Summary

A new galactose single point (GSP) test offers a simple, quantitative measure of liver function. This test effectively differentiates healthy individuals from those with chronic hepatitis, cirrhosis, or hepatocellular carcinoma, aiding in prognosis and treatment decisions.

Area of Science:

  • Hepatology
  • Clinical Chemistry
  • Diagnostic Medicine

Background:

  • Accurate assessment of liver function is crucial for managing liver diseases.
  • Existing quantitative liver function tests can be complex or invasive.
  • There is a need for simple, clinically applicable methods to evaluate residual liver function.

Purpose of the Study:

  • To develop and validate a novel, simple, quantitative liver function test.
  • To assess the diagnostic capability of the galactose single point (GSP) method in differentiating liver disease states.
  • To correlate GSP results with established liver function parameters and disease severity.

Main Methods:

  • Development of the galactose single point (GSP) method measuring blood galactose 1 hour after intravenous administration (0.5 g/kg).

Related Experiment Videos

  • Intravenous galactose infusion in 55 healthy volunteers, 73 chronic hepatitis (CH), 36 cirrhosis, and 41 hepatocellular carcinoma (HCC) patients.
  • Comparison of GSP values with galactose elimination capacity (GEC), modified GEC (MGEC), and clinical/biochemical liver function markers (AST, ALT, bilirubin, albumin, prothrombin time, r-globulin).

    • Main Results:

    • Highly significant differences in GSP values were observed between healthy volunteers and patients with CH, cirrhosis, and HCC (p < 0.001).
    • Average GSP values were 247 ± 18.1, 422 ± 27.3, 629 ± 42.8, and 579 ± 43.6 µg/ml for healthy, CH, cirrhosis, and HCC groups, respectively.
    • Significant correlations were found between GSP, GEC, MGEC, and various liver function markers, indicating its quantitative accuracy.

    Conclusions:

    • The galactose single point (GSP) method is a simple, clinically useful quantitative liver function test.
    • GSP can effectively determine residual liver function, prognosis in cirrhosis, aid in post-operative follow-up, and inform liver transplant timing.
    • The GSP method demonstrates high diagnostic accuracy and correlation with established liver function assessments.
