Early Diagnostic Paracentesis Improves Outcomes of Hospitalized Patients with Cirrhosis and Ascites: A Systematic Review and Meta-Analysis.

INTRODUCTION: Diagnostic paracentesis is recommended for patients with cirrhosis admitted to the hospital, but adherence is suboptimal with unclear impact on clinical outcomes. This meta-analysis aimed to assess the outcomes of early vs. delayed diagnostic paracentesis among hospitalized patients with cirrhosis and ascites. METHODS: We searched multiple databases for studies comparing early vs. delayed diagnostic paracentesis among hospitalized patients with cirrhosis and ascites. The pooled odds ratio (OR) and mean difference (MD) with confidence intervals (CI) for proportional and continuous variables were calculated using the random-effects model. Early diagnostic paracentesis was defined as receiving diagnostic paracentesis within 12-24 hours of admission. The primary outcome was in-hospital mortality. Secondary outcomes were length-of-hospital-stay (LOS), acute kidney injury (AKI), and 30-day readmission. RESULTS: Seven studies (n=78,744) (n=45,533 early vs. n=33,211 delayed diagnostic paracentesis) were included. Early diagnostic paracentesis was associated with lower in-hospital mortality (OR 0.61, 95% CI 0.46-0.82, P=0.001), LOS (MD -4.85 days; 95% CI -6.45, -3.20; P<0.001), and AKI (OR 0.62, 95% CI 0.42-0.92, P=0.02) compared to delayed diagnostic paracentesis, with similar 30-day readmission (OR 1.11, 95% CI 0.52-2.39, P=0.79). Subgroup analysis revealed consistent results for in-hospital mortality whether early diagnostic paracentesis performed within 12 hours (OR 0.51, 95% CI 0.32-0.79, P=0.003, I2=0%) or within 24 hours of admission (OR 0.67, 95% CI 0.45-0.98, P=0.04, I2=82%). Notably, the mortality OR was numerically lower when diagnostic paracentesis was performed within 12 hours, and the results were precise and homogenous (I2=0%). CONCLUSIONS: Findings from this meta-analysis suggest that early diagnostic paracentesis is associated with better patient outcomes. Early diagnostic paracentesis within 12 hours of admission may be associated with the greatest mortality benefit. Data from large-scale randomized trials are needed to validate our findings, especially if there is a greater mortality benefit for early diagnostic paracentesis within 12 hours.

Performance of race-neutral eGFR equations in patients with decompensated cirrhosis.

The 2021 Chronic Kidney Disease Epidemiology Collaboration equation [CKD-EPI 2021] is a race-neutral equation recently developed and rapidly implemented as a reference standard to estimate glomerular filtration rate(GFR). However, its role in cirrhosis has not been examined especially in low GFR. We analyzed the performance of CKD-EPI 2021 compared to other equations with protocol-measured GFR (mGFR) in cirrhosis. We analyzed 2090 unique adult patients with cirrhosis undergoing protocol GFR measurements using iothalamate clearance from 1985 to 2015 when listed for liver transplantation at Baylor University in Dallas and Fort Worth, Texas. Using mGFR as a reference standard, the CKD-EPI 2021 was compared to CKD-EPI 2012, Modification of Diet in Renal Disease-4, Modification of Diet in Renal Disease-6, Royal Free Hospital, and GFR Assessment in Liver disease overall and in certain subgroups (ascites, mGFR ≤ 30 mL/min/1.73 m 2 , diagnosis, Model for End-Stage Liver Disease and gender). We examined bias (difference between eGFR and mGFR), accuracy (p30: eGFR within ± 30% of mGFR) and agreement between eGFR and mGFR categories. CKD-EPI 2021 had the second lowest bias across the entire range of GFR after GFR Assessment in Liver disease (6.6 vs. 4.6 mL/min/1.73 m 2 , respectively, p < 0.001). The accuracy of CKD-EPI 2021 was similar to CKD-EPI 2012 (p30 = 67.8% vs. 67.9%, respectively) which was higher than the other equations ( p < 0.001). It had a similar performance in patients with ascites, by diagnoses, Model for End-Stage Liver Disease subgroups, by gender, and in non-Black patients. However, it had a relatively higher overestimation in mGFR ≤ 30 mL/min/1.73 m 2 than most equations (18.5 mL/min/1.73m 2 , p < 0.001). Specifically, 64% of patients with mGFR ≤ 30 mL/min/1.73m 2 were incorrectly classified as a less severe CKD stage by CKD-EPI 2021. In Blacks, CKD-EPI 2021 underestimated eGFR by 17.9 mL/min/1.73 m 2 , which was higher than the alternate equations except for Royal Free Hospital ( p < 0.001). The novel race-neutral eGFR equation, CKD-EPI 2021, improves the GFR estimation overall but may not accurately capture true kidney function in cirrhosis, specifically at low GFR. There is an urgent need for a race-neutral equation in liver disease reflecting the complexity of kidney function physiology unique to cirrhosis, given implications for organ allocation and dual organ transplant.

