The Alcoholic Hepatitis Score (AHS) is a clinically significant measure used to determine the severity of alcoholic hepatitis, a condition characterized by inflammation and damage to the liver caused by excessive alcohol consumption. This tutorial provides an in-depth discussion of the Alcoholic Hepatitis Score, its associated calculations and formulas, its relevance in various fields, and the significant achievements related to this topic.

Alcoholic hepatitis is a major global health issue. While the disease's exact prevalence is unknown, an estimated 10-35% of heavy drinkers develop alcoholic hepatitis. Severity can vary, and in its most severe form, alcoholic hepatitis can be life-threatening.
The Alcoholic Hepatitis Score is calculated using several clinical measures, including age, bilirubin, international normalized ratio (INR), creatinine, and presence of hepatic encephalopathy. The general formula is as follows:
AHS = 4.6 × (prolongation of prothrombin time) + 1.53 × (Loge(bilirubin mg/dL)) + 0.66 × (Is hepatic encephalopathy present? Yes=1, No=0) + 0.8
This is known as the Maddrey's Discriminant Function (MDF). A score above 32 is usually indicative of severe alcoholic hepatitis and has been associated with a poor prognosis.
Apart from hepatology, the AHS is significant in broader clinical settings, insurance, and public health. Clinicians of various specialties use it to assess disease severity, inform treatment decisions, and evaluate prognosis. Insurers may use the information in assessing policies for life or health insurance. In public health, understanding the severity and distribution of alcoholic hepatitis can help formulate policies and interventions to mitigate alcohol-related harm.
For example, in a clinical setting, a 40-year-old patient may present with alcoholic hepatitis. Their lab results show bilirubin levels of 10 mg/dL, INR of 1.5, creatinine of 1.0 mg/dL, and no hepatic encephalopathy. Their MDF score would be calculated, and the results would be used to guide further management of their condition.
Notably, Dr. Thomas Maddrey significantly contributed to this field by developing the Maddrey's Discriminant Function in 1978. His work has since been instrumental in diagnosing and managing alcoholic hepatitis, improving the prognosis and quality of life for many patients.
