RESUMO
BACKGROUND: Prior assessments of critical care outcomes in patients with cirrhosis have shown conflicting results. We aimed to provide nationwide generalizable results of critical care outcomes in patients with decompensated cirrhosis. METHODS: This is a retrospective study using the National Inpatient Sample from 2016 to 2019. Adults with cirrhosis who required respiratory intubation, central venous catheter placement or both (n = 12,945) with principal diagnoses including: esophageal variceal hemorrhage (EVH, 24%), hepatic encephalopathy (58%), hepatorenal syndrome (HRS, 14%) or spontaneous bacterial peritonitis (4%) were included. A comparison cohort of patients without cirrhosis requiring intubation or central line placement for any principal diagnosis was included. RESULTS: Those with cirrhosis were younger (mean 58 vs. 63 years, p < 0.001) and more likely to be male (62% vs. 54%, p < 0.001). In-hospital mortality was higher in the cirrhosis cohort (33.1% vs. 26.6%, p < 0.001) and ranged from 26.7% in EVH to 50.6% HRS. Mortality when renal replacement therapy was utilized (n = 1580, 12.2%) was 46.5% in the cirrhosis cohort, compared to 32.3% in other hospitalizations (p < 0.001), and was lowest in EVH (25.7%) and highest in HRS (51.5%). Mortality when cardiopulmonary resuscitation was used was increased in the cirrhosis cohort (88.0% vs. 72.1%, p < 0.001) and highest in HRS (95.7%). CONCLUSIONS: One-third of patients with cirrhosis requiring critical care did not survive to discharge in this U.S. nationwide assessment. While outcomes were worse than in patients without cirrhosis, the results do suggest better outcomes compared to previous studies.

Liver transplantation (LT) is a life-saving treatment for patients with acute liver failure (ALF). Currently, there are few detailed data regarding long-term outcomes after LT for ALF. We combined prospective data from the Acute Liver Failure Study Group (ALFSG) Registry with those of the Scientific Registry of Transplant Recipients (SRTR) to assess outcomes among consecutive patients with ALF listed for LT. Cohort analysis of detailed pretransplantation data for patients listed for LT for ALF in the ALFSG Registry between January 1998 and October 2018 matched with transplantation-related data from the SRTR. Primary outcomes were 1- and 3-year post-LT patient survival. Secondary outcome was receipt of LT; independent associations with successful receipt of LT were determined using multivariable logistic regression. Of 624 patients with ALF listed for LT, 398 (64%) underwent LT, 100 (16%) died without LT, and 126 (20%) recovered spontaneously. Among LT recipients, etiologies included seronegative/indeterminate (22%), drug-induced liver injury (18%), acetaminophen overdose (APAP; 16%), and viral hepatitis (15%). The 1- and 3-year post-LT patient survival rates were 91% and 90%, respectively. Comparing those dying on the waiting list versus with those who received LT, the former had more severe multiorgan failure, reflected by increased vasopressor use (65% vs. 22%), mechanical ventilation (84% vs. 57%), and renal replacement therapy (57% vs. 30%; p < 0.0001 for all). After adjusting for relevant covariates, age (adjusted odds ratio [aOR] 1.02, 95% confidence interval [CI] 1.00-1.04), APAP etiology (aOR 2.72, 95% CI 1.42-5.23), requirement for vasopressors (aOR 4.19, 95% CI 2.44-7.20), Grade III/IV hepatic encephalopathy (aOR 2.47, 95% CI 1.29-4.72), and Model for End-Stage Liver Disease (MELD) scores (aOR 1.05, 95% CI 1.02-1.09; p < 0.05 for all) were independently associated with death without receipt of LT. Post-LT outcomes for ALF are excellent in this cohort of very ill patients. The development of multiorgan failure while on the transplantation list and APAP ALF etiology were associated with a lower likelihood of successful receipt of LT.

