  1. Autoantibodies in Estonia and sweden, populations with different responses to allergens.

    Article - En anglais


    There are substantial differences in immune-mediated disease prevalence between different countries and populations which cannot be explained by genetic variability.


    To compare the prevalence of antinuclear (ANA), antimitochondrial, antireticulin, liver-kidney microsomal, parietal cell, thyroid microsomal and double-stranded DNA (dsDNA) antibodies among adults aged 20-44 years in two towns, i.e. in Tartu, Estonia (n=448) and in Uppsala, Sweden (n=532) with a low and a high prevalence of allergy.


    For autoantibody detection, standard indirect immunofluorescence tests on tissue and Chritidia lucilia antigenic preparations were used (sera were diluted starting from 1 : 10).


    The prevalence of ANA was lower in Tartu than in Uppsala (3 vs. 10% among males and 1 1 vs. 16% among females ; p<0.01 and p<0.1, respectively).

    Furthermore, dsDNA antibody-positive cases were only identified in Uppsala.

    The largest difference between the two populations was revealed for IgM type ANA, both among males (1 vs. 6% ; p<0.02) and females (5 vs. 11% : p<0.01).

    In addition, the antibody titers were lower in Tartu than in Uppsala (p<0.05).

    The prevalence of other autoantibodies was similar in the two towns.


    The findings could support that Th2-like immune responses are commoner in Sweden than in Estonia, as previously suggested by the higher prevalence of allergy.
