Prevalence of Anti-tissue Transglutaminase Antibodies and Celiac Disease in Children With Inflammatory Bowel Disease
Celiac disease can occur in children with inflammatory bowel disease (IBD) and poses a diagnostic challenge. We evaluated the presence of anti-tissue transglutaminase (tTG) antibodies and celiac disease among children with IBD.Methods:
In a retrospective chart review, we assessed the prevalence of tTG antibodies and celiac disease and compared with a control group of children with gastrointestinal symptoms without IBD.Results:
Study population included 130 children with IBD and 257 in the control group. Abnormal tTG levels were found in 6 and 20 patients, respectively (4.6% vs 7.8%, P = 0.24). One patient with IBD and 12 in the control group had celiac disease (0.8% vs 4.7%, P = 0.07).Conclusions:
False-positive tTG can occur in children with IBD. The prevalence of celiac disease is not increased in children with IBD compared with non-IBD children with gastrointestinal symptoms and is similar to that in the general population.
