Abstract
PURPOSES End-stage liver and kidney disease is an indication for simultaneous liver and kidney transplantation. However, in countries where deceased donor transplantation is not well established, living donor liver transplantation (LDLT) is a realistic option for patients on hemodialysis (HD). We investigated the outcomes of LDLT for patients on HD. METHODS We conducted a retrospective multicenter survey of patients on chronic HD who underwent LDLT in East Asian countries. The characteristics of donors and recipients and the short and long-term outcomes were analyzed. RESULTS Between 2001 and 2021, 45 patients on HD underwent LDLT and 11 of these patients also underwent kidney transplantation (KT). The overall survival rate at 5 years of the 34 patients who underwent only LDLT was 44.5%. Multivariate analysis identified a low graft recipient weight ratio (< 1%) (p = 0.048) and long HD duration (≥ 10 years) (p = 0.046) as independent predictors of poor overall survival. The major complication was posttransplant bleeding, which occurred in12 patients (35%). CONCLUSION It is important to establish the indications for LDLT, taking into consideration graft size and HD duration in candidate patients on HD.

Abstract
Chronic kidney disease among liver transplant recipients is common and associated with an increased mortality risk. Several risk factors and causes for the development of chronic kidney disease have been identified. They can be divided into perioperative factors, such as unresolved acute kidney injury; donor-related factors, such as the use of extended criteria liver allografts; and recipient-related factors, such as the use of calcineurin inhibitors and the presence of metabolic syndrome, diabetes, and obesity. There is a bimodal progression, more prominent during the initial post-transplant months, followed by a gradual but progressive decline over the subsequent years. Management strategies to prevent and treat chronic kidney disease in the general population can be reasonably applied to the liver transplant population and include addressing comorbidities such as hypertension and diabetes. Strategies to minimize or withdraw calcineurin inhibitors from the immunosuppressive regimen can slow progression of kidney dysfunction. Patients with advanced chronic kidney disease should be considered for kidney transplantation due to its survival advantage. Allocation policy in the United States confers safety-net allocation priority for liver transplant recipients who develop advanced chronic kidney disease within the first year of liver transplantation.

Abstract
BACKGROUND Polycystic liver disease (PLD) is characterized by the progressive development of polycystic lesions in the kidney and the liver, possibly resulting in dual organ failure. We indicated living donor liver transplantation (LDLT) for a patient with end-stage liver and kidney disease (ELKD) due to PLD on uncomplicated chronic hemodialysis. CASE PRESENTATION A 63-year-old man with ELKD and uncontrolled massive ascites due to PLD and hepatitis B on uncomplicated chronic hemodialysis was referred to us with a single possible 47-year-old female living donor. Because of the necessity of right lobe liver procurement from this small middle-aged donor and uncomplicated hemodialysis on this recipient, we considered LDLT, rather than dual organ transplantation, could be the most well-balanced option to save the life of this recipient with acceptable risk limits for this donor. A right lobe graft with 0.91 for graft recipient weight ratio was implanted with an uneventful operative procedure under intra- and postoperative continuous hemodiafiltration. The recipient was rescheduled on routine hemodialysis on day 6 after transplantation and recovered with a gradual decrease in ascites output. He was discharged on day 56. He continues to have a very good liver function and quality of life without ascites and uncomplicated routine hemodialysis 1 year after transplantation. The living donor was discharged 3 weeks after surgery and is also doing well. CONCLUSION Although combined liver-kidney transplantation from a deceased donor could be the best option for ELKD due to PLD, LDLT can also be an acceptable option for ELKD with uncomplicated hemodialysis, considering the double equipoise theory for both lifesaving of the recipient and acceptable donor risk.

Abstract
One third of cirrhotic patients present impaired kidney function. It has multifactorial causes and has a harmful effect on patients' morbi-mortality before and after liver transplant. Kidney function does not improve in all patients after liver transplantation and liver-transplant recipients are at high risk of developing chronic kidney disease. Causes for renal dysfunction can be divided in three groups: preoperative, peroperative and postoperative factors. To date, there is no consensus for the modality of evaluation the risk for chronic kidney disease after liver transplantation, and for its prevention. In the present review, we describe the outcome of kidney function after liver transplantation, and the prognostic factors of chronic kidney disease to determine a risk stratification for each patient. Furthermore, we discuss therapeutic options to prevent kidney dysfunction in this setting, and highlight the indications of combined liver-kidney transplantation.

Abstract
The incidence of kidney dysfunction has increased in liver transplant and heart transplant candidates, reflecting a changing patient population and allocation policies that prioritize the most urgent candidates. A higher burden of pretransplant kidney dysfunction has resulted in a substantial rise in the utilization of multiorgan transplantation (MOT). Owing to a shortage of available deceased donor kidneys, the increased use of MOT has the potential to disadvantage kidney-alone transplant candidates, as current allocation policies generally provide priority for MOT candidates above all kidney-alone transplant candidates. In this review, the implications of kidney disease in liver transplant and heart transplant candidates is reviewed, and current policies used to allocate organs are discussed. Important ethical considerations pertaining to MOT allocation are examined, and future policy modifications that may improve both equity and utility in MOT policy are considered.

Abstract
One-third of patients with cirrhosis present kidney failure (AKI and CKD). It has multifactorial causes and a harmful effect on morbidity and mortality before and after liver transplantation. Kidney function does not improve in all patients after liver transplantation, and liver transplant recipients are at a high risk of developing chronic kidney disease. The causes of renal dysfunction can be divided into three groups: pre-operative, perioperative and post-operative factors. To date, there is no consensus on the modality to evaluate the risk of chronic kidney disease after liver transplantation, or for its prevention. In this narrative review, we describe the outcome of kidney function after liver transplantation, and the prognostic factors of chronic kidney disease in order to establish a risk categorization for each patient. Furthermore, we discuss therapeutic options to prevent kidney dysfunction in this context, and highlight the indications of combined liver–kidney transplantation.

