Abstract

In the past decades liver transplantation (LT) has become the treatment of choice for patients with end-stage liver disease (ESLD). The chronic shortage of cadaveric organs for transplantation led to the utilization of a greater number of marginal donors such as older donors or donors after circulatory death (DCD).
The improved survival of transplanted patients has increased the frequency of long-term complications, in particular chronic kidney disease (CKD). Acute kidney injury (AKI) post-LT has been recently recognized as an important risk factor for the occurrence of de novo CKD in the long-term outcome. The onset of AKI post- LT is multifactorial, with pre-LT risk factors involved, including higher Model for ESLD score, more severe ESLD and pre-existing renal dysfunction, either with intra-operative conditions, in particular ischaemia reperfusion injury responsible for post-reperfusion syndrome (PRS) that can influence recipient’s morbidity
and mortality. Post-reperfusion syndrome-induced AKI (PRS-induced AKI) is an important complication post-LT that characterizes kidney involvement caused
by PRS with mechanisms not clearly understood and implication on graft and patient survival. Since pre-LT risk factors may influence intra-operative events
responsible for PRS-induced AKI, we aim to consider all the relevant aspects involved in PRS-induced AKI in the setting of LT and to identify all studies that better clarified the specific mechanisms linking PRS and AKI. A PubMed search was conducted using the terms LT AND AKI; LT AND PRS; acute kidney injury AND PRS; acute kidney injury AND DCD AND LT. Five hundred seventy four articles were retrieved on PubMed search. Results were limited to title/abstract of English-language articles published between 2000 and 2015. Twenty three
studies were identified that specifically evaluated incidence, risk factors and outcome for patients developing PRS-induced AKI in LT. In order to identify
intra-operative risk factors/mechanisms specifically involved in PRS-induced AKI, avoiding confounding factors, we have limited our study to “acute kidney
injury AND DCD AND LT”. Accordingly, three out of five studies were selected for our purpose.