Applying Metabolomics and Aptamer-based Proteomics to Determine Pathophysiologic Differences in Decompensated Cirrhosis Patients Hospitalized with Acute Kidney Injury.

A case-control study of 97 patients hospitalized at our institution. We performed aptamer-based proteomics and metabolomics on serum biospecimens obtained within 72 hours of admission. We compared the proteome and metabolome by the AKI phenotype (i.e., HRS-AKI, ATN) and by AKI recovery (decrease in sCr within 0.3 mg/dL of baseline) using ANCOVA analyses adjusting for demographics and clinical characteristics. We completed Random Forest (RF) analyses to identify metabolites and proteins associated with AKI phenotype and recovery. Lasso regression models were developed to highlight metabolites and proteins could improve diagnostic accuracy. Results: ANCOVA analyses showed no metabolomic or proteomic differences by AKI phenotype while identifying differences by AKI recovery status. Our RF and Lasso analyses showed that metabolomics can improve the diagnostic accuracy of both AKI diagnosis and recovery, and aptamer-based proteomics can enhance the diagnostic accuracy of AKI recovery. Discussion: Our analyses provide novel insight into pathophysiologic pathways, highlighting the metabolomic and proteomic similarities between patients with cirrhosis with HRS-AKI and ATN while also identifying differences between those with and without AKI recovery.

The association between mean arterial pressure and acute kidney injury reversal among patients with decompensated cirrhosis.

BACKGROUND AND AIMS: This study informs how mean arterial pressure (MAP) impacts acute kidney injury (AKI) recovery among all patients hospitalized with cirrhosis, regardless of etiology. APPROACH AND RESULTS: We identified incident AKI episodes among subjects in our cohort of patients with decompensated cirrhosis. AKI was defined as a ≥50% increase in creatinine from an outpatient baseline (≥7 days prior) that required hospitalization. Linear mixed effects models were completed to determine the impact between AKI recovery, MAP, and time. To determine the impact of MAP on AKI reversal, we completed time-dependent Cox regression models with time beginning at the time of peak creatinine and ending at death, discharge, or AKI reversal, among those hospitalized with AKI and those with persistent AKI (≥48 h) We identified 702 hospitalized patients with cirrhosis with AKI. We found those with AKI reversal had, on average, higher MAP (2.1 mm Hg, p <0.05) and a greater increase in MAP over time (0.1 mm Hg per hour, p <0.001). Among all 702 hospitalized patients with AKI and adjusted for confounders, each 5 mm Hg increase in MAP was associated with 1.07× the hazard of AKI reversal ( p <0.01). Similarly, among those with persistent AKI after adjusting for confounders, each 5 mm Hg increase in MAP was associated with a 1.19× greater likelihood of AKI reversal ( p <0.001). DISCUSSION: Our data demonstrate that MAP significantly increases the likelihood of AKI recovery regardless of severity or injury or AKI phenotype. We believe these data highlight the importance of MAP as a clinical tool to promote kidney function recovery among patients with cirrhosis hospitalized with AKI.

Controversies in terlipressin and transplantation in the United States: How do we MELD the two?

