Optimizing Therapeutic Potential of Fecal Transplant in Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD) is a chronic inflammatory condition of the gastrointestinal tract influenced by genetic, environmental, immune, and microbial factors. Reduced gut microbial diversity and elevated proinflammatory bacteria levels in IBD disrupt mucosal immunity, barrier function, and inflammatory pathways. Fecal microbiota transplantation (FMT) is a potential therapy to restore microbial balance. Studies suggest that FMT may induce remission in mild-to-moderate ulcerative colitis but show limited efficacy in Crohn's disease and pouchitis. Donor microbiota colonization correlates with remission, but varied study designs challenge findings. Further research is required to standardize FMT protocols, optimize donor selection, and ensure long-term safety.
