Banff 2022 Liver Group Meeting report: Monitoring long-term allograft health. Am J Transplant 2024:S1600-6135(24)00204-1. [PMID: 38461883 DOI: 10.1016/j.ajt.2024.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 02/27/2024] [Accepted: 03/06/2024] [Indexed: 03/12/2024]
Abstract
The Banff Working Group on Liver Allograft Pathology met in September 2022. Participants included hepatologists, surgeons, pathologists, immunologists, and histocompatibility specialists. Presentations and discussions focused on the evaluation of long-term allograft health, including noninvasive and tissue monitoring, immunosuppression optimization, and long-term structural changes. Potential revision of the rejection classification scheme to better accommodate and communicate late T cell-mediated rejection patterns and related structural changes, such as nodular regenerative hyperplasia, were discussed. Improved stratification of long-term maintenance immunosuppression to match the heterogeneity of patient settings will be central to improving long-term patient survival. Such personalized therapeutics are in turn contingent on a better understanding and monitoring of allograft status within a rational decision-making approach, likely to be facilitated in implementation with emerging decision-support tools. Proposed revisions to rejection classification emerging from the meeting include the incorporation of interface hepatitis and fibrosis staging. These will be opened to online testing, modified accordingly, and subject to consensus discussion leading up to the next Banff conference.

Abstract
BACKGROUND Emerging data suggest disparities exist in liver transplantation (LT) for alcohol-associated liver disease (ALD). As the incidence of ALD increases, we aimed to characterize recent trends in ALD LT frequency and outcomes, including racial and ethnic disparities. METHODS Using United Network for Organ Sharing/Organ Procurement and Transplantation Network data (2015 through 2021), we evaluated LT frequency, waitlist mortality, and graft survival among US adults with ALD (alcohol-associated hepatitis [AH] and alcohol-associated cirrhosis [AAC]) stratified by race and ethnicity. We used adjusted competing-risk regression analysis to evaluate waitlist outcomes, Kaplan-Meier analysis to illustrate graft survival, and Cox proportional hazards modeling to identify factors associated with graft survival. RESULTS There were 1211 AH and 26 526 AAC new LT waitlist additions, with 970 AH and 15 522 AAC LTs performed. Compared with non-Hispanic White patients (NHWs) with AAC, higher hazards of waitlist death were observed for Hispanic (subdistribution hazard ratio [SHR] = 1.23, 95% confidence interval [CI]: 1.16-1.32), Asian (SHR = 1.22, 95% CI:1. 01-1.47), and American Indian/Alaskan Native (SHR = 1.42, 95% CI: 1.15-1.76) candidates. Similarly, significantly higher graft failures were observed in non-Hispanic Black (HR = 1.32, 95% CI: 1.09-1.61) and American Indian/Alaskan Native (HR = 1.65, 95% CI: 1.15-2.38) patients with AAC than NHWs. We did not observe differences in waitlist or post-LT outcomes by race or ethnicity in AH, although analyses were limited by small subgroups. CONCLUSIONS Significant racial and ethnic disparities exist for ALD LT frequency and outcomes in the United States. Compared with NHWs, racial and ethnic minorities with AAC experience increased risk of waitlist mortality and graft failure. Efforts are needed to identify determinants for LT disparities in ALD that can inform intervention strategies.

Role of Oral Health, Frailty, and Minimal Hepatic Encephalopathy in the Risk of Hospitalization: A Prospective Multi-Center Cohort of Outpatients With Cirrhosis. Clin Gastroenterol Hepatol 2023; 21:1864-1872.e2. [PMID: 36328307 PMCID: PMC11057906 DOI: 10.1016/j.cgh.2022.10.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 09/23/2022] [Accepted: 10/17/2022] [Indexed: 11/05/2022]
Abstract
BACKGROUND & AIMS Hospitalizations are a sentinel event in cirrhosis; however, the changing demographics in patients with cirrhosis require updated hospitalization prediction models. Periodontitis is a risk factor for liver disease and potentially progression. The aim of this study was to determine factors, including poor oral health, associated with 3-month hospitalizations in a multi-center cohort of outpatients with cirrhosis. METHODS North American Consortium for Study of End-stage Liver Disease (NACSELD-3), a new study cohort, recruits outpatients with cirrhosis. Cirrhosis details, demographics, minimal hepatic encephalopathy (MHE), frailty, and comorbid conditions including oral health were collected. All patients were followed for 3 months for nonelective hospitalizations. Multi-variable models were created for this outcome using demographics, cirrhosis details, oral health, MHE, frailty, and comorbid conditions with K-fold internal validation using 25%/75% split. RESULTS A total of 442 outpatients (70% men; 37% compensated; Model for End-stage Liver Disease-Sodium, 12; 42% ascites; and 33% prior HE) were included. MHE was found in 70%, frailty in 10%; and both in 8%. In terms of oral health, 15% were edentulous and 10% had prior periodontitis. Regarding 3-month hospitalizations, 14% were admitted for mostly liver-related reasons. These patients were more likely to be decompensated with higher cirrhosis complications, MHE, frailty and periodontitis history. Multi-variable analysis showed prior periodontitis (P = .026), composite MHE + frailty score (P = .0016), ascites (P = .004), prior HE (P = .008), and hydrothorax (P = .004) were associated with admissions using the training and validation subsets. CONCLUSIONS In a contemporaneous, prospective, multi-center cohort study in outpatients with cirrhosis, poor oral health is significantly associated with 3-month hospitalizations independent of portal hypertensive complications, MHE, and frailty. Potential strategies to reduce hospitalizations should consider oral evaluation in addition to MHE and frailty assessment in practice pathways.

Primary prophylaxis for spontaneous bacterial peritonitis is linked to antibiotic resistance in the Veterans Health Administration. Hepatology 2023; 77:2030-2040. [PMID: 36645215 DOI: 10.1097/hep.0000000000000184] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Accepted: 11/18/2022] [Indexed: 01/17/2023]
Abstract
Spontaneous bacterial peritonitis (SBP) is a major cause of mortality. Although SBP primary prophylaxis (SBPPr) with fluoroquinolones and trimethoprim-sulfamethoxazole (TMP-SMX) is often used, resistance could reduce its benefit. AIM Analyze peritoneal fluid resistance patterns in patients with a first SBP episode with/without SBPPr using the Veterans Health Administration corporate data warehouse and to evaluate national antibiograms. Corporate data warehouse data were extracted using validated International Classification of Disease-9/10 codes, culture, resistance data, and outcomes of 7553 patients who developed their first inpatient SBP between 2009 and 2019 and compared between those with/without SBPPr. Escherichia coli ( E. coli ) and Klebsiella pneumoniae ( K. pneumoniae ) sensitivity to ciprofloxacin and TMP-SMX was calculated using 2021 Veterans Health Administration antibiogram data from all states. The most common isolates were E. coli , K. pneumoniae , and Staphylococcus species. Veterans taking ciprofloxacin SBBPr had higher fluoroquinolone resistance (34% vs 14% no SBPPr, p <0.0001); those taking TMP-SMX had higher TMP-SMX resistance (40% vs 14%, p <0.0001). SBPPr patients showed higher culture positivity, greater length of stay, higher second SBP, and higher probability of liver transplant rates versus no SBPPr. Multivariable models showed SBBPr to be the only variable associated with gram-negative resistance, and SBPPr was associated with a trend toward longer length of stay. E. coli ciprofloxacin sensitivity rates were 50%-87% and 43%-92% for TMP-SMX. K. pneumoniae ciprofloxacin sensitivity was 76%-100% and 72%-100% for TMP-SMX. CONCLUSION Among patients who developed their first SBP episode, there was a higher prevalence of antibiotic resistance in those on SBPPr, with a high rate of fluoroquinolone resistance across the Veterans Health Administration sites.