Hepatorenal syndrome-acute kidney injury (HRS-AKI) is a severe complication of cirrhosis that carries a poor prognosis. The recent Food and Drug Administration approval of terlipressin has substantial implications for managing HRS-AKI and liver allocation in the United States. Terlipressin has been available in Europe for over a decade, and several countries have adapted policy changes such as Model for End-Stage Liver Disease (MELD) score "lock" for HRS-AKI. In this article, we outline the European experience with terlipressin use and explore the question of whether terlipressin treatment for HRS-AKI should qualify for the MELD score "lock" in the United States in those who respond to therapy. Arguments for the MELD lock include protecting waitlist priority for terlipressin responders or partial responders who may miss offers due to MELD reduction in the terlipressin treatment window. Arguments against MELD lock include the fact that terlipressin may produce a durable response and improve overall survival and that equitable access to terlipressin is not guaranteed due to cost and availability. We subsequently discuss the proposed next steps for studying terlipressin implementation in the United States. A successful approach will require the involvement of all major stakeholders and the mobilization of our transplant community to spearhead research in this area.

From past to present to future: Terlipressin and hepatorenal syndrome-acute kidney injury.

Hepatorenal syndrome (HRS) is a rare and highly morbid form of kidney injury unique to patients with decompensated cirrhosis. HRS is a physiologic consequence of portal hypertension, leading to a functional kidney injury that can be reversed by restoring effective circulating volume and renal perfusion. While liver transplantation is the only definitive "cure" for HRS, medical management with vasoconstrictors and i.v. albumin is a cornerstone of supportive care. Terlipressin, a V1a receptor agonist that acts on the splanchnic circulation, has been used for many years outside the United States for the treatment of HRS. However, its recent Food and Drug Administration approval has generated new interest in this population, as a new base of prescribers now work to incorporate the drug into clinical practice. In this article, we review HRS pathophysiology and diagnostic criteria, the clinical use of terlipressin and alternative therapies, and identify areas of future research in the space of HRS and kidney injury in cirrhosis.

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.

Thirty-Day Readmissions Are Largely Not Preventable in Patients With Cirrhosis.

INTRODUCTION: Hospital readmissions are common in patients with cirrhosis, but there are few studies describing readmission preventability. We aimed to describe the incidence, causes, and risk factors for preventable readmission in this population. METHODS: We performed a prospective cohort study of patients with cirrhosis hospitalized at a single center between June 2014 and March 2020 and followed up for 30 days postdischarge. Demographic, clinical, and socioeconomic data, functional status, and quality of life were collected. Readmission preventability was independently and systematically adjudicated by 3 reviewers. Multinomial logistic regression was used to compare those with (i) preventable readmission, (ii) nonpreventable readmission/death, and (iii) no readmission. RESULTS: Of 654 patients, 246 (38%) were readmitted, and 29 (12%) were preventable readmissions. Reviewers agreed on preventability for 70% of readmissions. Twenty-two (including 2 with preventable readmission) died. The most common reasons for readmission were hepatic encephalopathy (22%), gastrointestinal bleeding (13%), acute kidney injury (13%), and ascites (6%), and these reasons were similar between preventable and nonpreventable readmissions. Preventable readmission was often related to paracentesis timeliness, diuretic adjustment monitoring, and hepatic encephalopathy treatment. Compared with nonreadmitted patients, preventable readmission was independently associated with racial and ethnic minoritized individuals (odds ratio [OR] 5.80; 95% CI, 1.96-17.13), nonmarried marital status (OR 2.88; 95% CI, 1.18-7.05), and admission in the prior 30 days (OR 3.45; 95% CI, 1.48-8.04). DISCUSSION: For patients with cirrhosis, readmission is common, but most are not preventable. Preventable readmissions are often related to ascites and hepatic encephalopathy and are associated with racial and ethnic minorities, nonmarried status, and prior admissions.

Plasma exchange for acute and acute-on-chronic liver failure: A systematic review and meta-analysis.

