| Popis: | It was demonstrated by indirect immunofluorescence that Crohn's disease and ulcerative colitis are serologically distinct. In 59 patients with Crohn's disease, confirmed by endoscopy and histology, 23 (39%) had serum autoantibodies against exocrine pancreas; in 17 (29%) the titre was 1 : 100 or higher. In 46 patients with confirmed ulcerative colitis pancreas antibodies were demonstrated only twice, in 100 healthy control subjects only 3 times, with titres less than 1 : 100. Pancreas antibodies do not occur in high concentrations in pancreatitis; titres higher than 1 : 100 therefore suggest Crohn's disease. The pancreas antibodies of patients with Crohn's disease were predominantly immunoglobulins IgA and IgG, twice they were IgD and once IgM, never IgE. In 6 patients the pancreas antibodies fixed complement. Autoantibodies against intestinal goblet cells were found only in patients with ulcerative colitis (13 of 46 = 28%). The titres range was from 1 : 10 to 1 : 1000. The goblet-cell antibodies consisted only of IgA and IgG, never reacting with complement. These results indicate that determining pancreas and goblet-cell antibodies alone will make it possible to diagnose either Crohn's disease or ulcerative colitis in more than a quarter of patients with chronic inflammatory intestinal disease. |
