RESUMO

BACKGROUND & AIMS: Although liver transplantation (LT) has been demonstrated to provide survival benefit for patients with acute-on-chronic liver failure (ACLF), data are lacking regarding resource utilization for this population after LT. METHODS: We retrospectively reviewed data from 10 centers in North America of patients transplanted between 2018 and 2019. ACLF was identified by using the European Association for the Study of the Liver-Chronic Liver Failure criteria. RESULTS: We studied 318 patients of whom 106 patients (33.3%) had no ACLF, 61 (19.1%) had ACLF-1, 74 (23.2%) had ACLF-2, and 77 (24.2%) had ACLF-3 at transplantation. Healthcare resource utilization after LT was greater among recipients with ACLF compared with patients without ACLF regarding median post-LT length of hospital stay (LOS) (P < .001), length of post-LT dialysis (P < .001), discharge to a rehabilitation center (P < .001), and 30-day readmission rates (P = .042). Multivariable negative binomial regression analysis demonstrated a significantly longer LOS for patients with ACLF-1 (1.9 days; 95% confidence interval [CI], 0.82-7.51), ACLF-2 (6.7 days; 95% CI, 2.5-24.3), and ACLF-3 (19.3 days; 95% CI, 1.2-39.7), compared with recipients without ACLF. Presence of ACLF-3 at LT was also associated with longer length of dialysis after LT (9.7 days; 95% CI, 4.6-48.8) relative to lower grades. Multivariable logistic regression analysis revealed greater likelihood of discharge to a rehabilitation center among recipients with ACLF-1 (odds ratio [OR], 1.79; 95% CI, 1.09-4.54), ACLF-2 (OR, 2.23; 95% CI, 1.12-5.01), and ACLF-3 (OR, 2.23; 95% CI, 1.40-5.73). Development of bacterial infection after LT also predicted LOS (20.9 days; 95% CI, 6.1-38.5) and 30-day readmissions (OR, 1.39; 95% CI, 1.17-2.25). CONCLUSIONS: Patients with ACLF at LT, particularly ACLF-3, have greater post-transplant healthcare resource utilization.

RESUMO

Although liver transplantation (LT) yields survival benefit for patients with acute-on-chronic liver failure grade 3 (ACLF-3), knowledge gaps remain regarding risk factors for post-LT mortality. We retrospectively reviewed data from 10 centers in the United States and Canada for patients transplanted between 2018 and 2019 and who required care in the intensive care unit prior to LT. ACLF was identified using the European Association for the Study of the Liver-Chronic Liver Failure (EASL-CLIF) criteria. A total of 318 patients were studied, of whom 106 (33.3%) had no ACLF, 61 (19.1%) had ACLF-1, 74 (23.2%) had ACLF-2, and 77 (24.2%) had ACLF-3 at transplantation. Survival probability 1 year after LT was significantly higher in patients without ACLF (94.3%) compared with patients with ACLF (87.3%; P = 0.02), but similar between ACLF-1 (88.5%), ACLF-2 (87.8%), and ACLF-3 (85.7%; P = 0.26). Recipients with ACLF-3 and circulatory failure (n = 29) had similar 1-year post-LT survival (82.3%) compared with patients with ACLF-3 without circulatory failure (89.6%; P = 0.32), including those requiring multiple vasopressors. For patients transplanted with ACLF-3 including respiratory failure (n = 20), there was a trend toward significantly lower post-LT survival (P =  0.07) among those with respiratory failure (74.1%) compared with those without (91.0%). The presence of portal vein thrombosis (PVT) at LT for patients with ACLF-3 (n = 15), however, yielded significantly lower survival (91.9% versus 57.1%; P < 0.001). Multivariable logistic regression analysis revealed that PVT was significantly associated with post-LT mortality within 1 year (odds ratio, 7.3; 95% confidence interval, 1.9-28.3). No correlation was found between survival after LT and the location or extent of PVT, presence of transjugular intrahepatic portosystemic shunt, or anticoagulation. LT in patients with ACLF-3 requiring vasopressors yields excellent 1-year survival. LT should be approached cautiously among candidates with ACLF-3 and PVT.