Admission Serum Metabolites and Thyroxine Predict Advanced Hepatic Encephalopathy in a Multicenter Inpatient Cirrhosis Cohort. Clin Gastroenterol Hepatol 2023; 21:1031-1040.e3. [PMID: 35436625 PMCID: PMC11000256 DOI: 10.1016/j.cgh.2022.03.046] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 03/07/2022] [Accepted: 03/24/2022] [Indexed: 12/18/2022]
Abstract
BACKGROUND & AIMS Grades 3 to 4 hepatic encephalopathy (advanced HE), also termed brain failure, is an organ failure that defines acute-on-chronic liver failure. It is associated with poor outcomes in cirrhosis but cannot be predicted accurately. We aimed to determine the admission metabolomic biomarkers able to predict the development of advanced HE with subsequent validation. METHODS Prospective inpatient cirrhosis cohorts (multicenter and 2-center validation) without brain failure underwent admission serum collection and inpatient follow-up evaluation. Serum metabolomics were analyzed to predict brain failure on random forest analysis and logistic regression. A separate validation cohort also was recruited. RESULTS The multicenter cohort included 602 patients, of whom 144 developed brain failure (105 only brain failure) 3 days after admission. Unadjusted random forest analysis showed that higher admission microbially derived metabolites and lower isoleucine, thyroxine, and lysophospholipids were associated with brain failure development (area under the curve, 0.87 all; 0.90 brain failure only). Logistic regression area under the curve with only clinical variables significantly improved with metabolites (95% CI 0.65-0.75; P = .005). Four metabolites that significantly added to brain failure prediction were low thyroxine and maltose and high methyl-4-hydroxybenzoate sulfate and 3-4 dihydroxy butyrate. Thyroxine alone also significantly added to the model (P = .05). The validation cohort including 81 prospectively enrolled patients, of whom 11 developed brain failure. Admission hospital laboratory thyroxine levels predicted brain failure development despite controlling for clinical variables with high specificity. CONCLUSIONS In a multicenter inpatient cohort, admission serum metabolites, including thyroxine, predicted advanced HE development independent of clinical factors. Admission low local laboratory thyroxine levels were validated as a predictor of advanced HE development in a separate cohort.

Increased Risk of ACLF and Inpatient Mortality in Hospitalized Patients with Cirrhosis and Hepatic Hydrothorax. Dig Dis Sci 2021; 66:3612-3618. [PMID: 33185787 PMCID: PMC11034783 DOI: 10.1007/s10620-020-06677-6] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Accepted: 10/13/2020] [Indexed: 12/30/2022]
Abstract
BACKGROUND Hepatic hydrothorax (HH) remains a difficult-to-treat complication of cirrhosis. AIM To define the mortality, length of stay (LOS), and risk of ACLF in patients admitted with HH. METHODS We utilized the North American Consortium for the Study of End-stage Liver Disease, a prospective cohort of 2868 non-electively hospitalized patients with cirrhosis from 14 tertiary care hepatology centers in North America. A total of 121 patients who required an inpatient thoracentesis (HH group) were compared to 736 patients with refractory ascites without HH, and to 1639 patients without these complications (Other). Patients with a TIPS before or during admission were excluded. RESULTS There were no differences between the groups in age, gender, or liver disease etiology. Admission MELD (20.5, 21.6 vs. 18.7; p < 0.0001) was lower in HH than RA patients but lowest in other patients, respectively. In hospital, HH patients' rate of second infections and ICU transfer were the highest, and their LOS was the longest of all groups. Despite a similar mean discharge MELD compared to RA patients, the 90-day transplant rate was lower. Multivariable modeling showed patients with HH had an increased risk of ACLF (HR = 2.37 vs. RA, HR = 2.56 vs. Other; p = 0.01) even when controlling for MELD score, AKI, second infection, and history of prior 6-month hospitalization. Multivariable modeling also showed that HH increased the risk of inpatient mortality (HR = 2.22 vs. RA alone, HR = 2.31 vs. Other; p = 0.04). CONCLUSIONS HH that required a therapeutic thoracentesis more than doubled the risk of ACLF and inpatient mortality among hospitalized patients with cirrhosis.

Abstract
BACKGROUND & AIMS Progression of stages 2 and 3 acute kidney injury (AKI) in cirrhosis has not been characterized adequately. Patients with higher stages of AKI are believed to have worse outcomes. We assessed outcomes and factors associated with stages 2 and 3 AKI in patients with cirrhosis in the North American Consortium for the Study of End-stage Liver Disease cohort. METHODS We collected data from 2297 hospitalized patients with cirrhosis and ascites from December 2011 through February 2017. Our final analysis included 760 patients who developed AKI per the International Ascites Club 2015 definition (419 with maximum stage 1 and 341 with maximum stage 2 or 3; 63% male; mean age, 58 y). We compared demographic features, laboratory values, AKI treatment response, and survival between patients with maximum stage 1 vs patients with stage 2 or 3 AKI. RESULTS Patients with stage 2 or 3 AKI had higher Model for End-Stage Liver Disease scores (25.9 ± 7.3) than patients with stage 1 AKI (21.9 ± 7.5) (P < .0001). More patients fulfilled systemic inflammatory response syndrome criteria on admission, and more developed a second nosocomial infection (P < .05 for both comparisons). More patients with stage 2 or 3 AKI also had progression of AKI and required dialysis and admission into intensive care units when compared to stage 1 AKI patients (P < .0001 for both). A lower proportion of patients with stage 2 or 3 AKI survived their hospital stay (80% vs 99% with stage 1 AKI; P < .0001), or survived for 30 days without a liver transplant (56% vs 81%; P < .0001). The development of stage 2 or 3 AKI was associated with a higher Model for End-Stage Liver Disease score at the time of admission (P < .0001), presence of systemic inflammatory response on admission (P = .039), and second infection (P < .0001). CONCLUSIONS Based on an analysis of data from the North American Consortium for the Study of End-stage Liver Disease cohort, we found that patients with cirrhosis and more advanced liver disease, as well as a second infection, are more likely to develop stages 2 or 3 AKI, with a progressive course associated with decreased 30-day transplant-free survival. Prevention of AKI progression in patients with cirrhosis and stage 2 or 3 AKI might improve their outcomes.

Insurance Status But Not Race and Ethnicity Are Associated With Outcomes in a Large Hospitalized Cohort of Patients With Cirrhosis. Clin Gastroenterol Hepatol 2021; 19:565-572.e5. [PMID: 32389884 DOI: 10.1016/j.cgh.2020.04.081] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 04/09/2020] [Accepted: 04/27/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Insurance, race, and ethnicity can affect outcomes of patients with cirrhosis, but findings from prospective studies are unclear. We investigated the role of insurance status and race and ethnicity (race/ethnicity) on inpatient and 90-day postdischarge outcomes in a large inpatient cohort of patients with cirrhosis. METHODS We used data from the North American Consortium for the Study of End-Stage Liver Disease (NACSELD) database, from 13 tertiary care centers. Insurance status (uninsured, Medicare, Medicaid, private, and Canadian), race, and ethnicity, were analyzed independent of clinical covariates for their association with transfer to the intensive care unit, acute on chronic liver failure (ACLF), length of hospital stay, inpatient and 90-day death or liver transplantation, and readmission to the hospital within 90 days. Multi-variable analyses and interaction terms were created for insurance, race/ethnicity, and for each outcome, with or without Canadian patients. RESULTS We analyzed data from 2640 patients in the NACSELD database (971 with private insurance, 770 with Medicare, 456 Canadians, 265 with Medicaid, 178 uninsured, 540 non-Caucasian and 220 Hispanic); 23% required admittance to the intensive care unit, 12% developed NACSELD-defined ACLF, 7% died, 5% underwent liver transplantation. Of the 2288 patients discharged from hospital, 13% underwent liver transplantation, 19% died, and 42% were readmitted within 90 days. In the univariate model, uninsured patients accounted for the highest percentage of alcohol- or bleeding-related admissions and the lowest proportion of outpatient cirrhosis-related medication users. Canadians had the lowest rifaximin use and but higher proportions had hepatic encephalopathy, compared with other groups. Lack of insurance was higher among non-Caucasians, regardless of Hispanic ethnicity. In multi-variable analysis, lack of insurance was associated with ACLF (P = .02) and inversely associated with inpatient liver transplant (P = .05) and 90-day liver transplant (P = .02), regardless of whether Canadians were included or specific insurance type. Race or ethnicity were not significantly associated with outcomes. CONCLUSIONS In analyzing the NACSELD database, we found that insurance status, but not race or ethnicity, were independently associated with ACLF and inpatient or 90-day liver transplantation, regardless of inclusion of Canadian patients.

