Factors Associated With Recurrence of Underlying Diseases Among Liver Transplant Recipients: A Single-Center Study.

OBJECTIVES: The recurrence of underlying diseases remains a major cause of graft failure after liver transplant. This study aimed to identify factors associated with the recurrence of underlying diseases and investigate the incidence of these factors and recurrence at the main liver transplant center in Iran. MATERIALS AND METHODS: We included adult liver transplant recipients followed at Shiraz Transplant Center between 2011 and 2018 with a confirmed diagnosis of recurrence of underlying disease in our study. We reviewed medical records and extracted data on demographic characteristics, clinical and paraclinical features, medication use, and current status. We used a systematic random sampling method to select a control group of 95 transplant recipients who did not have recurrence. Of 3022 total transplant recipients, 76 recipients experienced a recurrence of their underlying disease. RESULTS: Model for End-Stage Liver Disease score, underlying disease, recipient blood group, donor sex, donor blood group, and rejection frequency were significantly different between study groups with and without recurrence of underlying diseases. Liver transplant recipients with recurrence had lower mean Model for End-Stage Liver Disease score. Recipients with recurrence also had higher rate of drug consumption (eg, prednisolone, tacrolimus, mycophenolate mofetil, sirolimus). Regression analysis showed that donor sex and rejection frequency had an effect on disease recurrence. Death occurred more frequently in liver transplant recipients with recurrence than in the control group (39.5% vs 26.3%), butthe difference was not significant. CONCLUSIONS: Donor sex and acute rejection frequency are independent factors predictive of the recurrence of underlying disease. Modifying risk factors can help minimize the recurrence of underlying diseases after liver transplant.

Effect of Splenectomy on Coagulation and Platelet Function in Adult Liver Transplant Recipients Assessed With Rotational Thromboelastometry and Standard Coagulation Tests.

OBJECTIVES: Splenectomy during liver transplant can affect platelet function. In this study, our primary aim was to assess the perioperative platelet function by rotational thromboelastometry and the effects of splenectomy on platelet function. MATERIALS AND METHODS: We studied 40 consecutive liver transplant recipients with end-stage liver disease (50% as a result of hepatitis C). Patients with splenectomy were compared with patients without splenectomy (n = 20/group). Three platelet function parameters by rotational thromboelastometry were studied: platelet activation with arachidonic acid, platelet activation with adenosine diphosphate, and platelet activation with thrombin receptor-activating peptide 6. Patients were monitored perioperatively and until postoperative day 21. Heparin was infused for 2 days postoperatively (60-180 U/kg/day), followed by administration of subcutaneous low-molecular-weight heparin (40 mg/24 h) on postoperative days 2 and 3 and oral acetylsalicylic acid when platelet count was >50 × 103/µL. RESULTS: Liver disease contributed to low perioperative platelet count and function. Patients showed significant improvement by postoperative day 14 and day 21, particularly after splenectomy. Platelet count was significantly correlated with the 3 platelet function parameters by rotational thromboelastometry (P < .001). Acetyl salicylic acid was required earlier (postoperative day 3) for patients with splenectomy (8/20) but only affected the platelet function represented by platelet activation with arachidonic acid, whereas other platelet activation pathways were less affected. Patients received no transfusions of platelet units. CONCLUSIONS: End-stage liver disease significantly contributed to low platelet function and counts before transplant. Two weeks were required for recovery of patients posttransplant, with further enhancement by splenectomy. Some recipients showed recovery that exceeded the normal reference range, which warranted monitoring. Acetyl salicylic acid only affected 1 platelet activation receptor.

Utilization of older deceased donors for pediatric liver transplant may negatively impact long-term survival.

