ABSTRACT
Objective To investigate the biological markers and their clinical significance in diagnosis and differential diagnosis of inlfammatory bowel disease (IBD) in children.Methods The study had 22 cases of IBD including 6 cases of ulcerative colitis (UC) and 16 cases of Crohn’s Disease (CD). Twenty-four children without IBD were selected as controls. The serum perinuclear anti-neutrophil cytoplasmic antibody (pNACA) was measured by indirect immune lfuorescence method. The serum anti-saccharomyces cerevisiae antibody (ASCA) IgG and IgA, anti-B mannose glycoside antibody (AMCA) IgG, anti-B glycoside sugar shell antibody (ACCA) IgA, Anti-bacterial lfagellin antibody (Anti-cBir1) IgG, and the fecal calprotectin (FC) were determined by Enzyme linked immunosorbent assay (ELISA). Results The positive rate of serum pANCA was 100% in 6 cases of UC while it was negative in CD cases and control, and there was significant difference among three groups (Pserum ACCA IgA and that of Anti-cBir1-IgG were 62.5% and the positive rate of ACCA IgA was 37.5%. Meanwhile, all of them were negative in UC cases and control. There were signiifcant differences among three groups (P<0.01). The positive rate of FC was 100% in children with IBD. It was signiifcantly higher than the positive rate in control group, 54.2% (Pserum pANCA is a speciifc index for the diagnosis of UC. The serum ACCA IgA, AMCA IgG, ASCA IgG and IgA, and Anti-cBir1 IgG were speciifc to some extent in the diagnosis of CD. Increased FC can relfect the activity of IBD, but cannot be used for the differential diagnosis of IBD and non IBD.