Abstract
Kidney-alone transplant (KAT) candidates may be disadvantaged by the allocation priority given to multi-organ transplant (MOT) candidates. This study identified potential KAT candidates not receiving a given kidney offer due to its allocation for MOT. Using the Organ Procurement and Transplant Network (OPTN) database, we identified deceased donors from 2002 to 2017 who had one kidney allocated for MOT and the other kidney allocated for KAT or simultaneous pancreas-kidney transplant (SPK) (n = 7,378). Potential transplant recipient data were used to identify the "next-sequential KAT candidate" who would have received a given kidney offer had it not been allocated to a higher prioritized MOT candidate. In this analysis, next-sequential KAT candidates were younger (p < .001), more likely to be racial/ethnic minorities (p < .001), and more highly sensitized than MOT recipients (p < .001). A total of 2,113 (28.6%) next-sequential KAT candidates subsequently either died or were removed from the waiting list without receiving a transplant. In a multivariable model, despite adjacent position on the kidney match-run, mortality risk was significantly higher for next-sequential KAT candidates compared to KAT/SPK recipients (hazard ratio 1.55, 95% confidence interval 1.44, 1.66). These results highlight implications of MOT allocation prioritization, and potential consequences to KAT candidates prioritized below MOT candidates.

Abstract
During the past few decades, liver transplant has developed from a high-mortality procedure to an almost routine procedure with good survival outcomes. The development of living donor liver transplant has increased the availability of liver grafts, and the scope of indications for liver transplant has been expanding ever since. The aim of this review is to provide an overview of such an expansion of scope. Various criteria have been proposed to expand the eligibility of patients with hepatocellular carcinoma exceeding the Milan criteria for liver transplant. Furthermore, liver transplant is increasingly performed as a treatment modality for cholangiocarcinoma, neuroendocrine liver metastasis and colorectal liver metastasis. The number of elderly patients receiving liver transplant is on the rise. Combined organ transplantation has also been adopted to treat patients with multiple organ failure. Going forward, further development of preoperative noninvasive predictors in tumor, patient and even donor factors is needed to identify patients at risk of poor outcomes and hence optimize patient management.

Abstract
AIM Rates of simultaneous liver and kidney transplantation (SLKT) have increased, but indications for SLKT remain poorly defined. Additional data are needed to determine which patients benefit from SLKT to best direct use of scarce donor kidneys. METHODS Data were extracted from the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) database for all SLKT performed until the end of 2017. Patients were divided by pretransplant dialysis status into no dialysis before SLKT (preemptive kidney transplant) and any dialysis before SLKT (nonpreemptive). Baseline characteristics and outcomes were compared. RESULTS Between 1989 and 2017, inclusive, 84 SLKT procedures were performed in Australia, of which 24% were preemptive. Preemptive and nonpreemptive SLKT recipients did not significantly differ in age (P = .267), sex (P = .526), or ethnicity (P = .870). Over a median follow-up time of 4.5 years, preemptively transplanted patients had a statistically equivalent risk of kidney graft failure (hazard ratio (HR) 1.83, 95% confidence interval [CI]: 0.36-12.86, P = .474) and all-cause mortality (HR 1.69, 95% CI: 0.51-5.6, P = .226) compared to nonpreemptive patients. Overall, 1- and 5-year survival rates for all SLKTs were 92% (95% CI: 86-96) and 60% (95% CI: 45-75), respectively. CONCLUSION Kidney graft and overall patient survival were similar between patients with preemptive kidney transplant and those who were dialysis dependent.

Abstract
Background Acute kidney injury (AKI) is a common complication in patients undergoing liver transplant (LT) and is associated with high morbidity and mortality. We aim to evaluate the pattern of urine and plasma neutrophil gelatinase-associated lipocalin (NGAL) elevation during the perioperative period of LT and to assess it as a prognostic marker for AKI progression, need for dialysis and mortality. Methods We assessed NGAL levels before induction of anesthesia, after portal reperfusion and at 6, 18, 24, and 48 h after surgery. Patients were monitored daily during the first week after LT. Results Of 100 enrolled patients undergoing liver transplant, 59 developed severe AKI based on the KDIGO serum creatinine (sCr) criterion; 34 were dialysed, and 21 died within 60 days after LT. Applying a cut-off value of 136 ng/ml, UNGAL values 6 h after surgery was a good predictor of AKI development within 7 days after surgery, having a positive predictive value (PPV) of 80% with an AUC of 0.76 (95% CI 0.67–0.86). PNGAL at 18 h after LT was also a good predictor of AKI in the first week, having a PPV of 81% and AUC of 0.74 (95% CI 0.60–0.88). Based on PNGAL and UNGAL cut-off criteria levels, time to AKI diagnosis was 28 and 23 h earlier than by sCr, respectively. The best times to assess the need for dialysis were 18 h after LT by PNGAL and 06 h after LT by UNGAL. Conclusion In conclusion, the plasma and urine NGAL elevation pattern in the perioperative period of the liver transplant can predict AKI diagnosis earlier. UNGAL was an early independent predictor of AKI development and need for dialysis. Further studies are needed to assess whether the clinical use of biomarkers can improve patient outcomes. Trial registration Registered at Clinical Trials (clinicaltrials.gov) in March 24th, 2014 by title “Acute Kidney Injury Biomarkers: Diagnosis and Application in Pre-operative Period of Liver Transplantation (AKIB)” and identifier NCT02095431, retrospectively registered.

Outcomes of Liver Transplantation in Patients on Renal Replacement Therapy: Considerations for Simultaneous Liver Kidney Transplantation Versus Safety Net. Transplant Direct 2019; 5:e490.