RESUMO
Spontaneous survival rates in acute liver failure (ALF) are vastly improved by liver transplantation (LT). However, the value of induction agents beyond steroids continues to be debated. To understand the potential benefit of different induction regimens in the ALF population, we compared overall survival of recipients undergoing LT in the United States for ALF. Using the Scientific Registry of Transplant Recipients, we assessed the impact of induction immunosuppression (IS) in a cohort of 3754 first-time LT recipients with a diagnosis of ALF from 2002 to 2018. Induction IS therapy was grouped into steroid-only induction, use of antithymocyte globulin (ATG), or interleukin 2 receptor antibody. Other regimens were excluded from analysis. Survival analysis was estimated via Cox proportional hazards models and expressed as hazard ratios (HRs). In LT for ALF, the use of induction agents beyond steroids is increasingly frequent over the last 2 decades. The use of ATG is associated with worse overall survival, even after adjusting for donor and recipient factors, with HR of 1.24 (95% confidence interval, 1.00-1.53; P = 0.05). An elevated serum creatinine, recipient and donor age, and Black ethnicity, were all associated with reduced survival, whereas maintenance IS with calcineurin inhibitors (CNIs) was associated with improved survival. Although adjunct induction therapy has become more common, our analysis shows that compared with a steroid-only induction regimen, the addition of ATG is associated with worse overall survival after LT for ALF. CNI maintenance was highly protective, suggesting that an IS strategy focusing on corticosteroid-only induction followed by CNI maintenance may offer the best overall survival rate.

OBJECTIVE: To identify factors that accurately predict 1-year survival for liver transplant recipients with a MELD score ≥40. BACKGROUND: Although transplant is beneficial for patients with the highest acuity (MELD ≥40), mortality in this group is high. Predicting which patients are likely to survive for >1 year would be medically and economically helpful. METHODS: The Scientific Registry of Transplant Recipients database was reviewed to identify adult liver transplant recipients from 2002 through 2016 with MELD score ≥40 at transplant. The relationships between 44 recipient and donor factors and 1-year patient survival were examined using random survival forests methods. Variable importance measures were used to identify the factors with the strongest influence on survival, and partial dependence plots were used to determine the dependence of survival on the target variable while adjusting for all other variables. RESULTS: We identified 5309 liver transplants that met our criteria. The overall 1-year survival of high-acuity patients improved from 69% in 2001 to 87% in 2016. The strongest predictors of death within 1 year of transplant were patient on mechanical ventilator before transplantation, prior liver transplant, older recipient age, older donor age, donation after cardiac death, and longer cold ischemia. CONCLUSIONS: Liver transplant outcomes continue to improve even for patients with high medical acuity. Applying ensemble learning methods to recipient and donor factors available before transplant can predict survival probabilities for future transplant cases. This information can be used to facilitate donor/recipient matching and to improve informed consent.

PURPOSE OF REVIEW: United States has seen several significant changes in liver allocation. The aim of this review is to focus on those changes. RECENT FINDINGS: The success of liver transplantation led to its wider applicability for patients with end-stage liver disease. This success meant ultimately more patients were in need of transplantation, however, there was a limited availability of cadaveric organs. A system of prioritization was critical to reconcile the disparity between supply and demand of organs for liver transplantation. Liver allocation system has continuously evolved since inception. Implementation of the Model for End-Stage Liver Disease (MELD)-system of allocation occurred in 2002. Since then several 'tweaks' have been made to the allocation system. Most recently, United Network for Organ Sharing made significant changes to the liver-allocation policy to promote a broader sharing of livers. This policy eliminates the use of donor service areas (DSAs) and regions, and is consistent with direction given by the US Department of Health and Human Services Final Rule. This policy is awaiting implementation. SUMMARY: An ideal allocation policy would be fair, equitable and significantly reduce the waitlist mortality while simultaneously improving post transplantation outcomes. The impact of the recent changes in liver allocation on landscape of liver transplantation in United States is eagerly awaited.

