Targets to improve quality of care for patients with hepatic encephalopathy: data from a multi-centre cohort. Aliment Pharmacol Ther 2019; 49:1518-1527. [PMID: 31032966 PMCID: PMC6538445 DOI: 10.1111/apt.15265] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2019] [Revised: 02/14/2019] [Accepted: 03/24/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND Hepatic encephalopathy (HE) can adversely affect outcomes in both in-patients and out-patients with cirrhosis. AIM To define targets for improving quality of care in HE management in the multi-centre North American Consortium for End-Stage Liver Disease (NACSELD) cohort. METHOD NACSELD in-patient cohort was analysed for (a) medication-associated precipitants, (b) aspiration pneumonia development, (c) HE medication changes, and (d) 90-day HE recurrence/readmissions. Comparisons were made between patients on no-therapy, lactulose only, rifaximin only or both. Ninety-day HE-readmission analysis was adjusted for MELD score. RESULTS Two thousand eight hundred and ten patients (1102 no-therapy, 659 lactulose, 154 rifaximin, 859 both) were included. HE on admission, and HE rates during hospitalisation were highest in those on lactulose only or dual therapy compared to no-therapy or rifaximin only (P < 0.001). Medications were the most prevalent precipitants (32%; 21% lactulose over/underuse, 5% benzodiazepines, 4% opioids, 1% rifaximin underuse, 1% hypnotics). Patients with medication-associated precipitants had a better prognosis compared to other precipitants. A total of 23% (n = 217) reached grade 3/4 HE, of which 16% developed HE-related aspiration pneumonia. Two thousand four hundred and twenty patients were discharged alive without liver transplant (790 no-therapy, 639 lactulose, 136 rifaximin, 855 both); 12.5% (n = 99) of no-therapy patients did not receive a discharge HE therapy renewal. Ninety-day HE-related readmissions were seen in 16% of patients (9% no-therapy, 9% rifaximin only, lactulose only 18%, dual 21%, <0.001), which persisted despite MELD adjustment (P = 0.009). CONCLUSION Several targets to improve HE management were identified in a large cohort of hospitalised cirrhotic patients. Interventions to decrease medication-precipitated HE, prevention of aspiration pneumonia, and optimisation of HE medications are warranted.

Abstract
Acute-on-chronic liver failure (ACLF) characterized with ≥2 extrahepatic organ failures in cirrhosis carries a high mortality. Outcomes of patients listed for liver transplantation (LT) after ACLF and after LT are largely unknown. The North American Consortium for the Study of End-Stage Liver Disease prospectively enrolled 2793 nonelectively hospitalized patients with cirrhosis; 768 were listed for LT. Within 3 months, 265 (35%) received a LT, 395 remained alive without LT, and 108 died/delisted. Compared with nonlisted patients, those listed were younger and more often had ACLF, acute kidney injury, and a higher admission Model for End-Stage Liver Disease (MELD) score. ACLF was most common in patients who died/delisted, followed by those alive with and without LT respectively, (30%, 22%, and 7%, respectively; P < 0.001). At LT, median MELD was 27.9% and 70% were inpatients; median time from hospitalization to LT was 26 days. Post-LT survival at 6 months was unchanged between those with and without ACLF (93% each at 6 months). There was no difference in 3- and 6-month mean post-LT creatinine in those with and without ACLF, despite those with ACLF having a higher mean pre-LT creatinine and a higher rate of perioperative dialysis (61%). In conclusion, patients with and without ACLF had similar survival after transplant with excellent renal recovery in both groups.

Abstract
Recognizing the importance of timely guidance regarding the rapidly evolving field of hepatitis C management, the American Association for the Study of Liver Diseases (AASLD) and the Infectious Diseases Society of America (IDSA) developed a web-based process for the expeditious formulation and dissemination of evidence-based recommendations. Launched in 2014, the hepatitis C virus (HCV) guidance website undergoes periodic updates as necessitated by availability of new therapeutic agents and/or research data. A major update was released electronically in September 2017, prompted primarily by approval of new direct-acting antiviral agents and expansion of the guidance's scope. This update summarizes the latest release of the HCV guidance and focuses on new or amended recommendations since the previous September 2015 print publication. The recommendations herein were developed by volunteer hepatology and infectious disease experts representing AASLD and IDSA and have been peer reviewed and approved by each society's governing board.