Abstract
As the liver transplant (LT) waiting list continues to outpace organ availability, many patients require renal replacement therapy (RRT) before LT. It is unclear which patients will benefit from simultaneous liver kidney (SLK) transplant as opposed to awaiting a Safety Net kidney transplant (KT) post-LT. Methods In this study, a retrospective analysis of the United Network for Organ Sharing dataset was performed to identify risk factors associated with poor outcome for patients on RRT before LT who were listed for SLK and received either SLK vs LT alone (LTA). Results Between January 2003 and December 2016, 8971 adult LT recipients were on RRT at the time of LT. 5359 were listed for and received LTA (Group 1). Of 3612 patients listed for SLK, 3414 (38.1%) received SLK (Group 2) and 198 (2.2%) received LTA (Group 3). Overall, Group 3 had lower graft and patient survival post-LT when compared with Groups 1 and 2 (P < 0.001). Serum creatinine at 1 year post-LT and cumulative incidence for KT at 3 years post-LT were higher for Group 3 (P < 0.001). On multivariate analysis, pre-LT diabetes (P = 0.002), Model of End-Stage Liver Disease score (P = 0.01), and donor kidney donor profile index (P = 0.025) were significant in Group 2. Recipient age >60 (P < 0.001) and RRT pre-LT (>90 days; P = 0.001) were associated with lower patient survival in Group 3. Conclusions Among LT recipients on RRT before LT who were listed for SLK, RRT >90 days, and age >60 were associated with poor outcome following LTA. This suggests that programs should carefully weigh the decision to proceed with LTA vs waiting for SLK in this patient population. Future access to Safety Net KT will be an important consideration for these patients moving forward.

Combined liver-kidney transplantation versus liver transplant alone based on KDIGO stratification of estimated glomerular filtration rate: data from the United Kingdom Transplant registry - a retrospective cohort study. Transpl Int 2019; 32:918-932. [PMID: 30793378 DOI: 10.1111/tri.13413] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2018] [Revised: 10/29/2018] [Accepted: 02/18/2019] [Indexed: 12/22/2022]
Abstract
Patient selection for combined liver-kidney transplantation (CLKT) is a current issue on the background of organ shortage. This study aimed to compare outcomes and post-transplant renal function for patients receiving CLKT and liver transplantation alone (LTA) based on native renal function using estimated glomerular filtration rate (eGFR) stratification. Using the UK National transplant database (NHSBT) 6035 patients receiving a LTA (N = 5912; 98%) or CLKT (N = 123; 2%) [2001-2013] were analysed, and stratified by KDIGO stages of eGFR at transplant (eGFR group-strata). There was no difference in patient/graft survival between LTA and CLKT in eGFR group-strata (P > 0.05). Of 377 patients undergoing renal replacement therapy (RRT) at time of transplantation, 305 (81%) and 72 (19%) patients received LTA and CLKT respectively. A significantly greater proportion of CLKT patients had severe end-stage renal disease (eGFR < 30 ml/min/1.73 m2 ) at 1 year post-transplant compared to LTA (9.5% vs. 5.7%, P = 0.001). Patient and graft survival benefit for patients on RRT at transplantation was favouring CLKT versus LTA (P = 0.038 and P = 0.018, respectively) but the renal function of the long-term survivors was not superior following CLKT. The data does not support CLKT approach based on eGFR alone, and the advantage of CLKT appear to benefit only those who are on established RRT at the time of transplant.

Abstract
BACKGROUND The Organ Procurement and Transplantation Network has implemented medical criteria to determine which candidates are most appropriate for simultaneous liver-kidney (SLK) transplantation in comparison to liver-alone transplantation. We investigated prepolicy center-level variation among SLK listing practice, in light of such criteria. METHODS We identified 4736 SLK-eligible candidates after Share-35 in the United States. We calculated the proportion of candidates at each center who were listed for SLK transplantation within 6 months of eligibility. Multilevel logistic regression and parametric survival model was used to estimate the center-specific probability of SLK listing, adjusting for patient and center-level characteristics. RESULTS Among 4736 SLK-eligible candidates, 64.8% were listed for SLK within 6 months of eligibility. However, the percentage of SLK listing ranged from 0% to 100% across centers. African American race, male sex, transplant history, diabetes, and hypertension were associated with a higher likelihood of SLK listing. Conversely, older age was associated with a lower likelihood of SLK listing. After adjusting for candidate characteristics, the percentage of SLK listing still ranged from 3.8% to 80.2% across centers; this wide variation persisted even after further adjusting for center-level characteristics. CONCLUSIONS There was significant prepolicy center-level variation in SLK listing for SLK-eligible candidates. Implementation of standardized SLK listing practices may reduce center-level variation and equalize access for SLK candidates across the United States.

Abstract
BACKGROUND & AIMS Pretransplant renal failure is commonly reported to be a poor prognostic indicator affecting survival after liver transplantation (LT). However, whether the impact of renal failure on patient outcome varies according to the aetiology of the underlying liver disease is largely unknown. METHODS We investigated the association between renal failure at the time of LT and patient outcome in patients with alcoholic liver disease (ALD) (n = 6920), non-alcoholic steatohepatitis (NASH) (n = 2956) and hepatitis C (HCV) (n = 14 922) using the United Network for Organ Sharing (UNOS) database between February 2002 and December 2013. A total of 24 798 transplant recipients were included. RESULTS The presence of renal failure was more frequently seen in patients with ALD (23.95%) and NASH (23.27%) compared to patients with HCV (19.38%) (P < 0.001). In multivariate analysis, renal failure was an independent predictor of poor survival. Renal failure showed detrimental effect on patient survival in the overall series (HR = 1.466, P < 0.0001). Importantly, the impact of renal failure was less marked in patients with ALD (HR = 1.31, P < 0.0001) than in patients with NASH (HR = 1.73, P < 0.0001) or HCV (HR = 1.52, P < 0.0001). Despite a higher model for end-stage liver disease (MELD) score at the time of LT, ALD patients with renal failure had better long-term prognosis than non-ALD patients. CONCLUSIONS Renal failure at the time of LT conferred a lower patient and graft survival post-LT. However, renal failure has less impact on the outcome of patients with ALD than that of patients with non-alcoholic liver disease after LT.