Plasma exchange (PE) is a promising therapeutic option in patients with acute liver failure (ALF) and acute-on-chronic liver failure (ACLF). However, the impact of PE on patient survival in these syndromes is unclear. We aimed to systematically investigate the use of PE in patients with ALF and ACLF compared with standard medical therapy (SMT). We searched PubMed/Embase/Cochrane databases to include all studies comparing PE versus SMT for patients ≥ 18 years of age with ALF and ACLF. Pooled risk ratios (RR) with corresponding 95% CIs were calculated by the Mantel-Haenszel method within a random-effect model. The primary outcome was 30-day survival for ACLF and ALF. Secondary outcomes were overall and 90-day survival for ALF and ACLF, respectively. Five studies, including 343 ALF patients (n = 174 PE vs. n = 169 SMT), and 20 studies, including 5,705 ACLF patients (n = 2,856 PE vs. n = 2,849 SMT), were analyzed. Compared with SMT, PE was significantly associated with higher 30-day (RR 1.41, 95% CI 1.06-1.87, p = 0.02) and overall (RR 1.35, 95% CI 1.12-1.63, p = 0.002) survival in ALF patients. In ACLF, PE was also significantly associated with higher 30-day (RR 1.36, 95% CI 1.22-1.52, p < 0.001) and 90-day (RR 1.21, 95% CI 1.10-1.34, p < 0.001) survival. On subgroup analysis of randomized controlled trials, results remained unchanged in ALF, but no differences in survival were found between PE and SMT in ACLF. In conclusion, PE is associated with improved survival in ALF and could improve survival in ACLF. PE may be considered in managing ALF and ACLF patients who are not liver transplant (LT) candidates or as a bridge to LT in otherwise eligible patients. Further randomized controlled trials are needed to confirm the survival benefit of PE in ACLF.

Prognostic significance of acute kidney injury stage 1B in hospitalized patients with cirrhosis: A US nationwide study.

Understanding the prognostic significance of acute kidney injury (AKI) stage 1B [serum creatinine (sCr) ≥1.5 mg/dL] compared with stage 1A (sCr < 1.5 mg/dL) in a US population is important as it can impact initial management decisions for AKI in hospitalized cirrhosis patients. Therefore, we aimed to define outcomes associated with stage 1B in a nationwide US cohort of hospitalized cirrhosis patients with AKI. Hospitalized cirrhosis patients with AKI in the Cerner-Health-Facts database from January 2009 to September 2017 (n = 6250) were assessed for AKI stage 1 (≥1.5-2-fold increase in sCr from baseline) and were followed for 90 days for outcomes. The primary outcome was 90-day mortality; secondary outcomes were in-hospital AKI progression and AKI recovery. Competing-risk multivariable analysis was performed to determine the independent association between stage 1B, 90-day mortality (liver transplant as a competing risk), and AKI recovery (death/liver transplant as a competing risk). Multivariable logistic regression analysis was performed to determine the independent association between stage 1B and AKI progression. In all, 4654 patients with stage 1 were analyzed: 1A (44.3%) and 1B (55.7%). Stage 1B patients had a significantly higher cumulative incidence of 90-day mortality compared with stage 1A patients, 27.2% versus 19.7% ( p < 0.001). In multivariable competing-risk analysis, patients with stage 1B (vs. 1A) had a higher risk for mortality at 90 days [sHR 1.52 (95% CI 1.20-1.92), p = 0.001] and decreased probability for AKI recovery [sHR 0.76 (95% CI 0.69-0.83), p < 0.001]. Furthermore, in multivariable logistic regression analysis, AKI stage 1B (vs. 1A) was independently associated with AKI progression, OR 1.42 (95% CI 1.14-1.72) ( p < 0.001). AKI stage 1B patients have a significantly higher risk for 90-day mortality, AKI progression, and reduced probability of AKI recovery compared with AKI stage 1A patients. These results could guide initial management decisions for AKI in hospitalized patients with cirrhosis.

Clinical characteristics and prognosis of hospitalized patients with moderate alcohol-associated hepatitis.