BACKGROUND: Multiple adult studies have investigated the role of older donors (ODs) in expanding the donor pool. However, the impact of donor age on pediatric liver transplantation (LT) has not been fully elucidated. METHODS: UNOS database was used to identify pediatric (≤18 years) LTs performed in the United States during 2002-22. Donors ≥40 years at donation were classified as older donors (ODs). Propensity analysis was performed with 1:1 matching for potentially confounding variables. RESULTS: A total of 10,024 pediatric liver transplantation (PLT) patients met inclusion criteria; 669 received liver grafts from ODs. Candidates receiving OD liver grafts were more likely to be transplanted for acute liver failure, have higher Model End-Stage Liver Disease/Pediatric End-Stage Liver Disease (MELD/PELD) scores at LT, listed as Status 1/1A at LT, and be in the intensive care unit (ICU) at time of LT (all p < 0.001). Kaplan-Meier (KM) analyses showed that recipients of OD grafts had worse patient and graft survival (p < 0.001) compared to recipients of younger donor (YD) grafts. KM analyses performed on candidates matched for acuity at LT revealed inferior patient and graft survival in recipients of deceased donor grafts (p < 0.001), but not living donor grafts (p > 0.1) from ODs. Cox regression analysis demonstrated that living donor LT, diagnosis of biliary atresia and first liver transplant were favorable predictors of recipient outcomes, whereas ICU stay before LT and transplantation during 2002-12 were unfavorable. CONCLUSION: Livers from ODs were used for candidates with higher acuity. Pediatric recipients of livers from ODs had worse outcome compared to YDs; however, living donor LT from ODs had the least negative impact on recipient outcomes.

Current status of liver transplantation for human immunodeficiency virus-infected patients in mainland China.

According to the report from the Chinese Center for Disease Control and Prevention, the prevalence of human immunodeficiency virus (HIV) infection exceeded 1.2 million individuals by the year 2022, with an annual increase of about 80000 cases. The overall prevalence of hepatitis B surface antigen among individuals co-infected with HIV reached 13.7%, almost twice the rate of the general population in China. In addition to the well-documented susceptibility to opportunistic infections and new malignancies, HIV infected patients frequently experience liver-related organ damage, with the liver and kidneys being the most commonly affected. This often leads to the development of end-stage liver and kidney diseases. Therefore, organ transplantation has emerged as an important part of active treatment for HIV infected patients. However, the curative effect is not satisfactory. HIV infection has been considered a contraindication for organ transplantation. Until the emergence of highly active anti-retroviral therapy in 1996, the once intractable replication of retrovirus was effectively inhibited. With prolonged survival, the failure of important organs has become the main cause of death among HIV patients. Therefore, transplant centers worldwide have resumed exploration of organ transplantation for HIV-infected individuals and reached a positive conclusion. This study provides an overview of the current landscape of HIV-positive patients receiving liver transplantation (LT) in mainland China. To date, our transplant center has conducted LT for eight end-stage liver disease patients co-infected with HIV, and all but one, who died two months postoperatively due to sepsis and progressive multi-organ failure, have survived. Comparative analysis with hepatitis B virus-infected patients during the same period revealed no statistically significant differences in acute rejection reactions, cytomegalovirus infection, bacteremia, pulmonary infections, acute kidney injury, new-onset cancers, or vascular and biliary complications.

Pursuing living donor liver transplantation improves outcomes of patients with autoimmune liver diseases: An intention-to-treat analysis.

Living donor liver transplantation (LDLT) offers the opportunity to decrease waitlist time and mortality for patients with autoimmune liver disease (AILD), autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. We compared the survival of patients with a potential living donor (pLDLT) on the waitlist versus no potential living donor (pDDLT) on an intention-to-treat basis. Our retrospective cohort study investigated adults with AILD listed for a liver transplant in our program between 2000 and 2021. The pLDLT group comprised recipients with a potential living donor. Otherwise, they were included in the pDDLT group. Intention-to-treat survival was assessed from the time of listing. Of the 533 patients included, 244 (43.8%) had a potential living donor. Waitlist dropout was higher for the pDDLT groups among all AILDs (pDDLT 85 [29.4%] vs. pLDLT 9 [3.7%], p < 0.001). The 1-, 3-, and 5-year intention-to-treat survival rates were higher for pLDLT versus pDDLT among all AILDs (95.7% vs. 78.1%, 89.0% vs. 70.1%, and 87.1% vs. 65.5%, p < 0.001). After adjusting for covariates, pLDLT was associated with a 38% reduction in the risk of death among the AILD cohort (HR: 0.62, 95% CI: 0.42-0.93 [ p <0.05]), and 60% among the primary sclerosing cholangitis cohort (HR: 0.40, 95% CI: 0.22-0.74 [ p <0.05]). There were no differences in the 1-, 3-, and 5-year post-transplant survival between LDLT and DDLT (AILD: 95.6% vs. 92.1%, 89.9% vs. 89.4%, and 89.1% vs. 87.1%, p =0.41). This was consistent after adjusting for covariates (HR: 0.97, 95% CI: 0.56-1.68 [ p >0.9]). Our study suggests that having a potential living donor could decrease the risk of death in patients with primary sclerosing cholangitis on the waitlist. Importantly, the post-transplant outcomes in this population are similar between the LDLT and DDLT groups.

