    Acute graft-versus-host disease (aGVHD) is a leading cause of non-relapse mortality after allo-HSCT, particularly affecting the gastrointestinal tract.

  • 2

    Recent studies highlight the role of microbiota dysbiosis in aGVHD pathogenesis, linking reduced microbial diversity to disease severity.

  • 3

    The MAGIC algorithm enables biomarker-driven risk stratification, improving predictions of non-relapse mortality in aGVHD patients.

  • 4

    Emerging therapies such as ruxolitinib, vedolizumab, and fecal microbiota transplantation are transforming treatment strategies for GI-aGVHD.

  • 5

    Innovative interventions targeting microbiota and immune modulation are essential for preventing and treating gastrointestinal aGVHD.