BACKGROUND AND AIMS: Little is known about the clinical characteristics and prognosis of hospitalized patients with moderate alcohol-associated hepatitis (mAH) as compared to severe alcohol-associated hepatitis (sAH). Therefore, we aimed to describe the clinical characteristics and risk factors associated with mortality in hospitalized mAH patients. METHODS: Patients hospitalized with alcohol-associated hepatitis (AH) from 1 January 2010 to 31 December 2020 at a large US healthcare system [11 hospitals, one liver transplant centre] were retrospectively analysed for outcomes. Primary outcome was 90-day mortality. AH and mAH were defined according to NIAAA Alcoholic Hepatitis Consortia and Model for End-stage Liver Disease Score ≤ 20 respectively. Multivariable Cox regression analysis was performed to identify independent risk factors associated with 90-day mortality. RESULTS: 1504 AH patients were hospitalized during the study period, of whom 39% (n = 590) had mAH. Compared to sAH patients, mAH patients were older (50 vs. 48 years, p < 0.001) and less likely to have underlying cirrhosis (74% vs. 83%, p < 0.001). There were no differences between the two groups for median alcohol intake g/day (mAH 140.0 vs. sAH 112.0, p = 0.071). The cumulative proportion surviving at 90 days was 88% in mAH versus 62% in sAH (p < 0.001). On multivariable analysis, older age [HR 1.03 (95% CI 1.00-1.06), p = 0.020], corticosteroid use [HR 1.80 (95% CI 1.06-3.06), p = 0.030] and acute kidney injury (AKI) [HR 2.43 (95% CI 1.33-4.47), p = 0.004] were independently associated with 90-day mortality. CONCLUSIONS: mAH carries a 12% mortality rate at 90 days. Age, AKI and corticosteroid use were associated with an increased risk for 90-day mortality. Avoidance of corticosteroids and strategies to reduce the risk of AKI could improve outcomes in mAH patients.

Severe hepatic encephalopathy with mechanical ventilation may inform waitlist priority in acute liver failure: A UNOS database analysis.

BACKGROUND & AIMS: Patients with acute liver failure (ALF) awaiting liver transplantation (LT) may develop multiorgan failure, but organ failure does not impact waitlist prioritization. The aim of this study was to examine the impact of organ failure on waitlist mortality risk and post LT outcomes in patients with ALF. METHODS: We studied adults waitlisted for ALF in the United Network for Organ Sharing (UNOS) database (2002-2019). Organ failures were defined using a previously described Chronic Liver Failure modified sequential organ failure score assessment adapted to UNOS data. Regression analyses of the primary endpoints, 30-day waitlist mortality (Competing risk), and post-LT mortality (Cox-proportional hazards), were performed. Latent class analysis (LCA) was used to determine the organ failures most closely associated with 30-day waitlist mortality. RESULTS: About 3212 adults with ALF were waitlisted, for hepatotoxicity (41%), viral (12%) and unspecified (36%) etiologies. The median number of organ failures was three (interquartile range 1-3). Having ≥3 organ failures (vs. ≤2) was associated with a sub hazard ratio (HR) of 2.7 (95%CI 2.2-3.4)) and a HR of 1.5 (95%CI 1.1-2.5)) for waitlist and post-LT mortality, respectively. LCA identified neurologic and respiratory failure as most impactful on 30-day waitlist mortality. The odds ratios for both organ failures (vs. neither) were higher for mortality 4.5 (95% CI 3.4-5.9) and lower for delisting for spontaneous survival .5 (95%CI .4-.7) and LT .6 (95%CI .5-.7). CONCLUSION: Cumulative organ failure, especially neurologic and respiratory failure, significantly impacts waitlist and post-LT mortality in patients with ALF and may inform risk-prioritized allocation of organs.

Defining an approach for therapeutic strategies in metabolic dysfunction-associated steatotic liver disease after liver transplantation.

Occurrence of metabolic dysfunction-associated steatotic liver disease (MASLD) is common following liver transplantation (LT). MASLD can be classified as a recurrent disease when it occurs in patients receiving LT for metabolic dysfunction-associated steatohepatitis (MASH) or as de novo when it occurs in patients undergoing transplantation for non-metabolic dysfunction-associated steatohepatitis etiologies of liver disease. Fibrosis progression in patients with MASLD is accelerated, with progression to cirrhosis occurring more rapidly compared with the general (ie, non-LT) population. Moreover, the metabolic burden in LT recipients with MASLD is high and synergizes with liver disease to negatively affect the clinical course. Despite the oversized clinical burden of MASLD among LT recipients, there is currently a lack of regulatory approach and pathway for therapeutics development in this patient population. The present document, thus, provides guidance for therapeutics development that incorporates nuances of transplant care in patients with post-LT MASLD to facilitate drug development.

Incidence, clinical characteristics, and risk factors associated with recurrent alcohol-associated hepatitis.

