Background Alcohol-associated liver disease is increasing among females with an earlier onset and more severe disease at lower levels of exposure. However, there is paucity of literature regarding sex differences related to alcoholic hepatitis. Methods Hospitalized patients with alcoholic hepatitis were selected from the US Nationwide readmissions database 2019. In this cohort, we evaluated sex differences in baseline comorbidities, alcoholic hepatitis related complications and mortality. A subset of patients with alcoholic hepatitis who were hospitalized between January and June 2019 were identified to study sex differences in 6 month readmission rate, mortality during readmission, and composite of mortality during index hospitalization or readmission. Results Among 112 790 patients with alcoholic hepatitis, 33.3% were female. Female patients were younger [48 (38–57) vs. 49 (39–58) years; both P < 0.001] but had higher rates of important medical and mental-health related comorbidities. Compared with males, females had higher rates of hepatic encephalopathy (11.5% vs. 10.1; P < 0.001), ascites (27.9% vs. 22.5%; P < 0.001), portal hypertension (18.5% vs. 16.4%; P < 0.001), cirrhosis (37.3% vs. 31.9%; P < 0.001), weight loss (19.0% vs. 14.5%; P < 0.001), hepatorenal syndrome (4.4% vs. 3.8%; P < 0.001), spontaneous bacterial peritonitis (1.9% vs. 1.7%; P = 0.026), sepsis (11.1% vs. 9.5%; P < 0.001), and blood transfusion (12.9% vs. 8.7%; P < 0.001). Females had a similar in-hospital mortality rate (4.3%) compared to males (4.1%; P = 0.202; adjusted odds ratio (OR) 1.02, 95% CI (cardiac index) 0.89–1.15; P = 0.994). In the subset of patients (N = 58 688), females had a higher 6-month readmission rate (48.9% vs. 44.9%; adjusted OR 1.12 (1.06–1.18); P < 0.001), mortality during readmission (4.4% vs. 3.2%; OR 1.23 (1.08–1.40); P < 0.01), and composite of mortality during index hospitalization or readmission (8.7% vs. 7.2%; OR 1.15 (1.04–1.27); P < 0.01). Conclusion Compared to their male counterparts, females with alcoholic hepatitis were generally younger but had higher rates of comorbidities, alcoholic hepatitis related complications, rehospitalizations and associated mortality. The greater risks of alcohol-associated liver dysfunction in females indicate the need for more aggressive management.
