virome composition and to condense the gut virota into 'viral community types', respectively.
Results: Patients were stratified based on unsupervised clustering into two viral community types. Community type CA showed a low α-diversity and a high relative abundance of Caudoviricetes [non-CrAss] phages and was associated with the dysbiotic Bact2-enterotype. Community type CrM showed a high α-diversity and a high relative abundance of Crassvirales and Malgrandaviricetes phages. During post-interventional analysis, endoscopic outcome was associated with gut virome composition. Remitting UC patients had a high percentage of community type CrM, a high Shannon diversity and a low lysogenic potential. Pre-interventional analyses also identified five novel phages associated with treatment success.
Conclusions: This study proposed two gut virome configurations that may be involved in the pathophysiology of IBD. Interestingly, those viral configurations are further associated with therapeutic success, suggesting a potential clinical relevance.
