Continuous data presented as medians (IQR in parenthesis).
*A total of 25 patients were noted to have an attack of ascending cholangitis within 3 months of serum sampling.
†A total of106 patients had a history of IBD (all colitis), of whom 27 had active disease. Another 19 patients had undergone prior colectomy (9 with colonic dysplasia), of which 5 were experiencing pouchitis.
‡Thirty-six patients were exposed to antibiotics within 3 months of serum sampling.
ALP, alkaline phosphatase; ALT, alanine transaminase; ANA, antinuclear antibody; ASMA, anti-smooth muscle antibody; AST, aspartate transaminase; IgG, immunoglobulin G; INR, international normalised ratio; MELD, model for end-stage liver diseases; pANCA, perinuclear antineutrophil cytoplasmic antibody; UDCA, ursodeoxycholic acid; ULN, upper limit of normal; VAP, vascular adhesion protein.