BACKGROUND: Alcohol relapse occurs frequently in alcohol-associated hepatitis (AH) survivors, but data on the frequency and course of recurrent alcohol-associated hepatitis (rAH) are sparse. We investigated the incidence, risk factors, and outcomes of rAH. METHODS: Hospitalized patients with AH from 2010 to 2020 at a large health care system were followed until death/liver transplant, last follow-up, or end of study (December 31, 2021). AH was defined by NIAAA Alcoholic Hepatitis Consortium criteria; rAH was defined a priori as a discrete AH episode >6 months from index AH hospitalization with interim >50% improvement or normalization of total bilirubin. Multivariable competing risk analysis was performed to identify factors associated with rAH. Landmark Kaplan-Meier analysis was performed to compare survival between patients who did versus those who did not develop rAH. RESULTS: Of 1504 hospitalized patients with AH, 1317 (87.6%) survived and were analyzed. During a 3055 person-year follow-up, 116 (8.8%) developed rAH at an annual incidence rate of 3.8% (95% CI: 2.8-4.8). On multivariable competing risk analysis, marital status [sub-HR 0.54 (95% CI: 0.34, 0.92), p=0.01] and medications for alcohol use disorder [sub-HR 0.56 (95% CI: 0.34, 0.91), p=0.02] were associated with a lower risk for rAH. On landmark Kaplan-Meier analysis, the cumulative proportion surviving at 1 year (75% vs. 90%) and 3 years (50% vs. 78%) was significantly lower in patients who developed rAH compared to those who did not develop rAH (log-rank p<0.001). CONCLUSIONS: rAH develops in ~1 in 10 AH survivors and is associated with lower long-term survival. Medications for alcohol use disorder lower the risk for rAH and, therefore, could be a key preventative strategy to improve outcomes.

Trends in Racial and Ethnic Disparities in the Receipt of Lifesaving Procedures for Hospitalized Patients With Decompensated Cirrhosis in the US, 2009-2018.

Importance: Patients with decompensated cirrhosis are hospitalized for acute management with temporizing and lifesaving procedures. Published data to inform intervention development in this area are more than a decade old, and it is not clear whether there have been improvements in disparities in the receipt of these procedures over time. Objective: To evaluate the associations of race and ethnicity with receipt of procedures to treat decompensated cirrhosis over time in the US. Design, Setting, and Participants: This retrospective cross-sectional study analyzed National Inpatient Sample data on cirrhosis admissions among patients with portal hypertension-related complications from 2009 to 2018. All hospital discharges for individuals aged 18 years and older from 2009 to 2018 were assessed for inclusion. Admissions were included if they contained at least 1 cirrhosis-related International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) or International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code and at least 1 cirrhosis-related complication ICD-9-CM or ICD-10-CM code (ie, ascites, hepatic encephalopathy, variceal hemorrhage [VH], and hepatorenal syndrome [HRS]). Data were analyzed from January to June 2022. Exposure: Hospitalization for decompensated cirrhosis. Main Outcomes and Measures: The outcomes of interest were trends in the odds ratios (ORs) for receiving procedures (upper endoscopy, transjugular portosystemic shunt [TIPS], hemodialysis, and liver transplantation [LT]) for decompensated cirrhosis and mortality by race and ethnicity, modeled over time. Multivariable logistic regression was used to assess these outcomes. Results: Among 717 580 admissions (median [IQR] age, 58 [52-67] years), 345 644 patients (9.8%) were Black, 623 991 patients (17.6%) were Hispanic, and 2 340 031 patients (47.4%) were White. Based on the modeled trends, by 2018, there were no significant differences by race or ethnicity in the odds of receiving upper endoscopy for VH. However, Black patients remained less likely than White patients to undergo TIPS for VH (OR, 0.54; 95% CI, 0.47-0.62) and ascites (OR, 0.34; 95% CI, 0.31-0.38). The disparity in receipt of LT improved for Black and Hispanic patients over the study period; however, by 2018, both groups remained less likely to undergo LT than their White counterparts (Black: OR, 0.66; 95% CI, 0.61-0.70; Hispanic: OR, 0.74; 95% CI, 0.70-0.78). The odds of death in Black and Hispanic patients declined over the study period but remained higher in Black patients than White patients in 2018 (OR, 1.08; 95% CI, 1.05-1.11). Conclusions and Relevance: In this cross-sectional study of individuals hospitalized with decompensated cirrhosis, there were racial and ethnic disparities in receipt of complex lifesaving procedures and in mortality that persisted over time.

Incidence and outcomes of acute kidney injury including hepatorenal syndrome in hospitalized patients with cirrhosis in the US.

