Abstract
Acute kidney injury (AKI) occurs frequently in patients with cirrhosis, and hepatorenal syndrome (HRS) is second most common etiology of AKI after volume responsible pre-renal etiology. AKI in these patients negatively impacts pre- and post-transplant patient survival and healthcare burden. Reduced effective blood volume with consequent reduced renal blood flow, along with systemic inflammation in patients with decompensated cirrhosis, result in susceptibility to HRS. In this article, we will review updates over the last 5 years on the changing definition with diagnostic criteria and nomenclature of AKI and HRS, data on medical treatment with vasoconstrictors, and urinary biomarkers in diagnosis of etiology of AKI. We will also discuss the significance of liver transplantation evaluation once the diagnosis of HRS is established and the post-transplant immunosuppression management. We will also review one of the challenging issues that remains among transplant-eligible patients, that of allocation of simultaneous liver kidney transplant. Finally, we will review the new implemented policy from the Organ Procurement Transplant Network on simultaneous liver kidney allocation.

Abstract
Rationale: Acute kidney injury (AKI) is a frequent complication after liver transplantation. In some patients, prompt intervention targeted at a specific etiology is of paramount importance. Presenting concerns of the patients: A 25 years old man with advanced liver cirrhosis caused by sclerosing cholangitis and autoimmune hepatitis underwent orthotopic liver transplantation. One month after surgery, severe AKI developed in conjunction with recurrent ascites and lower extremity edema. Notable clinical findings included a persistently low urinary sodium excretion, a bland urinary sediment, and an abnormally monophasic hepatic vein waveform on Doppler ultrasound. Diagnoses: Inferior vena cava stenosis. Interventions: Angioplasty with stent installation. Outcomes: Rapid improvement of renal function after stent installation. Lessons learned: The following case illustrates the importance of integrating clinical cues, ultrasound features, and laboratory findings. The combination of AKI associated with lower extremity edema, abnormal monophasic hepatic vein flow on Doppler ultrasound, and a low urinary sodium excretion after liver transplantation should evoke the possibility of inferior vena cava stenosis as the etiologic factor.

Abstract
Chronic kidney disease is a common complication after liver transplantation with an incidence ranging between 20% and 80%. Studies of renal function after liver transplantation have yielded conflicting results: the wide range in incidence rates of chronic kidney disease (CKD) following liver transplantation is related to the methods for measuring kidney function, and various criteria for defining renal dysfunction, among others. An important cause of CKD among liver transplant recipients is calcineurin inhibitor-based immunosuppression. Additional predictors of CKD post-liver transplantation include pre-transplant kidney function, peri-operative acute kidney failure, age, and hepatitis C. A recent meta-analysis of observational studies revealed that, in the subgroup of studies provided with glomerular filtration rate at baseline, the summary estimate of relative risk and 95% confidence intervals (CI) for developing chronic renal failure among liver transplant recipients with diminished renal function at transplant was 2.12 (95% CI, 1.01–4.46, p=0.047). Acute renal insufficiency is common immediately after liver transplantation, whereas the course of CKD after liver transplantation appears progressive over time. Only preliminary information exists on kidney pathological findings in recipients of liver transplants with CKD. Introduction of the Model for End-stage Liver Disease for the allocation of liver grafts has not increased the occurrence of renal dysfunction following liver transplantation. Chronic kidney disease following liver transplantation increases cardiovascular burden dramatically. The use of mycophenolic acid- or sirolimus-based immunosuppression in calcineurin-inhibitors sparing protocols is an area of intense research.