Abstract
UNLABELLED Acute on chronic liver failure (ACLF) is the culmination of chronic liver disease and extrahepatic organ failures, which is associated with a high short-term mortality and immense health care expenditure. There are varying definitions for organ failures and ACLF in Europe, North America, and Asia. These differing definitions need to be reconciled to enhance progress in the field. The pathogenesis of ACLF is multifactorial and related to interactions between the immunoinflammatory system, microbiota, and the various precipitating factors. Individual organ failures related to the kidney, brain, lungs, and circulation have cumulative adverse effects on mortality and are often complicated or precipitated by infections. Strategies to prevent and rapidly treat these organ failures are paramount in improving survival. With the aging population and paucity of organs for liver transplant, the prognosis of ACLF patients is poor, highlighting the need for novel therapeutic strategies. The role of liver transplant in ACLF is evolving and needs further investigation across large consortia. A role for early palliative care and management of frailty as approaches to alleviate disease burden and improve patient-reported outcomes is being increasingly recognized. CONCLUSION ACLF is a clinically relevant syndrome that is epidemic worldwide and requires a dedicated multinational approach focused on prognostication and management; investigations are underway worldwide to prepare ACLF for prime time.

Abstract
Waitlist time for kidney transplantation is long but may be shortened with the utilization of hepatitis C positive allografts. We retrospectively reviewed the course of 36 hepatitis C positive patients awaiting kidney transplantation at 2 large centers within the same health system, with near-identical care delivery models with the exception of timing of hepatitis C treatment, to determine the impact of timing of hepatitis C treatment on access to transplant, waitlist time, and treatment efficacy and tolerability. The majority of patients had hepatitis C genotype 1a or 1b, and all received direct acting antiviral therapy with 100% treatment response. One patient underwent transplantation in the pretransplant treatment group. The 1-year transplantation rate was 12.5% vs 67.9% (P = .0013) in those treated posttransplantation. The median waitlist time in the posttransplant group was 122 (interquartile range [IQR] 21.5, 531.0) days, which was significantly shorter than the center's regional and national wait time. Pathologic review revealed no difference in allograft quality. Overall treatment related adverse events were not different between the 2 groups. A strategy of posttransplant hepatitis C treatment increased access to transplant and reduced waitlist time. Delaying treatment until after transplant did not appear to adversely affect recipients' kidney allograft or overall survival.

Abstract
INTRODUCTION AND AIM Approximately 10%-15% of patients with hepatitis C genotype 1 (HCV GT1) experience virological relapse after all-oral antiviral regimen using simeprevir (SMV) and sofosbuvir (SOF). The efficacy and safety of treating such relapsers using ledipasvir/sofosbuvir (LDV/SOF) with/without ribavirin (RBV) has been limited. OBJECTIVE Report the virological response and safety of LDV/SOF with/without RBV for 12-24 weeks in treating HCV GT1 relapsers after SMV + SOF. MATERIAL AND METHODS Patients treated with standardized clinical protocol utilizing LDV/SOF with/without RBV at three transplant centers were retrospectively reviewed. RESULTS Forty-five patients (29% post-LT, 82% male, 13% non-white, 73% subtype 1a, 86% IL28B CT/TT, 78% F3-4) started LDV/SOF with/without RBV at a median of 22 weeks (range 7-55 weeks) after the last dose of SMV+SOF treatment. Thirty-seven patients received LDV/SOF for 24 weeks (24/37 patients with RBV) and eight patients received LDV/SOF for 12 weeks (5/8 patients with RBV). RBV dose was adjusted for renal function. Sixteen patients who were RBV-ineligible received LDV/SOF without RBV for 12 or 24 weeks. SVR 12 was achieved in 96% (43/45) of patients. Baseline viral load, RBV use, or GT1 subtype did not impact SVR 12. Minimal adverse events were reported in those without RBV; 45% of patients who received RBV developed significant anemia requiring RBV dose reduction and/or discontinuation. In LT recipients, minimal immunosuppression dose adjustments were required and no biopsy-proven acute rejection occurred. CONCLUSIONS Treatment with LDV/SOF with/without RBV for 12-24 weeks was very well tolerated and resulted in high SVR 12 rates (96%) in HCV GT1 relapsers to SMV + SOF treatment.

