Results of coeliac disease screening in Estonia in 1990-1994.

In the period of 1990-94, 2895 individuals (629 children with suspicion of coeliac disease selected throughout Estonia; 700 consecutively hospitalized children; 105 children with atopic dermatitis; 1461 inhabitants of a small Estonian town) were serologically screened for coeliac disease. The enzyme-linked immunosorbent assay was used for antigliadin antibody determinations and R1-type antireticulin antibodies were detected using an indirect immunofluorescence method. Coeliac disease was diagnosed according to recent criteria recommended by the European Society for Paediatric Gastroenterology and Nutrition. Antigliadin antibody testing was positive in 44 (3.1%) of 1434 children studied, and in 33 of whom coeliac disease was confirmed. In all the coeliac patients R1-type antireticulin antibody test was positive. However, 52 (3.5%) of 1461 adults studied who did not have coeliac disease had positive antigliadin antibody test but negative antireticulin antibody test. Thus, in Estonia, the antigliadin antibody test can be used in screening for coeliac disease in children but not in adults.
