CD163 and lobular neoplasia: Accordingly, serological and urinary sCD163/creatinuria ratio levels were compared to eGFR levels in a cross-sectional analysis from 139 LN patients, with a weak association reported for PCR (rho = −0.291; p = 8 × 10−6), urinary sCD163/creatinuria ratio (rho = −0.228; p = 0.0015), and anti-Sm Abs (rho = 0.222; p = 0.001) (Fig. 5A–C).