Non-HLA Autoantibodies at 1 Year Negatively Affect 5-Year Native Renal Function in Liver Transplant Recipients. Transplant Proc 2021; 53:1019-1024.

Abstract
BACKGROUND Angiotensin II type-1 receptor (AT1R) and endothelin-1 type A receptor (ETAR) autoantibodies, in addition to allograft injury, can bind native endothelial cells and cause vascular vasoconstriction and fibrosis progression in nontransplanted organs. Therefore, we investigated long-term native renal function in liver transplant (LT) recipients with and without anti-AT1R-Abs and/or anti-ETAR-Abs present in serum. METHODS Primary LT recipients at our single center from January 2000 to April 2009 had their prospectively collected pre-LT (1269 patients) and year 1 post-LT (795 patients) serum tested retrospectively for anti-AT1R-Abs and/or anti-ETAR-Abs. Anti-AT1R-Abs and anti-ETAR-Abs testing was accomplished with a standardized solid phase assay in which >10 U was considered positive. RESULTS Pretransplant anti-AT1R-Abs and/or anti-ETAR-Abs did not change the median delta creatinine from pretransplant to 1 year post-transplant. In multivariable analysis controlling for diabetes (DM) and calcineurin inhibitor (CNI) use, anti-AT1R-Abs and/or anti-ETAR-Abs at 1-year remained statistically significantly associated with a decline in GFR (measured by Modification of Diet in Renal Disease-6) from years 1-5 post-LT (P = .04). In diabetic patients the association with a decline in renal function was more pronounced with (-9.29 mL/min) vs without (-2.28 mL/min) anti-AT1R-Abs and/or anti-ETAR-Abs at year 1, respectively (P = .004). CONCLUSION At 1-year post-LT, the autoantibodies anti-AT1R-Abs and/or anti-ETAR-Abs are associated in multivariable analysis with an increased risk of native renal function decline especially in diabetic patients.

Model for End-Stage Liver Disease-Lactate and Prediction of Inpatient Mortality in Patients With Chronic Liver Disease. Hepatology 2020; 72:1747-1757.

Abstract
BACKGROUND AND AIMS Compared to other chronic diseases, patients with chronic liver disease (CLD) have significantly higher inpatient mortality; accurate models to predict inpatient mortality are lacking. Serum lactate (LA) may be elevated in patients with CLD due to both tissue hypoperfusion as well as decreased LA clearance. We hypothesized that a parsimonious model consisting of Model for End-Stage Liver Disease (MELD) and LA at admission may predict inpatient mortality in patients with CLD. APPROACH AND RESULTS We examined all patients with CLD in two large and diverse health care systems in Texas (North Texas [NTX] and Central Texas [CTX]) between 2010 and 2015. We developed (n = 3,588) and validated (n = 1,804) a model containing MELD and LA measured at the time of hospitalization. We further validated the model in a second cohort of 14 tertiary care hepatology centers that prospectively enrolled nonelective hospitalized patients with cirrhosis (n = 726). MELD-LA was an excellent predictor of inpatient mortality in development (concordance statistic [C-statistic] = 0.81, 95% confidence interval [CI] 0.79-0.82) and both validation cohorts (CTX cohort, C-statistic = 0.85, 95% CI 0.78-0.87; multicenter cohort C-statistic = 0.82, 95% CI 0.74-0.88). MELD-LA performed especially well in patients with specific cirrhosis diagnoses (C-statistic = 0.84, 95% CI 0.81-0.86) or sepsis (C-statistic = 0.80, 95% CI 0.78-0.82). For MELD score 25, inpatient mortality rates were 11.2% (LA = 1 mmol/L), 19.4% (LA = 3 mmol/L), 34.3% (LA = 5 mmol/L), and >50% (LA > 8 mmol/L). A linear increase (P < 0.01) was seen in MELD-LA and increasing number of organ failures. Overall, use of MELD-LA improved the risk prediction in 23.5% of patients compared to MELD alone. CONCLUSIONS MELD-LA (bswh.md/meldla) is an early and objective predictor of inpatient mortality and may serve as a model for risk assessment and guide therapeutic options.

Abstract
BACKGROUND Little is known about patients discharged to hospice following hospitalization for complications of cirrhosis. AIM We sought to understand the current pattern of hospice utilization in patients with cirrhosis by evaluating the North American Consortium for the Study of End-stage Liver Disease (NACSELD) cohort. METHODS Patients with cirrhosis from 14 tertiary-care hepatology centers across North America non-electively hospitalized and prospectively enrolled were evaluated. Exclusion criteria included HIV infection, transplantation or non-hepatic malignancy. Random computer-based propensity score matching was undertaken in a 1:2 ratio based on admission MELD score ± 3 points. RESULTS Totally, 2718 patients were enrolled, 5% (N = 132) were discharged to hospice, 6% (N = 171) died, and the rest were discharged alive. Patients discharged to hospice were older (60 vs. 57 years, p = 0.04), less likely to have had SBP (13% vs. 28%, p = 0.002) and be listed for liver transplantation (11% vs. 26%, p = 0.0007). Features, on multivariable modeling, associated with increased probability of discharge to hospice as opposed to being discharged alive: grade-3-4 hepatic encephalopathy, a higher Child-Turcotte-Pugh (CTP) score, and a higher discharge serum creatinine; however, a higher serum sodium, being listed for transplant and being prescribed rifaximin or a statin were protective from hospice discharge. CONCLUSION Patients with more advanced liver disease, hepatic encephalopathy, renal dysfunction, and those not candidates for liver transplantation were more likely to be discharged to hospice. However, in this sick multinational cohort of cirrhotic inpatients, it seems that hospice is markedly underutilized (5%) since 25% of patients not discharged to hospice died within 6 months.

Abstract
Acute on chronic liver failure (ACLF) is an inflammation-based disorder that occurs in patients with underlying liver disease and is characterized by hepatic and extrahepatic organ failure. Morbidity and mortality are high in patients with ACLF, and therefore prevention and early identification are critical to improve outcome. The purpose of this article is to define ACLF, describe ways to identify the expected outcome of ACLF after development, and illustrate interventions to prevent it and when it is not preventable reduce associated morbidity and mortality.

Abstract
Importance Among liver transplant candidates, obesity and frailty are associated with increased risk of death while they are on the wait-list. However, use of body mass index (BMI) may not detect candidates at a higher risk of death owing to the fact that ascites and muscle wasting are seen across transplant candidates of all BMI measurements. Objective To evaluate whether the association between wait-list mortality and frailty varied by BMI of liver transplant candidates. Design, Setting, and Participants A prospective cohort study was conducted at 9 liver transplant centers in the United States from March 1, 2012, to May 1, 2018, among 1108 adult liver transplant candidates without hepatocellular carcinoma. Exposures At outpatient evaluation, the Liver Frailty Index score was calculated (grip strength, chair stands, and balance), with frailty defined as a Liver Frailty Index score of 4.5 or more. Candidates' BMI was categorized as nonobese (18.5-29.9), class 1 obesity (30.0-34.9), and class 2 or greater obesity (≥35.0). Main Outcomes and Measures The risk of wait-list mortality was quantified using competing risks regression by candidate frailty, adjusting for age, sex, race/ethnicity, Model for End-stage Liver Disease Sodium score, cause of liver disease, and ascites, including an interaction with candidate BMI. Results Of 1108 liver transplant candidates (474 women and 634 men; mean [SD] age, 55 [10] years), 290 (26.2%) were frail; 170 of 670 nonobese candidates (25.4%), 64 of 246 candidates with class 1 obesity (26.0%), and 56 of 192 candidates with class 2 or greater obesity (29.2%) were frail (P = .57). Frail nonobese candidates and frail candidates with class 1 obesity had a higher risk of wait-list mortality compared with their nonfrail counterparts (nonobese candidates: adjusted subhazard ratio, 1.54; 95% CI, 1.02-2.33; P = .04; and candidates with class 1 obesity: adjusted subhazard ratio, 1.72; 95% CI, 0.99-2.99; P = .06; P = .75 for interaction). However, frail candidates with class 2 or greater obesity had a 3.19-fold higher adjusted risk of wait-list mortality compared with nonfrail candidates with class 2 or greater obesity (95% CI, 1.75-5.82; P < .001; P = .047 for interaction). Conclusions and Relevance This study's finding suggest that among nonobese liver transplant candidates and candidates with class 1 obesity, frailty was associated with a 2-fold higher risk of wait-list mortality. However, the mortality risk associated with frailty differed for candidates with class 2 or greater obesity, with frail candidates having a more than 3-fold higher risk of wait-list mortality compared with nonfrail patients. Frailty assessments may help to identify vulnerable patients, particularly those with a BMI of 35.0 or more, in whom a clinician's visual evaluation may be less reliable to assess muscle mass and nutritional status.

