PRTN3 and ganglioneuroma: Neutrophils in PR3-ANCA GN were correlated with crescentic class (r=0.5085, p=0.0094) and less focal class ANCA GN (r=-0.4525, p=0.0232), interstitial inflammation (i, r=0.5723, p=0.0043), tubulitis (t, r=0.6593, p=0.0006), interstitial fibrosis (ci, r=0.5022, p=0.0105), and peritubular capillaritis (ptc, r=0.4578, p=0.0280), reflecting active lesions in the majority of histopathological findings (Figure 7B).