Incidence and outcomes of acute kidney injury in patients with hepatocellular carcinoma after liver transplantation. J Cancer Res Clin Oncol 2017; 143:1337-1346. [PMID: 28289896 DOI: 10.1007/s00432-017-2376-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2017] [Accepted: 02/13/2017] [Indexed: 02/07/2023]
Abstract
PURPOSE To describe the incidence and outcomes linked with acute kidney injury (AKI) after liver transplantation (LT) in hepatocellular carcinoma (HCC) patients. METHODS From January 2003 to February 2011, HCC patients undergoing LT were retrospectively enrolled. Patient with a glomerular filtration rate (GFR) <60 mL/min/1.73 m2 was excluded. AKI was defined and classified according to the AKIN criteria. RESULTS Of the 566 eligible patients, AKI was found in 109 (19.26%) patients (stage I, 66 cases; stage II, 15 cases; and stage III, 28 cases). Risk factors for AKI were the long anhepatic time (OR = 3.59, P = 0.009) and prolonged duration of systolic blood pressure (SBP) < 90 mmHg (OR = 1.07, P < 0.0001). Post-LT AKI was an independent risk factor associated with 30-day mortality (HR = 4.05, P = 0.047). Complete recovery occurred in 84 (77.06%) of all AKI episodes within 1 month after operation, while 25 patients (22.94%) suffered from prolonged AKI. Patients with prolonged AKI had a poorer 1-year survival than those with transient AKI (40 vs 86.90%; P < 0.0001). Patients with severe AKI more often developed prolonged AKI. 13 patients (52%) of the prolonged AKI progressed to chronic kidney disease (CKD) defined as eGFR <60 mL/min/1.73 m2 after 1 year post-operation. CONCLUSIONS Post-LT AKI is not an uncommon complication. Intra-operative hemodynamic instability is crucial in the development of post-LT AKI and deserves more attention. Most post-LT AKI is transient and reversible, while the prolonged form may predict a decrease survival.

Abstract
BACKGROUND AND OBJECTIVES Chronic kidney disease (CKD) has become a critical problem due to immunosuppressant related nephrotoxicity in liver transplant (LTx) recipients, especially in patients with pre-transplant risk factors. LTx recipients with uraemia and diabetes have poor prognosis even when treated with dialysis and insulin. Simultaneous pancreas and kidney transplantation (SPK) has been proven to be an effective treatment for patients with diabetic uraemia, but rarely performed in patients after LTx. Two cases of SPK after LTx were performed in our centre and we present our experience here. PATIENTS AND METHODS Two patients received LTx because of HBV related liver cirrhosis; both of them had pre-transplant diabetes mellitus (DM), which worsened after the administration of immunosuppressive drugs. These two patients suffered from CKD and developed uraemia due to diabetic nephropathy and immunosuppressive drugs induced renal toxicity years after LTx. They relied on dialysis and insulin injection. SPK were performed years after LTx and the clinical data was retrospectively analyzed. RESULTS SPK was successfully performed in these two patients. Pancreatic fluid drainage was achieved via a side-to-side duodenojejunostomy into the proximal jejunum. No serious surgical complications, including pancreatitis or pancreatic fistula were observed postoperatively. In both cases, kidney and pancreatic grafts were functioning well as evidenced by euglycemia without the need for insulin injections and normal serum-creatinine level 7days after the operation. One of the patients presented with renal graft impairment 1week after the operation. FK506 was tapered and rapamycin was used when the renal graft biopsy indicated drug toxicity. The patient's kidney graft function recovered gradually after the adjustment. Both patients have good function of liver, kidney and pancreas grafts during a 60-month and 30-month period of follow up. CONCLUSIONS SPK could serve as an effective option for patients with diabetes and uremia after LTx. Perioperative management, especially the immunosuppressive strategy is crucial to improve the outcome of this procedure.

Risk factors for acute renal injury in living donor liver transplantation: evaluation of the RIFLE criteria. Transpl Int 2014; 26:842-52.

Abstract
Acute renal injury (ARI) is a serious complication after liver transplantation. This study investigated the usefulness of the RIFLE criteria in living donor liver transplantation (LDLT) and the prognostic impact of ARI after LDLT. We analyzed 200 consecutive adult LDLT patients, categorized as risk (R), injury (I), or failure (F), according to the RIFLE criteria. ARI occurred in 60.5% of patients: R-class, 23.5%; I-class, 21%; and F-class, 16%. Four patients in Group-A (normal renal function and R-class) and 26 patients in Group-B (severe ARI: I- and F-class) required renal replacement therapy (P < 0.001). Mild ARI did not affect postoperative prognosis regarding hospital mortality rate in Group A (3.2%), which was superior to that in Group B (15.8%; P = 0.0015). Fourteen patients in Group B developed chronic kidney disease (KDIGO stage 3/4). The 1-, 5- and 10-year survival rates were 96.7%, 90.6%, and 88.1% for Group A and 71.1%, 65.9%, and 59.3% for Group B, respectively (P < 0.0001). Multivariate analysis revealed risk factors for severe ARI as MELD ≥ 20 [odds ratio (OR) 2.9], small-for-size graft (GW/RBW <0.7%; OR 3.1), blood loss/body weight >55 ml/kg (OR 3.7), overexposure to calcineurin inhibitor (OR 2.5), and preoperative diabetes mellitus (OR 3.2). The RIFLE criteria offer a useful predictive tool after LDLT. Severe ARI, defined beyond class-I, could have negative prognostic impact in the acute and late postoperative phases. Perioperative treatment strategies should be designed and balanced based on the risk factors for the further improvement of transplant prognosis.

