Summary

This study introduces a new multiparametric analysis using indocyanine green (ICG) and bromosulfalein (BSP) dye kinetics to evaluate liver function. The method aids in differentiating and staging liver diseases based on clearance values.

Area of Science:

Hepatology
Clinical Chemistry
Biomedical Engineering

Background:

Liver disease diagnosis relies on accurate functional assessment.
Current methods may lack precision in differentiating disease types and stages.
Dye kinetics offer a potential window into liver function.

Purpose of the Study:

To develop and evaluate a novel multiparametric analysis for liver function.
To assess the utility of indocyanine green (ICG) and bromosulfalein (BSP) dye kinetics.
To correlate dye clearance values with liver disease differentiation and clinical staging.

Main Methods:

Bolus injection of indocyanine green (ICG) and bromosulfalein (BSP).
Spectrophotometric measurement of BSP in plasma.
Pulse dye densitometry for ICG evaluation.
Analysis of dye clearance kinetics.

Main Results:

Established a new method for multiparametric analysis of dye kinetics.
Demonstrated the ability to differentiate various liver diseases.
Showed potential for clinical staging of liver pathologies.
Provided insights into sinusoidal and canalicular membrane transfer in dye kinetics.

Conclusions:

The developed multiparametric analysis offers a valuable tool for liver disease assessment.
ICG and BSP kinetics provide crucial data for differentiating and staging liver conditions.
Understanding dye transport mechanisms enhances diagnostic capabilities.
