Alcoholic hepatitis: Prognosis and treatment

Area of Science:

• Hepatology
• Gastroenterology
• Internal Medicine

Background:

• Alcoholic hepatitis (AH) is the most severe form of alcoholic liver disease, often presenting as acute-on-chronic liver failure.
• Severe AH carries a poor short-term prognosis, necessitating accurate diagnostic and prognostic tools.
• Current diagnosis relies on clinical suspicion and liver biopsy, with a need for non-invasive markers.

Purpose of the Study:

• To review the current understanding of alcoholic hepatitis (AH).
• To highlight the limitations of existing diagnostic and prognostic methods.
• To discuss current and future therapeutic strategies for AH.

Main Methods:

• Review of existing literature on alcoholic hepatitis.
• Analysis of current diagnostic criteria and scoring systems (Maddrey's DF, ABIC, MELD, Glasgow, AHHS).
• Evaluation of current and emerging therapeutic interventions, including medical therapy and liver transplantation.

Main Results:

• Definitive AH diagnosis requires liver biopsy; non-invasive markers are needed.
• Prognostic scoring systems exist, including the recent Alcoholic Hepatitis Histological Score (AHHS).
• First-line therapies (prednisolone, pentoxifylline) have limited efficacy for non-responders, indicating a need for novel treatments.

Conclusions:

• There is a critical need for non-invasive diagnostic markers and effective therapies for alcoholic hepatitis.
• Research into disease drivers and animal models is ongoing.
• Liver transplantation is a curative option for non-responders, but selection criteria require further study.
