AI-Guided Multi-Omic Microbiome Modulation Improves Clinical and Inflammatory Outcomes in Refractory IBD: A Real-World Study

Inflammatory bowel disease (IBD) remains difficult to manage in patients who fail multiple therapeutic lines, and growing evidence suggests that alterations in the gut microbiome contribute to persistent symptoms and inflammatory activity. This study evaluated a three-month, AI-guided, multi-omic personalized microbiome modulation program in adults with treatment-refractory IBD. Baseline stool metagenomic sequencing, blood biomarkers, micronutrient panels, and clinical data were integrated through an artificial intelligence platform to generate individualized plans combining dietary adjustments, targeted synbiotics, selective antimicrobials, and micronutrient correction. Clinical outcomes, inflammatory markers, and microbial signatures were reassessed after three months. Across 358 participants, stool frequency decreased substantially, urgency and rectal bleeding resolved in most patients, and over 70% reported a “much improved” overall condition. Inflammatory biomarkers showed marked normalization, with reductions in hs-CRP and fecal calprotectin observed in over 85% of cases. Micronutrient deficiencies, particularly iron and zinc, also improved, and beneficial microbial taxa such as Faecalibacterium prausnitzii, Bifidobacterium longum, and Akkermansia muciniphila increased significantly. These findings suggest that personalized, multi-omic microbiome modulation may support clinically meaningful improvements by targeting microbial, metabolic, and immune imbalances rather than symptoms alone. While encouraging, these results require confirmation in randomized controlled studies.
