1117 Figure 1 Comparison of NET complex levels (Elastase-DNA and HMGB1-DNA) between (a) active SLE (n=49), inactive SLE (n=23) and HC (n=20); (b) ALN (n=18) and active non LN (ANLN, n=31); (c) Proliferative ( n=7) and non-Proliferative LN (n=6). All graphs represent the media with IQR. Kruskal-Wallis Test was used to assess the differences in NET complex levels between Active SLE, Inactive SLE and HC and Mann-Whitney test to assess the differences between ALN and ANLN and between Proliferative and non-Proliferative LN. Units for all graphs are in UI/ml.