AGA Clinical Practice Update: Coagulation in Cirrhosis. Gastroenterology 2019; 157:34-43.e1.

Abstract
DESCRIPTION This expert review was commissioned and approved by the AGA Institute Clinical Practice Updates Committee and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership. The intent is to evaluate the current data on mechanism of altered coagulation in patients with cirrhosis, provide guidance on the use of currently available testing of the coagulation cascade, and help practitioners use anticoagulation and pro-coagulants appropriately in patients with cirrhosis. METHODS This review is framed around the best practice points, which were derived from the most impactful publications in the area of coagulation in cirrhosis and agreed to by all authors. BEST PRACTICE ADVICE 1: Global tests of clot formation, such as rotational thromboelastometry, thromboelastography, sonorheometry, and thrombin generation, may eventually have a role in the evaluation of clotting in patients with cirrhosis, but currently lack validated target levels. BEST PRACTICE ADVICE 2: In general, clinicians should not routinely correct thrombocytopenia and coagulopathy before low-risk therapeutic paracentesis, thoracentesis, and routine upper endoscopy for variceal ligation in patients with hepatic synthetic dysfunction-induced coagulation abnormalities. BEST PRACTICE ADVICE 3: Blood products should be used sparingly because they increase portal pressure and carry a risk of transfusion-associated circulatory overload, transfusion-related acute lung injury, infection transmission, alloimmunization, and/or transfusion reactions. BEST PRACTICE ADVICE 4: The following transfusion thresholds for management of active bleeding or high-risk procedures may optimize clot formation in advanced liver disease: hematocrit ≥25%, platelet count >50,000, and fibrinogen >120 mg/dL. Commonly utilized thresholds for international normalized ratio correction are not supported by evidence. BEST PRACTICE ADVICE 5: Thrombopoietin agonists are a good alternative to platelet transfusion, but require time (about 10 days) to elevate platelet levels. BEST PRACTICE ADVICE 6: The large volume of fresh frozen plasma required to reach an arbitrary international normalized ratio target, limitations of the usual target, minimal effect on thrombin generation, and adverse effects on portal pressure limit the utility of this agent significantly. BEST PRACTICE ADVICE 7: The 4-factor prothrombin complex concentrate contains both pro- and anticoagulant factors that offer an attractive low-volume therapeutic to rebalance a disturbed hemostatic system. However, dosage is, in part, based on international normalized ratio, which is problematic in cirrhosis, and published experience in liver disease is limited. BEST PRACTICE ADVICE 8: Anti-fibrinolytic therapy may be considered in patients with persistent bleeding from mucosal oozing or puncture wound bleeding consistent with impaired clot integrity. Both ε-aminocaproic acid and tranexamic acid inhibit clot dissolution. Neither is believed to generate a hypercoagulable state, although both may exacerbate pre-existing thrombi. BEST PRACTICE ADVICE 9: Desmopressin releases von Willebrand factor as its primary hemostatic mechanism. As this factor is usually elevated in cirrhosis, the agent lacks a sound evidence-based foundation, but may be useful in patients with concomitant renal failure. BEST PRACTICE ADVICE 10: Systemic heparin infusion is recommended for symptomatic deep vein thrombosis and portal and mesenteric vein thrombosis, but there are unresolved issues regarding monitoring with both the anti-Xa assay and the partial thromboplastin time due to cirrhosis-related antithrombin deficiency (heparin cofactor). BEST PRACTICE ADVICE 11: Treatment of incidental portal and mesenteric vein thrombosis depends on estimated impact on transplantation surgical complexity vs risks of bleeding and falls. Therapy with low-molecular-weight heparin, vitamin K antagonists, and direct-acting anticoagulants improve portal vein repermeation vs observation alone. BEST PRACTICE ADVICE 12: Direct-acting anticoagulants, such as the factor Xa and thrombin inhibitors, are relatively safe and effective in stable cirrhotic patients, but are in need of further study in patients with more advanced liver disease.

Frailty Associated With Waitlist Mortality Independent of Ascites and Hepatic Encephalopathy in a Multicenter Study. Gastroenterology 2019; 156:1675-1682. [PMID: 30668935 PMCID: PMC6475483 DOI: 10.1053/j.gastro.2019.01.028] [Citation(s) in RCA: 137] [Impact Index Per Article: 27.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2018] [Revised: 12/25/2018] [Accepted: 01/03/2019] [Indexed: 12/16/2022]
Abstract
BACKGROUND & AIMS Frailty is associated with mortality in patients with cirrhosis. We measured frailty using 3 simple tests and calculated Liver Frailty Index (LFI) scores for patients at multiple ambulatory centers. We investigated associations between LFI scores, ascites, and hepatic encephalopathy (HE) and mortality. METHODS Adults without hepatocellular carcinoma who were on the liver transplantation waitlist at 9 centers in the United States (N = 1044) were evaluated using the LFI; LFI scores of at least 4.5 indicated that patients were frail. We performed logistic regression analyses to assess associations between frailty and ascites or HE and competing risk regression analyses (with liver transplantation as the competing risk) to estimate sub-hazard ratios (sHRs) of waitlist mortality (death or removal from the waitlist). RESULTS Of study subjects, 36% had ascites, 41% had HE, and 25% were frail. The odds of frailty were higher for patients with ascites (adjusted odd ratio 1.56, 95% confidence interval [CI] 1.15-2.14) or HE (odd ratio 2.45, 95% CI 1.80-3.33) than for those without these features. Larger proportions of frail patients with ascites (29%) or HE (30%) died while on the waitlist compared with patients who were not frail (17% of patients with ascites and 20% with HE). In univariable analysis, ascites (sHR 1.52, 95% CI 1.14-2.05), HE (sHR 1.84, 95% CI 1.38-2.45), and frailty (sHR 2.38, 95% CI 1.77-3.20) were associated with waitlist mortality. In adjusted models, only frailty remained significantly associated with waitlist mortality (sHR 1.82, 95% CI 1.31-2.52); ascites and HE were not. CONCLUSIONS Frailty is a prevalent complication of cirrhosis that is observed more frequently in patients with ascites or HE and independently associated with waitlist mortality. LFI scores can be used to objectively quantify risk of death related to frailty-in excess of liver disease severity-in patients with cirrhosis.

Abstract
BACKGROUND AND AIMS Over the last decade, liver transplantation of sicker, older non-hepatitis C cirrhotics with multiple co-morbidities has increased in the United States. We sought to identify an easily applicable set of recipient factors among HCV negative adult transplant recipients associated with significant morbidity and mortality within five years after liver transplantation. METHODS We collected national (n = 31,829, 2002-2015) and center-specific data. Coefficients of relevant recipient factors were converted to weighted points and scaled from 0-5. Recipient factors associated with graft failure included: ventilator support (five patients; hazard ratio [HR] 1.59; 95% CI 1.48-1.72); recipient age >60 years (three patients; HR 1.29; 95% CI 1.23-1.36); hemodialysis (three patients; HR 1.26; 95% CI 1.16-1.37); diabetes (two patients; HR 1.20; 95% CI 1.14-1.27); or serum creatinine ≥1.5 mg/dl without hemodialysis (two patients; HR 1.15; 95% CI 1.09-1.22). RESULTS Graft survival within five years based on points (any combination) was 77.2% (0-4), 69.1% (5-8) and 57.9% (>8). In recipients with >8 points, graft survival was 42% (model for end-stage liver disease [MELD] score <25) and 50% (MELD score 25-35) in recipients receiving grafts from donors with a donor risk index >1.7. In center-specific data within the first year, subjects with ≥5 points (vs. 0-4) had longer hospitalization (11 vs. 8 days, p <0.01), higher admissions for rehabilitation (12.3% vs. 2.7%, p <0.01), and higher incidence of cardiac disease (14.2% vs. 5.3%, p <0.01) and stage 3 chronic kidney disease (78.6% vs. 39.5%, p = 0.03) within five years. CONCLUSION The impact of co-morbidities in an MELD-based organ allocation system need to be reassessed. The proposed clinical tool may be helpful for center-specific assessment of risk of graft failure in non-HCV patients and for discussion regarding relevant morbidity in selected subsets. LAY SUMMARY Over the last decade, liver transplantation of sicker, older patient with multiple co-morbidities has increased. In this study, we show that a set of recipient factors (recipient age >60 years, ventilator status, diabetes, hemodialysis and creatinine >1.5 mg/dl) can help identify patients that may not do well after transplant. Transplanting sicker organs in patients with certain combinations of these characteristics leads to lower survival.