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.

Abstract
OBJECTIVES Bacterial infections are associated with negative outcomes in cirrhosis but fungal infections are being increasingly recognized. The objective of this study is to define risk factors for fungal infection development and impact on 30-day survival. METHODS In a large, multi-center cirrhotic inpatient cohort, demographics, cirrhosis details, intensive care unit (ICU), organ failures/acute-on-chronic liver failure (ACLF), and 30-day survival were compared between patients without infections and with bacterial infections alone, with those with fungal infections. Variables associated with fungal infection development were determined using multi-variable regression. Ordinal variables (0=no infection, 1=community-acquired bacterial infection, 2=nosocomial bacterial, and 3=fungal infection) were input into a 30-day survival model. RESULTS A total of 2,743 patients (1,691 no infection, 918 bacterial, and 134 fungal infections) were included. Patients with fungal infection, all of which were nosocomial, were more likely to be admitted with bacterial infections, on spontaneous bacterial peritonitis prophylaxis, and have diabetes and advanced cirrhosis. Bacterial infection types did not predict risk for fungal infections. Multi-variable analysis showed male gender to be protective, whereas diabetes, longer stay, ICU admission, acute kidney injury (AKI), and admission bacterial infection were associated with fungal infection development (area under the curve (AUC)=0.82). Fungal infections were associated with significantly higher ACLF, inpatient stay, ICU admission, and worse 30-day survival. The case fatality rate was 30% with most fungal infections but >50% for fungemia and fungal peritonitis. On a multi-variable analysis, age, AKI, model for end-stage liver disease, ICU admission, and ordinal infection variables impaired survival (P<0.0001, AUC=0.83). CONCLUSIONS Fungal infections are associated with a poor 30-day survival in hospitalized cirrhotic patients compared with uninfected patients, and those with bacterial infections. Patients with diabetes, AKI, and those with an admission bacterial infection form a high-risk subgroup.

Abstract
BACKGROUND Glecaprevir and pibrentasvir are direct-acting antiviral agents with pangenotypic activity and a high barrier to resistance. We evaluated the efficacy and safety of 8-week and 12-week courses of treatment with 300 mg of glecaprevir plus 120 mg of pibrentasvir in patients without cirrhosis who had hepatitis C virus (HCV) genotype 1 or 3 infection. METHODS We conducted two phase 3, randomized, open-label, multicenter trials. Patients with genotype 1 infection were randomly assigned in a 1:1 ratio to receive once-daily glecaprevir-pibrentasvir for either 8 or 12 weeks. Patients with genotype 3 infection were randomly assigned in a 2:1 ratio to receive 12 weeks of treatment with either glecaprevir-pibrentasvir or sofosbuvir-daclatasvir. Additional patients with genotype 3 infection were subsequently enrolled and nonrandomly assigned to receive 8 weeks of treatment with glecaprevir-pibrentasvir. The primary end point was the rate of sustained virologic response 12 weeks after the end of treatment. RESULTS In total, 1208 patients were treated. The rate of sustained virologic response at 12 weeks among genotype 1-infected patients was 99.1% (95% confidence interval [CI], 98 to 100) in the 8-week group and 99.7% (95% CI, 99 to 100) in the 12-week group. Genotype 3-infected patients who were treated for 12 weeks had a rate of sustained virologic response at 12 weeks of 95% (95% CI, 93 to 98; 222 of 233 patients) with glecaprevir-pibrentasvir and 97% (95% CI, 93 to 99.9; 111 of 115) with sofosbuvir-daclatasvir; 8 weeks of treatment with glecaprevir-pibrentasvir yielded a rate of 95% (95% CI, 91 to 98; 149 of 157 patients). Adverse events led to discontinuation of treatment in no more than 1% of patients in any treatment group. CONCLUSIONS Once-daily treatment with glecaprevir-pibrentasvir for either 8 weeks or 12 weeks achieved high rates of sustained virologic response among patients with HCV genotype 1 or 3 infection who did not have cirrhosis.