Outcomes of Living Donor Liver Transplantation Alone for Patients on Maintenance Renal Replacement Therapy in Japan: Results of a Nationwide Survey. Transplant Direct 2016; 2:e74. [PMID: 27500264 PMCID: PMC4946519 DOI: 10.1097/txd.0000000000000587] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2016] [Accepted: 03/23/2016] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Because simultaneous liver and kidney transplantation has been limited as a standard practice because of a severe shortage of deceased donors in Japan, living donor (LD) liver transplantation alone (LTA) is indicated in most recipients with maintenance renal replacement therapy (MRRT). METHODS A retrospective nationwide survey of LD LTA was performed for liver transplant patients on MRRT. The characteristics of donors and recipients, postoperative complications, survival rate, and causes of death were analyzed. RESULTS In the adult cases (n = 28), the overall survival rate at 1 year and 5 years were 66.1% and 57.3%, respectively. When compared with those adults without MRRT (n = 237), it was significantly worse. In the 7 pediatric cases, the overall survival rate at 1 and 5 years were both 83.3%. Three adult recipients died of nonaneurysm cerebral hemorrhage after 1 year and 1 adult recipient died of acute heart failure after 7 months. In adult recipients with MRRT, graft weight versus standard liver volume, and duration and blood loss in LTA surgery were associated with poor outcomes after LD LTA. Multivariate analysis revealed that MRRT was highest hazard ratio on patient survival after LD LTA. CONCLUSIONS Early post-LD LTA mortality was higher in patients with MRRT than in those without MRRT with characteristic causes. Smaller grafts for size and a complicated surgery were associated with poor outcome after LD LTA. Thus, LD LTA in adult patients on MRRT should be carefully treated with meticulous postoperative management and follow-up.

Abstract
Introduction The survival benefit from simultaneous liver-kidney transplantation (SLK) over liver transplant alone (LTA) in recipients with moderate renal dysfunction is not well understood. Moreover, the impact of deceased donor organ quality in SLK survival has not been well described in the literature. Methods The Scientific Registry of Transplant Recipients was studied for adult recipients receiving LTA (N = 2700) or SLK (N = 1361) with moderate renal insufficiency between 2003 and 2013. The study cohort was stratified into 4 groups based on serum creatinine (<2 mg/dl versus ≥2 mg/dl) and dialysis status at listing and transplant. The patients with end-stage renal disease and requiring acute dialysis more than 3 months before transplantation were excluded. A propensity score matching was performed in each stratified group to factor out imbalances between the SLK and LTA regarding covariate distribution and to reduce measured confounding. Donor quality was assessed with liver donor risk index. The primary outcome of interest was posttransplant mortality. Results In multivariable propensity score-matched Cox proportional hazard models, SLK led to decrease in posttransplant mortality compared with LTA across all 4 groups, but only reached statistical significance (hazard ratio 0.77; 95% confidence interval, 0.62–0.96) in the recipients not exposed to dialysis and serum creatinine ≥ 2 mg/dl at transplant (mortality incidence rate per patient-year 5.7% in SLK vs. 7.6% in LTA, P = 0.005). The decrease in mortality was observed among SLK recipients with better quality donors (liver donor risk index < 1.5). Discussion Exposure to pretransplantation dialysis and donor quality affected overall survival among SLK recipients.

Propensity score-based survival benefit of simultaneous liver-kidney transplant over liver transplant alone for recipients with pretransplant renal dysfunction. Liver Transpl 2016; 22:71-9.

Abstract
The survival benefit of simultaneous liver-kidney transplantation (SLKT) over liver transplantation alone (LTA) is unclear from the current literature. Additionally, the role of donor kidney quality, measured by the kidney donor risk index (KDRI), in survival benefit of SLKT is not studied. We compared survival benefit after SLKT and LTA among recipients with similar pretransplant renal dysfunction using novel methodology, specifically with respect to survival probability and area under the survival curve by dialysis status and KDRI. Data were obtained from the Scientific Registry of Transplant Recipients. The study cohort included patients with pre-liver transplantation (LT) renal dysfunction who were wait-listed and received either a SLKT (n = 1326) or a LTA (n = 4283) between March 1, 2002 and December 31, 2009. Inverse Probability of Treatment Weighting-SLKT and LTA survival curves, along with the 5-year area under the survival curve, were computed by dialysis status at transplant. The difference in the area under the curve represents the average additional survival time gained via SLKT over LTA. For patients not on dialysis, SLKT resulted in a significant 3.7-month gain in 5-year mean posttransplant survival time. The decrease in mortality rate differs significantly by KDRI, and an estimated 76% of SLKT recipients received a kidney with KDRI sufficiently low for mortality. The mortality decrease for SLKT was concentrated in the first year after transplant. The difference between SLKT and LTA 5-year mean posttransplant survival time was 1.4 months and was nonsignificant for patients on dialysis. In conclusion, the propensity score-adjusted survival among SLKT and LTA recipients was similar for those who were on dialysis at LT. Although statistically significant, the survival advantage of SLKT over LTA was of marginal clinical significance among patients not on dialysis and occurred only if the donor kidney was of sufficient quality. These results should be considered in the ongoing debate regarding the allocation of kidneys to extra-renal transplant candidates.

Abstract
In February 2002, the United Network for Organ Sharing implemented a system for prioritizing candidates for liver transplantation that was based on the risk of 90-day mortality as determined by the Model for End-Stage Liver Disease (MELD) score. As the MELD score is driven in part by serum creatinine as a marker of kidney function, the prevalence of kidney dysfunction and failure in patients with end-stage liver disease at the time of listing and at transplantation has steadily risen. In this review, we discuss current practices in liver transplantation in patients with kidney dysfunction focusing briefly on the decision to perform simultaneous liver-kidney transplantation. We then discuss pitfalls to the current practices of liver transplantation in patients with kidney dysfunction. We conclude by discussing potential improvements to current practices including the use of the MELD-Na score, alternatives to creatinine and creatinine-based equation for estimating kidney function, and the use of intraoperative kidney replacement therapy during liver transplantation.

