CRP and lobular neoplasia: In addition, levels of anti-CRP-Ab were significantly higher in patients with active LN than in patients with inactive LN (26.8 AU (<15.0–89.4) vs. <15.0 AU (<15.0–30.6); p = 0.009) and correlated with the overall activity of SLE as assessed by the SLEDAI (rs = 0.41, p = 0.002).