Abstract
The presence of preexisting (memory) or de novo donor-specific HLA antibodies (DSAs) is a known barrier to successful long-term organ transplantation. Yet, despite the fact that laboratory tools and our understanding of histocompatibility have advanced significantly in recent years, the criteria to define presence of a DSA and assign a level of risk for a given DSA vary markedly between centers. A collaborative effort between the American Society for Histocompatibility and Immunogenetics and the American Society of Transplantation provided the logistical support for generating a dedicated multidisciplinary working group, which included experts in histocompatibility as well as kidney, liver, heart, and lung transplantation. The goals were to perform a critical review of biologically driven, state-of-the-art, clinical diagnostics literature and to provide clinical practice recommendations based on expert assessment of quality and strength of evidence. The results of the Sensitization in Transplantation: Assessment of Risk (STAR) meeting are summarized here, providing recommendations on the definition and utilization of HLA diagnostic testing, and a framework for clinical assessment of risk for a memory or a primary alloimmune response. The definitions, recommendations, risk framework, and highlighted gaps in knowledge are intended to spur research that will inform the next STAR Working Group meeting in 2019.

NACSELD acute-on-chronic liver failure (NACSELD-ACLF) score predicts 30-day survival in hospitalized patients with cirrhosis. Hepatology 2018; 67:2367-2374.

Abstract
UNLABELLED The North American Consortium for the Study of End-Stage Liver Disease's definition of acute-on-chronic liver failure (NACSELD-ACLF) as two or more extrahepatic organ failures has been proposed as a simple bedside tool to assess the risk of mortality in hospitalized patients with cirrhosis. We validated the NACSELD-ACLF's ability to predict 30-day survival (defined as in-hospital death or hospice discharge) in a separate multicenter prospectively enrolled cohort of both infected and uninfected hospitalized patients with cirrhosis. We used the NACSELD database of 14 tertiary care hepatology centers that prospectively enrolled nonelective hospitalized patients with cirrhosis (n = 2,675). The cohort was randomly split 60%/40% into training (n = 1,605) and testing (n = 1,070) groups. Organ failures assessed were (1) shock, (2) hepatic encephalopathy (grade III/IV), (3) renal (need for dialysis), and (4) respiratory (mechanical ventilation). Patients were most commonly Caucasian (79%) men (62%) with a mean age of 57 years and a diagnosis of alcohol-induced cirrhosis (45%), and 1,079 patients had an infection during hospitalization. The mean Model for End-Stage Liver Disease score was 19, and the median Child score was 10. No demographic differences were present between the two split groups. Multivariable modeling revealed that the NACSELD-ACLF score, as determined by number of organ failures, was the strongest predictor of decreased survival after controlling for admission age, white blood cell count, serum albumin, Model for End-Stage Liver Disease score, and presence of infection. The c-statistics were 0.8073 for the training set and 0.8532 for the validation set. CONCLUSION Although infection status remains an important predictor of death, NACSELD-ACLF was independently validated in a separate large multinational prospective cohort as a simple, reliable bedside tool to predict 30-day survival in both infected and uninfected patients hospitalized with a diagnosis of cirrhosis.

Beta-blockers in hospitalised patients with cirrhosis and ascites: mortality and factors determining discontinuation and reinitiation. Aliment Pharmacol Ther 2018; 47:78-85. [PMID: 28994122 PMCID: PMC6016372 DOI: 10.1111/apt.14366] [Citation(s) in RCA: 38] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2017] [Revised: 09/14/2017] [Accepted: 09/18/2017] [Indexed: 12/14/2022]
Abstract
BACKGROUND It has been suggested that beta-blockers may increase mortality in patients with cirrhosis and refractory ascites but the effect of beta-blockers discontinuation or reinitiation has not been examined. AIMS To compare, in hospitalised patients with cirrhosis and ascites, the effect of BB on survival and to examine the effect/predictors of beta-blockers discontinuation and reinitiation. METHODS Sub-analysis of NACSELD (North American consortium for the study of end-stage liver disease, database containing prospective data on hospitalised patients with cirrhosis) data from 7 centres enrolling >100 patients with ascites. Data on BB discontinuation and reinitiation were collected by chart review. RESULTS Seven hundred and sixteen patients, 307 (43%) on beta-blockers at admission and 366 (51%) with refractory ascites, were followed to death or hospital discharge. Beta-blocker use was associated with a lower white blood cell count at admission. Beta-blocker use in hospitalised patients with ascites was not associated with a higher mortality, even in those with refractory ascites. No significant changes in mean arterial pressure (MAP) were observed between groups. Discontinuation of beta-blockers (49%) was driven by low MAP, infection and acute kidney injury at time of discontinuation but was not associated with a higher mortality. Beta-blocker reinitiation occurred in 40% prior to discharge and was mainly driven by an increase in MAP. CONCLUSIONS Beta-blocker use is safe in patients with cirrhosis and ascites (including those with refractory ascites) provided beta-blockers are discontinued in the presence of a low MAP and reinitiated once MAP reincreases. A potentially beneficial anti-inflammatory effect of beta-blockers is suggested.

Abstract
OBJECTIVES The International Ascites Club (IAC) recently defined Stage 1 acute kidney injury (AKI) for cirrhosis as an acute increase in serum creatinine (SCr) by ≥0.3 mg/dl or by ≥50% in <48 h from a stable value within 3 months. The baseline SCr may influence AKI risk and patient outcomes. The objective of this study is to determine in cirrhosis whether the baseline SCr has any effect on the in-hospital AKI course and patient survival. METHODS North American Consortium for the Study of End-Stage Liver Disease is a consortium of tertiary-care hepatology centers prospectively enroling non-elective cirrhotic inpatients. Patients with different baseline SCr levels (≤0.5, 0.51-1.0, 1.01-1.5, >1.5 mg/dl) were evaluated for the development of AKI, and compared for AKI outcomes and 30-day survival. RESULTS 653 hospitalized cirrhotics (56.7±10years, 64% men, 30% with infection) were included. The incidence of AKI was 47% of enrolled patients. Patients with higher baseline SCr were more likely to develop AKI, with significantly higher delta and peak SCr (P<0.001) than the other groups, more likely to have a progressive AKI course (P<0.0001), associated with a significantly reduced 30-day survival (P<0.0001). Multivariate logistic regression showed that the delta SCr during an AKI episode to be the strongest factor impacting AKI outcomes and survival (P<0.001), with a delta SCr of 0.70 mg/dl having a 68% sensitivity and 80% specificity for predicting 30-day mortality. CONCLUSIONS Admitted cirrhotic patients with higher baseline SCr are at higher risk for in-hospital development of AKI, and more likely to have AKI progression with reduced survival. Therefore, such patients should be closely monitored and treated promptly for their AKI.

Hepatic Encephalopathy Is Associated With Mortality in Patients With Cirrhosis Independent of Other Extrahepatic Organ Failures. Clin Gastroenterol Hepatol 2017; 15:565-574.e4.

