ABIC score - Stratification of risk of death in AH
|
Dominguez M, Rincón D, et al. created a scoring system that predicts the risk
of death in patients with alcoholic hepatitis (AH) at 90 days and 1 year based
on four easily obtained monitoring parameters: Age, serum Bilirubin,
INR, and
serum Creatinine - (ABIC) score.
This score, along with other scoring systems, has aided in the management of
patients with alcoholic hepatitis. It has also been found to be a useful
tool in clinical trials.1
ABIC Score
ABIC Score = (age x 0.1) + (serum
bilirubin x 0.08) + (serum creatinine x 0.3) + (INR x 0.8). Age in
years, bilirubin (mg/dL), and creatinine (mg/dL). |

Interpretation:
ABIC cutoff values of 6.71 and 9 were identified as key values in
estimating survival rates at 90 days and 1 year.2 There risk
groups were created: ABIC score < 6.71: LOW risk;
ABIC score 6.71 - <9: INTERMEDIATE risk; and finally ABIC score>9: High risk.
Survival rates at 90 days: Low risk: 100%; Intermediate risk: 70%;
High risk: 25%.
"A higher ABIC cut-off of 9.5 compared to original cut-off of 9
resulted in an increased specificity of 90 % vs. 80 % and 95 % vs. 84 % for a
30- and 90-day outcome respectively."2
Assessing 1 year mortality with this tool can be used to aid decision making
regarding liver transplantation assignment. 2
Steroid therapy:
"Analysis of the subgroup of patients treated with steroids showed that the
greatest response was in the group with intermediate ABIC score (between
6.71–8.99) compared to those with either low ABIC (<6.71) or high ABIC scores
(>9). In patients treated with steroids, the ABIC score at 7 days has a better
accuracy than the Lille model in predicting mortality at 6 months." 2
