title: C-ANCA and p-ANCA in patients with Crohn's disease.
abstract: In 32 patients suffering from various stages of activity of Crohn's disease, c-ANCA and p-ANCA in serum were examined. Altogether, 54 blood samples were examined. In 21 patients of 32, i.e. 65.6%, at least in one examination of c-ANCA in serum the value was higher than 9 units (positive finding). In 10 patients of 32, i.e. 32.2%, at least in one examination of p-ANCA in serum the value was higher than 9 units (positive finding). In the case of high activity of Crohn's disease, c-ANCA in serum were higher than 9 units (positive finding) in 69.6% examinations, in case of low activity, values of c-ANCA in serum were higher than 9 units (positive finding) only in 9.5% examinations. p-ANCA in serum were, when the activity was high, positive in 46.1% examinations, while when the activity of Crohn's disease was low, p-ANCA were positive in 9.5%. The question of specificity of findings is discussed.
