Introduction The prevalence and significance of acute liver injury in patients with COVID-19 are poorly characterized. Methods Patients with confirmed COVID-19 who were hospitalized in geographically diverse medical centers in North America were included. Demographics, symptoms, laboratory data results, and outcomes were recorded. Linear and logistic regression identified factors associated with liver injury, in-hospital mortality, and length of stay (LOS). Results Among 1555 patients in the cohort, most (74%) had an elevated alanine aminotransferase (ALT) during hospitalization, which was very severe (> 20 × upper limit of normal [ULN]) in 3%. Severe acute liver injury (ALI) was uncommon, occurring in 0.1% on admission and 2% during hospitalization. No patient developed acute liver failure (ALF). Higher ALT was associated with leukocytosis (per mL 3 ) (β 10.0, 95% confidence interval (CI) 6.7–12.6, p < 0.001) and vasopressors use (β 80.2, 95%CI 21.5–138.8, p = 0.007). In-hospital mortality was associated with ALT > 20 × ULN (unadjusted OR 6.0, 95%CI 3.1–11.5, p < 0.001), ALP > 3 × ULN (unadjusted OR 4.4, 95%CI 2.5–7.7, p < 0.001), and severe ALI (unadjusted OR 6.8, 95%CI 3.0–15.3, p < 0.001) but lost significance after adjusting for covariates related to severe COVID-19 and hemodynamic instability. Elevated ALP and ALT were associated with longer LOS, admission to intensive care, mechanical ventilation, vasopressor use, and extracorporeal membrane oxygenation use ( p < 0.001). Conclusions Transaminase elevation is common in hospitalized patients with COVID-19. Severe ALI is rare, and ALF may not be a complication of COVID-19. Extreme elevations in liver enzymes appear to be associated with mortality and longer LOS due to more severe systemic disease rather than SARS-CoV-2-related hepatitis.

Background and Aim Geographic differences have existed in the management of hepatocellular carcinoma (HCC), and efforts to reduce regional disparities have been initiated. The aim of this study is to use the Nationwide Inpatient Sample to determine if regional disparities in the treatment of HCC continue to exist. Method A retrospective database analysis using the Nationwide Inpatient Sample was performed that included patients with a primary diagnosis of HCC. Logistic regression models were utilized to determine geographic disparities in liver decompensation, treatment, inpatient mortality, and metastatic disease. Results This study's locational reach of 62 604 patients included 22 769 patients from the South (36%), 14 554 in the Northeast (23%), 14 041 in the West (22%), and 11 240 in the Midwest (18%). Patients who received treatment in the West were more likely to have inpatient mortality (OR 1.28, 95% CI 1.03, 1.53) than patients who received treatment in the Midwest. No significant differences were observed between rates of resection, ablation, and transarterial chemoembolization when comparing by region. Rates of liver transplantation were lower in the West compared with the Midwest (OR 0.51, 95% CI 0.29, 0.87). There was no significant difference between other regions. Conclusion Geographic disparities in the treatment of HCC are improving.

AIMTo evaluate disparities in the treatment of hepatocellular carcinoma (HCC) based on gender.METHODSA retrospective database analysis using the Nationwide Inpatient Sample (NIS) was performed between 2010 and 2013. Adult patients with a primary diagnosis of hepatocellular carcinoma determined by International Classification of Disease 9 (ICD-9) codes were included. Univariate analysis and multivariate logistic regressions were performed to analyze differences in treatment, mortality, features of decompensation, and metastatic disease based on the patient’s gender.RESULTSThe analysis included 62582 patients with 45908 men and 16674 women. Women were less likely to present with decompensated liver disease (OR = 0.84, P < 0.001) and had less risk of inpatient mortality when compared to men (OR = 0.75, P < 0.001). Women were more likely to receive inpatient resection (OR = 1.31, P < 0.001) or an ablation (OR = 1.22, P = 0.028) than men. There was no significant difference between men and women in regard to liver transplantation and transcatheter arterial chemoembolization (TACE).CONCLUSIONGender impacts treatment for hepatocellular carcinoma. Women are more likely to undergo an ablation or resection then men. Gender disparities in transplantation have resolved.
