Aims: To evaluate the diagnostic accuracy of ANCA and ASCA in children with suspected IBD, and to see whether different commercially available assays (indirect immunofluorescence vs. ELISA) agree well enough in terms of analytical performance. Patients and Methods: Sixty-nine children (30 males, 39 females, age range 2\u201318 years) with suspicion of IBD entered the study. Before colonoscopy, a blood sample was also drawn to assess ASCA and ANCA. Results: A diagnosis of IBD was established in 47 patients; the remainder had infective or other causes of colitis. For ulcerative colitis, the association ASCA\u2013\/ANCA+ had 70% sensitivity and 86% specificity, with a positive predictive value of 82%. The association ASCA+\/ANCA\u2013 had 86% sensitivity and 93% specificity for Crohn\u2019s disease, with a positive predictive value of 75%. Conclusion: Although more experience is needed to state the diagnostic power of serologic assay, determination of ANCA and ASCA in IBD children may help both in distinguish these conditions from other entitiesand ulcerative colitis from Crohn\u2019s disease, particularly in doubtful cases.<\/jats:p>","DOI":"10.1159\/000109928","type":"journal-article","created":{"date-parts":[[2007,10,19]],"date-time":"2007-10-19T11:00:58Z","timestamp":1192791658000},"page":"210-214","source":"Crossref","is-referenced-by-count":13,"title":["Diagnostic
