ABSTRACT
BACKGROUND:
Various serologic markers such as anti-glycoprotein 2 antibodies and anti-Saccharomyces cerevisiae antibodies have been reported to be diagnostically useful in Crohn's disease. Mitsuyama et al. reported that antibodies to Crohn's disease peptide 353, a newly proposed serologic marker, were more useful in Japanese adults than anti-Saccharomyces. We addressed the same issue in Japanese children and adolescents.METHODS:
Prospectively enrolled subjects under 17 years old assessed and treated at 12 pediatric centers in Japan included groups with Crohn's disease, ulcerative colitis, other intestinal diseases, or good health. The 3 serum markers were analyzed by enzyme-linked immunosorbent assays.RESULTS:
Enrolled subjects, numbering 367, included 120 with Crohn's disease, 148 with ulcerative colitis, 56 with other intestinal diseases, and 43 healthy subjects. In Crohn's disease, anti-Crohn's disease peptide 353, anti-glycoprotein 2, and anti-Saccharomyces concentrations (median, 2.25, 3.0, and 8.9 U/mL) were significantly greater than in ulcerative colitis (1.1, 1.9, and 3.4; all P < 0.001), other intestinal diseases (1.1, 1.85, and 2.95; all P < 0.001), and healthy controls (1.1, 1.7, and 2.8; all P < 0.001), respectively. At 95% specificity, sensitivity of anti-Crohn's disease peptide (45.0%) was significantly higher than for anti-glycoprotein 2 (30.8%; P < 0.05) or anti-Saccharomyces (26.7%; P < 0.01).CONCLUSIONS:
Anti-Crohn's disease peptide 353 proved more useful for diagnosis of Crohn's disease in Japanese children than the other 2 markers. To our knowledge, this is the first pediatric report to that effect.Palavras-chave
