[Significance of serum antibodies ANCA, ASCA, ABBA in diagnostics of idiopathic intestinal inflammations].
BACKGROUND
Crohn's disease and ulcerative colitis still remain a heterogeneous group of diseases with an unclear aetiology. Serologic methods play important role in their diagnosing though there is still not an ideal marker. We tried to determine the importance of serological testing of ASCA IgA, IgG, ANCA, ABBA antibodies in patients with ulcerative colitis and Crohn's disease.


RESULTS
ASCA IgG, ASCA IgA; ANCA, ABBA antibodies and C-reactive protein were detected by indirect fluorescence assay. ASCA IgA, ASCA IgG, ABBA, ANCA were examined in 40 patients (28 Crohn's disease, 12 ulcerative colitis, 32 health controls). Specificity of ASCA IgA, IgG in CD patients was high (both 96.2%), specificity ANCA in UC 100%. ABBA antibodies had low sensitivity and specificity in both diseases. Combination of ASCA, ANCA, ABBA makes the specificity higher.


CONCLUSIONS
We showed the importance of combination ASCA, ANCA with ABBA antibodies to improve the serological diagnosing of IBD.
