C4A and lobular neoplasia: The frequency of CD8+CD45RO+ TM cells in patients with LN was negatively correlated with the number of white blood cells (p=0.007), haemoglobin (p=0.003), platelet (p=0.03), and serum complements C3 (p=0.008) and C4 (p=0.03), but it was positively correlated with serum levels of IgG (p=0.04) and ESR (p=0.006), and SLEDAI score (p=0.001) (figure 1A–C).
