Introduction

The Lille Score Calculator shows whether a patient with severe alcohol-related hepatitis is getting better on steroid treatment. After 7 days of steroids, the score tells you if the drug is working.

The score uses six things: age, albumin, bilirubin on day 0, bilirubin on day 7, creatinine, and prothrombin time (or INR). The calculator turns these into one number between 0 and 1.

A score under 0.45 means the patient is a responder. About 85% live at least 6 more months. A score of 0.45 or higher means the patient is a non-responder. About 25% live at least 6 more months. In that case, the care team may stop steroids and look at other plans, like a transplant referral.

Enter your lab values below in mg/dL, µmol/L, g/L, or g/dL. The tool converts units, shows the full math step by step, and flags values that look odd. Use it with your own clinical judgment, not in place of it.

How to use our Lille Score Calculator

Enter your patient's age, lab values from Day 0 of steroid treatment, and the bilirubin drawn on Day 7. The calculator returns the Lille score (0 to 1), tells you if the patient is a steroid responder or non-responder, shows the 6-month survival estimate, and gives a step-by-step breakdown of the math.

Age (years): Type the patient's age in whole years on the day steroids were started. If you would rather use a birth date, press "Switch to Date of Birth Entry" and pick the date. The age fills in for you.

Date of Admission / Day 0 (optional): Pick the day steroid therapy began. The tool then shows you the date the Day 7 bilirubin should be drawn. This date does not change the score.

Albumin at Day 0: Choose g/L or g/dL, then enter the serum albumin from the first day of treatment. If the patient got albumin infusions, use the value taken before the infusion.

Creatinine at Day 0: Choose mg/dL or µmol/L, then enter the creatinine. The score only checks if it is above 1.3 mg/dL (115 µmol/L), which counts as kidney trouble.

Bilirubin at Admission (Day 0): Choose mg/dL or µmol/L, then enter the total bilirubin from the day steroids started.

Bilirubin at Day 7: Enter the total bilirubin after 7 days of steroids. A drop from Day 0 is the main sign the patient is getting better. Use the "Switch both bilirubin fields" button to change both units at once.

Coagulation (PT or INR): Pick "Prothrombin Time (sec)" and enter the patient PT plus your lab's control PT. If you only have an INR, pick "INR" and enter it. The tool changes INR to seconds using a 12-second control.

What Is the Lille Score?

The Lille Score shows whether a patient with severe alcohol-associated hepatitis (also called alcoholic hepatitis) is getting better on steroid medicine. It is checked after 7 full days of steroid treatment. The score is a number between 0 and 1. A lower number is better.

Why Day 7 Matters

Steroids like prednisolone can help some people with severe liver swelling from alcohol. But they do not help everyone, and they raise the risk of infection. The Lille Score uses one week of data to show who is responding. This lets the care team stop steroids early in people who are not being helped.

What the Score Uses

  • Age: older age lowers the chance of a good outcome.
  • Albumin on Day 0: a blood protein made by the liver. Higher is better.
  • Bilirubin on Day 0 and Day 7: the yellow pigment that causes jaundice. A drop over 7 days is a good sign.
  • Creatinine on Day 0: shows kidney trouble. Above 1.3 mg/dL (115 µmol/L) counts as kidney problems.
  • Prothrombin time (or INR): how fast blood clots. Slow clotting means worse liver damage.

How to Read the Result

The cut-off is 0.45.

  • Score under 0.45: responder. About 85% of these patients are alive at 6 months. Steroids are usually continued for the full course.
  • Score 0.45 or higher: non-responder. About 25% are alive at 6 months. Doctors often stop steroids and think about other care, such as a liver transplant referral, a clinical trial, or comfort-focused care.

Things to Keep in Mind

The Lille Score is made for patients who started steroids for severe alcohol-associated hepatitis, usually those with a Maddrey Discriminant Function of 32 or more. It is not meant for other liver diseases. If a patient was given albumin through an IV, use the albumin level drawn before that infusion. Other things can raise bilirubin too, such as an infection, bile duct blockage, or another drug, so the number should always be read next to the full clinical picture. The score supports a decision. It does not make it.

Where It Comes From

The score was created by Louvet and colleagues in Lille, France, and published in 2007. It has been tested in many groups of patients since then and is used in liver care guidelines around the world.

Frequently asked questions

What is the Lille score formula?

