    Abstract:
    Acute kidney injury (AKI) is frequently observed after donation after brain death (DBD) liver transplantation (LT) and associated with impaired recipient survival and chronic kidney disease. Hepatic ischemia/reperfusion injury (IRI) is suggested to be an important factor in this process. The postreperfusion syndrome (PRS) is the first manifestation of severe hepatic IRI directly after reperfusion. We performed a retrospective study on the relation between hepatic IRI and PRS and their impact on AKI in 155 DBD LT recipients. Severity of hepatic IRI was measured by peak postoperative AST levels and PRS was defined as >30% decrease in MAP ≥1 min within 5 min after reperfusion. AKI was observed in 39% of the recipients. AKI was significantly more observed in recipients with PRS (53% vs. 32%; P = 0.013). Median peak AST level was higher in recipients with PRS (1388 vs. 771 U/l; P < 0.001). Decrease in MAP after reperfusion correlated well with both severity of AKI (P = 0.012) and hepatic IRI (P < 0.001). Multiple logistic regression identified PRS as an independent factor for postoperative AKI (OR 2.28; 95% CI 1.06-4.99; P = 0.035). In conclusion, PRS reflects severe hepatic IRI and predicts AKI after DBD LT. PRS immediately after reperfusion is an early warning sign and creates opportunities to preserve postoperative renal function.
