Modest alcohol intake and mortality in individuals with elevated alanine aminotransferase levels: a nationwide cohort study

Abstract

Background: Alanine aminotransferase (ALT) levels are widely used to screen liver disease, and many asymptomatic individuals show elevated ALT levels. As elevated ALT level indicates liver injury, even a small amount of alcohol intake may be harmful in subjects with elevated ALT levels, but there is limited evidence of the effect of light to moderate amount of alcohol intake in this subgroup.

 

Methods: A cohort of 367,612 men and women without established liver diseases (including chronic viral hepatitis, alcohol-associated liver disease, cirrhosis, liver transplantation, or rare forms of liver disease) who underwent at least 1 health screening exam between 2009 and 2015 were assessed for liver-related and all-cause mortality. Elevated ALT levels were defined as 34 U/L for men and 25 U/L for women.

 

Results: In participants with normal ALT levels, the fully-adjusted hazard ratios (95% CI) for liver-related mortality comparing light and moderate drinkers to non-drinkers were 0.73 (0.51-1.05), and 1.06 (0.73-1.52), respectively. In participants with elevated ALT levels, the corresponding hazard ratios were 1.57 (1.08-2.28), and 2.09 (CI 1.46-2.99), respectively (p value for alcohol intake by ALT interaction < 0.01). For all-cause mortality, the fully-adjusted hazard ratios comparing light and moderate drinkers to non-drinkers in participants with normal ALT levels were 0.72 (0.66-0.77), and 0.89 (0.82-0.97), respectively. In participants with elevated ALT levels, the corresponding hazard ratios were 0.93 (0.81-1.08), and 1.31 (1.14-1.50), respectively (p value for alcohol intake by ALT interaction < 0.01).

 

Conclusions: Small amounts of alcohol intake were associated with increased liver-related and all-cause mortality among individuals with elevated ALT levels. Subjects with elevated ALT levels should be advised complete abstinence from alcohol.
