Abstract

Insights

Serum S100B protein levels correlate with minimal hepatic encephalopathy (MHE) symptoms. Elevated S100B protein was observed in most MHE patients, suggesting its potential as a diagnostic biomarker.

Area of Science:

  • Neurology
  • Hepatology
  • Biochemistry

Background:

  • Minimal hepatic encephalopathy (MHE) is a central nervous system impairment in liver disease patients.
  • MHE significantly impacts quality of life and prognosis, often preceding overt hepatic encephalopathy.
  • Diagnostic challenges highlight the need for reliable serum biomarkers for MHE.

Purpose of the Study:

  • To investigate the correlation between serum S100B protein levels and MHE.
  • To assess the potential of S100B protein as a biomarker for MHE diagnosis.

Main Methods:

  • Serum S100B protein levels were measured in patients diagnosed with MHE.
  • Diagnosis of MHE was confirmed using the Psychometric Hepatic Encephalopathy Score (PHES) test.

Main Results:

  • A statistically significant correlation was found between serum S100B protein levels and PHES test results.
  • Elevated serum S100B protein levels, above the healthy population norm, were detected in 83% of MHE patients.

Conclusions:

  • Serum S100B protein shows a promising correlation with MHE.
  • Further research is warranted to validate S100B protein as a specific biomarker for MHE.
