Limitations

MELD | INR, bilirubin (total), creatinine, sodium | MELD or MELD-Na ≥ 20 predicts high mortality at 30 d, consider corticosteroid therapy | (1) Mortality overestimation with elevated creatinine levels; (2) interpersonal variability of creatinine levels; (3) extrahepatic causes of sodium fluctuations; and (4) does not account for markers of AAH complications other than kidney and liver failure |
Maddrey discriminant function | PT (measured and control), bilirubin (total) | MDF ≥ 32 predicts high mortality at 30 d, consider corticosteroid therapy. Oldest, most commonly used score | (1) AKI and other AAH complications not reflected in MDF; (2) PT use instead of INR; and (3) low specificity |
GAHS | Age, WBC, BUN, bilirubin, PT (measured and control) | GAHS ≥ 9 is in favor of high mortality, helpful for selecting candidates for steroid treatment | (1) Only studied on the British population; and (2) lower sensitivity for short-term mortality compared to MELD/MDF |
ABIC | Age, Bilirubin, INR, PT (measured and control) | Score < 6.71 has high negative predictive value to detect patients with low risk | (1) Not used for deciding on steroid initiation; and (2) low accuracy for predicting mortality in severe group |
Lille score | Age, bilirubin (initial, and day 4 OR day 7), albumin, creatinine, and PT | Lille score ≤ 0.45 at day 7 (or 4) implies good response to corticosteroids | (1) Complex to calculate; (2) uses PT instead of INR; and (3) bias secondary to elevated creatinine levels and interpersonal variability of creatinine |
Alcoholic hepatitis histological score | Histologic features of liver injury | Can be combined with clinical prognostic scores for more accurate mortality risk stratification | (1) Requires liver biopsy (invasive); and (2) static |
MELD: Model for end-stage liver disease; INR: International normalized ratio; BUN: Blood urea nitrogen; AKI: Acute kidney injury; WBC: White blood cells; MDF: Maddrey discriminant function; AAH: Alcohol-associated hepatitis; PT: Prothrombin time; GAHS: Glasgow alcoholic hepatitis score; ABIC: Age-bilirubin-INR-creatinine score.