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.

Abstract
GOALS/BACKGROUND Data on acute variceal hemorrhage (AVH) in the United States is limited and the best method to stratify risk is not clear. Taking advantage of a prospective US cohort study, we aimed to (1) describe clinical outcomes of AVH and their predictors; (2) compare predictors of 6-week mortality. STUDY Prospective 15-center US cohort of patients with cirrhosis presenting with endoscopically proven AVH, all of whom received antibiotics, vapreotide (a somatostain analog) infusion and endoscopic band ligation. Patients were enrolled between August 2006 and April 2008. Primary outcome was 6-week mortality. Secondary outcome was 5-day treatment failure. The prognostic value of Child-Turcotte-Pugh (CTP) class, Model for End-stage Liver Disease (MELD) score and a recent recalibrated MELD were compared. RESULTS Seventy eligible patient were enrolled; 18 (26%) patients died within 6-weeks of index bleed. Demographic, clinical, and laboratory data were compared between survivors and nonsurvivors. Multivariate models showed that admission CTP or the MELD score (separately) were independent predictors of survival. The discriminative values of CTP (area under receiver operating characteristic: 0.75) and MELD (area under receiver operating characteristic: 0.79) were good and not significantly different (P=0.27). However, calibration (correlation between observed and predicted mortality) test was significantly better for CTP than for MELD, with the recently described recalibrated MELD model having the worst agreement. Predicted mortality for CTP-A was <10%, CTP-B 10% to 30%; and CTP-C >33%. CONCLUSIONS AVH mortality of 26% in the United States is in the upper range limit compared with recent series but may be due to inclusion of patients with more advanced cirrhosis. CTP score has the best overall performance in the prediction of 6-week mortality and is best at stratifying risk.

Abstract
Approximately 350 million people worldwide are infected with hepatitis C virus (HCV), which is associated with morbidity and mortality related to cirrhosis, hepatocellular carcinoma, or liver failure. Recently, vast improvements have been made with the development of direct-acting antiviral (DAA) agents, which are all-oral, are better tolerated than interferon-based treatment, and provide a sustained virologic response in more than 90% of treated patients. This article reviews the new therapies available for HCV infection, with a focus on patients who have chronic HCV with and without compensated cirrhosis. As DAA development continues, more attention will need to be given to special patient populations, specifically to patients who fail treatment due to emerging resistant strains. Considerable challenges yet to be overcome are incremental diagnosis of unidentified patients and linkage to care that is affordable and available to all patients.

Abstract
BACKGROUND Liver transplant recipients are at increased risk of metabolic complications, including new-onset diabetes mellitus after transplantation (NODAT) and post-transplant metabolic syndrome (PTMS), both of which are associated with decreased patient survival. We prospectively monitored traditional and novel metabolic parameters in nondiabetic liver transplantation (LT) candidates to determine their role in detecting these conditions. METHODS Nondiabetic adults undergoing initial LT were prospectively identified. NODAT and PTMS were defined according to WHO and ATP III criteria. Metabolic measures were collected at pre-LT, 4, and 12 months post-LT. RESULTS Of 49 subjects enrolled, 24.5% were found to be diabetic pre-LT by 2-hr oral glucose tolerance test (OGTT) despite fasting glucose below the diabetic range. Two patients developed NODAT post-LT. A single patient was found to have MS at baseline, while PTMS developed in 26% and 31.3% of patients at 4 and 12 months. Novel metabolic markers did not detect these conditions. CONCLUSIONS Screening OGTT detected pre-LT diabetes in patients with normal fasting glucose. Serial measurement of metabolic parameters allowed earlier detection of PTMS. Novel metabolic parameters did not correspond to post-LT outcomes, but provided a baseline for future study. More frequent and intensive metabolic monitoring appears reasonable, but larger studies are needed to clarify its efficacy.