Role of albumin-bilirubin score in non-malignant liver disease.

The albumin-bilirubin (ALBI) score, which was proposed to assess the prognosis of patients with hepatocellular carcinoma, has gradually been extended to other liver diseases in recent years, including primary biliary cholangitis, liver cirrhosis, hepatitis, liver transplantation, and liver injury. The ALBI score is often compared with classical scores such as the Child-Pugh and model for end-stage liver disease scores or other noninvasive prediction models. It is widely employed because of its immunity to subjective evaluation indicators and ease of obtaining detection indicators. An increasing number of studies have confirmed that it is highly accurate for assessing the prognosis of patients with chronic liver disease; additionally, it has demonstrated good predictive performance for outcomes beyond survival in patients with liver diseases, such as decompensation events. This article presents a review of the application of ALBI scores in various non-malignant liver diseases.

Red cell distribution width/platelet ratio estimates the 3-year risk of decompensation in Metabolic Dysfunction-Associated Steatotic Liver Disease-induced cirrhosis.

BACKGROUND: For compensated advanced chronic liver disease (cACLD) patients, the first decompensation represents a dramatically worsening prognostic event. Based on the first decompensation event (DE), the transition to decompensated advanced chronic liver disease (dACLD) can occur through two modalities referred to as acute decompensation (AD) and non-AD (NAD), respectively. Clinically Significant Portal Hypertension (CSPH) is considered the strongest predictor of decompensation in these patients. However, due to its invasiveness and costs, CSPH is almost never evaluated in clinical practice. Therefore, recognizing non-invasively predicting tools still have more appeal across healthcare systems. The red cell distribution width to platelet ratio (RPR) has been reported to be an indicator of hepatic fibrosis in Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD). However, its predictive role for the decompensation has never been explored. AIM: In this observational study, we investigated the clinical usage of RPR in predicting DEs in MASLD-related cACLD patients. METHODS: Fourty controls and 150 MASLD-cACLD patients were consecutively enrolled and followed up (FUP) semiannually for 3 years. At baseline, biochemical, clinical, and Liver Stiffness Measurement (LSM), Child-Pugh (CP), Model for End-Stage Liver Disease (MELD), aspartate aminotransferase/platelet count ratio index (APRI), Fibrosis-4 (FIB-4), Albumin-Bilirubin (ALBI), ALBI-FIB-4, and RPR were collected. During FUP, DEs (timing and modaities) were recorded. CSPH was assessed at the baseline and on DE occurrence according to the available Clinical Practice Guidelines. RESULTS: Of 150 MASLD-related cACLD patients, 43 (28.6%) progressed to dACLD at a median time of 28.9 months (29 NAD and 14 AD). Baseline RPR values were significantly higher in cACLD in comparison to controls, as well as MELD, CP, APRI, FIB-4, ALBI, ALBI-FIB-4, and LSM in dACLD-progressing compared to cACLD individuals [all P < 0.0001, except for FIB-4 (P: 0.007) and ALBI (P: 0.011)]. Receiving operator curve analysis revealed RPR > 0.472 and > 0.894 as the best cut-offs in the prediction respectively of 3-year first DE, as well as its superiority compared to the other non-invasive tools examined. RPR (P: 0.02) and the presence of baseline-CSPH (P: 0.04) were significantly and independently associated with the DE. Patients presenting baseline-CSPH and RPR > 0.472 showed higher risk of decompensation (P: 0.0023). CONCLUSION: Altogether these findings suggest the RPR as a valid and potentially applicable non-invasive tool in the prediction of timing and modalities of decompensation in MASLD-related cACLD patients.

An Overview of Liver Transplantation: Current Status, Recent Techniques, and Challenges-Perspectives From a Center in China.

Liver transplantation is the best way to treat end-stage liver disease.With benefits from enhanced techniques, refined management, and advanced medications, liver transplant boasts a commendable 5-year survival rate for recipients. Nevertheless, acquiring the perioperative management and surgical skills essential for liver transplant is a time-consuming process for new surgeons. In addition, COVID-19 has also affected the field. Based on our actual situation in China, we have provided an overview of donor evaluation,recipient selection,transplant procedures, postoperative complications and management, longterm management, and pandemic strategies to guide new clinical surgeons in the field.