Abstract
Background Liver transplantation is performed at large transplant centers worldwide as a
therapeutic intervention for patients with end-stage liver diseases. Aim To analyze the outcomes and incidence of liver transplantation performed at the
University of São Paulo and to compare those with the State of São
Paulo before and after adoption of the Model for End-Stage Liver Disease (MELD)
score. Method Evaluation of the number of liver transplantations before and after adoption of
the MELD score. Mean values and standard deviations were used to analyze normally
distributed variables. The incidence results were compared with those of the State
of São Paulo. Results There was a high prevalence of male patients, with a predominance of middle-aged.
The main indication for liver transplantation was hepatitis C cirrhosis. The mean
and median survival rates and overall survival over ten and five years were
similar between the groups (p>0.05). The MELD score increased over the course
of the study period for patients who underwent liver transplantation (p>0.05).
There were an increased number of liver transplants after adoption of the MELD
score at this institution and in the State of São Paulo (p<0.001). Conclusion The adoption of the MELD score led to increase the number of liver transplants
performed in São Paulo.

Abstract
It is unclear whether a concomitant kidney transplant grants survival benefit to liver transplant (LT) candidates with renal dysfunction (RD). We retrospectively studied LT candidates without RD (n = 714) and LT candidates with RD who underwent either liver transplant alone (RD-LTA; n = 103) or simultaneous liver-kidney transplant (RD-SLKT; n = 68). RD was defined as renal replacement therapy (RRT) requirement or modification of diet in renal disease (MDRD)-glomerular filtration rate (GFR) <25 mL/min/1.73 m(2) . RD-LTAs had worse one-yr post-transplant survival compared to RD-SLKTs (79.6% vs. 91.2%, p = 0.05). However, RD-LTA recipients more often had hepatitis C (60.2% vs. 41.2%, p = 0.004) and more severe liver disease (MELD 37.9 ± 8.1 vs. 32.7 ± 9.1, p = 0.0001). Twenty RD-LTA recipients died in the first post-transplant year. Evaluation of the cause and timing of death relative to native renal recovery revealed that only four RD-LTA recipients might have derived survival benefit from RD-SLKT. Overall, 87% of RD-LTA patients recovered renal function within one month of transplant. One yr after RD-LTA or RD-SLKT, serum creatinine (1.5 ± 1.2 mg/dL vs. 1.4 ± 0.5 mg/dL, p = 0.63) and prevalence of stage 4 or 5 chronic kidney disease (CKD; 5.9% vs. 6.8%, p = 0.11) were comparable. Our series provides little evidence that RD-SLKT would have yielded substantial short-term survival benefit to RD-LTA recipients.

Abstract
There are complex risk-benefit tradeoffs with different transplantation strategies for end-stage liver disease patients on renal support. Using a Markov discrete-time state transition model, we compared survival for this group with 3 strategies: simultaneous liver-kidney (SLK) transplantation, liver transplantation alone (LTA) followed by immediate kidney transplantation if renal function did not recover, and LTA followed by placement on the kidney transplant wait list. Patients were followed for 30 years from the age of 50 years. The probabilities of events were synthesized from population data and clinical trials according to Model for End-Stage Liver Disease (MELD) scores (21-30 and >30) to estimate input parameters. Sensitivity analyses tested the impact of uncertainty on survival. Overall, the highest survival rates were seen with SLK transplantation for both MELD score groups (82.8% for MELD scores of 21-30 and 82.5% for MELD scores > 30 at 1 year), albeit at the cost of using kidneys that might not be needed. Liver transplantation followed by kidney transplantation led to higher survival rates (77.3% and 76.4%, respectively, at 1 year) than placement on the kidney transplant wait list (75.1% and 74.3%, respectively, at 1 year). When uncertainty was considered, the results indicated that the waiting time and renal recovery affected conclusions about survival after SLK transplantation and liver transplantation, respectively. The subgroups with the longest durations of pretransplant renal replacement therapy and highest MELD scores had the largest absolute increases in survival with SLK transplantation versus sequential transplantation. In conclusion, the findings demonstrate the inherent tension in choices about the use of available kidneys and suggest that performing liver transplantation and using renal transplantation only for those who fail to recover their native renal function could free up available donor kidneys. These results could inform discussions about transplantation policy.

Abstract
Liver transplantation (LT) for patients with renal dysfunction is frequently complicated by major fluid shifts, acidosis, and electrolyte and coagulation abnormalities. Continuous renal replacement therapy (CRRT) has been previously shown to ameliorate these problems. We describe the safety and clinical outcomes of intraoperative hemodialysis (IOHD) during LT for a group of patients with high Model for End-Stage Liver Disease (MELD) scores. We performed a retrospective study at our institution of patients who underwent IOHD from 2002 to 2012. Seven hundred thirty-seven patients underwent transplantation, and 32% received IOHD. The mean calculated MELD score was 37, with 38% having a MELD score ≥ 40. Preoperatively, 61% were in the intensive care unit, 19% were mechanically ventilated, 43% required vasopressor support, and 80% were on some form of renal replacement therapy at the time of transplantation, the majority being on CRRT. Patients on average received 35 U of blood products and 4.8 L of crystalloids without significant changes in hemodynamics or electrolytes. The average urine output was 450 ml, and the average amount of fluid removal with dialysis was 1.8 L. The 90-day patient and dialysis-free survival rates were 90% and 99%, respectively. One-year patient survival rates based on the pretransplant renal replacement status and the MELD status were not statistically different. This is the first large study to demonstrate the safety and feasibility of IOHD in a cohort of critically ill patients with high MELD scores undergoing LT with good patient and renal outcomes.