Effectiveness of Simeprevir Plus Sofosbuvir, With or Without Ribavirin, in Real-World Patients With HCV Genotype 1 Infection. Gastroenterology 2016; 150:419-29. [PMID: 26497081 PMCID: PMC4727992 DOI: 10.1053/j.gastro.2015.10.013] [Citation(s) in RCA: 150] [Impact Index Per Article: 18.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2015] [Revised: 09/10/2015] [Accepted: 10/06/2015] [Indexed: 02/06/2023]
Abstract
BACKGROUND & AIMS The interferon-free regimen of simeprevir plus sofosbuvir was recommended by professional guidelines for certain patients with hepatitis C virus (HCV) genotype 1 infection based on the findings of a phase 2 trial. We aimed to evaluate the safety and efficacy of this regimen in clinical practice settings in North America. METHODS We collected demographic, clinical, and virologic data, as well as reports of adverse outcomes, from sequential participants in HCV-TARGET--a prospective observational cohort study of patients undergoing HCV treatment in routine clinical care settings. From January through October 2014, there were 836 patients with HCV genotype 1 infection who began 12 weeks of treatment with simeprevir plus sofosbuvir (treatment duration of up to 16 weeks); 169 of these patients received ribavirin. Most patients were male (61%), Caucasian (76%), or black (13%); 59% had cirrhosis. Most patients had failed prior treatment with peginterferon and ribavirin without (46%) or with telaprevir or boceprevir (12%). The primary outcome was sustained virologic response (SVR), defined as the level of HCV RNA below quantification at least 64 days after the end of treatment (beginning of week 12 after treatment--a 2-week window). Logistic regression models with inverse probability weights were constructed to adjust for baseline covariates and potential selection bias. RESULTS The overall SVR rate was 84% (675 of 802 patients, 95% confidence interval, 81%-87%). Model-adjusted estimates indicate patients with cirrhosis, prior decompensation, and previous protease inhibitor treatments were less likely to achieve an SVR. The addition of ribavirin had no detectable effects on SVR. The most common adverse events were fatigue, headache, nausea, rash, and insomnia. Serious adverse events and treatment discontinuation occurred in only 5% and 3% of participants, respectively. CONCLUSIONS In a large prospective observational cohort study, a 12-week regimen of simeprevir plus sofosbuvir was associated with high rates of SVR and infrequent treatment discontinuation.

Abstract
UNLABELLED Interferon (IFN)-free regimens are needed to treat hepatitis C virus (HCV) infection. Combined simeprevir (SMV) and sofosbuvir (SOF) with or without ribavirin (RBV) results in high sustained virological response (SVR) rates along with minimal adverse events (AEs) in patients with hepatitis C genotype 1 (HCV GT1). The aim of this study was to report on the virological response, safety, and tolerability of SOF and SMV with or without RBV in compensated and decompensated patients with cirrhosis with HCV GT1 infection. Patients treated with standardized clinical protocol utilizing SMV+SOF with or without RBV at three transplant centers were retrospectively reviewed. A total of 119 patients (61% male, 87% white, 69% subtype 1a, 30% Child-Pugh-Turcott [CPT]-B liver cirrhosis [LC], and 82% were treatment experienced) received treatment and were followed for a median of 38 weeks (range, 12-58). Sustained virological response (SVR) at week 12 (SVR12) was achieved in 78% (92 of 118) of patients (95% confidence interval: 69-85). Lower pretreatment Model for End Stage Liver Disease (MELD) score was a predictor of SVR12 (P = 0.018). Baseline viral load, previous treatment status, RBV use, or GT1 subtype did not impact SVR 12. The majority of patients with SVR12 showed stability or improvement in MELD score. Treatment was very well tolerated with mild degrees of AEs. CONCLUSIONS The regimen of SMV+SOF with or without RBV for 12 weeks was very well tolerated and resulted in high SVR12 rates (78%) in HCV GT1 patients with LC. SVR12 was inversely related to pretreatment MELD. SVR12 had favorable short-term impact on MELD score. Long-term impact on disease stability is yet to be determined. Longer treatment duration or the use of different regimen may still be needed in this population.

