Gut microbiota as a potential predictor of therapeutic response in adults with Crohn’s disease: A systematic review

The overall results suggest good performance of microbial parameters as a novel biomarker of therapeutic response. However, there are variations across individual studies, probably related to the methodology of assessing microbial communities and the therapeutic agent used. Future multicenter studies integrating microbial, clinical, and metabolomic data are warranted to develop predictive models for personalized therapy in CD.
