Sera of 64 patients with chronic inflammatory bowel disease (IBD) were screened for antibodies against neutrophil cytoplasmic antigens (ANCA) using an indirect immunofluorescence technique on ethanol-fixed human neutrophil granulocytes.20 of 34 sera (59 %) from patients with ulcerative colitis (UC) produced a fine-granular and perinuclear ANCA staining pattern (p-ANCA) clearly different from the typical diffuse and granular cytoplasmic ANCA fluorescence (c-ANCA, synonym ACPA) seen in active Wegener's granulomatosis (WG).The majority of the 20 p-ANCA positive UC patients had a high inflammatory disease activity.Among the 14 p-ANCA negative UC patients nine were without steroids; five of them had active disease, two were inactive and two had previously undergone colectomy.The remaining five patients still had active disease but received steroids for more than 4 weeks.Only 3 of the 30 sera from patients with Crohn's disease (CD) showed positive p-ANCA reactions. To narrow the specificity of the p-ANCA reaction all 64 sera were tested by ELISA for antibodies against anti-proteinase-3 (WG specific) and on HEp-2 cells for antinuclear (ANA) and anticytoplasmic antibodies.Ten p-ANCA positive UC sera were also tested in a myeloperoxidase ELISA.Only one UC serum reacted positively in the proteinase-3-ELISA and another one produced a weakly positive anti-nucleolar ANA fluorescence on HEp-2 cells.None of the tested sera reacted with myeloperoxidase suggesting that the p-ANCA staining pattern of granulocytes is not restricted to anti- myeloperoxidase antibodies as reported in the literature. These preliminary results suggest that sera from patients with active UC contain a new type of perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA) and that ANCA screening may be of value in differentiating active UC from CD.