Exception Policy Change Increased the Simultaneous Kidney-Liver Transplant Probability of Polycystic Disease in the Centers With High Median MELD at Transplantation.

BACKGROUND: In 2019, Organ Procurement and Transplantation Network/United Network for Organ Sharing changed the exception policy for liver allocation to the median model for end-stage liver disease at transplantation (MMaT). This study evaluated the effects of this change on-waitlist outcomes of simultaneous liver-kidney transplantation (SLKT) for patients with polycystic liver-kidney disease (PLKD). METHODS: Using the Organ Procurement and Transplantation Network/United Network for Organ Sharing registry, 317 patients with PLKD listed for SLKT between January 2016 and December 2021 were evaluated. Waitlist outcomes were compared between prepolicy (Era 1) and postpolicy (Era 2) eras. RESULTS: One-year transplant probability was significantly higher in Era 2 than in Era 1 (55.7% versus 37.9%; P  = 0.001), and the positive effect on transplant probability of Era 2 was significant after risk adjustment (adjusted hazard ratio, 1.76; 95% confidence interval, 1.22-2.54; P  = 0.002 [ref. Era 1]), whereas waitlist mortality was comparable. Transplant centers were separated into the high and low MMaT groups with a score of 29 (median MMaT) and transplant probability in each group between eras was compared. In the high MMaT transplant centers, the 1-y transplant probability was significantly higher in Era 2 (27.5% versus 52.4%; P  = 0.003). The positive effect remained significant in the high MMaT center group (adjusted hazard ratio, 2.79; 95% confidence interval, 1.43-5.46; P  = 0.003 [ref. Era 1]) but not in the low MMaT center group. Although there was a difference between center groups in Era 1 ( P  = 0.006), it became comparable in Era 2 ( P  = 0.54). CONCLUSIONS: The new policy increased 1-y SLKT probability in patients with PKLD and successfully reduced the disparities based on center location.

Expert consensus on the diagnosis and treatment of end-stage liver disease complicated by infections.

End-stage liver disease (ESLD) is a life-threatening clinical syndrome and when complicated with infection the mortality is markedly increased. In patients with ESLD, bacterial or fungal infection can induce or aggravate the occurrence or progression of liver decompensation. Consequently, infections are among the most common complications of disease deterioration. There is an overwhelming need for standardized protocols for early diagnosis and appropriate management for patients with ESLD complicated by infections. Asia Pacific region has the largest number of ESLD patients, due to hepatitis B and the growing population of alcohol and NAFLD. Concomitant infections not only add to organ failure and high mortality but also to financial and healthcare burdens. This consensus document assembled up-to-date knowledge and experience from colleagues across the Asia-Pacific region, providing data on the principles as well as evidence-based current working protocols and practices for the diagnosis and treatment of patients with ESLD complicated by infections.

Management of alcohol-associated liver disease and alcohol use disorder in liver transplant candidates and recipients: Challenges and opportunities.

Alcohol-associated liver disease poses a significant global health burden, with rising alcohol consumption and prevalence of alcohol use disorder (AUD) contributing to increased morbidity and mortality. This review examines the challenges and opportunities in the care of candidates and recipients of liver transplant (LT) with AUD. Despite advancements in posttransplant patient survival, the risk of disease recurrence and alcohol relapse remains substantial. Several challenges have been identified, including (1) rising disease burden of alcohol-associated liver disease, variable transplant practices, and systemic barriers; (2) disparities in mental health therapy access and the impact on transplant; (3) variable definitions, underdiagnosis, and stigma affecting access to care; and (4) post-LT relapse, its risk factors, and consequential harm. The review focuses on the opportunities to improve AUD care for candidates and recipients of LT through effective biochemical monitoring, behavioral and pharmacologic approaches, creating Centers of Excellence for post-LT AUD care, advocating for policy reforms, and ensuring insurance coverage for necessary services as essential steps toward improving patient outcomes. The review also highlights unmet needs, such as the scarcity of addiction specialists, and calls for further research on personalized behavioral treatments, digital health, and value-based care models to optimize AUD care in the LT setting.

Identifying drivers of cost in pediatric liver transplantation.

