The gut microbiota of patients with Inflammatory Bowel Disease (IBD) may have a role in disease aetiology and course [1]. Patients with IBD often have dysbiotic microbiota, with lower microbial diversity and cell counts, with both absolute and relative abundance of commensal microorganisms [2, 3]. Conversely, during remission following anti-inflammatory therapy, the gut microbiota has been observed to shift to a more eubiosis-like composition [3–6]. Furthermore, lower proportions of taxa with pro-inflammatory properties and mucus-degrading bacteria, as well as higher proportions of short-chain fatty acid-producing bacteria, have been associated with a higher likelihood of favourable outcomes with medical treatment [3, 5, 6]. In this study, Caenepeel and colleagues monitored changes in intestinal microbiota and stool features in order to develop and validate a predictive model to assist clinicians in determining a patient-specific therapeutic strategy.
