50: Translating the Microbiome to the Clinic

Porcari S et al., Cell - Perspective reviewing current diagnostic and therapeutic advances in gut microbiome research and outlining the methodological, biological, regulatory, and educational actions needed to move microbiome science into clinical practice. Key terms: microbiome, faecal microbiota transplantation, diagnostics, therapeutics, standardization.

Study Highlights:
The authors synthesize evidence that microbiome diagnostics can aid in disease detection and therapy prediction (notably CRC, IBD, and cancer immunotherapy response) and that fecal microbiota transplantation is established for recurrent C. difficile infection but limited elsewhere. They highlight emerging artificial microbiome therapeutics (defined consortia, single-strain biotherapeutics, bacteriophages) and note some approvals for rCDI. Key barriers include biological heterogeneity, lack of standardized protocols, variable trial designs, donor-selection and safety concerns, and direct-to-consumer testing variability. The article calls for standardization, improved trial design, mechanistic studies, and clinician education to accelerate clinical integration.

Conclusion:
Microbiome research provides promising diagnostic and therapeutic opportunities, but broad clinical integration requires standardized methods, stronger mechanistic and clinical evidence, refined trial design, regulatory harmonization, and targeted education for clinicians to enable reliable, equitable implementation.
