Objective:

To evaluate the association between peripheral blood eosinophilia (PBE) and long-term outcomes in children and adults with inflammatory bowel diseases (IBDs).

Key Findings:
  • PBE prevalence was 13% in the IBD group versus 5% in controls (p < 0.001).
  • PBE was more prevalent in ulcerative colitis (16.1%) than Crohn's disease (10.6%).
  • PBE was a significant predictor of severe disease course (HR = 1.49, p < 0.001).
  • PBE predicted time-to-hospitalization (HR = 1.24), corticosteroid use (HR = 1.32), and need for biologics (HR = 1.27).
Interpretation:

PBE serves as a marker for adverse outcomes in IBD, indicating a potential target for future therapies.

Limitations:
  • Study limited to a single national cohort, which may affect generalizability.
  • Potential confounding factors not fully accounted for in the analysis.
Conclusion:

PBE is associated with severe disease progression in IBD, supporting its use as a prognostic marker.
