We determined no differences in specific autoantibody
levels in active and inactive SLE in PEG precipitates
nor in autoantibody levels not corrected
for IgG content (data not included) or after correction
for IgG levels (Figure 3(a)). In sera, antinucleosome
levels were higher in inactive SLE
(Figure 3(b)). Furthermore, when the ratio between
the normalized autoantibody levels in PEG precipitates
and sera were compared (similar to in
Figure 1) in active versus inactive disease, there
was no difference in enrichment for any of the
investigated autoantibody specificities (Figure 3(c))