RESUMO

PURPOSE: Needs, risks, and outcomes of patients admitted to a post liver transplant intensive care unit (POLTICU) differ in important ways from those admitted to pretransplant intensive care units (ICUs). The aim of this study was to create the optimal model to risk stratify POLTICU patients. METHODS: Consecutive patients who underwent first deceased donor liver transplantation (LT) at a large United States center between 2008 and 2014 were followed from admission to LT and to discharge or death. Receiver-operating characteristic analysis was performed to assess the value of various scores in predicting in-hospital mortality. A predictive model was developed using logistic regression analysis. RESULTS: A total of 697 patients underwent LT, and 3.2% died without leaving the hospital. A model for in-hospital mortality was derived from variables available within 24 hours of admission to the POLTICU. Key variables best predicting survival were white blood cell count, 24-hour urine output, and serum glucose. A model using these variables performed with an area under the curve (AUC) of 0.88, compared to the Acute Physiology and Chronic Health Evaluation III and Model for End-Stage Liver Disease, which performed with AUCs of 0.74 and 0.60, respectively. CONCLUSION: An improved model, the early mortality after LT (EMALT) score, performs better than conventional models in predicting in-hospital mortality after LT.

RESUMO

This multi-center retrospective study examined the effect of weight loss on the prevention of progression to cirrhosis in a sample exclusively composed of patients with obesity and MASH-related F3 liver fibrosis. Adult patients with obesity and biopsy-confirmed MASH-related F3 liver fibrosis (n = 101) from two liver transplant centers in the US were included in the study. A higher proportion of patients who did not progress to cirrhosis achieved >5% weight loss at follow-up (59% vs. 30%, p = 0.045). In multivariable analysis, patients with >5% weight loss at follow-up had a lower hazard of developing cirrhosis compared to patients with no weight loss or weight gain (HR: 0.29, 95%, CI: 0.08-0.96); whereas, diabetes (HR: 3.24, 95%, CI: 1.21-8.67) and higher LDL levels (HR: 1.02, 95%, CI: 1.01-1.04) were associated with higher hazards of progression to cirrhosis. Weight loss >5% has the potential to prevent disease progression to cirrhosis in patients with obesity and MASH-related F3 liver fibrosis. The realization of this benefit requires weight loss maintenance longer than one year. Larger prospective studies are needed to determine how weight loss impacts other patient-centered outcomes such as mortality, hepatic decompensation, and hepatocellular carcinoma in patients with obesity and MASH-related F3 liver fibrosis.

RESUMO

Sustained virological response (SVR) to the treatment of recurrent HCV in liver transplant recipients has excellent clinical outcomes; however, little is known about the effects on allograft histology. The study aimed to assess the histology of the allograft liver. In this single-center, retrospective cohort study, patients with recurrent hepatitis C (HCV) in allograft liver who were cured with antiviral therapy between 2010 and 2016 were identified. Biopsies were reviewed by two liver pathologists blinded to the treatment and SVR status. Paired analysis was performed to compare pre- and post-treatment histological features. Of the 62 patients analyzed, 22 patients received PEGylated interferon/ribavirin (IFN) therapy, while 40 patients received direct-acting antiviral agents (DAA). The mean age was 57 years, 24% were female, and 79% were Caucasian. RNA in situ hybridization testing for HCV and HEV was negative in all the tested patients. Significant reduction in the inflammatory grade of post-treatment biopsy specimens was noted in all subjects (n = 57; p < 0.001) and in the IFN group (n = 21; p = 0.001) but not in the DAA group (p = 0.093). Of all subjects, 21% had worsening stage, 31% had improvement, and 48% had no change in stage. Of the treatment groups, 27% in the IFN and 17% in the DAA groups had worsening stage; however, the results were not statistically significant in all subjects or by treatment modality. Persistent inflammatory infiltrates and fibrosis was noted in allograft tissue of patients cured with DAA. Significant improvement in grade was noted in the IFN group, without a significant change in stage.

