Abstract
BACKGROUND The etiology of acute liver failure (ALF) remains one of the most important factors in determining prognosis and predicting outcomes. In a significant proportion of ALF cases, however, the etiology remains unknown and is categorized as indeterminate ALF (IND-ALF). In this study, we summarize findings from patients with IND-ALF from 32 transplant centers across the United States, and we compare laboratory, prognostic, and outcome data for patients with IND-ALF. METHODS Between 1998 and 2019, 3364 adult patients with ALF or acute liver injury (ALI) from 32 liver transplant centers were enrolled in the ALFSG registry. The primary clinical outcome of interest was 21-day transplant-free survival (TFS). RESULTS Of the 3364 patients enrolled in the ALFSG registry, 3.4 % (n = 114) were adjudicated as true indeterminate. On multivariate analysis, patients with a lower bilirubin, lower INR, lack of use of mechanical ventilation and no clinical features of coma at baseline had a higher odds ratio of transplant free survival. The number of deaths were similar between patients with true-IND ALF versus patients with indeterminable ALF (29.8% vs. 27.2%), with almost half of the patients requiring liver transplant (42.1% vs. 45.7%). CONCLUSION We illustrate the poor prognoses that true-IND-ALF and indeterminable ALF carry and the need for emergency liver transplantation in most cases.

Abstract
BACKGROUND AND AIMS Autoimmune hepatitis presenting as acute on chronic liver failure (AIH-ACLF) is a novel entity with limited data on clinical course and management. We assessed outcomes in patients of AIH-ACLF with no extrahepatic organ dysfunction/failure when administered steroids. METHODS In this retrospective analysis, clinical data, laboratory parameters, liver biopsy indices and prognostic scores such as model for end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) scores at baseline were computed for patients with AIH-ACLF and compared across strata of incident infections and transplant-free survival. The primary outcome was 90-day transplant-free survival. Biochemical remission was assessed, and predictors of end points were identified. RESULTS Twenty-nine patients of AIH-ACLF were included with a median follow-up of 4 months. The 90- and 180-day transplant-free survival rates of 55.2 [95% confidence interval (CI): 39.7-76.6]% and 30.2(95% CI: 16.7-54.6)%, respectively, were attained on steroids. Three patients (10.3%) underwent liver transplant while 16 (55.2%) deaths occurred. Infections developed in 12 patients (41.3%), leading to worsening prognostic scores, new onset organ dysfunction/failure and 11 deaths. Seven of ten patients (70%) in the transplant-free survivor group attained biochemical remission on follow-up. The MELD score<24 (sensitivity: 68.4%; specificity: 80%) and CTP<11 (sensitivity: 78.9%; specificity: 90%) had best predictive value for survival, in addition to decrease in the MELD score at 2 weeks (sensitivity: 78.9%; specificity: 70%). CONCLUSION Patients with AIH-ACLF have a morbid disease course despite treatment with steroids. Patients with no extrahepatic organ failure with good baseline prognostic scores may be administered steroids with close monitoring for change in MELD over 2 weeks.

Abstract
OBJECTIVE To study the efficacy and safety of high volume plasma exchange (HVPE) in Wilson disease presenting as acute liver failure (WD-ALF). METHODS An analysis of prospectively collected data of consecutively admitted WD-ALF cases was done and patients were divided into two groups: (i) high volume plasma exchange (HVPE) group- who received HVPE + standard medical therapy (SMT), and (ii) SMT group- received only SMT. Outcome measure was transplant free survival (TFS) at 90 days post enrollment, change in biochemical, hemodynamic parameters & incidence of organ dysfunction in HVPE as compared to SMT group, and HVPE related complications. RESULTS Out of the total 43 cases of WD-ALF reported in the study period, 37 were enrolled (median age 9 years, 62.2% males). All biochemical parameters and prognostic indices except blood ammonia and serum creatinine improved significantly at 72 to 96 hours after enrollment in the HVPE group. Overall, TFS at 90 days was present in 9/19 (47.3%) in HVPE group vs 3/18 (16.6%) in the SMT group (OR 2.84, 95% CI 0.91-8.8, P = .049). Kaplan Meier survival analysis revealed that HVPE group had significantly higher cumulative survival as per the Log Rank test (P = .027); median days of survival was 38 days (IQR 12-63) in HVPE group vs 14 (IQR 5-22) days in SMT group. CONCLUSIONS The present study indicates that in children with WD-ALF, HVPE not only acts as a bridging therapy to LT but may also improve proportion of the cases with TFS.

Abstract
BACKGROUND Risk assessment is important for prognostication and individualized treatment decisions for patients with pulmonary arterial hypertension (PAH). The purpose was (1) to compare contemporary risk assessment tools and (2) to determine the prognostic significance of risk parameters of kidney function and whether they can further improve risk prediction for patients with PAH. METHODS We identified a cohort of treatment-naive patients (n = 211) who received an incident diagnosis of PAH at the University of Ottawa Heart Institute. Using demographics, disease characteristics, and hemodynamic data at diagnosis, we categorized patients as low, intermediate, or high risk according to current European guidelines (European Society of Cardiology [ESC]) and registry to evaluate early and long-term pulmonary arterial hypertension disease management (REVEAL) risk scores. The primary end-point was transplant-free survival (TFS). RESULTS Patients were predominantly women (64.6%) with World Health Organization function Class III symptoms (66.5%). The median TFS was 7.09 years. There was little agreement between ESC- and REVEAL-based risk estimates (weighted kappa = 0.21-0.34). Although both the ESC (log-rank, p = 0.0002) and REVEAL algorithms stratified TFS risk (p < 0.0001), the REVEAL score provided superior discrimination (C-statistic = 0.70 vs 0.59, p = 0.004). Renal function at diagnosis (p < 0.0001) and Δ renal function at 6 months (p < 0.0001) were identified as novel risk parameters and served to reclassify some patients in the intermediate-risk category to a lower or higher risk stratum (p < 0.0001). CONCLUSION REVEAL-based strategies provide superior TFS risk discrimination to ESC/European Respiratory Society-based approaches. However, the classification of intermediate-risk patients varied significantly across tools. We demonstrate the importance of renal function, which further improved the stratification of risk in patients with PAH, particularly in patients who are considered intermediate risk.
