As the results
in our earlier paper6 implied that anti-SSA, but not
anti-dsDNA, would be enriched in SLE-IC and as
anti-dsDNA showed the lowest degree of enrichment
of all investigated autoantibody specificities
in the present study (Figure 1), we thereafter compared
the degree of enrichment between antidsDNA
and the other autoantibody specificities.
Antibodies directed against the RNA-associated
antigens RNP/Sm and SSA/Ro52 were significantly
more enriched in the PEG precipitates than were
anti-dsDNA antibodies (RNP/Sm: p ¼ 0.0368,
SSA/Ro52 p ¼ 0.0208)
