    Ustekinumab responders in ulcerative colitis had significantly higher baseline eosinophil counts compared to non-responders.

    By week 8, ustekinumab responders showed a greater decline in eosinophil counts than non-responders.

    In Crohn's disease, ustekinumab responders also exhibited higher baseline eosinophil counts and significant reductions by week 8.

  • 4

    No significant differences in eosinophil counts were observed among patients treated with adalimumab or vedolizumab.

    Eosinophil reduction is a marker for early response to ustekinumab in inflammatory bowel disease.
