CD68 and kidney disorder: Identical results were obtained with CD68+ macrophage counts in the glomerular compartment, which did not show any correlation with clinical parameters, while CD68+ tubulointerstitial staining demonstrated a significant correlation with both initial (<i>p</i> = 0.002) and final eGFRs (<i>p</i> = 0.0014), proteinuria (<i>p</i> = 0.010), and interstitial fibrosis (<i>p</i> < 0.001), as well as with renal disease progression (<i>p</i> = 0.005).
