Insights
Alcoholic hepatitis (AH), a severe liver disease, requires non-invasive markers and novel therapies. Current treatments like steroids are insufficient for many, highlighting the urgent need for research into disease drivers and transplantation criteria.
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.
Abstract:
Alcoholic hepatitis (AH) is a type of acute-on-chronic liver failure and is the most severe form of alcoholic liver disease. AH occurs in patients with heavy alcohol abuse and underlying liver disease. In its severe form, AH carries a poor short-term prognosis. Although the existence of AH can be strongly suspected based on clinical and biochemical criteria, a definitive diagnosis requires a liver biopsy. There is a clear need to develop non-invasive markers for these patients. The prognosis of patients with AH can be established by different score systems (Maddrey's DF, ABIC, MELD and Glasgow). Recently, a histological scoring system able to estimate prognosis has been developed (Alcoholic Hepatitis Histological Score - AHHS). The management of patients with AH has changed little in the last few decades. In patients with severe form of AH, prednisolone and pentoxifylline are the first line therapy. Unfortunately, many patients do not respond and novel targeted therapies are urgently needed. Current research is aimed at identifying the main disease drivers and to develop animal models of true AH. For non-responders to medical therapy, the only curative option is to perform a salvage liver transplantation. This particular indication of liver transplantation is currently under debate and prospective studies should evaluate the specific patient evaluation and selection criteria.