Abstract
Posttransplant immunosuppression with calcineurin inhibitors (CNIs) is associated with impaired renal function, while mTor inhibitors such as everolimus may provide a renal-sparing alternative. In this randomized 1-year study in patients with liver transplantation (LTx), we sought to assess the effects of everolimus on glomerular filtration rate (GFR) after conversion from CNIs compared to continued CNI treatment. Eligible study patients received basiliximab induction, CNI with/without corticosteroids for 4 weeks post-LTx, and were then randomized (if GFR > 50 mL/min) to continued CNIs (N = 102) or subsequent conversion to EVR (N = 101). Mean calculated GFR 11 months postrandomization (ITT population) revealed no significant difference between treatments using the Cockcroft-Gault formula (-2.9 mL/min in favor of EVR, 95%-CI: [-10.659; 4.814], p = 0.46), whereas use of the MDRD formula showed superiority for EVR (-7.8 mL/min, 95%-CI: [-14.366; -1.191], p = 0.021). Rates of mortality (EVR: 4.2% vs. CNI: 4.1%), biopsy-proven acute rejection (17.7% vs. 15.3%), and efficacy failure (20.8% vs. 20.4%) were similar. Infections, leukocytopenia, hyperlipidemia and treatment discontinuations occurred more frequently in the EVR group. No hepatic artery thrombosis and no excess of wound healing impairment were noted. Conversion from CNI-based to EVR-based immunosuppression proved to be a safe alternative post-LTx that deserves further investigation in terms of nephroprotection.

Abstract
PURPOSE OF REVIEW Acute and chronic kidney injury following orthotopic liver transplantation (OLT) is associated with increased morbidity and mortality. With the increasing longevity of liver transplant recipients, chronic kidney disease (CKD) has become an increasingly prevalent complication among long-term survivors. This article provides an overview of the literature on suggested risk factors for acute and CKD following OLT and a discussion of an approach to their medical management. RECENT FINDINGS In OLT candidates with pretransplant renal dysfunction, the use of interleukin-2 receptor blockers or antithymocyte globulin induction therapy in conjunction with delayed introduction of calcineurin inhibitors may preserve early renal function. In long-term stable OLT recipients with established calcineurin inhibitor nephrotoxicity, calcineurin inhibitor minimization or withdrawal protocols may halt or ameliorate renal dysfunction without compromising patient and graft survival. However, large-scale, multicenter, randomized controlled trials are still needed. SUMMARY The occurrence of acute kidney injury is common immediately after OLT, whereas the incidence of CKD and end-stage renal disease increases with time. Identifying patients at risk for acute kidney injury and CKD following OLT and early implementation of measures to preserve, halt, or ameliorate the progression of renal dysfunction should be an integral part in the management of OLT recipients.

Abstract
The purpose of this study is to review the clinical experience with sirolimus immunosuppression in liver transplant patients with calcineurin inhibitor-induced chronic renal insufficiency. The study design is a case-control retrospective series. Fifty-seven liver transplant patients with renal insufficiency that were started on sirolimus at greater than 90 days postoperatively and treated for more than 90 days were identified. A control group of 57 patients maintained on low-dose calcineurin inhibitors, matched for gender, year of transplant, and baseline creatinine clearance, was also identified. There were no significant differences in the absolute creatinine clearance values between the sirolimus and control groups from 6 months before sirolimus conversion to 12 months after sirolimus conversion. Patients exposed to calcineurin inhibitors for more than 5 years or those with an initial creatinine clearance of less than 30 mL/minute who were converted to sirolimus did worse than control patients maintained on low-dose calcineurin inhibitors. Progression to renal replacement therapy, episodes of acute and chronic rejection, and death were similar between the sirolimus and control groups. The overall prevalence of side effects was significantly higher in the sirolimus group compared with the control group, although these were generally tolerable in most patients. In conclusion, this study suggests that conversion to sirolimus in liver transplant patients with chronic renal insufficiency is associated with stabilization of renal function but confers no additional benefit to low-dose calcineurin inhibitor regimens and may in fact be disadvantageous in patients with a creatinine clearance of less than 30 mL/minute.

