Prevalence and significance of perinuclear anti-neutrophil antibodies (pANCA) in Romanian patients with Crohn's disease and ulcerative colitis.

Introduction: Antineutrophil cytoplasmic antibodies (ANCA) are known as a serologic marker of immune disturbances in IBD. The most specific are perinuclear ANCA (pANCA). The aim of this study was to investigate their significance for the diagnosis of inflammatory bowel disease (IBD) in Romania.

Significance of anti-sacharomices cerevisiae antibodies (ASCA) in patients with inflammatory bowel diseases in Romania.

Introduction: Anti-Sacharomyces cerevisiae antibodies (ASCA) represent the immunologic marker correlated with Crohn's disease because of their high specificity (80-95%). The aim of this study is to confirm their value in a Romanian population with IBD.

Material And Methods: A prospective longitudinal study was performed, which included patients admitted to Center of Gastroenterology and Hepatology Fundeni, Bucharest, in 2000 with ulcerative colitis (33 patients) - UC group, or Crohn's disease (40 patients) - CD group, and a control group (C) consisting of 22 healthy subjects.
