Assessment of coeliac disease prevalence in patients with Down syndrome in Poland – a multi-centre study
OBJECTIVE This study was undertaken to investigate the prevalence of celiac disease in children and adolescents with Down syndrome. MATERIAL AND METHODS Forty-three children and adolescents with Down syndrome were screened for IgA-antigliadin antibodies (AGA) and IgA-antiendomysium antibodies (EMA). Patients found to be either AGA- or EMA-positive were investigated further with intestinal biopsy. RESULTS None of the 43 patients had known celiac disease at entry into the study; 37% (16/43) were found to have AGA levels above normal, and 16% (7/43) to be EMA-positive. Of the 15 patients who underwent biopsy, 8 manifested villous atrophy. Villous atrophy was present in all 7 of the EMA-positive patients, whereas the villi were normal in 7 of the 13 AGA-positive patients who underwent biopsy. CONCLUSIONS EMA is a good immunologic marker for use in screening for celiac disease, and screening is justified in patients with Down syndrome.
