[p-ANCA and ASCA antibodies in the differential diagnosis between ulcerative rectocolitis and Crohn's disease].

Unlabelled: Anti-Saccaromyces cerevisiae antibodies (ASCA) seem to be associated with Crohn's disease (CD), while anti-neutrophil cytoplasm antibodies (p-ANCA) seem to be a recognised marker for ulcerative colitis (UC).

Aim: Of our study was to determine whether the presence of ASCA and p-ANCA antibodies could differentiate CD from UC and IBD from aspecific chronic colitis (ACC).

Methods: Serum samples were obtained from 23 patients with CD and 32 with UC, and from 13 patients with aspecific chronic colitis.