Abstract
BACKGROUND & AIMS Although survival times have increased for patients with cirrhosis, hepatic encephalopathy (HE) remains a major complication and its relative contribution toward mortality in North America is unclear. We investigated whether HE is associated with mortality independent of extrahepatic organ failures (EHOFs). METHODS We collected data from the North American Consortium for Study of End-stage Liver Disease database of hospitalized patients with cirrhosis at tertiary-care centers. EHOFs were defined as need for ventilation (respiratory failure), dialysis (renal failure), or shock (circulatory failure). We analyzed in-hospital and 30-day mortality for patients with varying HE grades and EHOF using adjusted models. RESULTS We analyzed data from 1560 patients, 516 with HE (371 grade 1-2 and 145 grade 3-4). Patients with maximum HE grade 3-4 HE during hospitalization had a higher median model for end-stage liver disease (MELD) score (22) than patients with HE grade 1-2 (MELD score, 19) or no HE (MELD score, 18) (P < .0001). Thirty-day mortality for patients with HE grade 3-4 was significantly higher (38%) than for patients with HE grade 1-2 (8%) or no HE (7%). A total of 107 patients had 2 or more EHOFs, with or without HE; 151 had 1 EHOF and 1302 had no organ failure. Unadjusted mortality was highest for patients with HE of grade 3-4 with 2 EHOFs (n = 44). On regression analysis, HE severity was significantly associated with in-hospital and 30-day mortality, independent of any EHOF, white blood cell count, systemic inflammatory response syndrome, or MELD score (odds ratio, 3.3; P < .0001). CONCLUSIONS In an analysis of more than 1500 patients hospitalized for cirrhosis, HE of grade 3 or 4 was associated with higher in-hospital and 30-day mortality, independently of failure of other organs.

[PMID: 28025746 DOI: 10.1007/s10620-016-4416-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2016] [Accepted: 12/06/2016] [Indexed: 01/30/2023]
Abstract
BACKGROUND Women have lower serum creatinine values than men for similar renal function. AIMS We aimed to determine the differential effect of baseline, peak, and delta creatinine between genders on outcomes in infected hospitalized cirrhotic patients. METHODS North American Consortium for the Study of End-Stage Liver Disease is a 15-center consortium of tertiary care hepatology centers prospectively enrolling infected cirrhotic inpatients. Baseline, peak, and delta creatinine during hospitalization were compared between genders, and their impact on overall survival, transplant-free survival, probability of transplantation, and need for renal replacement therapy (RRT) was analyzed. RESULTS In total, 532 patients with cirrhosis (males = 59% median admission MELD = 20) had significantly lower median baseline (1.07 vs. 1.30 mg/dL, p < 0.0001) and peak creatinine (1.47 vs. 1.59 mg/dL, p = 0.024) in women than men during hospitalization for an infection, but both genders had similar delta creatinine levels (0.30 vs. 0.30 mg/dL, p = 0.957). Thirty-day mortality was similar between genders. RRT was not used more often in women (19 vs. 12%, p = 0.050), and women were 1.8 times more likely than men to receive RRT at the same creatinine (p = 0.028). Both peak and delta creatinine significantly predicted 6-month overall and transplant-free survival (p < 0.0001), but the probability of liver transplantation was affected by the interaction between gender and both peak and delta creatinine. CONCLUSIONS Infected hospitalized cirrhotic women are significantly more likely than men to receive RRT at similar creatinine levels. Gender-specific differences in baseline, peak, and delta creatinine need further investigation to determine whether women need acute kidney injury treatment at lower creatinine thresholds than men.

Sofosbuvir and Velpatasvir Combination Improves Patient-reported Outcomes for Patients With HCV Infection, Without or With Compensated or Decompensated Cirrhosis. Clin Gastroenterol Hepatol 2017; 15:421-430.e6. [PMID: 27847279 DOI: 10.1016/j.cgh.2016.10.037] [Citation(s) in RCA: 62] [Impact Index Per Article: 8.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Revised: 10/14/2016] [Accepted: 10/31/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS The combination of sofosbuvir and velpatasvir is used to treat patients with hepatitis C virus (HCV) infection of different genotypes. We compared the effects of this treatment regimen, with and without ribavirin, on outcomes reported by patients (patient-reported outcomes [PROs]) with HCV infection, with or without cirrhosis. METHODS We performed a post hoc analysis of data collected from phase 3 clinical trials (ASTRAL-1, -2, -3, and -4) of 1701 patients infected with HCV of different genotypes treated with sofosbuvir and velpatasvir with ribavirin for 12 weeks (n = 87), sofosbuvir with ribavirin for 12 or 24 weeks (n = 401), and ribavirin-free sofosbuvir and velpatasvir for 12 or 24 weeks (n = 1213). In all trials, participants completed 4 PRO questionnaires (while blinded to their HCV RNA levels): the Short Form-36, the Functional Assessment of Chronic Illness Therapy-Fatigue, the Chronic Liver Disease Questionnaire-HCV Version, and the Work Productivity and Activity Impairment: Specific Health Problem, at multiple time points. We compared baseline PROs and changes in PROs following treatment in patients without cirrhosis (n = 1112), with compensated cirrhosis (n = 338), and with decompensated cirrhosis (n = 251). RESULTS Baseline PRO scores were as much as 33.5% lower in patients with decompensated cirrhosis than in patients without cirrhosis (P < .05). Following treatment with ribavirin-containing regimens, changes in PRO scores were similar among patients with compensated and decompensated cirrhosis (all P > .01). Treatment with these regimens increased some PRO scores by as much as 11.8% from baseline (P < .05) and reduced others, by as much as 7.1% (P < .05). Despite this, by 12 weeks after cessation of treatment with ribavirin-containing regimens, all PRO decrements resolved; PRO scores increased by as much as 14.2%, and as much as 17.1% at 24 weeks after treatment, regardless of cirrhosis status (all P > .01 between cirrhosis groups). In contrast, treatment with ribavirin-free sofosbuvir and velpatasvir increased PRO scores for patients with compensated cirrhosis, and even more so in patients with decompensated cirrhosis starting at treatment Week 4; no statistically significant decrement was observed at any time point (all 1-sided P values > .05). In multivariate analysis, compensated cirrhosis was associated with a 2.3% to 5.0% greater increase in PRO scores following treatment with sofosbuvir and velpatasvir (P < .05); decompensated cirrhosis was associated with a 5.5%-9.1% greater increase (P < .002). Clinicaltrials.gov number, NCT02201940, NCT02220998, NCT02201953, NCT02201901. CONCLUSIONS In an analysis of data from 4 phase 3 clinical trials, we found that patients with HCV infection (especially those with decompensated cirrhosis) have significant increases in their PRO scores during treatment with sofosbuvir and velpatasvir and after achieving a sustained virologic response.

Efficacy and safety of simeprevir and sofosbuvir with and without ribavirin in subjects with recurrent genotype 1 hepatitis C postorthotopic liver transplant: the randomized GALAXY study. Transpl Int 2017; 30:196-208. [PMID: 27896858 DOI: 10.1111/tri.12896] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2016] [Revised: 09/05/2016] [Accepted: 11/25/2016] [Indexed: 12/14/2022]
Abstract
This prospective, randomized, phase 2 study in subjects with recurrent hepatitis C virus (HCV) genotype 1 postorthotopic liver transplant evaluated once-daily simeprevir 150 mg + sofosbuvir 400 mg, with and without ribavirin 1000 mg. Primary endpoint was proportion of subjects with week 12 sustained virologic response (SVR12). Thirty-three subjects without cirrhosis were randomized 1:1:1 into three arms (stratified by genotype/subtype and Q80K): Arm 1, simeprevir + sofosbuvir + ribavirin, 12 weeks; Arm 2, simeprevir + sofosbuvir, 12 weeks; Arm 3, simeprevir + sofosbuvir, 24 weeks; 13 additional subjects (two with cirrhosis, 11 without cirrhosis) entered Arm 3. All 46 subjects received at least one dose of study drug; median age, 60 years; 73.9% male; 80.4% White; 71.7% genotype/subtype 1a [12 (36.4%) of these had Q80K]; median 4.5 years post-transplant. Among randomized subjects, SVR12 was achieved by 81.8% in Arm 1, 100% in Arm 2, and 93.9% in Arm 3; two subjects did not achieve SVR12: one viral relapse (follow-up week 4; Arm 1) and one missing follow-up week 12 data. In total, five subjects had a serious adverse event, considered unrelated to treatment per investigator. Simeprevir exposure was increased relative to the nontransplant setting, but not considered clinically relevant. Simeprevir + sofosbuvir treatment, with or without ribavirin, was efficacious and well tolerated (ClinicalTrials.gov Identifier: NCT02165189).

