Stratification and selection of therapies to improve survival in severe alcoholic hepatitis.

Severe alcoholic hepatitis (SAH) is associated with high short-term mortality. The SAH population exhibits extreme heterogeneity in disease severity, clinical presentation, decompensations, and outcomes. Nonetheless, improving outcomes and preventing adverse events is a major challenge when selecting an appropriate treatment for alcoholic hepatitis. Currently, steroids are the standard of care for SAH with Maddrey's discriminant function > 32 and model for end stage liver disease > 20; however, they have limited usage due to ineligibility in approximately two-third of such patients. Approximately 25% of patients do not respond to steroids and require alternative therapies. An array of evolving therapies, such as granulocyte colony-stimulating factors, plasma exchange, fecal microbiota transplantation, antibiotics, anti-cytokine therapies, and N-acetylcysteine, showing variable success, are emerging. Hence, it is also crucial to select appropriate therapy. The present review discusses the standard of care, the existing therapies, risk stratification for outcomes, and the selection of appropriate therapy to improve survival in SAH patients.