BACKGROUND & AIMS: Acute kidney injury (AKI) in cirrhosis is common and associated with high morbidity, but the incidence rates of different etiologies of AKI are not well described in the US. We compared incidence rates, practice patterns, and outcomes across etiologies of AKI in cirrhosis. METHODS: We performed a retrospective cohort study of 11 hospital networks, including consecutive adult patients admitted with AKI and cirrhosis in 2019. The etiology of AKI was adjudicated based on pre-specified clinical definitions (prerenal/hypovolemic AKI, hepatorenal syndrome [HRS-AKI], acute tubular necrosis [ATN], other). RESULTS: A total of 2,063 patients were included (median age 62 [IQR 54-69] years, 38.3% female, median MELD-Na score 26 [19-31]). The most common etiology was prerenal AKI (44.3%), followed by ATN (30.4%) and HRS-AKI (12.1%); 6.0% had other AKI, and 7.2% could not be classified. In our cohort, 8.1% of patients received a liver transplant and 36.5% died by 90 days. The lowest rate of death was observed in patients with prerenal AKI (22.2%; p <0.001), while death rates were higher but not significantly different from each other in those with HRS-AKI and ATN (49.0% vs. 52.7%; p = 0.42). Using prerenal AKI as a reference, the adjusted subdistribution hazard ratio (sHR) for 90-day mortality was higher for HRS-AKI (sHR 2.78; 95% CI 2.18-3.54; p <0.001) and ATN (sHR 2.83; 95% CI 2.36-3.41; p <0.001). In adjusted analysis, higher AKI stage and lack of complete response to treatment were associated with an increased risk of 90-day mortality (p <0.001 for all). CONCLUSION: AKI is a severe complication of cirrhosis. HRS-AKI is uncommon and is associated with similar outcomes to ATN. The etiology of AKI, AKI stage/severity, and non-response to treatment were associated with mortality. Further optimization of vasoconstrictors for HRS-AKI and supportive therapies for ATN are needed. IMPACT AND IMPLICATIONS: Acute kidney injury (AKI) in cirrhosis carries high morbidity, and management is determined by the etiology of injury. However, a large and well-adjudicated multicenter database from US centers that uses updated AKI definitions is lacking. Our findings demonstrate that acute tubular necrosis and hepatorenal syndrome have similar outcomes (∼50% mortality at 90 days), though hepatorenal syndrome is uncommon (12% of all AKI cases). These findings represent practice patterns at US transplant/tertiary centers and can be used as a baseline, presenting the situation prior to the adoption of terlipressin in the US.

PROMIS Profile-29 is a valid instrument with distinct advantages over legacy instruments for measuring the quality of life in chronic liver disease.

BACKGROUND AND AIMS: The Patient-Reported Outcomes Measurement Information System (PROMIS) is increasingly used to measure health-related quality of life, yet, it has not been well-studied in chronic liver disease (CLD). This study compares PROMIS Profile-29 to Short-Form Health Survey (SF-36) and Chronic Liver Disease Questionnaire (CLDQ) in patients with CLD. APPROACH AND RESULTS: In all, 204 adult outpatients with CLD completed PROMIS-29, CLDQ, SF-36 and usability questionnaires. Mean scores were compared between groups, the correlation between domain scores was assessed, and floor/ceiling effects were calculated. Etiologies of CLD were NAFLD (44%), hepatitis C (16%), and alcohol (16%). Fifty-three percent had cirrhosis and 33% were Child-Pugh B/C with a mean model for end-stage liver disease score of 12.0. In all 3 tools, the poorest scores were in physical function and fatigue. The presence of cirrhosis or complications was associated with worse scores in most PROMIS Profile-29 domains, indicating known group validity. Strong correlations ( r ≥ 0.7) were present between Profile-29 and SF-36 or CLDQ domains measuring similar concepts, indicating strong convergent validity. Profile-29 was completed faster than SF-36 and CLDQ (5.4 ± 3.0, 6.7 ± 3.3, 6.5 ± 5.2 min, p = 0.003) and rated equally on usability. All CLDQ and SF-36 domains reached the floor or ceiling, while none were noted for Profile-29. These floor/ceiling effects were magnified when assessed in those with and without cirrhosis, indicating the improved depth of measurement by Profile-29. CONCLUSIONS: Profile-29 is a valid, more efficient, well-received tool that provides an improved depth of measurement when compared to SF-36 and CLDQ and, therefore, an ideal tool to measure general health-related quality of life in CLD.

