Endothelial dysfunction markers predict short-term mortality in patients with severe alcoholic hepatitis

Area of Science:

• Hepatology
• Vascular Biology
• Biomarker Discovery

Background:

• Alcoholic hepatitis (AH) is a severe liver condition with high short-term mortality.
• Endothelial dysfunction (ED) is an early indicator in vascular and inflammatory diseases.
• Evaluating ED in AH patients is crucial for understanding disease progression and mortality.

Purpose of the Study:

• To assess endothelial dysfunction (ED) biomarkers in patients with alcoholic hepatitis (AH).
• To determine the prognostic value of ED biomarkers in severe AH.
• To investigate the association between ED markers and disease severity and outcomes.

Main Methods:

• Assessed ED biomarkers (VCAM-1, ICAM-1, E-selectin, vWF) in severe AH, compensated cirrhosis, heavy drinkers, and controls.
• Analyzed gene expression of ED markers in liver tissue.
• Validated findings in an independent cohort of AH patients.

Main Results:

• Plasma levels of ED markers increased with alcohol-related liver disease (ALD) progression.
• AH patients showed significantly higher levels of ED markers compared to other groups.
• VCAM-1 levels correlated positively with disease severity scores (Maddrey, MELD, ABIC) and inflammation markers.
• Elevated VCAM-1 was associated with increased mortality and independently predicted short-term survival in AH patients.
• Altered hepatic expression of ED markers was observed in severe AH.

Conclusions:

• Advanced ALD and severe AH are linked to increased endothelial dysfunction (ED) biomarkers.
• ED biomarkers, particularly VCAM-1, correlate with patient outcomes and mortality in AH.
• Endothelial dysfunction may play a pathogenic role in AH, highlighting endothelial factors as potential biomarkers.
