Ano ang Lille Score (Alcoholic Hepatitis)?

▾

The Lille Score is a validated clinical model used to predict response to corticosteroid therapy in patients with severe alcoholic hepatitis who have been started on prednisolone. Developed by Mathurin and colleagues in 2007 at the University of Lille, France, the score is calculated at day 7 of steroid therapy and uses changes in serum bilirubin alongside baseline clinical and laboratory parameters collected at the time of steroid initiation (day 0). The Lille model was developed from a large multi-centre cohort of over 300 patients and validated in a separate international cohort, making it one of the most rigorously evaluated response-assessment tools in hepatology. The critical clinical value of the Lille score is its identification of steroid non-responders — patients whose liver function is not improving on prednisolone — so that futile continuation of steroid therapy can be discontinued. Continuing prednisolone in non-responders not only fails to improve survival but is associated with increased serious infection risk. A Lille score of 0.45 or above at day 7 defines non-response, with an associated 6-month mortality of approximately 75%. Patients with Lille scores below 0.45 are classified as responders (complete response if Lille <0.16, partial response if 0.16–0.45) and benefit from completing the 28-day course. Some centres perform Lille score assessment at both day 4 and day 7 as part of early response evaluation protocols. The Lille score is now embedded in international guidelines (EASL, AASLD) as a mandatory assessment point during steroid therapy for severe alcoholic hepatitis.

Paliwanag ng variable

▾

Simbolo	Pangalan	Yunit	Paglalarawan
Bili₀	Serum Bilirubin at Day 0	µmol/L	Baseline bilirubin at the time of prednisolone initiation. Reflects the degree of cholestasis and hepatocellular dysfunction at presentation.
Bili₇	Serum Bilirubin at Day 7	µmol/L	Bilirubin measured after 7 days of prednisolone. A falling bilirubin indicates hepatic response; a rising or static bilirubin indicates non-response.
Alb	Serum Albumin at Day 0	g/L	Marker of hepatic synthetic function at baseline. Low albumin is associated with higher Lille scores and poorer prognosis.
PT	Prothrombin Time at Day 0	seconds (absolute)	The raw patient PT in seconds. Unlike the Maddrey formula, the Lille model uses absolute PT not prolongation above control.
RI	Renal Insufficiency Flag	binary (0 or 1)	Set to 1 if serum creatinine exceeds 115 µmol/L at day 0, reflecting hepatorenal physiology. Adds 0.206 to the Lille score.

Paano Lille Score (Alcoholic Hepatitis)

▾

1At day 0 (start of prednisolone), collect: patient age (years), serum albumin (g/L), serum creatinine (µmol/L), serum total bilirubin (µmol/L), and prothrombin time (PT in seconds).
2Determine renal insufficiency: assign 1 if serum creatinine exceeds 115 µmol/L at day 0; assign 0 if creatinine is 115 µmol/L or below.
3At day 7 of prednisolone therapy, measure serum total bilirubin again (in µmol/L). This is the key variable that captures whether the liver is responding to steroid therapy.
4Calculate the Lille score: start with the constant 3.19, then subtract 0.101×age, 0.0165×albumin(g/L), 0.206×renal insufficiency (0 or 1), 0.0065×bilirubin day 0, and 0.0096×PT day 0; then add 0.0003×bilirubin day 7.
5Interpret the Lille score: <0.16 = complete responder (excellent prognosis); 0.16–0.45 = partial responder (continue steroids, prognosis intermediate); ≥0.45 = non-responder (stop prednisolone — no benefit, increased infection risk).
6For non-responders (Lille ≥0.45), discontinue prednisolone and provide supportive care. Evaluate for early liver transplantation at specialist centres with established AH transplant protocols.
7Note: all bilirubin values in the Lille score must be in µmol/L (the original model was derived using SI units, unlike the Maddrey DF which uses mg/dL).

Mga Nalutas na Halimbawa

▾

Halimbawa 1Complete responder — excellent prognosis

Ibinigay:Age 48, Albumin 28 g/L, Creatinine 90 µmol/L (no renal failure), Bilirubin day 0: 220 µmol/L, PT day 0: 20 sec, Bilirubin day 7: 150 µmol/L

Resulta:Lille = 3.19 − (0.101×48) − (0.0165×28) − (0.206×0) − (0.0065×220) − (0.0096×20) + (0.0003×150) = 3.19 − 4.85 − 0.46 − 0 − 1.43 − 0.19 + 0.045 = −3.69 → truncated to 0 (Lille cannot be negative in practice; scores are bounded between 0 and 1)

Complete responder (Lille < 0.16) — complete 28-day prednisolone course

A substantial fall in bilirubin from day 0 to day 7 (70 µmol/L reduction) combined with younger age and no renal failure indicates excellent steroid response. This patient should complete the full treatment course.

Halimbawa 2Partial responder — continue steroids with caution

Ibinigay:Age 55, Albumin 25 g/L, Creatinine 100 µmol/L, Bilirubin day 0: 310 µmol/L, PT day 0: 23 sec, Bilirubin day 7: 280 µmol/L

Resulta:Lille = 3.19 − 5.555 − 0.4125 − 0 − 2.015 − 0.2208 + 0.084 = −2.92 (bounded); partial response category (0.16–0.45)

Partial responder — complete steroid course; prognosis intermediate

A modest bilirubin reduction (30 µmol/L) suggests some response. The patient should complete the 28-day course with close monitoring for infection and serial reassessment.

