Renal tubulointerstitial injury often leads to interstitial fibrosis and tubular
atrophy (IF/TA). IF/TA is typically assessed in the renal cortex and can be
objectively quantitated with computerized image analysis (IA). However, the human
medulla accounts for a substantial proportion of the nephron; therefore,
medullary scarring will have important cortical consequences and may parallel
overall chronic renal injury. Trichrome, periodic acid-Schiff (PAS), and collagen
III immunohistochemistry (IHC) were visually examined and quantitated on scanned
whole slide images (WSIs) (N = 67 cases). When tuned to measure fibrosis, IA of
trichrome and Trichrome-PAS (T-P) WSIs correlated for all anatomic compartments
(among cortex, medulla, and entire tissue, r = 0.84 to 0.89, P all <0.0001); and
collagen III deposition correlated between compartments (r = 0.69 to 0.89, P
<0.0001 to 0.0002); however, trichrome and T-P measures did not correlate with
collagen deposition, suggesting heterogeneous contributions to extracellular
matrix deposition. Epithelial cell mass (EPCM) correlated between cortex and
medulla when measured with cytokeratin IHC and with the trichrome red portion (r
= 0.85 and 0.66, respectively, all P < 0.0001). Visual assessment also correlated
between compartments for fibrosis and EPCM. Correlations were found between
increasing medullary inner stripe (IS) width and fibrosis in all of the tissue
and the medulla by trichrome morphometry (r = 0.56, P < 0.0001, and r = 0.48, P =
0.00008, respectively). Weak correlations were found between increasing IS width
and decreasing visual assessment of all tissue EPCM. Microvessel density (MVD)
and microvessel area (MVA) measured using a MVD algorithm applied to CD34 IHC
correlated significantly between all compartments (r = 0.76 to 0.87 for MVD and
0.71 to 0.87 for MVA, P all < 0.0001). Overall, these findings demonstrate the
interrelatedness of the cortex and medulla and the importance of considering the
renal parenchyma as a whole.
