Centrilobular injury (CLI) is defined as the presence of perivenular mononuclear inflammation, hepatocyte dropout, and extravasated erythrocytes. In pediatric liver allografts, CLI has been associated with advanced fibrosis and chronic rejection (CR). We sought to better characterize the clinicopathologic features of CLI in the setting of T cell–mediated rejection (TCMR) and its association with complement component 4d (C4d) deposition. A total of 206 posttransplant pediatric patients (491 allograft liver biopsies) were available from 2000 to 2018, of which 63 patients (102 biopsies) showed evidence of TCMR and were included in the study. Of the patients, 35 (55.6%) had CLI on their initial episode of TCMR; those patients with CLI were significantly associated with the type of immunosuppression treatment (P = 0.03), severity of TCMR (P < 0.001), higher gamma-glutamyltransferase (P = 0.01), and advanced fibrosis (P = 0.03). There was a trend to shorter time interval from transplantation to presentation of CLI compared with those without CLI (P = 0.06). No difference was observed in graft or overall survival in the patients with CLI. In 20 patients with CLI, additional biopsies were available; in 45% of these patients, CLI was a persistent/recurrent finding. C4d deposition was noted in 12% of all biopsies (6 patients) with CLI. No significant correlation was noted in C4d deposition and CLI, CR, or graft/overall survival. In conclusion, CLI, although not significantly associated with worse graft survival, was significantly associated with severe TCMR and degree of fibrosis, which highlights the importance of active clinical management and follow-up for these patients.
