- Objective. A national change in infant feeding recommendations was proposed in 1996 in Sweden: a slow introduction to gluten during weaning was stressed, the recommendation being introduction at 4 instead of 6 months of age. The aim of the present study was to compare the prevalence of celiac disease in healthy young children born before and after the new feeding recommendations in 1996. Material and methods. Sera from 679 children at a median age of 2.9 years (range 2.5-4.2 years) born between January 1996 and November 1997 were investigated with IgA-antigliadin antibodies (AGA) and IgA-endomysial autoantibodies (EMA) and compared with 690 age-matched children born between July 1992 and June 1993. Children with a positive test for EMA and AGA or EMA only were re-tested, and if positive at follow up, investigated with intestinal biopsy. Results. At baseline, 2.2% (15/679) children were positive for EMA and another 0.6% (4/679) for both EMA and AGA. One child refused to be re-tested and eight children were still EMA positive at follow-up. Intestinal biopsy was performed in seven children (one declined biopsy), of whom three showed total villous atrophy. Two children with EMA titers 1:640, respectively, refused further participation in the study, but were strongly suspected to have celiac disease. In total, 0.7% (5/679) (95% confidence interval (CI) = 0.1-1.4%) were considered to have celiac disease compared with 1.3% (9/690) (95% CI = 0.4-2.2%) in the control group (p = 0.4217). In addition, 0.3% of the children were diagnosed with symptomatic celiac disease compared with 0.7% in controls (p = 0.0134). Conclusions. The prevalence of symptomatic celiac disease declined after the infant dietary recommendations were introduced in 1996, but we could not find any difference in undiagnosed celiac disease between the screened children born before and those born after 1996. © 2006 Taylor & Francis.

- An interdisciplinary research group entitled ”Twincities Research Group” has been initiated at Linköping University. The term twin cities refer to the Swedish cities Linköping and Norrköping, neighbours that are nearly equal in size. These two cities, located within a distance of only 40 km, are governed by the same county council and consequently have the same health care structure. However, health is remarkably different in these twin cities. The comparison of public health in these two cities during the development from the industrial to the post-industrial era has a design similar to classical experiments with a control and an experiment group, since the social history and the socio-economic structures of the cities are radically different. Through an interdisciplinary research design including historical, epidemiological and clinical competence we have a unique opportunity to increase our understanding of how social environment may affect public health.

- Aim: To evaluate possible differences between children with anti-endomysium antibodies (EMA) positivity and normal small bowel mucosa and children with positive EMA and an enteropathy diagnosed as celiac disease (CD).Methods: Children with suspected CD and positive EMA (≥1/10) undergoing small bowel biopsy during 1996 to 2002, were investigated (n = 133). Data registered were: year and month of birth, timing of the first biopsy, sex, heredity for CD, dermatitis herpetiformis and diabetes mellitus and outcome of the anti-gliadin antibody test (AGA). The case group, with EMA positivity and normal histology (n = 39; 59% female, mean age at the first biopsy 7.3 years, range 1.4–16), was compared with the disease control group, with positive EMA and a biopsy suggestive and further on diagnosed as CD (n = 94; 56% female; mean age 7.6 years at the first biopsy, range 0.70–17).Results: AGA positivity and heredity for CD were found to predict the outcome of a pathological jejunal mucosa. Nineteen of the 39 children in the case group were rebiopsied of whom 11 had developed an enteropathy during a follow-up period of 2–7 years (median 4.5 years).Conclusions: EMA positivity in the absence of small bowel enteropathy could be a very early predictor for later overt CD, and necessitates further follow-up, especially if the child is AGA positive and there is a family history of CD.
