title: Goblet cell autoantibodies in patients with inflammatory bowel disease and their first-degree relatives.
abstract: OBJECTIVE
  Crohn's disease and ulcerative colitis show a familial aggregation. In both diseases, anti-goblet cell autoantibodies (GABs) have been described. The aim of this study was to define the role of GABs in the pathogenesis of inflammatory bowel disease.
  
  
  METHODS
  The study population comprised 61 patients with ulcerative colitis, 76 patients with Crohn's disease, 101 first-degree relatives of patients with ulcerative colitis, and 105 first-degree relatives of patients with Crohn's disease. Thirty-five patients with infectious enterocolitis and 56 healthy unrelated subjects served as controls. Autoantibodies were detected by indirect immunofluorescence.
  
  
  RESULTS
  Thirty-nine percent of patients with ulcerative colitis (24 of 61) and 30% of patients with Crohn's disease (23 of 76) were positive for GABs. GABs were detected in 21% (21 of 101) of first-degree relatives of patients with ulcerative colitis and in 19% (20 of 105) of first-degree relatives of patients with Crohn's disease. In patients with infectious enterocolitis and in healthy controls, GABs were seen in 3% (1 of 35) and 2% (1 of 56), respectively. The differences between control groups and both groups of patients or their first-degree relatives were significant.
  
  
  CONCLUSIONS
  The high prevalence in first-degree relatives suggests that GABs may represent a marker characterizing susceptibility to inflammatory bowel disease.