RESUMO

BACKGROUND: There is limited data on the use of anti-TNF agents in patients with concomitant cirrhosis. The aim of this study is to assess the safety of anti-TNF agents in patients with compensated cirrhosis who used these medications for the treatment of an underlying rheumatologic condition or IBD. METHODS: Multicenter, retrospective, matched, case-control study. A one to three case-control match was performed. Adults who received anti-TNF therapy were matched to three adults with cirrhosis who did not receive anti-TNF therapy. Patients were matched for etiology of cirrhosis, MELD-Na and age. Primary outcome was the development of hepatic decompensation. Secondary outcomes included development of infectious complications, hepatocellular carcinoma (HCC), extra-hepatic malignancy, and mortality. RESULTS: Eighty patients with cirrhosis who received anti-TNF agents were matched with 240 controls. Median age was 57.2 years. Median MELD-Na for the anti-TNF cohort was seven and median MELD-Na for the controls was eight. The most common etiology of cirrhosis was NAFLD. Anti-TNF therapy did not increase risk of decompensation (HR: 0.91, 95% CI: 0.64-1.30, p = 0.61) nor influence the time to development of a decompensating event. Anti-TNF therapy did not increase the risk of hepatic mortality or need for liver transplantation (HR: 1.18, 95% CI: 0.55-2.53, p = 0.67). Anti-TNF therapy was not associated with an increased risk of serious infection (HR: 1.21, 95% CI: 0.68-2.17, p = 0.52), HCC (OR: 0.45, 95% CI: 0.13-1.57, p = 0.21), or extra-hepatic malignancy (OR: 0.82, 95% CI: 0.29-2.30, p = 0.71). CONCLUSIONS: Anti-TNF agents in patients with compensated cirrhosis does not influence the risk of decompensation, serious infections, transplant free survival, or malignancy.

RESUMO

OBJECTIVE: Hepatitis B reactivation (HBr) is strongly associated with rituximab therapy. Guidelines advise hepatitis B screening and use of preventive nucleoside analogue (NA) in patients at risk. In this study, we examined screening trends, post-screening interventions and outcomes in patients receiving rituximab in light of recommendations. DESIGN: Retrospective, observational study. SETTING: Single, tertiary care centre in the USA. PARTICIPANTS: Patients receiving rituximab from January 2005 to December 2017. PRIMARY OUTCOME: Trends of hepatitis B screening prior to initiation of rituximab. SECONDARY OUTCOME: Results of hepatitis B screening, use of preventive NA therapy and HBr incidence. RESULTS: Over 13 years, 2219 patients received rituximab. Screening, with at least hepatitis B core antibody (anti-HBc) prior to the first dose of rituximab, improved from 20% to 97%. Because only 4.5% of patients had a positive anti-HBc, the overall HBr incidence was very low (0.42%). In susceptible patients, the incidence of HBr was 8%. In at-risk patients given preventive NA, 96% remained free of HBr. However, only 23% received a preventive NA and no temporal improvement in compliance was seen. Of those with HBr, 87.5% were hepatitis B surface antigen (HbsAg-)/anti-HBc+. CONCLUSIONS: In those treated with rituximab, we demonstrated near-universal anti-HBc screening. Screening unlinked to preventive NA use, in those who are anti-HBc+, is ineffective in reducing HBr. HBr has a high fatality rate. The majority of cases occurred in those who were HBsAg negative. Efforts are needed to educate providers who use rituximab not only to screen for anti-HBc, but to provide preventive NA to those who test positive.

