Fill in every field to see the result.

Only meaningful after 7 days of corticosteroids. Prothrombin time in seconds, not INR.

Interpretation

< 0.45 — responderAbout 85 % 6-month survival in the derivation study; Louvet 2007 describes continuing corticosteroids in responders.
≥ 0.45 — non-responderAbout 25 % 6-month survival; Louvet 2007 describes stopping corticosteroids in non-responders.

What is the Lille model?

The Lille model predicts 6-month survival in severe alcohol-associated hepatitis after 7 days of corticosteroids, using the early change in bilirubin with age, albumin, renal function and prothrombin time. Louvet and colleagues in Lille, France, developed it in 2007; a score of 0.45 or more identifies non-responders.

When to use it

  • Day 7 of corticosteroid treatment for severe alcohol-associated hepatitis
  • Deciding whether to stop corticosteroids
  • Stratifying patients for trials of alternative treatments

When not to use it

  • Before corticosteroids have been given for 7 days
  • Hepatitis of other causes

How it is calculated

R = 3.19 − 0.101 × age + 0.147 × albumin (g/L) + 0.0165 × (bilirubin d0 − d7, µmol/L) − 0.206 × renal insufficiency − 0.0065 × bilirubin d0 − 0.0096 × PT (s); Lille = e^−R / (1 + e^−R).

Clinical pearls and limitations

  • Only meaningful after 7 days of corticosteroids. Prothrombin time in seconds, not INR.
  • Lille ≥ 0.45: about 25 % 6-month survival versus about 85 % below 0.45 in the original study.
  • The bilirubin fall between day 0 and day 7 carries most of the information.
  • All lab inputs are in SI units (µmol/L, g/L) as in the source; PT in seconds.

Frequently asked questions

What Lille score means non-response?

A score of 0.45 or higher indicates non-response to corticosteroids.

When is the Lille model calculated?

On day 7 of corticosteroid therapy (some studies have used day 4).

What counts as renal insufficiency in the Lille model?

Serum creatinine above 1.3 mg/dL (115 µmol/L).