Abstract
Appropriate recipient selection of simultaneous liver/kidney transplantation (SLKT) remains controversial. In particular, data on liver graft survival in hepatitis C virus-infected (HCV+) SLKT recipients are lacking. We conducted a single-center, retrospective study of HCV+ SLKT recipients (N = 25) in comparison with HCV- SLKT (N = 26) and HCV+ liver transplantation alone (LTA, N = 296). Despite backgrounds of HCV+ and HCV- SLKT being similar, HCV+ SLKT demonstrated significantly impaired 5-year liver graft survival of 35% (HCV- SLKT, 79%, P = 0.004). Compared with HCV+ LTA, induction immunosuppression was more frequently used in HCV+ SLKT. Five-year liver graft survival rate for HCV+ SLKT was significantly lower than that for LTA (35% vs. 74%, respectively, P < 0.001). Adjusted hazard ratio of liver graft loss in HCV+ SLKT was 4.9 (95% confidence interval 2.0-12.1, P = 0.001). HCV+ SLKT recipients were more likely to succumb to recurrent HCV and sepsis compared with LTA (32% vs. 8.8%, P < 0.001 and 24% vs. 8.8%, P = 0.030, respectively). Ten HCV+ SLKT recipients underwent anti-HCV therapy for recurrent HCV; only 1 achieved sustained virological response. HCV+ SLKT is associated with significantly decreased long-term prognosis compared with HCV- SLKT and HCV+ LTA.

Abstract
UNLABELLED Renal dysfunction prior to liver transplantation has a marked impact on post-transplant kidney outcomes. AIM The aim of this study was to assess post-transplant renal function in patients with chronic kidney disease (CKD) receiving orthotopic liver transplantation (OLT) alone. METHODS Retrospective review of 40 OLT recipients with pre-transplant CKD (serum creatinine ≥2 mg/dL for at least three months) at the University of Pennsylvania from February 2002 to July 2010. Primary outcome was estimated glomerular filtration rate (eGFR) up to three years post-transplant. Secondary outcomes included incidence of stage 4 CKD (eGFR < 30 mL/min), need for renal replacement therapy (RRT), meeting criteria for kidney transplant listing (eGFR ≤ 20 mL/min), and mortality. RESULTS Median patient age was 56.5 yr and 48% patients had pre-transplant diabetes. Median serum creatinine at transplant was 2.7 mg/dL (eGFR = 24 mL/min). Median eGFR at one, two, and three yr post-transplant was 35, 34, and 37 mL/min, respectively. Twelve patients (30%) required RRT at a median of 1.21 yr post-transplant and 16 (40%) achieved an eGFR ≤ 20 mL/min at 1.09 yr post-transplant. Mortality was 35% at a median of 1.60 years post-transplant. CONCLUSIONS OLT recipients with pre-transplant CKD have a substantial burden of post-transplant renal dysfunction and high short-term mortality, questioning the rationale for OLT alone in this population.

Abstract
We report two brothers with renal and hepatic polycystic disease who developed end-stage renal failure, requiring hemodialysis, and organomegaly syndrome related to the gigantic size of the liver and both kidneys. Although there was no liver failure, combined liver and kidney transplantation was performed owing to worsening of the clinical condition. In both cases, successful transplantation was accomplished with intra-abdominal engraftment of the liver and kidneys through the same abdominal incision.

Abstract
Although previous consensus recommendations have helped define patients who would benefit from simultaneous liver-kidney transplantation (SLK), there is a current need to reassess published guidelines for SLK because of continuing increase in proportion of liver transplant candidates with renal dysfunction and ongoing donor organ shortage. The purpose of this consensus meeting was to critically evaluate published and registry data regarding patient and renal outcomes following liver transplantation alone or SLK in liver transplant recipients with renal dysfunction. Modifications to the current guidelines for SLK and a research agenda were proposed.

Abstract
BACKGROUND The role of combined liver-kidney transplantation (CLKT) for cirrhotic patients with renal failure (RF) is controversial. Since the model for end-stage liver disease era, there has been a rise in the number of CLKT. Using the Organ Procurement Transplant Network/United Network for Organ Sharing database, this study was undertaken to compare outcomes of cirrhotic patients with RF who received either liver transplant alone (LTA) or CLKT between 2002 and 2008. METHODS Analysis was limited to cirrhotic patients 18 years old or older, with serum creatinine level 2.5 mg/dL or higher at the time of orthotopic liver transplantation (OLT) or who received dialysis at least twice during the week before OLT. Patients who received CLKT were categorized based on the cause of their underlying RF. RESULTS Overall liver allograft and patient survival rates of LTA patients were significantly lower compared with CLKT patients (P<0.001). CLKT patients with hepatorenal syndrome showed significantly higher patient and liver allograft survival rates. Liver allograft survival was superior among CLKT patients irrespective of whether they received dialysis. Prevalence of posttransplantation RF was higher for LTA patients at 6 months and 3 years of follow-up (P<0.001). LTA was a significant risk factor both for graft loss and mortality. Recipient hepatitis C virus seropositivity, donor age, donor cause of death, and life support at the time of OLT were also risk factors for graft loss and death. CONCLUSIONS Cirrhotic patients with RF, in particular with hepatorenal syndrome, CLKT is preferable to LTA because it improves liver allograft and patient survival.

Abstract
Recipients of solitary liver and kidney transplants are living longer, and this increases their risk of long-term complications such as recurrent hepatitis C virus (HCV) and drug-induced nephrotoxicity. These complications may require retransplantation. Since the adoption of the Model for End-Stage Liver Disease, the number of simultaneous liver-kidney transplantation (SLK) procedures has increased. However, there are no standardized criteria for organ allocation to SLK candidates. The aims of this study were to retrospectively compare recipient and graft survival with liver transplantation alone (LTA), SLK, kidney after liver transplantation (KALT), and liver after kidney transplantation (LAKT) and to identify independent risk factors affecting recipient and graft survival. The United Network for Organ Sharing/Organ Procurement and Transplantation Network database (1988-2007) was queried for adult LTA (66,026), SLK (2327), KALT (1738), and LAKT procedures (242). After adjustments for potential confounding demographic and clinical variables, there was no difference in recipient mortality rates with LTA and SLK (P = 0.02). However, there was a 15% decreased risk of graft loss with SLK versus LTA (hazard ratio = 0.85, P < 0.001). The recipient and graft survival rates with SLK were higher than the rates with both KALT (P <0.001 and P <0.001) and LAKT (P = 0.003 and P < 0.001). The following were all identified as independent negative predictors of recipient mortality and graft loss: recipient age ≥ 65 years, male sex, black race, HCV/diabetes mellitus status, donor age ≥ 60 years, serum creatinine level ≥2.0 mg/dL, cold ischemia time > 12 hours, and warm ischemia time > 60 minutes. Although the recent increase in the number of SLK procedures performed each year has effectively decreased the number of potential donor kidneys available to patients with end-stage renal disease (ESRD) awaiting kidney transplantation, SLK in patients with end-stage liver disease and ESRD is justified because of the lower risk of graft loss with SLK versus LTA as well as the superior recipient and graft survival with SLK versus serial liver-kidney transplantation.