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. ClinTrials.gov: NCT01938430.

Abstract
As advances in liver disease continue, including the increasing use of liver transplantation, the endoscopist needs to be familiar with the standards of care and potential complications in the management of the cirrhotic population. This includes both elective endoscopic procedures, such as screening colonoscopies and variceal banding, as well as the acutely bleeding cirrhotic patient. Peri-procedural management and standards of care for acute gastrointestinal hemorrhaging of cirrhotic patients will be emphasized. This article will focus on the plethora of data available to highlight the benefits of endoscopic intervention in the care of patients with liver disease and outline the areas of future emphasis.

Abstract
UNLABELLED Treatment with an all-oral interferon-free antiviral regimen using simeprevir and sofosbuvir with or without ribavirin (RBV) for 12 weeks resulted in high sustained virologic response (SVR) rates along with minimal adverse events in non-liver transplant (LT) patients with hepatitis C virus (HCV) genotype 1 infection. This is the first multicenter report on the efficacy, safety, and tolerability of this regimen in LT recipients. A total of 123 patients (76% male, 74% white, 60% genotype 1a, 30% METAVIR F3-F4, 4% decompensation, 11% cholestatic recurrence, 7% had kidney transplant, and 82% previously failed pegylated interferon/RBV-based regimens) received treatment and were followed for a median of 30 weeks (range 12-53 weeks). The median time from LT to treatment was 32 months (range 2-317 months). Tacrolimus was the primary immunosuppression in 91% of patients. Minimal immunosuppression dose adjustments were required. An SVR 12 weeks after treatment completion (SVR12) was achieved in 90% of patients (95% confidence interval 84%-96%). In patients with genotype 1a infection, the SVR12 rate was significantly lower in those with METAVIR F3-F4 (71%) compared to those with F0-F2 (91%). Half of the patients achieved undetected HCV RNA at treatment week 4, and their SVR12 rate was significantly higher (96%) compared to those with detectable HCV RNA (83%). Treatment was very well tolerated with mild degrees of adverse events, except for one death possibly due to drug-induced lung injury. In the 25 patients who received RBV, 72% developed anemia requiring intervention. CONCLUSION An all-oral interferon-free antiviral regimen using simeprevir and sofosbuvir with or without RBV for 12 weeks was very well tolerated and resulted in excellent SVR12 rates in LT recipients with HCV genotype 1 infection.

Abstract
Sarcopenia, or loss of skeletal muscle mass, is associated with increased mortality and morbidity in liver transplant (LT) candidates. Six-minute walk distance (6MWD) and health-related quality of life (HRQOL) as assessed by short form 36 scores (SF-36) also impact clinical outcomes in these patients. This study explored the relationship between the sarcopenia, 6MWD, and HRQOL in LT candidates. Sarcopenia was evaluated based on skeletal muscle mass index (SMI) quantified from abdominal computed tomography. Patients were followed until death, removal from the wait list or the end of the study period. Two hundred and thirteen patients listed for LT were included. The mean SMI, 6MWD and mean gait speed were 54.3 ± 9.7, 370.5 m and 1 m/s, respectively. Sarcopenia was noted in 22.2% of LT candidates. There was no correlation between sarcopenia, 6MWD, and SF-36 scores. The 6MWD, but not sarcopenia, was an independent predictor of mortality (hazard ratio = 2.1 [0.9-4.7]). In summary, sarcopenia did not emerge as a significant predictor of waitlist mortality and also failed to correlate with either functional capacity or HRQOL in LT candidates. In patients with ESLD awaiting LT, 6MWD appears to be a more useful prognostic indicator than the presence of sarcopenia.