Abstract
BACKGROUND Survival 10 years after orthotopic liver transplantation now approaches 65%. Consequently, community doctors must manage the metabolic and neoplastic complications of orthotopic liver transplantation in an ageing population. AIMS To review common sources of morbidity and mortality in long-term orthotopic liver transplantation recipients, and to make evidence-based recommendations regarding their management. METHODS Pertinent studies and reviews were identified by literature search through PubMed. Where evidence-based recommendations could not be gleaned from the literature, expert opinion was obtained from syllabi of national meetings. RESULTS The two most common causes of morbidity and mortality in orthotopic liver transplantation recipients are atherosclerotic vascular disease and de novo malignancy. The pathogenesis of many complications begins before orthotopic liver transplantation, and many are potentially modifiable. Most complications, however, can be directly ascribed to immunosuppressive agents. Despite improvements in our understanding of the pathogenesis and epidemiology of the metabolic and neoplastic complications of orthotopic liver transplantation, remarkably few randomized-controlled studies exist to define their optimal management. CONCLUSIONS Orthotopic liver transplantation recipients experience and succumb to the same afflictions of old age as non-transplant patients, but with greater frequency and at an earlier age. Most recommendations regarding surveillance for, and treatment of, medical complications of orthotopic liver transplantation remain based upon expert opinion rather than evidence-based medicine.

Abstract
BACKGROUND Renal dysfunction is common after liver transplantation (LT). The aim of our study was to assess the prevalence of renal dysfunction 5 yr after LT and to identify risk factors for the development of this complication. PATIENTS AND METHODS A total of 134 adult patients underwent LT from 1987 to 1998 and 74.6% of them were alive 5 yr after. Pre-LT, 1 and 5 yr post-LT renal function were calculated by Cockroft and modification of diet in renal disease (MDRD) formula. Since 1987 glomerular filtration rate (GFR) has been measured by radiolabeled tracers clearance (RTC). Risk factors for GFR < 50 mL/min were analyzed using a multivariate logistic regression model. RESULTS Mean pre-LT GFR was 79 and 85 mL/min with Cockroft and MDRD respectively; 11% of the patients had a GFR <or= 50 mL/min. 5 yr after LT, mean GFR was 63, 61 and 70 mL/min with MDRD, Cockroft and RTC respectively, GFR decreased by 26%, and 25% of the patients had a GFR < 50 mL/min. Independent risk factors associated with impaired renal function were: trough levels of cyclosporin A (CyA) >or= 150 microg/L or tacrolimus (FK) >or= 10 microg/L at 1 yr and CyA >or= 100 microg/L or FK >or= 8 microg/L at 5 yr. CONCLUSION 5 yr after LT, patients have lost 26% of their initial GFR and 25% of them have a GFR < 50 mL/min. This complication is predicted by high levels of calcineurin inhibitors (CNI). Therefore CNI levels should be reduced as low as possible and use of alternative drugs should be considered.

Abstract
Although renal dysfunction is common after liver transplantation, postoperative renal function after split liver transplantation (SLT) has not been well studied. Renal function immediately after surgery was analyzed retrospectively in 16 patients that received a SLT (SLT group). The results were compared with corresponding data from 31 matched patients that received a full-size liver transplant (FSLT group) during the same period. Serum creatinine (SCr) was measured before surgery, and, after transplantation, daily during the first week and at days 14, 21, and 28. Renal dysfunction (RD) was defined as the requirement for renal replacement therapy (RRT) or a 100% increase in SCr if the basal value had been <1.0 mg/dL or a 50% increase in SCr if the basal value had been >1.0 mg/dL. SCr had to be at least 1.5 mg/dL for a diagnosis of RD to be considered. The classification of RD was: mild, SCr 1.5-2.4 mg/dL; moderate, SCr 2.5-4.0 mg/dL; or severe, SCr >4.0 mg/dL (the requirement for RRT). Both donor and recipient age and cold ischemia time were lower in the SLT group than in the FSLT group (P < 0.05). Length of surgery was longer in the SLT group (P < 0.05). There were no significant differences between groups with respect to Model for End-Stage Liver Disease scores, the need for transfusions, the length of admission to the intensive care unit (ICU), survival rate, individual severity index, or sepsis-related organ failure assessment scores at the time of diagnosing RD. Immunosuppression regimens were similar in both groups. RD developed in 82% of SLT patients, but in only 58% of FSLT patients (P = not significant [NS]). Among SLT patients, RD (23.0% mild, 15.5% moderate, and 61.5% severe) was more severe (P = 0.007) than in FSLT patients (63.1% mild, 15.8% moderate, and 24.1% severe). The requirement for RRT in the SLT group (43.7%) was significantly greater (P < 0.05) than that in the FSLT group (12.9%). This finding may be due to the different incidence of sepsis in the 2 groups (SLT 37.5% vs. FSLT 9.7%; P < 0.05). In conclusion, although the number of patients studied was small, our data suggest a higher incidence of RD and a greater requirement for RRT in patients that receive a split liver graft than in those that receive a full size liver graft.