BACKGROUND & AIMS: Evaluation of patients with acute liver injury (ALI) or acute liver failure (ALF) often includes measurement of plasma levels of acetaminophen, to determine exposure and/or toxicity. However, once liver injury has developed, acetaminophen might be undetectable in plasma. We investigated the association between level of acetaminophen measured and outcomes of patients designated as having ALF or ALI due to acetaminophen toxicity. METHODS: We performed a retrospective analysis of data from 434 subjects in the Acute Liver Failure Study Group who met criteria for ALF (coagulopathy and hepatic encephalopathy within 26 weeks of the first symptoms, without pre-existing liver disease) or ALI (severe liver injury with coagulopathy but no encephalopathy) due to acetaminophen toxicity from January 1, 2010 through December 31, 2014. We collected data on patient demographics, biochemical features, reported acetaminophen use, N-acetylcysteine therapy, liver transplant, and outcomes. Descriptive statistics were used to assess patient demographics, clinical characteristics, and outcomes whereas differences in continuous variables between patients with vs without acetaminophen detection on admission were analyzed using the Wilcoxon rank-sum test. The primary aim was to determine the proportion of patients with detectable plasma levels of acetaminophen. RESULTS: Acetaminophen was undetectable in serum samples from 227 patients (52%). There were no significant differences between groups of patients with detectable vs undetectable levels in demographic features, alcohol use, median levels of alanine aspartate, or use of N-acetylcysteine (given to 94.7% of patients with detectable acetaminophen vs 95.9% of those with undetectable acetaminophen; P=.63). We observed a significant difference in median dose taken between patients with detectable (29,500 mg; interquartile range, 15,000 mg-50,007 mg) vs no detectable parent compound (14,950 mg; interquartile range, 3960 mg-25,000) (P=.003). A lower proportion of patients with detectable plasma levels of acetaminophen (72.3%) survived without a liver transplant than of patients with undetectable levels (86.3%) in univariate analysis (P=.0006), although this was not significant in multivariable analysis (P=.12). Although most patients had unintentional overdoses, a higher proportion of patients with suicidal overdoses (43%) had detectable levels of acetaminophen than patients with accidental overdoses (29.3%; P=.01). CONCLUSION: More than half of patients who present at the hospital with acetaminophen-induced ALI or ALF have undetectable levels of acetaminophen. Clinicians should not exclude acetaminophen toxicity because of undetectable levels or withhold N-acetylcysteine for patients with ALI or ALF when acetaminophen toxicity is suspected.

Background: Nonadherence to antiviral therapy can lead to poor clinical outcomes among patients with chronic hepatitis B (CHB). We used a claims database to evaluate risk factors for nonadherence to antiviral therapy among commercially insured patients with CHB in the United States. Methods: We obtained data for commercially insured adult patients with CHB prescribed entecavir or tenofovir disoproxil fumarate (TDF) in 2019. Primary outcomes were adherence to entecavir and adherence to TDF. Enrollees with a proportion of days covered (PDC) ≥80% were considered adherent. We presented adjusted odds ratios (AORs) from multivariate logistic regressions. Results: Eighty-three percent (n = 640) of entecavir patients were adherent, and 81% (n = 687) of TDF patients were adherent. Ninety-day supply (vs 30-day supply; AOR, 2.21; P < .01), mixed supply (vs 30-day supply; AOR, 2.19; P = .04), and ever using a mail order pharmacy (AOR, 1.92, P = .03) were associated with adherence to entecavir. Ninety-day supply (vs 30-day supply; AOR, 2.51; P < .01), mixed supply (vs 30-day supply; AOR, 1.82; P = .04), and use of a high-deductible health plan (vs no high-deductible health plan; AOR, 2.29; P = .01) were associated with adherence to TDF. Out-of-pocket spending of >$25 per 30-day supply of TDF was associated with reduced odds of adherence to TDF (vs <$5 per 30-day supply of TDF; AOR, 0.34; P < .01). Conclusions: Ninety-day and mixed-duration supplies of entecavir and TDF were associated with higher fill rates as compared with 30-day supplies among commercially insured patients with CHB.
RESUMO
BACKGROUND AND AIMS: Hepatic encephalopathy (HE) is associated with significant morbidity and mortality for those with cirrhosis. Despite the known benefits of rifaximin use for HE, treatment retention remains low. This study aimed to evaluate the impact of out-of-pocket (OOP) rifaximin cost on treatment retention among commercially insured patients in the United States. METHODS: Adult patients with cirrhosis and HE were identified from the IBM MarketScan claims database. Those who began rifaximin treatment between January 1, 2011, and December 1, 2021 were included. Regression models were used to analyze the relationship between patients' 30-day OOP rifaximin cost and rifaximin retention (≥80% eligible days with rifaximin supply) at 180, 360, and 540 days. Models were controlled for patient demographic and clinical characteristics including age, sex, comorbid conditions, Charlson comorbidity index (CCI), and lactulose use. RESULTS: A total of 6839 adult patients were included. Most patients were between 55 and 64 years (57.1%), male (60.4%), and living in urban settings (84.6%). Treatment retention was low for all time periods; retention rates for rifaximin were 42%, 25%, and 16% at 180, 360, and 540 days, respectively. In multivariable analysis, 30-day OOP costs of ≥ $150 were associated with a decreased likelihood of rifaximin retention at 180, 360, and 540 days [relative risk (RR) = 0.67, RR = 0.62, and R = 0.60, respectively]. Younger age was associated with reduced treatment retention for all time periods. Metastatic cancer and depression were associated with reduced treatment retention at 180 days (RR = 0.70 and RR = 0.87, respectively). CONCLUSIONS: Rates of rifaximin treatment retention are low despite the known benefits of rifaximin use for breakthrough HE. High 30-day OOP cost is associated with reduced rifaximin treatment retention.

