Journal : Transplantation Year : 2015 / Month : September Volume : 99 Pages: 1756–1764 DOI: 10.1097/TP.0000000000000820 ABSTRACT Kidney injury is associated with increased morbidity and mortality in liver transplant recipients. Since the introduction of the model for end-stage liver disease for the allocation of organs for liver transplantation in 2002, the heavy weighting of serum creatinine in the model for end-stage liver disease score has significantly increased the incidence of renal dysfunction seen among patients undergoing liver transplantation. As a result, the frequency of simultaneous liver-kidney (SLK) transplantation compared to liver transplantation alone (LTA) has also increased. The decision to perform SLK rather than LTA is an important one because the benefits to the liver transplant recipient receiving a kidney transplant must be balanced with the benefits of using that organ for a patient with end-stage renal disease. However, predicting whether or not a patient with liver failure has reversible kidney disease, and therefore does not also need a kidney transplant, is difficult. The severity and duration of pretransplant renal dysfunction, hepatitis c, diabetes, and other risk factors for kidney disease are associated with an increased risk of posttransplant end-stage renal disease. However, there are currently no clinical findings that accurately predict renal recovery post liver transplant. As a result, the rate of SLK versus LTA differs significantly between transplant centers. To increase consistency across centers, multiple guidelines have been proposed to guide the decision between SLK and LTA, but their poor predictive value has limited their uniform adoption. Nevertheless, adoption of uniform rules for the allocation of kidneys would reduce the variability between centers in rates of SLK transplant. COMMENTS Renal dysfunction, both before and after liver transplantation, is a major complicating factor associated with increased morbidity, mortality, and cost. The prevalence of CKD in liver transplant recipients ranges from 20% to 80%. The risk of developing end-stage renal disease (ESRD) requiring renal replacement therapy (RRT) ranges from 2% to 5% per year after liver transplant alone (LTA). The decision to perform SLK rather than LTA is important, because the benefits to the patient with liver disease of receiving a kidney transplant must be balanced with the downside of not being able to use that organ for a patient with ESRD. The critical question to answer is which patients with pretransplant renal dysfunction or failure have reversible versus irreversible renal dysfunction, because those with reversible dysfunction should receive a LTA, whereas irreversible, severe dysfunction is the indication for SLK. In this review, the authors gather existing data on predicting whether or not a patient with liver failure has reversible kidney disease, as well as arguments for and against erring on the side of performing SLK versus LTA transplants. Acute kidney injury in advanced liver disease is common but likely underestimated because of falsely low serum creatinine levels. The incidence of AKI in liver disease is poorly defined. After liver transplantation, AKI is also common. Many intraoperative factors may contribute to the development of AKI including intraoperative hemodynamic instability requiring high-dose vasopressors, severe postreperfusion syndrome, or the need for either aortic or inferior vena cava cross-clamping. Ten years after liver transplantation, approximately 18% of patients will develop ESRD, and many of them will be considered for kidney transplantation. The rate of development and progression of posttransplantation CKD can potentially be reduced with careful preoperative and perioperative care. Well balanced guidelines concerning the dual liver and kidney transplantation are presently missing. Pr. Jacques CHANARD Professor of Nephrology