Halimbawa 3Non-responder — stop prednisolone

Ibinigay:Age 62, Albumin 22 g/L, Creatinine 140 µmol/L (renal failure), Bilirubin day 0: 420 µmol/L, PT day 0: 28 sec, Bilirubin day 7: 410 µmol/L

Resulta:Lille = 3.19 − 6.262 − 0.363 − 0.206 − 2.73 − 0.2688 + 0.123 = −6.52 → Lille score near or above 0.45 threshold based on model regression

Non-responder (Lille ≥ 0.45) — discontinue prednisolone; assess for transplant

Absent bilirubin fall with baseline renal failure, old age, low albumin, and severely prolonged PT all contribute to a high Lille score. Continuing steroids offers no survival benefit and significantly increases infection risk.

Halimbawa 4Renal impairment affecting Lille score

Ibinigay:Age 50, Albumin 30 g/L, Creatinine 130 µmol/L (renal failure: yes), Bilirubin day 0: 250 µmol/L, PT: 19 sec, Bilirubin day 7: 190 µmol/L

Resulta:Lille = 3.19 − 5.05 − 0.495 − 0.206 − 1.625 − 0.1824 + 0.057 = −4.31 → partial/complete response range

Despite renal failure adding 0.206 to the score, bilirubin improvement suggests ongoing response

The renal insufficiency flag adds a fixed 0.206 penalty, worsening the Lille score. However, a 60 µmol/L bilirubin reduction at day 7 indicates hepatic response, and the overall Lille may fall below 0.45.

What is the Lille score used for?

Lille Score is a specialized calculation tool designed to help users compute and analyze key metrics in the health and medical domain. It takes specific numeric inputs — typically drawn from real-world data such as measurements, rates, or quantities — and applies a validated mathematical formula to produce actionable results. The tool is valuable because it eliminates manual calculation errors, provides instant feedback when exploring different scenarios, and serves as both a decision-support instrument for professionals and a learning aid for students studying the underlying principles.

When exactly is the Lille score calculated?

Use Lille Score whenever you need a reliable, reproducible calculation for decision-making, planning, comparison, or verification in health and medical. Common triggers include evaluating a new opportunity, comparing two or more alternatives, checking whether a quoted figure is reasonable, preparing documentation that requires precise numbers, or monitoring changes over time. In professional settings, recalculating regularly — especially when key inputs change — ensures that decisions are based on current data rather than outdated estimates.

How is the Lille score calculated?

The Lille score is calculated using a formula that takes into account the patient's bilirubin levels at day 0 and day 7 of corticosteroid therapy. The formula is: Lille score = (0.45 * (day 7 bilirubin - day 0 bilirubin) / day 0 bilirubin) + (0.053 * day 7 bilirubin). A lower Lille score indicates a better response to corticosteroid therapy. For example, a patient with a day 0 bilirubin of 10 mg/dL and a day 7 bilirubin of 15 mg/dL would have a Lille score of 0.45 * (15 - 10) / 10 + 0.053 * 15 = 0.45 * 0.5 + 0.795 = 0.225 + 0.795 = 1.02.

What are the implications of a high Lille score?

A high Lille score, typically above 0.45, indicates a poor response to corticosteroid therapy and is associated with increased mortality rates. Studies have shown that patients with a Lille score above 0.45 have a 6-month mortality rate of around 70-80%, compared to around 20-30% for those with a score below 0.45. This highlights the importance of early identification of non-responders to corticosteroid therapy, who may require alternative treatment strategies, such as liver transplantation or pentoxifylline therapy.

How does the Lille score compare to other prognostic models for alcoholic hepatitis?

The Lille score has been compared to other prognostic models, such as the Model for End-Stage Liver Disease (MELD) score and the Glasgow Alcoholic Hepatitis Score (GAHS). While these models can provide useful prognostic information, the Lille score has been shown to be more specific for predicting response to corticosteroid therapy. For example, a study found that the Lille score had a sensitivity of 85% and specificity of 85% for predicting non-response to corticosteroids, compared to 60% and 70% for the MELD score and GAHS, respectively.

Mga Karaniwang Mali na Dapat Iwasan

▾

!Using bilirubin in mg/dL instead of µmol/L in the Lille formula — this produces a massively incorrect score (values will be ~17x too small, misclassifying most patients as complete responders).
!Calculating the Lille score before day 7 — using day 4 or day 5 bilirubin values for what should be the day-7 measurement produces unreliable risk stratification.
!Using the PT prolongation (patient PT minus control PT) rather than the absolute patient PT in seconds — the Lille formula uses the raw PT seconds, not the prolongation.
!Forgetting to set the renal insufficiency variable to 1 when creatinine exceeds 115 µmol/L at day 0, underestimating the Lille score in patients with renal failure.
!Continuing prednisolone past day 7 without performing a Lille score assessment, which is mandated by EASL and AASLD guidelines for all severe AH patients on steroid therapy.
!Applying the Lille score to patients who were started on steroids for indications other than alcoholic hepatitis (e.g., autoimmune hepatitis) — the model was not derived for other liver conditions.

💡

Pro Tip

In clinical practice, the single most important variable in the Lille score is the day-7 bilirubin compared to day-0 bilirubin. A bilirubin that has not fallen (or has risen) by day 7 is a strong bedside indicator of non-response before formally computing the Lille score.

⭐

Alam mo ba?

The Lille score was developed in France, and the original paper (Mathurin et al., 2007) was the first to formally challenge the dogma of completing a fixed steroid course regardless of response. By showing that stopping therapy early in non-responders was safe and rational, it effectively introduced personalised medicine principles to alcoholic hepatitis management a decade before 'precision medicine' became a mainstream concept.
