Methods: The concentration of relative AOPPs (rAOPP; concentration
of AOPPs divided by albumin level) were measured in 68
subjects with ulcerative colitis (UC), 50 subjects with Crohn’s
disease (CD) and 45 healthy volunteers, and related to disease
phenotype, clinical and biochemical activity, and therapeutic strategy.
Diagnostic utility of rAOPP was evaluated by ROC analysis.
