Determinants of Short- and Long-Term Outcomes of an Australian Cohort of Patients Admitted with Alcoholic Hepatitis.

Abstract

Alcoholic hepatitis is a common condition with high mortality. This study aimed to firstly describe the presentation, treatment, and short- and long-term outcomes of an Australian cohort of patients admitted to hospital with alcoholic hepatitis and secondly to validate existing prognostic models. This is a retrospective study of consecutive patients admitted with alcoholic hepatitis to a major academic liver center in Melbourne, Australia, between January 1, 2010, and December 31, 2019. Cases were identified through appropriate International Classification of Diseases version 10 coding as well as review of non-coded patients with compatible biochemistry. Baseline demographic data, alcohol consumption, laboratory values, treatment, and outcomes at 30days, 90days, and 12months post-diagnosis were collected from electronic medical records. Mortality data were extracted from an independent state government death registry. In total, 126 patients (72 males [57%], median age 51years) were included in the final analysis. Ninety-five (75%) were cirrhotic at diagnosis, 81 (64%) met criteria for severe alcoholic hepatitis, and 41 (33%) had an infection during their index admission. 54% of eligible patients were treated with corticosteroids. 30-day and 12-month mortality rates were 8.7% and 27.1%, respectively, with hepatic encephalopathy (hazard ratio 5.45) and neutrophil-to-lymphocyte ratio (hazard ratio 1.09) independent markers for 12-month mortality on Cox regression analysis. Glasgow alcoholic hepatitis score outperformed other major prognostic models for short-term mortality. The 12-month mortality rate of 27% following alcoholic hepatitis is lower than previously reported studies, with hepatic encephalopathy and neutrophil-to-lymphocyte ratio predictive of long-term outcome.
