To identify discriminatory circulating cytokine profiles and novel biomarker candidates capable of distinguishing active ulcerative colitis from Crohn’s disease.
Measured 27 systemic cytokines using flow cytometry-based assays in 138 patients with inflammatory bowel disease, alongside an extended panel of 21 additional cytokines in a subset of 67 patients.
Assessed discriminatory potential using individual mediator evaluation and multivariable modeling approaches, including logistic regression, hierarchical clustering, and principal component analysis.
Individual cytokines including eotaxin-1, MIP-1β, and TRAIL demonstrated fair discriminatory capacity, whereas integrated multivariable models achieved superior classification performance.
Active ulcerative colitis was characterized by mediators associated with eosinophil-, mastocyte-, and neutrophil-driven inflammation and tissue repair (including IL-5, GM-CSF, MIP-1β, and TRAIL), whereas active Crohn’s disease was driven by Th1/Th17 immunity, myeloid activation, and neuroimmune remodeling (including IL-1β, IL-4, and MIP-1α).
