Levels of sCD163 were associated with positivity of antichromatin autoantibodies (988.22 ng/ml ± 299.05 ng/ml vs. 747.34 ng/ml ± 300.38 ng/ml; P = 0.0255) (Figure 6E), and, as observed for sMer, correlated with lupus disease activity as assessed by SLEDAI score (r = 0.35; P = 0.0257) (Figure 6F). The gene discussed is CD163; the disease is systemic lupus erythematosus.
