The incidence of alcoholic hepatitis is difficult to estimate because of inconsistency in diagnosis of the disease and overlap with concurrent, more easily diagnosed liver diseases, such as hepatitis C.1,2 However, hospital admissions for alcoholic hepatitis are on the rise in the United States, accounting for 0.83% of all admissions in 2010.1 Risk factors for the development of the disease include prolonged and heavy alcohol use, younger age, female sex, genetic susceptibility, higher body mass index, and comorbid liver disease.1,35 Overall and in-hospital mortality are high for severe alcoholic hepatitis, with a 28-day mortality rate of 16% to 30% and a one-year mortality rate of 56%.6 The presence of underlying cirrhosis and continued alcohol use negatively impact long-term prognosis.4,79, Because of historical variability in the diagnosis of alcoholic hepatitis, the National Institute on Alcohol Abuse and Alcoholism developed a consensus statement for diagnosing the disease (Table 1).1,7,10 The diagnosis is primarily clinical and must include acute-onset jaundice, specific laboratory abnormalities, and characteristic history of alcohol use (i.e., long-term consumption of roughly three standard drinks daily for women and four standard drinks daily for men). Discriminant function = 4.6 x (PTa - PTc) + Bili. Maddrey score = 4.6 X (prolongation of prothrombin time above control in seconds) + Total bilirubin in mg/dl To calculate Maddrey discriminant function using SI units - micromol/l (i.e. Interpretation: Its caused from drinking too much alcohol.