Treatment modalities for hepatocellular carcinoma (HCC) vary from surgical techniques and interventional radiologic strategies to systemic therapy. For the latter, the use of immune checkpoint inhibitors (ICIs) has gained popularity due to successful trials showing increased survival. In patients who have undergone liver transplantation, recurrence of HCC poses a significant challenge. There is indeed considerable debate on the efficacy and safety of ICI use in liver transplant recipients due to competing immune interests in maintaining a healthy graft and combating the tumor. Recent reports and case series have highlighted a role for the type of immune therapy, timing of therapy, tissue expression of PD-1 and modulation of immunosuppression, in the understanding of the efficacy and risks of ICIs for HCC in liver transplant. In this article, we appraise the available literature on the usage of ICIs for HCC in liver transplant recipients and provide perspectives on immune concerns as well as potential recommendations to consider during the management of such complex cases.
RESUMO
The diagnostic evaluation of an individual with clinical and laboratory evidence of thyroid dysfunction in the setting of acute liver injury is crucial. There is a complex relationship between the thyroid and the liver, and so, it requires a careful elucidation of the inciting disease process before instituting a treatment plan. We discuss a patient who had presented with coagulopathy, encephalopathy, and laboratory evidence of acute liver injury, hence adjudged to have developed drug-induced acute liver failure and transferred for liver transplant evaluation. She was found to have liver dysfunction from uncontrolled thyroid disease, with immediate and rapid improvement after controlling severe hyperthyroidism.
RESUMO
Asparaginase plays an integral role in chemotherapy for acute lymphoblastic leukemia (ALL). We present a 69-year old woman with refractory ALL, who developed asparaginase-induced hepatotoxicity and cholangiopathy after starting intravenous PEG-L-asparaginase-based chemotherapy. The patient was ultimately treated with the combination of L-carnitine and vitamin B complex, resulting in normalization of liver enzymes levels. This case highlights the consideration of PEG-L asparaginase chemotherapy-induced liver steatosis, injury, and cholangiopathy as well as the role of L-carnitine and vitamin B complex as treatment.

Chronic hepatitis B infection is common in the United States, yet only a minority of eligible people are screened, vaccinated, and receive treatment. The Ryan White HIV/AIDS program has been a key tool for ensuring that socioeconomically disadvantaged HIV-infected patients have access to care. Many of the same disease and patient attributes that make the Ryan White program necessary and effective for HIV exist in chronic hepatitis B. Thus, we believe that the current Ryan White program should be expanded to care for people with hepatitis B under similar regulations. Considering recent changes proposed to the health insurance marketplace, policymakers should strongly consider inclusion of chronic hepatitis B in the safety-net Ryan White Program.

Although relatively rare in the United States, acute liver failure (ALF) is associated with very high rates of morbidity and mortality. A leading cause of morbidity and mortality is cerebral edema and intracranial hypertension. Hypothermia, osmotic diuretics, and hyperosmolar therapy are commonly used to manage these complications; however, when these are ineffective, renal replacement therapy may be needed for volume management. Acute kidney injury is a common complication of ALF and may arise from a number of etiologies, including hepatorenal syndrome and acute tubular necrosis. Acute kidney injury is most common in patients who develop ALF because of acetaminophen toxicity or ischemia. With regard to renal replacement therapy, we will review specific considerations relevant to the management of the patient with ALF.