Understanding the economics of pediatric liver transplantation (LT) is central to high-value care initiatives. We examined cost and resource utilization in pediatric LT nationally to identify drivers of cost and hospital factors associated with greater total cost of care. We reviewed 3295 children (<21 y) receiving an LT from 2010 to 2020 in the Pediatric Health Information System to study cost, both per LT and service line, and associated mortality, complications, and resource utilization. To facilitate comparisons, patients were stratified into high-cost, intermediate-cost, or low-cost tertiles based on LT cost. The median cost per LT was $150,836 [IQR $104,481-$250,129], with marked variance in cost within and between hospital tertiles. High-cost hospitals (HCHs) cared for more patients with the highest severity of illness and mortality risk levels (67% and 29%, respectively), compared to intermediate-cost (60%, 21%; p <0.001) and low-cost (51%, 16%; p <0.001) hospitals. Patients at HCHs experienced a higher prevalence of mechanical ventilation, total parental nutrition use, renal comorbidities, and surgical complications than other tertiles. Clinical (27.5%), laboratory (15.1%), and pharmacy (11.9%) service lines contributed most to the total cost. Renal comorbidities ($69,563) and total parental nutrition use ($33,192) were large, independent contributors to total cost, irrespective of the cost tertile ( p <0.001). There exists a significant variation in pediatric LT cost, with HCHs caring for more patients with higher illness acuity and resource needs. Studies are needed to examine drivers of cost and associated outcomes more granularly, with the goal of defining value and standardizing care. Such efforts may uniquely benefit the sicker patients requiring the strategic resources located within HCHs to achieve the best outcomes.

Therapeutic Plasma Exchange in Children With Acute and Acuteon-Chronic Liver Failure: A Single-Center Experience.

OBJECTIVES: Acute liver failure is a life-threatening condition that may result in death if liver transplant is not performed. The aim of our study was to evaluate patients with acute liver failure or acute-on-chronic liver failure who were followed and treated with therapeutic plasma exchange in a pediatric intensive care unit until they achieved clinical recovery or underwent liver transplant. MATERIALS AND METHODS: In this retrospective, singlecenter study, we included patients with acute liver failure or acute-on-chronic liver failure who received therapeutic plasma exchange between April 2020 and December 2021. Clinical findings, laboratory findings, extracorporeal therapies, Pediatric Risk of Mortality III and liver injury unit scores and pretherapy and posttherapy hepatic encephalopathy scores, Model for End-Stage Liver Disease score, and Pediatric End-Stage Liver Disease score were retrospectively analyzed. RESULTS: Nineteen patients were included in the study. One patient was excluded because of positivity for COVID-19. The mean age of children was 62.06 months, ranging from 5 months to 16 years (12 boys, 6 girls). Thirteen patients (72.2%) had acute liver failure, and 5 patients (27.8%) had acute-on-chronic liver failure. No significant difference was shown for mean liver injury unit score (P = .673) and Pediatric Logistic Organ Dysfunction score (P = .168) between patients who died and patients who received treatment at the inpatient clinic and transplant center. However, Pediatric Risk of Mortality score and the mean Model for End-Stage Liver Disease/Pediatric End-Stage Liver Disease scores before therapeutic plasma exchange and after therapeutic plasma exchange (after 3 consecutive days of treatment) were statistically significant (P = .001 and P = .004). CONCLUSIONS: Therapeutic plasma exchange may assist bridge to liver transplant or assist with spontaneous recovery of liver failure in pediatric patients with acute liver failure or acute-on-chronic liver failure.

Model for end-stage liver disease-3.0 vs. model for end-stage liver disease-sodium: mortality prediction in Korea.

BACKGROUND/AIMS: The model for end-stage liver disease (MELD) serves as an indicator for short-term mortality among patients diagnosed with liver cirrhosis (LC) and is used to prioritize patients for liver transplantation. In 2021, the updated version of MELD, MELD-3.0, was introduced to improve the accuracy of the mortality prediction of MELD. Therefore, this study aimed to compare the efficacy of MELD 3.0 and MELD-Na in predicting mortality among Korean patients with LC. METHODS: A retrospective review was conducted using the medical records of patients diagnosed with LC who were admitted to Konkuk University Hospital From 2011 to 2021. The study calculated the predictive values of MELD-Na and MELD-3.0 for 3- and 6-months mortality using the area under the receiver operating curve (AUROC) and compared the results using the DeLong test. RESULTS: Of the 3,034 patients enrolled in the study, 339 (11.2%) died within 3 months and 421 (14.4%) died within 6 months. The AUROCs values for predicting 3 months mortality were 0.846 for MELD-Na and 0.851 for MELD-3.0. The corresponding AUROC values for predicting 6 months mortality were 0.843 for MELD-Na and 0.848 for MELD-3.0. MELD-3.0 exhibited better discrimination ability than MELD-Na for both 3 (p = 0.03) and 6 months mortality (p = 0.01). CONCLUSION: Our study found a significant difference between the performance of MELD-3.0 and MELD-Na in Korean patients with LC.