Cirrhotic cardiomyopathy: Predictors of major adverse cardiac events and assessment of reversibility after liver transplant.

BACKGROUND: Major adverse cardiac events (MACE) are a leading cause of morbidity and mortality after orthotopic liver transplantation (OLT). Cirrhotic cardiomyopathy (CCM), initially described in 2005 and revised in 2019, is a source of MACE in patients after OLT. We sought to identify CCM-related predictors of MACE at one-year follow-up after OLT and assess for reversibility of CCM post-OLT. METHODS: This is a retrospective study of adult patients who underwent OLT between 2009 and 2019. All patients had transthoracic echocardiography pre-and post-OLT. Patients with a left ventricular ejection fraction <50 % pre-OLT were excluded. MACE was defined as death, myocardial infarction, congestive heart failure hospitalization, or cardiac arrest. RESULTS: In total, 131 patients were included in this study, of whom 103 and 23 patients met the 2005 and 2019 criteria, respectively. During the follow-up period, 42 patients had MACE and these patients were more likely to have ascites (p = 0.003), hepatorenal syndrome (p = 0.019), and CCM per 2005 criteria (p = 0.023). There were no significant differences between pre-OLT CCM per 2019 criteria (19 % vs 17 %, p = 0.758) or MELD-Na score (21.24 vs 19.40, p = 0.166) for MACE post-OLT. Per the 2005 criteria, 35 of 103 patients recovered and these patients were less likely to have MACE post-OLT (p = 0.012). Per the 2019 criteria, 13 of 23 patients recovered post-OLT but this low number precluded further statistics. CONCLUSION: The 2005 Montreal criteria for CCM were an independent predictor of MACE at one-year follow-up post-OLT while the 2019 CCC criteria for CCM were not. In addition, the 2005 Montreal criteria were more prevalent when compared to 2019 CCC criteria. Finally, the 2005 Montreal criteria were reversible post-OLT 34 % of the time compared to the 2019 CCC criteria which were reversible 57 % of the time.

Longer time to recovery from acute kidney injury is associated with major adverse kidney events in patients with cirrhosis.

BACKGROUND: In patients with cirrhosis and acute kidney injury (AKI), longer time to AKI-recovery may increase the risk of subsequent major-adverse-kidney-events (MAKE). AIMS: To examine the association between timing of AKI-recovery and risk of MAKE in patients with cirrhosis. METHODS: Hospitalised patients with cirrhosis and AKI (n = 5937) in a nationwide database were assessed for time to AKI-recovery and followed for 180-days. Timing of AKI-recovery (return of serum creatinine <0.3 mg/dL of baseline) from AKI-onset was grouped by Acute-Disease-Quality-Initiative Renal Recovery consensus: 0-2, 3-7, and >7-days. Primary outcome was MAKE at 90-180-days. MAKE is an accepted clinical endpoint in AKI and defined as the composite outcome of ≥25% decline in estimated-glomerular-filtration-rate (eGFR) compared with baseline with the development of de-novo chronic-kidney-disease (CKD) stage ≥3 or CKD progression (≥50% reduction in eGFR compared with baseline) or new haemodialysis or death. Landmark competing-risk multivariable analysis was performed to determine the independent association between timing of AKI-recovery and risk of MAKE. RESULTS: 4655 (75%) achieved AKI-recovery: 0-2 (60%), 3-7 (31%), and >7-days (9%). Cumulative-incidence of MAKE was 15%, 20%, and 29% for 0-2, 3-7, >7-days recovery groups, respectively. On adjusted multivariable competing-risk analysis, compared to 0-2-days, recovery at 3-7 and >7-days was independently associated with an increased risk for MAKE: sHR 1.45 (95% CI 1.01-2.09, p = 0.042), sHR 2.33 (95% CI 1.40-3.90, p = 0.001), respectively. CONCLUSION: Longer time to recovery is associated with an increased risk of MAKE in patients with cirrhosis and AKI. Further research should examine interventions to shorten AKI-recovery time and its impact on subsequent outcomes.
