Elevated blood monocyte counts in alcohol-associated hepatitis

Area of Science:

• Hepatology
• Immunology
• Clinical Medicine

Background:

• Alcohol-associated hepatitis (AH) is a severe liver disease with high mortality.
• Monocytes play a role in inflammatory liver diseases.
• Biomarkers are needed to assess AH severity.

Purpose of the Study:

• To investigate the association between absolute monocyte count and disease severity in patients with alcohol-associated hepatitis.
• To determine if absolute monocyte count can serve as a potential biomarker for AH.

Main Methods:

• Retrospective study of 164 patients diagnosed with alcohol-associated hepatitis.
• Analysis of absolute monocyte counts and correlation with established severity scores.
• Statistical analysis including calculation of Pearson correlation coefficients (R) and P-values.

Main Results:

• The mean absolute monocyte count in patients with AH was 0.95 thousand cells/L, significantly higher than the normal upper limit (0.80 thousand cells/μL; P < 0.0001).
• Absolute monocyte count showed a significant positive correlation with MELD score (R = 0.400, P < 0.0001).
• Absolute monocyte count also demonstrated a significant positive correlation with Maddrey discriminant function (R = 0.330, P < 0.0001).

Conclusions:

• Absolute monocyte count is significantly elevated in patients with alcohol-associated hepatitis.
• Elevated monocyte counts are correlated with established measures of AH disease severity, including MELD score and Maddrey discriminant function.
• Absolute monocyte count may represent a useful and accessible biomarker for assessing disease severity in alcohol-associated hepatitis.
