  1. The pathogenic 16/6 idiotype in patients with silica associated systemic lupus erythematosus (SLE) and uranium miners with increased risk for development of SLE.

    Article - En anglais


    To investigate the prevalence of the 16/6 idiotype (16/6 Id), a major cross reactive idiotype of anti-DNA antibodies involved in the pathogenesis of experimental lupus, in subjects with an exogenous risk for the development of systemic lupus erythematosus (SLE).


    The titer of 16/6 Id was determined by ELISA in sera of uranium miners exposed to heavy quartz dust : 15 developed definite and 12 probable SLE, 34 had clinical symptoms, and 27 had only serological signs (medium to high titer anti-dsDNA antibodies) of possible connective tissue disease (CTD) development.


    The prevalence of 16/6 Id was higher in all groups compared to healthy blood donors.

    It was 18.5% in miners with SLE (definite and probable) and 22.2-26.5% in miners with clinical and/or serological signs for developing CTD.

    All 16/6 Id positive miners were positive for anti-dsDNA antibodies and other autoantibodies associated with CTD.

    The prevalence of 16/6 Id in anti-dsDNA positive miners correlated slightly with CTD/SLE symptoms : 55.6% in patients with SLE. 47.4% in miners with possible CTD/SLE, and 22.2% in miners without CTD symptoms.

    Further, at short term followup, disease progressed in 2 miners of the 16/6 Id positive, but not in 16/6 Id negative miners. (...)
