Study of IgA intestinal deposit and ASCA/anti-OmpC antibody detection in supernatants for each clinical group.

IgA intestinal deposit was evaluated by direct immunofluorescence (DIF). The agreement between IgA intestinal deposit and ASCA / anti-OmpC antibody detection in supernatants of each clinical group was evaluated using Cohen's kappa coefficient. ASCA: Anti-Saccharomyces cerevisiae antibodies, anti-OmpC: anti-outer membrane porine C antibodies, CD: Crohn’s disease, UC: ulcerative colitis, Controls: patients suffering from functional intestinal disorders but not from CD or UC.