Abstract
BACKGROUND Since implementation of the Model for End-stage Liver Disease (MELD), the number of simultaneous liver-kidney transplantations (SLKT) has increased in the United States. However, predictors and survival benefit of SLKT compared to liver transplantation alone (LTA) are not well defined. METHODS Organ Procurement and Transplantation Network data of patients with end-stage liver disease (ESLD) with estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m(2) who had not been on dialysis while on the waiting list and underwent liver transplantation between 2002 and 2008 were analyzed. To identify predictors of undergoing SLKT versus LTA, multiple logistic regression analysis was performed. Cox proportional hazards regression analysis was used to assess the association between SLKT and post-liver transplant patient and graft survival. RESULTS The study cohort comprised 5443 patients; 262 (5%) underwent SLKT and 5181 (95%) underwent LTA. Adjusting for potential confounders, patients who underwent SLKT were 34% less likely to die after liver transplantation than those who underwent LTA (hazard ratio [HR] = 0.66, P = .012) and 33% less likely to have liver graft failure than those who underwent LTA (HR = 0.67, P = .010). Among those who underwent SLKT, 1-, 3-, and 5-year kidney graft survival probabilities were 88%, 80%, and 77%, respectively. Black race and diabetes were associated with a higher likelihood of SLKT versus LTA; female sex, a higher eGFR, and higher MELD score reduced the likelihood of SLKT. CONCLUSIONS Among those with ESLD and kidney dysfunction not on dialysis, post-liver transplant patient and liver graft survivals of patients who underwent SLKT were superior to those of patients who underwent LTA. Whether this reflects differences in the two groups that could not be adjusted in survival models or a specific effect of kidney dysfunction cannot be established.

Abstract
PURPOSE OF REVIEW Hepatorenal syndrome (HRS) is an extremely detrimental complication of cirrhosis, with dismal survival in untreated patients. Continued advances in understanding the pathophysiology of HRS have improved HRS recognition and facilitated development of effective treatment strategies. In this article, we review current concepts in HRS pathophysiology, guidelines for HRS diagnosis, effective treatment options presently available, and controversies surrounding liver versus liver-kidney transplant in transplant candidates. RECENT FINDINGS Published diagnostic criteria for HRS have improved early recognition and intervention in HRS. Increasing data support vasoconstrictor therapy for HRS reversal. Several randomized controlled trials clearly demonstrate efficacy of terlipressin therapy in HRS reversal; although comparable studies are lacking with norepinephrine, preliminary findings suggest that this regime may be the preferred alternative when terlipressin is unavailable for use. In transplant candidates without response to vasoconstrictor therapies, mounting evidence supports simultaneous liver-kidney transplantation if prolonged pretransplant dialysis is required. SUMMARY Prompt identification and therapy initiation in transplant candidates with HRS may improve transplantation rates and posttransplantation outcomes. Future studies identifying optimal vasoconstrictor regimens, alternative therapies, and factors predictive of response to therapy are needed. The appropriate use of simultaneous liver-kidney transplants in patients with HRS remains controversial and requires further analysis by the transplant community.

Abstract
The development of hepatorenal syndrome (HRS) is related to many changes associated with advanced cirrhosis. Because vasoconstrictors correct systemic and splanchnic hemodynamic abnormalities, they are effective treatments for HRS, although only in approximately 40% of HRS patients. Emerging data show that combination treatment with vasoconstrictors and TIPS may yield better outcomes than either alone. All HRS patients should be assessed for liver transplantation. Reversing HRS before transplantation is associated with better long-term survival. Combined liver– kidney transplantation is indicated for those with irreversible kidney injury. Otherwise, there is some merit in performing a liver transplant first and only considering a kidney transplant later.

Abstract
Combined liver kidney transplantation (LKT) can be successfully performed on patients with liver and renal failure; however, outcomes are inferior to liver transplantation alone (OLT). Our aim was to determine the indications for and outcome of LKT and whether patients with longer wait times required more frequent LKT versus OLT alone. We included 18/93 adults who underwent LKT from August 2007 to August 2010 for hepatitis C virus (HCV, n = 7), alcohol (n = 5), nonalcoholic steatohepatitis (n = 2), primary biliary sclerosis, polycystic kidney disease with liver involvement, hepatic adenomatosis, and ischemic hepatitis. Eleven were originally listed for LKT and 7 required listing for-kidney transplantation while awaiting OLT. Eight were on dialysis when first listed and 10 had a low glomerular filtration rate or known kidney disease. The mean calculated Model for End-Stage Liver Disease (MELD) score for LKT was 31.2 ± 3.54. Seven had hepatocellular carcinoma in explants. Two patients had acute cellular kidney rejection that responded to treatment. Recurrence of HCV was documented in 5 patients within 6 months of LKT; 2/5 received HCV therapy (interferon and ribavirin) without renal allograft rejection. One-year liver graft/patient survival was 94% after LKT. One patient died at 6 months post LKT due to severe HCV recurrence. Last mean serum creatinine level was 1.35 ± 0.28 mg/dL for LKT patients. LKT is a safe procedure with favorable outcomes even in patients with a high MELD score. Transplantation of patients with a high MELD score due to regional variations in organ allocation results in additional use of kidneys by OLT patients. Improved organ allocation algorithms in OLT would help to reduce combined transplants, sparing more kidneys.