Performance of risk prediction models for post-liver transplant patient and graft survival over time.

Given liver transplantation organ scarcity, selection of recipients and donors to maximize post-transplant benefit is paramount. Several scores predict post-transplant outcomes by isolating elements of donor and recipient risk, including the donor risk index, Balance of Risk, pre-allocation score to predict survival outcomes following liver transplantation/survival outcomes following liver transplantation (SOFT), improved donor-to-recipient allocation score for deceased donors only/improved donor-to-recipient allocation score for both deceased and living donors (ID2EAL-D/-DR), and survival benefit (SB) models. No studies have examined the performance of these models over time, which is critical in an ever-evolving transplant landscape. This was a retrospective cohort study of liver transplantation events in the UNOS database from 2002 to 2021. We used Cox regression to evaluate model discrimination (Harrell's C) and calibration (testing of calibration curves) for post-transplant patient and graft survival at specified post-transplant timepoints. Sub-analyses were performed in the modern transplant era (post-2014) and for key donor-recipient characteristics. A total of 112,357 transplants were included. The SB and SOFT scores had the highest discrimination for short-term patient and graft survival, including in the modern transplant era, where only the SB model had good discrimination (C ≥ 0.60) for all patient and graft outcome timepoints. However, these models had evidence of poor calibration at 3- and 5-year patient survival timepoints. The ID2EAL-DR score had lower discrimination but adequate calibration at all patient survival timepoints. In stratified analyses, SB and SOFT scores performed better in younger (< 40 y) and higher Model for End-Stage Liver Disease (≥ 25) patients. All prediction scores had declining discrimination over time, and scores relying on donor factors alone had poor performance. Although the SB and SOFT scores had the best overall performance, all models demonstrated declining performance over time. This underscores the importance of periodically updating and/or developing new prediction models to reflect the evolving transplant field. Scores relying on donor factors alone do not meaningfully inform post-transplant risk.

A retrospective cohort study of socioeconomic deprivation and post-liver transplant survival in adults.

The Area Deprivation Index is a granular measure of neighborhood socioeconomic deprivation. The relationship between neighborhood socioeconomic deprivation and recipient survival following liver transplantation (LT) is unclear. To investigate this, the authors performed a retrospective cohort study of adults who underwent LT at the University of Washington Medical Center from January 1, 2004, to December 31, 2020. The primary exposure was a degree of neighborhood socioeconomic deprivation as determined by the Area Deprivation Index score. The primary outcome was posttransplant recipient mortality. In a multivariable Cox proportional analysis, LT recipients from high-deprivation areas had a higher risk of mortality than those from low-deprivation areas (HR: 1.81; 95% CI: 1.03-3.18, p =0.04). Notably, the difference in mortality between area deprivation groups did not become statistically significant until 6 years after transplantation. In summary, LT recipients experiencing high socioeconomic deprivation tended to have worse posttransplant survival. Further research is needed to elucidate the extent to which neighborhood socioeconomic deprivation contributes to mortality risk and identify effective measures to improve survival in more socioeconomically disadvantaged LT recipients.

Optimization of Kidney Health in Liver Transplant Candidates: Pretransplant Considerations and Modalities.

Patients with decompensated end-stage liver disease (ESLD) are at increased risk for mortality, and only liver transplantation (LT) offers meaningful hope for survival. These patients are at risk for kidney dysfunction through the continuum of care for ESLD including LT. We discuss the role of accurate estimation and measurement of baseline glomerular filtration rate in assessment of kidney dysfunction among those with ESLD. Optimizing kidney function is a vital goal in the management of these patients before LT. In this review, we summarize salient aspects of assessing and optimizing kidney function in this patient population. Precipitating factors and different causes of acute kidney injury are discussed, including hepatorenal syndrome. We further review treatment options for acute kidney injury including volume management. The role of vasopressor therapy, renal replacement therapy, and transjugular intrahepatic portosystemic shunting are discussed.