A Karnofsky performance status-based score predicts death after hospital discharge in patients with cirrhosis. Hepatology 2017; 65:217-224. [PMID: 27775842 DOI: 10.1002/hep.28900] [Citation(s) in RCA: 60] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2016] [Revised: 09/05/2016] [Accepted: 10/12/2016] [Indexed: 02/06/2023]
Abstract
Identification of patients with cirrhosis at risk for death within 3 months of discharge from the hospital is essential to individualize postdischarge plans. The objective of the study was to identify an easy-to-use prognostic model based on the Karnofsky Performance Status (KPS). The North American Consortium for the Study of End-Stage Liver Disease consists of 16 tertiary-care hepatology centers that prospectively enroll nonelectively admitted cirrhosis patients. Patients enrolled had KPS assessed 1 week postdischarge. KPS was categorized into low (score 10-40), intermediate (50-70), and high (80-100). Of 954 middle-aged patients (57 ± 10 years, 63% men) with a median Model for End-Stage Liver Disease (MELD) score of 17 (interquartile range 13-21), the mortality rates for the low, intermediate, and high performance status groups were 23% (36/159), 11% (55/489), and 5% (15/306), respectively. Low, intermediate, and high performance status was seen in 17%, 51%, and 32% of the cohort, respectively. Low performance status was associated with older age, dialysis, hepatic encephalopathy, longer length of stay, and higher white blood cell count or MELD score at discharge. A model was derived using the three independent predictors of 3-month mortality: KPS, age, and MELD score. This score had better discrimination (area under the receiver operating characteristic curve = 0.74) than a model using MELD (area under the receiver operating characteristic curve = 0.62) or MELD and age (area under the receiver operating characteristic curve = 0.67) to predict 3-month mortality. CONCLUSIONS Cirrhosis patients at risk for 3-month postdischarge mortality can be identified using a novel KPS-based score; this score may be adopted in practice to guide postdischarge early interventions, including the integrated provision of active and palliative management strategies.

Abstract
Acute kidney injury (AKI) and chronic kidney disease (CKD) are common in patients awaiting liver transplantation, and both have a marked impact on the perioperative and long-term morbidity and mortality of liver transplant recipients. Consequently, we reviewed the epidemiology of AKI and CKD in patients with end-stage liver disease, highlighted strategies to prevent and manage AKI, evaluated the changing liver transplant waiting list's impact on kidney function, delineated important considerations in simultaneous liver-kidney transplant selection, and projected possible future transplant policy changes and outcomes. This review was assembled by experts in the field and endorsed by the American Society of Transplantation Liver and Intestinal Community of Practice and Board of Directors and provides practice-based recommendations for preservation of kidney function in patients with end-stage liver disease.

Patient-reported outcomes with sofosbuvir and velpatasvir with or without ribavirin for hepatitis C virus-related decompensated cirrhosis: an exploratory analysis from the randomised, open-label ASTRAL-4 phase 3 trial. Lancet Gastroenterol Hepatol 2016; 1:122-132. [PMID: 28404069 DOI: 10.1016/s2468-1253(16)30009-7] [Citation(s) in RCA: 56] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2016] [Revised: 05/20/2016] [Accepted: 05/26/2016] [Indexed: 01/10/2023]
Abstract
BACKGROUND Hepatitis C virus (HCV) treatment regimens with direct-acting antivirals have not been extensively studied in patients with decompensated cirrhosis. We assessed patient-reported outcomes (PROs) in patients with decompensated cirrhosis given a fixed-dose combination of sofosbuvir and velpatasvir with and without ribavirin. METHODS This study was an exploratory analysis of data collected in a randomised, open-label phase 3 trial (ASTRAL-4) in which patients with HCV-related decompensated cirrhosis were randomly assigned to an all-oral fixed-dose combination of sofosbuvir (400 mg) and velpatasvir (100 mg) once daily for 12 weeks, sofosbuvir and velpatasvir plus oral ribavirin (weight-based 1000 mg or 1200 mg) for 12 weeks, or sofosbuvir and velpatasvir for 24 weeks. Eligible patients were aged 18 years or older with any HCV genotype and decompensated cirrhosis at screening. PROs were collected for the intention-to-treat population using four questionnaires, Short Form (36) Health Survey version 2 (SF-36v2), the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), the Chronic Liver Disease Questionnaire-HCV Version (CLDQ-HCV), and the Work Productivity Activity Index:HCV (WPAI), which were given prospectively to patients before, during, and after treatment. The ASTRAL-4 study is registered with ClinicalTrials.gov, number NCT02201901. FINDINGS Patients were enrolled at 47 hepatology outpatient practices in the USA from Aug 19, 2014, to Dec 19, 2014. 267 patients with HCV-related decompensated cirrhosis were included. In patients given sofosbuvir and velpatasvir for 12 weeks (n=90), clinically significant improvements in PROs started 4 weeks after treatment initiation (+4·4 to +7·5 points on a 0-100 scale at treatment week 4). By the end of treatment, mean improvements in PROs of +5·3 to +16·0 points were noted in all PROs except for role emotional, mental component summary, and social wellbeing scores and work productivity metrics by WPAI:HCV. Similar end-of-treatment improvements (+3·8 to +17·0 points) were observed in patients given sofosbuvir and velpatasvir for 24 weeks (n=90). In patients given sofosbuvir and velpatasvir plus ribavirin (n=87), PRO scores decreased within 4 weeks of treatment (-3·6 to -6·9 points), although scores returned to the baseline levels by the end of treatment. After treatment cessation, significant improvements in all PROs were similar between the treatment groups (all p>0·01) and, by post-treatment week 24, improvements were between +4·9 and +21·2 points. In multivariate analysis, predictors of PRO impairment were treatment naivety, anxiety, use of anxiolytics, use of antidepressants, use of opioids, ribavirin use, the presence of ascites, encephalopathy, insomnia, and depression. INTERPRETATION A clinically significant early (within 4 weeks) and sustained improvement in PROs was observed in patients with HCV-related decompensated cirrhosis who were given sofosbuvir and velpatasvir without ribavirin. A similar regimen with ribavirin resulted in a temporary decrease in PROs, which completely resolved after 8 weeks of treatment. Accompanied by high efficacy, the favourable effect of treatment on PROs improves patients' experience in this difficult-to-treat population with HCV. FUNDING Gilead Sciences.

Terlipressin Plus Albumin Is More Effective Than Albumin Alone in Improving Renal Function in Patients With Cirrhosis and Hepatorenal Syndrome Type 1. Gastroenterology 2016; 150:1579-1589.e2. [PMID: 26896734 DOI: 10.1053/j.gastro.2016.02.026] [Citation(s) in RCA: 173] [Impact Index Per Article: 21.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2015] [Revised: 02/09/2016] [Accepted: 02/10/2016] [Indexed: 02/06/2023]
Abstract
BACKGROUND & AIMS Hepatorenal syndrome type 1 (HRS-1) in patients with cirrhosis and ascites is a functional, potentially reversible, form of acute kidney injury characterized by rapid (<2 wk) and progressive deterioration of renal function. Terlipressin is a synthetic vasopressin analogue that acts, via vascular vasopressin V1 receptors, as a systemic vasoconstrictor. We performed a phase 3 study to evaluate the efficacy and safety of intravenous terlipressin plus albumin vs placebo plus albumin in patients with HRS-1. METHODS Adult patients with cirrhosis, ascites, and HRS-1 (based on the 2007 International Club of Ascites criteria of rapidly deteriorating renal function) were assigned randomly to groups given intravenous terlipressin (1 mg, n = 97) or placebo (n = 99) every 6 hours with concomitant albumin. Treatment continued through day 14 unless the following occurred: confirmed HRS reversal (CHRSR, defined as 2 serum creatinine [SCr] values ≤1.5 mg/dL, at least 40 hours apart, on treatment without renal replacement therapy or liver transplantation) or SCr at or above baseline on day 4. The primary end point was the percentage of patients with confirmed CHRSR. Secondary end points included the incidence of HRS reversal (defined as at least 1 SCr value ≤1.5 mg/dL while on treatment), transplant-free survival, and overall survival. The study was performed at 50 investigational sites in the United States and 2 in Canada, from October 2010 through February 2013. RESULTS Baseline demographic/clinical characteristics were similar between groups. CHRSR was observed in 19 of 97 patients (19.6%) receiving terlipressin vs 13 of 99 patients (13.1%) receiving placebo (P = .22). HRS reversal was achieved in 23 of 97 (23.7%) patients receiving terlipressin vs 15 of 99 (15.2%) receiving placebo (P = .13). SCr decreased by 1.1 mg/dL in patients receiving terlipressin and by only 0.6 mg/dL in patients receiving placebo (P < .001). Decreases in SCr and survival were correlated (r(2) = .882; P < .001). Transplant-free and overall survival were similar between groups. A significantly greater proportion of patients with CHRSR who received terlipressin survived until day 90 than patients who did not have CHRSR after receiving terlipressin (P < .001); this difference was not observed in patients who did vs did not have CHRSR after receiving placebo (P = .28). There were similar numbers of adverse events in each group, but patients in the terlipressin group had more ischemic events. CONCLUSIONS Terlipressin plus albumin was associated with greater improvement in renal function vs albumin alone in patients with cirrhosis and HRS-1. Patients had similar rates of HRS reversal with terlipressin as they did with albumin. ClinicalTrials.gov no: NCT01143246.

