An international, multicenter, survey-based analysis of practice and management of acute liver failure.

Acute liver failure (ALF) is an acute liver dysfunction with coagulopathy and HE in a patient with no known liver disease. As ALF is rare and large clinical trials are lacking, the level of evidence regarding its management is low-moderate, favoring heterogeneous clinical practice. In this international multicenter survey study, we aimed to investigate the current practice and management of patients with ALF. An online survey targeting physicians who care for patients with ALF was developed by the International Liver Transplantation Society ALF Special-Interest Group. The survey focused on the management and liver transplantation (LT) practices of ALF. Survey questions were summarized overall and by geographic region. A total of 267 physicians completed the survey, with a survey response rate of 21.36%. Centers from all continents were represented. More than 90% of physicians specialized in either transplant hepatology/surgery or anesthesiology/critical care. Two hundred fifty-two (94.4%) respondents' institutions offered LT. A total of 76.8% of respondents' centers had a dedicated liver-intensive or transplant-intensive care unit ( p < 0.001). The median time to LT was within 48 hours in 12.7% of respondents' centers, 72 hours in 35.6%, 1 week in 37.6%, and more than 1 week in 9.6% ( p < 0.001). Deceased donor liver graft (49.6%) was the most common type of graft offered. For consideration of LT, 84.8% of physicians used King's College Criteria, and 41.6% used Clichy Criteria. Significant differences were observed between Asia, Europe, and North America for offering LT, number of LTs performed, volume of patients with ALF, admission to a dedicated intensive care unit, median time to LT, type of liver graft, monitoring HE and intracranial pressure, management of coagulopathy, and utilization of different criteria for LT. In our study, we observed significant geographic differences in the practice and management of ALF. As ALF is rare, multicenter studies are valuable for identifying global practice.

Brain Abscess Secondary to Streptococcus Intermedius Following an EGD with Biopsy in a Patient with Eosinophilic Esophagitis.

Brain abscess is a rare complication of esophagogastro- duodenoscopy (EGD) with few reported cases in the literature. In this report, we discuss a patient presenting with altered mental status, headache, and dysarthria due to brain abscess caused by S. intermedius shortly after an EGD with an esophageal biopsy showing a new diagnosis of eosinophilic esophagitis. We highlight the rare association of EGD and brain abscess, and discuss the importance of prompt diagnosis and treatment.

A Longitudinal Analysis of Mortality Related to Chronic Viral Hepatitis and Hepatocellular Carcinoma in the United States.

(1) Background: Hepatocellular carcinoma (HCC) contributes to the significant burden of cancer mortality in the United States (US). Despite highly efficacious antivirals, chronic viral hepatitis (CVH) remains an important cause of HCC. With advancements in therapeutic modalities, along with the aging of the population, we aimed to assess the contribution of CVH in HCC-related mortality in the US between 1999-2020. (2) Methods: We queried all deaths related to CVH and HCC in the multiple-causes-of-death files from the CDC Wide-ranging Online Data for Epidemiologic Research (WONDER) database between 1999-2020. Using the direct method of standardization, we adjusted all mortality information for age and compared the age-adjusted mortality rates (AAMRs) across demographic populations and by percentile rankings of social vulnerability. Temporal shifts in mortality were quantified using log-linear regression models. (3) Results: A total of 35,030 deaths were identified between 1999-2020. The overall crude mortality increased from 0.27 in 1999 to 8.32 in 2016, followed by a slight reduction to 7.04 in 2020. The cumulative AAMR during the study period was 4.43 (95% CI, 4.39-4.48). Males (AAMR 7.70) had higher mortality rates compared to females (AAMR 1.44). Mortality was higher among Hispanic populations (AAMR 6.72) compared to non-Hispanic populations (AAMR 4.18). Higher mortality was observed in US counties categorized as the most socially vulnerable (AAMR 5.20) compared to counties that are the least socially vulnerable (AAMR 2.53), with social vulnerability accounting for 2.67 excess deaths per 1,000,000 person-years. (4) Conclusions: Our epidemiological analysis revealed an overall increase in CVH-related HCC mortality between 1999-2008, followed by a stagnation period until 2020. CVH-related HCC mortality disproportionately affected males, Hispanic populations, and Black/African American populations, Western US regions, and socially vulnerable counties. These insights can help aid in the development of strategies to target vulnerable patients, focus on preventive efforts, and allocate resources to decrease HCC-related mortality.

Recipient Survival among Living Donor vs. Deceased Donor Liver Transplants for Acute Liver Failure in the United States.

Objectives: Acute liver failure (ALF) is associated with high morbidity and mortality. Timely liver transplantation (LT) is the only universally accepted therapy for ALF that is non-responsive to medical therapy. Data regarding the use of living donor LT (LDLT) for this indication in the US is scarce. Materials and Methods: United Network of Organ Sharing/Organ Procurement and Transplantation Network (UNOS/OPTN) data from January 2002 to December 2020 were reviewed. Adult and pediatric recipients listed as status 1 were included. Demographics, clinical and laboratory data, and post-LT survival rates were compared for LDLT vs. DDLT recipients. Results: There were 180 LDLT (3.6%) and 4779 DDLT (96.4%) recipients with a diagnosis of ALF. The majority of recipients in the LDLT group were pediatric (n = 164, 91%) compared to the DDLT group (n = 1455, 30%), p < 0.001. In the pediatric-only group, post-LT survival was comparable between LDLT and DDLT recipients (p = 0.15). Five-year post-LT survival was higher for pediatric recipients compared to adults in the LDLT group (84.2% vs. 62.5%, respectively, p < 0.001) and the DDLT group (82.8% vs. 78.7%, respectively, p < 0.001). Adults had a higher hazard of death compared to pediatric recipients in the LDLT group (HR = 3.560, 95% CI 1.612-7.844, p = 0.002) and the DDLT group (HR = 1.472, 95% CI 1.290-1.679, p < 0.001). In multivariate analysis results, the type of LT and age group were not associated with higher post-LT mortality. Conclusions: In the US, LDLT constitutes 3.6% of LTs for ALF. In the pediatric-only group, post-LT survival was comparable between LDLT and DDLT recipients. Overall, there were superior post-LT outcomes for pediatric recipients compared to adults for LDLT and DDLT.