The Lille score comes from two steps. First you build a number called R:

R = 3.19 − (0.101 × age) + (1.47 × albumin in g/dL) + (0.28215 × bilirubin drop in mg/dL) − (0.206 × kidney flag) − (0.11115 × day 0 bilirubin in mg/dL) − (0.0096 × prothrombin time in seconds)

The kidney flag is 1 if creatinine is above 1.3 mg/dL, and 0 if it is not.

Then R is turned into a score from 0 to 1:

Lille = e−R ÷ (1 + e−R)

What is a complete, partial, and null response on the Lille score?

Doctors sometimes split the score into three groups instead of two:

  • Complete responder: score 0.16 or less. About 87% are alive at 6 months.
  • Partial responder: score between 0.16 and 0.56. About 70% are alive at 6 months.
  • Null responder: score 0.56 or higher. Only about 21% are alive at 6 months.

The single 0.45 cut-off is still the one used most often for stopping or continuing steroids.

Can the Lille score be checked on day 4 instead of day 7?

Yes. A Lille score built from a day 4 bilirubin predicts 6-month survival about as well as the day 7 score. That lets the team stop useless steroids three days sooner and cut the infection risk.

Day 7 is still the standard timing used in guidelines, so many teams check day 4 early and confirm at day 7.

What is the difference between the Maddrey discriminant function and the Lille score?

They are used at different times.

  • Maddrey DF is used before treatment. A value of 32 or more means the hepatitis is severe and steroids may help.
  • Lille score is used after 7 days of steroids. It shows whether the drug is actually working.

So Maddrey helps you start treatment, and Lille helps you decide to keep going or stop.

How long is prednisolone given for alcohol-related hepatitis?

The usual plan is prednisolone 40 mg by mouth each day for 28 days. Some teams then taper the dose over 2 to 3 weeks, and others just stop.

At day 7, the Lille score is checked. If the score is 0.45 or higher, steroids are usually stopped early because they are not helping and they raise infection risk.

Why is prednisolone used instead of prednisone in liver disease?

Prednisone is not active until the liver changes it into prednisolone. In a badly damaged liver that change may not work well.

Prednisolone is already in the active form, so it skips that step. That is why liver guidelines name prednisolone for severe alcohol-related hepatitis. Methylprednisolone by IV is used when a patient cannot swallow pills.

How do you convert bilirubin from µmol/L to mg/dL?

Divide by 17.1.

  • µmol/L ÷ 17.1 = mg/dL
  • mg/dL × 17.1 = µmol/L

For example, 250 µmol/L ÷ 17.1 = 14.6 mg/dL. The Lille formula was built with bilirubin in µmol/L, so units must match before you do the math.

Can someone with a high Lille score still get a liver transplant?

Yes, in some centers. Early liver transplant is offered to carefully picked non-responders who have strong family support, no other serious illness, and a first episode of alcohol-related hepatitis.

In these selected patients, 6-month survival runs near 70% to 80%, far better than the roughly 25% seen without transplant. Rules differ by center and country.

Does an infection change the Lille score?

It can. An infection, a blocked bile duct, or a new drug can push bilirubin up and make the score look worse than the liver really is.

Before reading the score as steroid failure, the team should look for infection, check imaging of the bile ducts, and review medicines. The number should always be read with the whole clinical picture.

Does the Lille score work for patients not taking steroids?

It was built and tested in patients on steroids, so that is where it belongs. In untreated patients a falling bilirubin is still a good sign, but the 0.45 cut-off and the survival numbers were not made for them.

For patients who are not on steroids, doctors usually lean on MELD, Maddrey DF, or Child-Pugh instead.

Why does the Lille score treat creatinine as yes or no instead of a number?

The original study found that simply having kidney trouble mattered more than the exact creatinine value. So the model uses a flag: 1 if creatinine is above 1.3 mg/dL (115 µmol/L), and 0 if it is at or below.

That means a creatinine of 1.5 and a creatinine of 3.0 push the score the same way. Kidney failure is still a serious warning sign on its own.

What counts as severe alcohol-related hepatitis?

Severe disease usually means a Maddrey discriminant function of 32 or more, or a MELD score above 20. Most patients have jaundice that started within the last 3 months, heavy recent drinking, AST higher than ALT (both usually under 400), and a raised bilirubin.

Only patients in this severe group are considered for steroids, and only they should have a Lille score checked.
