High prevalence rates of adult silent coeliac disease, as seen in Sweden, must be expected in Denmark.

Aim: To disclose the prevalence of adult "silent" coeliac disease in Denmark and Sweden.

Experimental Design: 1573 Danish and 1866 Swedish healthy blood donors were screened for the presence of serum anti-gliadin antibodies (AGA) by enzyme-linked immunosorbent assay. AGA-positive serum samples were further analysed for IgA anti-endomysium antibodies (EmA) by indirect immunofluorescence microscopy.

Tissue transglutaminase and endomysial autoantibodies measured in an historical cohort of children and young adults in whom coeliac disease was suspected.

Objective: To evaluate whether anti-endomysial and anti-transglutaminase antibodies are relevant important markers of coeliac disease in an historical group of patient sera.

Design: Sera from 196 children suspected to suffer from coeliac disease were analysed for these antibodies.

Methods: A total of 233 serum samples were obtained simultaneously with a biopsy.

Treatment of Helicobacter pylori in children with recurrent abdominal pain.

Background: The role of Helicobacter pylori remains unclear in children with recurrent abdominal pain (RAP). In this study children with RAP were included in a double blind treatment study to elucidate whether symptoms disappear in children with a H. pylori infection and RAP, if the bacteria are eradicated.

Different patterns of Helicobacter pylori adherence to gastric mucosa cells in children and adults. An ultrastructural study.

Background: Infection with Helicobacter pylori in childhood may be the initiation of a lifelong coexistence between microorganisms and epithelial cells resulting in chronic inflammation. The adhesion pattern of H. pylori found in antral biopsies from a group of H.

Interobserver variation in diagnosing coeliac disease. A joint study by Danish and Swedish pathologists.

There is an almost 40-fold difference in incidence rates of symptomatic coeliac disease between Denmark and Sweden. In an attempt to explain this difference, the present study focused on the interobserver agreement when pathologists were assessing small intestinal biopsy specimens from children suspected of suffering from coeliac disease. The study was performed on 90 biopsy specimens from 73 children.