RESUMO

BACKGROUND: Critically ill patients with cirrhosis, particularly those with acute decompensation, have higher mortality rates in the intensive care unit (ICU) than patients without chronic liver disease. Prognostication of short-term mortality is important in order to identify patients at highest risk of death. None of the currently available prognostic models have been widely accepted for use in cirrhotic patients in the ICU, perhaps due to complexity of calculation, or lack of universal variables readily available for these patients. We believe a survival model meeting these requirements can be developed, to guide therapeutic decision-making and contribute to cost-effective healthcare resource utilization. AIM: To identify markers that best identify likelihood of survival and to determine the performance of existing survival models. METHODS: Consecutive cirrhotic patients admitted to a United States quaternary care center ICU between 2008-2014 were included and comprised the training cohort. Demographic data and clinical laboratory test collected on admission to ICU were analyzed. Area under the curve receiver operator characteristics (AUROC) analysis was performed to assess the value of various scores in predicting in-hospital mortality. A new predictive model, the LIV-4 score, was developed using logistic regression analysis and validated in a cohort of patients admitted to the same institution between 2015-2017. RESULTS: Of 436 patients, 119 (27.3%) died in the hospital. In multivariate analysis, a combination of the natural logarithm of the bilirubin, prothrombin time, white blood cell count, and mean arterial pressure was found to most accurately predict in-hospital mortality. Derived from the regression coefficients of the independent variables, a novel model to predict inpatient mortality was developed (the LIV-4 score) and performed with an AUROC of 0.86, compared to the Model for End-Stage Liver Disease, Chronic Liver Failure-Sequential Organ Failure Assessment, and Royal Free Hospital Score, which performed with AUROCs of 0.81, 0.80, and 0.77, respectively. Patients in the internal validation cohort were substantially sicker, as evidenced by higher Model for End-Stage Liver Disease, Model for End-Stage Liver Disease-Sodium, Acute Physiology and Chronic Health Evaluation III, SOFA and LIV-4 scores. Despite these differences, the LIV-4 score remained significantly higher in subjects who expired during the hospital stay and exhibited good prognostic values in the validation cohort with an AUROC of 0.80. CONCLUSION: LIV-4, a validated model for predicting mortality in cirrhotic patients on admission to the ICU, performs better than alternative liver and ICU-specific survival scores.

RESUMO

Background and Aims: Hepatitis C virus (HCV)-infected organs are underutilized. We aimed to assess the safety and efficacy of direct-acting antiviral agents (DAAs) therapy in HCV viremic patients who are transplanted with a liver from a HCV viremic donor. Methods: We conducted a retrospective study, including patients seen from July 2015 to April 2017. HCV viremic patients transplanted with a liver from a HCV viremic donor and subsequently treated with DAAs were included. Outcomes assessed included undetectable viral load at 12 weeks after completing DAA therapy (sustained virologic response, SVR12), adverse events, and interactions with immunosuppression. Results: Twenty-four HCV viremic recipients received livers from HCV viremic donors. Median age was 63 years, and the majority (79.2%) were genotype 1a. Donors and recipients were viremic at the time of transplant. Median modified model for end-stage liver disease score was 19, and median time on the waitlist was 81 days. Median time from transplant to initiation of DAA therapy was 123 days. Several DAA regimens were used and 15 (62.5%) patients did not receive ribavirin. Treatment duration ranged from 12 to 24 weeks. Twenty-three (95.8%) patients achieved SVR12. Five (20.8%) patients developed adverse events; however, none required DAA discontinuation. Conclusions: DAA therapy was efficacious and well tolerated in HCV viremic recipients who underwent liver transplantation from a HCV viremic donor.

RESUMO

Vedolizumab is a humanized monoclonal α4ß7 integrin antibody used in patients with Crohn's disease (CD) and ulcerative colitis (UC). Limited data are available on the use of vedolizumab in patients with concurrent cirrhosis and inflammatory bowel disease (IBD). Patients with cirrhosis are unique, as they have a predilection for developing opportunistic infections and malignancies. Additionally, it is not known if vedolizumab alters the natural course of cirrhosis. We report our experience in three patients with concomitant CD and cirrhosis, who were treated with vedolizumab. In our limited cohort, all the three patients tolerated vedolizumab well. None of them experienced significant infectious complications, nor did any have decompensated cirrhosis. Our limited series suggest that vedolizumab is well tolerated in patients with compensated cirrhosis.