Proposed Diagnostic Criteria for Chronic Antibody-Mediated Rejection in Liver Allografts. Am J Transplant 2016; 16:603-14.

Abstract
Donor-specific alloantibodies (DSA) can cause acute antibody-mediated rejection (AMR) in all solid organ allografts. However, long-term outcome in patients with posttransplant DSA needs further study. We retrospectively evaluated prospectively collected paired serum, tissue, and data on 45 matched DSA- positive [DSA+; mean florescence intensity (MFI) ≥10,000] and -negative (DSA-) recipients of a primary liver-only allograft from January 2000 to April 2009. Blinded histopathologic evaluation demonstrated that DSA+ versus DSA- patients were more likely to have subtle inflammation and unique patterns of fibrosis, despite normal or near-normal liver function tests. Stepwise multivariable modeling developed a score (putatively named the chronic AMR [cAMR] score) that included interface activity, lobular inflammation, portal tract collagenization, portal venopathy, sinusoidal fibrosis, and hepatitis C virus status. The score was developed (c = 0.811) and cross-validated (c = 0.704) to predict allograft failure. Two cutoffs were employed to optimize sensitivity and specificity (80% each); a value >27.5 predicted 50% 10-year allograft failure. We propose chronic AMR as a potential new entity defined by (1) a high cAMR score, (2) DSA, and (3) elimination of other potential causes of a similar injury pattern. In conclusion, cAMR score calculation identified liver allograft recipients with DSA at highest risk for allograft loss, although independent validation is needed.

Abstract
BACKGROUND As the population that is infected with the hepatitis C virus (HCV) ages, the number of patients with decompensated cirrhosis is expected to increase. METHODS We conducted a phase 3, open-label study involving both previously treated and previously untreated patients infected with HCV genotypes 1 through 6 who had decompensated cirrhosis (classified as Child-Pugh-Turcotte class B). Patients were randomly assigned in a 1:1:1 ratio to receive the nucleotide polymerase inhibitor sofosbuvir and the NS5A inhibitor velpatasvir once daily for 12 weeks, sofosbuvir-velpatasvir plus ribavirin for 12 weeks, or sofosbuvir-velpatasvir for 24 weeks. The primary end point was a sustained virologic response at 12 weeks after the end of therapy. RESULTS Of the 267 patients who received treatment, 78% had HCV genotype 1, 4% genotype 2, 15% genotype 3, 3% genotype 4, and less than 1% genotype 6; no patients had genotype 5. Overall rates of sustained virologic response were 83% (95% confidence interval [CI], 74 to 90) among patients who received 12 weeks of sofosbuvir-velpatasvir, 94% (95% CI, 87 to 98) among those who received 12 weeks of sofosbuvir-velpatasvir plus ribavirin, and 86% (95% CI, 77 to 92) among those who received 24 weeks of sofosbuvir-velpatasvir. Post hoc analysis did not detect any significant differences in rates of sustained virologic response among the three study groups. Serious adverse events occurred in 19% of patients who received 12 weeks of sofosbuvir-velpatasvir, 16% of those who received 12 weeks of sofosbuvir-velpatasvir plus ribavirin, and 18% of those who received 24 weeks of sofosbuvir-velpatasvir. The most common adverse events were fatigue (29%), nausea (23%), and headache (22%) in all patients and anemia (31%) in the patients receiving ribavirin. CONCLUSIONS Treatment with sofosbuvir-velpatasvir with or without ribavirin for 12 weeks and with sofosbuvir-velpatasvir for 24 weeks resulted in high rates of sustained virologic response in patients with HCV infection and decompensated cirrhosis.

Abstract
BACKGROUND & AIMS There are no effective and safe treatments for chronic hepatitis C virus (HCV) infection of patients who have advanced liver disease. METHODS In this phase 2, open-label study, we assessed treatment with the NS5A inhibitor ledipasvir, the nucleotide polymerase inhibitor sofosbuvir, and ribavirin in patients infected with HCV genotypes 1 or 4. Cohort A enrolled patients with cirrhosis and moderate or severe hepatic impairment who had not undergone liver transplantation. Cohort B enrolled patients who had undergone liver transplantation: those without cirrhosis; those with cirrhosis and mild, moderate, or severe hepatic impairment; and those with fibrosing cholestatic hepatitis. Patients were assigned randomly (1:1) to receive 12 or 24 weeks of a fixed-dose combination tablet containing ledipasvir and sofosbuvir, once daily, plus ribavirin. The primary end point was sustained virologic response at 12 weeks after the end of treatment (SVR12). RESULTS We enrolled 337 patients, 332 (99%) with HCV genotype 1 infection and 5 (1%) with HCV genotype 4 infection. In cohort A (nontransplant), SVR12 was achieved by 86%-89% of patients. In cohort B (transplant recipients), SVR12 was achieved by 96%-98% of patients without cirrhosis or with compensated cirrhosis, by 85%-88% of patients with moderate hepatic impairment, by 60%-75% of patients with severe hepatic impairment, and by all 6 patients with fibrosing cholestatic hepatitis. Response rates in the 12- and 24-week groups were similar. Thirteen patients (4%) discontinued the ledipasvir and sofosbuvir combination prematurely because of adverse events; 10 patients died, mainly from complications related to hepatic decompensation. CONCLUSION The combination of ledipasvir, sofosbuvir, and ribavirin for 12 weeks produced high rates of SVR12 in patients with advanced liver disease, including those with decompensated cirrhosis before and after liver transplantation.

Abstract
BACKGROUND Antiviral treatment with sustained virologic response (SVR) improves survival in liver transplant (LT) recipients, and is especially relevant to patients with advanced recurrent hepatitis C virus (HCV). We assessed the safety and efficacy of protease inhibitor-based triple therapy in patients with recurrent advanced fibrosis and cholestatic hepatitis. METHODS The LT recipients with genotype 1 HCV and advanced fibrosis (F3-4/4) or cholestatic hepatitis treated with telaprevir- or boceprevir-based triple therapy at 6 centers (CRUSH-C consortium) were retrospectively assessed. The primary endpoints were SVR at 12 weeks (SVR12) and safety. RESULTS Forty-five patients with advanced fibrosis and 9 with cholestatic hepatitis (74% men, 57% genotype 1a, 63% previous nonresponders) were included. SVR12 occurred in 51% with advanced fibrosis and 44% with cholestatic hepatitis. Extended rapid virologic response was highly predictive of SVR12. Hispanic ethnicity (odds ratio, 0.16; P = 0.03), previous null/partial response (0.24; P = 0.02), IL28B genotype CC (7.0; P = 0.02), albumin (3.87; P = 0.03), platelet count (1.01; P = 0.02), and steroid use (0.21; P = 0.03) were associated with SVR12. Six (11%) patients died, and hepatic decompensation occurred in 22% with advanced fibrosis and 33% with cholestatic hepatitis. Albumin (0.02; P = 0.001), encephalopathy (12.0; P = 0.04) and Hispanic ethnicity (odds ratio, 6.17; P = 0.01) were associated with death or decompensation. CONCLUSIONS For LT recipients with recurrent advanced HCV and at greatest need of cure, protease inhibitor-based triple therapy achieved approximately 50% SVR12. However, there is significant risk of serious adverse events, arguing for earlier intervention. The availability of treatments with better efficacy and safety is of particular importance for posttransplant patients with advanced disease.