Abstract
Chronic renal failure (CRF) is increasingly prevalent in solid-organ-transplant patients. This is in part related to the long-term use of calcineurin inhibitor (CNI) agents. However, in orthotopic liver-transplant (OLT) patients, the effects of superimposed hepatitis C virus (HCV)-related renal lesions could also be a factor. The aim of this cohort study (February 2000 to September, 2003) was to identify the predictive factors at one year post-transplantation for CRF in OLT patients associated with induction therapies. CRF was defined as having a creatinine clearance (CC) lower than 60 mL/min. Of the 97 transplants performed during that period, 72 were still functioning after one year. Of these, 33 patients (45.8%) had CRF. In univariate analysis, the predicting factors for CRF were recipient sex (female), initial liver disease (HCV-related cirrhosis), pre-transplant CC (<80 mL/mn), and post-transplant serum creatinine >130 micromol/L at day 3 and months (M) 1, 3, and 6. In multivariate analysis, the independent predictive factors for CRF included female sex [OR: 11.5 (2.3-58.3); p = 0.003], HCV infection [OR: 5.01 (1.1-22.7); p = 0.03], pre-OLT CC <80 mL/mn [OR: 5.4 (1.2-23.7); p = 0.025], and serum creatinine at M6 greater than 130 micromol/L [OR: 19.6 (3.7-102.5); p = 0.0004]. Among all of the predictive factors for post-OLT CRF, only one is modifiable: post-transplant serum creatinine, which could be, to some extent, related to the long-term use of CNIs.

Abstract
1. Pretransplant kidney function is an important predictor of posttransplant kidney function. 2. Chronic kidney disease is present in 20% of liver transplant recipients by 5 years. 3. Kidney function is impacted by pretransplant management of the consequences of the hepatorenal syndrome. 4. The use of calcineurin inhibitor (CNI)-based immunosuppression is an important factor in the development of chronic kidney disease, and the use of mycophenolic acid- or sirolimus-based immunosuppression with reduced-dose CNI may be of benefit.

Abstract
Renal dysfunction (RD) is a frequent complication after orthotopic liver transplantation (OLT), and it has an unfavorable effect on the prognosis of OLT patients. The purpose of our study was to identify possible risk factors for RD and its impact on survival. The possible relations of pre-, peri-, and postoperative variables to early-onset renal dysfunction (ED) (within the 1st 3 months), late-onset renal dysfunction (LD) (between 3 and 6 months), and chronic renal dysfunction (CRD) (beyond 6 months) was analyzed. We studied 245 liver transplants in 241 patients. RD was found in 64.1% of these patients, and 69% of the patients with RD recovered. LD was found in 16.7% of the transplant patients. In the multivariate analysis, baseline serum creatinine, perioperative volume of transfused bank-red blood cells, Acute Physiology and Chronic Health Evaluation (APACHE) II score at intensive care unit (ICU) admission, and infection were associated with the development of RD. Overall mortality was 27.8% and for the RD group, it was 33.5%. LD, but not ED, was related to lower survival (together with graft dysfunction and APACHE II score at ICU admission). In conclusion, ED is frequent alter OLT and is related to preexisting RD, the volume of transfused bank--red blood cells during surgery, higher APACHE II score at ICU admission, and infection. In general, the prognosis for ED is good, in contrast with that of LD, which is associated with diminished survival.