Abstract
BACKGROUND Renal insufficiency (RI) is common after liver transplantation (LT) and may worsen due to calcineurin inhibitor (CNI) use. We compared LT outcomes using basiliximab induction and delayed CNI initiation to controls with a standard CNI regimen in patients with peri-LT RI. METHODS All adults transplanted January 2004 to December 2007 with peri-LT RI (hemodialysis or creatinine ≥1.5 within 1 week of LT) were included in a retrospective nonrandomized cohort. Outcomes including 30-day and 1-year patient and graft survival and renal function were compared between basiliximab and control groups. RESULTS Two hundred twenty-nine patients (102 basiliximab, 127 controls) were analyzed, mean age 54 years, 72% men, 54% with hepatitis C virus. Mean model for end-stage liver disease (28.2 vs. 20.0; P<0.001) and creatinine (1.9 vs. 1.6; P=0.001) were higher and more patients were on hemodialysis at LT (29% vs. 6%; P<0.001) in the basiliximab group. 30-day patient (99% vs. 97%; P=0.26) and graft survival (98% vs. 95%; P=0.17), 1-year patient (87% vs. 87%; P=0.89) and graft survival (86% vs. 82%; P=0.37), mean creatinine at 1-year (1.5 vs. 1.5 mg/dL; P=0.82), and treated acute rejection (6% vs. 6%; P=0.90) were similar between basiliximab and control groups, respectively. In multivariable logistic regression, basiliximab was not significantly associated with 30-day (odds ratio, 0.10; P=0.11) or 1-year (odds ratio, 0.97; P=0.94) survival, controlling for age, previous LT, model for end-stage liver disease, and hepatitis C virus. CONCLUSIONS Basiliximab induction resulted in 30-day and 1-year patient, graft and renal outcomes comparable with a control group receiving standard CNI-based immunosuppression. Antibody induction with delayed CNI should be further studied prospectively.

Abstract
Hepatitis C virus (HCV) infection is relatively common among patients with end-stage kidney disease (ESKD) on dialysis and kidney transplant recipients. HCV infection in hemodialysis patients is associated with an increased mortality due to liver cirrhosis and hepatocellular carcinoma. The severity of hepatitis C-related liver disease in kidney transplant candidates may predict patient and graft survival after transplant. Liver biopsy remains the gold standard in the assessment of liver fibrosis in this setting. Kidney transplantation, not haemodialysis, seems to be the best treatment for HCV+ve patients with ESKD. Transplantation of kidneys from HCV+ve donors restricted to HCV+ve recipients is safe and associated with a reduction in the waiting time. Simultaneous kidney/liver transplantation (SKL) should be considered for kidney transplant candidates with HCV-related decompensated cirrhosis. Treatment of HCV is more complex in hemodialysis patients, whereas treatment of HCV recurrence in SLK recipients appears effective and safe.

Abstract
BACKGROUND Chronic kidney disease is a common problem in long-term survivors after liver transplantation. Several studies to clarify the risk factors for incidence of chronic kidney disease among liver transplant recipients, including preoperative kidney function, have yielded conflicting results. AIM The aim of this study was to conduct a systematic review of the published medical literature on the impact of pre-transplant kidney function on the occurrence of chronic kidney disease after liver transplantation. METHODS Study-specific relative risks were weighted by the inverse of their variance to obtain fixed- and random-effects pooled estimates for incidence of chronic kidney disease across the published studies. The relative risk of chronic kidney disease after liver transplantation according to pre-transplant glomerular filtration rate was regarded as the most reliable outcome end-point. RESULTS We identified seven studies (38,036 unique liver transplant recipients). A stratified analysis including only studies provided with glomerular filtration rate at transplant reported that the summary estimate of relative risk and 95% confidence intervals (CIs) for developing chronic renal failure among liver transplant recipients with diminished renal function at transplant was 2.12 (95% CI, 1.01; 4.46) (random-effects model). The p value for study heterogeneity was significant (p = 0.0001). Post-transplant chronic kidney disease shows impact on survival; the summary estimate for the adjusted relative risk of all-cause mortality with chronic kidney disease after liver transplant was 4.35 (95% confidence Intervals, 3.34; 5.66), p = 0.0001 (random-effects model). CONCLUSIONS An increased risk of chronic kidney disease frequently exists among liver transplant recipients with reduced renal function at transplant. The occurrence of chronic kidney disease after liver transplantation has a major impact on mortality. Additional studies are needed to understand better the natural history of chronic kidney disease among liver transplant recipients.

Abstract
Over the past 50 years, the pathophysiology and features of the hepatorenal syndrome have been illuminated. The syndrome can be divided into 2 distinct clinical patterns: a rapidly progressive renal failure with an extremely poor prognosis (type 1) and a slow progressive renal failure that correlates with the degree of cirrhosis (type 2). Although our understanding of hepatorenal syndrome continues to grow, our current methods of treating this condition remain limited in their effectiveness. The only definitive therapy is liver transplantation. This is a review of the definition, pathophysiology, and current recommendations for management of hepatorenal syndrome with the critical care nurse in mind.

Abstract
This work is the first report of vacuum-assisted closure (VAC) therapy applied as a life-saving surgical treatment for severe acute pancreatitis occurring in a sequential liver- and kidney-transplanted patient who had percutaneous biliary drainage for obstructive "late-onset" jaundice. Surgical exploration with necrosectomy and sequential laparotomies was performed because of increasing intra-abdominal pressure with hemodynamic instability and intra-abdominal multidrug-resistant sepsis, with increasingly difficult abdominal closure. Repeated laparotomies with VAC therapy (applying a continuous negative abdominal pressure) enabled a progressive, successful abdominal decompression, with the clearance of infection and definitive abdominal wound closure. The application of a negative pressure is a novel approach to severe abdominal sepsis and laparostomy management with a view to preventing compartment syndrome and fatal sepsis, and it can lead to complete abdominal wound closure.
