Alcoholic Hepatitis Lille Score

Predicts mortality risk in patients diagnosed with alcoholic hepatitis that is not responding to steroid therapy.

You can read more about the prediction method and about the original study in the text below the calculator.


The alcoholic hepatitis Lille score stratifies mortality risk in patients who are under treatment with steroids (for at least 7 days).

The Lille model helps determine which of the non-responders to steroid treatment have a poor prognosis, thus directing clinicians towards alternative ways of treatment.

There are four determinations required (albumin, creatinine, prothrombin time and bilirubin) the first three at admission and bilirubin both at admission and after 7 days of steroid therapy.


Lille Model Score = Exp(-R) / (1 + Exp(-R))

Where:

R = [3.19 - (0.101 x Age in years)] + (1.47 x Albumin in g/dL) + [0.28215 x (Bilirubin initial - Bilirubin day7 in mg/dL)] - (0.206 x Creatinine in mg/dL) - (0.11115 x Bilirubin initial in mg/dL) - (0.0096 x Prothrombin time in seconds)

Lille model explained

The Lille model stratifies mortality risk in alcoholic hepatitis patients who don’t respond to steroid treatment.

It is a model based on parameters tested at admission and on subsequent bilirubin determinations. The variables used in the model are explained in the table below:

Lille model variable Description
Patient age Age is an important indicator of adverse outcome.
Albumin in g/dL Albumin serum determination offers information about liver function.
Bilirubin levels at admission and day 7 in mg/dL or µmol/L The bilirubin level is determined for monitoring purposes and to check whether the patient responded to steroid therapy.
Creatinine in mg/dL or µmol/L Checks the clearance job of the kidneys
Prothrombin time in seconds Indirectly verifies liver function (based on the action of coagulation factors)

The formula used in the Lille model accounts for the above variables by awarding them different weights, depending on the individual predictor value.

Lille Model Score = Exp(-R) / (1 + Exp(-R))

Where:

R = [3.19 - (0.101 x Age in years)] + (1.47 x Albumin in g/dL) + [0.28215 x (Bilirubin initial - Bilirubin day 7 in mg/dL)] - (0.206 x Creatinine in mg/dL) - (0.11115 x Bilirubin initial in mg/dL) - (0.0096 x Prothrombin time in seconds)

 

Alcoholic hepatitis prognosis

The Lille model provides an outcome prognostic in patients with alcoholic hepatitis that is unresponsive to corticosteroids at around 7 days since the therapy has begun.

The model is often used in association with the Maddrey score (for scores above 32), when the administration of treatment is urgent.

The subsequent bilirubin determinations can indicate whether poor prognosis is likely. The Lille model provides a cut off at 0.45:

■ Scores below 0.45 are consistent with a 6-month survival rate of 85%;

■ Scores above 0.45 indicate a 6-month survival rate of 25%.

If the patient scores above 0.45, alternative therapies should be considered, as well as referring the patient for a transplant waiting list.

There are other prognosis models for hepatic disease, such as the Model for End-Stage Liver Disease (MELD) or the Child-Pugh severity score.

 

About the study

The Lille model was created by Louvet et al. in 2007 and was aimed at early identification of patients with severe alcoholic hepatitis, not responding to corticosteroids.

The evolution of 320 patients in the development cohort and of 118 patients in the validation program, was supervised. The model was generated by logistic regression and ended up combining six reproducible variables, that were found statistically relevant for 6 month prognosis.

The area under the receiver operating characteristic (AUROC) curve of the model was found to be higher than that of other models (Maddrey and Child-Pugh) in the derivation cohort whilst in the validation cohort, Lille AUROC was higher than that of MELD.

The application of the Lille model can improve management of patients with severe alcoholic hepatitis.
