Updates in clinical science: Alcohol-related hepatitis.

Alcohol-related hepatitis (AH) is a complex disease associated with numerous unmet needs, particularly in diagnosis and treatment. The epidemiology of AH has evolved in recent years, reflecting changes in alcohol consumption during the COVID-19 pandemic and the increasing incidence of AH following bariatric surgery. Advances have also been made in the non-invasive diagnosis of AH, helping to reduce the need for liver biopsy, as well as in the management of infection. Several novel therapeutic strategies have been evaluated, including faecal microbiota transplantation, IL-1 receptor antagonists, oxysterols, and reduced exposure to corticosteroids or antibiotics. Although the results of these trials have been relatively disappointing, they have helped identify promising directions for future research. In patients with the most severe form of AH, particularly those who do not respond to corticosteroids, several studies have suggested that the indications for early liver transplantation could be expanded. Overall, developments over recent years have generated increased optimism regarding the management of patients with severe AH.
