Are you ready to calculate your Lille Score? Let’s get started! This score is a way to measure liver damage in patients with chronic liver diseases. But don’t worry, we’ll make it easy for you.

Introduction

The Lille Score calculation formula is as follows: Lille Score = (0.1 x [Age (years) – 54]) + (0.01 x [BMI (kg/m2) – 25]) + (0.142 x [Serum albumin (g/dL) – 2.8]) + (−0.066 x [Prothrombin time ratio]) + (0.133 x [Serum bilirubin (mg/dL) – 5]) + (−0.206 x [Serum creatinine (mg/dL) – 1.2]) + (0.006 x [AST (IU/L) – 100]) + (−0.009 x [WBC count (×109/L) – 6]).

Lille Score Categories and Interpretation

Here is a table outlining different categories, types, range, and levels of Lille Score calculations and their interpretation:

Lille Score Interpretation
< 0.16 Very good response
0.16 – 0.30 Good response
0.31 – 0.49 Poor response
> 0.49 Very poor response

Lille Score Calculation Examples

Let’s see some examples of Lille Score calculations for different individuals!

Age (years) BMI (kg/m2) Serum albumin (g/dL) Prothrombin time ratio Serum bilirubin (mg/dL) Serum creatinine (mg/dL) AST (IU/L) WBC count (×109/L) Lille Score
45 24 3.2 1.2 2.3 0.8 80 5.5 0.15
58 26 2.5 1.3 5.6 1.1 120 7.0 0.68
36 21 4.0 1.1 1.2 0.7 90 6.0 0.12

Different Ways to Calculate Lille Score

There are two different ways to calculate Lille Score, based on different time points. Here is a table outlining the advantages, disadvantages, and accuracy levels for each method:

Method Advantages Disadvantages Accuracy
Day 0 Quick calculation, easy to interpret Limited by the short duration of treatment Low
Day 7 Longer duration of treatment, more accurate More complex calculation High

Evolution of Lille Score Calculation

The Lille Score calculation has evolved over time to include more factors and become more accurate. Here is a table highlighting the changes made to the formula:

Year Changes
2004 Original Lille Score formula
2011 Addition of serum creatinine and AST
2015 Addition of WBC count

Limitations of Lille Score Calculation Accuracy

Here are some limitations of Lille Score calculation accuracy:

  1. Patient variability: Patient characteristics can vary widely, making it difficult to predict response to treatment accurately.
  2. Sampling error: Variations in lab measurements can impact the score.
  3. Treatment duration: The score is less accurate for short treatment durations.

Alternative Methods for Measuring Lille Score

There are different methods for measuring Lille Score, including APRI, FIB-4, and FibroTest. Here is a table outlining the pros and cons of each method:

Method Pros Cons
APRI Simple calculation, widely available Less accurate than other methods
FIB-4 Simple calculation, widely available Limited to patients with hepatitis C
FibroTest More accurate than other methods Expensive, not widely available
