In the former study, we assessed the urinary KIM-1 level and tubular KIM-1 expression in kidney biopsies of SLE patients and their association with histological markers of renal damage (61), and we found that the urinary KIM-1 levels were significantly correlated with proteinuria (R = 0.39, p = 0.004) and with tubular damage (R = 0.31, p = 0.01). This evidence concerns the gene HAVCR1 and systemic lupus erythematosus.
